No, it is not vertical! The axes and the bottle is horizontal!

Let us suppose that a cylindrical bottle is on the surface of the water (filled with air for simplicity). A little spin is given to the bottle makes it rotating around the symmetry axis of the cylinder. After a while the bottle stops rotating. How to calculate the time duration of spinning?

"binning so the data would represent a frequency instead of isolated measurements. " This is, what I do not want! So the question remains!

For example I have the variables x, y and a probability distribution p(x,y). I want to approximate p(x,y) as a linear function, a plane in this case, at least somewhere in the domain. However I only have samples from the distribution. In case of big amount of data the it is easy to collect them...

I would like to solve it dynamically (with some assumptions), but my liquid is not viscous!

I think that energy and work is not useful in this case, since I would like to describe the motion in time. I have already tried. Maybe the horizontal momentum is more useful, however I do not know how to deal with the flow of the water, since the total negligence is not good, but the general...

Hi, I wonder I cannot solve the following simple problem. I really don't know what kind of equations are relevant. Imagine a rectangular tank, with vertical walls containing some water. The surface area is big. The wall of the tank is movable without friction, and its mass is negligible. All...

Yes, I know all the principles. But I need a practical example with equations, maybe a book chapter or a paper with this kind of problem. For example what kind of keyword should I search for? The distributions can be the same, but not Gaussian. Is it practically possible to calculate at all...

Are there any elaborated theory or method how to fit parameters of a function family to data given by probability distributions of data points instead of given coordinates of points precisely without error? I think this is a very general problem, I hope it is already solved. Important: I...

Is it possible practically to measure Hausdorff dimension of the surface of the Brain or the broccoli? For a broccoli Hausdorff dimension is equivalent to the so called box counting dimension, which is far more practical? I think, following the original definition Hausdorff dimension it is quite...
