Hey, I thought this video was about nails and puzzles !
But you taught me interesting math stuff, though I'm not really into math.
You nailed me. I'm puzzled.

[PeterJavi]

"Oh, a cool carpentry trick."

"Wtf, holy shit. Unexpected beautiful mathematical theories."

YouTube recommendations gone right.

[justsomeguywithsomemustard]

Jesus talking about nails, string, and math.. gonna subscribe

[dramawind]

I really hope this channel blows up like 3Blue1Brown or Numberphile. This is some top quality content.

[GoldPlatedGoof]

Hey everyone,

A lot of people felt that the thumbnail was not reflective of the content of this video so I decided to change it. I am truly sorry to anyone that I may have annoyed. The change may take a few days to spread to all places on YouTube where this video appears.

While I certainly want people to watch my videos I would never intentionally trick anyone into doing it. I want people to have a good time with my channel and my content and I hope you believe me when I say that I had no intention of being misleading.

If you just want to see me pull the nail in the thumbnail you can skip to 14:30.

I wish you were my math teacher in high school, I probably would have found it more interesting and relevant, and would not dislike it today!
You explain things well and Your enthusiasm for the subject is contagious!
Super rare in math teachers (in my experience at least!)
Thanks! I'm so glad I stumbled upon your channel!!

So I wrapped the string around my nails and my fingertips turned blue. How do I express this mathematically?

[earthbjornnahkaimurrao]

I finally understand string theory! : )

[cArLaEzXy]

Your passion for mathematics is inspiring my friend. You will never know how badly I needed this. Fantastic video and true appreciation for your work!!

[hundertzwoelf]

Nice analogy with the Rubik's Cube. Actually, in cubing we also call move sequences which follow the form ABA'B' a commutator (the ' indicates the inversion). They're typically denoted with [A, B], just as in mathematics afaik.

Keep on doing those great videos, really love that stuff!

[GibusWearingMann]

I have to go out now, but when I get back home I'll definitely subtitle your video. I enjoy your content, and I'm that rare breed of person who enjoys subtitling work.

[Quiscalus]

Wow, I was 100% engaged for an entire 15 min video. Don't remember the last time that happened. You're really good at breaking down and explaining concepts. You're a natural teacher. :)

[EtotheiPi]

Not only great content, but also outstanding explaining. Not an easy task in mathematics!

[miksurankaviita]

This is like the best introduction video to group theory!! Keep it up!

[davidmurphy]

Excellent, clear explanation with tonnes of contagious enthusiasm. You lost me on two occasions but that's ok, it's good to be challenged and I'll give it another watch at some point. Delighted to sub.

[KeyboardNewbie]

Omg thank you so much for doing this. I'm a math undergrad who is trying to learn about all the different fields of math and this really helps me see a bit of the bigger picture that's out there. Please keep up the good work, the amazing explanations, and over all keep adding the subjects that cover the topics that you mention throughout the video, that was my favorite part of it

[samueljimenez]

Agree...this channel deserves to blow up. Sir you have the secret sauce to make math interesting.

[invinciblemode]

Came for the maths, stayed for the luscious locks

[emilsvahn]

I Love your videos dude! You're amazing

[mrwonderwaffles]

This channel deserves to be as big as 3Blue1Brown
