something to do with liquid nitrogen? /s

ich, verwirrt: machen 6 kreuze aber nicht fis?

an den fingern abzählen…

oh. fis-dur und auch dis-moll.

bravo/a

Hot take: calories are the more intuitive energy unit. “How much energy it takes to heat 1 mL aka 1 g water 1°C” is more relatable than “how much energy it takes to move a 1 kg mass 1 m while accelerating that mass at 1 m/s/s”.

kcal = Cal is silly though

Side note: I know that the heating water thing is problematic because it depends on T, P, and purity (yay thermo), which is why these days cal is defines in terms of J. That does not change my opinion.

Hard water specically. I suppose that water softening is detrimental, then. I also wonder if this means microplastics can be used to remove lead by a similar mechanism. Maybe not considering that typical Pb levels are a lot lower than Ca in hard water.

I have this problem with organic chemistry more broadly. On the one hand, I understand that rattling off the IUPAC name of a compound is much less concise and harder to get right than just saying the brand name or chemical name (which, for pharma, is often just as bullshit of a name as the brand name). On the other, you come across names like the Eschenmoser-Claisen rearrangement vs the Johnson-Claisen rearrangement, or the Suzuki vs Stille vs Negishi vs Kumada vs Hiyama/Denmark vs Sonogashira* cross couplings. Each set consists of fundamentally the same reaction with slight variations in the specific reagents. Just saying e.g. “organozinc” instead of “Negishi” would be so much more descriptive. The authors’ names often aren’t even that helpful in an attributive sense. For instance, some of the cross couplings were actually first reported by someone else in that list (though IIRC everyone got at least one), and most of the chemists published work on at least one of the other reactions at some point.

* Okay fine Sonogashiras are a little different what with the copper co-catalyst, but still, same mech at Pd.

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.

Nah fam you can keep the see bugs, too.

Or spiced lentils… dal bhat <3

ahhhh nuts

One thing that helped me intuit the “sidereal” result (4) was to consider what happens as the radius of circle B approaches 0. At least in my mind, it seems pretty clear that A has to undergo at least one rotation.

That said, I am unsure that I would have caught this as a test-taker. Derek’s videos always have some “trick”, putting me on guard, but in a testing scenario I would have seen the answer for 3 with no answer for 4, marked it down, and moved on quickly.

My condolences, buddy.

You may be interested to know that these kinds of paper adhesives are usually intentionally designed so that the substrate (paper) tears before the adhesive does. This is meant to ensure robust packing and to give proof that the package has not been tampered with. Couple this with ever thinner and shittier substrates, and, well…

I wish whatever jackaſs that decided that the long ſ needed a ſtupid nub at exactly the ſame poſition as the croſsbar of the letter f in Roman typefaces a very unpleaſant afterlife. As if OCRing hiſtorical documents didn’t have enough problems already.

Maybe a dumb question, but if all of the vehicle’s bells and whistles are meticulously recording my every move… how do those data get back to the auto manufacturer anyhow? I read the article and the “how that works” link, and sure it mentioned phone connectivity, but if I don’t connect my phone, then my car presumably has no way to communicate what it collects… or are there a bunch of extra radios that phone home (satellite, cellular…)?

They are basically shortcuts. For example, I can type “!w ibuprofen” into DuckDuckGo (or the address bar because I have it set as my default search engine) and be brought immediately to the wikipedia page for Ibuprofen. There’s also !yt for youtube search, !so for stack overflow search, and many more.

0 mg Mg don’t forget the space between the unit and the number.

DuckDuckGo from the browser, because 90% of the time I can get where I want with the appropriate ! bang from the address bar.
