That’s some expensive cereal…
I was just looking at a 1950s paper at work about how some nutjob made a poly(alkene peroxide) (styrene, I think?), isolated the fucker, and lit it on fire just to see what would happen. those were the days. Nowadays some lawyer with a chemistry minor decides that our hand sanitizer bottles need big red PEROXIDE FORMER labels and 1-year expiration dates (true story, though no longer the case). Now, I’m not saying that we should be allowed to make polyperoxides for the express purpose of lighting them on fire… unless 😳👉👈…?
Do I not see the color because I’m protan or what? Does that even make sense for optical illusions?
7 is closer to 10 than 6 so we consider that 7 is really just a 10 with a size-3 hole in it and we fill that hole with 3 from the 6 giving a 10 with 3 left over which make 13.
Also not an ADHD thing.
It also can help with dental hygiene if your brushing habits are not symmetrical. I get tartar buildup on one side of my teeth if I don’t switch hands.
The sheets themselves are usually unproblematic, but the charts often don’t render properly when viewed in MSO. This is relevant because the other party usually does not have LO installed.
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.
I don’t use gVim, but for work stuff that I don’t have to share (mosly just notes), I use markdown in Obsidian w/ vi mode :) It’s not FOSS and Electron is bloat, but it is really slick, and my boss approved expensing the $50 seat license for business. I might check out logseq in the future, but Obsidian was a lot more mature back when I was looking around. My only beef is that Markdown doesn’t natively support sub/superscripts, which are kinda important for chemistry. Most editors implement extensions, but they’re not always portable.
Do you have an alternative to suggest?
For the general user? Not really, I’m just venting :) I have the unsubstantiated, possibly irrational belief that MSO UX ought to be far more polished after having existed for so long. Like you said, most of my frustrations have workarounds, even if they are buried or tedious (though the tedium is part of my contention).
For making slides or posters, someone in school recommended to lay out a poster or each slide completely in ChemDraw (basically a specialized, widely used vector-based WYSIWYG editor for organic chemistry) and paste the lot onto a PPT slide. That works reasonably well and makes everything have a consistent look, especially since most slides of mine contain chemdraws of molecules anyway. ChemDraw does have its own warts and somewhat limited functionality beyond drawing molecules and text. Also, since like 2019 the rendering and UI have gotten so much slower. For posters and basic diagraming, I currently use Inkscape, pasting things as needed. Inkscape also has its quirks, but its interface is so much more powerful and the UI so much more responsive than either ChemDraw or PPT that it is the clear winner for me. Though, it is also not winning any startup races.
For Excel, you’re unfortunately correct; there is no suitable WYSIWYG spreadsheet replacement. While I can do essentially all of the typical numerical hacking I do in Excel with (IMO) a better experience in LibreOffice Calc, it falls down when I need to show it to someone else. The charting in Calc is lackluster, and it doesn’t play nice with Office file formats. Also, my workplace (though not me personally) makes heavy use of Excel UI + VBA + fortran (!) DLLs for reactor modeling…
LO Writer is probably the closest to Word in usability, but compatibility with Word files is still subpar, mostly to do with styling and formatting. Both are bloated for probably 50% of my use (e.g., writing up informal procedures or meeting minutes). Wordpad (RIP) is nice in that regard.
it used to be a direct menu item but now it is quite buried…
My colleague swears that UI in MSO before Office 2007 was so much better, but I can’t comment much on that.
I mean, it’s okay… I feel like I run into inconveniences in MSO every day. Off the top of my head (solutions welcome):

Correct. The article in question reports that boiling specifically hard water results in the coprecipitation of some portion of the microplastics with calcium carbonate. The precipitate then settles out, and the depleted bulk solution can be decanted to separate it from the MPs.
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.
much obliged
A good exercise to dust off trig. Hopefully no typos involving u, v, 1, 2, α, and β.
By definition of |u| and Pythagoras, we can see that u1 and u2 can represent the lengths the legs of a right triangle with |u| being the length of the hypotenuse. Similarly for v. The triangles can be visualized in the usual way by plotting the vectors in the XY plane centered at the origin, with u1 and v1 constituting the X coordinates and u2 and v2 the Y coordinates of u and v, respectively.
Let α and β be the respective angles that u and v make with the X-axis. Then, θ = β - α, and
u1 = |u| cos α
u2 = |u| sin α
v1 = |v| cos β
v2 = |v| sin β
Now consider the expression:
|u| |v| cos θ
= |u| |v| cos (β - α)
= |u| |v| (cos β cos α + sin β sin α) (cosine angle difference formula)
= (|u| |v| cos β cos α) + (|u| |v| sin β sin α) (distribute)
= (|u| cos α)(|v| cos β) + (|u| sin α)(|v| sin β) (commutativity, associativity)
= (u1)(v1) + (u2)(v2) (substituting)
= u • v (definition)

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.
Nijmegen? Is it particularly exceptional, or just normal Dutch? /'nɛɪ.meː.ɣə(n)/, in a GenAm accent I would imagine something like NYE-may-ghen or NAY-may-ghen… but being American, it’s not something I’ve ever actually heard one of my compatriots say aloud.
