I'm currently going for my Master's in math (bachelors in applied math) but while applying I had to make the choice between math and computer engineering. I went ahead and chose math because when looking at job postings it seemed like it was an acceptable degree for several of them. Almost...

Have you looked into computational science? It uses tools from math, computer science, and physical sciences to solve and model problems. Some schools call it scientific computing. There are also degrees in things like computation physics, computational mathematics, computational biology...

Hello. The university I attend allows you to challenge some courses for grad school. Two of them are Real Analysis I and Real Analysis II. This made me consider trying it. The cost of the challenge test is the same as the cost if you took the course so it really has to count. I wanted to...

For those who have read Halmos, in Section 6 Ordered Pairs (page 23 in my book), he gives a non-trivial exercise to find an intrinsic characterization of those sets of subsets of A that correspond to some order in A. I'm curious what that characterization is. A is suppose to be a quadruple...

I was wondering if universal algebra had any applications in physics. I've done some searches and people have mentioned uses in theoretical computer science but how about in any branch of physics?

What I was thinking that something had to cancel so that I can integrate the function. I haven't worked with the gamma function so I'm not sure about some things. So the \Gamma(n) = ∫ sn-1 e-s ds. So we get ∫\frac{λ^{n}s^{n-1}e^{-λs}}{∫s^{n-1}e^{-s}ds}ds Would the sn-1 in the numerator...

So think I got it. First to make things easier I'm just going to call \frac{1}{θ} = λ So.. ∫^{nx}_{0} \frac{λ^{n} s^{n-1} e^{-λs}}{\Gamma (n)} ds where the sn-1 cancel out right? ∫^{nx}_{0} λn e-λs + s ds after working with the e-s in the denominator of the integrand. ∫^{nx}_{0}...

I'm sorry but I'm still not getting it. I understand about the erlang distribution and after plugging in what should be the parameters for it from (\frac{λ}{λ - t})n I get ∫^{nx}_{0}\frac{s^{n-1} e^{-\frac{s}{θ}}}{θ^n \Gamma (n)} where \Gamma(n) = ∫^{∞}_{0} sn-1 e-s ds I'm...

Homework Statement Let X1, X2,...,Xn be a random sample from the exponential distribution with mean θ and \overline{X} = \sum^{n}_{i = 1}X_i Show that \overline{X} ~ Gamma(n, \frac{n}{θ}) Homework Equations θ = \frac{1}{λ} MGF Exponential Distribution = \frac{λ}{λ - t} MGF Gamma...

Hello, I've started a MS in mathematics at my university and I'm interested in mathematical physics or going to to physics for a PhD. The classes required for the MS are 2 semesters of real analysis, linear algebra, and one semester of algebra, everything else is up to the student to pick and...

Hello everyone. I started a master's in mathematics this semester and I'm worried I'm not excited about as much as I thought I would be. I double majored in physics and mathematics for my BS and now I think I miss the physics. I wanted to do a MS in mathematics and then go back to physics for...

What is everyone's opinion on MOOCs (Massive Online Open Courses), those free online courses that anyone can sign up for. Some offer certificates, do you think they are worth doing to put on a resume? Do they hold any value? Do you think they could be taken into consideration when applying...

Hi everyone. So the delta-epsilon proof to show that x2 is continuous goes a little like: |f(x) - f(xo)| = |x2 - xo2| = |x - xo| |x + xo|. Here you want to bound the term |x + xo| = |x| + |xo| by taking |x| = |x - xo + xo| = |x - xo| + |xo|. Here you're suppose to take δ = 1 while |x - xo|...

Hi everyone, I've been looking at some programs for medical physics and I'm some what interested in computational medicine so I was wondering if these two fields every unit? Is it possible to research computational medicine as a medical physicist? From what I've read they mostly deal with...

I think applied math but take some pure math courses. I'm a math major who has taken computer science courses and noticed that a lot of useful stuff for algorithm development show up in pure math courses. We touched on those topics in the computer science courses but not like we did in the...
