Ol’ Gyroscopes

Gyroscope

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!

Precession

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

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

THE PORTALS OF HEAVEN
THE GOLDEN AND SILVER GATES
A Study of their Cosmic and Prophetic Significance
by Luis B. Vega, 2015

‘And to the Angel of the church in Philadelphia write: He who is Holy, who is True, who has the Key of David, who opens and no one will shut, and who shuts and no one opens, says this: ‘I know your deeds. Behold, I have put before you an Open Door [Gate] which no one can shut, because you have a little power, and have kept My word, and have not denied My name.’ – Revelation 3:7-8

The purpose of this study is to consider the concepts of the Golden and Silver Gates of the Cosmos. In light of the many assertions pertaining to the opening of ‘Gates’ or doors by CERN lately one has to appreciate the conceptualization of what the Golden Gate and Silver Gate alludes to. The Ancients knew that Gates or portals existed into other dimensions. One such knowledge is the concept of what the Golden Gate and Silver Gate are apparently in relation to the known Universe from Earth’s perspective. Continue reading

Dynamics of Protoplanetary Disks
By Philip J. Armitage, 2011

1. INTRODUCTION
Protoplanetary disks are the observational manifestation of the initial conditions for planet formation. They can be defined as rotationally supported structures of gas (invariably containing dust) that surround young, normally pre-main-sequence stars. Although most observed disks have inferred masses that are a small fraction of the stellar mass, no meaningful distinction can be drawn between physical processes in protoplanetary disks and those that occur in the earlier, protostellar phase, in which both star and disk are accreting rapidly. Similarly, a common set of processes operate, albeit to varying degrees, in disks around brown dwarfs, Classical T Tauri stars (low-mass pre-main-sequence stars that are actively accreting), and massive stars. A clear demarcation does separate protoplanetary disks from debris disks: dusty gas-poor structures around older stars whose properties reflect the collisional evolution of a population of small bodies (Wyatt, 2008).

Around low-mass stars, protoplanetary disks are persistent; the typical lifetime of ∼106 years (Haisch, Continue reading
