I have always thought this was funny.
Richard Feynman, the character that he was, took the time to figure out that Element 137 on the periodic table of elements, would be the highest element that could be produced. This because at that atomic number, the atom would have an electron on the first level, that would be travelling faster than the speed of light.
Light speed being a constant, not a law, we would then have to consider such an element as existing only partly in our reference frame.
