There is no record of Einstein's blood type, but there is speculation among the public that Einstein's blood type is AB, because type AB has always been called the blood type of genius, and the phrase "genius combined with diligence" comes from love. Einstein's famous saying can perfectly explain this man's blood type.

Einstein is one of the most creative and intelligent figures in human history and one of the main creators of quantum theory. He created four fields of physics in his life: special relativity, general relativity, cosmology and unified field theory.

Einstein's academic career

In 1908, he was recognized as an outstanding scientist and was appointed lecturer at the University of Bern. The following year, after giving a lecture on the principles of electrodynamics and relativity at the University of Zurich, Alfred Kleiner recommended him to become a teacher in the newly established Department of Theoretical Physics. Einstein was appointed associate professor in 1909.

Einstein became a full professor at the German Charles Ferdinand University in Prague in April 1911, and thus obtained Austrian citizenship in the Austro-Hungarian Empire. During his stay in Prague, he wrote 11 scientific works, 5 of which were on the mathematics of radiation and quantum theory of solids. In July 1912, he returned to his alma mater in Zurich.

From 1912 to 1914 he was professor of theoretical physics at the ETH Zurich, where he taught analytical mechanics and thermodynamics. He also studied continuum mechanics, molecular thermal theory, and problems of gravity, working with mathematician and friend Marcel Grossmann.
