Nice to be back : )
There will be a full director’s commentary tomorrow, but for now there’s a deleted scene to tide you over: https://www.youtube.com/watch?v=U_OXhsb6sYE
Aw no :< its members only
0:15 there is 4 runways here
It is SO nice to have you back !! ❤
Holy Crap this animation must have took a year or so😂
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.
Grey has moved beyond nesting tangents in the videos and is now nesting entire other videos with a set change. We’re dangerously close to fractal video nesting
Not MCU. This is Inception.
6:53 The Social Security number.
@TJC games And the easy to implement things are ineffective and cause suffering. It’s from the airplane video, and the hexagon video.
Also the pirates.
12:07 is the A4 paper video
This video is PURE GOLD. Thanks, Grey.
I love aviation. And I love CGP Grey videos. AND I love tangents that come back together. And I LOVE physics! I giggled like a kid through this whole video!
“In the world of Quantum, words mean nothing.” Is the most accurate colloquial take on quantum theory possible.
Yeah the sentence pretty much sums up my courses in quantum. Except we did the math 🙁
🤓
“There’s only math, that we’re not going to do”
As a math major, what a relatable statement
Can you help me with some logic proofs?
@Isky IT’s easy, just keep in mind that wires like to bite sometimes MUAHAHA!
@Ben Schmitt I am now more scared to pursue the job of an electrician
As a physics major having done the math, i’m very glad he didnt I have enough trauma 🙂
I laughed so hard at that moment. 😀
The coriolis effect sneaking back was a twist I was not prepared for
Ewoooh mark
Obviously you’re not a meteorologist, they are always prepared for the coriolis effect.
this has exactly 69 replies
Oh hi mark
Oh, Wow. This is insane. Mark actually watches CGP Grey.
Great stuff! I’m a pilot and flight instructor, so I knew a lot of this content. I even considered skipping this one because of that, but I looked at the length of the video and thought, “I have to find out where he takes this…” I am 100% glad to have watched this. I learned a lot. I had no idea Canada named runways after true north. I also knew that magnetic north moved, but I’d never bothered to learn the physics of why. I will absolutely recommend this video to my students. (Also… Winds are named backwards, but there’s an advantage to it! The runway is named the direction it goes, and wind is named from the direction it came from. Because you always want to takeoff and land with a headwind, this opposing system means the runway numbers roughly match the wind numbers. If a pilot checks the weather and knows wind is 300 degrees, then they know to land on runway 30 (or whichever runway is the closest to the wind number.) It’s great – no critical thinking required – which is exactly what you want in the busy airport environment.)
Cool essay you wrote
Wow .. thanks for that extra info!!
As a civil engineer who specifically works on airports, this video has made my day. 100% true. A lot of interesting science went on to figure out the font sizing for the runways XD
As an electrical engineer, I too was pleasantly surprised, specifically with the explanations of the electricity and magnetics portion!
I want to know about the font sizing 👁️
@B-sting.nl This, I want to know about aviation typography!
As a pilot i concur
Now I want a video on runway font science. How did we get here?
As a real world pilot, I didn’t think that what was a five minute discussion in flight school could be turned into nearly 20. Well done.
With all the jokes and tangents and cool animations I feel that extra time is well spent!
How much, if at all, does it bother you when the number is a little off?
