    Undergrad What is the mathematical topic related to finding gaps in a sequential list?

    If I have a sequence 1,2,3,.. 1000. I can find a gap by summing up and subtrating from the sum of 1.. 1000 (usually with a known formula like n x (n+1) / 2 but with processing power I can just add 1 ... 1000 with a computer program). If there is a two number gap, I can add squares as well and...

    Graduate Why do precise hydrogen atom energy eigenvalues not violate the uncertainty principle?

    If the energy Eigen values for hydrogen atom can be precisely determined, does that not violate uncertainty? Since DeltaE is 0 in this case as energy (and therefore momentum) is known exactly?
