General relativity: a very weird world This is the English translation of a webpage originally written in French , by Nymbus , who also provided the translation. I've agreed to post it here at my own website, and have cleaned up the translation a bit, editing for grammar, and so on, but leaving the content untouched, I think. So any comments or questions should be addressed to nymbus@wanadoo.fr . It's his project. (Although, if there's a problem with the page such as the images not showing up or special characters not appearing, send word to me .) Dave This page has also been translated into Spanish At times, this page alludes to concepts from the special theory of relativity, which are explored here General relativity: a brief explanation of the fundamentals ideas Before beginning this brief article, dealing with the essential features of general relativity, we have to postulate one thing: special relativity is supposed to be true. Hence, general relativity lies on special relativity. If the latter were proved to be false, the whole edifice would collapse. In order to understand general relativity, we have to define how mass is defined in classical mechanics.

Clinton is not an adulterer by Larry Judkins Religion Page Editor Sacramento Valley Mirror Index: Atheism and Awareness (Editorials) Home to Positive Atheism I know, I know! After reading that headline, you think I'm a rabid Democrat who's in denial about President Clinton's extramarital affairs. Actually, long before Mr. Clinton's own admissions, I accepted as true the allegations of both Monica Lewinsky and Gennifer Flowers. I have also never doubted Paula Jones or Kathleen Willey. So how, then, can I maintain that President Clinton is not an adulterer? Simple. From a biblical perspective or at least an Old Testament perspective he has not committed adultery. Remember that in Old Testament times, polygamy and concubinage were perfectly acceptable institutions, and no "sin" or immorality was associated with them. Generally speaking, men could have as many women as they could acquire. A man was considered an adulterer only if he had sexual relations with another man's wife. If a married man had sex with an unmarried woman, he was not guilty of adultery. Thus, King David was an adulterer only because of his relationship with Bathsheba, the wife of Uriah the Hittite. His many other legally acquired wives and concubines did not make him guilty of adultery.

Dave's Relativity Page or "Time Flies When You're Going Nowhere" Think Einstein's Theory of Relativity is only for rocket scientists? Well, I've got news for you. I don't think even rocket scientists need to know relativity most of the time! (At least not rocket scientists for the next century or two.) But that doesn't mean you can't learn about it right now. This page and the others linked to it are an introduction to relativity with (almost) no math at all. It's not meant to be complete by any means, but its purpose is to help you understand the principles on which the Special Theory of Relativity is based, and know a few of its more famous implications. First of all, a few words about the scope of this project. The theory of relativity is actually a two-fold work. First, there's the Special Theory of Relativity, published in 1905. This was basically Einstein's resolution of some paradoxes involving the speed of light, and it describes the behavior of objects at very high speeds. About ten years later, Einstein published the General Theory of Relativity, an altogether more mind-blowing theory which provides a more precise description of gravity than Isaac Newton did. Here you will read only about Special Relativity, since I don't know enough about General Relativity to explain it to anyone. But hopefully what's here will be enough for you to enjoy and learn from.

53. NOVA Online/Einstein Revealed/Relativity (Lightman Essay) The author describes relativity. http://www.pbs.org/wgbh/nova/einstein/relativity/relativity2.html

The possibility that stars could collapse to form black holes was first theoretically "discovered" in l939 by J. Robert Oppenheimer and H. Snyder, who were manipulating the equations of Einstein's General Relativity. The first black hole believed to be discovered in the physical world, as opposed to the mathematical world of pencil and paper, was Cygnus X-1, about 7000 light years from earth. (A light year, the distance light travels in a year, is about six trillion miles.) Cygnus X-1 was found in 1970. Since then, a dozen excellent black hole candidates have been identified. Many astronomers and astrophysicists believe that massive black holes, with sizes up to ten million times that of our sun, inhabit the centers of energetic galaxies and quasars and are responsible for their enormous energy release. Ironically, Einstein himself did not believe in the existence of black holes, even though they were predicted by his theory. Beginning in 1917, Einstein and others applied General Relativity to the structure and evolution of the universe as a whole. The leading cosmological theory, called the Big Bang theory, was formulated in 1922 by the Russian mathematician and meteorologist Alexander Friedmann. Friedmann began with Einstein's equations of General Relativity and found a solution to those equations in which the universe began in a state of extremely high density and temperature (the so- called Big Bang) and then expanded in time, thinning out and cooling as it did so. One of the most stunning successes of the Big Bang theory is the prediction that the universe is approximately ten billion years old, a result obtained from the rate at which distant galaxies are flying away from each other. This prediction accords with the age of the universe as obtained from very local methods, such as the dating of radioactive rocks on the earth.

So if you feel like I'm off to the side of the tale half the time, well, this is why. Just bear with me, and we'll get to the end in good time. Okay? Okay. Let's see.... [ I ] Say you woke up one day and your bed was gone. Your room, too. Gone. It's all gone. You wake up in an inky void. Not even a star. Okay, yes, it's a dumb idea, but just go with it. Now say you want to know if you move or not. Are you held fast in one spot? Or do you, say, list off to the left some? What I want to ask you is: Can you find out? Hell no. You can see that, sure. You don't need me to tell you. To move, you have to move to or away from ... well, from what? You'd have to say that you don't even get to use a word like "move" when you are the only body in that void. Sure. Okay.

56. NOVA Online/Einstein Revealed/Relativity (Lightman Essay) relativity and the Cosmos. General relativity was the first major new theory ofgravity since Isaac Newton's, more than two hundred and fifty years earlier. http://www.pbs.org/wgbh/nova/einstein/relativity/

Relativity and the Cosmos by Alan Lightman In November of 1919, at the age of 40, Albert Einstein became an overnight celebrity, thanks to a solar eclipse. An experiment had confirmed that light rays from distant stars were deflected by the gravity of the sun in just the amount he had predicted in his theory of gravity, General Relativity. General Relativity was the first major new theory of gravity since Isaac Newton's, more than two hundred and fifty years earlier. Einstein became a hero, and the myth building began. Headlines appeared in newspapers all over the world. On November 8, 1919, for example, the London Times had an article headlined: "The Revolution In Science/Einstein Versus Newton." Two days later, The New York Times' headlines read: "Lights All Askew In The Heavens/Men Of Science More Or Less Agog Over Results Of Eclipse Observations/Einstein Theory Triumphs." The planet was exhausted with World War I, eager for some sign of humankind's nobility, and suddenly here was a modest scientific genius, seemingly interested only in pure intellectual pursuits. What was General Relativity? Einstein's earlier theory of time and space, Special Relativity, proposed that distance and time are not absolute. The ticking rate of a clock depends on the motion of the observer of that clock; likewise for the length of a "yard stick." Published in 1915, General Relativity proposed that gravity, as well as motion, can affect the intervals of time and of space.

59. Theory: Special Relativity A brief overview of the theory of special relativity, and how it pertains to particles at SLAC (Stanford Category Science Physics relativity Special relativity......Theory Special relativity. Newton's laws of motion give Theoretical Basisfor Special relativity. Einstein's theory of special relativity http://www2.slac.stanford.edu/vvc/theory/relativity.html

Special Relativity Newton's laws of motion give us a complete description of the behavior moving objects at low speeds. The laws are different at speeds reached by the particles at SLAC. Einstein's Special Theory of Relativity describes the motion of particles moving at close to the speed of light. In fact, it gives the correct laws of motion for any particle. This doesn't mean Newton was wrong, his equations are contained within the relativistic equations. Newton's "laws" provide a very good approximate form, valid when v is much less than c . For particles moving at slow speeds (very much less than the speed of light), the differences between Einstein's laws of motion and those derived by Newton are tiny. That's why relativity doesn't play a large role in everyday life. Einstein's theory supercedes Newton's, but Newton's theory provides a very good approximation for objects moving at everyday speeds. Einstein's theory is now very well established as the correct description of motion of relativistic objects, that is those traveling at a significant fraction of the speed of light. Because most of us have little experience with objects moving at speeds near the speed of light, Einstein's predictions may seem strange. However, many years of high energy physics experiments have thoroughly tested Einstein's theory and shown that it fits all results to date.
