I ran this experiment to find out what a gun would look like while shooting under water. Turns out to be quite interesting. The muzzle blast is NOT spherical as I first assumed.

That's really cool! Are you the guy in the video?
 
Yep, that's me.
 
Kk. I'd link a video of my own, but I don't think the physics of my cat being spun around on a hardwood floor is that interesting.

Ah, the magic of embedding. I'm an idiot.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
