never underestimate the power of the right motivation. i hated coding in school but have now spent hours learning it for 1) downloading illegal sims packs and 2) calculating ao3 wrapped from my fic history

the nspire is actually driving me insane i hate this thing

[obscurecurse]

delirious in DFW airport, flight delayed, searching up what it would take for me to tack on an extra degree in "architectural engineering" (which is different than bs.arch/m.arch) because i am soooo arrogant and i have not had enough apparently. on some santiago calatrava shit

hm yknow its odd that music is brought up pretty rarely as smth akechi might end up doing post canon. within canon he actively knows and cares about music theory, to the extent of calling joker to infodump about it and getting embarrassed when he realizes it. he's also canonically good at math, which is relevant to music theory as well

once again furious at how AI has been implemented and fucking. hyped up and goddamn bullshit. the way its being used to steal creative works and fuck with artists and create porn of real people is fucking NASTY. but god fucking damnit it could be so useful. fucking. ai voice reader for my stupid incomprehensible textbooks where the voice isn't datamined against the person's will. ai npcs that didn't steal their fucking data. ai routine builders that can learn a person's typical day and preferences and help build checklists for people who struggle w tasks. they could be SO USEFUL. but no. no. we can't have useful things. improving lives??? nahhhhhh we've gotta make Pretty Pictures and Steal Fucking Everything to do it

with rotational artificial gravity it appears, from a maths and chalkboard engineering perspective, that there are exponential benefits for increasing diameter up to a point. it does seem to be a go big or go home situation.

there are two basic reasons for this - the first is that as you increase radius you increase circumference by a commensurate amount. for a torus, the area of the circle described here is inconsequential - it should only be filled with the struts etc connecting the centrepoint to the circumference. mostly empty space. your circumference is your living space. This is also true for a cylinder, where the habitable space is the interior surface of a cylinder and the "area" is mostly empty air.

the second is that you can decrees the necessary rotation speed to generate the desired "gravity" considerably. Basically, you spin a 1 kilometre torus slower than a 10m torus to get the same "gravity" pulling you away from the centre point.

This is desirable because it reduces the Coriolis force, which results in two big problems for rotational gravity. the first and most obvious is that falling objects follow a curved path, the higher the force the more extreme the curve. the second is that it affects your inner ear - i forget the number right now but we know about how many rpm a human can tolerate before their inner ear causes significant disorientation and continuous vomiting, I believe it is 2 rpm?

the issue is that the bigger it is, the larger the forces involved, which leads to significant issues of sheering and means that failures become more catastrophic. I wish I had the maths in front of me but this generally leads to a diametre of about 1km being the sweet spot, iirc.

Is there any point you think I'd like to have a go again? Why are you happy just testing? My role is completely changed now. Like I said, I'm not looking for those fine little details that are out there and comparing things. I suppose, I'm not an engineer, but I'm taking the role of an engineer as a test rider, because a lot test riders have careers where they want to achieve things and move forward, but I'm interested in each step, what it does, why it does it. I really want to see this go further forward and take it to another level. So I'm going to start learning all I can from these guys to get a better understanding, because there's a lot of complicated systems. You might be an engineer soon? Probably not a full time engineer, but if I wasn't going to race years ago, something that I wanted to do is get an engineering degree. So it would be nice to learn a lot more from these guys.
