Pauli Exclusion Principle

In the three-dimensional space in which we live, elementary particles are designated as fermions and bosons, depending on their spin. We associate with each variety of elementary particle a quantum number, which gives the value of its spin. This number can be an integer (0,1, 2,... ) or a half integer (1/2, 3/2, 5/2,...). Particles with integer spin are called bosons, and particles with half integer spin are called fermions. The quantum mechanical behavior of fermions and bosons is different:...

 Adam and Eve are a Religious Variable

“But…” Lyra struggled to find the words she wanted: “but it en’t true, is it? Not true like chemistry or engineering, not that kind of true? There wasn’t really an Adam and Eve? The Cassington Scholar told me it was just a kind of fairy tale.” “The Cassington Scholarship is traditionally given to a freethinker; it’s his function to challenge the faith of the Scholars. Naturally he’d say that. But think of Adam and Eve like an imaginary number, like the square root of minu...
