Einstein: Papers
built 643 days ago
To be honest... for a high-end theoretical physicist, Einstein's math was subpar. His earlier papers -- while elegant, brief, and brilliant -- often contain simple errors. However, it must be remembered the Einstein was not balancing a checkbook, he was balancing the forces of gravity and the speed of light. The level of mathematics he was doing is far beyond two-plus-two. And so it's more correct to say that Einstein wasn't a mathematician -- and that he needed their help quite often to make sure his theories did pan out in the end.

Einstein wrote three fundamental papers, all in a few months. The first paper claimed that light must sometimes behave like a stream of particles with discrete energies, "quanta." The second paper offered an experimental test for the theory of heat. The third paper addressed a central puzzle for physicists of the day – the connection between electromagnetic theory and ordinary motion – and solved it using the "principle of relativity."

In his early days in Berlin, Einstein postulated that they correct interpretation of the special theory of relativity must ... furnish a theory of gravitation, and in 1916 he published his paper on the general theory of relativity. During this time, he also contributed to the problems of the theory of radiation and statistical mechanics. In the 1920s, he embarked on the construction of unified field theories, continuing to work on the probabilistic interpretation of quantum theory, and he persevered with this work in America. He won a Nobel Prize for Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." He contributed to statistical mechanics by his development of the quantum theory of a monatomic gas, and he has also accomplished valuable work in connection with atomic transition probabilities and relativistic cosmology.

A second paper (Neuroscience Letters, 1996) describing Einstein's brain was published in 1996. Einstein's brain weighed only 1,230 grams, which is less than the average adult male brain (about 1,400 grams). The authors ... reported that the thickness of Einstein's cerebral cortex (area 9) was thinner than that of five control brains. However, the DENSITY of neurons in Einstein's brain was greater. In other words, Einstein was able to pack more neurons in a given area of cortex.

In 1940 Einstein became a citizen of the United States, but chose to retain his Swiss citizenship. He made many contributions to peace during his life. In 1944 he made a contribution to the war effort by hand writing his 1905 paper on special relativity and putting it up for auction. It raised six million dollars, the manuscript today being in the Library of Congress.

Einstein reads of Wilhelm Wien̢۪s paper surveying the current state of Ether Physics, presented to an international conference in September 1898. Wien̢۪s first sentence highlights the confusion in physics at the end of the 19th century.
