    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

  • Checking for available updates + kernel mismatch on every new terminal - How can I speed it up?

    Jump

  • Yeah, run checkupdates in a timer, and then in your script invoke checkupdates -n

    https://man.archlinux.org/man/checkupdates.8

     
        
-n, --nosync
Do not sync the temporary database, works   
best when the temporary database is   
updated regularly through some other   
means such as a cronjob or systemd timer.

  • 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:

    cos(x) = 1 - x2/2! + x4/4! - ...
    sin(x) = x - x3/3! + x5/5! - ....

    We now start with the definition of ex Taylor expansion, and proceed to do some substitutions:

    ex = 1 + x + x2/2! + x3/3! + .... + xn/n!

    We can then substitute in: x=iθ (remembering that i2 = -1) to get

    eiθ = 1 + iθ - θ2/2! - iθ3/3! + θ4/4! + iθ5/5! + ... etc...

    If we group by real and complex, we can arrange the above as:

    eiθ = (1 - θ2/2! + θ4/4! + ... ) + i(θ - θ3/3! + θ5/5! + ... )

    You should now realise that the left part resembles the expansion of cos(θ), and the right part resembles sin(θ). That is:

    eiθ = cos(θ) + i sin(θ)

    Finally, we substitute in θ = π

    eiπ = cos(π) + i sin(π)

    And we know that cos(π) = -1, and that sin(π) = 0, meaning that we end up with

    eiπ = -1 + i 0

    or

    eiπ + 1 = 0

    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

    eiπ = -1

    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.
