I've worked on Ising model, bioinformative, complex network, random walk, percolation, pattern formation, bose einstein condensate and quantum optics. Now I'm settling down and hoping to gain some expertise.

comment Time for a particle undergoing brownian motion to reach a point in a volume
@alarge Exact solution might be possible for special configuration, say the sink in the middle, I think. However, in general, the exact shape boundary is not quite important. It is usually solved by approximation. With a quick search, the closest results are 2D, but not 3D journals.aps.org/pre/abstract/10.1103/PhysRevE.83.021919

comment What is the largest number of bosons placed in a BEC?
It should be the highest one for atomic BEC, but if you also count for other quasi-particle BEC, it should be even higher.

comment The Delta-Function Potential
To clarify, for bound state, it should be $E<V(\pm \infty)$, which is just happen to be zero in this case.

comment How does a steady wind flow generate sound?
@honeste_vivere Thickness of a paper is usually 0.1mm. Sharpness usually depends on context and a comparing to something. In the situation here, it is related to the thickness, air flow speed
