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.
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?
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.
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?
