comment Meaning and application of convolution or deconvolution in physical sciences
I think this question is too broad to be answered correctly. We will just have an endless list ... Why are you asking ?

comment Why does the water level equalize in a series of tubes?
No because a fluid cannot sustain transverse constraints. You have to consider only the water just on top of the point (infinitesimal volume) where you want to have the pressure. The force exerted by the water is compensated by the wall of the pipe when they are not parallel.

comment Why does the water level equalize in a series of tubes?
@Claudiu: The weight has everything to do with the problem, it is "h" in the notation I used. Regarding your second question, pressure is exerted by one slice on another but it is not "additive".

comment Energy of the electron-muon reaction
@voix: if you need a more precise than this one, you should first explain why you introduced the intermediate states, and why you think it is "2*140 MeV".

comment Will a ball slide down a lumpy hill over the same path it rolls down the hill?
"Maybe I stopped too soon.": I think you did, this case altough at first being non-holonomic can be put in a holonomic form quite easily.

I meant "wave equation" to mean "not a field equation". I'll have a look at your references, thanks.

comment Material resistency to lasers beam
So it's not the duty cycle but the peak power. Duty cycle is "time on" over "total time".

comment Why doesn't a bike/bicycle fall if going with a high speed?
@Adrian: you are saying "inertia" because... there is no force... In the case of the rope, the rope is providing a centripetal force.
