Unfriendly reminder that in America it’s reasonable to say an unarmed black kid deserved to be shot six times because he might have robbed a convenience store, but a white kid shouldn’t be kicked off the high school football team just because he violently raped a girl.
A handy guide I wrote and illustrated for writers doing fic set at Hogwarts who want to know where everything is in relation to everything else. Inspired by the sad dearth of decent official maps from JK, it’s a first-person walk-through of Hogwarts imagined as if I was a Prefect handing out pamphlets to all the poor ickle firsties. ^_^’
A Leidenfrost droplet impregnated with hydrophilic beads hovers on a thin film of its own vapor. The Leidenfrost effect occurs when a liquid touches a solid surface much, much hotter than its boiling point. Instead of boiling entirely away, part of the liquid vaporizes and the remaining liquid survives for extended periods while the vapor layer insulates it from the hot surface. Hydrophilic beads inserted into Leidenfrost water droplets initially sink and are completely enveloped by the liquid. But, as the drop evaporates, the beads self-organize, forming a monolayer that coats the surface of the drop. The outer surface of the beads drys out, trapping the beads and causing the evaporation rate to slow because less liquid is exposed. (Photo credit: L. Maquet et al.; research paper - pdf)
