In the following paragraph, what does "grand unification of physics" refer to please? The question may seem a bit technical, but I thought someone could clarify the meaning. Thanks in advance!
"These waves were the real proof that Maxwell was correct in his predictions and that by only using mathematical tools, he had succeeded in unifying electricity, magnetism and optics, a feat that inspired the great physicists of the twentieth century. Following the example of Maxwell, Albert Einstein tried in vain to incorporate the force of gravity into the grand unification of physics, a challenge that is still pending."
Einstein spent his later years working on a unified field theory. Here are a couple of links. There is lots more info online.
