Spacetime curvature placemats


AP Works's Trick Mat is a placemat that mimics spacetime curvature; no word on whether or how it can be purchased, alas (though you could probably make a pretty good disposable facsimile with an inkjet printer and some vector-art software). (via Super Punch)

Novel-writing is very energy-efficient

How much energy is expended in all the keypresses made in the course of typing a novel? Not much: "With a lot of rewrites, you might expend several kilojoules—but you'd need to rewrite every word 10 times to match the energy stored in a single AA battery." [XKCD What If?]
