Heisenberg’s idea had quickly been dubbed Unschärferelation, which transliterates to “unsharpness relationship,” but as there is really no such term in English ('blurred', 'fuzzy', 'vague' or 'ambiguous' have all been tried), the translation ended up as "the Uncertainty Principle"—when he had not used either term at…
Without going into unnecessary detail, we have built into the simulation a few telltale incoherencies—such as the idea that consciousness depends upon the brain, some logical paradoxes, and the measurement problem (etc) surrounding quantum physics. In SG the pieces are allowed to discover and reflect upon their…
‘Duh huh! That’s putting it mildly!’ Zinda purses her lips. ‘There are two problems, really. The first is that we can’t solve any hard problems. Not really. Anything that’s NP-complete. The Travelling Salesman. Pac-Man. They are all the same. All too hard. Even if we had a computer the size of the Universe! It drives…
My own field of physics is passing today through a phase of exuberant freedom, a phase of passionate prodigality. Sometimes as I listen to the conversation of my young colleagues at Princeton, I feel as if I am lost in a rain forest, with insects and birds and flowers growing all around me in intricate profusion…
I remember a talk that Von Neumann gave at Princeton around 1950, describing the glorious future which he then saw for his computers. Most of the people that he hired for his computer project in the early days were meteorologists. Meteorology was the big thing on his horizon. He said, as soon as we have good…
Now it is generally true that the very greatest scientists in each discipline are unifiers. This is especially true in physics. Newton and Einstein were supreme as unifiers. The great triumphs of physics have been triumphs of unification. We almost take it for granted that the road of progress in physics will be a…
In the year 1900 Max Planck wrote down an equation, E = hv, where E is the energy of a light wave, v is its frequency, and h is a constant which we now call Planck's constant. Planck's equation was the beginning of quantum theory. It said that energy and {22} frequency are the same thing measured in different units…
Quantum mechanics claims that there is no definite cat in the box, only a ghost, a superposition of a live cat and a dead cat. That is, until we open it and look. A measurement will collapse the system into one state or the other. So goes Schrödinger’s thought experiment. It is completely wrong, of course. A cat is a…

THE FOLLOWING IS QUOTED FROM BERGAN EVANS ON NORBERT WEINER, NUCLEAR PHYSICIST The second concept Wiener has to establish is that of entropy. Probability is a mathematical concept, coming from statistics. Entropy comes from physics. It is the assertion-- established logically and experimentally-- that the universe, by…
Causality itself is an evolved conceptual tool that simplifies, schematizes, and focuses our representation of situations. This cognitive machinery guides us to think in terms of the cause—of an outcome’s having a single cause. Yet for enlarged understanding, it is more accurate to represent outcomes as caused by an…
Here are the circumstances: source, strong light source; tell me, behind which hole will I see the electron? You say, 'Well, the reason you can't tell through which hole you're going to see the electron is, it's determined by some very complicated things back here: if I knew enough about that electron - it has…
Think of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren’t you? How else would you remember it? But here is the bombshell: you weren’t there. Not a single atom that is in…
“You turned into a cat! A small cat! You violated Conservation of Energy! That’s not just an arbitrary rule, it’s implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get ftl signaling! And cats are complicated! A human mind can’t just visualize a whole cat’s anatomy and, and…
Physics explains why no links were found. The microwaves used in cell phone transmissions do not have enough energy to break the chemical bonds of DNA, which is how cell mutations occur and cause cancer. How do we know this? Light and other parts of the electromagnetic spectrum, including microwaves, radio waves…
Once the matter created by the Big Bang cooled sufficiently, the universe consisted of a vast cloud of hydrogen atom consisting of a single proton surrounded by a single electron—along with a smattering of slightly heavier elements, including helium (with two protons) and lithium (with three). The universe at that…
I like relativity and quantum theories because I don't understand them and they make me feel as if space shifted about like a swan that can't settle, refusing to sit still and be measured; and as if the atom were an impulsive thing always changing its mind.
One might talk about the sanity of the atom the sanity of space the sanity of the electron the sanity of water— For it is all alive and has something comparable to that which we call sanity in ourselves. The only oneness is the oneness of sanity.
The stone that Dr. Johnson once kicked to demonstrate the reality of matter has become dissipated in a diffuse distribution of mathematical probabilities. The ladder that Descartes, Galileo, Newton, and Leibniz erected in order to scale the heavens rests upon a continually shifting, unstable foundation.
Webmaster has searched for a primary print source without success. Walter Isaacson likewise found no direct evidence, as he reports in Einstein (2007), 575. However, these sentences are re-quoted in a variety of books and other sources (often citing them as a remark reportedly made by Kelvin in an Address at the…
