What causes the snapping sound when a towel is snapped? I'm hoping that no one here has seen this before. I already know the answer.

Then why ask? Is this just some stupid way of showing off?

(And why in the world should we believe you "already know" just because you say so?)
 
I didn't figure out the problem, someone just told it to me along with the answer so I'm not showing off. The reason I posted this question is that the answer turns out to be very interesting. If you want, I'll private message you the answer and you can tell me if you think it's worth posting.

Correct, as you already know. The version I heard involved a whip. I thought changing it to a towel would make it tougher. Oh well.
 
Okay, this thread wasn't too productuve. Anyone know who to make one of those "death whip towels"? Ouch!
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

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...
