This most attractive example is in the apparatus collection at Bowdoin College. It has no maker’s name and is about 40 cm high.
The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth. The better-known demonstration of the Foucault pendulum showed that the plane of rotation of a freely-swinging pendulum rotated with a period that depends on the latitude of its location.
His gyroscope was a rapidly rotating disk with a heavy rim, mounted in low-friction gimbals. As the earth rotated beneath the gyroscope, it would maintain its orientation in space. This proved to be hard to do in practice because the frictional forces bring the spinning system to rest before the effect could be observed. The gimbal bearings also introduce unwanted torque. But, the principle is well-known to all children who move their toy gyroscopes about and observe that the spinning disk stays in the same orientation. Continue reading
How Gyroscopes Work
by M. Brain
Gyroscopes can be very perplexing objects because they move in peculiar ways and even seem to defy gravity. These special properties make gyroscopes extremely important in everything from your bicycle to the advanced navigation system on the space shuttle. A typical airplane uses about a dozen gyroscopes in everything from its compass to its autopilot. The Russian Mir space station used 11 gyroscopes to keep its orientation to the sun, and the Hubble Space Telescope has a batch of navigational gyros as well. Gyroscopic effects are also central to things like yo-yos and Frisbees!
If you have ever played with toy gyroscopes, you know that they can perform all sorts of interesting tricks. They can balance on string or a finger; they can resist motion about the spin axis in very odd ways; but the most interesting effect is called precession. This is the gravity-defying part of a gyroscope. Continue reading

Buried for most of its life in the desert sand, an air of mystery has always surrounded the Great Sphinx, causing speculation about its age and purpose, method of construction, concealed chambers, role in prophecy, and relationship to the equally mysterious pyramids. Much of this theorizing is to the despair of Egyptologists and archaeologists.
The Mystery of the Great Sphinx
Facing the rising sun, the Great Sphinx is located on the Giza plateau, about 10 km west of Cairo, on the west bank of the Nile River. Later Egyptian rulers worshipped it as an aspect of the sun god, calling it Her-Em-Akhet (“Horus of the Horizon”). The Sphinx sits in part of the necropolis of ancient Memphis, the seat of power for the pharaohs, a short distance from three large pyramids – the Great Pyramid of Khufu (Cheops), Khafre (Chephren) and Menkaura (Mycerinus).

Star of David – THE Cosmic countdown
Alignments, Symmetry & Patterns from 1990-2013
By Luis B. Vega, 2013 [Excerpted]
The purpose of this study, with chart for illustration (see link above) is to highlight a key celestial occurrence in the Heavens called the Star of David planetary alignment. The focus of the timeline presented will be from the most recent occurrences in our modern time. Starting from 1990 to 2013, these peculiar planetary alignments seem to be clustered. In particular, since 1990, there are 13 Star of David configurations that occur. The 13th occurrence is the ‘last one’ leading up to the Tetrad of 2014-2015. (See Dissection of a Tetrad chart) After 2013, there will not be another such configuration of either a Tetrad or Star of David alignment for another 100 years or so.
The Star of David alignments appears to follow a ‘countdown’ sequence or frequency of sorts. It very much appears to be like the Total Solar Eclipses that occurred consecutively on the 1st of Av in 2008, 2009 & 2010. Those 3 consecutive Eclipses appeared to signal the ‘countdown’ to the start of the 7-Year Solar-Lunar pattern. (See Solar Eclipse pattern chart) It appears that this same principle or ‘astronomical law’ is at work here with the Star of David alignment pattern & symmetry. The pattern Continue reading
Heh and Hauhet, Deities of Infinity and Eternity
By Caroline Seawright
The ancient Egyptians [KMT] believed that before the world was formed, there was a watery mass of dark, directionless chaos. In this chaos lived the Ogdoad of Khmunu (Hermopolis), four frog gods and four snake goddesses of chaos. These deities were Nun and Naunet (water), Amun and Amaunet (invisibility), Heh and Hauhet (infinity) and Kek and Kauket (darkness).
The water stretched infinitely off in all directions, as ever lasting as time itself. Heh and Hauhet came to symbolise infinity. After time began, Heh and Hauhet came to symbolise limitless time, and long life.
The frog or human headed god Heh (Huh) was one of the original eight gods of the Ogdoad of Khmunu Continue reading
