  proper alchemy

• ⁨Comment⁩ on ⁨Nancy Drew⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Man, fuck hetcat. You put extremely rare metals on special rocks in a very particular way just to burn something juuuuuust the right amount. Or un-burn it, I suppose. How does it work? Well, oxygen adatoms react with the substrate bound to a metal nanoparticle on its 10(-67) face following a formation of an oxygen vacancy-- jk, jk, it’s actually all happening at a tellurium defect in your support material you silly goose. Oh wait, nvm, it’s actually iron contamination from manufacturing defects in the walls of your vessel. Git gud. Oh wait nvm it is actually catalyzed by your precious metal, but that metal needs to be slightly poisoned by lead and nickel from the radioactive decay of trace thorium from the welds and cobalt-60 in the steel, respectively. How could you have forgotten?

  To add, labcoats don’t just mitigate splash hazards. When walking around lab and working at the bench, you brush can up againt all kinds of surfaces that, despite people’s best efforts (or less-than-best if in school), may not be perfectly clean. The coat guards against contamination of your skin, yes, but also your other clothing, which may transfer the contamination to skin, eyes, or mouth by inadvertent contact later. I’ve got a sweater with a lovely nitric acid stain (read: a small charred hole) from such a scenario, though tgat was partially due to a poor coat fit.

  Also, I see you premeds. Button up your damn labcoats and do not leave the lab with them on. This ain’t TV.

  My take-home was $1700-2100/mo after taxes and fees depending on whether I was teaching that semester (teaching paid less). We were paid minimum wage (at the time $15/h in CA) on the basis of 8 h/day, 5 days/wk 52 wks/y lmao. Rent split 4 ways was ~$1500 per person, and that was the lowest of anyone I knew. UC Berkeley.

  Phonetic transcription using vaguely English conventions 'cause my IPA keyboard broke:

  Notes:, merged ś/sh, ź/ż/rz; tried to keep readings of a, e, and y somewhat similar to the vowels in father, dell, and ick by doubling the following consonants or ending open syllables with h.

  “Proper” conjugations are not totally settled, especially given its slang nature. Yeet does feel like it might be strong (stem-changing), though there’s really no authority on it. Interestingly, I found on googling that there is a version of the verb yeet stemming from Middle English verb yeten, which has two variations. The first meant “to address with the pronoun ye” (e.g., as opposed to thou) and had weak conjugations (i.e., yeeted/yeted). The other sense refered to pouring or moving liquids and could be either strong or weak (simple past: yet or yote, or yeted; participle: yote, yoten, yeted). So, looking for historical comparisons is also unhelpful.

  I’m more a fan of “that one fused 7 and 6 memebered ring diazacycle that has that guanidine sorta thing going on that people use as a strong base when their molecule is too much of a pussy to handle a real base, shit, the fuck is it called… a oops shit it’s not guanidine, the fuck is the nitrogen version of an ester called, yeah that”, personally.

  Neat, thanks for the clarification. Even though the initial proportion is 50/50 for X-activation, are there scenarios where one daughter line is more prominent than the other, or does it usually remain 50/50?

• ⁨Comment⁩ on ⁨It do be like that⁩ ⁨⁨7⁩ ⁨months⁩ ago⁩:

  This is not true. That women cannot have the congenital dichromacy (or anomalous trichromacy) that biological males commonly have is flat out wrong. A biological female can still be a protan or deutan, but the phenotype requires that both X chromosomes carry the recessive color vision-deficient alleles. Nevertheless, given that ~8% of all X chromosomes have such a gene regardless of sex, the incidence in the female population is still around half a percent, which is not insignificant.

  Interestingly, one form of tetrachromacy in females actually has the same cause of color vision deficiency in some males (specifically anomalous trichromacy). From what I understand, only one X chromosome is active per cone cell, and which one is active is random. So, half of such a person’s cone cells of one type are “normal” while the rest of that type are anomalous and have a slightly different peak wavelength. The net result is four different types of cone cells, i.e., tetrachromacy, which may have an incidence of more than 10% in females.
