Not only is it too low, but it is the discontinuity in support. This leads to perverse incentives where for the wage you could make, you’d barely clear the threshold to lose benefits and make barely more money than on government support. Th

Things may get more expensive, but if more Americans can live a middle class life even accounting for the inflation of consumer goods I think that is a good tradeoff.

There is a joke in applied mathematics that we’re like Taco Bell. We all use the same six ingredients, mixing them in different ways. For myself, I’ve found several techniques I use over and over again. Some of this is a “when you’re a hamm

When I was working with NREL back in 2017, they were thinking about coordinating water heater electricity use with a “smart grid.” Each device attached to the smart grid would measure the electricity spot price and would “store” energy to m

If you want to start cutting money from the budget, cut the things that are the: defense spending. There is just so much waste defense procurement.

I concur. As a postdoc for many years adjacent to this work, I was similarly unimpressed. The best part about PINNs is that since there are so many parameters to tune, you can get several papers out of the same problem. Then these researche

I taught numerical linear algebra in grad school and was really frustrated that even the applied math department took so long to build up to solving linear systems and eigen-decompsotions. The ordering of the material in the textbook is gre

The first space shuttle prototype (Enterprise) started construction in 1974. The first shuttle launched in 1981. To the best of my knowledge, there were no major upgrades to the design over its career, save avionics. So even though the spac

It would be great if that tool existed, but it doesn’t seem to right now. I can appreciate the instinct to improve packaging, but from an occasional Python developer’s perspective things are getting worse. I published a few packages before

As someone who works in numerical optimization, this is a dirty little secret of our profession. The optimization algorithms in the literature are great at finding local minima, but often are very sensitive to the initialization as to how s

Once I was working on a government funded small business grant trying to do something that was mathematically impossible (and literally the first example of intractability in textbooks of the field). The only goal was for the company to col

Many of the algorithms in BLAS are not easily parallelized. For example, a QR factorization an inherently sequential algorithm. Optimizing BLAS performance comes mainly from rewriting the sequential algorithm into larger blocks so as to eff

This is a nice exposition, but it would have been more clear if they laid out the difference between inertial and gravitational masses. So far, these two varieties of mass are equivalent in all our observations, but they need not be so. Neg

For reference, a typical adjunct (non tenure track instructor) will make $5000 per course per semester with no benefits. Tenured and tenure track faculty in STEM are typically paid around $60-120k per year with benefits and will teach, at m

I've adapted the same work flow as well. It's really nice to have one script that generates data (often taking a few minutes or hours) and then another (in TeX) that configures display. That way when I recycle plots from papers in

Only on a short term basis. As the snow is melting, this creates a large number of small, shallow ponds where mosquitoes can breed without being eaten by fish. As the year progresses, these ponds dry up, reducing habitat to those permanent

There’s plenty of precedent for corruption with respect to tax incentives, see, e.g., what Foxconn did in Wisconsin: https://www.theverge.com/21507966/foxconn-empty-factories-wi... https://en.wikipedia.org&#

I'd also add C. T. Kelley's "Iterative Methods for Optimization" for more non convex theory. Nemirovski also has a variety of books and course notes that are available, but I haven't spent as much time with them. I

Most police departments have internal affairs departments, but these are largely toothless. I would not expect a national organization to perform much better. The incentives simply are not aligned: it is easy to see a politician leaning on

I frankly blame funding institutions like the NIH and the NSF for this situation. They readily fund lots of cheap graduate students rather than pay for experienced techs. This leads to the glut of PhDs even in fields where there are jobs o

There are many perverse incentives in this system, but one that tends to be overlooked is the incentive for faculty to publish in predatory journals. It's not that most want to publish there, but when even 3rd tier schools require the
