I strongly disagree that memorization is important or foundational to advanced math. It definitely is useful, but you don’t need it. And the more advanced your math gets, the less valuable it becomes.
My experience is that university-level math explicitly tells you to not memorize values and formulas, but to get comfortable finding solutions directly, because then you actually learn what is going on and have methods that are universally useful.
In the real world memorization is even less useful. You will never be as fast and accurate as a calculator, or remember as many values as a precomputed table has. So why bother?









This is an event that takes privacy very seriously, where it’s not uncommon for speakers to present evidence of crimes, and where a large antifa-flag hangs over the entrance. I think they’ll be fine.
The other two on stage where journalists, and while I’m not familiar with German law, that likely limits the police’s ability to try to get to Root through them.
If reasonable precations were taken, there will not be any evidence directly tying the person on stage to the crime, and even if there was, them being in costume leaves a lot of room for reasonable doubt about who it actually was.
