In particle physics, three out of the four known fundamental forces in the universe, namely electromagnetic, weak and strong interactions, are described by a theory known as the standard model (SM). One extension of this ...
Numbers like π, e and φ often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a ...
