Me: "Why does this runway have the number 8 on it?"
CGP Grey: "Iron atoms are quantumly magnetic"

[MarkRober]

The coriolis effect sneaking back was a twist I was not prepared for

[pranamd]

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.

[Tigerlady]

"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.

[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.

[PowerTrain]

he tricked me into watching a physics video after assuring me that no physics here, also now i know how magents work from quantam level

[colesrk]

As a private pilot it's a joy to see runways explained in such a fun, lighthearted way.

1. 0:13 – Small tumbleweeds ("The Trouble with Tumbles" video)
2. 0:17 – Bonnie Bee Airlines employee ("Boarding Groups Explained" video)
3. 0:23 – "-Oh, hello *again*." signifying that they met before ("The Tale of Tiffany" duology – "Someone dead ruined my life, again" video)

15. 12:07 – Zoom into the Quantum Realm ("Metric Paper" video)

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!

“There’s only math, that we’re not going to do”
As a math major, what a relatable statement

[DonPidgeon]

Me at the start: "How can it take 17 minutes to explain runway numbers?"
Me after 17 minutes: "TELL ME MORE!!!"

[garlicxi]

I like how this video went from talking about runway digits to talking about quantum physics.

[Enjay]

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 !

[timmccaughey]

"In the world of Quantum, words mean nothing." Is the most accurate colloquial take on quantum theory possible.

[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”

[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

[manslayerpupil]

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

[scylla]

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--"

[Thelongestshrimp]

“There is only math, that we’re not gonna do” is genius.

[BenTibbettsStudio]

I love everything about this: the way the script flows and alliterates and sort-of-rhymes; the way it ties into so many of Grey's other running gags; the way Grey's personality presents itself as the worst person ever to sit next to on an airplane; the ingenious move to place videos inside each other, Inception-style; and above all how well it demonstrates that no matter how hard you try to explain everything about a thing there are always more things to explain.

This isn't Grey's most important video (that would probably have to be one of the more serious topics like Humans Need Not Apply, Rules for Rulers, or Spaceship You), but it might possibly be the best.

"In quantum mechanics, words mean nothing. There is only math"

That is the best explanation of QM I have ever heard.
