Chyrosran22 : This just looks like molecules to me xD . Ethane, acetaldehyde, isobutane...

TooJ Kool : He has an unsolved Rubic's cube. I don't trust him.

Hantaa : I seems like anyone who was taught about basic organic chemistry could solve this.

Olivor Holman : Those trees brought back horrific memories of organic chemistry...

Script Kiddie : It's not your fault

ViralCarelessness : is it just me or does this dude give off an aura of being a total badass?

gp5 : This guy's accent makes me think he's about to say "Do I make you horny baby?! Do I?? Yeaaaaaah"

NoriMori : "Like all mathematicians, he's tall, blonde, and handsome. Yeah? …YEAH?" Oh James. XD Besides, you're a ginger! XD

Jack Middleton : Like most mathematics and scholastical problems, the hardest part is understanding the pseudo intellectual peacock question phrasing handed out by the bureaucratic hierarchy of the same variety.

hybby : Matt Damon = Math Damon?

chomage : It looks like drawing isomers of molecules.

satyrkrieg : Wouldn't the real difficult problem actually be to prove that there are only 10 trees and no more with that characteristics?

londontrada : This is Brian Cox's secret ginger younger brother. Hidden from the people, maligned by the press. He lives in a basement in Northampton and Brian bullies him for his ideas, steals them and then passes the ideas off as his own. The question is, how can we think of ourselves as decent human beings when we allow this kind of thing to go on in our own country. Mad or genius? You decide.

NAp51 : A chemist at heart, I immediately associate mathematical trees with structures of alkanes. is there any real connection?

xelarutra : Is there any way to turn off that marker sound?

Mike MMA : There are, on average, 183 sesame seeds on every Big Mac bun from McDonald's. I counted.

henriok : When I went to university and got an assignment like this, it either assumed or expressed that you should both show the solutions and prove why there isn't any other solution. So, even if it takes less than 2 years to find 10 solutions, it might take a bit longer to prove that there isn't any more solutions. In this case, that might be easy as well, but I don't think you stressed this point that finding solutions that satisfies the problem doesn't really solve the complete problem.

AhoraLoVes : How do you prove there are exactly ten solutions?

manualLaborer : is that a tattoo on your hand? maybe a tear? indicating you've killed someone with your lethal mad math skillz?

fredguy2 : dude must be laying pipe on the regular.

Helium Road : So how much money did it cost nd how many people died saving Matt Damon in that movie?

NOTWorthless : The "urban legend" is not a legend. This is roughly what happened to George Dantzig, who is famous for his contributions to linear programming among other things. Snopes has a page on it.

antiprotons : OMG!   I wish I had him for my math teacher when I was young. I was totally at a loss until I found a book with calculus in it...    Calculus was what really got me into math (calculus is more fun than other math  :) Nice video!

Jack Burns : This wasn't the problem that took MIT professors 2 years to solve in the movie. This was the problem: 1) Find the adjacency matrix A of the graph G 2) Find the matrix giving the number of 3 step walks in G 3) Find the generating function for walks from point i to j 4) Find the generating function for walks from points 1 to 3 Don't know if anybody can do it at home or not.... I know i can't. As for the tree problem the movie never mentions if it was difficult or not.

Michael Hart : that ended rather abrubtly

David Andrews : From an American point of view, the take home message in the movie is that there are in our country brilliant people who never get a shot. I knew one. Unfortunately, he fell under a bus and was killed on his way to his job on the nightshift. The odds are--I will never meet another person as gifted.

Green Geralt : That unsolved Rubik's cube pisses me off.

Philgob : This is not hard hahaha... The hard part is proving the maximum number of trees, which is what the "mit professors" do in the movie. What you did barely even has a mathematical aspect to it... It's just a series of random trial and error drawings

Five Sigma : Yeah but was it numberwang?

Chris Kavanagh : What the heck is that machine directly behind you on the table (around 2:06)? Is that an Enigma Machine, for Christ's sake, lol?

The Hammie Matt : what about the Math in Interstellar?

sjbrooksy45 : Finish the f-ing story! What happened?

Tom Tom : Maths in movies are always ridiculous. They love to have sigmas (sum) on blackboards and some integrals but most math in movies are either meaningless or terribly easy .

themangiant : He didn't say that it took 2 years to draw them, but that it took 2 years to prove. I'm not a mathematician but I took that to mean that it took them 2 years to prove that those are the only possible trees with those parameters.

casperado666 : these guys are so british, they shit the queen

Ziggy Stardust : 2 years for this problem? I found them all in less than 20 minutes.

holycow343 : this reminds me of organic chemistry

PMRstudios1 : "some of the words are greek." then says latin words....

Ray Flores : Nice. But the problem is not quite "finished". How can you be so sure there is no other trees? Just because you can't find it, it doesn't mean the 11'th tree doesn't exist.

John Horak : reminds me of drawing isomers in orgo 

sea monsta : Do you like apples?

medved : Of course any real problem would demand to produce something more general for trees of size N, or at least prove how many variants there will be.

El Baron Samedi : I guess the difficulty is on prove that there are 10 forms for n=10 ¿?

Delivery god Yato, at your service! : That's exactly how college is though. You learn so little you come out dumber sitting in lectures all day than the people reading in the library.

Leonie V : The pigeon wallpaper is arguably the best part of this video  :D

VGM_ : From the title I thought it was talking about hunting for discount clothes and stuff at Goodwill the store

Monster Coinz : It's always easy once you know the answer. It took hundreds of years just to design a working lightbulb. We all know how they work now.

Alan : Math is so easy... People(The one's who DON'T have learning disabilities) just don't try.

Sudev Sen : the problem coudnt have simply been draw 10 things that's just tail and error

varigdc10 : With the advent of the Internet and all current technologies the first time I was introduced to the term " Google " a bell rang inside my head. I knew I heard this strange word somewhere a long time ago. I went to sleep that day thinking about it. The next day, bam!, I remembered. In 1964 I was a sophomore in High School ( Lane Tech, Chicago, Illinois ) my Calculus teacher asked if any of us knew what a "googleplex" was, nobody even heard the word. He went on to say it is a number, integer, with an infinite number of zeroes after it. The whole thing made sense in no time, today's Internet Google is exactly this, infinite number of information as I first heard from my teacher in 1964, wonder what he would think if he was alive today. Math is wonderful, and I hated it all during school, but had to do it towards BS EE.
