how hard would it have been to do 34A, 34B, 34C and so on? misaligning the numbers is super weird, i agree with you, me don't like it
phenomenal video
Wait, are we talking about magnets or airplane runways?
Grey is smart and all, but also he didnt have airplane mode on. (just a joke ofc)
This videos already has voice in spanish? this channel among others are pure gold (speaking of knowledge)
It would be nice try to put my voice over it to share this content to the world๐ณ๐
Umeona KCAA? ๐
Helm to 108 – thanks for the reference to the best movie ever!
777
I thoroughly enjoy aviation
What is the required crosswind speed when an airplane takes off from a runway?????
11:07 He went so damn deep into the video he made the cup sad.
I love how it's not simple at all.
11:04
Sad mug ๐
I just realised, there is no north star when watching the night sky rotate around the pole… or am I to believe the north star isn't actually true geographic north? ๐
I mean, I know its not exactly north and it arches a little but its not noticeable and even so, there isn't bright enough star close to the rotation center of the night sky
Magnet lore๐
they should have done i like
16LL 16LR 16CL 16CR 16RL 16RR
34LL 34LR 34CL 34CR 34RL 34RR
When you have to say โthis isnโt a physics videoโ fifteen timesโฆ Itโs a physics video. ๐
halfway through the physics video, i remembered that this started as a video about numbers on airport runways.
Being honest, I did not expect to find as complicated a topic as electron spin in this video!
I'm a physics student and OMG the physcis bit was so amazingly done.
The use of true terminology like "curl", explained in such an easy way was stunning. You perfectly described one of Maxwell's equations, the curl of a a magnetic field being proportional to the current passing through, which is in a mathematical notation ๐ปxB= mu โข J, with the triangle multiplied by B being said curl, J current density and mu the permeability of space.
It's so well done and I didn't expect such an insight into such a complex yet beautiful physics topic in a video about airport runaways
Keep it up friend!
this is why there's so much maths in engineering, all of this just to number a runway.
5:45
Out of those million indicators, in modern aircraft anyway, is a navigation screen that displays your compass heading, usually on the aircraft symbol or one of the top corners, which the pilots rely on anyway as it shows them the route they have to follow on the flightplan they've set. If the autopilot is engaged you can set the heading manually and watch the aircraft's direction of travel change with the heading you've set.
Also, the pilots will be thoroughly familiar with every switch, every display and every feature of the aircraft they're flying. How do you think they start it up from cold and dark?
As always, a pleasure watching you de-confusing confusion.
Grid, True and Magnetic North, so glad I live where the declination is <1ยฐ much less of a pain
Video: The โSIMPLEโ secret of runway digits
Me: ๐ตโ๐ซ
16:56 she is SO HAPPY and i love her for that ๐๐๐
It's just a shorthand for the runway's heading.
Saved y'all 17 minutes.
Wow
other way 'round 2:48 I looked up videos of those kinds of winds in the northern and southern hemispheres
Grey had too much coffee this morning
Im glad this wasn't a physics video
You canโt beat Physics, itโs everywhere.
I really like your metric paper zooming ๐
How did we go from runways to the inside of earth?
The only CGP grey video i don't understand
This is definitely NOT not a physics video!
15:20 "After the Flip". Priceless.
That was a fantastic video. Thank you. Wasn't expecting that.
All along, I thought those numbers on the runway were lucky numbers….
Grey please stop flirting with… the universe itself(?)
The simple, i-need-17-minutes-to-explain-this, secret of runway digits.
Hah! Nice fifth element reference.
truly a moment
*"HELM, 108!!!"*
"…Helm to 108."
8:19 he is painting so fast !!!
i love how the stick figure gets so confused about how you just appeared there. 0:23
Who else noticed the kurzgesagt posters in the background at 11:49
I hate this video because itโs better than anything Iโll ever make lol
3:41 "Why are we made to suffer?" Oh poor Grey…
