Isn't the squaring actually multiplication by the complex conjugate when working in the complex plane? i.e., √((1 - 0 i) (1 + 0 i) + (0 - i) (0 + i)) = √(1 + - i^2^) = √(1 + 1) = √2. I could be totally off base here and could be confusing with something else...

New strategy to prevent global warming: just freeze all of the CO2 out of the air!

inhales

Complex 1a was prepared according to well-known synthetic procedures. The reduction potential of the complex was increased due to the nephelauxetic expansion of the occupied FMOs induced by photolytic epimerization of the auxiliary tetrahydrophosphazolidine sulfide ligand to enable a strongly σ-donating dihaptic coordination mode.

translation: we made molecule 1a, we shouldn't need to tell you how, it's obvious, lmao, git gud. the molecule became less likely to gain extra electrons because shining light on it made one of its weird-ass totally-not-bullshit parts wiggle around a bit so that it could bind more strongly to the metal atom through two of its own adjacent atoms, making the metal atom's relevant electrons floofier.

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.

Counterpoint: advisor said no.

"Just use Word, everyone else does. I have never heard of this latex thing, so must be just some trendy useless overengineered software that does Word's job but worse. Word can track changes just fine, and you can leave comments." proceeds to strikethrough, highlight, and inline comment everything instead of using either of those features "I want to read what you wrote, not fight technology" proceeds to email you three separate times after forgetting to attach v28 about how a graphic looks wrong because Word ate 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./

"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 through 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 referred 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.

Edited for TLDR: no one knows, both forms have historical support; it doesn't matter, go crazy

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...

Sawdust is not (just) cellulose and cannot be listed as such on nutrition labels. Sawdust, i.e., wood shavings, contains many other compounds, especially lignin. Wood is refined by e.g. the Kraft process to separate the lignin from the cellulose, giving a suspension of cellulose fibers in water called "wood pulp." I didn't look, but I would imagine that calling wood pulp "cellulose" on a nutrition label is fine, 'cause that's what it is.

Now, none of this invalidates the crux of your argument that cellulose can be used as a cheap filler, such as in cheap "Parmesan cheese," and no disagreement here that that shit is scummy af. However, there are some legitimate uses for smaller amounts in foods, such as anti-caking, thickening, and literal dietary fiber.
