#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.

@@ryPish well of course if you try to apply it in general terms you'll find that it's not always true.

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.

for someone who has been struggling with maths since I was a kid. I force myself to learn calculus In univesity. The only way I could understand It Is by understanding the concept by their roots. The only place where I found the same way of understanding math is on 3blue1brown YT channel. 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.

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.

Grant Sanderson is an understated genius. 3Blue1Brown is the type of channel that can ACTUALLY change the world - One mind at a time. He makes understanding the world around us interesting, while also making higher Maths accessible. Such a refreshing change from the usual distractions.

I really believe Grant is the smartest person I've heard speak. Not just because he understands a whole lot, but because he is able to communicate it. I see him as Feynman's successor in that regard. What a champion!

@shawnington

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. He definitely makes Neil Degrass Tyson look quite silly though!

Mr Sanderson has a clarity with abstractions which makes you feel like he can wield them like swords respectfully sharpened beyond peacetime demonstration. You simply can't help giving him a lot of respect out of pure self-preservation.

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

@@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.

I'm blown away: I just googled "Grant Sanderson" and he is the guy behind 3Blue1Brown! One of the most cogent and explanatory KZread channels I've come across!

Thank you Lex for putting these interviews together, putting yourself out there, and having damn good conversations with risky questions. Really appreciate you, friend. Cheers

Love 3blue1brown have this guy back on! Need more podcasts getting “into the weeds” with math in a conversational manner. Awesome job!

These are just unbelievably amazing interviews. You are so right when you say "never too philosophical."

I can't explain.....It gives me immense pleasure to see two of you talking deep things, discussing things that I have interest in too. Two blessed souls.

I loved his Essence of Linear Algebra series

Thank you so much for having Grant on the podcast. Fascinating young man!

This is such a beautiful conversation. The brutal honesty of Grant's "I don't know, man!", the 'aha'-moments, the way the both of you can compress years of discussions I've had with friends in to one-liners and then build upon them further... This just keeps giving! Thanks so much for this

This was (at least for me) hands down, the best interview I`ve experienced. 2 people with minds set in two different fields yet still relevant to each other. Many of the things Grant says really is mind opening. Grant making great claims about questions about infinity and Lex showing great responses "some push backs too" to those. You both are great and I loved listening to this.

Wow! While I could not grasp some of the more technical mathematical concepts discussed, I still enjoyed how clearly Grant can think and express himself. It's clear how his deep learning playlist is so beautifully explained

1:01:14 Such a great ending note on how Grant Sanderson helped showcase the creative side of mathematics.

Thank you so much, Lex, for gifting such a beautiful podcast with such a superb personality. God bless you.

Grant's description of the process of understanding is gold. Starting from definitions is like providing students a list of places to visit with no map to put them on. Providing visuals (or other concretizing examples) early on provides a structure that later knowledge can adhere to

I’m absolutely head over heels that I found this channel in 2020! It’s everything I wanted from rogan with no filler and less entertainment based guests. I love rogan too. But we needed this! Lex proves not all heroes wear capes!

This guy is my favorite guest on this podcast so far.

Always watching his videos with his voice and manim, and also his pandemic videos about maths, and then this feels so different now, having him speak to someone else and seeing how much enthusiasm he has for all these things!

Thank you, Grant, you've turned on so many lights I didn't know were off. Keep up the good work! And you too, Lex, you're doing something important with these interviews.

Wow, wow, wow, My wish has been granted!! I was eagerly waiting for this one!!

Grant's visualisation of mathematical concepts becomes the heart and soul of insights!

This was one of your best interviews yet on this channel. You really have a gift for asking thoughtful questions that guide your guests toward insightful discussions. Keep up the great work.

Thank you very much for this Interview. 3Blue1Brown is my one of my 2 favorite Math series on KZread. Additionally it is the best mathematic show. Extremely helpful. You are doing great work Lex. Lex and JRE are hands down the best podcast on KZread.

Grant Sanderson's eloquence is simply amazing. Concepts , Ideas and Visualisation seem to get converted into almost musical articulation with effortless ease in his brain. The cascade of words, phrases and sentences that gush forth from his mouth as he conveys his Mathematical understanding in English language simply enthralls me! I have never seen him fumble for a single word, ever !!!! Thank you Grant . Keep going.

Wow, Grant's mind is sharp as it can get. Amazing to see him articulating complex responses while talking around the subject. Listening to the podcast is great. Watching it is another level. Thanks Lex!

This channel is officially my favourite. Keep it up Lex!

Oh, I think now I have some intuition about what infinity is. I could listen to these two infinitely! Good job, Lex, as always!

I have watched many of your videos, and just discovered these with Grant... I decided I'm going to jump back into math for data analysis and revisited 3blue1brown recently. Thankfully, the YT algorithm gods gave me these video suggestions of yours. Lex, I really can't tell you how grateful I am to have found your podcast. When I'm too exhausted to work late or study, I can cook/clean/etc. and still listen to such high quality, intelligent and entertaining conversations knowing that my mental reserves are spent in a productive and stimulating way. I appreciate you and your work very much.

That was the most beautiful way to end a discussion. Bravo!

The best thing about Lex is that he never pretends that he completely understands, and he never pretends that his questions are naive. He prepares beforehand and is so honest about what he knows and what he wants to know during these interviews. Like "Are you ok with the existence of infinity" is a great question. He asks the questions that stem students, like me lol, don't really get to ask or don't know how to ask.

Lex, I've listened to so many of your more recent interviews, and just today learned that you've interviewed Grant Sanderson multiple times. I had to check it out! The man is a legend in my mind, and I sooo enjoyed hearing more of his thoughts, beyond just what shows up in his videos. This was great. Thank you!

I can't describe the joy I get from Grant's arguments. He sees the essance of everything he talks about, as if he programmed the universe

thank you for this amazing conversation. really enjoyable and thought-provoking like all of your videos

Grant and lex conversation about abstraction from visualisation to the concept of infinity and the very essence of science is the highlight of this video. So succinct and apt to use the abstraction as processed by an AI to human concepts. Love your work Lex and Grant. Keep up the good work.

What an awesome episode. Keep the great guests coming!

So weird looking at Grant's face having never seen it - like meeting a vendor that you've only ever talked to on the phone! Great chat!

Was just thinking about how great it would be to have him on your podcast. You are two of the most impressive channels out there, thank you both for doing this interview!

Great questions, great answers by Grant and really I liked your revision of his answers.

I have been waiting for this since you put up the Twitter post in November! Thank you!

This was one of the best interview I've ever listened to Fantastic Job both!

From Lex's facial expression, I'm pretty sure he is trying really hard to catch up with Grant's thoughts and come up with meaningful questions that can move the conversation forward at the same time. This is probably one of the most challenging podcast for him. It requires a lot more than common sense, or general knowledge of math, this requires deep and critical thinking of fundamentals in math. But Lex is already doing a great job, I can't fathom a better host.

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.

27:00 definition of abstraction… brilliant❤

Being able to participate in a conversation with two such amazing and super enthusiastic individuals would surely be a defining point in my life

Wow, Grant's comment at 35:11 is amazing. I too get bogged down and confused and bored when the theory is presented first... but his methods of showing examples first and then tying it together with theory is amazing. Now I know why his videos are so good at explaining things so much better than the average lecturer...

Seriously one of the absolute best videos ever made, I wish I could broadcast it to everyone! At least it's here, to be found, whatever that "means".

You are more than I can't thank you enough. Thanks.

This guys videos on neural networks and blockchains are the best on youtube. Grant should start his own teaching platform.

Thank you for this high grade conversation! Very nice.

Grant Sanderson, One of the people I'll always be grateful until the last day I breathe!

31:17 love the discussion on accepting that you can't concretely understand very abstract concepts in a way that you can anchor your understanding simply. Kind of makes me think that is why these concepts are intrinsically abstract. :)

Amazing guest and content - I will suggest it again : get Jim Simmons on the podcast to talk math ! (billionaire mathematician founder of Renaissance Capital)

I could listen to Grant all day. Good voice, smart thoughts.

The specificity of your guest is wonderful to hear. Your guest is quite a brilliant speaker! He reminds me of no other than Ed Witten!

Great job done by the host. Impressive insight shown by Grant about basic questions with complex answers, given they exist at all. But, much improvement can be made by the host with regard to articulation and conciseness.

I love both of you for each and every word of this!

I just got into the Lex Fridman podcast a couple months ago, and today I thought, 'Oh man, Lex HAS to interview Grant!'... Imagine my surprise when I found that the conversation already exists! Now to enjoy some Lex + Grant goodness.

This is a superb interview! It's interesting from the start to the finish.

Been waiting for this all day...

You're f'ing awesome man, thank you for the work you do, keep it up🙏

You are doing a great service by interviewing such wonderful people. While a lot of the people here are focused on abstract ideas, it will be useful to also interview people who do hands on work like artists, engineers, architects, product development teams to understand their thought process and creativity. Like for example, how on earth anyone was able to come up with an idea a bicycle, a microwave, risk insurance. I believe understanding these kinds of traits are important to make progress towards Artificial General Intelligence.
