Task: Text Categorization
Input (English): As the weak charge is not invariant under a reflection unless particles are replaced by their antiparticles as well, the fundamental laws of physics may well have this property. It can arise in spiranes and allenes due to their cumulated bonds and restricted rotation. Many familiar objects, such as the S and Z tetronimoes in Tetris, possess this property, with a pair being enantiomorphic. FTP, name this property that states that a molecule is not superimposible over its mirror image.
Output (English): Science
