GCLC is a mathematical software tool for producing high-quality mathematical illustrations, for teaching mathematics, and for automated proving of geometry theorems.

Perturbation theory works well in EM because successive powers of the EM coupling constant, alpha ~ 1/137, get smaller fast. But that does not happen for the entire energy spectrum of QCD.

Chemistry, mathematics and physics are central to our understanding of nature. Physics explores the fundamental laws of mechanics, electromagnetism, quantum mechanics and relativity. Chemistry studies ...
