I will start with a great GIF this impressive bowling form and a even better release.
I enjoyed watching this pretty dated YouTube video featuring Warren Buffett and Bill Gates about success. I just stumbled upon this video and I have never seen any of Buffet's videos or read his work before, I enjoyed clarity in his thoughts as well as his simple way of explaining fairly complex ideas.
Few interesting discussions on Reddit, one about Why are we trying to colonize Mars. One takeaway for me from this discussion was how you don't often realize that such ambitious targets increase the rate of innovation, while solving difficult problems like these we find better solutions for our current problems. As from one of the comments:
"As Neal deGrasse Tyson said, for every dollar invested in NASA, there is a $14 economic return just from the innovation that comes out of solving problems. Pyrex bakeware came out of trying to develop rocket noses, WD-40 was the 40th attempt at making a compound that would Displace Water, that's Water Displacement attempt #40, the internet as a whole came out of a scientists who wanted a better way of linking scientific papers to the documents they cite in their bibliographies."
The other one is a /r/AskReddit thread Whats the smartest thing you've heard come out of a child's mouth?, just a nice collection about a bunch of smartass kids.
This Jupyter notebook titled How to Make Money simulates a simple economy and how money is made in an economy. I never realized that debts are good for an economy to prosper, this was something counterintuitive to me and I would really recommend playing around with this.
