[@Nafaniah]

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!

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.

[@PratapBhandari-yj2dw]

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.

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.

[@indyvisualist]

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?

[@gsftb]

So you are asking we are limited to see by the very kind of measurement people apply on particles on a small scale?

[@khalidrasouli]

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.

[@maxsamarin9002]

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?

[@cas.67656]

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?
