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

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

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!

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

hybby : Matt Damon = Math Damon?

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.

chomage : It looks like drawing isomers of molecules.

Script Kiddie : It's not your fault

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

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

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

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.

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

The Hammie Matt : what about the Math in Interstellar?

Michael Hart : that ended rather abrubtly

fredguy2 : dude must be laying pipe on the regular.

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

holycow343 : this reminds me of organic chemistry

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

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

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

Alan Jay : "This is a problem we can all do at home. I promise" Yeah, right!

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

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

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.

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

DanClarky1 : Yeah but was it numberwang?

Hanan Nasser : Reminds me of stereoisomers from organic chemistry.

John Horak : reminds me of drawing isomers in orgo 

Full On Biscuits : I just passed geometry and going on into 11th grade.....I HAVE NO IDEA WHAT ANYONE IS TALKING ABOUT!!!!!!!!!!!!!!!!!!

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

Immortalマリオ : They look like network topologies

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

MV Bros. : there is one thing that i think he may have overlooked. He tells us that he believes it is relitively easy and it wouldnt take MIT professers 2 years. while i agree with this statement, there is one part of this problem that is particually hard. He tells us the rules and then imediatly tells us there are 10 trees. MIT professers working this problem (assuming that this really happened) wouldnt have known that. They may have spent the first week figuring those ten out, and then spend the remaining 103 weeks looking for more answers and not relizing there wernt any more.

SmileyMPV : Fun fact: Only for n=3 there exist no irreducible trees.

Vitor Vilasanchez : "and that's a guy with a funky afro" best quote EVER!

Nicolas Zunker : i feel like this branch of mathematics (if youll pardon the pun) comes up a lot in organic chemistry, would i be right in that assumption- and what is it called?

Josh Denham : Lol you look just like my son

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.

Jasmadi Syah : Yes this is easy, and its funny how hard for you guys to realize this is not the correct problem that took MIT lecturers 2 years to solve. This is the later one.

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.

Jose Guevarra : Prove that you drew ALL OF THEM!

David Winsemius : Cute. But the American student came late to a regular day's class (not an exam) and thought it was a homework problem. His name was George Dantzig and the professor was Jerzy Neyman. The paper was accepted in 'The Annals of Mathematical Statistics'.

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

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

Sergio Díaz Nila : I think they just went for something easy to do for Matt Damon.

Hector 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.

D Kahn : The best kind of Professor, is the kind that is looking for students smarter than them, and wants to learn from them.

Christopher Sewell : When Dr. Grime describes the first type of banned transformation, he is actually showing something called graph isomorphism. Two graphs are isomorphic if there exists a mapping from the vertices of one graph to another which preserves the edges between them. Now before you really understand a homeomorphism, I believe it is first necessary to understand the concept of an elementary subdivision. Note how Dr. Grime goes from the first graph to the second banned graph by deleting the middle edge and replacing it with a vertex and two edges to reconnect the graph. This process is called an elementary subdivision. Finally, we say two graphs are homeomorphic if they can both be obtained by elementary subdivisions of some other graph. For a more complete introduction to graphs and trees check out "Discrete and Combinatorial Mathematics" by Grimaldi. In all honesty, you could begin reading this book with a basic understanding of high school mathematics.

sea monsta : Do you like apples?
