Ville Hietala flying into a tight bend in Stalheimskleiva
Because of the weight of the ends of the forks, and how they’re distributed behind the penny (closer to the glass), the center of gravity of the whole system is actually shifted quite significantly. If I’m right, it would actually have to be right where the penny meets the glass. This mean, in a sense, all the “weight” of the system of the forks and penny is resting right on that point, rather than out in the air, so if you balance it, it’ll be stable on the glass.
The difference between Science and Engineering.

As close as you will ever be to a nuclear explosion
THIS IS FUCKING TERRIFYING
No thank you.
The columns of smoke in the foreground are telephone poles boiling
This is way cooler to look at than it should be
Science side of Tumblr would like to add:
Heat is generally transmitted in 3 forms: conduction, convection, radiation.
The fact that the telephone poles and wires are boiling away well before the shockwave hits them indicates that the heat from the explosion has not reached them by convection (much slower than the speed of sound) or by conduction (at best, comparable to the speed of sound), but purely by radiation. In other words: the explosion is bright enough to boil everything.
reblogging again for what engineer—cat said
The most fun. Mark Nisbet photo from my Concrete Wave Magazine interview.
