... (a) In this universe laws are not constant in time. As time progresses electric charges increase with time. The spring shown compresses – building potential energy (not conserved) – this could be released to drive an engine. (b) An electric field is placed across this universe – making space anisotr ...

... Because the force on the alpha particle by the electric eld is in the same direction as the velocity of the particle, then the particle will speed up as it travels toward the negatively charged plate. As a result, its kinetic energy increases. Conservation of Energy tells us that this must be accom ...

1 Heisenberg Uncertainty Principle
... Roughly, if < x|Ψ > has a narrow distribution, then < p|Ψ > will have a spread out distribution and vice versa. Heisenberg’s original paper on uncertainty concerned a much more physical picture. The example he used was that of determining the location of an electron with an uncertainty δx, by having ...
