Must read: A Visual Introduction to Machine Learning
If you want a very quick intro to machine learning (decision trees, specifically), this page has great -I mean, great!- content. Quick read with beautiful visualizations.

Apollo 11 Code
You probably need to be an uber nerd to think this is cool, but here it is: "Original Apollo 11 guidance computer (AGC) source code, in assembly, for
Command Module (Comanche054) and Lunar Module (Luminary099)", uploaded by Chris L Garry, an intern, to github.
https://github.com/chrislgarry/Apollo-11/tree/6e8c67f53145375d48d8a1af8f85384d1b10ec51
Smithsonian Magazine article discussion the details is here.
And, to coders who are trying to fix it. This is blasphemy, stop it! That code worked fine :) It was a fairly successful operation that we haven't repeated in the last 50 years.
Here is a nice page that lets you 'replay' the whole thing, both audio and video. This one is a nerd fest too:

New Suite of Solutions to Three-Body problem
After 'discovering' Cixin Liu's Three-Body Problem trilogy, I started reading about the original problem and it's solutions. Came across the following article describing a recent set of 13 solution families:
Physicists Milovan Šuvakov and Veljko Dmitrašinović at the Institute of Physics Belgrade, discovered 13 new families of solutions to the problem, adding to the 3 families earlier. So far we have:
Recent results are described in 'Three Classes of Newtonian Three-Body Planar Periodic Orbits.'

- Lagrange-Euler family (1800's)
- Broucke-Hénon family (1970's)
- Figure-eight family (1993)
- Šuvakov-Dmitrašinović suite (2013)
Recent results are described in 'Three Classes of Newtonian Three-Body Planar Periodic Orbits.'
