The problem is that when you throw a ball -- especially a heavy one like a medicine ball -- at something like a stool, the ball will knock the stool across the room and may even have enough momentum to bounce back. You can say where the stool was, but not where it is now. ...
What happens inside the black hole is unknown; even our current theories of physics do not apply in the vicinity of a singularity. Even though we cannot see a black hole, it does have three properties that can or could be measured: Mass Electric charge Rate of rotation (angular momentum) ...
“Discovering the nature of dark matter and its properties would help us to understand the evolution of our universe, and would be an important step forward in our understanding of the fundamental laws of nature,” Dutta says. Sarah Wells ...
The goal of LHC experiments isn't to produce WIMPs directly, but to produce other particles that might decay into dark matter. This decay process, although nearly instantaneous, would allow scientists to track momentum and energy changes that would provide indirect evidence of a brand-new particle...
Based on Thomas–Fermi semi-classical model, a special methodology allows [45] to find single-electron densities even beyond electrons classical turning points in atom and use them for revealing shell-effects characteristic of many-electron quantum systems. Further development of the semi-classical/...
In the latter case, they might never find out that machine cooling actually is important. Sampling biases can be counteracted by changing the presentation of information, for instance, by making it transparent how the sample was selected [31] or by asking people to find arguments against an ...

What is an inertial frame of reference in physics? What type of relationship exists between velocity and centripetal force? How do you find time and velocity in momentum with only force and mass? What is velocity in physics? How is force expressed in terms of momentum?
where μB is Bohr magneton; g0 is the free-electron g-factor; S and L are the spin and orbital angular momentum respectively. The simulation of L is nontrivial for periodic systems and the details are given in Method section and Ref. 39. Having H(Bext) at a transverse Bext perpendicul...
In place of quantities such as position and momentum, it included complex arrays of observable energies and transition amplitudes (the probabilities of atoms undergoing a transition from one quantum state to another). This was a strategy born more out of desperation than from any philosophical ...
