The life of Albert Einstein - part 5

Video Title :	The life of Albert Einstein - part 5
Description :	He is best known for his theory of relativity and specifically mass-energy equivalence, E = mc2. Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."[1] Einstein's many contributions to physics include his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity, which extended the principle of relativity to non-uniform motion, creating a new theory of gravitation. His other contributions include relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian movement of molecules, atomic transition probabilities, the quantum theory of a monatomic gas, thermal properties of light with low radiation density (which laid the foundation for the photon theory), a theory of radiation including stimulated emission, the conception of a unified field theory, and the geometrization of physics. http://www.bbc.co.uk/sn/tvradio/programmes/horizon/einstein_symphony_prog_summary.shtml Another BBC doc on subject - Einstein's Unfinished Symphony http://www.youtube.com/watch?v=2GnZ1n7no3M&feature=related

Actually imermetaj, if you could travel around the earth at close to the speed of light, and you looked at your watch, it would still appear to be ticking at its normal rate. Special relativity says that a stationary observer would notice that your watch isnt ticking at all. a moving watch and a stationary watch both tick at different rates relative to the moving observer.

That wasn't a good example hellgas0 gave you. What elgas0 said is true but does not answer your particular question. good example=if you could travel the speed of light, time would equal zero therefore you would be stuck at one time. amozoness1 would be living with the normal time and amozoness2 would be stuck which means slow down in life lol. amozoness1 could leave amozoness2 clues about the future (present normal life) for amozoness2 to see. This is theory though, in reality its imposible.

You didn't answer my question. He and/or she did.

Actually, he/she/it didn't do a very good job either. Reread my question and try again.

No offence but i don't think you actualy know what your own question is lol. Simpmle. If you could orbit Earth at the speed of light (wich is imposible in reality) you could be stuck in year 2008 wile the rest of us keep going in time. your "watch" would not be moving wile mine will. Make sense?

I'm not talking specifically about at the speed of light so get off of that. I'm talking about IN GENERAL, what does it mean for "time" to slow down or speed up? You still don't understand my question. HOW IS A CHANGE IN TIME CALCULATED? WHAT DOES A CHANGE IN TIME ACTUALLY MEAN?

omg lol thats what the theory of relativity is man. TIME IS RELATIVE. time varies on ones motion. if one speeds up that means time slows down thats what Einsteins formula says and his theory.

YOU AREN'T LISTENING.WHAT DOES A CHANGE IN TIME MEAN? I don't understand what a change in time means. Time is just a measure of a clock's hand movement, so what is time slowing down/speeding up?

It says you can see the concluding part... is there more to this documentary?? Either way, thank you so much for uploading it!

So far I have not found a concluding part to this documentary, however I put a link in the side bar to another BBC doc entitled Einstein's Unfinished Symphony, its worth watching. And you're welcome for the upload.
