" Crypto ' and " Anarchy " today are similar to what these two were back then... The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and  therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into  mere shadows, and only a kind of union of the two will preserve an independent reality. https://en.wikipedia.org/wiki/Hermann_Minkowski
