The Brain of Einstein, a Question I have a foggy understand of Special Relativity, and understand that it was understood previously without a real theory by Lorenz, but the General Theory was such a shot coming out of nowhere, without physical validation, that is impossible to understand the mathematical capability, imagination, intuition and the certainty with which Einstein presented it. In Math I have heard the question, "How do you know you are right?" Well, a problem can be approached by many avenues, so there are many checks on the work. In Physics I assume the checks largely come from experimental verification, you try this experiment and then you modify your hypothesis. This work of Einstein has no parallel, is it the greatest achievement of the human intellect in History? Was his brain no different than that of others? Was it merely a lucky guess, or did his intuition have some special ability, or was it--at least to him--just a question of following the most logical course? Newton, after all, had many reasons to know he was right, and the work was scarcely criticized, yet with Einstein, there was much to verify even after his death, even today, such as in 1971 sending up planes with atomic clocks to discover a time dilation on the order of one ten millionth of a second. And remember we have a problem with the rotation of the earth, and with the time dilation caused by gravity. How could he have thought of this? How could this be?
