John Stewart Bell----He's the physicist that i respect and admire most now. Born in Ireland,1928, John Bell grew in a non well-off family. (his father was a blacksmith).......but he nvr gave up to further his study........he was a lab assistant in his university before he was a student there due to the financial limit of his family.......Bell is one of the most important Quantum physicist in his age.........his most important discovery in physics--Bell's Theorem or Bell's Inequality had been known as the fundamental idea to Quantum Information Technology and Quantum Crytography.......... below is wat I quote from the American magazine--PhysicsWorld:Quantum theory is the most successful scientific theory of all time. Many of the great names of physics are associated with quantum theory. Heisenberg and Schrödinger established the mathematical form of the theory, while Einstein and Bohr analysed many of its important features. However, it was John Bell who investigated quantum theory in the greatest depth and established what the theory can tell us about the fundamental nature of the physical world.
Moreover, by stimulating experimental tests of the deepest and most profound aspects of quantum theory, Bell's work led to the possibility of exploring seemingly philosophical questions, such as the nature of reality, directly through experiments.
And this was just Bell's "hobby".
