Heisenberg and Schrödinger get pulled over for speeding. The cop asks Heisenberg "Do you know how fast you were going?" Heisenberg replies, "No, but we know exactly where we are!" The officer looks at him confused and says "you were going 108 miles per hour!" Heisenberg throws his arms up and cries, "Great! Now we're lost!" The officer looks over the car and asks Schrödinger if the two men have anything in the trunk. "A cat," Schrödinger replies. The cop opens the trunk and yells "Hey! This cat is dead." Schrödinger angrily replies, "Well he is now." EDIT : I've also started a science channel about everyday's common phenomenons.

The movement of the particle (any particle) moves around like a wave. Just like a molecule of H20 moves around in the ocean or lake, like a wave. Taken together, the particles move together in waves. If we stop a particle while it is jumping all around and ask it "where are you now" it gives us an answer we call measurement because we measured EXACTLY where it is this instant. But it keeps moving, so the probability is that it is probably here or there or somewhere at any given moment in time. It's the same with Waldo, in where is Waldo. We can certainly predict Waldo will need to use the restroom. So the probability of catching Waldo in the loo is pretty high, compared to other places.

This actually did help demystify it! Most analogies out there make it sound like pure magic, but the analogy of waves from a pebble thrown in water + the insights on how measurements are done and what models are used help understand what quantum physics is actually about

[@yum8666]

It still feels like magic though

[@codingphysics695]

I think, there are two reasons, why quantum mechanics is hard to unterstand: 1. The underlying math is quite complicated. For the basic concepts of classical mechanics like velocity and acceleration you only need basic calculus, with is taught at school. But the fundamentals of quantum physics involves much more math, like complex analysis and Hilbert spaces. In order to understand something like the Heisenberg uncertainty principle from the mathematical point of view, you must be at least be familiar with the Fourier transformation. 2. Quantum mechanics is counterintuitive. The concepts of classical mechanics are closely linked to our everyday experience. The orbital motion of the moon around the earth and the trajectory of an arrow are two aspects of the same thing. But in quantum mechanics we have to abandon intuitive classical concepts like the trajectory and have to replace them with abstract mathematical things like the wave function. Quantum mechanics questions our concept of reality. Physical quantities can be in a state of superposition, so that they are strictly speaking undefined before the measurement. By measuring this physical quantitity, the state of the system is irreversibly changed, simply because of the presence of this information. But without an idea what really going on at a measurement, it is difficult to get an intuitive understanding how quantum mechanics works. The solution, perhaps, is to approach quantum mechanics from a completely different angle than described in most textbooks. Instead of a particle in a potential well, one can consider an even simpler system: the qubit. A single qubit can illustrate the concept of superposition. With two qubits you get already entanglement. By learning how quantum computers work one can get an understanding about quantum mechanics even without advanced math. So, the real benefit of quantum computers could be that we use them to better understand quantum mechanics.

[@User-jr7vf]

I sometimes find myself wondering what math is more difficult, that of theory of Relativity or that of quantum mechanics. I usually end up concluding the latter is more complicated... for differential geometry is all about geometry!

You seem like you now where you are talking about. Which books would you recommend for a rigorous foundation of quantum. I wanted to try landau and lifshitz 3 volume after have a good basis of GR. Do you have other suggestions?

[@codingphysics695]

@@David-km2ie I own a copy of the Landau-Lifshitz myself and know from experience that learning from this book can be very hard. He explains many things without explicit mathematical calculation, so that much is left to the reader and you have to actively participate. But if you have worked through the entire book, then you probably have mastered quantum mechanics. (But I can only guess, because I never finished it.) If this is not your preferred learning method, then there are alternatives, such as the Cohen-Tannoudji, which I think is a bit more pedagogical.

[@codingphysics695]

@@User-jr7vf It depends how serious you want get into the theory. In principal, even good old Newtonian mechanics gets complicated if it comes to non-linear systems. However, the fundamentals of classical mechanics and special relativity can be illustrated quite nicely without math by thought experiment. But these thought experiments relies on our common sense and our intuition, which fails at unterstanding quantum mechanics. It think, since we are left in the quantum world without the guidance by our intuition, the math appears much more complicated.

Each n will be comprised of a pair of entangled batches 3. Give one of each pair to the two parties looking to communicate. 4. When one wishes to send a message to the other, they perform the double-slit experiment. i. The language is binary {0, 1}. ii. To create a zero, a batch is subjected to the double slit as per usual, creating interference. iii. For a one, a "which way" device is attached to the experimental setup, collapsing the wave. No interference. iv. This is done in the numbered sequence of batches. 5. To read the message, the other side performs the exact same experiment simultaneously(?) 6. They will see a sequence of interference or normal particle motion. 7. Convert that sequence to 0s and 1s according step 4. 8. ???? 9. Profit? Least efficient quantum communication you've ever... but you do have it

[@Tempst]

Well here's the problem You can't actually determine what's normal particle motion for an electron. It's always probabilistic. And you can't measure much for an electron with high precision other than it's spin ( Angular momentum) which is +½ or -½ and this is random. You can't get all +½ electrons or -½ electrons. It depends upon how you measure it and the spin can itself change upon measurements. Check this video by Veritaseum : kzbin.info/www/bejne/kKbZfGClmZtnbcU

Sir I have some questions :- 1. Does quantam physics apply to all electrons and protons and even to those of our body? 2. Do all of them show the property of superposition and tunneling and does uncertainty principle apply to all? If yes then how do we even exist?

[@dallyh.2960]

Answer to #1 is yes. No clue for #2.

[@chronobot2001]

Excellent point. How does the both/and randomness of QM on a micro scale turn into the complete predictability and consistency of Newtonian Physics on the macro scale? Answer: It doesn't. The QM guys can't really see or measure what is going on at a micro scale without disrupting what is happening. It's like playing marbles with a 100 ft building crane instead of your thumb. So, the QM guys use probabilities rather than direct measurements to explain what they are seeing. Their mistake is to reject the idea of cause and effect just because they cant directly measure it. Probabilities are useful, but they do not disprove individual predictable interactions.

[@synctrox9679]

Yes to both We still exist because those processes are still important for us , u have c14 atoms in you, which show radioactivity which is tunneling and compounds are formed by superposition of waves so you are alive because of superposition etc

[@michaelheines7796]

1. Absolutely, altough the effects are quite small at large scales. 2. Yes as well, they occur but quantum tunneling scales exponentially with the width of the barrier. In theory it is possible for you to run to a door rectangular barrier tunnel through it. In practise however this would mean every particle in your body would need to tunnel at the same time through a barrier of about 5 cm (or 5 10^-2 m). The exact formula scales (besides energies) like e^(-2(sqrt(2m)) (L/hbar)) plugging in some numbers for a single particle you would get m of order 10^-27 per particle and L of lets say 1, since hbar is equal to about 10^-34 we obtain e^(-2sqrt(20)10^22) which is practically zero (your calculator will probably not even say 0.0...1 but really 0). If we take but one power of 10 we would already have 5*10^-13, for 2 powers of 10, 1.5*10^-123. You can probably imagine how small this will be. Then again, to tunnel entirely every particle needs to do this, so you have to take that number to the power N, with N the amount of particles in your body (you can image about 10^25 i would say). However small quantum effects do occur, like tunneling in radioactive decay in your body. In biology models those processes are taken into account by assuming something like that can happen but not explaining why. Hope this helps

[@freddiebartlett-evans747]

Source: third year undergrad in physics. The answer to both is yes - one of the most important parts of all of quantum mechanics is the equivalence principle. This is that quantum mechanics MUST predict ‘everyday physics’ with enough particles/at large enough length scales. And it does. As systems get larger, the probabilities for ‘weird things happening’ become less and less. It becomes harder and harder to entangle multiple particles together as eventually something will disturb the system. You CAN diffract through a door but the probability is so small the universe would have to run through hundreds of billions of lifetimes before it happens (you’d also have to be going incredibly slowly). The two theories - ‘classical physics’ and quantum physics do agree - classical physics is the limit of quantum physics ie an approximation of sorts.

[@ebehdzikraa3855]

The easiest way to understand QM is by thinking of PC game analogy. Wave function as equal to rendering algorithm compiles into game code. It consist of many option & outcome directly embedded in it. The option will only materialize, either into pixel, image on screen or even different storyline, once the player come and make a decision to go that way. Otherwise, it will keep as a code. Yes, we live in the matrix

My basic understanding of Quantum physics is that it’s deterministic, meaning it changes its behavior when observed. To me, that means everything is this universe is conscious. Once science accepts and studies non-physical realities as much as tangible physical realities, quantum physics becomes less of a head-scratcher. Side note, Newton is tossing and turning in his grave

[@danielbrown1724]

@@Tony-dp1rl.....Well who crapped in your cornflakes this morning Tony “I wish I was the real deal” Stark?!! Instead of refuting everything I said, why don’t you offer an explanation of why you are refuting it. In the meantime..... If a particle knows it’s being observed and changes its behavior based on the presence of an observer, that is a pretty clear indication that the particle is conscious of the fact that it’s being watched, hence a conscious universe. Consciousness is awareness. I never said the universe was sentient, simply that it is conscious and aware of itself and its existence. Consciousness can and DOES affect physical matter. Did you realize anyone could move items with their mind just by focusing on the item and sending pure love and energy to a particular inanimate object? Telekineses, remote viewing, psychic abilities, telepathy, etc. that’s not some hooey magic, that’s connecting the mind with the unified field of consciousness that is all around us and throughout the vastness of the universe by becoming an experienced meditator.

No no... QP isn't the study of what the universe at the smallest of scales IS, it is the study of what the universe at the smallest scales DOES. It is the study of behaviours, not things. An electron isn't a "thing" in the same way that a hurricane isn't a "thing", it is a behaviour... or more accurately, a collection of behaviours that interact in such a way as to perpetuate the existence of the collection of behaviours. A hurricane isn't like a boat, sure you can point to where they both are, but a boat has a boundary, you can draw a line around it... if you stand on one side, you're in the boat, if you cross the line, you get wet. You can't draw a line around a hurricane, you can't stand just outside of it and not be affected by it... and you cannot observe it, because it's not a thing, you observe the effect that the behaviour has on things, on clouds, water, trees on beaches that get ripped up. As such, you can't point to the exact spot on the coastline where the hurricane will first hit, sure there will be the one tree that gets knocked over before the others... difficult to predict which one, not because the universe doesn't know, not because the hurricane is "random", but because it isn't a thing in a place... air is constantly being sucked in, and air is constantly being blown out, so any particular molecule of air may be part of the hurricane for a bit, but the behaviour is what is consistent. In a similar way, an electron carries a charge, but it can become dissociated from that charge if it's pushed very hard into an up quark, which turns into a down quark, causing a proton to become a neutron...the electron, free of its charge, zips away as a chargeless version of itself... an electron neutrino. So the wave function shows where something exhibits certain behaviours... it's a predictive function, it doesn't "collapse" when an interaction happens, it's that it has happened... it's no longer a prediction. The interaction of behaviours of an electron with behaviours of a photon change the behaviours going forward, so the same wave function used to predict where the interaction may happen aren't used to predict the behaviours that follow. Speed things up, take a twister instead of a hurricane, and the edges are now much more clearly defined... but they're still not edges, because a twister is also a behaviour, so you're still not safe standing right next to one, although the effect drops down much quicker either side, so you can say where it is with greater "certainty".

[@rolkstone]

you're forgetting thing and behavior duality

[@MrSolarWind]

I wonder if this approach is compatible, and how so, with another way of thinking that popped into my head previously: There are no particles, but simply waves. But we EXPERIENCE the waves as particles, according to whatever factors...similar to how we experience physically touching a solid object with our hand, yet going deeper we see that there is no actual contact and things are quite different than how we experience them. The remaining question would be...waves in what?

[@justchecking905]

A Tale of Quantum Physics When I retired a few years ago after forty some years as a physicist/scientist/engineer/college professor I decided it was time for me to develop a solid understanding of quantum physics, a.k.a. quantum mechanics. I mean how could I call myself a physicist if I didn’t know all there was to know about such an important subject. So over the past five years I spent a lot of time reading everything I could find online about QM. I read about what the most brilliant scientists had to say, from Einstein’s comment “God doesn’t play dice” to Schroedinger’s schizophrenic cat. I read about the electron double slit experiment which gives wildly different results depending on whether the outcome is being measured or not. Some scientists even claim that just being seen by a human observer causes the outcome to switch. Then I read about Richard Feynman’s chromo electrodynamics many-path formulation where every electron has an equal probability of going in any direction . . . until a measurement chooses the observed path. The credibility was stretched even further when I read that Murray Gel-man proposed that every particle was made up of even smaller components called quarks (which always occur in threes and are somehow part of ‘The Eight-Fold Way’); that David Dennison claimed that electrons, protons, neutrons, quarks, and just about every other atomic particle not only had spin (up or down), and Gel-Mann’s quarks came in three designer colors; red, blue and green. And I haven’t even brought up quantum entanglement; what Einstein called “spooky action at a distance.” I finally realized that there was no way I would ever understand it all and fretted about this until I came across the words by Richard Feynman: “I think I can safely say that nobody understands quantum mechanics. If you think you understand quantum mechanics, then you don’t.” None of the “experts” really understood it either. I could go back to claiming I was a physicist! But how could such situation happen? Well, each of the experts developed their own pet theory, but none of the hypothetical frameworks could hold together - be consistent with what we knew for sure. So the creative scientists invented whatever it took to make their theory work. Sometimes it was new (but unobserved) particles like quarks, or immeasurable properties they called spin, color, or an infinite number of multiple paths. So my final conclusion was that quantum physics/mechanics is like the story of the king’s new clothes. Every scientist saw what they wanted to see, while the truth of it all was that the king was really naked.
