Im an anything bird - by that I mean that caffeine dictates my schedule.
If I work UK timezones, then my last coffee is at 3pm and I’m in bed by 11:59pm and up at 8ish.
If I work US timezones, then my last coffee is at 8pm and I’m in bed by 4am and up at 12:01pm
I have a high school friend who owns a paper mill. He was a rich kid who never did the work, and always took credit for others work.
He has an h-index of 90 and 200,000 citations. He is not a professor.
For (1), we started with the Maclaurin series 1/x to get us familiar with the idea of differential expansions, and then we moved to Taylor to derive expansions of some common functions like cos and sin:
We now start with the definition of ex Taylor expansion, and proceed to do some substitutions:
We can then substitute in: x=iθ (remembering that i2 = -1) to get
If we group by real and complex, we can arrange the above as:
You should now realise that the left part resembles the expansion of cos(θ), and the right part resembles sin(θ). That is:
Finally, we substitute in θ = π
And we know that cos(π) = -1, and that sin(π) = 0, meaning that we end up with

The teacher got excited because it is literally one of the most beautiful mathematical statements you can get, that connects five universal identities under a single statement: 0, 1, e, i, and π – and does so using 3 different operators (times, power, plus).
For (2), I’m still waiting as I think it’s currently holding the world together by sheer mass alone
My high school teacher introduced this to us as a slow reveal over the course of weeks of what would be the proof of
The happiest moment was when he brought in these two disparate field of mathematics, complex numbers and series expansions, and hit us with this magnificent revelation. Once he drew it up, he stood there shaking with excitement, beaming at us at how amazing this all was.
The class wasn’t having it. We were teenagers. We understood it from a purely proof level, but did not get the implications. It was years years later that it all hit me how amazingly neat it was of the universe to unite these fields together like that and to unearth literally new tools we could use to explore further fields of maths.
Thankfully since then I’ve started dating Taylor Swift and reading the words of Samule Taylor Coleridge, whilst getting clothes fitted to size at my local clothes-maker guy to fit my enourmous expanding schwang.
oh I’d teach 'em modern english, and then dump a truck load of People’s Magazine’s outside their hut
Going for a hunt today? Can’t. Need to know what Janniston said to Branjelo on page 4
US and Russia would tear themselves apart internally. That leaves China with the largest functioning army, vs the EU if they can mobilize fast enough
Didn’t all dinosaurs die for our sins?
Empathy tends to be a byproduct of considering another person’s point of view and not immediately assuming the worst. There is definitely intelligence there, if you are considering all angles
Huh. Never had an issue with that before, but TIL

Oh believe me it’s coming. UK pays weather roulette a lot, and an umbrella is the perfect weapon
Briefcases. Once briefcases no longer became practical, laptop satchels had a moment, but then the straight-edged kids realised that backpack was just superior in every way, so they begun to one-strap it out of convenience, and once you carry a backpack with one strap, that’s a slippery slope to being chill
