PhysicsOverflow was started in April 2014 as a physics-equivalent of MathOverflow by Rahel Knöpfel, a physics PhD at the University of Rostock, high-school student Abhimanyu Pallavi Sudhir, and Roger Cattin, a retired professor of computer science at the University of Applied Sciences, Switzerland.

Several methods of such measuring exist. In one case the increase of liquid level is registered as the object is immersed in the liquid (usually water). In the second case, the object is immersed into a vessel full of liquid (called an overflow can), causing it to overflow. Then the spilled liquid is collected and its volume measured.
For example, in the case of spheres the angle depends on the distance between the (parallel) paths of the centers of the two bodies. Any non-zero change of direction is possible: if this distance is zero the velocities are reversed in the collision; if it is close to the sum of the radii of the spheres the two bodies are only slightly deflected.
Water can be added intermittently to the bucket, which leaks out at a constant rate until empty, and will also overflow when full. The leaky bucket is an algorithm based on an analogy of how a bucket with a constant leak will overflow if either the average rate at which water is poured in exceeds the rate at which the bucket leaks or if more ...
Settling pond for iron particles at water works. Settling is the process by which particulates move towards the bottom of a liquid and form a sediment.Particles that experience a force, either due to gravity or due to centrifugal motion will tend to move in a uniform manner in the direction exerted by that force.
For example, for a rectangular cross section, with constant channel width B and channel bed elevation z b, the cross sectional area is: A = B (ζ − z b) = B h. The instantaneous water depth is h(x,t) = ζ(x,t) − z b (x), with z b (x) the bed level (i.e. elevation of the lowest point in the bed above datum, see the cross-section figure).
Authorities set on a worldwide chase to find Nicholas Alahverdian, once praised for his work as a child advocate, who has been accused of rape, abuse and fraud.
The noncommutative standard model is a proposed extension of the standard model of particle physics. The noncommutative torus, deformation of the function algebra of the ordinary torus, can be given the structure of a spectral triple. This class of examples has been studied intensively and still functions as a test case for more complicated ...
