    *Clarification:* In my quantum animations, that is not multiple photons taking different paths. It is a _single photon_ taking multiple paths simultaneously. We're releasing only one photon at a time. Adding those phasor arrows together gives us the _probability_ of receiving a single photon at any given moment.
    *Minor Correction:* I show the paths leaving the source at the same time and arriving at the detector at different times, when it should actually be the other way around. Paths that take more time should be leaving the source earlier in order to arrive at the detector at the same time as the others. The reason we can add the phasor arrows together is because the paths arrive at the detector at the same time.

      It's a cool video, but I'm surprised with people saying it's a "great explanation" and "coherent" since these phase vectors (as in other video as well) does not seems to cancel out at all, I mean I don't understand, how do they cancel? The Sum vector for them (from the beginning of the first arrow to the end of the last one) is pretty big and I'd assume that IF they cancel THEN it would be close to zero length, this is a huge inconsistency for me... @The Science Asylum please explain this
      Nevertheless the part with removing parts of the mirror was super interesting, can this be visualized with a real-world experiment? Is a demonstration even possible?

    • @ScienceAsylum
      @ScienceAsylum  4 роки тому +88

      @@MrSenger00 The only reason they're not perfectly canceling in the video is because there's only 13 arrows in the animation. In reality, there are an infinite number of arrows. There are many arrows for paths _between_ the ones I've shown and many more arrows for paths _off screen._ They would cancel better if I considered 100 paths or 1000 paths instead of 13.

    Everyone: Mirrors are simple. Light goes in one way, it comes out another way.
    Internet plebs: Mirrors are simple. When light hits the reflective coating on the surface, it bounces at an angle according to the law of reflection.
    Nerds: Mirrors are complicated. A usually silver or similarly reflective element that is electroplated onto the surface to serve as the mirror, will absorb incoming light, and vibrate. Those atoms will begin to emit their own light, in all directions, most of which destructively interferes except for in the directions that happen to match up with the predictions of the law of reflection.

      Well, we don't need the black hole and the wall really, we just need to understand path integrals. The black hole and the wall are just a tools to do so without calling it "path integral".

      @@Lucky10279 For example, work would be a line integral of force. (in german: Linienintegral). A pathintegral is a integral of a functional with respect to a function. That's somewhat of a different thing. In the line integral we integrate over one fixed path (i.e. a vectorlike function) that basically serves as an Integration variable. A path integral on the otherhand sums the Integrand, a so called functional, a function of all possible paths, given as all possible vectorlike functions, by all these different paths, i.e. functions.
      One could say a path integral is the generalization of the line integral, but they are really just different concepts.

    Really reminded me of the great New Zealand Feynman lectures. Thank you! I was about to request this video when I saw your video on the types of reflection. So many (even more-or-less reputable) science channels get "flipping" wrong, when it is fairly obvious (and things don't come obvious to me very often). The cutting out parts of the mirror thing toward the end is really fascinating.

I visit Physics forums peopled by PhDs and I ask the kinds of questions your vidoeos answer, and your answers are clearer and seem more correct. This one gave me the glimmer of insight on an issue I've been asking for years, with no answes emerging - the fundamental reason for diffraction. WONDERFUL. It seems clear to me that your content is up with the very best in the world - Veritasium etc. I still think your treatment is holding you back, but I've come to look forward to "hey crazies" and I wish you all the best for an explosive (in a good way) career on YT.

    "Why do math with symbols when you can do it _visuallly_ instead?"
    I'm really torn about this statement. I know what you mean and I really like to get a visual understanding of unfamiliar concepts. But at the same time, I can't help but be greatful that we _can_ do math symbolically. It makes things so much more efficient. I'd drive me crazy if I had to actually draw vectors everytime I needed to add vector quantities or do the dot or cross product. I know you weren't saying that all math should be done visually, but I thought I'd share, since a lot of people don't realize how lucky we are to live in a time when so much useful mathematical notation has already been invented.
    When my algegra students get frustrated about having to learn the new notation, I tell them to imagine having to write out all the equations and compact expressions as entire paragraphs of text, and they pretty quickly get the picture (pun not intended).
