I feel like this would be a good theme song:

"contrapositives are for cowards"

desmos-calculator

y'know, one of the goofiest things I've learnt from the desmos community is that { } with nothing inside equals 1

but that's not just it, you can also add { }s

and it functions just the same as adding 2 1s

but therein lies the funniest part, that you can perform almost any function on it, from minus

to exponents

to even factorials!

and lists too!!!

you can even compare solutions of { }s in { }s

there's almost no restrictions, if you can do it with numbers, you can do it with { }

and this leads me to what I've seen a lot of people calling "desmosfuck" after the infamous programming language brainfuck, and it restricts you by not allowing any letters and no numbers, that includes sin, log, x, y and all the others. The only thing you can make out of { }s are points and numbers though, but thankfully that's usually enough to make a bunch of stuff.

like, if you need π, just use (-0.5)!^2

you need e? you already have π and i, just use e^(iπ)=-1 and rearrange it to e=-1^(1/(iπ)) and get -1^((π^-1)(i^-1))

want phi? sure, just use it's surd representation of (1+sqrt(5))/2

okay, but what if you really wanna do functions? well, if you're desperate, you can sorta do that, you just gotta use a concentration of points.

cos(x) and sin(x)? use the identities

cos seems easier

and x just has to be a dense list of numbers

now that we have x, let us... REWRITE!

that's dense... buuuut, it does the job as soon as we add the x part to the x coordinate!

absolute insanity

you can also get sin by subtracting x by half of pi

awesome

here's tan, btw

go play around with it yourself! it's very silly

Tiny hexagon-spiral booklet with friend-shaped friend shapes of joy (platonic and archimedean solids drawn in isometric projection)

Laying at a stone to make the hexagon-spiral booklet appear more plastic:

This booklet can be folded into a tiny hexagon with moderate thickness:

So the new firmware update 20210505 for the HP Prime graphing calculator has a Python App. I guess I'll have to learn Python now.

(1+9^(-4^(7*6)) )^(3^(2^85))

Contains all digits from 1-9, which is trivial, but kinda cool.

It’s also a good approximation to e, which is pretty exciting.

If I told you it was correct to four billion, sixty seven million and thirty five decimal digits, would you believe me?

Well you shouldn’t, because it’s actually correct to 18,457,734,525,360,901,453,873,570 decimal digits, which is way more than it ever should be.

This is a summary of college only using two pictures; expensive as hell.

That’s my Sociology “book”. In fact what it is is a piece of paper with codes written on it to allow me to access an electronic version of a book. I was told by my professor that I could not buy any other paperback version, or use another code, so I was left with no option other than buying a piece of paper for over $200. Best part about all this is my professor wrote the books; there’s something hilariously sadistic about that. So I pretty much doled out $200 for a current edition of an online textbook that is no different than an older, paperback edition of the same book for $5; yeah, I checked. My mistake for listening to my professor.

This is why we download.
