QUESTIONS: (1) When was the fundamental constant first denoted _h_? And why _h_? What word does h stand for? (I think in classical physics, too, energy x time is "action", but that starts with _a_.) (2) Have there been any announcements of the big celebrations that must surely be planned for the work that marked the transition from classical to modern physics, revolutionized much of science, and laid the foundations of new industries? thanks E.
