It can be a symbol for polarization of electromagnetic (EM) waves, with Electrical and Magnetic fields moving orthogonal to each other [1].

Unlike other waves like sound waves, EM has polarization component.

In wireless communication, for example, polarization can be used as another component for diversity to increase the performance of the communication channel.

> It's not a synonym for "goods", because only one type of thing was ever "wares"; software. It's just for dividing up the sections of your piracy BBS into, like "filez" (files, multi-kilobyte textfiles full of instructions on how to make bombs etc), "imagez", "warez", etc. Citation needed there. I have always assumed it came from fleamarkets where people selling pirated VHS films and knock-off Rolexes would be descr…

Okay, so my citation is, I was there, I was a (fringe) participant in pre-internet piracy culture, starting in 1990. Pirate BBSes would have various "goods" (in the sense you and GP mean) available for download, including images (hint: some of them may have involve ladies), text files, and software. Sometimes there would also be sections for various art media created by users, such as .mods or ASCII art or poetry or…

I'm not sure how you are missing it, but hardware and software both etymologically have ware (as in a manufactured article, product, or merchandise) built-in to them. Without ware, there would be no hardware or software, or warez. The root of these words, also silverware, cookware, courseware, Tupperware, Corningware, etc., indeed is "ware." And wares is merely the plural of ware.

> the thunderbolt ↯ is commonly used for "not" or more specifically for dis-proof in this area and I don't think it's that common. At least, I don't recall seeing it ever. Maybe it's used in non-English mathematics? Wikipedia mentions it's also used in electrolysis so maybe this new one is related to that somehow?

It's used in german mathematics education (secondary level), either to mark a contradiction in a proof or more generally to mark an erroneous statement.

But I have never seen it to mark negation of a condition, that's usually done with a slash (as in ≠ ≮ ≯ ≰ ≱ ≴ ≵ ⊄ ⊅ ⊈ ⊉ ⊊ ⊋ ∉ ∌ ∄ ∦, you get the idea).

So for "not a right angle" I'd have expected a "right angle" symbol with a slash through it.

>These unicode characters feel like they were given to us from an alien species or something. I worked at a large media company that had lots of differing icon sets in play across different media. These icons were in SVG and they had been optimized pretty intensely. In some cases due to a bug in one of the optimizing tools some types of bezier curves got weird, so instead of say the round headed person with their han…

I submit to you that it's clearly not a thunderbolt but an arrow indicating changing directions; that being overlaid on top of a pair of axes is obviously useful in the study of non-Euclidean geometry to indicate the use of wibbly-wobbly dimensions.

Particularly useful for timey-whimey relativistic analyses.

So Unicode has all these mysterious characters... but I would bet that it's still true that many people on the planet speaking common languages can't even type their name... This post is from 2015, and I'd love to know if unicode has added better support for non-English languages since then. https://modelviewculture.com/pieces/i-can-text-you-a-pile-of... Based on https://en.wikipedia.org/wiki/Bengali_(Unicode_block)…

I read that "I Can’t Write My Name" article when it came out and it's remarkably misguided. First, there are solid linguistic reasons why Unicode handles that character the way it does. Second, the article completely misunderstands how the Unicode Consortium works. Finally, the Unicode Consortium is remarkably open to character proposals from random people. The author could have written a proposal and fixed the probl…

Perpendicular + Unicode combining solidus = ⟂ + / = ⟂̸

I think perpendicular most commonly refers to lines/vectors/planes etc., while the right angle symbol refers to angles. Also, there are often multiple symbols expressing the same thing.
