How quickly do you think stopping the sanctions would bring the energy prices down? Russia already stopped gas exports to several countries.

In university I learned about the simplex method which can be applied to linear programming. I don't know if it's used by modern solvers.

I did software engineering for 3 years after graduation. Now I teach mathematics in a high school since '20. Software engineering was very stressful for me and I also wanted to sync holidays with my kids. Parents seem to value my background. Pay is low but I have a reasonable amount of extra time to tinker.

QR factorization is cool because it is part of QR iteration and you can use it to find all zeros of a polynomial at once.

Solutions to differential equations belong to infinite dimensional function spaces unless discretized.

I don't understand, there were over 50k non-covid deaths in the twice vaccinated and around 500 covid deaths. That sounds significant, or is it due to the age distribution of twice vaccinated?

I think in the past journals prohibiting the use of preprint archives was more common.

How are the theories incompatible? My basic understanding is that GR describes how the space looks like and Standard Model describes fields defined in this space.

I would guess that it is much more dangerous to modify a modern car because they utilize nontrivial shell geometry to improve the rigidity or to reduce weight. When I was attending driving lessons, my teacher claimed that the specific shape of the windscreen or rear window was a very important safety feature in the scenario that the car rolls over.

I think variational problems are more naturally understood through energy minimization. You start with the energy of the system and try to minimize it via derivatives. Then you arrive at a variational problem. The differential equation is then more of an afterthought.

Finite differences are simple in cubes and domains that can be mapped to one. Not so much in an arbitrary tetrahedral mesh.

As a teacher, I'd like to use this in presentation slides, i.e. pause the output at specific times and continue only after a button is pressed. Does anyone know if there exists a tool, e.g., to automatically pause MP4 playback at specific times?

I cannot understand what you are implying. Can you be more specific?

Why is that?
