I'm interested in knowing more about this, could you provide pointers to more information? I will be moving to the northern hemisphere after finishing my academic duties, and in my possibilities I consider the US, France or Germany. Fr

If I remember correctly, according to Leonard Mlodinow's Feynman's Rainbow , Gell-Mann wrote that in Feynman's obituary for the Physics Review. It "raised quite a few eyebrows".

Numerical solutions of PDE are hardly studied in a typical technical education in calculus (it requires more theoretical machinery) or statistics (PDEs in statistics is somewhat narrow and specialized).

It is easier to study from a theoretical point of view (easier that the heat or the wave equation: [1], Ch. 2), and it's easier to implement a solving method. When you are learning the finite element method, this is one of the first ex

Also, WWII accelerated many discoveries in several areas of mathematics (in America, at least): statistics, optimization, control, numerical analysis. To such an extent, that many of those discoveries are still the main object of study in t

I somehow get a feeling that if the prospects were actually good in any sense, colleges would advertise them whenever they had the chance (is there even reliable information about how salaries are distributed? Not just means and standard de

I think that the (engineering and computing) technology version of the concept may be best exemplified by unix and Fortran/C/C++. At least in my field, Numerical Analysis of PDE, we encounter computationally heavy problems daily,

As usual, the replies are attacking an oversimplication of the concept of the Lindy effect, and that reaction in part may be because Skallas indulges in oversimplification himself. The condition of something being Lindy is something to be d

The term measurable is referring to "measurable functions" in measure theory, which correspond to functions verifying that the pre-image of any measurable set belonging to the sigma-algebra of the codomain belongs to the sigma-alg

While I can't give the exact prerequisites, I know that all of the things that appear in the paper relate to: (1) Linear Algebra (2) Optimization Theory (Convex Analysis, non-convex optimization) [0], [2] (3) Probability Theory and S

This also happened in Chile, although from the article it seems it was not as prevalent as in our neighboring country. (In Spanish) 11 chinese fishing ships spotted in chilean waters, 70 (!!!) of them made it to the Atlantic through the M

I am actually thinking of starting a math blog where I have to use extensive use of mathematical symbols. Using computer modern would also be nice. My idea was to keep the blog as minimalistic as possible, but I have not figured out how to

Leyendo el resto de los comentarios, sigo sin entender porqué habría de ser más difícil aprender de una manera u otra. Estoy de acuerdo con la idea de que sea estándar. En el peor de los casos (si fuera cierto que es más difícil), los emple

As someone who is latin american, I never understood what is the obsession with identity in the US. American hispanics I've talked to use it as something of a catch-all concept, but I've observed that many only have a meagre profi

Curious about your level of mathematics exposure? I remember that maybe in the most basic introduction to higher maths words were coupled with my reasoning, but later on reasoning was wordless (Jacques Hadamard reported something similar).

I remember that in a graduate class the professor told that among the important contributions of the theory was the BS formula. He never told us precisely what you wrote: P/L is in the tails. I wonder if he knew that LTCM went bust, wh

That is a good point. I am on the other side - excessively academic. One thing I've noticed is that understanding something does not equal having working knowledge of it (knowing how to implement it, etc.), a person with a theoretical

Ctrl+F on the words stem, math, science, engineering, major, humanities gives no results or clue about the type of major people are choosing. Considering that it refers to the gender differences when it comes to seeing the value in it (and

Thanks, I'll look it up. The best textbook from which I studied (operators) was Elon Lima's Algebra Linear. Sadly the only physical copies are sold in Brazil.

I understand, I too had a similar experience in high school. My comment was largely referring to my context: This semester I'll finish a mathematical engineering degree (in my country engs. are 12 semesters long) and the abstract way i

In college I was taught Linear Algebra from the operator point of view, rather than with matrices. That way theorems are clearer and the student's understanding is deeper, but for applications it's better to study from the matrix

Reading the comments in this thread, I am surprised to see that many think it lacks math. I am majoring in applied math (all my professors are french-school mathematicians, in a non american university) but I deem my courses excessively the
