We wasted so much time in school trying to figure this out. I am glad YouTube didn't exist back then - or else I would have wasted my time on something else.

I’m convinced that Euler is the most productive mathematician, nay, human in the entire goddamn cosmos. He’s so prolific it’s not even a joke to say his work in today’s era would’ve probably earned him more PhD’s then some universities have ever handed out.

I have the solution.

I paused when he said pause to try it out and spent an hour and a half doing it before pressing play again :(

Do you have to press the marker down so hard so it makes the ''RHHHHHHHHHHHHHHHHHHHHHHHHHHHH'' noise?

Yay, I figured it out myself before I continued watching. I drew a square and saw that if you start outside, you can only end outside. Then I drew a 5-sided object and saw that if you start outside you can only end inside. So if your line only has two ends there's no way your picture can have more than two uneven sided objects. I'm glad that there is no super smart way to solve it.

I know how to do it!

you sound just like the guy from numberphile...

Haha at all these people. "Technically I did solve it I just went to another dimension and crossed the corners and went on a line so this is solvable."

roses are red,

I have found a solution but the YouTube comment section is too small to contain it

lol I immediately recognize the voice's guy being from the channel Numberphile

People, please!

It's just graph theory isn't it ?

OMG you're that guy from numberphile :0

I can’t tell if the “Euler’s Trail” paper at the end was computer generated or hand drawn.
