      #I have four questions about neutrons and low-power bosons
      The first question is whether all the short-lived particles will be converted into weak Guo bosons
      Or only the neutron decomposes into a weak force
      The second question is about primary particles
      Is neutrino composed of fluctuations in quantum vacuum as well?
      The third question, how does the neutrino form during nuclear fusion in the sun?
      Does nuclear fusion lead to the loss of part of the energy?
      the fourth question
      Is this neutrino the lost energy during the nuclear fusion process?
      We hope that you send the four questions to physicists
      Please post the answers in science websites in a web browser

      Feynman would disagree. You can see a pretty flower, and enjoy it at this level without thinking about electrons jumping onto and from energy states as they are hit by photons, emitting a specific wavelength you percieve as color. Even if you somehow end up thinking about electrons, you are then not thinking about how evolution shaped this specific flower to attract its pollinator, how the local geology made it possible for this flower to grow, how this was all started because something somewhere exploded and matter got pulled together by gravity forming a planet with active geology...
      The point is, the depth of your understanding of something is not important, you cannot think about it all at once,
      and at any time, you are left trapped experiencing complexity and beauty at a given level.
      And there is more beauty and elegance to be found at each level of understanding.

      Gromov has this lovely quote to the effect of 'anything worth proving in mathematics just shouldn't be true.' I think that it is important to keep in mind that we never truly understand something in mathematics, we only find alternate ways of looking at it.

      @cinemarat1834 4 роки тому +2

      @@ryPish well of course if you try to apply it in general terms you'll find that it's not always true. It's true mostly for more abstract concepts that the more you understand it the less beautiful it is because an abstract concept doesn't have the same direct visual stimulation as looking at a flower, so that's just a bad analogy.

      @twenty-fifth420 4 роки тому +1

      Sort of the reason I love writing personally.
      I dont always understand what I write and that is okay, I am only human. I mean that in a sense that when writing, we have to display information in a easily accessible but with a bias, either a narrative one or a thematic one.
      But once you accept that, the more you write and imperfect it may be, the more beautiful it is.
      As counterintuitive as that sounds, I think there is a balance of understanding and aesthetics personally.
      Idk, maybe I am looking into it. The take is also just beautiful. I suck at math, but glad to know mathematics can normalize beauty because I sure as hell cant understand it.

    I remember in my first semester of high school, I had decided that I wanted to study mathematics. I was horrible at it, I didn't know anything, and I got the worst grades (C's and D's). I gave up a couple of times, but now I'm getting top grades in topics like complex analysis, real analysis, and partial differential equations. I had lost motivation at times, but people like Grant Sanderson really inspired me to see WHY I am studying mathematics. It's a really beautiful subject, and Grant just radiates zeal for it - it's great to see.

I am not saying I have the skills, but I learn the concepts the same way 3blue1brown explains It, and I wasn't teached that way. I am sure formal math education can learn a LOT from his youtube channel.

      Definitely an amazing communicator, but comparing him with someone that made profound contributions to advancing the actual field of mathematics is a bit of a stretch. Until he atleast comes up with something like a Feynman diagram, we can hold off on such a comparison.

    • @alleyway
      @alleyway 4 роки тому +1

      I’m just confused about how his idea of physical information limits in bits per unit area isn’t contradictory to his idea of infinity by simply adding a letter to a word to arbitrarily extend it. He said we have physical limits to information as an argument against simulations but then argues for abstract infinity?

    • @KristoferPettersson
      @KristoferPettersson 4 роки тому

      @@alleyway I agree it's a hole in this story, but I'm not sure it's a contradiction. 'Abstraction', if we chose to think of it as another degree of freedom (as oppose to generalization - this is arguably different) , will only have a physical meaning if we can map those freedom degrees to physical dimensions, otherwise we must work with projections which extend in time (serialization says the programmer in me). If time is infinite, then abstract infinity is a thing but at the same time the number of bits per unit will be limited because of physical constrains which limits the speed by which pieces of information can interact.

    What e^ipi captures is that the only analytic map which wraps a cartesian axis around the unit circle must have exponential growth in the radial direction. This captures a deep connection between rotation and dilation, and allows us to unify the concept of torque and linear force in the plane, into a single concept of vector. This procedure is very beautiful, and the extension of the notion of repeated multiplication is essential to the generalized operator calculus -> leading toward greater enlightenment -> I think that the notation is excellent and beloved because its mystery draws our intuitions to the important and more subtle properties of the idea of 'number'

    Thanks for sharing this video. As someone who has taught others math, chemistry, and physics, I can confirm that teaching others imprint the info very strongly with you. Having to try to relate "the book" with all is absolutes to someone who doesn't necessarily retain all of the prerequisite facts means that you have to do so much more that just repeat the info. If forces you to see things from different angles, make different analogies, adjust to different phrasings, and so much more. You often gain new insights from doing this, even if neither of you understand the problem completely.
    On a side-note, if you could ask Grant to include a link to some related problems on Khan or where ever that people can take on with the things he address in his videos, that would bring a huge improvement to the understanding of those who engage it. Without working with the tools you don't retain it well, and then the value of the video is severely diminished.

    20:12 I can't really imagine how our universe would even hold itself together and have consistency if there weren't some orderly underlying principles which dictate how it behaves. Its along the same lines of thinking when people ask the question: well if the perfect conditions for humans are so rare, why do we see them on Earth? They don't understand that they have the cause and effect switch. Cause: the conditions existed; Effect: we are here to ask the question. In other universes where this cause was not met doesn't allow the nonexistant beings there to ask the question.

    Grant has one of my favorite UA-cam channels and I’m not being hyperbolic why I say that I understand very little. But I watch again and again with hope. Best Regards Lex and thank you for everything Gilbert Strang to Grant to the one you released yesterday about self-replicating robots. I taught English for many years at PEA and only faintly remember math.
