I just recently got a bunch of medical stuff and psychiatric stuff sorted out after decades of barely being able to function. So I’m finally feeling “normal” and the state of our politics has me stressed to the point of action, but not to the point of curling up in a ball and doing nothing, which is unusual for me. Very surreal to be functional in a nonfunctional world.
Hectic and our teachers are constantly complaining about how kids can’t do basic reading comprehension tasks. Like copy a sentence from the board into their notebook and then repeat it back to you in their own words. There are 13 year olds who cannot do this. There are adults who can’t do this. The majority of Americans read at or below the level of an 11 year old.

Isn’t there a difference between “the most squares fit into a square” and “a collection of squares optimized for maximum small-square area inside of a larger square”? If there’s a difference in solutions, what would the solution for the latter actually be?
Mathematicians halp plz

Tall back pain person here. Gonna try this
Okay so sounds can be broken down into individual tones called sine waves. The math that lets us do this doesn’t care about how tonal or noisy the sound is. It takes arbitrary input. However, human brains and ears (as well as those of many other creatures) seem to optimize for tonality of some type.
The simplified explanation is that we like when the frequencies of the tones that make up a sound are in whole number ratios (the harmonic series). However, there’s a tolerance for frequencies which are close to those ratios but not perfect. And when harmonics don’t fall perfectly within the harmonic series, we can instead prefer intervals between notes which are slightly “out of tune” compared to what the harmonic series would dictate. For instruments like strings and woodwinds where the vibration of the air happens along a more or less straight line, the harmonics tend to be close enough to the harmonic series for this not to matter a ton. But for instruments with different resonant features (bells are a common example), the effects of this are more pronounced.
There is also some math which makes tuning instruments solely to the harmonic series impractical. This combined with the tolerance for consonance I mentioned before has led to a rich sea of different traditions which play around with tuning in different ways. The western tradition alone has a long history with how a twelve note chromatic scale ought to be tuned. It turns out that equally diving the octave into twelve notes just so happens to be a good approximation of a lot of harmonic series intervals, but some intervals are less perfect than others. It’s all a series of compromises.
Dude my dnd campaign is run on Discord what the fuck. Do I need to start hosting open source voice and video chat?
To coordinate that many people, you would need either:
We saw how Covid worked out so I think the likelihood of everyone not only acting at once, but also in unison, because of a disaster is quite small without a party to coordinate. There need to be constraints on behavior with levers of power to pull and enforce those constraints in order to get literally billions of people to do the same thing at the same time. I don’t see a way around it.
