This is one of these videos where it's cool, then kinda lulls in the center, but the pay-off at the end is totally worth it.

When newly-minted Nobel Prize winner Roger Penrose riffed on very weird physics with Joe Rogan (2018)
Yesterday, Oxford University mathematician Roger Penrose was awarded a Nobel Prize for proving that black holes could exist. In the December 16, 2018 episode of the Joe Rogan Experience, Penrose riffed on weird physics, cosmology, extraterrestrial intelligence, and quantum consciousness.

Here's a faster way to empty a bottle or jug
If you swirl a narrow-necked container to get the liquid inside moving in a vortex, the liquid will pour out much faster. The vortex allows air to flow in as liquid flows out, avoiding that inefficient glug-glug of alternating air and water. Image: YouTube / Mad Russian Scientist READ THE REST
The Bouguer gravity anomaly means that gravity is not evenly distributed
I just learned about the Bouguer gravity anomaly, which the US Geological Survey defines as: Measurements of the gravitational field vary slightly from place to place due to the composition and structure of Earth's crust. This digital grid describes the complete Bouguer gravity anomaly for the conterminous US. For example, here's a map of the… READ THE REST

This ultimate survival bag is the thinking person's disaster prep — and it's $30 off
It used to be that go bags were almost exclusively reserved for emergency responders, journalists, and those very select few who might have to drop everything and run somewhere at a moment's notice. Maybe it's a sign of our tumultuous times, but it feels like almost everyone now has their bag of emergency supplies and… READ THE REST
This self-driving truck kit is one of the coolest STEM gifts an inquisitive kid could ever get
Don't look now, but that car next to you on the road may not have a driver. Thankfully, with the advent of the self-driving vehicle, that's not the panic-inducing moment it used to be. A self-driving shuttle has been ferrying customers in Las Vegas for three years. Tesla head Elon Musk says beta testing on… READ THE REST
