Interesting and/or cool stuff I've come across from art, design, technology, photography, movies I've watched and liked and, occasionally, my thoughts.
There can be too much light.
Today I learned: a Kugelblitz is the (theoretical) phenomenon where the concentration of light (or heat, or radiation) is so intense that it warps spacetime enough to spawn a black hole.
Further down the same Wikipedia rabbit hole I learned of the concept of black hole starships — using black holes as an energy source for interstellar travel.
Rodeny Mullen invented the flatground ollie in 1982 based on Alan “Ollie” Gelfands no-handed airs on vert. For the uninitiated it looks like magic, the board seemingly glued to the skaters' feet. For the initiated, it feels like magic — successfully popping your first ollie is an endorphin cocktail rivaling the best.
Aathis Batia goes all sciency for Wired and shows the forces at work while popping an ollie.
