Unique Fractions between 0 and 1, visualized in polar coordinates (2018).

I love this so much so I'm sharing it again.

Each fraction is a pair of numbers k/n, where k is a totient of n.
The denominator n is mapped to the radius n and the number k/n is mapped to the angle 2pi*k/n.

I conceptualized and created this with R.

Quick question...

I've seen somewhere a question about (fib)²+41 always being composite, but my search-fu is failing me.

Help?

It’s so cool approaching application deadlines and having a small sense of confidence in my own abilities. I actually feel like if I found my way into a research team, I could actually contribute

Any school applicants on masto?

What’s your timeline looking like this year?

Gotta thank my friend for lending me his GRE Math Subject test study book. Looks like I’m gonna have to review a lot of Calc 2 and Complex...
Even as a math major I never wanted to see this many integrals 😩

Got to describe a favorite theorem of mine today — D_n / Z(D_n) isomorphic to D_(n/2) for n even.

Love being in a class where everyone’s motivated and hanging out to study.

Today in #mathematics news: Sir Michael Atiyah will apparently be presenting a proof of the Riemann hypothesis on Monday.

ladies picture this: you go on a date with your perfect man. he's handsome. he's smart. he's got juicy quads. he's a marxist-leninist. You go home with him to find a mint condition dxracer racing red gaming chair at his desk, wyd?

*knock knock*

"Who's there?"

How do y’all stay on track and get back on your feet after you’ve had a bad week?

diogenes of sinope would be on mastodon were he alive today.

he liked to:

- crank his hog in public
- shit in public
- tell emperors to fuck off out of his light
- shitpost to random strangers in the street (trying to find and honest man with a lantern lol)
- loved dogs, thought people should live more like dogs
- probably smoked weed

in case you wanna get an early start on tomorrow night's memes it's gonna be the billy ray cyrus tv show "Doc"

@birdman Basically, does the *derivative* of a family of functions that converge to s have to converge to the derivative of s?

Interesting claim i came across in a research seminar.

If $s_n \rightarrow s$ converges to s pointwise as n increases, then $s’_n \rightarrow w \implies w \le s’$
