Advanced Sci News @AdvSciNews Researchers develop a dual-faced chain mail structure that consists of 3D re-entrant unit cells. It does a spectacular job of protecting a conical flask from damage while being dropped from height 20 times. Check it out: http://ow.ly/lIaR50Olo8f https://pic.twitter.com/ebHu717OkG Replying to @AdvSciNews Great work! These force and energy networks are very useful

CrashCourse: Binary and Multiple Stars: Crash Course Astronomy #34 at https://www.youtube.com/watch?v=pIFiCLhJmig I think you will find that many of the larger black holes are black, but not singularities. Look at the complex orbits of the stars around our own central black hole. They are complex, intricate, interweaving, but not chaotic and explosive. There are lots of

Flammable Maths: An Insane Approach! The Fresnel integrals: sin(x^2) and cos(x^2) without complex analysis at https://www.youtube.com/watch?v=iCwiDPL3EMI Writing math by hand is a bad thing to do to new generations. Get a decent symbolic math editor/solver and at least make the symbols standard. Do you trust programmers who make canned math manipulation tools, or some old guy

Anton Petrov: Incredible Advances In Nuclear Stirling Engines For Space Exploration at https://www.youtube.com/watch?v=chv6_seOaWw Little bits of power for communications and sensors is a start, but the real improvements will be when nuclear and atomic power sources (using “nuclear fuels”, “atomic fuels) are applied to high power things like transportation, mining, processing. And by processing, I mean

Chaos in the Cosmos: The mysteries and wonders of gravitation – what truly is gravity? Here’s an attempt to explain! at https://www.youtube.com/watch?v=KaOU8BBlcdw I suggest you focus more on the gravitational potential, rather than the gravitational acceleration. The acceleration field is the vector gradient of the potential field. And the potential field for the earth, sun, moon,
