  Ho letto i primi due libri della trilogia e fra pochi giorni inizierò l ultimo. Testi di una gioia assoluta, dove si equilibrano con garbo i fatti storici, la cronaca militare, le scelte tattiche e strategiche, le curiosità e qualche aneddoto ben piazzato. Più arioso e leggero del pur grandissimo liddell hart e del tecnicissimo hastings nonché dei tanti altri che rendono la mia pensione un vivere fantastico.

  When you dont looking at stuff is vave function because you see whole distribution, aka all possible states at the same time smeared out creating an appearance form (atom, molecules, stuff). But when you measure you take a slice at a specific time, so of course when you look you see only a certain state which looks like particle not wave. So that's that I agine a propeller of an old airplane. When it rotates it seemed like a disk, but when it stops you see it's only two blades. On micro level of this subatomic particles the time frames we talk are so small or if you will do short that you see the element in all possible.positions. but when you measure it's location of course you take away time completely and you can see the stuff at only a specific position. That's all. So not sure what's the big confusion. In those small subatomic levels time frames are so small that then can even reverse in time, hence stuff seems to pop in from nothing and pop out into nothing. That's when it actually goes back in time

  Being the physics nitwit I am, my problem with the "many worlds" notion is: when opening the box to find the cat (with all its electrons) asleep, why/how would that cause that entire scene (including all of its electrons) to duplicate itself into existence with a cat that's awake at the moment of opening that box, and does this include the lab the box was placed in; the building; the street or the entire town, country; planet? Or, in short: no matter the electron's form or state, where do the extra electrons come from that make up the other cat, its box and researcher who opened it etc. etc. ? If anyone reading this, could and would try to point out the flaw in this question of mine, I'd very much appreciate it!

  Dear Professor, Time-space, is simply motion or relative velocity anything else in the geometric universe? If space is contracted to a certain level where the velocity of any object can be attained the velocity of light then how gravity can be defined? Is gravity simply energy in this time-space while gravity is mass-related in classical mechanics

  Dear Professor, Whenever not looking it seems like a wave function or energy but whenever looking, it looks like a particle. Does it mean visible things are matter while twin invisible things are energy? So, matter (particle) -energy (light) entangling; both the gravitational field (mass associated) and EM field (charged particle, electron) as conservative energies hold the whole transformation and conservation of energy in the universe. (Because the light and electron similarity in the double slit experiment and the quantum phenomena (particle and wave nature) make them alike and accepting! )

  The moment a particle is a wave; it has to be a conscious wave! Nicola Tesla states, “If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration” Gravity is the conscious attraction among waves to create the illusion of particles, and creates our experience-able Universe. Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness". Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely. We are "It", experiencing our infinite possibilities in our finite moment. Our job is to make it interesting!

I have been trying to describe the “U” shape wave that is produced in my model. The “U” shape wave is produced as the loading increases/ just before the wave function shifts to the next higher energy level. Your viewers might be interested in watching the test video the model.

  No, he doesn't know more than you, even though he may be smarter on average. We know exactly where this nonsense comes from. If you read Everett's thesis, which is the origin of MWI, then you will find that he misunderstood the mathematics of the Copenhagen interpretation in the second sentence of that document. What follows is a giant error based on that misunderstanding.

  @@kas8131 Nothing. This is just utter bullshit. If you want to understand quantum mechanics then you will have to learn the Copenhagen interpretation inside and out. The usual textbooks are of not much help, I am afraid. They are causing a lot of confusion, actually. The problem stems from the historical development. Planck and Einstein correctly identified field quantization as the cause of all the radiation and matter in the universe. Both immediately got cold feet and tried to explain what they had learned with semi-classical models. Einstein, in particular, was adamant (and completely wrong) that quanta had to be Newtonian corpuscles. Because relativistic field theory is very hard, it was impossible to develop in the early years, so people tried to bootstrap their way up through a non-relativistic model that you know as the Schroedinger equation. The SE describes reversible energy transfers in a quantum system (or, better, in an ensemble of quantum systems). That, of course, is not enough. It leads to the problem that Schroedinger was pointing out with his cat in the box Gedankenexperiment. How can reversible dynamic lead to classical outcomes? The answer is that it can't. That's why Copenhagen uses a second formula named after Born to predict the dynamics of irreversible energy transfers between two systems: the quantum system and the measurement system. In totality Copenhagen is an irreducible whole: reversible, unitary dynamics in closed systems, the Born rule in irreversible energy exchanges with the environment. It's clean, it's beautiful, it works. It also makes perfect sense once you understand that nature is, at the core, irreversible. All of reality is caused by that irreversibility which leads to long term memory. It's not caused by some magical splitting of the universe in branches. Going back to history: this irreversibility aspect can be found in some papers of Heisenberg from around 1927, I believe and then in an article by Mott from 1929. But then enters a mathematician called von Neumann around 1931 and he writes a beautiful book about the solution theory of the Schroedinger equation that strips all these physical insights away. What he leaves you with is a handful of linear algebra and functional analysis that is void of any obvious physical meaning. That's what we are still teaching in QM 101 classrooms in university. Most students leave those classrooms knowing how to calculate quantum mechanics, but they don't have the slightest clue why the calculations work the way they work. Enter absolutely clueless people like Everett and they mess even that math up like there is no tomorrow. None of it was intended this way, but to find that out you have to go back to Heisenberg's matrix mechanics papers and read them word for word and symbol for symbol.

  ⁠I want to note that this feeling of “too much we don’t know” is just vibes. Many-worlds is named in a way that people think many worlds is an assumption instead of a consequence. If the many worlds was an assumption, then it would count against it. Any consequence of premises you already accept doesn’t cost you extra probability, you get it for free. What Carroll said about Many worlds being the simplest interpretation wasn’t just his opinion, physicists agree that it makes the fewest assumptions. Other interpretations like Copenhagen tack on unnecessary assumption that are themselves not well posed and furthermore don’t explain anything new and just fit with our sensibilities. Carrol talked about this. He also said that the issue with many worlds is that it farther removed from our everyday experience. There are 0 mathematical problems with many worlds. Everything is well defined. It is debatable that it is even an interpretation. If we lived in a different world without quantum mechanics, and mathematicians discovered this cool mathematical topic which extended probability theory to complex number, no one would think of privileging certain paths, and no one would think of privileging a certain group of particles (observer). At the most fundamental level, the laws of physics make no reference to cats, nor do they to the arrow of time. Also for many worlds, there only is one wave function, not many for each of the ‘worlds’. It’s so bare bones that it doesn’t make reference to decoherence or how worlds split or that there are even separate worlds. What carrol says is that to truly understand quantum mechanics, we gotta cut away unnecessary assumptions and be able to derive them as consequences. Mathematicians do this too. You gain a better understanding of a topic if you are able to remove unnecessary assumptions down to the bare minimum.
