do you think anyone's ever typoed "AI foom" as "AI foot" and accidentally glimpsed a bunch of AI generated foot kink images

I was going to say googling "AI foot" probably doesn't give you a bunch of AI generated foot pics but it totally does. still think this is pretty unlikely cause of how far T and M are from each other on the keyboard

on what keyboard? they're very close

a scientist's h-index is the maximum h such that they have h papers with h citations each

by analogy, i introduce the t-index: a blogger's maximum t such that one has t posts with t notes each

calculus has ruined my brain i see dx for diagnosis and i think of arbitrarily small rectangles

phonetics has ruined my brain i see ʃ for integration and i think of voiceless postalveolar fricatives

Why do we use τ to represent 2*π when we could use ℼ

dkl9

being a double-stroke letter people might interpret it like ℂ (complex) or ℕ (naturals) i.e. an infinite set/number system

perhaps SO(2)

Geology: I think geology should be one of the big fields of science. It doesn’t really fit neatly as a branch of physics, chemistry, or biology since it draws on all three.

Physics: No. For one, everything is physics so that argument doesn't mean anything.

Biology: UnLeSs iT's StAmP CoLlEcTiNg, right?

Physics: *sighs*

Biology: Also we’re called ‘the big three’, if we added another then it’d be, like, more than three. Some mysterious higher number.

Chemistry: Besides, we’re the big fields because we’re the most important and popular.

Geology: Geology is important! We’re the ones who find all the oil to mine!

Biology: Yeah, could you stop doing that, actually? It’s kinda, y’know, causing the slow apocalypse as we speak. But at least it’s better than the fast nuclear apocalypse, physics.

Physics: Ummm… You know what? I’ve had enough of you stamp collectors with your… uh… collections of things! I'm not letting you join our club unless you can do math.

Biology: *Gasps* not math…

Geology: *hides rock collection behind back* Hey, I do… math. Sometimes.

Physics: Yeah? Like what?

Geology: Oh, y’know, just some geometry and a little geophysical fluid dynamics of the entire mantle, ocean, and atmosphere.

Physics: Oh, shit, I can't even do that. You’re in.

Chemistry: Alright, but don’t let the social sciences know we’re letting new people in or-

Anthropology: HEY GUYS

dkl9

Physics: Anthropology is just stamp collecting ... which is to say that people are just stamps, yes.

Pure logical argument weakens claims

In formal logic, the law of addition says that, from true proposition P, you can correctly conclude P∨Q, for any propositions P and Q.

...

P∨Q is weaker (less strict) than just P. This is true, but it's not unique to the law of addition. Every fundamental logical law produces conclusions at most as strong as its inputs, and often weaker.

...

Logical work just helps to interpret the set of worlds your observations accept as options. If pure logic could rule out possible worlds, you might rule out the one true world and not know it, thereby missing the point of valid argument.

Logic is still useful sith a weak claim focused on what we care about (like the mortality of Socrates) is often more useful than a more precise claim with confusingly irrelevant details (like the humanity of Socrates and the mortality of humans).

Applying modus ponens, conjunctive simplification, or syllogism doesn't get rid of the strong input claims P, P∧Q, or P→Q, respectively — they don't diminish your total knowledge — but addition just as well keeps around the original P, and to ignore that is to judge logical laws by different standards.

I would like to know why the same answer is given twice.
