Yes, the OP states a good question. My thought, going back some years, is that in some fields engineers work with strength of materials, e.g., what a steel I-beam will hold, and more generally work with, assemble, combine components wit

A big point is: (1) As an employee X, the employer knows how much X is making and will try to keep that down, while (2) a person X who owns their own business that happens to be a good business can just rake in the money with nearly no one

Part II If you do much with computer graphics you will encounter matrix theory. That takes you into linear algebra ; next to calculus it is likely the most useful math. Evidence: There are a lot of downloads of LINPACK. Can start a cour

Part I How to get good with math? Okay. Been there. Done that. Learned a lot of it. Got a Ph.D. in it. Taught it. Applied it. Published peer-reviewed original research in it. Had a good career applying it. Am using it as an advantag

Yes, I considered justifying the impossibility of writing a TeX to HTML converter by saying that TeX was Turing complete and HTML was not. Yup, I considered doing that! Then I just made a simpler and less technical claim!

WOW! Thanks. Will try that.

A laptop for software development or ANY serious work? No thanks. Instead I want a better keyboard, video display, and processor and want room for several disk drives, provision for more peripheral devices, etc. And I'm currently

So, from the OP NYT article, Covid is causing the schools and student learning to suffer. I question if the suffering is necessary: For Covid, I'm old enough to be at risk of death if I got Covid, but I've had both shots of the Mo

I'll add a fast guess from some earlier, solid experiences: Let R be the set of real numbers and n a positive integer. Consider R^n, the common n-dimensional space. Assume this R n is Euclidean , that is, has the usual inner produc

Generally, I agree with the OP. From my experience, some of the claims seem right on target. There are a lot of claims in the OP, and I can't agree with all of them. I would add: In my experience, there is a small fraction of parents

I'm not sure just where the tuition came from. I was a TA for some of the time, but the duties were trivial. At one point a department prof confessed that the department had a lot more tuition scholarships than qualified grad stu

Lessons from my Ph.D.: (1) Role of Math. In most fields of research, the most respected research mathematizes the field, that is, makes progress with math techniques and results. So for Ph.D. research, try to have math play that role. (

(1) Financial Math. Some of the comments here have to do with mathematical finance , e.g., the Black-Scholes model. Mathematical finance done with theorems and proofs has some strong prerequisites of measure theory with sigma algebras,

What I have seen so far for statistical mechanics is uses of integral calculus notation that has nothing to do with anything in any version of calculus, advanced calculus, measure theory, the Riemann integral, Lebesgue integration, etc.

Right. What I described is "not the norm". Are we supposed to consider only what is "the norm"? Instead of "the norm", I took the subject to be essentially how to get a US computer science Ph.D. and gave some

That's an elaborate analysis of the considerations of getting a US Ph.D. Gee, I got a Ph.D. in applied math; it could have been called computer science. But I never went through even 10% of that analysis. I didn't get accepted t
