HRT does not help with scarring or issues caused by scarring. Lots of other things sure, but not scarring, which is what the article claims is the problem.

Its mostly a question of pr I think. More highly trained troops are less likely to die or mess up, and that is bad pr. So we train them more, but if that training also causes deaths, which becomes bad pr, we will train them less. Younger less trained soldiers are cheaper too, so I think the tradeoff will favor less training as soon as this becomes common knowledge anyways.

The only usable EMPs we have are nuclear weapons. So if you are willing to use one, then just detonate it a bit closer to the surface and it will work just as well against everything we have.

You say that suicide hotlines are more for the friends of people at risk, than the people at risk, as if it is a bad thing. We as a society generally dont know how to help people who consider suicide for its myriad of causes. We do know how to help their friends though, and pretending that there is help to be had is a big part of it.

A .45 gunshot feels like a sound, and with hearing protections at a few meters you hear it but cant feel it in the slightest. You feel it in your hand but not further. Artillery is more similar to how it feels standing next to gigantic speakers at a concert, even with hearing protections you feel it throughout your entire body, except sharper.

My bet is on a high threshold. There is no evidence for this at all in small arms enthusiasts.

If this is accurate there is likely very little to be done, and the solution will likely be to have less training and retire a decade sooner.

If I understood it right, its firing artillery, not rifles. Even then I doubt cavitation, but not shock echos at density borders tearing he tissues at the border.

The bash code which creates the c file which gets the list of null terminated files in a directory and compiles it, and runs it, is easier to write and understand. Bash is a lousy language to do anything in, python is almost always available, and if not, then CC is.

Yes. The higher derivates are useful in many cases, both as sought properties and observations. The invariances implied by relativity,(the trivial notion that the universe behaves the same regardless of where you select the center), mean that most laws are defined on the second derivative. Taylor approximations are useful to approximate something locally, but properties of the system over wider regions generally need to account for the higher derivatives. You can see this in e.g. simulating a system over time requires that the derivatives at the borders of the valid taylor approximation region to be included as diracs.

Or in other words, you can approximate exp(x) as a set of first order taylor approximations that each covers a small window to arbitrary precision, but the combination of them is still has well defined higher derivatives that are not 0.

Why bother with giving words for something which is longer than their mathemathical definition? The word can be unknown, but if the function is unknown the word is useless?

But all of them are based on courses that define nth derivative, and the notion of continuous vs non continuous functions. What is the value of giving them names instead of just using nth derivative?

What value is gained from using these terms over just saying nth derivative?

Will do

It would be amazing. Willing test subjects and the competitions to actually tell if we are making improvements.
