OMG thank you SO MUCH!!! I've seen tons of videos, read tons of articles, researched every possible thing about spin, and THIS is the first one that actually made me understand it finally!
Thanks Eugene. Even though my job has nothing to do with Physics, I really enjoy watching your videos and get a better understanding of the amazing world around us.
Always a good day when I see a new physics video from you. Keep up the great work! I know I'll be watching a lot more of you in the upcoming months as I review for the GRE.
I’m no physics student, but I still find this kind of stuff to be fascinating. Unfortunately, for the layman like me, it’s hard to find scientific explanations for things that aren’t either way above my level or ridiculously simplified. This seems to be a perfect middle ground, and has excellent visuals! This helped me understand spin better than any other source I tried looking at. Thank you and have a great day!
I've just come across your videos for the first time today. Your animations are superb - in fact the best I've seen. I lecture in these topics myself and I will certainly be directing students to your wonderful visualizations. I've also viewed your video on entanglement and can't wait to see the rest of your brilliant and clear explanations.
Man, more people who make videos like yours need to get whatever program you use for the animations. Nice visuals. They are a work of art in themselves.
I am a physicist and I wished every student of physics was exposed to these animations to bring some clarity to some rather difficult to understand subjects, or simply subjects that required large infrastructure knowledge, excellent!!
As in the Double Slit Experiment i have to presume that the act of measuring anything like the position of an electron or the spin of an electron changes the condition of the propertie of the electron. By measuring the property, we force the electron to assume a condition. The fact that we measure the condition Spin Up the first time and Spin Down later on (after measuring it in a different direction) kinda proofs that we alter the property (read: force it to assume one of the possible conditions that we propose).... Although that's how far my understanding goes at this given point. Feel free to point out mistakes in my train of thought!
Definitely the best visuals I've ever seen for a science video on youtube. Still don't fully understand the concept but pretty sure thats just cause this concept, like most quantum mechanical concepts, is abstract af.
You are without a doubt one of the most underrated TH-camrs of all time! You could explain and simulate anything to any academic level while making it fun! I appreciate literally every video that you put out and I hope you keep making more. It is unfortunate that TH-cam's algorithms don't give enough to content creators like you and favor duller, more mundane TH-camrs like video game players and vloggers. I don't understand how people can pass over such amazing content such as yours. Forever a fan!
I love these videos. Thank you for making them. One suggestion: explain entanglement first and then offer observation as a special case of entanglement. Newcomers often get an inflated sense of ego when we first describe the effect of observation and then spend only a little time talking about entanglement. Measurement is entanglement.

I never thought I would feel this much stress and suspense in a seemingly boring physics video. But god was I wrong. Tension was at the peak when it was revealed how supernatural electron spin is my detecting their directions with the detectors. The music doubled the excitement.
Thank you Eugene, your videos are incredible! Do I understand correctly that once we perform the measurement, the cubit collapses on the always on *z-axis* to 1 or 0 ? (and x and y axis are there just to represent from which point on the sphere it could have been while in super position, before collapsing).
Wonderful.... especially the way the imaginary axes are explained is amazing... Nice imagination to understand quantum physics... Plz do cover other aspects of science too...:)
Here is a question for you: We assume that quantum mechanics is this spooky undefinable world where we can know the position of an particle or its velocity but never both. The example you show us emphasis that even more. You can only ever know the spin of an electron in one direction on the 3d axis and never more than one at a time. Furthermore we note the very weird quality of quantum physics where the state of a particle appears dependent on whether we measure it. The classic is the splitting of a photon through to holes where when we don't measure it the light shows as a wave but when we do we get a single point and the average of those points appears in the lines highlighted in that wave. In your example once we measure the spin of a particle in a direction the particle randomly changes in the other two. In both case you show the obvious nature of quantum theory where things show up as probabilities. We can't show where the particle is only where it could possibly be. The average of those events over time will reflect those probabilities very closely. The assumption is that particles can be in two places at a time and have several values or may be in several dimensions we don't see but there is never an exact finding in the universe we can see that can exist. My question is how do we know that assumption is true? My conjecture is that when we analyze how we detect the particles and forces of our world we only can sense things using the electromagnetic force of nature. While we can detect the effects of the strong or weak force in accelerators or feel the force of gravity we do not use the strong, weak or gravimetric forces to detect these things. The particles show off in accelerators are shown via photons which are carriers of the electromagnetic force. When we feel gravity we feel the push back on the atoms in our cells from the electromagnetic fields of the electromagnetic fields of the objects we are in contact with. It seem safe to conclude that all our information regarding the universe is filtered through the electromagnetic force. We can deduce an awful lot about the other three by what we can detect but is there not information we cannot perceive due to this filter. Effects within the other three forces that don't transfer to the electromagnetic spectrum in meaningful ways. Could it be that the uncertainty is not actually the fuzziness of the quantum states but the fact that the only way we have to detect changes, electromagnetic forces, by their nature must interact with the elements we are trying to observe. This would explain why we get particles when we measure which hole the photon went througn and waves when we don't The states are not the same. In one we affect the expierment through our attempt to observe and in the other we do not. This also explains why the act of measuring the other axis of electron spin means we lose information regarding the other axis. It is not that observation changes things but rather we are interacting with that electron to measure it which means we by default affect its state. Why do we assume that it is a spooky undefinable nature of quantum mechanics and not a flaw in the only way we can observe the quantum world.? I have no clue what the answer to that question is?
You put it well. The act of observation is an act of interaction and therefore results in entanglement of states and an alteration in the inherent state of a quantum particle.
classical physics, spin is represented by an arrow indicating the rate and direction of rotation. However, in quantum mechanics, spin behaves differently. While classical spin can have any value and be measured in all three dimensions simultaneously, quantum spin measurements are limited. An electron's spin can only be measured in one direction at a time, and there's a fixed length for all three spin components. Quantum spin is described by mathematical states, with two complex numbers representing probabilities. These probabilities determine the likelihood of measuring spin in various directions. When observing one spin component, the system's state changes to one where that component is certain, but others become uncertain. The video also introduces matrices associated with spin in each dimension and discusses the implications of quantum entanglement on spin states.
what if you tried to measure the spin of the particle in two different directions at the exact same time, without any nano or pictosecond [ was that what it s called? ] or anything smaller between the two measurements? or what if we were able to directly look at these particles individually?
What is the function would you consider the imaginary components of these complex numbers to have which are manipulated in these equations that make the complex aspect necessary over real numbers?
Amazing video as always! When the quantum state collapses to a 100% of one direction, let's say in this example Up, there seems to be two quantum states that both, when magnitudes squared, will give 1 as the probability. So in this visualization, there seems to be a |Up> and -|Up> state (its negative) both of which, when measured, will give the same result. If a state collapses into the physical "Up direction" state, is there a way of knowing about whether the quantum state collapsed into the positive |Up> state or the negative one? Or is there even any physical difference to these two states? A further question: for each physical direction, are there only two quantum states that correcpond to measuring that direction with 100% probability (positive and negative), or is there an infinite amount of them, with all possible complex phases? For example, are all of the following quantum states valid, all resulting a 100% probability of measuring spin in the Up direction: |Up> -|Up> i * |Up> -i * |Up> (1/sqrt(2) + i/sqrt(2) ) * |Up> etc.. And if so, is there any actual, physical differences to all of these options?
I am wondering, what are the means used to determine the direction of spin that cause or fix the probability the electron will be detected to be in any particular direction of spin? What are the X, Y and Z "instruments used?
I’ve been struggling to understand this principle in relation to fundamental particles. But this made it make so much sense. I really wish there was a way to have more of these types of animations demonstrated in classes.
