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 – ...

Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More ...

I have pursued an approach through classical electromagnetism to derive the expression of energy ejw, which is equal to Einstein's concept of light quanta or photons. I have further argued that the ...

Global conflicts are making renewable energy more attractive, but an all-renewable grid will require solving physics problems ...
