  • Somewhere between 1926 and 1950, we gave up the concept of particles in favor of quantum fields. In this video, I explain the motivations for that to a non-physicist: my wife.

    Feynman was once asked if he could explain Quantum Electro Dynamics so that a lay person could understand it, and he replied, "No." As a certified lay person, I can say you have made some progress in that direction. Also, I have read most of Feynman's books, and they are extremely readable for those of us who are fascinated by the topic but have had nothing more than high school calculus. He was a fascinating person.

    For anyone who wants more, I suggest looking up the Douglas Robb memorial lectures by Feynman himself. He does regular quantum dynamics as well there, but in lecture 3 he goes a little bit deeper into this video's topic (quantum electrodynamics), but staying at more or less the same level of difficulty / abstraction. (Maybe a bit more concrete in its calculations, and it builds upon the former two lectures, so it's not a bad idea to watch those as well.)

    "I'm not hear for that, but ok" is exactly how I feel about particles being their own anit--particles. Like if photons are their own anti-particle why aren't we seeing them annihilate each other all the time?

    • @mrgalaxy396
      @mrgalaxy396 Рік тому +4

      The short answer is: because maths.
      Antiparticles are the same distrubance in a quantum field as regular particles. They have the same properties and same quantities for those properties with very minor differences. Antiparticles and particles even being different things is a direct result of the mathematical symmetries that describe the field.
      The reason particles and antiparticles annhilate is because they have opposite values for some property and when you add them together you remove the entire distrubance in the field and get a vacuum state. That opposite value is a result of a symmetry used tk construct that field mathematically. However, due to the way the photon field is constructed, a different symmetry result is achieved making the photon and antiphoton be the same thing, aka the photon, because mathematically they have identical properties. So there is nothing to cancel each other out mathematically here, so no annhilation. In fact, photons don't even interact with each other at all, they just pass by through each other. It's a rather peculiar field.

      @@localverse Math is just a model, an abstraction of underlying principles. These particles obey certain symmetries, we can measure and check those symmetries and see how well the model predicts them. The symmetries that photons obey when accounted for in the mathematical model produce an antiparticle identical to photons themselves in this model.

There are many types of charge (electric, color, weak, etc.). Antiparticles have opposite values in all those charges. A photon doesn't have any charges, so the only opposite for it to have is spin _orientation,_ which isn't enough to make the anti-photon its own particle. It's just a photon in a different orientation.

      Fortunately, the bonkers idea of antimatter being time-reversed matter is just a shut-up-and-calculate tool that works because of the symmetries of nature! When you "time-reverse" an electron on a feynman diagram, the other properties that also flip signs are its charge and spin, which bingo boingo turns it into its antimatter complement! :D
      It's a simple idea that feynman had that tremendously simplified the math of QCD interactions.

      It's not surprising when you consider that all observations in QFT are essentially just interactions with particles. Meaning when you are observing a field, you are affecting it and introducing additional distrubances. Otherwise how else can you observe something if you don't interact with it?
      You become coupled with that field so what you perceive is a result of you affecting that field, or rather that field being disturbed by your interaction with it.
