Since the mathematicians have invaded the theory of relativity I do not understand it myself any more.

— Albert Einstein

“Accelerating to speeds faster than light was, of course, impossible. General relativity had made that clear enough back in the twentieth century. However, since…

I am not enough of a mathematician to be able to judge either the well-foundedness or the limits of relativity in physics.

— Pierre Teilhard de Chardin

“Since the mathematicians have grabbed hold of the theory of relativity, I myself no longer understand it.”
