Quantum events have a way of just happening, without any cause, as when a radioactive atom decays at a random time. Even the quantum vacuum is not an inert void, but is boiling with quantum fluctuations. In our macroscopic world, we are used to energy conservation, but in the quantum realm this holds only on average. Energy fluctuations out of nothing create short-lived particle-antiparticle pairs, which is why the vacuum is not emptiness but a sea of transient particles. An uncaused beginning, even out of nothing, for spacetime is no great leap of the imagination.
There can never be two or more equivalent electrons in an atom, for which in a strong field the values of all the quantum numbers n, k1, k2 and m are the same. If an electron is present, for which these quantum numbers (in an external field) have definite values, then this state is 'occupied.'
Judaism is much more communal, and partly as a consequence of my religious switch, I am increasingly more suspicous of my previous view that what people do in the privacy of their own home is their business alone.
The quantum fluctuations within a zero-point field can start the process that builds the process, which builds into matter, an irreversible process. We have some evidence that suggests that. We don't have a Big Bang, but we have a lot of little pops! A continuous set of little pops!
Quantum field theory, which was born just fifty years ago from the marriage of quantum mechanics with relativity, is a beautiful but not very robust child.
My own interest in basic aspects of electron transfer between metal complexes became active only after I came to the University of Chicago in 1946.
The point is that these decisions they've made are partly for your convenience and partly for theirs and partly out of stereotypes that they carry with them from the conventions of the computer field.
I think the Romans must have aggravated one another very much, with their noses. Perhaps, they became the restless people they were, in consequence.
This is due partly to the fact that Americans are much better fed than Europeans, and partly to the undeveloped resources of a new country, but more largely to our climate, which acts as a constant stimulus.
We are the product of quantum fluctuations in the very early universe.
You've heard me talk about the quantum realm in Ant-Man which was certainly designed for that movie and for that story to take the notion of somebody who has the ability to shrink to another level we've never seen before, but as we were doing that, and studying it and talking to the science advisors who are always more than willing to spend an afternoon with us and talk about these amazing things - the quantum realm is another dimension.
The considerations upon which expectations of prospective yields are based are partly existing facts which we can assume to be known more or less for certain, and partly future events which can only be forecasted with more or less confidence.
What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.
The problem is that replacement of Quantum Mechanics by Quantum Field Theory is still very demanding.
It goes to establish a just and permanent principle of trade which puts an end to all serious fluctuations in prices and consequently, to all the insecurity and ruin which these fluctuations produce; and to build up those who are already ruined.
Clearly older women and especially older women who have led an active life or elder women who successfully maneuver through their own family life have so much to teach us about sharing, patience, and wisdom.
