  • @TomLumPerson
    Me: "Why does this runway have the number 8 on it?"
    CGP Grey: "Iron atoms are quantumly magnetic"
  • @Syy
    Grey has finally reached Phase 3 of his Cinematic Universe, where every video is constantly crossing over and cameoing with each other, and it is incredible.
  • @Tigerlady248
    "That we're NOT going to do" just gives the energy of Grey trying to understand this for 100 hours and throwing his hands up in a 'screw, it doesn't matter, I DON'T NEED TO KNOW' and I love it.
  • @pranamd1
    Every time Grey said "We're not going to talk about physics", I got more and more excited, knowing he was foreshadowing all the glorious physics to come.
  • @MarkRober
    The coriolis effect sneaking back was a twist I was not prepared for
  • "In the world of Quantum, words mean nothing." Is the most accurate colloquial take on quantum theory possible.
  • @colesrk
    As a private pilot it's a joy to see runways explained in such a fun, lighthearted way.
  • @garlicxi
    I like how this video went from talking about runway digits to talking about quantum physics.
  • @DonPidgeon
    Me at the start: "How can it take 17 minutes to explain runway numbers?"
    Me after 17 minutes: "TELL ME MORE!!!"
  • @SoniasWay
    “There’s only math, that we’re not going to do”
    As a math major, what a relatable statement
  • @Sol_VI
    I just love how the video implies that Grey just randomly starts making a runway video and the guy sat next to him just has to deal with it the whole time
  • @Enjay80
    Small correction:

    Canada uses the magnetic numbering system for the runways as well, except for runways north of a specific parallel, when the true north and magnetic north diverge too much. So for your travels where 99% of people live in Canada, it makes no difference for pilots !
  • @cru_bii
    by saying that it's completely normal for him not to upload for a hundred thousand years, grey's confirming he's STILL SET on becoming immortal
  • @scylla1772
    I can just picture Grey typing up the script, mumbling to himself with increasing fervor that "this isn't a physics video. This isn't a physics video. This ISN'T--"

    P.S.: If you say something about the Airport Codes video, don't. This was released before that video came out so unless it's foreshadowing, you're INVALID!
  • I love when Grey has videos about him going off on tangents to random strangers, that person is looking for an escape. As if in reality, any one of us lucky enough to be in that situation would be hanging on his every word
  • @JHarris
    Hahaha, as a pilot my initial thought before watching :
    “It doesn’t take 17 minutes to explain runway numbers”

    After watching:
    “So thorough, fantastic as always CGP Grey”
  • "In quantum mechanics, words mean nothing. There is only math"

    That is the best explanation of QM I have ever heard.
  • @Thelongestshrimp
    “There is only math, that we’re not gonna do” is genius.
