3x+1 Unsolved Math Problem https://youtu.be/094y1Z2wpJg

u/rodrigo.siqueira

Paul Erdős said about the Collatz conjecture: "Mathematics may not be ready for such problems." He also offered US$500 for its solution. https://en.wikipedia.org/wiki/Collatz_conjec…
u/New_Core

I tried to visualize something with the Collatz Conjecture a few weeks ago but I didnt come up with anything good.. I bet someone can do some nice stuff with it here.
u/lewdev

Yeah, I figured there's a way to build out visuals like the ones in the video. I just did a quick one to get started. Math is a great inspiration for dweets.
u/smtsjhr

neat! some more inspiration for visualizing Collats here: https://youtu.be/RzQE2Q7lsT4
