I’m probably starting an argument by replying to a faculty listserv thread about “good” uses of #AI with estimates of the environmental costs of AI usage:

  • Having a single 10-50 question text conversation uses about as much energy as charging a smartphone [1]
  • Generating a single image uses about 500 mL freshwater [2]

Free things always have a cost. We should ask ourselves who is paying

Does anybody know if there’s a traditional composite material that behaves something like fibreglass? As in fibre/fabric laid up in a binder of some sort to make a stiff material in arbitrary forms.

Paper mache is one but it’s too weak (I think, maybe there's a super version?). I'm considering things like cotton or flax in casein glue or pine resin... but I doubt it will work.

(And my last casein glue experiment stunk like rotten milk for weeks!)

As a gift for me this birthday weekend:

Tell me in as many words as you can about something you wholeheartedly, unreservedly love and/or enjoy. Paint me a picture. Leave out any apologies, buts, or "in spite of"s. Just love the thing out loud, and let me love it with you.

@mishellbaker I love taking care of the wild black raspberries around my house. It’s sort of foraging and sort of gardening. I’ve trimmed and trained the brambles somewhat to encourage them to grow along the edge of my porch, but when it’s time to harvest the berries, it’s always a little bit of adventure to get them from the thorny thicket. I love to watch their progress from new growth to blossoms to ripened fruit. There’s such anticipation for the first sweet berries!

Have we decided yet what the appropriate gender-neutral substitute for sir/ma’am is? Because especially when I’m back in Georgia (maybe I regress to being ten years old) I sir/ma’am service workers constantly out of habit.

#BlackMastodon only:

The debate about whether parents should or should not spend time educating their kids after school, or if that's the school's job, has strong opinions all around.

I don't judge any opinions on the spectrum, because I know that those that feel like "it's the school's job" say so more out of the reality of time constraints of surviving US racism as an underpaid Black person, and I know that Black parents are more likely to help their kids with homework.

And... 2 Sigma🤷🏿‍♂️

This from @JuliusGoat is closely related to what I was thinking when I first heard the Access Hollywood tape:
https://mastodon.social/@JuliusGoat/111120967530237977

Bullies, abusers, all these gross people are constantly testing the waters — to see what they can get away with, and also to see •who• will let them get away with it. It’s about looking for targets, and it’s also about social group formation.

@inthehands An important tool in my bystander toolbox is one I learned from someone on Twitter a few years ago: say Wow.

Someone says/does something racist/sexist/fascist/ableist/etc? Say “Wow.”

It interrupts and draws attention. It treats whatever came before as out of the ordinary. It doesn’t support the other person, but it also doesn’t immediately make them defensive. It buys you time to figure out what to say/do next

@DrFerrous I was down about 10% of my class yesterday. I heard that COVID is going around one of the dorms, so I emailed folks to encourage them to get tested, stay home if positive/symptomatic, and wear masks. I got at least two responses from students who are now COVID positive
I often feel like the #LastMaskStanding but maybe I’ll convince more folks to #MaskUp.

I think the first time that I realized adults will repeat outright baseless claims without stopping to think how illogical and silly they sound is when the whole "Video games make children violent" arguments started bubbling up. Like, I recall losing it on multiple teachers between 6th grade and 12th grade over this lol.

@belehaa@wandering.shop avatar

@ReneeWestberry @skua @vincent @anubis2814 @BlackAzizAnansi There is a whole history of folks insisting “this is fine, don’t worry” when they know it isn’t so. Another example: the inventor of leaded gasoline poured it over his hands and inhaled the vapors at a press conference to show it was safe. He’d already tried curing his own lead poisoning the prior year

we just ended our cornfest 2023. Our total ears of brought to the table from the this season was 197. This is not bad but our third planting ended up a little disappointing because I did not manage to feed the last row of corn enough for a variety of reasons, but lesson is learned for next year! (If I count the 4 ears the squirrels stole we grew 201 ears) Oh, yes, we also have several tons of (lost count)

@levampyre @richrollgardener My family freezes sweetcorn. Cook the ears as usual, then cut off from the cob when it’s cool enough to handle. Freeze in quart bags on sheet pans so they lay flat and are stackable later. Not quite as good as fresh from the field, but worlds better than a bag from the store
(I just wish I had an effective freezer container that didn’t involve single use plastics)

@Drdonnayates @academicchatter If some applicants don’t meet these expectations because they don’t know they exist, and if they won’t learn about these norms and expectations unless someone tells them, then how equitable is your hiring process? Who will have had the advantages of good mentorship & advice? Who will be left out?

I sympathize with your frustration, but it sounds like a case of #HiddenCurriculum to me

@christinkallama @histodons The supposed “demographic cliff” has been used to justify cuts at several other institutions already, and it’s built on shoddy racist assumptions about who can/will/should go to college (see for example https://lareviewofbooks.org/article/demographic-realism-and-the-crisis-of-higher-education/)

If you ever hear an administrator assert that the demographic cliff is coming, make them show their work!

I signed up for AP Chem in HS, because I loved math and did great in AP Physics.

It was a disaster.

The teacher was this creepy man who ignored my questions. All the students in the class had outside tutors and my mom was like "if you think you need a tutor take the regular science class" -- I could not make heads or tails of the homework. I lasted two weeks then transferred to Statistics and got teased all year for taking two math classes. (I would have cheerfully taken 3)

@futurebird You might like Calculations in Chemistry (Bookshop link: https://bookshop.org/p/books/calculations-in-chemistry-an-introduction-donald-j-dahm/11195240, currently back ordered there, available on Amazon)

The book is intended to make the mathy parts of chemistry easier for folks who struggle with math, but maybe that math-chem link would be helpful to you to go the other way & understand the chemistry that uses that math

I teach intro college chem and have used this book as a reference

When you do your "Oppenheimer calculus," and are justifying the dropping of the bomb because it "saved more lives than it cost," remember to factor in the creation of the Congo crisis (100K dead in under 4 years), and the assassination of Patrice Lumumba.

Where did the Uranium come from? And how did the US ensure that neither the Germans or the Russians would get any?

(Answers: The Congo. By eliminating Lumumba)

@mekkaokereke It’s also worth asking where the rest of the ore went. When they pulled uranium from the earth it was mixed in with lots of other material. It had to be refined, and a lot of that early refining work was done near St. Louis, Missouri. They threw the waste “away,” but there is no away; everything must go somewhere. In this case “away” was a landfill near a creek. Now it’s a cancer cluster
