Maxwell’s equations of electromagnetism and the Euler equation top a poll to find the greatest equations of all time. Robert P Crease discusses the results of his reader survey First among equals – ...

Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Physicists’ main goal is to be able to predict what will happen in the future based on patterns they’ve already observed, whether in massive systems of stars or tiny groups of atoms. Predicting ...
