You want to know what a Mathematical Modeling course covers? Well, here's a sample syllabus for an equivalent course offered at Illinois Tech: https://science.iit.edu/sites/science/files/elements/am/courses/syllabus_math_486_sp12.pdf

Since I don't see a thread for this already, I'm making one. This thread is to post updates in your application process, notably acceptances or waitlists. I applied to SULI at Argonne; they first opened applications up for staff/group review Jan. 26th, and I got an offer in the HEP division...

I took an Intro to CS class too. It was good, but I recommend taking a couple more if you can. My school has two computational physics courses (lower level and upper level) that we have to take. Still, if you're going into theoretical stuff the applied math courses will be useful. Honestly, I...

Math will be good for theoretical physics; but you'll need to model this theory anyway, and for that you'll need experience in programming. Depending on your school, there may be physics/math classes that cover what you need. Me, I'll be getting a math minor but I've been taking CS courses when...

This thread is mainly because I'm legitimately scared for science funding and my career, based on the new POTUS's (lack of a) science policy. One random article I pulled up by searching "Trump science policy" had this ending line: "...In short, a Trump administration would mean a crippled US...

Look into: The Eliashberg-Migdal formalism (basically extended BCS theory), and also Dynamical Mean Field Theory (Kotliar) which has successfully predicted a superconductor (if I recall correctly, it was high-temperature). It's complicated stuff!

You don't have to attend university in order to send a professor an email. I send professors from other schools emails all the time! Whether you go into a chemistry or physics program depends on the schools you're considering (or maybe you've got enough flexibility to attend any number of...

No, of course I wouldn't turn it down! I am fully planning on doing this, I know I would make connections there and learn a whole lot. Brand name doesn't matter to me personally, it was just one example of something I thought could be an impact factor for my future based on my SULI experience...

Hi there PF, Say I get into SULI at Argonne (a current researcher there wants me to be in their group next summer and says it'll be pretty likely I'll get in). The work I do will of course be important, but does the brand name mean anything (to grad schools, employers like Intel/IBM, etc)...

A simple Google search seemed to yield a few papers, one of which is here: https://www.researchgate.net/publication/231076123_Velocity_dependence_of_the_van_der_Waals_force_between_molecules

Just wrote down the start to a solution. Differentiate one of the equations with respect to x. You already have expressions for du/dx and dv/dx, so when you differentiate you can substitute the other equation in. Voila! Suddenly you've got an integro-differential equation for only one function...

My graduate math for physicists course has been using the Frobenius method for ODEs like that. http://mathworld.wolfram.com/FrobeniusMethod.html

The Frobenius method will give you solutions I'm sure, they may be series solutions but I don't know what kind of solution you need. http://mathworld.wolfram.com/FrobeniusMethod.html

1. Yes. Otherwise known as the Van der Waals force. It can occur for neutral molecules/atoms alike. I'm sure you can look up papers or read the Wikipedia page. 2. Yes, these measurements are often done. http://phys.org/news/2016-05-physicists-van-der-waals-individual.html 3. As the above article...

Maybe I'm tired and not thinking straight, but is k_tot really twice the number of edges in the entire graph? If m_0 = 10, then at the beginning any node n_i is connected to 9 edges. Since you have 10 nodes and each at the beginning is connected to 9 edges, k_tot is 9 * 10 = 90. Then k_tot is 10...
