Today we introduce you about an Austrian man who was a true genius, comparable only to . In 's words, "As a scientist he was, perhaps, even greater than Einstein. But he was a completely different type of man, who, in my eyes, did not attain Einstein’s greatness.” That Austrian genius is our "scientist of the day" today.

It's death anniversary of , one of the most physicists of the twentieth century --

(Scientist of the Day - 15 December)

His most famous work, the principle was formulated in 1925 for electrons, and later extended to all with his theorem of 1940. For this exclusion principle, he received the 1945 Nobel Prize in Physics after having been nominated by Albert Einstein.

In 1930, Pauli considered the problem of decay. In a letter of 4 December to et al., beginning, "Dear radioactive ladies and gentlemen", he proposed the existence of ....
