Further to the article posted by Randy (submitted by Ewan Hill) I came across this article, “You Decide: What is the Most Beautiful Equation?” from the BBC Earth website. I was researching the Dirac equation, one of the numerous equations illustrating the January 20 Science Seminar presentations.
BBC Earth asked mathematicians and physicists to tell us which equations they think are the most beautiful. Their choices range from explanations of antimatter to predicting how sub-atomic particles behave.
