It always baffles me to think how much abstractions that Einstein's mind could contain. His philosophical, political, and scientific views reflect his sheer ability to make abstractions from first principles. Also, what is more baffling is his sheer ability to sustain those thoughts in his minds for years. The whole progression of thoughts regarding special relativity/general relativity went on for more than a decade with few years of intense work in-between. Einstein exemplified the power of devising thought experiments in mind and then substantiating those thought experiments with reasoning, observation and math for years to come. Interestingly, he failed to persuade the world leaders to destroy nuclear weapons that were threat to human kind and were not that useful in the actual war events.Say something about our greatest mind finds hard to do. Btw, I love his humor.
