Task: Text Categorization
Input (English): statement implies that for the liquid drop model, isotopes with unequal numbers of protons and neutrons will have a lower binding energy that decreases with the square of the number difference. This statement can be mathematically represented by determinants composed of spin orbitals, which change sign upon permutation of rows. Another consequence of it is the electron degeneracy pressure that supports the formation of white dwarfs, and it implies that electrons occupying the same orbital must have opposite spins. For 10 points, identify this statement which implies that no two fermions can possess the same quantum numbers, developed by an Austria physicist.
Output (English): Science
