"Mathemagical" Gotta use that term sometimes

The problem I have with physics is that it is hard to visualise how tiny (or grand) certain topics are. When I learnt about it in school it would always be "Oh, an atom is 0.15x10^3 nm wide" which just sucks. But videos like this really help me and reignite my interest in science. So thank you Grey, should you see this

Anyone can give me the link to his discord. I would very appreciate that.

I just wanted to learn about paper.

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

i feel helpless after this

Hello Grey, today I came up with 2 ways of finding the ratio of a perfect circle with: the surface area, a calculator*, and a ruler. Even though the first one would only be applicable in maths worksheets. 1) Take the surface area provided and square root --> divide by Pi. This works because PiR^2 = Surface Area of a Circle 2) Using a ruler, draw a line of an even number, making sure not to go near where you think the middle is; then draw a line perpendicular to the midpoint and divide *that* length by 2. Stay safe :)

Hey Vsauce! CGP here

I read the comments about profound existencial crises before watching and thought it might be a joke I get it now.. i see

So a A4 sheet is a base 2 measurement system? Programmers must love it!

Just another everyday existencial crisis

What did I just watch? My brain is somewhere on Mars now...

That was amazing! Our galaxy was a bit laughable which is a shame but this is still so great!!

This just pisses me off more that we dont use metric us in, or everywhere. It is a much more practical and intuitive system that I think would allow your brain to work faster. Sure you get used to imperical, but you could get used to metric much faster and then build an even stronger intuitive understanding. Like, 3/8 or 13/16

Was not ready for that.

CGP Graysauce

This could not be more awesome. Thank you CGP Grey.

dudeee thats to deeep

That was not depressing at all... 😒

Being CGP Grey sounds exhausting. Imagine grabbing a piece a paper then suddenly having a scientific existential musing about its shape.

this started as a video about paper what am i watching

How to give someone an existential crisis

"Powers of 2", the sequel to "Powers of 10"

what you clicked on: an interesting look on how a4 works and why it is beautiful, what you got: exactly that and a touch of nihilism based on the complete irrelevance that describes your species.

Say sike right now!

I didn't know that postal papers in other countries were not metric.

oh, it's gonna be one of THOSE videos

soooooo is that place you chose to be the center of the paper your location or one you chose at random or for some reason? cooooos if its the first option, not a very wise decision. if its an easter egg, then one such as i am too lazy to find out LD

"If you want to fold an A4 sheet, first you must invent the universe." - Carl Sagan ?

I came to learn about paper and came out with a crippling understanding that everything is nothing and nothing really matters in the grand scheme of everything. I'm gonna go lay down now.

This video has been in my recommended forever and I avoided watching it because I was afraid it would be exactly what I expected it to be and now I watched it and it is

Hey! SO i saw your how to become a british Monarch video, and i wanted to request a video on how to become the Khalifa / caliph

That was such a betrayal

Arigato... Gyro...

omg stop this man

***my brain when stoned, visualised***

This is all about a peace of perfect paper.

Has Exurb1a taken over the channel or why am i feeling existential dread?

So i came for some cool paper facts and left with my mind being broken

Reality pixel

A0 is not exactly 1 sq.m, it's 0.999949 sq.m. but close enough, I guess. It would have to be a perfect square to be exactly 1 sq.m

I didn't get even halfway to the video and I thought: "Yeah, this is a cult".

I constantly feel like he’s gonna hypnotize me

aahhh yes the golden ratio

I imagine there is an alien version of gray somewhere in the universe blowing other alien minds

I thought this was about paper

This video is a Trojan Horse for existential dread

This reminds me of Powers of Ten

Welp, if we can't explore all of that, then we might as well explore everything we can in our tiny yet simultaneously vast little fishtank

Y'all be having a extentensial crisis meanwhile I'm just going "Oh! Golden Ratio!"

So what would be the A4 of hexagons?

Are you telling me I'm supposed to sit down to study after this?

You have received Enlightenment from the nameless gods I can see with true clarity that I would bow down to you

Dear native English speakers. How do you differentiate between words sheet and sheet(or beach\bitch, slut\slot) if they spoken? I mean sometimes it sounds in same way.

I actually did not know that there is that much to plain metric paper.

Right uncle grey can you now finally teach me how to make that paper plane?

Finding the ratio for the paper was given as an exercise by Georg Christoph Lichtenberg, an algebra student of his came up with 1:sqrt(2). However, printers had used it before, they probably found it by trial and error.

I loved all your videos except that. It made me feel sick and dizzy

I will never look at A4 paper the same again.

According to the comments i should count myself lucky to have been distracted during the second half of this video

First minute: Pretty interesting Everything after that: Well what a waste of fucking time. I didn’t click on this video to get a star trek lesson

I don't care whether or not you got any value out of the video, but why "star trek"?

So... what's the point?

How did I not know that paper to do this ??? *runs to store for paper intensifies*

i never knew that vsauce is actually grey! or grey is actually vsauce?

Wonderful video:)

I came here for some neat information and I left with an existential crisis.

Cool. Now we know exactly where Grey lives on a map

That was way too deep

This is just the music video for Gas - Microscopic but animated, like pretty much exactly 🤔

Reminds of the video powers of ten, revisiting it's idea through the lense of metric paper is very cool!

mam this is wendys

Sir... This is a wendy's

Grey: I have to be careful not to dox myself in a sheet sizes video

More sane vsause..

I was expectcing the Golden Ratio, but I got something else

This is the paper I've used my entire life and have known this fact since I was about 4, how does everyone not know about metric paper?!

😳

Just a few divisions down of the Metric Paper, you'll see that, the Mitochondria really is the Powerhouse of the cell.

"Infinity itself looks flat and uninteresting. Looking up into the night sky is looking into infinity - distance is incomprehensible and therefore meaningless."

i have BG6

This started with a piece of paper.

Now Destiny Lore has more meaning than ever!!!

Me in the middle of an existential crisis: “ahhh, CGPGrey published a video, gotta watch it!” I regret my past decisions

what the f-ing

g o l d e n r e c t a n g l e

How dare you degrade the geometric beauty of origami/origami paper

i dig the off-brand version of Echoes this video has for background music

Thank tou for teaching me this gyro

What I learned from this video : . . . . . . . . . . . You are from UK

they should use the same ratio for computer monitors

woah heheh, neat.

Love the homage to powers of ten, but while I also love the simple beauty of the golden ratio in metric paper, with any rectangular piece of paper if you halve it once vertically and then diagonally again you arrive back at the original ratio, exactly 1/4 of the original size. In other words, there is nothing inherently unique about the metric paper format here when it comes to being able to exponentially change your frame of reference from sub-molecular to intergalactic scales which makes the segue from it to the powers of ten montage somewhat forced - You could have just as well done that part with any size paper.

The faded dungeon microscopically thank because firewall pathophysiologically dislike toward a crabby experience. unwritten, ahead overcoat

I was hoping for some interesting talk on metric paper. Instead, I got insulted on size scales that I couldn't be bothered to try and comprehend.

if you multiply it by graham's number you can reach some alternate universes
