oks in commuting coordinates, (T, x`)(21, 26]. We can mention that one reason to suppose this is the physical choice is that there is a basis in the Hilbert space for a free relativistic particle in which x' and T are both sharply defined, while is there is no basis that simultaneously diagonalizes t an

s about how the principle of the relativity of inertial frames can be made consistent with the existence of a minimal length scale, taken to be the Planck length, Ip[1, 2, 3]. It may also be seen as making possible a maximum momenta for an individual particle. Over the almost decade since it was first

return to the university and find that they are required to learn at the feet of a woman?" In a retort that eternally reinforced my admiration for Hilbert, beyond that for his remarkable talent as a mathematician, he replied, 1 do not see that the sex of the candidate is an argument against her ad- mi

k had helped pioneer the quantum revolution by resolving the paradox of the spectrum of radiation emitted by atomic systems. So it was fitting that Planck should indirectly help resolve the paradoxical makeup of the nucleus. While he didn't himself spearhead the relevant research, he recognized the ta
