That's good to hear about MN. And, yes, pay is terrible in TX especially for how hot some of these jobs are. IBEW does exist there, but my experience is that most people in TX just…

I'll second this with the following anecdote. A few years ago, I completed an electrician certificate program at a community college in Texas. I wasn't exactly looking to switch ca…

Money absolutely has an impact across easily available metrics. For example, money lets one purchase better coaching for sports or join a travel team. As we see from the lawsuit, a…

My continued assertion is that "hard data" can be misleading, wrong, and discriminatory. It requires judgement to understand what it tells us and whether there is error in the coll…

Thankfully, I also work in the adult world and this world requires judgement. As an example, my wife is a physician. She and her colleagues use metrics to help assess a patient, bu…

I still contend strongly that it is wrong to distill a person into a collection of numbers. They are not. My mother was a special ed teacher who eventually became a diagnostician w…

There's a wonderful exchange in the movie Interstellar that speaks to this: Cooper: You're ruling my son out for college now? The kid's fifteen. Principal: Tom's score simply isn't…

It's a combination of factors. Rural hospitals and clinics tend to be under-resourced with lack of equipment in buildings that aren't particularly nice. As far as small town, if yo…

There's a video as to how the match works here: https://www.nrmp.org/intro-to-the-match/how-matching-algorit... Basically, you interview at a bunch of programs and then rank them. …

If they don't match, they're allowed to scramble and move into one of those programs with open positions. If they don't choose to, that's on them, but it's still not a problem with…

That's not true. You can look at the residency match for 2025 here: https://www.nrmp.org/match-data/2025/05/results-and-data-202... While many specialties are fully filled, we need…

No, they are not paid too much. There's a lot of incorrect assertions here, so it'll take a lot to work through them. Physician pay depends on specialty, but it can range from the …

I'm an applied mathematician and this is the most common layout for dense matrices due to BLAS and LAPACK. Note, many of these routines have a flag to denote when working with a tr…

Automatic differentiation was actively and continuously used in some communities for the last 40 years. Louis Rall has an entire book about it published in 1981. One of the more po…

That's not true. Here's an abbreviated list from: http://historyguy.com/major_wars_19th_century.htm I'm sure there are others. It lists: Greek War of Independence (1821-1832) Frenc…

True. That said, I'll also mention that tomography is a very rich, interesting field that's still open to new innovations. I work in the area and unfortunately needed to pass on a …

I believe Absil, Mahony, and Sepulchre also have a book on optimization over manifolds: https://press.princeton.edu/absil I was unaware of the Bournal work, so thanks for that. Do …

In the U.S., there is typically a separation between calculus and real analysis. Though, the amount of difference between the two depends on the university. In calculus, there is m…

Laugh. Probably! I gave a talk at that conference titled, "Software Abstractions for Matrix-Free PDE Optimization with Cone Constraints." I still work in the field, so you want to …

Honestly, the parent is pretty accurate. No one is claiming that P = NP. However, the technology to solved mixed integer programs has improved dramatically over the last 30 years a…

I'll second this. Their methods are very powerful and very fast. For those out of the loop, the Chebyshev (and ultra-spherical) machinery allows a very accurate (machine precision)…

A convex function is a function that is bowl shaped such a parabola, `x^2`. If you take two points and connect them with a straight line, then Jensen's inequality tells you that th…

If anyone is interested in safely preserving food, the USDA provides the USDA's Complete Guide to Home Canning, which has recipes and canning guidance when using a pressure canner.…

Outside of the other suggestions in this thread, this book may also be helpful to someone interested in studying applied mathematics in college, but unsure of what that means eithe…

What's your convergence metric? It looks like x_sol gives a residual on the order of 1e-7. That's fine, but I'd like to measure an equivalent number to the benchmark.
