Science because it's a rare biological condition, called sinistral (as opposed to dextral) chirality. You also learn a new "fun science fact": snails of opposite chirality cannot mate. (Only true for some species: for example, Amphidromus inversus has close to balanced dimorphic populations and can successfully mate both homo- and heterochirally, although hetero is more common).
Meme because it's a funny and relatable thing on the internet. Memes are no longer just image macros and memorable phrases.
Also, train dispatchers, power grid managers etc. Infrastructure control of any sort. On second thought, maybe they also have an extra keyboard/console (#16).
From a human's standpoint, we say they're "hot". The fact that humans can't handle 150 °C nor 2700 °C does not mean there's no difference between the temperature of a sausage fresh off the grill and magma. (Yes, by the time it gets to the surface, lava is too cold)
LED chips can't get above 150 °C or they fail. So high-power LED lights need appropriate cooling. And the heatsink is big and thermally conductive, making it feel hotter to the touch than it is (it delivers more heat to your finger over time). Meanwhile, the glass of some bulbs can exceed 300 °C but cools down to safe levels in a minute (or less if you touch it with something) because it's thin.
Also, 150 °C (420 K) objects do radiate heat as black-body radiation but not that much, also it's far-IR so only detectable with thermal cameras. Meanwhile, a light bulb's filament is 2700 K (3000
K in halogen ones) and the Sun's surface is 6000 K, and both produce copious amounts of near-IR light that largely contributes to the heat felt on one's skin when illuminated (although the visible light does too).
What is possible depends on your definition of "number", for example the Unicode digits mentioned only match \d (digit) in some Regex implementations. And some cultures don't have digits, for example Roman "Ⅴ" and old Italic "𐌡" (both mean 5 and look like an incoming flying goose) are numerals and never pass as \d. And Egyptian hieroglyphs 𓆏 (frog) or 𓆐 (tadpole but looks more like a parrot to me) can mean 100,000 but I haven't seen them called numerals or digits. Neither the eel-like 𔗄 Anatolian hieroglyph for 1000.
I focused on strings that a computer might spit out when asked to print a float but that might include "-Inf" (rooster in grass?), which mathematicians don't consider a number. However, they consider √7̅ (flying swan) a number, also "φ" (flamingo) aka golden ratio, equal to (√5̅+1)/2, and even complex numbers like -5+7i (flying bird with ornate tail). If you imagine a proper vertical fraction, ¼𝑒 (approx. 0.67957) could be a more detailed, wading flamingo. Coders will know what number -0xD7 (yet another sideways nesting/flying bird) is. And in some electrical engineering software, 1M7 (ostrich showing off its wings) means 1.7 million, 1p7 means 1.7 trillionths and 87j (rotate 90° right to see a chicken pecking at a seed) is the standard way to write "amplitude 87, phase 90°" - "j" is used for √-̅1̅ because "i" means current. However, most software, and likely this form, won't accept non-Latin numbers, math symbols and engineers' shortcuts (maybe the e/E for ⏨-exponent).
2 is a swan817 is an open-beaked screaming hatchling-2 is a seahorse.5 is a sitting bird6.6 is an owl-5e7 is a nesting chicken-5.43 is a peacock8008 is a tit
0 is an egg. Bird, fish, amphibian, reptile, who can tell? Truly a neutral answer - neither positive nor negative.
To help you visualize:
Also, number 4 in different scripts looks quite fishy ૪ or quite birdy ۴.

Thankfully, it's just the mobile providers and central directories of big companies (like railway operators, hospitals) here, very few others get the number of bot-serviceable phone calls to justify that. And they only recently started to ditch keypad-navigable systems and require you to speak, probably due to the state of Czech TTS (our language is phonetic so it's technically easier than English but with just 10M speakers, only recently did Big Tech really invest in Czech TTS, driving up the reliability/price ratio).
But American businesses at least take care that their website is up-to-date and not a 502: Bad Gateway page, right? So you barely need to make calls, right?
The new "AI" of one of Czech providers is super annoying.
"Thank you for calling. To make sure it's you, use your keypad to enter your numerical password."
[6 DTMF beeps]
"You entered 123456 [they say it way too quickly but OK, I have a feature phone so no butter finger errors]. Is that correct?"
(At this point, you cannot proceed until you say "Yes". Typing the number again (or anything else) will not help, you'd just hear "We couldn't hear that. Can you try again? To make sure it's you, use your keypad to enter your numerical password.")
"Yes"
"Thank you for verification. Please tell us what your problem is-"
"Human"
"We couldn't hear that. Can you try again?"
"Human"
"Are you sure you want to talk with our operator? The average wait time is 5 minutes."
"Yes"
(2 minutes of awful music and nagging to press 1 to reconnect to the bot)
"I have a question about your ToS since your website is down. Also, I don't ever want to speak to the bot again, can you bring the USSD text service or voice keypad menu back?"
Translation of the German part: "112 federal police? There's a Nazi here." − ["Are you sure?" (implied)] − "Yes, he has fascist symbols on all clothing." EU emergency number. I could change it to 911 but blatant fascism is legal in the US.
Anyway, what is causing the error? Is your ISP blocking feddit.org or do you get "403: Forbidden" like when I use AOSmium, the default browser and WebView on my AXP-ROM phone?
What does this mean? The character looks very androgynous and could be either male or female, trans or cis. Is this referring to how gender-neutral-looking people get assumed to be male?
