    Late 80s hairsprays and other canned aerosols were a sizeable contributor.

    They were an easy fix, and stopped being a problem almost as soon as people decided to do something. That was way before the problem reached mainstream media, so when people started talking about it, they weren’t a problem anymore. But they surely were a problem for some time.











  • But doesn’t E=mc² teach us that mass and energy are somewhat interchangeable?

    There are two ways to read that equation. Either you use the instant mass, that changes with the object’s speed and has an undefined result for anything moving at the speed of light (this is the one Einstein wrote in awe about), or you use the rest mass and that’s the half of the equation that doesn’t consider the object’s speed (this is the one everybody actually uses).

    On the second case, the complete equation is E² = (mc²)² + (pc)² where p is the momentum.

    Videogame cities are all dead and creepy… I can’t imagine what anybody finds beautiful about them.

    Of course, they are this way because they are literally designed, by a tiny number of people, and with sole focus on the player. But still, no idea why anybody can think they are beautiful.
