they call my dick the traveling saleswoman the way its NP-hard
and i can use it to generate the shortest possible route between each point in a set of points (visiting each point only once)
Motivating example: Ok so latex complaints. When you type not equals and the empty set, the lines aren't parallel.
Lemma: This is fixable.
Proof: A silly little application of $\neq$ \rotatebox[origin=c]{22}{$\varnothing$}
Remark: There are other options. If you dare.
After consulting with my esteemed colleagues, we have the following results.
Corollary:
wasn't parallel to the sides of the post, fixed that for you though!
the moon is literally my favourite circle
OOH THATS A REALLY GOOD PICK!
YESSSSSS
amazing. brilliant.
that is so cute
unending peace and joy....
this wasn't a quote from a real PDF btw I just thought it would be funny to tex this up so it looked like one instead of posting it directly
the next evolution of Tumblr shitposting is looking promising
believe it or not there is an xkcd for this

‘Hands weaving magnetic-core memory, IBM, Poughkeepsie, New York,’ 1956. Photograph by Ansel Adams.
My mother used to make computer cores as a "work from home" side business. As a child I got spending money via un-winding the ones that failed testing so that the magnetic center could be re-used. I got between $0.05 and $0.25 per core depending. Mom got more for the finished ones, of course, though I don't know how much. Her sister was an expert, and did the more complicated kind, some of which ended up in satellites and/or were used by NASA!
They were all done by hand using a kind of treadle-operated frame with a little (crochet!) hook to pull the wires around the cores. The people making them were mostly housewives who did this as a side-job in the 80s and 90s. I don't know if it's still done that way anywhere in the USA today, but the history of computing and space exploration is littered with "women's work" like this.
really like the number 49 recently. it's one less than 50 which is obviously a super clean and even number it makes 49 look meager by comparison . and it's 7 squared which I don't normally like 7 it's overused but it still has to be acknowledged as somewhat of an odd indivisible number it has some under dog quality to it. and then it tries its hardest and becomes square but it comes just shy of 50 . being beautiful and round and even but. 50 isn't a square. it's the sum of 2 squares and also half of a square but . even though it may seem like a failure, 49 has achieved something that 50 only dreams of
You wanna fuck 49 so bad it makes you look stupid
i just feel like some numbers are really special and that it’s kind of cool to catch them at it. like youre headed to your friends address, and the first part is, say, 961, and you’re almost there before you realize that 961’s a perfect square with a prime number root. and its like taking clark kent’s glasses off. you’re like, you sexy bastard, you thought you were gonna get away with just being a normal number? no. you’re incredible and i caught you at it. god youre soooo hot. who said that.
yeah. many such numbers.
im a little wine drunk but please post your favorite numbers and i will rate your taste later. or sooner as my hudgemnt wanes.
i went to my actual computer so that i could type both more clearly and in larger quantities. this is SERIOUS BUSINESS TO ME.
you guys have no idea how beautiful numbers can get. 256 isnt a secret celebrity! everyone knwos 256! borderline overrated!
65,536 is the sexiest power of two number because its 2^2^2^2. and in theory you could go more twos above that because then the number is just unmanagable huge. too absurd.
i respect your gendering of 256 though. she gets to be a she. forever. now.
i like palindromic numbers. theyre just really hard to get reliably without doing powers of 11. but also, you know, it's a little elementary. hes already famous! everyone knows why 121 is hot. which doesnt make him less hot but its just a lesser developed aestheticism.
ohhhhhhh that flippy thing in the powers is makiny my brain go brrrr. thats hard to do. is that a powers of 2 thing only? 2^3 is not 3^2, so its like... even powers of two? no. no. no. oh. theres a unique little puzzle in that. i had no idea. wonderful taste. thank you. complimentary calculator.
i cant critique these. im glad you are participating and one day i hope you find a number that makes you pull up desmos and make borderline pornographic graphs. but for now 9 and 2 are good. yeah.
44 is the oatmeal raisin cookie of numbers. why is he your favorite. hes not even good. nobody likes him but you. are you old? are you evil? how did you get to this point? bleh.
23 and 29 do that but theyre a lot less sexy. you got flair here. moxiy. PIZZAZ. youre gonna go far. keep this shit up.
okay this is nice but its. its a little. eh. everyone would get why this number is hot. like. you're missing out. there are numbers out there liek that spinning danceri llusion, where you cant stop seeing them after you see them. your eyes change. that number is permanently hot now. and its even hotter because you figured it out. you went wait a minute mr. number. i know what youre up to. and i like it. keep doing it. 369 is like, yeah yeah, everyone knows what you're up to buddy. cool trick. 369 is the guy with an acoustic guitar at the party playing ed sheeran songs.
i feel like 223 is more interesting than 23 but as you got that and more i cannot fault your taste. you're a little math freak and i appreciate that.
eh.
im taking notes here. im not a homewrecker, im not gonna steal your number husband (nusband?) but like. i get it. exsquisitve taste here. i kind of thought that 144 was amateur hour but the 441-144 thing is like. ooooooo. impressively flexible.
you gotta give me a pitch on the 6561. and 4096 is still amateur hour binary. 2^14 malarky.
honestly surprised it took this long. honestly. i respect it.
okay that is dope. like its not crazy math just sitting there but it takes a special kind of brain to notice that. life is funny of interesting coincidences if you just let your brain run wild looking for them.
you get it you get it. theyre like. atomic. in the greek sense. they are the building block of every other number. when you break something into primes its like hnnng and when those primes are like. 3 or 4 digits long its like HNNNNNNNNNG.
idk then perish 44 is a lame number. lame! i mean. it's an even number for god's sake. yuck.
okay. i. hm. i do like that explanation. 22, twice. that's like three twos in a way. im. im gonna give it a shot. ill try anything once.
you are the only person to include a non-transcendetal number with decimals in it. you're a real freak. i dont get it but im glad youre here. you are like. the furry of the numberphile world. please go draw some 34.6 fanart. sell us on this. dig deep into your mind palace and bring to us its awful treasure.
i hear you. and i get it. i have some love for the 80085 poster. but its 69. theyre 69ing. i dont make the rules.
3*3*3 is like. mm. that makes my brain feel like i just scratched it. i like 729 because it's 27 squared and thats approaching the limits of my mental math. id looooove to be able to do 27 cubed all instantaneous like but 729 times 27 just makes me get all jumped. im like. uh. uh. uh. shit. 729 times 30 is 21000 plus 870, so thats not too bad, thats 21,870, and then i can skip the 729 times 3 part just by going, take 10% of the 21,870, so thats 2,187 #lazymath. but then subtracting that from 21870? too many digits to carry. i cant fucking carry digits in my head. i have to break it into more steps but that point im already out of steps and i need to sit down. smoke pours out my ears. i despair.
(anyway u have succesfully defended your thesis i hereby pronounce you a numblr use. god forth and count with god. )
i think i responded to everyone? thank you all for participating in babylons numberphile safari. have a great day, and please drink responsibly.
I'm fond of 8999! It feels like a drive-by number but it's a surprising prime, which is always fun. More than that, it's a twin prime! I love twin primes in general but 8999 and 9001 are so cute together. Secret besties.
You! I forgot about you. Your number tastes are immaculate and you deserve to be heard.
did you know they say calculus is the language of God. did you know they tried to hold math up to infinity like a candle to the void. did you know statisticians plunged into the vastness of random chance and picked out patterns and equations and eight hundred ways to tell you how big your inevitable errors are and how far off those guesses at errors might be. math haters I can't sit with you anymore. human innovation is cradled in these ancient, methodical, desperate attempts at understanding what we are not designed to understand

you either die a mathematician or live long enough to see yourself become a computer scientist
bad news, euclid fans! i just disproved his assertation that parallel lines don't intersect for their entire infinite length. i walked along them for approximately 8.6 x 10⁸ km and you know what i found? that's right, a tangle.
they don't touch for the rest of their infinite length though, i did check. in both directions.
i'm sorry that's my fault i was walking along that stretch earlier and accidentally tripped and tangled them up and i couldn't get them untangled and i thought no one would notice i'm so sorry
Proof by you'd really think so wouldn't you?

Kindergarten-level math research papers:
Field: Combinatorial Number Theory
Journal: Communications in Addition and Subtraction
Title: A Lower Bound on the Largest Natural number
Abbreviated Abstract: We prove a lower bound on the largest number. The proof proceeds in two steps: we begin with 1, and proceed by induction as until we lose count. We then add that number to itself. The main advance in the first step is to get a big number, and the second step notably avoids using multiplication (they don't teach that until 3rd grade).
Field: Topological Geometry
Journal: Advances in Nonlines
Title: The Four-Color Scribbles
Abbreviated Abstract: In this work we show a zoo of examples of nonlines (curves) with the unique property that they are either red, blue, orange, or purple, or some combination therein. The key idea is to use less colors rather than more, creating a clear and easy to follow proof. This provides a clear basis for simplifications to further work, such as scribbling with 5 colors.
Field: Playground Analysis
Journal: Slide Dynamics
Title: Sufficient Conditions to Yell Weeeeeee on Spiral Slides
Abbreviated Abstract: We identify sufficient conditions for a slide to cause joy. We identify a notion of a "fun slide," and prove that fun slides are a sufficient condition to make someone go Weeeee on a slide. We then verify a spiral slide is a fun slide, and provide numerous examples and non-examples (notably, a ramp is really not fun to slide down).
A circle inscribed in a square covers 79% of the square.
A ball inscribed in a cube fills 52% of the cube.
A 4-ball inscribed in a hypercube fills 31% of the hypercube.
A 5-ball inscribed in a 5-cube fills 16% of the 5-cube.
⋮
A 9-ball inscribed in a 9-cube fills it up less than 1% of the way, yet there’s no room to fit a second ball of the same size without intersecting the first.
⋮
In dimensions 23 and up, you can fit a little cube in the corner of the diagram, such that the cube has a larger volume than the ball!
That's especially disconcerting because the 23-cube has 8,388,608 corners. Even if you inscribe the little red cubes in all eight million corners, your big cube will still be 99.5% empty space.
if you take a square with side length 4 and put a unit circle in each corner and construct a circle in the center of the square such that it is tangent to each unit circle, its radius is √2 - 1 ≈ 0.41
if you take a cube with side length 4 and put a unit sphere in each corner and construct a sphere in the center of the cube such that it is tangent to each unit sphere, its radius is √3 - 1 ≈ 0.73
if you take a tesseract with side length 4 and put a unit hypersphere in each corner and construct a hypersphere in the center of the tesseract such that it is tangent to each unit hypersphere, its radius is √4 - 1 = 1, another unit hypersphere
if you take a 5-cube with side length 4 and put a unit 5-sphere in each corner and construct a 5-sphere in the center of the 5-cube such that it is tangent to each unit 5-sphere, its radius is √5 - 1 ≈ 1.24, and indeed from here on out our central n-sphere will be larger than the unit n-spheres it is constrained by
...
if you take a 9-cube with side length 4 and put a unit 9-sphere in each corner and construct a 9-sphere in the center of the 9-cube such that it is tangent to each unit 9-sphere, its radius is √9 - 1 = 2, which means it is now also tangent with the 9-cube that is constraining the unit 9-spheres that are constraining it
if you take a 10-cube with side length 4 and put a unit 10-sphere in each corner and construct a 10-sphere in the center of the 10-cube such that it is tangent to each unit 10-sphere, its radius is √10 - 1 ≈ 2.16, which means it now sticks out of the 10-cube
in general constructing this arrangement in n-dimensions results in the central n-sphere having radius √n - 1, which grows without bound as n increases, so not only does the central n-sphere extend beyond the constraining n-cube for n≥10, but in the limit its radius diverges to infinity, despite being constrained by 2^n unit n-spheres which are entirely contained inside the n-cube with side length 4
