If there are numbers it's not real maths. The only numbers I use are 0, 1 and 2. Oh, and a few infinities on top. #NoTrueScotsman #CategoryTheory

That took me back :).

It means you're at least 10 years old.

OP is praying, so they'll be fine. /s

That's 80% of the reason I upvoted.

Some elephants happen to die of natural causes.

Human are primates, even. But what bothers me is having great apes in zoos. It's even worse with chimps. They're way too conscious to live in a glass cage. Or maybe they're fine with it, and I'm just projecting. They have less neocortex than we do, so abstract and hypothetical thinking is a priori harder for them, and they would have difficulties answering if we asked what they'd prefer. I'm so confused about all this.

I like that whales still have legs, but they're buried inside their bodies and not even connected to the rest of the skeleton. Just a handful of bones floating in the flesh somewhere.

Punker is technically correct, the best kind of correct. However there is a relation between heat and infrared. Actually there is a relation between temperature and wavelength, called "Planck's law", which is a mathematical formula that describes how much light an object emits at any wavelength for any temperature. The sun's surface is at about 5000--6000 degrees, so it's green (when seen without atmosphere, it's white with slightly more green than other wavelengths). Likewise, hot stuff starts glowing red, hotter stuff gets white, even hotter gets blue. And stuff at room temperature glows in the infrared. Extremely cold stuff glows at radio wavelengths (1% of the snow on untuned old television sets was due to the light emitted by the universe itself which is 3 degrees kelvin).
This is simplified (black body and stuff). But yeah, if you want to see stuff on earth without shining a light at it, you've got to be sensitive to infrared because that's what it emits naturally.

It's latex, not spandex. I go to Fetish parties with my gf (she models for several latex designers) and all the guys I know from these parties wear latex and are straight. Although we usually wear much cooler outfits than the one shown on this photo. I'm particularly proud of my Captain Picard uniform.

Also, teeth are stronger than bone. Look at the curved roots of a wisdom tooth, something has to deform when the tooth is pulled out; it's the bone. We wouldn't haven't evolved teeth if bone was strong enough. As for guest knowing stuff, maybe it's their job, or maybe they watch YouTube channels like "smarter every day", "today I found out", "Vsauce", or pretty much anything by the PBS network. Learning is easy and entertaining nowadays.
