  • 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.






  • That’s not the gotcha OOP seems to think it is. If the world was magicked into existence by a supreme being 4000 years ago, there’s no reason it couldn’t have been magicked into existence with heavy elements having decayed by an arbitrary amount or with Pb by itself. 'Tis the problem with invoking appeals to magic. And anyway a quick look on wiki says that primordial Pb was mostly created by neutron capture of lighter elements, not radioactove decay of heavier ones, so the mere existence of Pb proves nothing wrt the timeline of U decay anyway… but at that point if you’re bringing nucleosynthesis into it, you may as well point to anything higher than lithium or even atoms as a concept as “proof” rather than picking anything as exotic as uranium decay.







  • 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.

    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.
