At the heart of the understanding of nature is physics, or natural philosophy as it was known in Newton's time. As the Nineteenth Century drew to a close, it became clear that the world-view we inherited from Newton was not complete. Two great changes were on the horizon, in the form of relativity and quantum mechanics. Einstein had a hand in both, though his principal contribution was creation of the theory of relativity. On the other hand, calculus has withstood the test of time since Isaac Newton invented it to understand gravitation and the clockwork of our Universe. The mathematical tools Newton invented have served us for nearly 350 years. Learn about the ideas that have shaped our understanding of the Universe. Without them, we would know little of our origins or of our destiny.

Top Site The Albert Einstein Quiz I don't think it's easy to understand Einstein's work until you have had it explained by an ape. From: Steve Offner, essio@cavemen.net I wrote and submitted the following for the a limerick contest (Omni Magazine, 1979), however as far as I know it has never been published: A black hole - a tremendous creation Its physics defies imagination Time and space it can bend Wow! I can't comprehend The gravity of this situation What Is a Black Hole, Really? A black hole is a celestial object of such extremely intense gravity that it attracts everything near it and prevents everything, including light, from escaping. The term was first used in reference to a star in the last phases of gravitational collapse. Gravitational collapse begins when a star has depleted its steady sources of nuclear energy and can no longer produce the expansive force, a result of normal gas pressure, that supports the star against the compressive force of its own gravitation. In some cases, nothing remains to prevent the star from collapsing without limit to an indefinitely small size and infinitely large density, to create a black hole.

163. Gen. Relativity Cosmology An online notes from the University of British Columbia featuring simple explanations of cosmological phenomena. http://musr.physics.ubc.ca/~jess/p200/cosm/cosm.html

Next: Astronomy As Elementary Particle Physicists direct their attention ``down'' toward the indescribably tiny, so Cosmologists turn their gaze ``upward'' toward the unfathomably huge. Of course, these days both are increasingly likely to be incarnate in the same individual - I'll get to that later. As one who has never looked through a telescope larger than I could carry, I am certain to give short shrift to the magnificent observational science of astronomy , which provides cosmology (a theoretical discipline) with all its data. But a summary of the former without good colour plates of star fields and nebulae would be a terrible waste anyway, so I hope I have motivated the curious to go out and read a good Astronomy book on their own. Moreover, I am so ignorant of General Relativity and most of the fine points of Cosmology that I really have no business writing about either. Therefore I must content myself with a justification in terms of my ``unique point of view,'' whereby I excuse the following distortions. Astronomy Tricks of the Trade Parallax Spectroscopy ...

164. GrayAlbert A two part overview of the Shapiro radar bounce test of general relativity. (The two parts consist of a section for normal people, and one for nerds) http://world.std.com/~sweetser/PopScience/timeDelay/timeDelay.html

The time delay of radar reflections off of Mercury installation 1995 For Folks It takes a few minutes for light to get to Mercury from Earth, but it takes a little longer due to the Sun. Radar signals from the Haystack Observatory in Westford Massachusetts were sent out into space to bounce off Mercury. The time the radar signals spent flying between the two planets was carefully measured. As the radar's path in space moved closer to the Sun, a small time delay grew in the radar reflections which is given by equations in the big, black book (Gravitation, by Misner, Thorne and Wheeler). Written in chalk is the artist's method to calculate the time delay. The tools used come directly from quantum mechanics which is not supposed to be an aid for such a calculation. Yet the results are the same (equation 40.13). For Nerds Irwin I. Shapiro measured the time delay of radar reflections off Mercury caused by the gravitational field of the Sun. The logarithmic dependence on the impact parameter confirmed general relativity's prediction. The Lorentz group will be employed for a similar end. The gravitational fields for a bound test mass are characterized by a member of the Lorentz group in the following manner: take the Newtonian orbital velocity

He is perhaps the most well-known scientist of the 20th century. Einstein was born in Ulm on March 14, 1879, and spent his youth in Munich, where his family owned a small shop that manufactured electric machinery. He did not talk until the age of three, but even as a youth he showed a brilliant curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself Euclidean geometry.

Home About FAQ Lessons ... Reading Home Warp is a program used to illustrate the appearance of fast moving objects due to special relativity. Warp allows you to see what would happen to the appearance of objects as they reach extremely high speeds. We don't normally see these 'relativistic' effects because the speeds associated with every day life don't compare with the speed of light . To whet your appetite, here's what happens to Stonehenge at high speeds . . . Very strange! Anyway, if you want to learn more about special relativity then a good place to start is the about page. Once you've done that, try out the Warp special relativity simulator for yourself by downloading it! You'll now be wondering how to use Warp, so read the Lessons . If you still have questions, try the FAQ Finally, I've given you some links for those of you who want to learn more about Einstein's special relativity.

170. A Simple Model Of Waveform Particles. Theory Of Everything. Piers J Newberry. An outline of the theory of everything is here based on dense space which is readily derivable from relativity. http://website.lineone.net/~pierz/physics1.htm

HOME This article has been superceded go HERE for up date A Simple Model of Waveform Particles, Basis for a Theory of Everything Herein a simple model of wave form particle duality is presented. It has numerous ramifications for the formation of a unified theory. It is shown that the effective center of mass of particles moves with due to their spin causing them to adopt wave form characteristics. As this represents an explaination of one of the fundemental problems in physics the result produces many predictions for verification of the theory and some significant insights into sub atomic physics. NOTE REVIEWERS – This has been published in Physigma with the other paper. I am currently looking to get this published in a peer reviewed journal. However I have very little time and hope you will want to contribute to the paper to improve its quality. It is almost there. The first section is based on real observations, accepted physics and gives an important result it should without any doubt whatsoever be published. The sections under the title ‘Possible equivalence shown through electron diffraction’ are different in character. It is speculative and is present to give others a foundation for further investigation. Therefore you may wish to change or delete that section prior to submission for publication. Methods In fig 1 at the top of the sinusoidal cycle the particle has an anti-clockwise rotational movement. The bottom of the particle travels more quickly relative to the surrounding space than the top as its total velocity is the formed from the collusion of both vectors A and B. If the particle spins quickly the base of the particle gets heavier according to E = mc

General Relativity General Physics FAQs Can Theoretical Physics explain paranormal phenomena? Answer courtesy: Nobel Laureate Gerald t'Hooft What if all things can't be explained using physics? This is certainly a possibility, however, if physics and mathematics is inadequate to describe reality, that only leaves a realm that would be useless for us to know anyway. Besides "to know" means to apply a logical system to describe something, if mathematics (logic) is not applicable what else would one use? Faith is not an alternative to logic, for it is based on logic. One could define faith as the group of prejudices established by one to avoid reason. What is theoretical physics?

172. A Unified Theory That Generates Relativity And Quantum Mechanics. Geometric Gene GSN is a conceptual theory, which generates relativity and Quantum Mechanics. GSN identifies the basic principles of nature. http://www.morfarch.com/gsn.html

Geometric Generalization of the Structure of Nature M. Erk Durgun erkdurgun@yahoo.com erkdurgun@morfarch.com http://www.geocities.com/erkdurgun/gsn.html http://www.morfarch.com/gsn.html For your comments: http://groups.yahoo.com/group/GeometricStructureofNature/ Attention Please This web page is not intended to present educational information on conventional modern physics. Abstract Geometric Generalization is a conceptual theory, which generates Relativity and Quantum Mechanics. Geometric Generalization is based on a radical hypothesis on fundamental particles. Correlations of this hypothesis identify and formulate the basic principles of nature. A concrete re-definition and formulation of mass and time, mechanism of gravity at particle scale and formation principles of fundamental particles will be presented according to these basic principles. Geometric Generalization reduces nature to continuous extension of strings by the Universal expansion. Derivation of Lorentz Transformation Equations from Geometric Generalization, a few verifiable predictions are also included. Table of Contents 1. Introduction
