If Albert Einstein lived today, what would he do for Science?

He didn't invent a branch of science when he was alive, and there's no reason to think he would invent one if he were alive now. He extended the science of physics.

there is only 3 branches in science, physics, biology and chemistry, and they all really boil down to physics and evolution. so really, there could be no other branches, because that would fall under philosophy.. so really, its bio and physics, thats it.

I suggest u do some creative work and get fulfilled ...Like him rather discussing :) Or assist someone http://www.mylot.com/w/discussions/1107440.aspx

What are doing today ? seeking the past which can't be true?????

I don't think we can speculate on what he could do today. Some people even say that he was not that smart. But who knows what could happen. We could ask if Adolf Hitler win the war, how the world would be today... This are things we will never know, and the best thing is to think in the future not in the past.
