A set of mathematical methods for obtaining approximate solutions to complex equations for which no exact solution is possible or known, generally involving an iterative algorithm in which each new term contributing to the solution has less significance than the last. In quantum physics, Feynman diagrams are used to calculate the terms for the perturbation theory solution of interactions between particles.
TV Shows And Songs That Improved Our VocabularyWhile some TV shows might not make us smarter (that's right reality TV, we're talking to you), there are others (and popular songs, too) that help enhance our language skills. We take a look at ten songs and shows that help improve our vocabulary.
