    N particles in 2 boxes - distinguishable/indistinguishable - probability association

    Hi there I'm new here, I have this question on my homework that has been bugging me for a couple of days now and I was wondering if anybody could help me out. Let me set the scene. We have N particles in total in a box of volume V. We split the box into V1 and V2 with a probability of p...

    How to prove two methods are “similar”?

    We are testing two imaging machines. One of the machines has been validated numerous times. However, we built the new machine and we need to prove that it is similar/comparable to the validated machine. So, the machines image a certain tube and determine a physical property. With several image...

    Physics Teacher with a question of appropriate use of regression equaitons

    Is it ever acceptable to replace discrete measured values with a continuous function if you are certain you have the right model? For the last week my students have been working on using experimental results and statistical tests as evidence to either accept or refute someone else s or their...

    How to convert two particle bivariate distribution to a single variable distribution

    Hello, In physics when studying identical particles bivariate probability density functions arise that describe the position of each particle. For example if we were looking at the infinite square well (with bounds from 0 to L) and had one particle in the ground state and another in the...
