In Einstein's day, the strong and the weak forces had not yet been discovered, yet he found the potential existence of two other distinct forces, gravity and electromagnetism, far more alluring. This launched his 40-year voyage in search of the so-called "unified field theory" that he hoped would show that these two forces are really ...
One World or None established that throughout history, scientists from many nations have made great advances and discoveries and have shared that knowledge globally. The periodic table was developed by Russian chemist Dmitri Mendeleev, British scientist J. J. Thomson and his team discovered the principle of the electron, and German theorist Albert Einstein came up with the theory of relativity.

Einstein was so sure of a static universe that he developed the 'cosmological constant' and introduced 'anti-gravity' forces to allow a universe of infinite age to exist. Moreover, many astronomers also tried to avoid the implications of general relativity and stuck with their static universe, with one especially notable exception, the Russian ...
