The Relation between Mathematics and Physics
... Thus according to quantum mechanics we need, for a complete description of the universe, not only the laws of motion and the initial conditions, but also information about which quantum jump occurs in each case when a quantum jump does occur. The latter information must be included, together with th ...

On Many-Minds Interpretations of Quantum Theory
... experimental evidence for any breakdown in quantum theory, nor of any alternative theory which is not both ad hoc and incompatible with special relativity, these assertions may seem plausible (cf. Deutsch 1996). It is certainly the case that, at least over short time intervals, quantum states can be ...

Quantum Interference Experiments
... half-silvered mirror. Then we have a device that randomly either puts the second halfsilvered mirror in place or removes it. This experiment has actually been performed. In other words we don’t decide what kind of experiment it is until the photon has either taken the bottom or the top paths. Sure e ...

Quantum Mechanics Basics
... We cannot predict the outcome of a single experiment! We can predict outcome of a collection of single experiments on identically prepared systems, simply called “experiment” or “observation”! Born interpretation : The quantity |ψ(x)|2 dx gives the probability that the particle is found between x an ...

Miracles, Materialism, and Quantum Mechanics

Bohr Particles properties cannot be assigned values independent of measurement. Measurement collapses the wavefunction. “Observations not only distur ...

1 Heisenberg Uncertainty Principle
... A question that has been studied ever since Heisenberg’s original paper is whether a precise inequality can be established for the case where actual measurements are made on a quantum system. As of October, 2013, this has not been definitively settled, but we can discuss the general framework present ...

Quantum Dots - Paula Schales Art

Adding Shells to Quantum Dots capping a core quantum dot with a shell (several atomic layers of an inorganic wide band semiconductor) reduces nonradiative recombination and results in brighter emission, provided the shell is of a different semiconductor material with a wider bandgap than the core s ...
