Re: How to reason about the force, pressure or impulse to break something?

The seatbelt and the shotgun stock are not exact analogues. In the case of the shotgun: the necessary transfer here is only momentum, not energy. Some (mass * velocity) has to equal the momentum of the bullet. If that'a big mass, the velocity can e low. Since kinetic energy is (1/2 mass * velocity^s...

Re: 2016 US Presidential Election

Something I realised last night - in all this kerfuffle about the Russians 'hacking' the election, the part of the story where Trump actually asked for it to happen keeps being missed. I think that's reasonable - it really was a joke. A tasteless joke perhaps, but not evidence that he was involved,...
