    To everyone asking about the quantum eraser experiment, I promise Myth #3 is still a myth. *A conscious mind is still not required.* The more complicated the experiment, the harder it is to see this though. The quantum eraser experiment is made more complicated by using entangled particles. Even in the PBS Space Time video about it, he clarifies this at 1 min 51 sec: czcams.com/video/8ORLN_KwAgs/video.htmlm51s

      So an observation in the language of physics means something quite different than the word observation does in ordinary English.
      I'm guessing an observation on the atomic level is any interaction between particles, or maybe just certain kinds interactions.
      Or maybe I'm just misunderstanding entirely.

Yes, this video is specifically about myths and dispelling them, but to a large extent, every video on this channel has a mythbusting element to it. I learn so much from this channel. The format is so concise, he fits a lot of information into short videos and with the clones serving as interlocutors, the information is made very digestible.

      Its not that a wave is a particle or a particle is a wave, you can not have something be two things at once that contradicts the laws of mathematical function. So if you assume a duality idea then your idea is not a function and thus nondeferentiable and noncontinous therefore calculus falls apart. Thats why we have to see it as a particle or a wave so that calculus can be useful but not at the same time.

      From a philosophical point of view, I can understand your point. That is, in some sense he oversteps and claims the universe exists apart from observers which is itself an unscientific, unfalsifiable claim. That said, it is useful for scientists to assume this and conduct experiments as such. But strictly speaking, it is a metaphysical claim that can never be evidenced nor disproven. That said, his point that quantum mechanics functions as a mathematical theory apart from observers is now generally accepted by quantum physicists.

      1) From what I understand, Eric Weinstein isn't the most reputable physicist. I don't know many details, but he has a bad reputation.
      2) I wouldn't really agree with what he said about quantum physics. _All_ answers to quantum mechanical questions are probabilistic answers. It's just that some probabilities are narrow enough to _appear_ deterministic.
      3) There are no bad questions. All questions are good. It's the intention and expectations behind the question that could possibly be bad.

I like the treatment of the third as well, but I'm not sure what Consciousness is so it's hard to tell whether it's important or not until there's the definition. A lot of biologists tell me there is no such thing as consciousness. Stuart Hameroff is famous for saying that as a anesthesiologist he must turn off consciousness during an operation and if you can turn it off it must be something. Rodger Penrose thinks consciousness comes from Qquantum Bbehavior. Who knows? But what you're really addressing is the misconceptions about the double slit in such experiments where people assume that by measurement a conscience agent has modified the behavior of the particles and there I wholeheartedly agree with your interpretation.

    @vacuumdiagrams652 Před 5 lety +66

    Sorry to be that guy, but this video is missing the corollary to Myth #1: particles never _truly_ behave like objects, but also never truly behave like waves! The wavelike behavior of quantum particles is never quite the same as that of ordinary classical waves, and this is clearest for experiments with single particles.
    I share some of the frustration with the concept of wave particle duality because it often hinders more than helps (and resulting confusions sometimes find their way even into high profile journals), but there's a core of truth to it, which should be understood in terms of the complementarity principle. Quantum particles share properties with both ordinary classical particles and ordinary classical waves, but such properties are never manifest in the same experiment. That's the core.
    With regards to the second myth, I have a somewhat more serious contention. The language you used was necessarily vague, so I'm not super sure what you meant, but it should be emphasized that the idea of collapse has no neat dynamical solution as the picture of a photon "changing the wavefunction" of an electron implies. The state of the electron after the interaction is still a superposition of position states, and thus delocalized, but now it is entangled with the photon, so that more properly we should only speak of the electron+photon combined state. Once the state of the _photon_ is measured, hopefully by the physicist who set up the experiment, then we finally have a collapse. It happens when the observer learns something new about the system and updates the quantum state, his book-keeping device.
    This is ok and doesn't imply in magical "mind over matter" quantum magic because the quantum state is not a physical object per se. It's a calculational tool that codifies the experimenter's knowledge of the system. Because it is a quantum system, it behaves in classically strange ways, but the state really is just a thinking tool. What can be surprising is that this is true modulo some trivial corrections even if you "interpret" quantum mechanics in some nonstandard way!

      Nah he couldn't predict the future because of hidden variables like the total amount of objects in the solar system, total number of stars in the galaxy, etc. The uncertainty principle is one of the many variables that has to be accounted for when predicted the future to an exact. If you want to predict the future of everything to be exact (which is impossible due to the amount of variables that are needed that we can't possibly get) you would have to know exactly how many particles are, where they are, and all of the energy content of each particle (by energy content I mean literally all the internal kinetic energy, the kinetic energy of the combined particles of larger objects and all of the potential energy). Which this somewhat has to do with the uncertainty principal but that would only matter once we have found every particle

      @@aalmadoestado1169 According to this science asylum video, the higher the frequency of the photon, the sharper is the wave of the electron. The animation seems to say that the peak intensity increase and bandwidth (spread of frequency) decrease with high energy photon.
      The uncertainty principle should not be extended to vast macroscopic dynamic like stars and planet.
      All it says is exactly what electrical engineers know about high frequency waves: if your wave is slow, you can't measure with high precision. Visible light is about 500 tera hertz. Compared to the computer clock of 5 ghz, you need to multiply by 100 to get 500 ghz, then multiply by 1000 to reach the frequency of green light.
      Blue ray disk can store more than the original cd format that used infrared because blue light can be concentrated to a smaller spot. Uv would be better and x ray disk even more.
      Higher frequency give better precision but timing, phase, becomes less precise. That is the electrical engineer way to intuitively clarify the obscur concept of uncertainty.

    Hey, the one question left hanging for me is this: when you say electrons are waves, does this mean each of them is a "wave", or that groups of them travel in waves? This is always hard for me to grasp, because all other examples of "waves" that I can relate to are waves of some substance, like air or water... the word wave always describes a behavior of those substances, caused by some disturbance of existing matter. So I don't know how to conceptualize a single quantum particle as a "wave"; i don't know what that means; I know their behavior might be described mathematically as a wave, but how to we grasp the idea that an individual piece of matter, a quantum "particle", is by itself a "wave"?

      Lol, he's lying because he did not respond to the question - yet? What kind of logic is that?

      It's the double slit experiment however using photons instead of electrons. when they fired the photons through the slit it would pass though a crystal that would split the photon into entangled pairs (one photon goes in two entangled ones come out). As you may know when particles are entangled what happens to one happens to the other (some what). After being entangled one photon would go to the wall and the other one would go to be measured. The experiment was set up so that the the photon that is to be measured would only be observed after its entangled partner hit the wall letting the researchers know which slit the photon went through. However the photons still acted like a particle even though they were only observed and measured after the entangled partner hit the wall.
      They tried this experiment again however this time they scrambled half of the information so they wouldn't know what half of the photons were doing. the results showed that only the photons that were scrambled acted as a wave and showed and interference pattern while the ones that weren't didn't. all photons were measured and went through the same process but only the ones that were intentionally scrambled acted as waves while the ones that we still had information on didn't.
      I don't know if i explained this well enough so here's a link for you

      and the crystal they used us called an beta barium borate crystal

      I know these aren't exactly scholarly sources but this is how I've been learning about this stuff for the past month and its not to different from the science asylum so eh.

      I think perhaps you didn’t get the idea. There are no photons, there are only events and the noisy fields that cause them. How do you know there is just one photon going from one place to another when all you actually saw was a single event? But still, we would like an explanation, so we think to ourselves this is quantum FIELD theory, not quantum particle theory; with that in hand, we can think about how a field could cause events. BUT it can’t be a simple classical field, there has to be noise so that the avalanche events that happen in Avalanche PhotoDiodes happen randomly, according to some statistics, not one precisely every second. Think about it, and perhaps also see my channel, where my first video tells an approximately similar story. Not exactly, but similar. My video production is not remotely close to as funny or good as you’ve seen here, of course. There are gaps in the story, but I personally find it cleaner to invoke fields than to invoke photons, particles, objects as causes.
