Prof. Morello explains why spin does not mean the particle is actually spinning. Subatomic particles like the electron, neutron, and proton have spin, which means they act like tiny bar magnets. This can be used in quantum computing applications.
We thank the UNSW School of Physics Demonstration Unit for providing the double pendulum.

the 1/sqrt2 is a 'normalization' meaning that the probability of finding the electron in any state at all must be one. So that factor is there because otherwise you'd have a 200% chance of finding an electron in any state at all. The +/- signs he discusses are associated with having electrons in the same phase or opposite phase - the best analogy is the double pendulum.

Is it possible for spin to not be a probability and only a product of the nearest price acting upon it? The hidden variable would then be the spin of the surrounding particles? I understand that there would then be no link between two pairs since it is not based off of the others spin but can’t it be because two pairs can only travel in a quantises space where the spin of the surrounding particle would effect the spin on the other side of the surrounding and so forth until it reaches the the particle in the pair and coincidentally the length between them is always in such a way so that they are two opposite spins? This is for two particle pairs and I think you could predict spins of electrons in an atom judges by their angle from a line co-linear to the radius of the nucleus and perpendicular to the net magnetic field of the nucleus

I already knew that. What I meant is that quantum mechanics is based on axioms, and so it is, that there happens stuff that noone knows "how" or "why". Okay, someone could argue that we don't see vectors coming out from objects when we talk about Newton's axioms. (If he dares to ask the question, why is Newston's law as it is). But in Physics they are not taught as axioms rather they talk about "Newton's laws". Noone questions them really...If Newton's laws were thaugth as axioms and Physicist would admit even highlight that they are models of the reality, it would be much easier to understand QM. But often they surround QM with some vague scientific mumbojumbo e.g. "the explanation is purely quantummechanical" - That means that if QM axioms are accepted as true (they are because they tend to describe reality almost properly), there exist some mathematical equation, which spin comes out of. ps.Sorry for the length

KFGChris333 I think he just means that there is not a classical explanation possible: no model that you'd recognize from every day life will suffice and give you an "intuitive" understanding. QM itself however is not synonym for "nobody knows what it is", QM is the most perfectly matching theory ever, very well defined and making accurate and precise predictions.

What is Spin ? I think the answer is phase shift (= shift in coordinate). 1. I think the de Broglie waves of multiple particles in one quantum state are connected in series, and the each wave shift msλ at the connecting point. (ms:spin quantum number, λ:wave length)Let us consider a case in which two electrons are in one quantum state [n,l,ml,ms=+1/2]. The de Broglie wave of 1st electron shifts +λ/2 in coordinate. And the de Broglie wave of 2nd electron shifts +λ/2+λ/2 in coordinate. Accordingly the two waves destructively interfere. [the Pauli exclusion principle] 2. Suppose that two electrons are moving in a single orbit, and suppose that the de Broglie wave of one electron shifts +λ/2 in coordinate and the de Broglie wave of another electron shifts -λ/2 in coordinate. The two waves have the shift of exactly one wavelength, which leads to a constructive interference of the wave, making it possible for the two particles to move in the same orbit. [the 4th quantum number] 3. The variable of wave function Φ{φez・(r ×p)} in φ direction has angular momentum r ×p. Accordingly, the shift in coordinate msλ change the angular momentum as follows: ml(h/2π)→ ml(h/2π)+ms(h/2π). I'm sorry that I'm not good at English.

Spin is not the magnetic field of the electron or other particles. Spin is an intrinsic property of elementary particles. The magnetic spin moment is determined by the spin of the particle and it tells us how the particle will behave when introduced to a magnetic field... A neutron has spin because it is a hadron. Hadrons are composite particles made up of elementary particles. Neutrons are made of quarks which in turn have their own spins. This is where the neutron, and analogously the proton, gets its spin from.

My doubt is, that the e- can also be in 1/√2( - |a> + |b>) and 1/√2(- |a> - |b>). Then why do we ignore these two states.

As a simple way to put it, you have to remember that they have magnetic dipoles. So they generate a tiny magnetic field, and the other spin tends to line up with it, just as they want to line up with the other spin... They end up oscillating forever, just like the two pendulums...

Deep Space Angel It does not have much to do with entanglement. If you look at the math, that's just how it works out : when you look at, say, two electrons, there is an interaction between their dipoles - they tend to line up. (That's a classical explanation, but then, the development for this is semi-classical : we derive the Hamiltonian from the classical formulas for the interaction between two magnetic dipoles...)

Double-pendulum = entangled state. Great analogy. Prof. Morello explains stuff better than any teacher I've ever had. I love this!

I have been trying to make sense of the superposition for sooo long, and that pendulum explanation just made it all clear, thank you so much!

Excellent analogies and explanations for general public. Wish I had had a physics prof like him in college. I hope we see more lectures for the general public from Prof. Morello.

I really think that this video is a good one! Especially because it tries to give a way to understand (or interpret) the spins. Also, this channel is becoming my favourite over Ve1, just because the acedemic level is higher. More quantum mechanics!

Awesome! I love these videos getting deep into what's more interesting. Sometimes it feels like the videos (in general, scientific divulgation videos) should get more information about the topics exposed. Thank you for this video.

This is the best video on the spin subject for a layperson that I've luckily got after watching over a dozen of videos about QM spin like "1% of information and 99% of laughing guys, stupid jokes, children toys, other nonsense"
