  • I realize (and you mentioned) that sugar is not a well defined term, but calling degradation products of ethanol in gas “sugars” is still a bit of a stretch. Ethanol by itself usually forms some combination of acetaldehyde, acetic acid, 2-carbon peroxides, and CO2 (i.e. not sugars) upon autoxidation, though those species can react with other components of gasoline to form the precipitated “gum”. The structure of gum in the literature is pretty hand-wavy (high MW materials kinda just be like that sometimes) but tends to be much more more oxygen-deficient than conventional “sugars” (polysaccharides) even for ethanol blends and contains a wider variety of substructures. Though, I have seen some papers talking about certain microbes that can ferment the ethanol in gasoline, possibly via sugars, but I don’t think that’s the common degradarion pathway for a mower.



  • I got one because I was intrigued by its lead rotation, but I found that it really didn’t rotate the lead enough while I wrote. I kept having to rotate the barrel manually to keep a thin line like I do for every other mechanical pencil, and then would get annoyed every time the clip came around to brush my hand. I’ve been wondering if I’m doing something wrong, or if Japanese just uses more shorter strokes. Do you also like it when writing English?


  • So I found this website that lists specific heat capacities for various foods, and while it doesn’t list “snacks”, dry foods values seem to range from 0.3 to 1 cal•g-1•K-1 = 0.0003 to 0.001 Cal•g-1•K-1. Assuming no phase change (i.e., melting) and otherwise temperature-invariant heat capacity, the energy required for heating a 100 g snack from freezer temps (-18 °C) to body temp (37 °C) is 1.65 to 5.5 Cal. More realistically, we can compare to eating an ambient-temp (20 °C) snack; that difference is only 1.1 to 3.8 Cal… in either case, the difference is negligible, generally < 1% of the calorie count of the snack itself.


  • 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.



  • 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.
