Complex numbers are as real as the Real numbers.

[-] kogasa@programming.dev 55 points 11 months ago

For that matter, the real numbers are fake as fuck. "Ah yes, let's just throw in uncountably many non-computable numbers." They have played us for absolute fools.

Big math is laughing at us right now

The set of all rational numbers has zero size in the real numbers. And yet, they're fucking dense, meaning you can find a rational arbitrarily close to any real number. I mean, what the fuck?

That's it, I'm Amish now. I use inches and fractions of inches, and that's as far as my numbers need to take me

No that just makes you an American Mechanical Engineer.

Their subset, irrational numbers, is somehow worse

"there are as many even/odd/prime/composite numbers as there are numbers"

g(63)? TREE(3)? BB(10^100)? Rayo's Number? Fuck outta here with that fake bullshit

[-] starman2112@sh.itjust.works 2 points 11 months ago

Yeah TREE(3) is so big, how can you possibly know that there are that many evens??

The fact that you can’t solve any real life electro-magnetism problem without them kinda put an end to that complex shaming nonsense.

Yet there are still people to miss the absolute poetry of their story.

In 1545, an Italian genius called Gerolamo Cardano was pissed he couldn’t solve square root of negative number.

« Fine! I’ll make it myself » he said, before sending everyone to hell.

He then invented an imaginary number i whose square would be -1.

It wasn’t until centuries later that another famous genius named Leonhard Euler found a practical use of those numbers.

Without those numbers we would still be living like 1800´s peons.

In 1545, an Italian genius called Gerolamo Cardano was pissed he couldn’t solve square root of negative number.

Iirc, it was while trying to solve cubic polynomials, that he found out that accepting the existence of sqrt(-1) let him solve them.

It's sorta strange that complex numbers seem to be basically used as an ersatz coordinate system.

[-] lorty@lemmygrad.ml 2 points 11 months ago

Not only that, but their existence is implied wven when working just with real numbers!

[-] ziggurism@lemmy.world 0 points 11 months ago

complex numbers are just numbers in a plane instead of a line. saying you don't believe in i is like saying you don't believe in "up"

[-] nodsocket@lemmy.world 0 points 11 months ago

I can't tell if this is supposed to be a joke

[-] EmoBean@lemmy.world 17 points 11 months ago

I'm irrational because I'm a πces.

[-] fossilesque@mander.xyz 5 points 11 months ago

Can I pi you a drink?

[-] fastandcurious@lemmy.world 4 points 11 months ago

I remember a very beautiful line my teacher told me

Its translated so it might not be as good

‘It’s not necessary for everything to have a meaning, but everything does bring meaning if you know how to use it’

[-] fosho@lemmy.ca 2 points 11 months ago* (last edited 11 months ago)

the punchline comes before the joke.

what's the worst part about time travel jokes?

[-] CyberTailor@beehaw.org 1 points 11 months ago

Soyjak saying "√(-1) = i" would make more sense
