Michio Kaku dismisses the 2012 hysteria
Michio Kaku reassures us that the science of the theory behind the movie, that we'll be taken out due to planetary alignment, is blatantly lacking in credibility. (Hey, it's just like the fear tactics of the global warming hysteria!)
Dr. Michio Kaku: SCI FI or SCI FACT
Is telepathy possible? How about teleportation or starships? In this lecture, Dr. Michio Kaku (a frequent host on science shows for the Discovery Channel, PBS, and author of the best selling book "Physics of the Impossible") talks about many popular technologies in science fiction from a physics perspective, and what it would take to make many of these technologies a reality.
SCI FI or SCI FACT is part of a major lecture series at ASU on science presented by Beyond, the Center for Fundamental Concepts in Science. A center at the College of Liberal Arts and Sciences, Beyond seeks to create new and exciting ideas that push the boundaries of research and to answer foundational questions in science, and explore their philosophical ramifications what might be called the big questions

Benoit Mandelbrot - The nature of roughness in mathematics, science and art
Benoit Mandelbrot (Yale University, USA), "The nature of roughness in mathematics, science and art," Special Lecture, ICM 2006, Madrid, 27 Aug 2006.
50,000 Year-old North American Human Activity
Archeologists digging at the Topper site in South Carolina have produced strong evidence of human activity in North America 50,000 years ago (see article from ScienceDaily, 2004). These findings are creating much controversy in the archeological community as the foundations of the evolution of the Homo sapien say that human activity started in Africa between 60,000 and 80,000 years ago and that they eventually migrated to Australia and Europe where remains are found showing human activity 40,000 years ago. Then according to the standard model the Homo sapien crossed to North America 13,000 years ago. Although the author of this article is skeptical, the findings are solid and the carbon dating determined a minimal date of 50,000 years, widely contradicting the 13,000 years standard model for human activity in North America. These results are now being published in peer review journals.
If these new findings confirm human activity in North America as far back as 60,000 years ago, a new model of the evolution of man will be needed; one that demands a global evolution and may involve an external intervention as described in many different cultures and creation myths around the world. This global intervention may be related to the unusual skulls remains that are starting to be found in various regions of the world, and that many ancient cultures describe as the forefathers of our evolution in their creation myths (see recent post, Skulls of our Forefathers).

Skulls of our Forefathers
Archaeologists recently have found elongated skulls similar to the ones mentioned in DVD #3 of the “Crossing the Event Horizon” DVD set. These skulls however were found across the globe from South America, in Russia near the town of Omsk. They as well exhibit the same features as the ones in South America with their large elongated structure. This supports the fact that these remarkable remains of an ancient past were not only located in a particular region on earth, but were prevalent across the planet in many cultures that describe them as Sun Gods with their elongated skulls and unusual features.
Many of these cultures from South America, Native America and Egypt went on to attempt to deform their children’s skulls by banding them at birth to imitate the Sun Gods’ skull structures. This very important discovery in Siberia combined with similar skulls that were found in Iraq and France marks the beginning of the unraveling of an ancient history intricately linked with our evolution.

Antikythera Mechanism
Part 1: An Ancient Greek Computer?
In 1901 divers working off the isle of Antikythera found the remains of a clocklike mechanism 2,000 years old. The mechanism now appears to have been a device for calculating the motions of stars and planets by Derek J. de Solla Price [ From June 1959 Scientific American p.60-7 ]
Among the treasures of the Greek National Archaeological Museum in Athens are the remains of the most complex scientific object that has been preserved from antiquity. Corroded and crumbling from 2,000 years under the sea, its dials, gear wheels and inscribed plates present the historian with a tantalizing problem.
Nothing like this instrument is preserved elsewhere. Nothing comparable to it is known. from any ancient scientific text or literary allusion. On the contrary, from all that we know of science and technology in the Hellenistic Age we should have felt that such a device could not exist. Some historians have suggested that the Greeks were not interested in experiment because of a contempt-perhaps induced by the existence of the institution of slavery-for manual labor. On the other hand it has long been recognized that in abstract mathematics and in mathematical astronomy they were no beginners but rather "fellows of another college" who reached great heights of sophistication. Many of the Greek scientific devices known to us from written descriptions show much mathematical ingenuity, but in all cases the purely mechanical part of the design seems relatively crude. Gearing was clearly known to the Greeks, but it was used only in relatively simple applications. They employed pairs of gears to change angular speed or mechanical ad- vantage, or to apply power through a right angle, as in the water-driven mill.
Even the most complex mechanical devices described by the ancient writers Hero of Alexandria and Vitruvius contained only simple gearing. For example, the taximeter used by the Greeks to measure the distance travelled by the wheels of a carriage employed only pairs of gears (or gears and worms) to achieve the necessary ratio of movement. It could be argued that if the Greeks knew the principle of gearing, they should have had no difficulty in constructing mechanisms as complex as epicyclic gears. We now know from the fragments in the National Museum that the Greeks did make such mechanisms, but the knowledge is so unexpected that some scholars at first thought that the fragments must belong to some more modern device.
Can we in fact be sure that the device is ancient? If we can, what was its purpose? What can it tell us of the ancient world and of the evolution of modern science? To authenticate the dating of the fragments We must. tell the story of their discovery, which involves the first (though inadvertent) adventure in underwater archaeology. Just before Easter in 1900 a party of Dodecanese sponge-divers were driven by storm to anchor near the tiny southern Greek island of Antikythera (the accent is on the "kyth," pronounced to rhyme with pith). There, at a depth of some 200 feet, they found the wreck of an ancient ship. With the help of Greek archaeologists the wreck was explored; several fine bronze and marble statues and other objects were recovered. The finds created great excitement, but the difficulties of diving without heavy equipment were immense, and in September, 1901, the "dig' was abandoned. Eight months later Valerios StaÎs, an archaeologist at the National Museum, was examining some calcified lumps of corroded bronze that had been set aside as possible pieces of broken statuary. Suddenly he recognized among them the fragments of a mechanism.
It is now accepted that the wreck occurred during the first century B.C. Gladys Weinberg of Athens has been kind enough to report to me the results of several recent archaeological examinations of the amphorae, pottery and minor objects from the ship. It appears from her report that one might reason-ably date the wreck more closely as 65 B.C. ±15 years. Furthermore, since the identifiable objects come from Rhodes and Cos, it seems that the ship may have. been voyaging from these islands to Rome, perhaps without calling at the Greek mainland.
The fragment that first caught the eye of StaÎs was one of the corroded, inscribed plates that is an integral part of the Antikythera mechanism, as the device later came to be called. StaÎs saw immediately that the inscription was ancient. In the opinion of the epigrapher Benjamin Dean Meritt, the forms of the letters are those of the 'first century B.C.; they could hardly be older than 100 B.C. nor younger than the time of Christ. The dating is supported by the content of the inscriptions. The words used and their astronomical sense are all of this period. For example, the most extensive and complete piece of inscription is part of a parapegma (astronomical calendar) similar to that written by one Geminos, who is thought to have lived in Rhodes about 77 B.C. We may thus be reasonably sure that the mechanism did not find its way into the wreck at some later period. Furthermore, it cannot have been very old when it was taken aboard the ship as booty or merchandise.

Furthermore, it cannot have been very old when it was taken aboard the ship as booty or merchandise.
As soon as the fragments had been discovered they were examined by every available archaeologist; so began the long and difficult process of identifying the mechanism and determining its function. Some things were clear from the beginning. The unique importance of the object was obvious, and the gearing was impressively complex. From the inscriptions and the dials the mechanism was correctly identified as an astronomical device. The first conjecture was that it was some kind of navigating instrument – perhaps an astrolabe (a sort of circular star-finder map also used for simple observations). Some thought that it might be a small planetarium of the kind that Archirnedes is said to have made. Unfortunately the fragments were covered by a thick curtain of calcified material and corrosion products, and these concealed so much detail that no one could be sure of his conjectures or reconstructions. There was nothing to do but wait for the slow and delicate work of the Museum technicians in cleaning away this curtain. Meantime, as the work proceeded, several scholars published accounts of all that was visible, and through their labors a general picture of the mechanism began to emerge. On the basis of new photographs made for me by the Museum in 1955 I realized that the work of cleaning had reached a point where it might at last be possible to take the work of identification to a new level. Last summer, wilt the assistance of a grant from the American Philosophical Society, I was able to visit Athens and make a minute examination of the fragments. By good fortune George Stamires, a Greek epigrapher, was there at the same time; he was able to give me invaluable help by deciphering and transcribing much more of the inscriptions than had been read before. We are now in the position of being able to "join" the fragments and to see how they fitted together in the original machine and when they were brought up from the sea [see illustration]. The success of this work has been most significant, for previously it had been supposed that the various dials and plates had been badly squashed together and distorted. It now appears that most of the pieces are very nearly in their original places, and that we have a much larger fraction of the complete device than had been thought. This work also provides a clue to the puzzle of why the fragments lay unrecognized until StaÎs saw them. When they were found, the fragments were probably held together in their original positions by the remains of the wooden frame of the case. In the Museum the waterlogged wood dried and shriveled. The fragments then fell apart, revealing the interior of the mechanism, with its gears and inscribed plates. As a result of the new examinations we shall in due course be able to publish a technical account of the fragments and of the construction of the instrument. In the meantime we can tentatively summarize some of these results and show how they help to answer the question. What is it? There are four ways of getting at the answer First, if we knew the details of the mechanism, we should know what it did. Second, if we could read the dials, we could tell what they showed. Third, if we could understand the inscriptions, they might tell us about the mechanism. Fourth, if we knew of any similar mechanism, analogies might be helpful. All these approaches must be used, for none of them is complete.
The geared wheels within the mechanism were mounted on a bronze plate. On one side of the plate we can trace all the gear wheels of the assembly and can determine, at least approximately, how many teeth each had and how they meshed together. On the other side we can do nearly as well, but we still lack vital links that would provide a complete picture of the gearing. The general pattern of the mechanism is nonetheless quite clear. An input was provided by an axle that came through the side of the casing and turned a crown-gear wheel. This moved a big, four-spoked driving-wheel that was connected with two trains of gears that respectively led up and down the plate and were connected by axles to gears on the other side of the plate. On that side the gear-trains continued, leading through an epicyclic turntable and coming eventually to a set of shafts that turned the dial pointers. When the input axle was turned, the pointers all moved at various speeds around their dials.
Certain structural features of the mechanism deserve special attention. All the metal parts of the machine seem to have been cut from a single sheet of low-tin bronze about two millimeters thick; no parts were cast or made of another metal. There are indications that the maker may have used a sheet made much earlier–uniform metal plate of good quality was probably rare and expensive. All the gear wheels have been made with teeth of just the same angle (60 degrees) and size, so that any wheel could mesh with any other. There are signs that the machine was repaired at least twice; a spoke of the driving wheel has been mended, and a broken tooth in a small wheel has been replaced. This indicates that the machine actually worked. The casing was provided with three dials, one at the front and two at the back. The fragments of all of them are still covered with pieces of the doors of the casing and with other debris. Very little can be read on the dials, but there is hope that they can be cleaned sufficiently to provide information that might be decisive. The front dial is just clean enough to say exactly what it did. It has two scales, one of which is fixed and displays the names of the signs of the zodiac; the other is on a movable slip ring and shows the months of the year. Both scales are carefully marked off in degrees. The front dial fitted exactly over the main driving-wheel, which seems to have turned the pointer by means of an eccentric drum-assembly. Clearly this dial showed the annual motion of the sun in the zodiac. By means of key letters inscribed on the zodiac scale, corresponding to other letters on the parapegma calendar plate, it also showed the main risings and settings of bright stars and constellations throughout the year.
The back dials are more complex and less legible. The lower one had three slip rings; the upper, four. Each had a little subsidiary dial resembling the "seconds" dial of a watch. Each of the large dials is inscribed with lines about every six degrees, and between the lines there are letters and numbers. On the lower dial the letters and numbers seem to record "moon, so many hours; sun, so many hours"; we therefore suggest that this scale indicates the main lunar phenomena of phases and times of rising and setting. On the upper dial the inscriptions are much more crowded and might well present information on the risings and settings, stations and retrogradations of the planets known to the Greeks (Mercury, Venus, Mars, Jupiter and Saturn).
Some of the technical details of the dials are especially interesting. The front dial provides the only known extensive specimen from antiquity of a scientifically graduated instrument. When we measure the accuracy of the graduations under the microscope, we find that their average error over the visible 45 degrees is about a quarter of a degree. The way in which the error varies suggests that the arc was first geometrically divided and then subdivided by eye only. Even more important, this dial may give a means of dating the instrument astronomically. The slip ring is necessary because the old Egyptian calendar, having no leap years, fell into error by 1/4 day every year; the month scale thus had to be adjusted by this amount. As they are preserved the two scales of the dial are out of phase by 13½ degrees. Standard tables show that this amount could only occur in the year 80 B.C. and (because we do not know the month) at all years just 120 years (i.e., 30 days divided by 1/4 day per year) before or after that date. Alternative dates are archaeologically unlikely: 200 B.C. is too early; 40 A.D. is too late. Hence, if the slip ring has not moved from its last position, it was set in. 80 B.C. Furthermore, if we are right in supposing that a fiducial mark near the month scale was put there originally to provide a means of setting that scale in case of accidental movement, we can tell more. This mark is exactly 1/2 degree away from the present position of the scale, and this implies that the mark was made two years before the setting. Thus, although the evidence is by no means conclusive, we are led to suggest that the instrument was made about 82 B.C., used for two years (just long enough for the repairs to have been needed) and then taken onto the ship within the next 30 years.
The fragments show that the original instrument carried at least four large areas of inscription: outside the front door, inside the back door, on the plate between the two back dials and on the parapegma plates near the front dial. As I have noted, there are also inscriptions around all the dials, and furthermore each part and hole would seem to have had identifying letters so that the pieces could be put together in the correct order and position. The main inscriptions are in a sorry state and only short snatches of them can be read. To provide an idea of their condition it need only be said that in some cases a plate has completely disappeared, leaving behind an impression of its letters, standing up in a mirror image, in relief on the soft corrosion products on the plate below. It is remarkable that such inscriptions can be read at all.
But even from the evidence of a few complete words one can get an idea of the subject matter. The sun is mentioned several times, and the planet Venus once; terms are used that refer to the stations and retrogradations of planets; the ecliptic is named. Pointers, apparently those of the dials, are mentioned. A line of one inscription signfficantly records "76 years, 19 years." This refers to the well-known Calippic cycle of 76 years, which is four times the Metonic cycle of 19 years, or 235 synodic (lunar) months. The next line includes the number "223," which refers to the eclipse cycle of 223 lunar months.
Putting together the information gathered so far, it seems reasonable to suppose that the whole purpose of the Antikythera device was to mechanize just this sort of cyclical relation, which was a strong feature of ancient astronomy. Using the cycles that have been mentioned, one could easily design gearing that would operate from one dial having a wheel that revolved annually, and turn by this gearing a series of other wheels which would move pointers indicating the sidereal, synodic and draconitic months. Similar cycles were known for the planetary phenomena; in fact, this type of arithmetical theory is the central theme of Seleucid Babylonian astronomy, which was transmitted to the Hellenistic world in the last few centuries B.C. Such arithmetical schemes are quite distinct from the geometrical theory of circles and epicycles in astronomy, which seems to have been essentially Greek. The two types of theory were unified and brought to their peak in the second century A.D. by Claudius Ptolemy, whose labors marked the triumph of the new mathematical attitude toward geometrical models that still characterizes physics today.
The Antikythera mechanism must therefore be an arithmetical counterpart of the much more familiar geometrical models of the solar system which were known to Plato and Archimedes and evolved into the orrery and the planetarium. The mechanism is like. a great astronomical clock without an escapement, or like a modern analogue computer which uses mechanical parts to save tedious calculation. It is a pity that we have no way of knowing whether the device was turned automatically or by hand. It might have been held in the hand and turned by a wheel at the side so that it would operate as a computer, possibly for astrological use. I feel it is more likely that it was permanently mounted, perhaps set in a statue, and displayed as an exhibition piece. In that case it might well have been turned by the power from a water clock or some other device. Perhaps it is just such a wondrous device that was mounted inside the famous Tower of Winds in Athens. It is certainly very similar to the great astronomical cathedral clocks that were built all over Europe during the Renaissance.
It is to the prehistory of the mechanical I clock that we must look for important analogies the Antikythera mechanism and for an assessment of its significance. Unlike other mechanical devices, the clock did not evolve from the simple to the complex. The oldest clocks of which we are well informed were the most complicated. All the evidence points to the fact that the clock started as an astronomical showpiece that happened also to indicate the time. Gradually the timekeeping functions became more important and the device that showed the marvelous clockwork of the heavens became subsidiary. Behind the astronomical clocks of the 14th century there stretches an unbroken sequence of mechanical models of astronomical theory. At the head of this sequence is the Antikythera mechanism. Following it are instruments and clocklike computers known from Islam, from China and India and from the European Middle Ages. The importance of this line is very great, because it was the tradition of clock- making that preserved most of man's skill in scientific fine mechanics. During the Renaissance the scientific instrument-makers evolved from the clockmakers. Thus the Antikythera mechanism is, in a way, the venerable progenitor of all our present plethora of scientific hardware.
A significant passage in this story has to do with the astronomical computers of Islam. Preserved complete at the Museum of History of Science at Oxford is a 13th-century Islamic geared calendar-computer that has various periods built into it, so that it shows on dials the various cycles of the sun and moon. This design can be traced back, with slightly different periods but a similar arrangement of gears, to a manuscript written by the astronomer al-Biruni about 1000 A.D. Such instruments am much simpler than the Antikythera mechanism, but they show so many points of agreement in technical detail that it seems clear they came from a common tradition. The same 60-degree gear teeth are used; wheels are mounted on square-shanked axles; the geometrical layout of the gear assembly appears comparable. It was just at this time that Islam was drawing on Greek knowledge and rediscovering ancient Greek texts. It seems likely that the Antikythera tradition was part of a large corpus of knowledge that has since been lost to us but was known to the Arabs. It was developed and transmitted by them to medieval Europe, where it .became the foundation for the whole range of subsequent invention in the field of clockwork.
On the one hand the Islamic devices knit the whole story together, and demonstrate that it is through ancestry and not mere coincidence that the Antikythera mechanism resembles a modern clock. On the other hand they show that the Antikythera mechanism was no flash in the pan but was a part of an important current in Hellenistic civilization. History has contrived to keep that current dark to us, and only the accidental underwater preservation of fragments that would otherwise have crumbled to dust has now brought it to light. It is a bit frightening to know that just before the fall of their great civilization the ancient Greeks had come so close to our age, not only in their thought, but also in their scientific technology.

Rebuilding of the machine of Anticythère: it is the result of research of the pr. Derek de Solla Price, in collaboration with the National Scientific Research Center Démokritos and the physicist CH Karakalos who carried out the x-ray tomography of the original and the mechanism reconstituted to show their operation. Price built a rectangular box of 0.33 X 0.17 X 0.10 m with plates of information and protection, carrying Greek inscriptions of planets. The mechanism is a complex set of 32 gears of various sizes, turning at different speeds. The mechanism was offered by the pr. Price to the national Museum in 1980 and remains the reference for the study of the original despite the fact that its construction has been subject to much criticism. National archaeological museum, Athens, n°BE 109/1980.
An ancient piece of clockwork shows the deep roots
of modern technology
WHEN a Greek sponge diver called Elias Stadiatos discovered the wreck of a cargo ship off the tiny island of Antikythera in 1900, it was the statues lying on the seabed that made the greatest impression on him. He returned to the surface, removed his helmet, and gabbled that he had found a heap of dead, naked women. The ship's cargo of luxury goods also included jewellery, pottery, fine furniture, wine and bronzes dating back to the first century BC. But the most important finds proved to be a few green, corroded lumps—the last remnants of an elaborate mechanical device.
The Antikythera mechanism, as it is now known, was originally housed in a wooden box about the size of a shoebox, with dials on the outside and a complex assembly of bronze gear wheels within. X-ray photographs of the fragments, in which around 30 separate gears can be distinguished, led the late Derek Price, a science historian at Yale University, to conclude that the device was an astronomical computer capable of predicting the positions of the sun and moon in the zodiac on any given date. A new analysis, though, suggests that the device was cleverer than Price thought, and reinforces the evidence for his theory of an ancient Greek tradition of complex mechanical technology.
Michael Wright, the curator of mechanical engineering at the Science Museum in London, has based his new analysis on detailed X-rays of the mechanism using a technique called linear tomography. This involves moving an X-ray source, the film and the object being investigated relative to one another, so that only features in a particular plane come into focus. Analysis of the resulting images, carried out in conjunction with Allan Bromley, a computer scientist at Sydney University, found the exact position of each gear, and suggested that Price was wrong in several respects.
In some cases, says Mr Wright, Price seems to have “massaged” the number of teeth on particular gears (most of which are, admittedly, incomplete) in order to arrive at significant astronomical ratios. Price's account also, he says, displays internal contradictions, selective use of evidence and unwarranted speculation. In particular, it postulates an elaborate reversal mechanism to get some gears to turn in the right direction.
Since so little of the mechanism survives, some guesswork is unavoidable. But Mr Wright noticed a fixed boss at the centre of the mechanism's main wheel. To his instrument-maker's eye, this was suggestive of a fixed central gear around which other moving gears could rotate. This does away with the need for Price's reversal mechanism and leads to the idea that the device was specifically designed to model a particular form of “epicyclic” motion.
The Greeks believed in an earth-centric universe and accounted for celestial bodies' motions using elaborate models based on epicycles, in which each body describes a circle (the epicycle) around a point that itself moves in a circle around the earth. Mr Wright found evidence that the Antikythera mechanism would have been able to reproduce the motions of the sun and moon accurately, using an epicyclic model devised by Hipparchus, and of the planets Mercury and Venus, using an epicyclic model derived by Apollonius of Perga. (These models, which predate the mechanism, were subsequently incorporated into the work of Claudius Ptolemy in the second century AD.)
A device that just modelled the motions of the sun, moon, Mercury and Venus does not make much sense. But if an upper layer of mechanism had been built, and lost, these extra gears could have modelled the motions of the three other planets known at the time—Mars, Jupiter and Saturn. In other words, the device may have been able to predict the positions of the known celestial bodies for any given date with a respectable degree of accuracy, using bronze pointers on a circular dial with the constellations of the zodiac running round its edge.
Mr Wright devised a putative model in which the mechanisms for each celestial body stack up like layers in a sandwich, and started building it in his workshop. The completed reconstruction, details of which appeared in an article in the Horological Journal in May, went on display this week at Technopolis, a museum in Athens. By winding a knob on the side, celestial bodies can be made to advance and retreat so that their positions on any chosen date can be determined. Mr Wright says his device could have been built using ancient tools because the ancient Greeks had saws whose teeth were cut using v-shaped files—a task that is similar to the cutting of teeth on a gear wheel. He has even made several examples by hand.
How closely this reconstruction matches up to the original will never be known. The purpose of two dials on the back of the device is still unclear, although one may indicate the year. Nor is the device's purpose obvious: it may have been an astrological computer, used to speed up the casting of horoscopes, though it might just as easily have been a luxury plaything. But Mr Wright is convinced that his epicyclic interpretation is correct, and that the original device modelled the entire known solar system.
The Greeks had a word for it
That tallies with ancient sources that refer to such devices. Cicero, writing in the first century BC, mentions an instrument “recently constructed by our friend Poseidonius, which at each revolution reproduces the same motions of the sun, the moon and the five planets.” Archimedes is also said to have made a small planetarium, and two such devices were said to have been rescued from Syracuse when it fell in 212BC. This reconstruction suggests such references can now be taken literally.
It also provides strong support for Price's theory. He believed that the mechanism was strongly suggestive of an ancient Greek tradition of complex mechanical technology which, transmitted via the Arab world, formed the basis of European clockmaking techniques. This fits with another, smaller device that was acquired in 1983 by the Science Museum, which models the motions of the sun and moon. Dating from the sixth century AD, it provides a previously missing link between the Antikythera mechanism and later Islamic calendar computers, such as the 13th century example at the Museum of the History of Science in Oxford. That device, in turn, uses techniques described in a manuscript written by al-Biruni, an Arab astronomer, around 1000AD.
The origins of much modern technology, from railway engines to robots, can be traced back to the elaborate mechanical toys, or automata, that flourished in the 18th century. Those toys, in turn, grew out of the craft of clockmaking. And that craft, like so many other aspects of the modern world, seems to have roots that can be traced right back to ancient Greece.

The recent discovery
....updated below is the latest discovery..... 12/27/06..... concerning this device. The Earth-Moon relationship only uses 8 or 9 gears to show the relationship between Earth and lunar orbits. After studying some of the other gear rotation angles I chanced upon this very crucial discovery concerning the planet Venus. The tropical year for Venus is 224.70069 Earth days for one orbit.(Wikipedia) If you rotate this circumference 360 degrees along the Earth orbit number 365.246742 days ...Venus/Earth.... and multiply by the Sun Gear(64) you get the value for m used in the article below:
Venus orbit / Earth orbit * Sun gear / ( 10^3 ) = .0393700787 = m
224.6842679 / 365.246742 * 64 / ( 10 ^ 3 ) = .0393700787 = m
224.6842679 / 365.246742 * 64 / ( 10 ^ 3 ) = .0393700787 = m
......the Venus orbit is m's source ??!!

one meter = 39.3700787 inches
John Wilkins invents the meterI'm continuing to read An Essay Towards a Real Character and a Philosophical Language, the Right Reverend John Wilkins' 1668 book that attempted to lay out a rational universal language.
In skimming over it, I noticed that Wilkins' language contained words for units of measure: "line", "inch", "foot", "standard", "pearch", "furlong", "mile", "league", and "degree". I thought oh, this was another example of a foolish Englishman mistaking his own provincial notions for universals. Wilkins' language has words for Judaism, Christianity, Islam; everything else is under the category of paganism and false gods, and I thought that the introduction of words for inches and feet was another case like that one. But when I read the details, I realized that Wilkins had been smarter than that.
Wilkins recognizes that what is needed is a truly universal measurement standard. He discusses a number of ways of doing this and rejects them. One of these is the idea of basing the standard on the circumference of the earth, but he thinks this is too difficult and inconvenient to be practical.
But he settles on a method that he says was suggested by Christopher Wren, which is to base the length standard on the time standard (as is done today) and let the standard length be the length of a pendulum with a known period. Pendulums are extremely reliable time standards, and their period depends only their length and on the local effect of gravity. Gravity varies only a very little bit over the surface of the earth. So it was a reasonable thing to try.
Wilkins directed that a pendulum be set up with the heaviest, densest possible spherical bob at the end of lightest, most flexible possible cord, and the the length of the cord be adjusted until the period of the pendulum was as close to one second as possible. So far so good. But here is where I am stumped. Wilkins did not simply take the standard length as the length from the fulcrum to the center of the bob. Instead:...which being done, there are given these two Lengths, viz. of the String, and of the Radius of the Ball, to which a third Proportional must be found out; which must be as the length of the String from the point of Suspension to the Centre of the Ball is to the Radius of the Ball, so must the said Radius be to this third which being so found, let two fifths of this third Proportional be set off from the Centre downwards, and that will give the Measure desired.
Wilkins is saying, effectively: let d be the distance from the point of suspension to the center of the bob, and r be the radius of the bob, and let x by such that d/r = r/x. Then d+(0.4)x is the standard unit of measurement.Huh? Why 0.4? Why does r come into it? Why not just use d? Huh?
These guys weren't stupid, and there must be something going on here that I don't understand. Can any of the physics experts out there help me figure out what is going on here?
Anyway, the main point of this note is to point out an extraordinary coincidence. Wilkins says that if you follow his instructions above, the standard unit of measurement "will prove to be . . . 39 Inches and a quarter". In other words, almost exactly one meter.
I bet someone out there is thinking that this explains the oddity of the 0.4 and the other stuff I don't understand: Wilkins was adjusting his definition to make his standard unit come out to exactly one meter, just as we do today. (The modern meter is defined as the distance traveled by light in 1/299,792,458 of a second. Why 299,792,458? Because that's how long it happens to take light to travel one meter.) But no, that isn't it. Remember, Wilkins is writing this in 1668. The meter wasn't invented for another 110 years.
Having defined the meter, which he called the "Standard", Wilkins then went on to define smaller and larger units, each differing from the standard by a factor that was a power of 10. So when Wilkins puts words for "inch" and "foot" into his universal language, he isn't putting in words for the common inch and foot, but rather the units that are respectively 1/100 and 1/10 the size of the Standard. His "inch" is actually a centimeter, and his "mile" is a kilometer, to within a fraction of a percent.Wilkins also defined units of volume and weight measure. A cubic Standard was called a "bushel", and he had a "quart" (1/100 bushel, approximately 10 liters) and a "pint" (approximately one liter). For weight he defined the "hundred" as the weight of a bushel of distilled rainwater; this almost precisely the same as the original definition of the gram. A "pound" is then 1/100 hundred, or about ten kilograms. I don't understand why Wilkins' names are all off by a factor of ten; you'd think he would have wanted to make the quart be a millibushel, which would have been very close to a common quart, and the pound be the weight of a cubic foot of water (about a kilogram) instead of ten cubic feet of water (ten kilograms). But I've read this section over several times, and I'm pretty sure I didn't misunderstand.
Wilkins also based a decimal currency on his units of volume: a "talent" of gold or silver was a cubic standard. Talents were then divided by tens into hundreds, pounds, angels, shillings, pennies, and farthings. A silver penny was therefore 10-5 cubic Standard of silver. Once again, his scale seems off. A cubic Standard of silver weighs about 10.4 metric tonnes. Wilkins' silver penny is about is nearly ten cubic centimeters of metal, weighing 104 grams (about 3.5 troy ounces), and his farthing is 10.4 grams. A gold penny is about 191 grams, or more than six ounces of gold. For all its flaws, however, this is the earliest proposal I am aware of for a fully decimal system of weights and measures, predating the metric system, as I said, by about 110 years.
More about calculator
....at the last website is the complete schematic breakdown of the device , shown in five gear colors , blue , yellow-sun gear , green , orange , purple and dark green. Thirty gear numbers are shown , each having one of the above colors. The key number constant used in all thirty gears is the modern metric to english conversion constant ...( 39.3700787 inches = 1 meter )... rewritten to this form :
39.3700787 / ( 10 ^ 3 ) = m = 1/25.4
....all thirty gears are linked and can be turned all at once by the rotation of any one gear in the system . I chose the blue(50) gear as a starting point and turned this gear exactly one-revolution or 360 degrees. The gematric formula for this angle is the sacred number 72 , times one half the metric standard 254 ( 254/2 = 127 ):
72 * 127 * m = 360 degrees
....this angle is transferred to the second blue(50) gear because of its being self similar to the first blue(50) gear. This angle is also transferred to the blue(32) gear because of a shared axle. The next step is the blue(32) gear's link to gear , blue(127) .
This link is the famous sacred Alautun time cycle number ...2304...from Aztec and Mayan culture. Here is a link with the explanation of the number:....this is very important to the explanation of the Antikythera device because both the 1152 and 2304 units are Mayan calendar constants measured in DAYS !! the same as the Antikythera mechanism !!20 calabtun = 1 kinchiltin = a cycle of 11520000000 days
20 kinchiltin = 1 alautun = a cycle of 23040000000 days...so I would say that 1152 ( kinchiltin ) is a thing of Mayan origin as is the 2304 (alautun ) number.
blue(127) = 2304 * m = 32 / 127 * 360 = 90.70866132 degrees
blue(24) = 2304 * m = 32 / 127 * 360 = 90.70866132 degrees
blue(24) = 2304 * m = 32 / 127 * 360 = 90.70866132 degrees
...that is when you turn the starter blue(50) gear 360 degrees, the blue(127) gear will turn 90.70866132 degrees. The blue(24) gear shares an axle with the blue(127) gear and thus shares the rotation of the blue(127) gear. Blue(24) gear then transfers this rotation to the blue(48) gear . This angle of rotation is the gematric number known as the Egyptian foot number ..1152...:
blue(38) = 1152 * m = 32/127*24/48*360 = 45.35433066 degrees
blue(48) = 1152 * m = 32/127*24/48*360 = 45.35433066 degrees
blue(48) = 1152 * m = 32/127*24/48*360 = 45.35433066 degrees
...blue(38) shares an axle with blue(48) and thus transfers this angle of rotation to the so-called Sun gear... yellow(64)..The number 19 appears here not as years of the Metonic cycle but as DAYS!! on the edge of gear wheels:
Sun gear = 36 * 19 * m = 32/127*24/48*38/64*360 = 26.92913383 degrees
....all of the green gears share the same angle of rotation as the Sun gear. The orange gears appear when the second gear with 38 cogs appears as orange(38). It has the same angle of rotation as the blue(38) gear:
orange(38) = 1152 * m = 32/127*24/48*360 = 45.3543306 degrees
orange(53) = 1152 * m = 32/127*24/48*360 = 45.3543306 degrees
orange(53) = 1152 * m = 32/127*24/48*360 = 45.3543306 degrees
...orange(53) shares an axle with orange(38) and thus transfers this angle of rotation to orange(96)
orange(96) = 25 + m = 53*12 * m = 32/127*24/48*53/96*360 = 25.0393700787 degrees
...orange(15) and orange(27) gears share axles with orange(96) and thus transfers angular rotation to the large gear purple(223):
purple(223) = 53*12*27*m/223 = 36*m+360/223 = 32/127*24/48*53/96*27/223*360 degrees
..purple(53) edges with purple(223) thus picking up an angular rotation of:
purple(53) = 54 * 6 * m = 32/127*24/48*27/96*360 = 12.7559055 degrees
purple(30) = 54 * 6 * m = 32/127*24/48*27/96*360 = 12.7559055 degrees
purple(30) = 54 * 6 * m = 32/127*24/48*27/96*360 = 12.7559055 degrees
...purple(30) shares an axle with purple(53) and thus the same rotation. Purple(30) edges with purple(54) resulting in an angle turn of 7.086614166 degrees for purple(54):
purple(54) = 180 * m = 7.086614166 degrees
...three other gears share this angle of rotation and thus the same axle, purple(20) , dk green(53) , dk green(15). dk green(15) transfers the angle to gear dk green(60) and gear dk green(12) which shares an axle with dk green(60):
dk green(60) = 180 / 4 * m = 32/127*24/48*15/96*15/60*360 = 1.771653542 degrees
dk green(12) = 180 / 4 * m = 32/127*24/48*15/96*15/60*360 = 1.771653542 degrees
dk green(12) = 180 / 4 * m = 32/127*24/48*15/96*15/60*360 = 1.771653542 degrees
...dk green(12) transfers the angle of rotation to the last gear in the chain, dk green(60)
dk green(60) = 9 * m = 32/127*24/48*15/96*15/60*12/60*360 = .354330708 degrees

...how does this data relate to the earth-moon interaction? One can observe that the last gear in the chain of 360 degree rotation , blue(32)...if one makes this gear analogous to the moon lunar cycle...29.530588 days in one orbit around earth , then blue (32) and the lunar cycle share an axle that rotates 360 degrees. Transferring this 360 degree rotation of the lunar cycle to the earth cycle around the sun...365.246743 days in one tropical year , on this earth cycle axle , place the 5 sets of 47 (235) markings of the exterior dials of the device on the earth axis of rotation and multiply by the metric m :
29.530588 / 365.2467463 * 5 * 47 *m * 36 = 26.92913386 degrees = 19 * 36 * m = sun gear(64)
29.530588 / 365.2467463 * 235 / 254 = 26.92913386 degrees = 19 * 36 * m = sun gear(64)
29.530588 / 365.2467463 * 235 / 254 = 26.92913386 degrees = 19 * 36 * m = sun gear(64)
...this is exactly the angle turned by the sun gear when the blue(50) gear is rotated once!! Checking the number constants I wanted to see if the number 37 is any where in the angles of rotation or in the gear numbers. Strangely it sits at the heart of the Earth/Moon link. When the lunar cycle 29.530588 days is rotated once (360 degrees) on the Earth cycle .365.246743 days... an angle of rotation is generated on the Earth cycle rim:
29.530588 / 365.246743 * 360 = degrees of rotation of Earth orbit disc = 29.10638332
....37 derives this angle through the 47 markings on the outside dials of the device:

Vymaanika-Shaastra
Uma vimāna é um veículo voador mitológico, descrito na literatura antiga da Índia.
Referências a veículos voadores são comuns nos textos antigos indianos, que, inclusive, descrevem seus usos na arte da guerra. Independentemente de serem capazes de voar na atmosfera terrestre, consta que as vimānas também viajam pelo espaço e sob a água. Descrições contidas nos Vedas e na literatura indiana recente falam de vimānas de várias formas e tamanhos:
- Nos Vedas: o sol e várias outras divindades são levadas em suas peregrinações por carruagens voadoras, com rodas, puxadas por animais, geralmente cavalos (já a carruagem do deus védico Puchan é puxada por bodes)
- O "agnihotra-vimāna", com dois motores (?). (Agni significa fogo em sânscrito).
- O "gaja-vimāna", com mais motores (?) (Gaja significa elefante em sânscrito).
- Outros tipos, com denominações baseadas em animais, como o martim-pescador, o Íbis, e outros animais.
Alguns ufólogos modernos atribuem às vimāna evidências de civilizações tecnologicamente avançadas do passado, e da Teoria dos astronautas antigos. Outros estabeleceram ligações das máquinas voadoras com a lenda dos Nove Homens Desconhecidos. David Hatcher Childress fala sobre elas em seu livro "Vimana Aircraft of Ancient India & Atlantis"(Vimana - Aeronáutica da Índia Antiga e da Atlântida),citando também alguns de seus livros anteriores, como "Lost Cities of China, Central Asia & India"(Cidades Perdidas da China, Índia e Ásia Central).
[editar] Etimologia e uso
A palavra origina-se do sânscrito e parece ser vi-māna = "separado — mensurado". O significado da palavra parece ter sido modificado nesta sequência:
- Uma área de terra medida e separada para ser usada para fins sagrados.
- Templo.
- O palácio de um deus.
- Em escritos indianos recentes: outros veículos voadores, e às vezes vimāna é usada como um termo poético para fazer referência a veículos comuns terrestres.
[editar] Outros significados
- Na maioria das línguas indianas modernas, a palavra vimāna significa uma aeronave comum, real.
- O livro budista Vimānavatthu (Histórias de Vimanas, em Pali) usa a palavra "vimāna" com um significado diferente: "um pequeno trecho de um texto usado como inspiração para um sermão budista".
Ancient Flying Machines
Introduction
Flight has been the dream of humankind since they watched in awe as birds soared effortlessly through the sky. But, according to accepted history, it wasn't until the 1780s that two Frenchmen achieved lighter-than-air flight when they were lifted into the air in a hot air balloon near Paris. Then powered, heavier-than-air flight became the goal. And although it was theorized that heavier-than-air flight was possible as early as the 13th century, and in the 16th century Leonardo da Vinci designed winged aircraft and a crude kind of helicopter, it wasn't until the Wright brothers made their first successful flights at Kitty Hawk in 1903 that powered flight became a reality.
That's the widely accepted history. Some researchers and a few rogue scientists believe there's evidence to suggest that humans achieved flight earlier in history - much earlier... so early, they say, that the knowledge of this technology has been lost and ancient stories that recount adventures of human flight have been relegated only to myth.
Is it possible that humans developed the technology to fly in early civilizations - or in civilizations that are now lost to history? Let's take a look at what some call the evidence - intriguing artifacts, carvings, inscriptions and legends - that they say point to the true record human of flight.
Airplane Models

This object (shown in sketch) was found in 1898 in a tomb at Saqquara, Egypt and was later dated as having been created near 200 BCE. As airplanes were unknown in the days when it was found, it was thrown into a box marked "wooden bird model" and then stored in the basement of the Cairo museum.
| As a result of their findings, a special exhibit was set up in the center hall of the Cairo museum, with the little model as its centerpiece. It was even labelled as a model airplane. |
To elucidate the reasons for the decision of the committee, almost unprecedented in the field of archeology, let's consider some aspects of the model. The model has the exact proportions of a very advanced form of "pusher-glider" that is still having "some bugs ironed out". This type of glider will stay in the air almost by itself—even a very small engine will keep it going at low speeds, as low as 45 to 65 mph., while it can carry an enormous payload. This ability is dependent on the curious shape of wings and their proportions. The tipping of wings downward, a reversedihedral wing as it is called, is the feature behind this capability. A similar type of curving wings are implemented on the Concorde airplane, giving the plane a maximum lift without detracting from its speed.
In that context, it seems rather incredible that someone, more than 2,000 years ago, for any reason, devised a model of a flying device with such advanced features, requiring quite extensive knowledge of aerodynamics. There were no such things as airplanes in these times, we are told by archeologists and historians. But this case seems to be an exception, living in the midst of the rather unimaginative and rigid paradigm of contemporary science. It is also necessary to point out that Egyptians are known to have nearly always made scale-models of projects and objects which they planned to create or build.
Precolombian Airplane Models
Is the concept of an airplane limited to Egypt? That doesn't seem to be the case. Gold trinkets were found in an area covering Central America and coastal areas of South America, estimated to belong to a period between 500 and 800 CE, but since they are made from gold, accurate dating is impossible and based essentially on stratigraphy which may be deceptive. However, we can safely say that these gold objects are more than 1000 years old.
Whatever this object is supposed to be or represent,
its remarkable resemblance to a modern aircraft or spacecraft is uncanny.
its remarkable resemblance to a modern aircraft or spacecraft is uncanny.
There are several types of animals which fly—birds, insects, and several mammals, such as bats and some gliders, for instance flying squirrels, oppossums, and then there are some lizards; there are also some fish which for brief periods glide through the air. There are water animals which seem to fly through the water, such as rays, skates and some selachians. But how does the depicted object compare with these choices? All its features taken into a consideration, we have no match. Seen from above, the object obviously has no fish features, but seems to show rather explicitly mechanistic ones.
When all the features are taken into an account, the object does not look like a representation of any known animal at all, but does look astonishingly like an airplane. The photos and enlarged outline of the object has been submitted for an analysis to several people from the field of aerodynamics. One of them was Arthur Young, a designer of Bell helicopters and other aircraft. His analysis confirmed that the object contains many features which would fit the airplane hypothesis, but there were several ones which would not fit that scenario. Wings do seem to be in the wrong place—they should be further forward so that their 1/4-chord coincides with the center of gravity. The nose is not like anything on airplanes, as well. So, while the object is suggesting an airplane, some features would not seem to support this hypothesis.
All things considered, the object seems to represent a convertible type of craft, with two possible configurations—one for ascent when the nose is facing backwards, and the other for descent with the nose facing forward. One unsolved item remains—the spirals on the both wings and the nose. According to Amerindian iconography, these spirals have discernable meaning—they represent ascending and descending, depending on whether they are right-oriented or left-oriented, respectively. As the spirals are not only on wings but also on the nose, the meaning is fairly obvious—the wings and the nose (as much) were the features which were directly involved in ascent and descent.
There are other cultures which mention flying vehicles of some sort or another. The most known of these sources are Indian epics, especially the Mahábhárata and other Védic sources as Bhágavata Purána and Rámáyana. The flying devices were called vimánas and were extensively discussed in Vaimánika Shástra, describing multitude of machines with different purposes and capabilities.
Other source of information about flying machines may be considered, such as the Bible and some apocryphal works. The book of Ezekiel seems to be describing the close encounter of a man from a non-technological culture with a device which to him must have been miraculous. We have to put ourselves into his shoes to comprehend his astonishment and the otherworldness of his encounter. The limited scope of knowledge of the world around him, his primitive environment, dictated the language and conceptual framework with which he tried to capture his encounter for fellow tribesmen. For him it seemed that he encountered The God, with his suite of angels, because in his simple world, there was no other interpretation. It is not necessary to reach for an alien type of scenario to explain the encounter; we can entertain a possibility that a remnant of an advanced civilization was still present, in a limited scope, at the time of Ezekiel. But for some, the encounter bears uncanny similarity to the modern-day encounters with UFO's. Another source of similar material is the Book of Enoch, particularly the Slavic version, which contains some parts which the Greek version is missing. The book not only describes flying in the air, but also through outer space, including the relativistic effects mentioned—Enoch spent several days on a spacecraft, but when he returned to Earth, several centuries had passed by.
There is no shortage of descriptions of flying machines in ancient sources. If we try to extract the core of myths of different provenience and remove the embellishments, we discover to our surprise that flying in ancient times seems to be the rule, not the exception.

Ancient Indian Aircraft Technology

Many researchers into the UFO enigma tend to overlook a very important fact. While it assumed that most flying saucers are of alien, or perhaps Governmental Military origin, another possible origin of UFOs is ancient India and Atlantis.
What we know about ancient Indian flying vehicles comes from ancient Indian sources; written texts that have come down to us through the centuries. There is no doubt that most of these texts are authentic; many are the well known ancient Indian Epics themselves, and there are literally hundreds of them. Most of them have not even been translated into English yet from the old Sanskrit.
The Indian Emperor Ashoka started a "Secret Society of the Nine Unknown Men": great Indian scientists who were supposed to catalogue the many sciences. Ashoka kept their work secret because he was afraid that the advanced science catalogued by these men, culled from ancient Indian sources, would be used for the evil purpose of war, which Ashoka was strongly against, having been converted to Buddhism after defeating a rival army in a bloody battle.
The "Nine Unknown Men" wrote a total of nine books, presumably one each. Book number was "The Secrets of Gravitation!" This book, known to historians, but not actually seen by them dealt chiefly with "gravity control." It is presumably still around somewhere, kept in a secret library in India, Tibet or elsewhere (perhaps even in North America somewhere). One can certainly understand Ashoka's reasoning for wanting to keep such knowledge a secret, assuming it exists. if the Nazis had such weapons at their disposal during World War Ii. Ashoka was also aware devastating wars using such advanced vehicles and other "futuristic weapons" that had destroyed the ancient Indian "Rama Empire" several thousand years before.
Only a few years ago, the Chinese discovered some Sanskrit documents in Lhasa, Tibet and sent them to the University of Chandrigarh to be translated. Dr. Ruth Reyna of the University said recently that the documents contain directions for building interstellar spaceships!
Their method of propulsion, she said, was "anti-gravitational" and was based upon a system analogous to that of "laghima," the unknown power of the ego existing in man's physiological makeup, "a centrifugal force strong enough to counteract all gravitational pull." According to Hindu Yogis, it is this "laghima" which enables a person to levitate.
Dr. Reyna said that on board these machines, which were called "Astras" by the text, the ancient Indians could have sent a detachment of men onto any planet, according to the document, which is thought to be thousands of years old. The manuscripts were also said to reveal the secret of "antima"; "the cap of invisibility" and "garima"; "how to become as heavy as a mountain of lead."
Naturally, Indian scientists did not take the texts very seriously, but then became more positive about the value of them when the Chinese announced that they were including certain parts of the data for study in their space program! This was one of the first instances of a government admitting to be researching anti-gravity.
The manuscripts did not say definitely that interplanetary travel was ever made but did mention, of all things, a planned trip to the Moon, though it is not clear whether this trip was actually carried out. However, one of the great Indian epics, the Ramayana, does have a highly detailed story in it of a trip to the moon in a Vimana (or "Astra"), and in fact details a battle on the moon with an "Asvin" (or Atlantean" airship.
This is but a small bit of recent evidence of anti-gravity and aerospace technology used by Indians. To really understand the technology, we must go much further back in time.
The so-called "Rama Empire" of Northern India and Pakistan developed at least fifteen thousand years ago on the Indian sub-continent and was a nation of many large, sophisticated cities, many of which are still to be found in the deserts of Pakistan, northern, and western India. Rama existed, apparently, parallel to the Atlantean civilization in the mid-Atlantic Ocean, and was ruled by "enlightened Priest-Kings" who governed the cities, The seven greatest capital cities of Rama were known in classical Hindu texts as "The Seven Rishi Cities."
According to ancient Indian texts, the people had flying machines which were called "Vimanas." The ancient Indian epic describes a Vimana as a double-deck, circular aircraft with portholes and a dome, much as we would imagine a flying saucer.
It flew with the "speed of the wind" and gave forth a "melodious sound." There were at least four different types of Vimanas; some saucer shaped, others like long cylinders ("cigar shaped airships"). The ancient Indian texts on Vimanas are so numerous, it would take volumes to relate what they had to say. The ancient Indians, who manufactured these ships themselves, wrote entire flight manuals on the control of the various types of Vimanas, many of which are still in existence, and some have even been translated into English.
The Samara Sutradhara is a scientific treatise dealing with every possible angle of air travel in a Vimana. There are 230 stanzas dealing with the construction, take-off, cruising for thousand of miles, normal and forced landings, and even possible collisions with birds. In 1875, the Vaimanika Sastra, a fourth century B.C. text written by Bharadvajy the Wise, using even older texts as his source, was rediscovered in a temple in India. It dealt with the operation of Vimanas and included information on the steering, precautions for long flights, protection of the airships from storms and lightening and how to switch the drive to "solar energy" from a free energy source which sounds like "anti-gravity."
The Vaimanika Sastra (or Vymaanika-Shaastra) has eight chapters with diagrams, describing three types of aircraft, including apparatuses that could neither catch on fire nor break. It also mentions 31 essential parts of these vehicles and 16 materials from which they are constructed, which absorb light and heat; for which reason they were considered suitable for the construction of Vimanas. This document has been translated into English and is available by writing the publisher: VYMAANIDASHAASTRA AERONAUTICS by Maharishi Bharadwaaja, translated into English and edited, printed and published by Mr. G. R. Josyer, Mysore, India, 1979 (sorry, no street address). Mr. Josyer is the director of the International Academy of Sanskrit Investigation located in Mysore.

There seems to be no doubt that Vimanas were powered by some sort of "anti-gravity." Vimanas took off vertically, and were capable of hovering in the sky, like a modern helicopter or dirigible. Bharadvajy the Wise refers to no less than 70 authorities and 10 experts of air travel in antiquity. These sources are now lost.
Vimanas were kept in a Vimana Griha, a kind of hanger, and were sometimes said to be propelled by a yellowish-white liquid, and sometimes by some sort of mercury compound, though writers seem confused in this matter. It is most likely that the later writers on Vimanas, wrote as observers and from earlier texts, and were understandably confused on the principle of their propulsion. The "yellowish-white liquid" sounds suspiciously like gasoline, and perhaps Vimanas had a number of different propulsion sources, including combustion engines and even "pulse-jet" engines. It is interesting to note, that the Nazis developed the first practical pulse-jet engines for their V-8 rocket "buzz bombs." Hitler and the Nazi staff were exceptionally interested in ancient India and Tibet and sent expeditions to both these places yearly, starting in the 30's, in order to gather esoteric evidence that they did so, and perhaps it was from these people that the Nazis gained some of their scientific information!
According to the Dronaparva, part of the Mahabarata, and the Ramayana, one Vimana described was shaped like a sphere and born along at great speed on a mighty wind generated by mercury. It moved like a UFO, going up, down, backwards and forewards as the pilot desired. In another Indian source, the Samar, Vimanas were "iron machines, well-knit and smooth, with a charge of mercury that shot out of the back in the form of a roaring flame." Another work called the Samaranganasutradhara describes how the vehicles were constructed. It is possible that mercury did have something to do with the propulsion, or more possibly, with the guidance system. Curiously, Soviet scientists have discovered what they call "age-old instruments used in navigating cosmic vehicles" in caves in Turkestan and the Gobi Desert. The "devices" are hemispherical objects of glass or porcelain, ending in a cone with a drop of mercury inside.
It is evident that ancient Indians flew around in these vehicles, all over Asia, to Atlantis presumably; and even, apparently, to South America. Writing found at Mohenjodaro in Pakistan (presumed to be one of the "Seven Rishi Cities of the Rama Empire") and still undeciphered, has also been found in one other place in the world: Easter Island! Writing on Easter Island, called Rongo-Rongo writing, is also undeciphered, and is uncannily similar to the Mohenjodaro script. Was Easter Island an air base for the Rama Empire's Vimana route? (At the Mohenjo-Daro Vimana-drome, as the passenger walks down the concourse, he hears the sweet, melodic sound of the announcer over the loudspeaker,
"Rama Airways flight number seven for Bali, Easter Island, Nazca, and Atlantis is now ready for boarding. Passengers please proceed to gate number..") in Tibet, no small distance, and speaks of the "fiery chariot" thusly: "Bhima flew along in his car, resplendent as the sun and loud as thunder... The flying chariot shone like a flame in the night sky of summer ... it swept by like a comet... It was as if two suns were shining. Then the chariot rose up and all the heaven brightened."
In the Mahavira of Bhavabhuti, a Jain text of the eighth century culled from older texts and traditions, we read:
"An aerial chariot, the Pushpaka, conveys many people to the capital of Ayodhya. The sky is full of stupendous flying-machines, dark as night, but picked out by lights with a yellowish glare"
The Vedas, ancient Hindu poems, thought to be the oldest of all the Indian texts, describe Vimanas of various shapes and sizes: the "ahnihotra-vimana" with two engines, the "elephant-vimana" with more engines, and other types named after the kingfisher, ibis and other animals.
Unfortunately, Vimanas, like most scientific discoveries, were ultimately used for war. Atlanteans used their flying machines, "Vailixi," a similar type of aircraft, to literally try and subjugate the world, it would seem, if Indian texts are to be believed. The Atlanteans, known as "Asvins" in the Indian writings, were apparently even more advanced technologically than the Indians, and certainly of a more war-like temperment. Although no ancient texts on Atlantean Vailixi are known to exist, some information has come down through esoteric, "occult" sources which describe their flying machines. Similar, if not identical to Vimanas, Vailixi were generally "cigar shaped" and had the capability of maneuvering underwater as well as in the atmosphere or even outer space. Other vehicles, like Vimanas, were saucer shaped, and could apparently also be submerged.
According to Eklal Kueshana, author of "The Ultimate Frontier," in an article he wrote in 1966, Vailixi were first developed in Atlantis 20,000 years ago, and the most common ones are "saucer-shaped of generally trapezoidal cross-section with three hemispherical engine pods on the underside." "They use a mechanical antigravity device driven by engines developing approximately 80,000 horse power."
The Ramayana, Mahabarata and other texts speak of the hideous war that took place, some ten or twelve thousand years ago between Atlantis and Rama using weapons of destruction that could not be imagined by readers until the second half of this century.
The ancient Mahabharata, one of the sources on Vimanas, goes on to tell the awesome destructiveness of the war:
"...(the weapon was) a single projectile
charged with all the power of the Universe.
An incandescent column of smoke and flame
As bright as the thousand suns rose in all its splendor...
charged with all the power of the Universe.
An incandescent column of smoke and flame
As bright as the thousand suns rose in all its splendor...
An iron thunderbolt,
A gigantic messenger of death,
Which reduced to ashes
The entire race of the Vrishnis
And the Andhakas.
A gigantic messenger of death,
Which reduced to ashes
The entire race of the Vrishnis
And the Andhakas.
... the corpses were so burned
As to be unrecognizable.
The hair and nails fell out;
Pottery broke without apparent cause,
And the birds turned white.
As to be unrecognizable.
The hair and nails fell out;
Pottery broke without apparent cause,
And the birds turned white.
... After a few hours
All foodstuffs were infected...
... to escape from this fire
The soldiers threw themselves in streams
To wash themselves and their equipment..."
All foodstuffs were infected...
... to escape from this fire
The soldiers threw themselves in streams
To wash themselves and their equipment..."
It would seem that the Mahabharata is describing an atomic war! References like this one are not isolated; but battles, using a fantastic array of weapons and aerial vehicles are common in all the epic Indian books. One even describes a Vimana-Vailix battle on the Moon! The above section very accurately describes what an atomic explosion would look like and the effects of the radioactivity on the population. Jumping into water is the only respite.
When the Rishi City of Mohenjodaro was excavated by archeologists in the last century, they found skeletons just lying in the streets, some of them holding hands, as if some great doom had suddenly overtaken them. These skeletons are among the most radioactive ever found, on a par with those found at Hiroshima and Nagasaki. Ancient cities whose brick and stone walls have literally been vitrified, that is-fused together, can be found in India, Ireland, Scotland, France, Turkey and other places. There is no logical explanation for the vitrification of stone forts and cities, except from an atomic blast. Furthermore, at Mohenjo-Daro, a well planned city laid on a grid, with a plumbing system superior to those used in Pakistan and India today, the streets were littered with "black lumps of glass." These globs of glass were discovered to be clay pots that had melted under intense heat!
With the cataclysmic sinking of Atlantis and the wiping out of Rama with atomic weapons, the world collapsed into a "stone age" of sorts, and modern history picks up a few thousand years later. Yet, it would seem that not all the Vimanas and Vailixi of Rama and Atlantis were gone. Built to last for thousands of of years, many of them would still be in use, as evidenced by Ashoka's "Nine Unknown Men" and the Lhasa manuscript.
That secret societies or "Brotherhoods" of exceptional, "enlightened" human beings would have preserved these inventions and the knowledge of science, history, etc., does not seem surprising. Many well known historical personages including Jesus, Buddha, Lao Tzu, Confucius, Krishna, Zoroaster, Mahavira, Quetzalcoatl, Akhenaton, Moses, and more recent inventors and of course many other people who will probably remain anonymous, were probably members of such a secret organization.
It is interesting to note that when Alexander the Great invaded India more than two thousand years ago, his historians chronicled that at one point they were attacked by "flying, fiery shields" that dove at his army and frightened the cavalry. These "flying saucers" did not use any atomic bombs or beam weapons on Alexander's army however, perhaps out of benevolence, and Alexander went on to conquer India.
It has been suggested by many writers that these "Brotherhoods" keep some of their Vimanas and Vailixi in secret caverns in Tibet or some other place is Central Asia, and the Lop Nor Desert in western China is known to be the center of a great UFO mystery. Perhaps it is here that many of the airships are still kept, in underground bases much as the Americans, British and Soviets have built around the world in the past few decades.
Still, not all UFO activity can be accounted for by old Vimanas making trips to the Moon for some reason. Undoubtedly, some are from the Military Governments of the world, and possibly even from other planets. Of course, many UFO sightings are "swamp, gas, clouds, hoaxes, and hallucinations, while there is considerable evidence that many UFO sightings, especially "kidnappings" and the like, are the result of what is generally called "telepathic hypnosis." One common thread that often runs between "Alien kidnappings," "sex with aliens," and other "close encounters of a third kind" is a buzzing in the ears just before the encounter. According to many well informed people, this is a sure sign of telepathic hypnosis."

ANCIENT VIMANA AIRCRAFT
SOURCE: John Burrows
Sanskrit texts are filled with references to gods who fought battles in the sky using Vimanas equipped with weapons as deadly as any we can deploy in these more enlightened times. For example, there is a passage in the Ramayana which reads:
"The Puspaka car that resembles the Sun and belongs to my brother was brought by the powerful Ravan; that aerial and excellent car going everywhere at will .... that car resembling a bright cloud in the sky."
".. and the King [Rama] got in, and the excellent car at the command of the Raghira, rose up into the higher atmosphere."
In the Mahabharatra, an ancient Indian poem of enormous length, we learn that an individual named Asura Maya had a Vimana measuring twelve cubits in circumference, with four strong wheels. The poem is a veritable gold mine of information relating to conflicts between gods who settled their differences apparently using weapons as lethal as the ones we are capable of deploying. Apart from 'blazing missiles', the poem records the use of other deadly weapons. 'Indra's Dart' operated via a circular 'reflector'. When switched on, it produced a 'shaft of light' which, when focused on any target, immediately 'consumed it with its power'. In one particular exchange, the hero, Krishna, is pursuing his enemy, Salva, in the sky, when Salva's Vimana, the Saubha is made invisible in some way. Undeterred, Krishna immediately fires off a special weapon: 'I quickly laid on an arrow, which killed by seeking out sound'. Many other terrible weapons are described, quite matter of factly, in the Mahabharata, but the most fearsome of all is the one used against the Vrishis. The narrative records:
"Gurkha flying in his swift and powerful Vimana hurled against the three cities of the Vrishis and Andhakas a single projectile charged with all the power of the Universe. An incandescent column of smoke and fire, as brilliant as ten thousands suns, rose in all its splendour. It was the unknown weapon, the Iron Thunderbolt, a gigantic messaenger of death which reduced to ashes the entire race of the Vrishnis and Andhakas."
It is important to note, that these kinds of records are not isolated. They can be cross-correlated with similiar reports in other ancient civilizations. The after-affects of this Iron Thunderbolt have an ominously recognizable ring. Apparently, those killed by it were so burnt that their corpses were unidentifiable. The survivors fared little etter, as it caused their hair and nails to fall out.
Perhaps the most disturbing and challenging, information about these allegedly mythical Vimanas in the ancient records is that there are some matter-of-fact records, describing how to build one. In their way, the instructions are quite precise.
In the Sanskrit Samarangana Sutradhara, it is written:
"Strong and durable must the body of the Vimana be made, like a great flying bird of light material. Inside one must put the mercury engine with its iron heating apparatus underneath. By means of the power latent in the mecrcury which sets the driving whirlwind in motion, a man sitting inside may travel a great distance in the sky. The movements of the Vimana are such that it can vertically ascend, vertically descend, move slanting forwards and backwards. With the help of the machines human beings can fly in the air and heavenly beings can come down to earth."
The Hakatha (Laws of the Babylonians) states quite unambiguously: "The privilege of operating a flying machine is great. The knowledge of flight is among the most ancient of our inheritances. A gift from 'those from upon high'. We received it from them as a means of saving many lives."
More fantastic still is the information given in the ancient Chaldean work, The Sifrala, which contains over one hundred pages of technical details on building a flying machine. It contains words which translate as graphite rod, copper coils, crystal indicator, vibrating spheres, stable angles, etc.
Flying high
Hundred years after Orville Wright’s first flight, K R N SWAMY remembers Shivkur Bapuji Talpade, the Indian who flew an unmanned aircraft, eight years before Wright.
Orville Wright demonstrated on December 17th 1903 that it was possible for a ‘manned heavier than air machine to fly’. But, in 1895, eight years earlier, the Sanskrit scholar Shivkar Bapuji Talpade had designed a basic aircraft called Marutsakthi (meaning Power of Air) based on Vedic technology and had it take off unmanned before a large audience in the Chowpathy beach of Bombay. The importance of the Wright brothers lies in the fact, that it was a manned flight for a distance of 120 feet and Orville Wright became the first man to fly. But Talpade’s unmanned aircraft flew to a height of 1500 feet before crashing down and the historian Evan Koshtka, has described Talpade as the ‘first creator of an aircraft’.
As the world observes the one hundredth anniversary of the first manned flight, it is interesting to consider the saga of India’s 19th century first aircraft inventor for his design was entirely based on the rich treasury of India’s Vedas. Shivkar Bapuji Talpade was born in 1864 in the locality of Chirabazar at Dukkarwadi in Bombay.
He was a scholar of Sanskrit and from his young age was attracted by the Vaimanika Sastra (Aeronautical Science) expounded by the great Indian sage Maharishi Bhardwaja. One western scholar of Indology Stephen-Knapp has put in simple words or rather has tried to explain what Talpade did and succeeded!
According to Knapp, the Vaimanika Shastra describes in detail, the construction of what is called, the mercury vortex engine the forerunner of the ion engines being made today by NASA. Knapp adds that additional information on the mercury engines can be found in the ancient Vedic text called Samaranga Sutradhara. This text also devotes 230 verses, to the use of these machines in peace and war. The Indologist William Clarendon, who has written down a detailed description of the mercury vortex engine in his translation of Samaranga Sutradhara quotes thus ‘Inside the circular air frame, place the mercury-engine with its solar mercury boiler at the aircraft center. By means of the power latent in the heated mercury which sets the driving whirlwind in motion a man sitting inside may travel a great distance in a most marvellous manner. Four strong mercury containers must be built into the interior structure. When these have been heated by fire through solar or other sources the vimana (aircraft) develops thunder-power through the mercury.
NASA (National Aeronau-tical and Space Administra-tion) world’s richest/ most powerful scientific organisation is trying to create an ion engine that is a device that uses a stream of high velocity electrified particles instead of a blast of hot gases like in present day modern jet engines. Surprisingly according to the bi-monthly Ancient Skies published in USA, the aircraft engines being developed for future use by NASA by some strange coincidence also uses mercury bombardment units powered by Solar cells! Interestingly, the impulse is generated in seven stages. The mercury propellant is first vapourised fed into the thruster discharge chamber ionised converted into plasma by a combination with electrons broke down electrically and then accelerated through small openings in a screen to pass out of the engine at velocities between 1200 to 3000 kilometres per minute! But so far NASA has been able to produce an experimental basis only a one pound of thrust by its scientists a power derivation virtually useless. But 108 years ago Talpade was able to use his knowledge of Vaimanika Shastra to produce sufficient thrust to lift his aircraft 1500 feet into the air!
According to Indian scholar Acharya, ‘Vaimanika Shastra deals about aeronautics including the design of aircraft the way they can be used for transportation and other applications in detail. The knowledge of aeronautics is described in Sanskrit in 100 sections, eight chapters, 500 principles and 3000 slokas including 32 techniques to fly an aircraft. In fact, depending on the classifications of eras or Yugas in modern Kaliyuga aircraft used are called Krithakavimana flown by the power of engines by absorbing solar energies!’ It is feared that only portions of Bharadwaja’s masterpiece Vaimanika Shas-tra survive today.
The question that comes to one’s mind is, what happened to this wonderful encyclopaedia of aeronautical knowledge accumulated by the Indian savants of yore, and why was it not used? But in those days, such knowledge was the preserve of sages, who would not allow it to be misused, just like the knowledge of atomic bombs is being used by terrorists today!
According to scholar Ratnakar Mahajan who wrote a brochure on Talpade. ‘Being a Sanskrit scholar interested in aeronautics, Talpade studied and consulted a number of Vedic treatises like Brihad Vaimanika Shastra of Maharishi Bharadwaja Vimanachandrika of Acharya Narayan Muni Viman yantra of Maharish Shownik Yantra Kalp by Maharishi Garg Muni Viman Bindu of Acharya Vachaspati and Vimana Gyanarka Prakashika of Maharishi Dhundiraj’. This gave him confidence that he can build an aircraft with mercury engines. One essential factor in the creation of these Vedic aircraft was the timing of the Suns Rays or Solar energy (as being now utilised by NASA) when they were most effective to activate the mercury ions of the engine. Happily for Talpade Maharaja Sayaji Rao Gaekwad of Baroda a great supporter of the Sciences in India, was willing to help him and Talpade went ahead with his aircraft construction with mercury engines. One day in 1895 (unfortunately the actual date is not mentioned in the Kesari newspaper of Pune which covered the event) before an curious scholarly audience headed by the famous Indian judge/ nationalist/ Mahadeva Govin-da Ranade and H H Sayaji Rao Gaekwad Talpade had the good fortune to see his un manned aircraft named as ‘Marutsakthi’ take off, fly to a height of 1500 feet and then fall down to earth.
But this success of an Indian scientist was not liked by the Imperial rulers. Warned by the British Government the Maharaja of Baroda stopped helping Talpade. It is said that the remains of the Marutsakthi were sold to ‘foreign parties’ by the relatives of Talpade in order to salvage whatever they can out of their loans to him. Talpade’s wife died at this critical juncture and he was not in a mental frame to continue with his researches. But his efforts to make known the greatness of Vedic Shastras was recognised by Indian scholars, who gave him the title of Vidya Prakash Pra-deep.
Talpade passed away in 1916 un-honoured, in his own country.
As the world rightly honours the Wright Brothers for their achievements, we should think of Talpade, who utilised the ancient knowledge of Sanskrit texts, to fly an aircraft, eight years before his foreign counterparts.
