Therefore, the lunch remark of the day is: did you know that today is Wolfgang Pauli's birthday?
Wolfgang Pauli was born on April 25th, 1900 in Vienna. After receiving his early education in Vienna, he studied at the University of Munich under Arnold Sommerfeld. He obtained his doctor's degree in 1921 and spent a year at the University of Göttingen as assistant to Max Born and a further year with Niels Bohr at Copenhagen. (What I always liked most about quantum mechanics is that I know how to pronounce all the names of the people.)
Pauli is most famous for the exclusion principle which states that identical fermions (like electrons) can not occupy the same state. Thus, fermionic stuff can not clump together arbitrarily, and has an inherent stiffness. Among other things, the Pauli exclusion principle explains why electrons form nice shells around the atom core instead of all sitting in the lowest level, thus explaining the variety of chemical elements.
Wolfgang Pauli received the Nobel Price in 1945 "for the discovery of the Exclusion Principle, also called the Pauli Principle".
There are a lot of entertaining stories around Pauli, which is why he makes a good lunch topic. Among other things, he was known for spoiling experiments by simply being present in the room, an effect that was dubbed the 'Pauli-effect'. Allegedly, Otto Stern even banned Pauli from his laboratory to avoid the Pauli-effect, despite their friendship.
Wolfang Pauli was also known for ruthlessly criticising the work of his colleagues, from which the famous quotation stems
"This isn't right. This isn't even wrong."
("Das ist nicht nur nicht richtig, es ist nicht einmal falsch!")
Now let me publish this post... just in time for lunch. Have a toast to Pauli!
