Re: How to reason about the force, pressure or impulse to break something?
If you fire a shotgun, it accellerates over some period of time. When it's pressed against your shoulder, your body receives the energy over that period, when there's a gap, the accellerated gun slams into your shoulder and delivers all of the energy over a much shorter timespan. When the stock is ...

Re: In other news... (humorous news items)
Scientific progress is exponential, not linear. Please offer a rigorous definition of 'scientific progress' that has a clear metric that can be measured. My point about the scientific method is that advances stack upon each other in a way they don't in a non-scientific environment - eg. a religious...

Re: How to reason about the force, pressure or impulse to break something?
The proper way to fire a shotgun is to have the stock pressed right against your shoulder when you fire. If there is a gap between the two, the recoil of the shotgun can hurt your shoulder. Everything is identical in these two situations except the distance between the shotgun and you, so why are th...
