"So there was this conspiracy guy next to me on the flight talking about how everything is connected, runway numbers, the flipping of the north pole and quantum physics. It was crazy, man!"

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.

Phenomenal video. The fact that there are so many references to previous videos is more than just a gimmick, or a fun easter egg. It helps emphasize the overall theme of this video, which is that _everything is connected._

Regarding the leading zero: It should definitely be there, for clarity. If you hear "ZERO SIX" you KNOW without a doubt that it's runway 6. If you only hear "SIX" you COULD have missed a leading "TWO", so there's a potential that you think it's runway 6, when it's actually runway 26. If you expect two digits at all times, it may avoid confusion. Under this system, receiving only one digit should cause you, as a pilot, to verify the missing leading digit. Omitting the leading zero causes you to happily accept a faulty one digit runway number.

QM is confusing and sometimes counterintuitive because many of its features don't have macro-scale parallels to provide intuition like we can gain from everyday-life physical systems. However, many of its features do have those parallels, and despite fundamental limits on the observability of entire pictures at once, the vast history of incredibly successful QM experiments makes it possible for one to form a working picture and sort things into "confidently physical" and "purely theoretical/mathematical" descriptions. It just takes... years, and of course never really ends. But you can do it if you so desire! Best of luck.

@TIMEBUCKS™ Hi

Also many modern ships use gyroscopes as compasses, where due to precession, when applied with a slight force (damping) a gyroscope's rotational axis will align with that of Earth as a stable equilibrium. This mechanical device, as long as kept spinning, tells you your compass bearing in relation to geographic (true) North, and also your latitude without any need for a sextant, and noting which direction it spins, it also tells you which hemisphere you're on (if the stars won't). It still won't tell your latitude, but John Harrison's H4 will.

Planes are similar, though the traditional magnetic compass remains for redundancy.

He went from an aviation video to geography to physics

Just want to note, as a Canadian pilot, the True North runways are only in the northern territories, where compasses are too unreliable to be used. The southern, bigger airports all still use Magnetic North for their numbers. You can tell if the runway uses True North since it will have a "T" after the number. I also haven't heard of trying to get more countries on board with true north? I'm not sure if that's a thing.

This is probably one of my favorite videos youve ever done!!! I did not sign up for over half of what I got when clicking on the video, but got everything I signed up for! Brilliant and so much fun! Love learning from you!

I hope the whole team of people who work on these videos are really proud of this video. The quality of design and animation present here is seriously pushing the bar of quality for not only educational and informational videos on KZread but in general. Seriously, this is something I wish I grew up with, it's insane how nice it can be to learn about these niche subjects, even if there's nuance left on the cutting room floor for the sake of time.

I'm a pilot from Canada, and Transport Canada absolutely LOVES throwing magnetic/true heading questions on their exams, usually not even related to the skill the question is testing. Ie: suppose you want to maintain track 170 in Northern Domestic Airspace with a TAS of 150 knots and the wind is at at 110 degrees and 40 knots, what heading should you fly to maintain track? If you do the calculation right but choose the answer given in degrees magnetic from the multiple choice you'll fail the question since all headings in Northern Domestic Airspace are given in degrees True. Pure, unfiltered Canadian-style pedantry. It's only applicable in Northern Domestic Airspace (anywhere north of Yellowknife and Iqaluit basically) which 99% of Canadians have never and will never go to, but damn it, they will make sure you learn it for the exam!

Hey! Just one small detail: Canada actually uses magnetic north to number most of the the country's runways. In an area called "southern domestic airspace". However, in the creatively named: "northern domestic airspace", true north is used for a number of reasons. Particularly navigational errors that happen at high latitudes, like magnetic dip and northerly turning error. Great video btw.

I’m a student pilot, I was already kind of past this point when I watched this video, but it absolutely reinforced my understanding of runway headings

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.)
