... in order to produce an appreciable alteration in the mass due to this cause. This may, for example, be the explanation of the fact that the helium atom has not quite four times the mass of the hydrogen atom. Until,however, the nucleus theory has been more definitely tested, it would appear premature ...

Positron and electron collisions with anti-protons in strong magnetic fields
... All of the calculations reported in this paper use the Classical Trajectory Monte Carlo method. We solve for the full motion of the particles using the classical Hamilton’s equation in Cartesian coordinates. This is an approximation to the extent that quantum effects are unimportant. We do not have ...

... In the context of the general relativity theory, universality of a free fall is often referred to as the Weak Equivalence Principle (WEP). WEP is being tested with increasing sensitivity for macroscopic bodies. The best test so far confirms WEP to the accuracy of 2×10−13 (using a rotating torsion bal ...

This theorem is one important reason for introducing the Hamiltonian formalism, for it permits a geometric interpretation of classical mechanics and is crucial for ergodic theory and statistical mechanics. The analogue in quantum mechanics turns out to be that quantum mechanical ...
