In fluent speech, the conjunction (the first “that”) is unstressed, and as a result some speakers reduce the vowel a bit toward schwa. However, if you told those speakers to carefully pronounce each word, I bet they would pronounce the conjunction and the pronoun the exact same same. A more common example of this kind of reduction is the word “to”, which is almost always reduced to /tə/ ([tə] ~ [tʊ] ~ [ɾə] depending on dialect and surrounding words) in everyday speech when unstressed.

Fun fact, you can reduce just about every unstressed vowel in English to schwa (if it’s not already a schwa) and still be largely understood.

dass das das das dass da ersetzen kann ist falsch

translation: that “das” can replace “dass” there is wrong.

same shit different barbarians

Related: spicy foods. I used to be basically intolerant of it but now hate eating non-spicy versions of foods I’ve grown accustomed to. Spicy peppers and hot chili powder have become a crutch for my otherwise mediocre cooking skills.

Yeah. The magnet quench flash boils a bunch of helium which is itself expensive, and presents a nice asphyxiation hazard as well. And then, assuming the quench damaged nothing, you have to set up the magnet again by getting the coils back down to superconducting temperatures… to get there, you end up boiling off a lot more helium. And then you have have to bring an engineer in to get the electrons spinning through the coil again and wait for the wobbles in the current to stabilize.

Or so I think. I work with NMR spectrometers and not MRIs, but it’s essentially the same technology.

In grocery stores in many parts of the US at least, it is extremely hard not to find bread in plastic bags. Even the one of 3 near me that has its own bakery puts the bread in a plastic bag, and then in another bag that is paper with a plastic “window”, and the paper part has a PE wax lining for god knows what reason.

Mitochondrion

I mean… just rotate it 90 degrees ((()))

Oh, I’m sure this’ll end well.

Good article, reactive web design notwithstanding (stop. breaking. my. scrolling). I’m not surprised that obtaining the chemicals was that easy, even accounting for the mislabeling and fake products. A lot of these chemicals are pretty simple and have pretty general use cases in the fine chemicals space. Hell, I had occasion to use (2-bromoethyl)benzene, aniline, and propionyl chlorde in school for making random precursors and ligands, albeit separately. I wonder if they are at all harder to procure nowadays because of the fentanyl epidemic.

Edit: checked some of my old work, didn’t actually use (2-bromoethyl)benzene but did make a related compound as an intermediate for ligand synthesis using a very satisfying Appel reaction.

That’s some expensive cereal…

So could we produce a surface tension-free water?

Homie dats a gas. Or supercritical fluid, which actually is indeed used for “washing” (SC CO2 is used to decaffeinate coffee). However, like others said, surface tension /= cleaning ability. Part of what soap does is increase the effective solubility of things that are not normally soluble.

So you’re saying that you don’t like trying to relight the thermal oxidizer for the formaldehyde stream that went out due to spillover from another process, with an emergency flare? Got it.

I mean, sure, things like that are super dangerous, but at least they’re obviously, flashily dangerous and for that reason have a lot more attention paid to them. The real nasties are arguably the ones that aren’t so flashy but are much more common amd don’t have immediate effects. Formaldehyde and benzene will give you cancer, and acrylate monomers will make it so you one day wake up allergic to the modern world.

This post made me go try something in clojure again and man I forgot just how fucking good the language is. Everything fits together so nicely.

TIL that influenza virions can be stick-shaped.

I went up to the Lake Champlain area where there was some high altitude cloud cover. Fortunately, it didn’t affect the viewing basically at all. A cool side effect of the clouds/related atmospheric conditions though was that the sun had a 22° halo. I wish that 1) I’d had a camera that could capture it and that 2) I’d had the presence of mind to pay attention to what happened to it in the moments before and after totality.

you mean let.

and then letting Hindley-Milner do the rest

Man I just built a new rig last November and went with nvidia specifically to run some niche scientific computing software that only targets CUDA. It took a bit of effort to get it to play nice, but it at least runs pretty well. Unfortunately, now I’m trying to update to KDE6 and play games and boy howdy are there graphics glitches. I really wish HPC academics would ditch CUDA for GPU acceleration, and maybe ifort + mkl while they’re at it.

Don’t a lot of these use the “strut” vowel (/ʌ/) and not schwa (/ə/) per se?

My transcription would be

/wʌts ʌp? wʌz dʌg gənə kʌm? dʌg lʌvz bɹʌntʃ. nʌʔʌ dʌgz stʌk kəz əv ə tʌnəl əbstɹʌkʃən. ə tɹʌk dʌmpt ə tʌn əv ʌnjənz. ʊχ./

So many solver solutions that day, either Z3 or Gauss-Jordan lol. I got a little obsessed about doing it without solvers or (god forbid) manually solving the system and eventually found a relatively simple way to find the intersection with just lines and planes:

1. Translate all hailstones and their velocities to a reference frame in which one stone is stationary at 0,0,0 (origin).
2. Take another arbitrary hailstone (A) and cross its (rereferenced) velocity and position vectors. This gives the normal vector of a plane containing the origin and the trajectory of A, both of which the thrown stone must intersect. So, the trajectory of the thrown stone lies in that plane somewhere.
3. Take two more arbitrary hailstones B and C and find the points and times that they intersect the plane. The thrown stone must strike B and C at those points, so those points are coordinates on the line representing the thrown stone. The velocity of the thrown stone is calculated by dividing the displacement between the two points by the difference of the time points of the intersections.
4. Use the velocity of the thrown stone and the time and position info the intersection of B or C to determine the position of the thrown stone at t = 0
5. Translate that position and velocity back to the original reference frame.

It’s a suboptimal solution in that it uses 4 hailstones instead of the theoretical minimum of 3, but was a lot easier to wrap my head around. Incidentally, it is not too hard to adapt the above algorithm to not need C (i.e., to use only 3 hailstones) by using line intersections. Such a solution is not much more complicated than what I gave and still has a simple geometric interpretation, but I’ll leave that as an exercise for the reader :)
