It should additionally identify routes by which complex entanglement structures and their dynamical evolution can be probed and possibly protected from decoherence in experiments. Is it possible to weed out those very rare pages that may really be of use? One possible stance is to dismiss them as mathematical artifacts with no physical relevance. The electron gets that extra energy from light falling on the atom.

The experiment is so designed that if the electron detector detects an electron it will release the poisonous gas into the room, which would prove very unfortunate for the poor cat. These rules, and the rules of quantum theory, determine how many electrons an atom has in each energy level, and in particular, how many it has in its outermost level. The details of a particular scattering process dictate the dimensionality and facets of the corresponding amplituhedron.

That thinker was Einstein and he had little company in his hesitations. For one atom, this does not give a very satisfactory answer. Scientists continue to refer to older ideas, such as Newton’s law of gravity or laws of motion as law, but no one has termed any new ideas in science as law for a very long time.

The Pauli exclusion principle states that no electron can have exactly the same characteristics as those of another electron.

If the box is then closed up again, and the electron no longer observed, its probability wave will again spread out to fill the half box, but cannot spread back into the other half of the box that was empty. It is especially easy to fool readers who want to be fooled, because they want the personal power of “creating their own reality” and are looking for a reason to believe they can do this. It is often described as a place of darkness and unparalleled torment.

We cannot keep both separability and locality. The wavefunction is just an abstract idea, which is to say that both the wavefuncton and the atom are essentially ideas, and outside of these ideas, both the wavefunction and the atom are not there. Dirac’s equation models electrons and other particles that have only half unit spin, as known from quantum mechanics. Type A individuals as a group, die earlier. Their behaviour puts them at risk for the most frequent cause of death in our society, coronary artery disease.

Thus many of the theories discussed represent mere presentations of "theoretical environments" in which more testable theories might be constructed. Also surviving would be models, such as the Copenhagen interpretation, that maintain there is no objective reality — just measurements. And those things are the uncertainty, the sort of intrinsic randomness of quantum theory, and also the fact that there's sort of an observer that seems to enter the theory as if the theory has some subjective component, and Einstein couldn't accept that.

The principle (I) states the analogical result that mental events themselves are a `prior level' of `implicit events' whose operation is needed in order to produce the potentialities for physical events. It is our ignorance of these smoothed away properties that makes a probabilistic assertion the best we can do. They explain the strange (but conventional) quantum physics of wave/particles that behave sort of like waves, and sort of like particles, but not really like either.

Werner Kutzelnigg Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone - both to the novice and to the experienced physicist. Both he and Al-Khalili forgot their lofty ambitions and returned to their day jobs. To be able to hold and embrace this paradoxical and seemingly contradictory point of view involves a higher form of logic that, instead of using an “either/or” mode of thinking, demands a “both/and” mode of thinking─the aforementioned “four-valued logic.” This form of thinking is a reflection of the deeper wholeness that quantum physics is revealing, a wholeness that is fundamental to the universe and intrinsically existing within and as ourselves.

That, in a nutshell, is the Measurement Problem in quantum mechanics; any interpretation of the theory, any detailed story about what the world is like according to quantum mechanics, and in particular those bits of the world in which measurements are going on, has to grapple with it. Instead of measuring the linear polarization states used to violate Bell’s inequality they looked for correlations between elliptical polarizations – combinations of linear and circular states.

A Jungian analyst sent me a scathing email, saying how dare I quote Jung, that I had no right to quote Jung because I wasn’t an officially trained and certified Jungian analyst. [x] This is reminiscent of when I refer, in my recent book Dispelling Wetiko: Breaking the Curse of Evil, to how the wetiko virus can usurp the healthy parts of the psyche into its service; this inner process of the psyche is playing out─and revealing itself─through the medium of the outside world. [xi] Interestingly, what indigenous people call “wetiko,” (which I write about in Dispelling Wetiko ) is a psychic form of blindness, which in its self-deception believes itself to be sighted.
