Vsauce as a toddler: O... O...
Vsauce’s mom: He’s saying his first words...
Vsauce: Or am I?

Seeing Michael on the square wheeled tricycle brought great joy to me

[avidcloud]

vsauce: today we are going to talk about the brachinstochrone.
vsauce about 2 minutes later: and 7.5 billion people wouldn't even fill up the grand canyon.

I'm studying physics for university entrance exams, and I casually re watched this video only remembering the brachistocrone curve, and when I saw that I just realized that this is Snell's law right before he said it
I'm f*king proud of myself right now

The speed at which Adam figures out how he wants to build shit, is amazing.

“Do you have a polygon around here?” Is the most Vsauce this I’ve ever heard

You know a video is good when it gets 2.5 million views with a title "The Brachistochrone" and a curve as a thumbnail #NoClickbait

Michael: “Adam and I are going on tour; we hope to see you there”

Me: *super excited*

Also me: *realises I’m 5 years too late*

[PaulGaither]

Vsauce: Do you have a favorite polygon?
CGP Grey: Hexagons are the bestagons.

Michael and Adam working together is the perfect example of "the scientist comes up with an idea and the engineer makes it work"

[VeritasGames]

23:39 Please don't look at me like that Michael.

0:41 It was an absolute pleasure to be featured in one of your videos, Michael! Thanks for showing me in the video.

Vsauce wedding:

Do you, Vsauce, Michael Here, take this woman to be your lawfully wedded wife?
"I do."
"Or do I?"

"If every single one of us held hands in a chain of unity around earth." A lot of us would drown.

[yeahboi]

23:45 I love Michael having the idea to just stare at the camera instead of looking at his dream come true

[Gwynstborn]

How did Adam manage to bald so gracefully. Also when 2 exceptional people get together it's always a treat

[Amongst_Shadows]

9:05 is so wholesome
“I got some protractors there”
“Oh oooh”
“You’ve got a compass extension”
“I’ve got all sorts of things”
“I feel so guilty this is a dream of mine come true”

[generator]

"Do you have a favorite polygon" is the nerdiest thing ever said on this planet and I love it

Personally I like apeirogons

[colinsheehan]

Adam: “I’ve got some protractors here.”

Michael: “oooo”

At 23:39 Michael isn't watching the experiment, but rather he's staring at us🙂
