Give her a quarter and cup your hands and she'll drop her balls in them.
Agreed. And being hit from the rear isn't as severe as a front-on collision, the seats after all are designed to work with accelerations in that direction.just because the Mercedes didn't total itself out over a fender bender doesn't mean it's poorly designed. I'm sure they've designed it to crumple at speeds that matter.
Nah, it's mostly convective. Hair traps air, slowing convection, and hats improve upon that. Most fabrics don't do much to block IR radiation, unless of course they're lined with tinfoil. Most materials absorb IR, then lose the energy via convection. Metals don't absorb and then re-emit EM radiation though; the photons are deflected without being absorbed -- no energy transfer to the material. Emergency blankets exploit this to great effect.. 100% of the heat bounces back at your skin.+1, although id assume the dominate method of heat exchange in that setup would be radiative, no?
