Can someone please explain why the van der Waals force is attractive instead of repulsive? My understanding is that is has to do with the electron cloud creating a dipole, but I can't seem to understand why the force isn't repulsive (since like charges repel.)

I know that when I'm solving a linear equation of the form ax = b (mod n), the gcd(a,n) tells me how many solutions there are. I don't really understand why this is. More than a proof, I'm interested in an explanation that will help me understand the relation between the gcd and number of solutions. Also, why does the ... | 1 |
I'm trying to wrap my head around function spaces.

I'm currently learning about local extrema in serveral variables and have come across the second derivative test for classifying critical points of multivariable functions.

Wikipedia's page for Imperial Units does not list Fahrenheit. The corresponding page for SI Units lists Kelvin as an SI unit, and Celsius as a derived SI unit.

Is there a solid rule... | 1 |
At the moment I am following a course on variational methods for mathematicians. Last week we derived the Euler-Lagrange equations for a functional under a constraint. In this derivation we found that the Lagrange multiplier may depend on time. However, I could not remember having ever seen an example of a Lagrange mul... | 1 |
I know that it is technically impossible to reach the speed of light in vacuum since the mass of the object travelling would reach infinity. However in a medium, would there be some sort of theoretical equivalent to a sonic boom that would occur? Since sonic booms are formed when sound waves can't catch up with an obje... | 1 |
I'm writing an essay for medical school applications. Both my parents were physicians, so it is what I was familiar with growing up.

I have been learning more about Hilbert spaces in an effort to better understand quantum mechanics.

My Questions: Why... | 1 |
I've been studying random walks as part of a finance course and I'm starting to become really interested, and I'd like to start a study of them from a mathematics (i.e. more formal/rigorous) point of view.

In Mendelson's book ("Introduction to mathematical logic") he defines truth values for sentences in the propositional calculus using truth tables.

Does it sound right to say "be successful" instead of "good luck" as a quick reply? For instance: A : I have a tough exam tomorrow. B : I hope you'll be successful in your exam.
