uncertainty in Heisenbergs uncertainty principle (urgent)
This might be a stupid question, but i seem to find different versions of this the more i look. I have a big exam tomorrow, and i have a slight problem. The thing is that our textbook says that Heisenberg's uncertainty principle is
dx x dp (larger or equal to) h
dt x dE (larger or equal to) h
looking through my notes, i find
dx x dp (larger or equal to) h/2pie
dt x dE (larger or equal to) h/2pie
and a search on the internet yield more versions, among them:
dx x dp (larger or equal to) h/4pie
dt x dE (larger or equal to) h/4pie
hmm. could someone please try to explain this discrepancy to me. And please hurry, exam tomorrow
Thanks
