#33 Dirac Mood

Paul Dirac had a very quiet and taciturn nature. His colleages in Cambridge even defined an unit, the "dirac", which represents the minimun amount of words that can be spoken on a conversation. Thoroughly, a word per hour. If you want to know more about Dirac, hey, you just have to search for him in Wikipedia.

This joke came to me after a conversation with my dear friend Paloma (a.k.a Palomeision) in which we both were particularly... monosyllabic. Then, after a long silence, she said to me 'feeling Dirac today?'. I laughed a lot.

#32 Pauli's

This one is for my classmate Jorge, who had the idea.

Pauli's exclusion principle establishes that two identical fermions can't be found in the same quantum state at the same time.

#30 Chandrasekhar Limit

Chandrasekhar limit is the maximum mass of a stable white dwarf star. If the white dwarf core reaches a mass above that limit, which is about 1,44 times  the solar mass, the electron degeneracy pressure is insuffcient to balance the gravitational self-attraction of the collapsing dead star and it can end up as a neutron star or even into a black hole if the mass is high enough.
