A cheap blood pressure pill can take the sting out of painful memories Propranolol blocks emotional memory reconsolidation. Recall a trauma on it and the memory comes back duller.

All those moments will be lost in time, like tears in rain...

"In a 2015 experiment, Dutch researcher Merel Kindt gave propranolol to arachnophobes right after making them sit with a tarantula for two minutes. Some participants ended up holding the spider."

Non mais ça ne se fait pas de fouiller dans les archives des blogs un peu anciens à la recherche des trucs embarrassants, comme ça. 😠 C'est un peu comme si on allait dénicher des vieux tweets des politiques pour montrer qu'ils ont dit des choses embêtantes.

OK, yes, but I find it a bit different to transliterate words that don't have an obvious translation or that are associated to a particular language than to write “Indian something” in English in an Indian script.

And if the point was to not just address the Hindi-speakers in India, then this fails too, because Devanāgarī isn't widely used outside of Hindi.

Or does the Indian Oil logo read “இந்தியன் ஆயில்” (this is still English!) in Tamil Nadu? 🤔

I don't know Hindi, but I'm pretty sure the way you'd say “Indian oil” in Hindi (maybe “भारतीय तेल” or something of the sort) isn't to transliterate the English “English oil” into the script. I know for a fact that Hindi has a native word for “India” (one of the few words I know). 😁

Photo of a sign with the IndianOil logo on it, which is a red-orange circle (with a blue outline) with text that says “इंडियन ऑयल” in white on blue characters in the Devanāgarī alphabet.

I was glancing through a BBC news article photo when it struck me that the logo of the India company Indian Oil says “इंडियन ऑयल”, which is the transliteration in Devanāgarī script of “Indian Oil”. Transliteration, not translation! This is English, but written in Devanāgarī. 😮

Why are we bothering with the Strait of Hormuz when we could simply do this? Explain it to me like l'm 5.

The meticulously detailed and beautifully illustrated Wikipedia page for the profanity “fuck” and its wide gamut of meanings is a wonderful example of how Wikipedia can turn a seemingly frivolous subject into something simultaneously wonderful and absofuckinglutely hilarious.

Serious question: how do other birds of the same species (say, a corvid species) react to an albino individual? Do they identify it as one of their own? Ignore it? Attack it? How do the parents react when their offspring is white?

Of course darling you can be Braveheart and Maverick from Top Gun and Master Chief from Halo and Superman and whatever you want. You're twelve, so of course you want to impress us all.

Another comparison I like is with a fruit tree: if someone wants to grow fruit and tries to cut all the roots from a fruit tree because no fruits grow on those parts, they are in for a surprise.

This is what we need to tell politicians who ask “why do we need pure math for?”. •4/4

Math research (or all of science, actually) is like a brain: even if you are interested only in one task (say, creating practical applications), you can't just remove or starve the brain parts that don't seem to directly connect to that task and hope everything will still work just as well! •3/4

… but slightly misleading.

I would say the main reason we study very abstract math isn't for their applications outside of math, but because they connect to other areas of math which themselves connect to others, etc., ultimately to applications.

And you can't just chop one part of this off! •2/4

This is interesting, but let me offer a counterpoint: I think it's generally not a great strategy to try to argue that even very abstract math concepts can have sometimes unexpected applications. It is ✵true✵ — like abstract number theory turned out to be fundamental to cryptography ― … •1/4
