Time and energy, like position and momentum, are two sides of the same coin. The more you know about one, the less you know about the other. (through e=mc^2, matter and energy are mere manifestations of one another)
The uncertainty of T x the uncertainty of E is greater than or equal to Planck's Constant(h) over 2pi(2 x 3.14)
Am I a quantum physicist? No. But I did sleep at a Holiday Inn last night!
