James Clerk Maxwell
Newton unified physics and astronomy: this was the first great unification in physics. Maxwell unified electricity and magnetism – the second great unification. James Clerk Maxwell should be as well known as Newton. Newton has his three laws. Maxwell has four equations. We can understand Newton’s laws at high school, but we have to wait until we have studied enough mathematics to understand Maxwell’s equations. That’s why he is not well known – it looks like code.
But even without the maths, we can understand what the equations mean.
