I really like math and I want to major in it. I want to hopefully get a masters in math. But I want to know what is it like? Do any of you here have a masters or at least have an idea of the course? I heard getting a masters is a lot of independent research. How is that different from a...

So I was wondering what mathematics I will need under my belt before starting at a brand name graduate school(MIT, UChicago, UC Berkely, CalTech, Harcard, etc...) if I were going to specialize in particle or soft-matter physics. Thank you!

This is Dr. Stephen Marquadt. http://img404.imageshack.us/img404/1373/stephenmarquardt.jpg When he was a young child, his mother was horribly disfigured in a car crash. So he eventually took the route of becoming a reconstructive plastic surgeon. As a plastic surgeon, he had to work out...

Due to personal life issues and limitations, I've been seeking other options for my B.S. and came upon Applied Mathematics. What I've been on the fence about for a while now has been which Engineering degree to pursue be it Material Science, Mechanical, or Aerospace. However, it has been...

I'm trying to write down an axiomatic development of most of mathematics, and I'm wondering whether it's logically permissible to use natural numbers as subscripts before they have been defined in terms of the Peano Axioms. For instance... the idea of function is used in the Peano axioms...

I decided to post a new thread for this. I saw the pinned thread about going into Engineering but my specific questions were not answered in that thread. I am going into Aerospace Engineering this summer. I am doing it because I love Physics, like Math, and am very interested in Spacecraft...

Could anyone tell me what is the mathematics of the 2D and 3D mesh? Thank you

When you solve an equation, how does it make you feel? Why do you open a book and solve every equation in it? After doing so what do you feel? I don't think solving maths problems can release adrenaline so how does it make you feel? Why do you guys continue to pursue maths? Do you get comfort...

I am curious about the note taking strategies implemented by others on this board. I am referring to notes taken while reading (as opposed to notes taken during a lecture). As I progress further in my studies, I am noticing that I learn the material best when my notes become somewhat of a...

Here is my situation: I am currently finishing my undergraduate physics program and thinking of doing graduate studies. My only concern is that the knowledge of mathematics is fairly weak. My program offers little mathematics, its very general physica. I am interested in doing theoretical...

mathematics - Q 8 -- Forming Differential Equations

Homework Statement I have not been doing Lyapunov for a while and when doing an ordinary Lyapunov problem the other day, I ran into a funny situation. The correct way of doing it: \begin{align} \dot{e} &= \frac{1}{L}(u - R(e + x_{ref})) \\ V(e) &= \frac{1}{2}Le^2 \\ \dot{V} &= Le\dot{e} = Le...

Hi everyone, I've set up my schedule through the next three years so that I will be able to graduate with a double major in mathematics, and economics (both bachelor of science). I was just wondering if anyone knew the job outlook on these two degrees. I have a strong interest in both...

For a mathematician, how is rotation defined in the most general sense? Question arose to me because it occurred to me that an essential property of the rotation matrix is that it preserves lengths. Is this the only mapping (if not please give me a counterexample) that has this property...
