. >> and his paper on relativity blew isaac newton out of the water in isaac newton's, what, 200 yeareptance of his formula with regardto weight and space and light, gravi$y? >> that really applies more to general relativity, so i mean blowing newton out of the water as the "new york times" said heaven's all askew. einstein surpasses newton. that really is for the general relativitywhich is papers that he did at the end of 1915, 1916. moving bodies, his specl theory of relativity establishes the equivalence of mass and energy. this is the famous e equals mc squared equati that later is falsely claimed to make him the father of the atomic bomb. >> e stands for energy,@m stands for mass. the small c a. >> speed of light. >> a term of science. the c itself is the speed of light and you square the speed of light and then matter and matter becomes interchangeable with -- >> eney. >> with energy. >> yes. >> and this of course is at a very sic level the sec"et to the atomic bomb. , of course, rejected with i@ think complely correctly rejected the idea that he had pa trntty of the atomic bomb

benjamin franklin is said to be the isaac newton of electricity, an enormously prominent scientist in his day before the 13 colony-type thing and before signing the declaration of independence. ben franklin, he did a lot in electrostatics. so this then is negatively charged and the cat's fur then would be? positive. positive. which, by the way, underlies a very important principle called the conservation of charge. and the conservation of charge simply says that, "hey, gang, whatever charge you got, "it's what you got. "you don't make any more, you don't make any less. all you do is transfer it from one place to another." it's like maybe a brick road. there's so many bricks in the road. now, you take some of the bricks off the road and put them on the sidewalk. what's the total number of bricks i have before and after? same. the same. i've just put them from one place to another. and every brick in the sidewalk is matched by a hole in the road. do you see that? so we just take it from place and put another. so if i put a certain charge on here-- let's say a millionth of a coulomb-- co
