Pseudoscalars, Polar Vectors, and Axial Vectors Source: Copilot exchange What is a pseudoscalar? A pseudoscalar is a quantity that behaves like an ordinary scalar under rotations, but changes sign under a parity transformation (mirror reflection or spatial inversion)....

Eight Nuclei in a Row The story of SS-7: how a formula written for the smallest atomic nuclei turned out, almost by accident, to predict the weights of nuclei a hundred times larger — and how the first thing that seemed wrong about the result, when it was finally...
