Today we celebrate the birthday of Albert Einstein -- the first person to suggest that space can be curved. More -- after this. March 14 A Toast to Einstein We celebrate a great anniversary today -- the anniversary of the birth of Albert Einstein. More than any other scientist, Einstein changed our modern picture of the universe. Before him, it was thought that outer space -- existed independently of the material universe. It was thought that space had always been there, even before the birth of stars and galaxies. Einstein's theory of relativity changed this view. Relativity theory describes the universe of space and matter as a whole -- an interlocking unit. In our understanding of the universe, space did not exist before the Big Bang in which the universe is thought to have been born. The structure of space can change, said Einstein. It can expand, as the universe expands. Or it can curve in bizarre and incredible ways, as in the area around a black hole. Einstein was born on March 14, 1879. He was educated first in Germany, then in Switzerland. In 1902, he found work in a mid-level Swiss government job -- a patent office. The job gave him money to live on -- and free time to work in physics. He published his special theory of relativity in 1905. That's the one that deals with the interconnectedness of space and time. In 1915, he published the general theory of relativity, which describes the nature of space itself. Before his death in 1955, Einstein had become famous as one of the world's great scientists, whose originality changed the way we perceive the universe. Script by Deborah Byrd.

> Am I the only one who finds the tripe > emanating from "StarDate" to be often annoying? Perhaps the author of this flame should read net.astro.expert instead of net.astro. I, for one, very much appreciate the efforts of Debbie and the others at utastro. I suspect that those of us who are *not* experts in astronomy considerably outnumber those who are. Keep up the good work, Debbie. -- The opinions expressed are not necessarily those of my employer, the government or your favorite deity. Charlie Sorsby ...!{cmcl2,ihnp4,...}!lanl!crs crs@lanl.arpa

In particular, the distinction between curved space and curved space-time is important, but usually ignored in popular accounts. Gauss measured the angles of a large triangle in Germany to see whether or not the three angles added up to 180 degrees experimentally. He concluded that one could not yet tell. Einstein was the first to *successfully* use non-Euclidean geometry in describing the mathematics of space-time. On the way to his general theory of relativity, he had tried a theory which just involved the curvature of space, still treating time as something separate. This theory gave the correct prediction for the precession of Mercury's orbit, but gave a value for the deflection of light by the sun one-half of the correct value. Riemann in the mid 19th century had tried using his geometry to base a theory of gravitation on. He missed the importance of space-time as opposed to just space. My memory is fuzzy on failed theories of gravitation, but I seem to recall Ni in 1913 proposed a theory of relativity involving curved space-time. He had the right idea but the wrong field equations. We all hear about the success stories in the history of science, but there are a lot of fascinating close misses. ucbvax!brahms!weemba Matthew P Wiener/UCB Math Dept/Berkeley CA 94720

[] My feelings exactly! There are those of us who enjoy reading the StarDate articles...without them I would have missed several events that I enjoyed a great deal. Mr. Gene Ward Smith, there are those of us out here in netland who have the ability to read what is on the screen and get information out of it, rather than nit-picking the "tone" in which the information is displayed. If you find it so annoying, why not just skip the article? I find it rather pleasant to read StarDate and I enjoy the tone of it also since I am not an expert in astronomy and have been rather annoyed at the tone of other articles, those from the experts who assume that everyone else is as learned as they are. And by the way, being of Italian descent, tripe is one of my favorite dishes... -- Adrian Zannin SUNY at Buffalo Computer Science ..{bbncca,decvax,dual,rocksvax,watmath,sbcs}!sunybcs!ugzannin CSNET: ugzannin@Buffalo.CSNET ARPANET: ugzannin%Buffalo@csnet-relay.ARPA BITNET: ugzannin@sunybcs.BITNET

Not *everyone* in net.astro is an expert, that's why net.astro.expert exists, I imagine. StarDate in *that* group would be an- noying to some people I sure, since it would be couched in ordinary speech instead of undecypherable mega-talk. I vote to keep StarDate: any information you didn't know before is valuable. mega-talk. -- The Phoenix (Neither Bright, Dark, nor Young) ---"A man should live forever...or die trying." ---"There is no substitute for good manners...except fast reflexes." ---"Never appeal to a man's "better nature".
