    Completely rewrite the curriculum and problem sets for my advisor’s grad-level course for flipped-classroom virtual teaching as opposed to in-person lectures. It was the pits for many reasons, not the least of which was that his attitude became “everyone is at home doing nothing, so I can ramble into a recording for 3 h instead of giving 1 h lectures and we can have a full problem set every week instead of 4 in a semester and the scheduled class time is now a problem session amd to answer students’ questions :)”.

    And a fuckton of DFT calculations, so honestly, fair.











  • Something something typical US circuits can deliver less power than typical Euro circuits. Not a lot less though.

    I used to own a $15 plastic electric kettle, but it died after a year or two. When I went to target to get a new (hopefully better) one, I realized I could instead buy a plug-in induction plate on sale for $50, and a plain stainless steel kettle that somehow cost only $1.50 (less than the shitty bread that I was also buying? how?). The induction plate was honestly one of the best purchases I’ve made in a long time. Sure, I have to wear earplugs to tolerate the high-pitched scream that the frequency driver makes, but it boils water just as well as an electric kettle and is also soooo much nicer to cook on than the resistive curlicue burners that came with my apartment.

    For those who did a search only to get back pages of less-than-useless SEO slop that just recites the number line, here is something that better describes some of the grammatical insanity.

    also, czterydzieści cztery is imo one of the less pronounceable words (well, two of them) in Polish.


  • I know that this is partially a joke, but I was trying to figure out what kind of lab would be done to produce chloroform that would be appropriate for students (recent OSHA crackdown on chloromethanes notwithstanding)… haloform reaction I suppose? Is that a common teaching lab experiment?


  • My mom took my little brother to participate in a child psych study like this when he was a toddler (mom had some ties to the university). It was a very similar experiment with skittles as the prize. My brother sat staring glumly at the candy the whole time. The test administrator was increasingly enthusastic with praise after each round right up until the end when she congratulated him and said that he could have the whole bag. He said “no thanks” and ran back to mom crying because he was told there would be candy but they only had skittles, which he very much did not like (and for that matter still doesn’t). The administrator was apparently embarrassed and told my mom that she thought that all kids liked skittles…



  • According to my buddy who worked for Dow, part of these “savings” apparently was taking a hatchet to their R&D segment with a bunch of spray-and-pray layoffs (apparently a common happening these days). I realize Dow is mostly commodity chemicals these days which is much more preservative in nature than other segments of the chemical industry, but even so it sounds like they are killing any hope of competing with new technologies and moving to the “squeeze as much as possible out before it goes tits up” stage.
