Proof that pi is irrational: Consider the following table. If pi=A/B, the values are an integer multiple of 1/B^n, but they tend to zero super-exponentially. QED (Actually this shows that pi^2 is irrational)

The word "eyeball" sounds like it's the name of a sport

There should be a suffix -inable that means the opposite of -able. This bowl is microwavinable.

McDonald's should do a big marketing campaign where they find out Ronald McDonald has a twin and at the end they rename the restaurant to McDonalds'

Noticed something interesting looking at a map of light pollution. What's this dot in the middle of the Teklimakan Desert, China? Is it a military outpost?

In graph theory, there is something called "Scheinerman's conjecture." It was proven in 2009, so it's not a conjecture anymore, but it's been known by that name for so long that nobody wants to call it anything else.

Given that Mandarin has the ü sound, why is Ürümchi transliterated as Wūlǔmùqí in Chinese rather than Yulümuqi? (Ürümchi in Uyghur is /ʏrʏmˈtʃi/, Wulumuqi is /ulumut͡ɕʰi/, and Yulümuqi is /ylymut͡ɕʰi/. The tones are irrelevant, but if you write it 于旅木齐 it could be Yúlǚmùqí.)

I need an English-speaking expert on Chinese film and television to do a video essay on the various Three Body Problem adaptations

Math is all about theorems. For instance, the Riemann existence theorem says there exist people named Riemann. The Riemann series theorem says there's more than one of them. The Riemann mapping theorem says that we don't know where they are. And the Riemann hypothesis says, maybe they're friendly.

My impression so far is: Chinese is a very structured language, with the added twist that you must learn how to draw your vocabulary words as well as how to speak them. Japanese is what happens when you make word games the basis of your language. The only rules are fun and vibes

Me at the end of a talk: "Questions? Comments? Concerns? Criticisms? Corrections? Condemnations? Complaints?"

I sued the UK 2½ years ago for refusing to issue me a Gender Recognition Certificate to match my birth certificate, despite what the law clearly states. My appeal hearing has now been confirmed for tomorrow at The Royal Court of Justice in London, court 63, "not before 10:30 am".

We're cleaning out the Platonic realm of forms, what stuff do we wanna keep and what stuff do we wanna throw away Be careful 'cause we accidentally got rid of the nice packing of 17 squares in a square, and now we just have crap ones
