Finite Simple Group (of Order Two)

[Rywen]

The only thing I don't understand is the hand gesture he makes when he says tensor.

[juncode]

guys you just rock

[sammyjny]

this song is so finite but i can listen to it infinitely :)

[Liebetraurig]

23 people lost generality

[V22293888]

well... its a simple group right... so one of the elements is e and other.. lets say a.

well a has to be its inverse for this to be a group, i.e. a^2 =e

i mean... then statements like 'you complete me' do not really hold because for that two distinct elements a and b should exist such that a*b = e where a!=b.

but for order 2 group we know that a=a^-1

i think the song would have been more romantic if the group was of order 3.

[Divingraven]

I actually love the little 'QED' square he makes with his hands at the end much, much more than the sincerely overused heart shape. It's a neat ending.

[Gadspy]

I can pick out math puns, but the real problem is that I can't be sure anything I don't recognize as a math term isn't actually one.

[NWRIBronco6]

@Gadspy

In this song - it is.

[schistef]

can anybody lyric their song?

[skyhorizon523]

this is absolute hilarious and awesome, great job guys!

[dinobotpwnz]

You don't need to know tons of math to "understand" the song. It's a love song, anybody can see that. You just need to know a lot of math if you want to undertake the pointless task of defining every word that they use. The song doesn't magically take on a whole new meaning to someone who knows what a "forgetful functor" is. The math words there just jazz it up. But unlike most songs that talk about math, the words they use to jazz it up actually refer to research level ideas.

[sameerpatel105]

which university is this at? lol

[sammyjny]

this is fucking classic! notice the professors in the back :)

[insert1penguin]

wow i didnt understand any of that

[epb2102]

the fact that there aren't 100 million views is an indictment of America.

[Twidgett02]

@epb2102 'Cause only America can view the internet... Right?

[SerbAtheist]

She seems like the neutral element in this finite simple group of order 2.

[sammyjny]

man this is too good

[webmastertool]

I'm 12 and i know exactly what this is.

[munizrfelipe]

@webmastertool Like anyone care. outta internets kid

[OxymoronicRomantic]

I think I just fell in love a bit.

[karlkkendall]

oh my goodness!!! this song is way to good to be true!!!!!!!!

[san2chi]

Kudos to who wrote the song!

[rickylain]

singing is awesome. but am i the only one that find it not funny.

[xblademasterx416]

@rickylain I dont think that it's funny. But people laughed because of the clever lyrics, and boy do a find them clever! (at least the ones that I understand)

[semperFi4ever100]

@qwertypluss Dang! They write a song that is about as funny as you can get with group theory, make it intelligent and perform it pretty well at campus, put the whole thing on YouTube and the first thing which comes to your mind is how ugly they are? Sorry, but that's low...

[qwertypluss]

@semperFi4ever100 They're all beautiful :)

[semperFi4ever100]

@qwertypluss You bet your ass they are. Nerds FTW!^^Speaking as one

[yorky115]

this is just some quirky love song with the odd mathematical reference used as a descriptive word.

why are people making out that this requires some-kind of galactic intellect just to get a basic understanding of this rather naive , tasteless tripe????

[prgm001]

@yorky115 You clearly don't know very much maths then! Almost every lyric contains at least one mathematical reference. It doesn't require a strong intellect though, just a good knowledge of maths.

[mikehadid]

i so badly wanna chill with these guys

[awestruckgeek]

AWESOMESAUCE!

my joy is without upper bound:)

[TheAgy777]

lyrics&explanation please

[BombadilcommaTom]

@TheAgy777 You're going to need a powerful majority of the wikipedia portal on mathematics to explain everything in this song. It might be better to just get a B.S. in mathematics. It would be faster.

[Wizkid717007]

@BombadilcommaTom lol @ powerful majority!

[ams2990]

@BombadilcommaTom Reading analysis-related pages on Wikipedia is super painful. I'll stick with Rudin, thanks.

[markusbirth]

@BombadilcommaTom Just watch "The Big Bang Theory"… ;-)

[rozza2058]

@BombadilcommaTom I'm 3 and a half years through a 4 year MMath degree and I don't get most of this, though I am currently working on classifying simple groups, so I love this song!

[Rywen]

@rozza2058

I hope you're kidding or MMath doesn't mean Masters like I think it does because I'm 3 semesters into Math degree and I understand most of this.

[rozza2058]

@Rywen No, dead serious, but then I took a lot of modules in computer science.

[TheAgy777]

i cant understand the expertise

[rlinfinity]

@TheAgy777 I wrote a most wonderful line-by-line list of topics referenced, but this Youtube comment is too small to contain it

[TheAgy777]

@rlinfinity lol then please message me!

[rlinfinity]

@TheAgy777 :) Message me your email address. I don't know how to message on Youtube anymore. they changed too many things!!!

[riddleman65]

Awful

[CaninAble]

That was/is so great in so many ways. Thanks, guys!

[TFI2010gmail]

They really have romantic relationships covered. In the Vitali sense.

[jayanthyk]

Thumbs up if you saw the ghost sitting up the stairs?  :D

[arynaq]

Where is the remix?

[tahkevin]

Reminds me of linear algebra :)

[asprinal]

Damn! Serious props from this Topologist for working in the Axiom of Choice!!!

[I3L4NK]

Quod Erat Demonstrandum, indeed!

[StringUsername]

Please marry me.

[suzushirou]

I wish I was smart enough to understand this...

[NicolaRuth88]

i love klein four, an ex even wrote to them and they made me a video, its on here "A solid for a fan"

[drmathman]

Inspired partly by the Klein Four - and largely by Tom Lehrer - I wrote and recorded "Derivative Rag". Please check out the video that my students and I produced...

[thiagostephan]

23 people play in the football team !!

[rlinfinity]

Can't believe you nerds thumbsed up my comment x54 times...

[neoxeo89]

Just awesome1

[bradkey98765]

Ah this is just what I needed to get me more motivated for group theory.

[ld43amat]

23 peaple has no idea of what a group is.

[adrianwatts]

continues to be total genius

[monobrowperson]

Anyone written a rhyming proof and rapped it?

[teresalipan]

AWESOME!



[Monomorphismus]

so great, i love it!

[Wasif1112]

best math song EVER

[drmathman]

Probably the best original math song on youtube! For a close contender, see "Derivative Rag".

[Mircel65]

Me encanta esta canciòn =)

[Mircel65]

Me encanta, muy buena :)

[olkjasdf]

I love this song^^

but i cant understand each word -.- can anybody write down the lyrics?

[impatboy]

stereotype confirmed

[pocketsizednerd]

love love love

[panchitajjjjjjjj]

GOOD

[kIzxuna]

can i have the lyrics? ^_^

[bavgil]

very good

[zxiio]

thats so great!!!

[zherui]

it's scary to know that the people laughing got the jokes too. that's got to be too much brainpower in one youtube video. :D

[mpd1989]

Works every time.

[deimos314]

i'm going to sing this to my girl this st valentine's day ^_^

[IAmTheNietzsche]

This is getting sung to my girlfriend asap. Anyone have the chords?

[IAmTheNietzsche]

I need the chords to thing song, asap. This is getting sung to my girlfriend.

[bogartnumbertwo]

Absolute genius!

[Pedrolisbao]

I just love how there are a couple tenured professors in the back.

That's how a good department should be, people can have fun at breaks, and everyone enjoys it.

[silvertrumpet16]

You know you're a math geek if you understand every word of this...lol I LOVE IT:))

[arvindleela]

I simply love this song, but clearly the Professors in the background are not impressed. Anyone disagree?

[littleredcait]

the laughing dude in the background is really annoying when you are trying to listen to them singing..

[Lampheader]

kumar/kal penn did this better

[LakatosIsti]

@Lampheader Nah, this is way better

[Lampheader]

@LakatosIsti it goes past nerd and goes into no life nerd

like if you haven't taken advanced math at a university level you don't get it (I have if you wanted to know >_>)

listen to the sperg laughter in the background

[michll89]

very good! i like that, very funny and a perfect harmony!

[crimmsonn1]

This is just annoying. Witty, but annoying.

[shoeginski]

"I'm not the smoothest operator in my class" haha

[zomgthesoftness]

My love for this song is like a divergent series as the limit of n approaches infinity! It gives me inspiration to finish that love song I've been fiddling around. :D

[rlinfinity]

@zomgthesoftness My love (L) for this song over the entire interval (t2=2:57, t1=0) is 100%. i.e. Given any ε > 0, such that if |t2 - t1| < δ, then | (dL2- dL1) / (t2-t1) - 100 | < ε

[ArsenalKid77]

these guys kinda look the guys from the first american pie

[gharik]

My love for you is like f(x)=x: continuous, unbounded, and strictly increasing.

[nairblin]

I'm a 2nd year Math student at the University of Waterloo, and I must say, this song was very well written. But strangely, yet I didn't get ALL the jokes; I say I missed around 5% of them.

Best Joke: I'm living in the Kernel of a Rank 1 Map (1:44)

Kudos and well done!

[SaraStarkid]

if me= 1, and you=1, me+you= 2 and as we all know, 2 is less than three, so <3,

the best I can do (:

[antizac]

@SaraStarkid aw that's awesome! I'm remembering that one

[ignatiusmontgomery]

that's awesome!

[aman1390]

So awesome, totally makes studying for Abstract Algebra more interesting.

[justapeachygurl]

It's all Abstract Algebra with a few Real Analysis concepts. And it's brilliant... Marry me?  All of you? Seriously. *sigh*

[twitcher64]

Finished a college Calc 3 class. Still don't understand most of this. I'm getting some Linear Algebra terms and Set Theory terms here.

[Chaostamer]

@IntenseSNEZZLIN A lot of the math here is more pure than applied, so you might not bump into much of it in engineering.

[6Diego1Diego9]

dorks

[KPhysicsGeek]

@6Diego1Diego9 Jealous ;-)

[cgtrgsm]

It should be a finite semi-group of order two because the elements are not invertible :-)

[dbernucci]

@cgtrgsm How about Z/2Z?!

[Wicked11235813]

Quality singing and intelligent lyrics. Nice.

[alliesong77]

awesome.

[oib4696]

Anybody have the lyrics to this?

[luisoncpp]

@oib4696 Check the description of the video with Id= UTby_e4-Rhg

[LoveCherryBoom]

Mmm, the guy in the middle (Matt Salomone) is hot. ;)

[dancerE44]

ahhhhhhhhhhhhhh i love this! thank you analysis and abstract algebre =P

love this!

[morron6666]

WOW the 5 squarest guys on campus, I found them!

[CaixetaArthur]

Lyrics please :]~

[cookerysolution]

I was just googling "Klein Group" as I forgot its precise definition. Then, I found this by accident. I will never forget it now, trust me. Hoping to understand all the puns by the time I finish my OU degree........ another ? years.....

[MrAamy87]

Hi !

I hope to join to this group . .

Because I interest to you . .

[snowyowl0]

I'm going to listen to this song every few months to see how many of the jokes I get. I hope that by the time I get my degree I'll understand the whole thing.

I just worked out "I'm getting tensor every day".

[TheOm3ga]

Subtitles please?

[lumaix]

KIll these scumbags please.

[navalicous]

this was so entertaining. i understood none of the jokes becuase math isn't exactly my strong suit but it was so catchy and cute!! good job guys!

[sclol707]

Hi i'm from northern ireland and studying further maths A Level. Part of the course involves group theory, which i find quite complex as i'm only 17 and learning this for the first time.

[AthlonNapelmanak]

Es tan hermoso, de verdad! Ya me dieron ganas de componer algo así!

Felicitaciones a kleinfour!

[jakstrike1]

This is beautiful.

[mayurgo10]

really like this, also can imagine the love graph from this

[dylwil3]

Freshman year: understand 2 of the jokes. Sophomore year: understand ALL of the jokes! Yay for category theory, algebra, and a bit of manifolds! Good thing there weren't many analysis jokes or I'd still be lost...

[tuerkek]

this is profound. if it's finite and simple, then one element is the identity, and the other operates on itself to get the identity. So this means if the girl masturbates, she attracts the guy, but if the guy masturbates, he only gets himself back since she doesn't wanna see that.

Who knew this song had such perverted implications!

[emilyorman]

will you be my ta?

[emilyorman]

i mean this in a strictly academic sense.

[granada60089]

As a math major, I must admit this is really F***ing histarical!!! I just listened to it like 314 times...

Love these guys

[davethebrave89]

Heart was open but too dense HAHA GOLD.

Woooo for understanding Math!!

[DionysusArt]

bahahaha tensor every day

[horseshavingfun]

Absolutely the best!!!! Thanks for sharing!

[maniacexpress]

This may well cause me to major in math and marry a nerd.

I ADORE this.

[f1vendetta]

The girl sitting on the steps is annoying as hell.  She keeps giggling like she has a clue what they're singing about. :rolleyes:

[maniacexpress]

@f1vendetta I don't know why, but that made me laugh quite hard.

*high five to everyone who understands this song!*

[Bambuseae]

@f1vendetta Maybe she DOES understand it and that's the reason she's giggling? We can not know.

[mkalime]

@f1vendetta sexism? Ahahaha

[obafgkmrnsxy]

Awesome job! Really!

[OoGMurfhoO]

Mr. Frank eats babies omnomnomnom

[MysticMoonGoddess67]

For a couple who's basis is with infinity......this is the ultimate way to communicate concerns.

[ieatyourbabiez]

I am in love with this song. For serious.

[clauriina]

@ieatyourbabiez me too :)

[JohnZ622]

ROFLMAO

[DrGenius73]

Awesome! Added to favorites! :D

[aramoticy]

Stars > 4!!!!

[QuepasaTanuvasa]

We need to get some nerdy Samoans singing this song. Represent nerdy polys!

[iwillown1243]

That was amazing. Very funny.

[rockbard]

Greatest song to ever mention the abbreviation Q.E.D. Awesome work, guys.

[simsima69]

these guys rock

[maydaychu]

awesome~~~

[allacesmax]

Tensor. Had me in tears.  Well done.

[Reminiscable]

I didn't notice that line until like the third time watching. Can someone explain the line, "Without loss of generality, I will assume that you feel the same way,"?

[MysticMoonGoddess67]

@Reminiscable i'm gonna take my best stab at this for ya. :) i believe that it means that it's working within a realm of real numbers (as in algebra), rather than imaginary number sets that set boundaries for the formula, ie infinity.

[allacesmax]

WLOG is our favorite way to sweep things under the rug. Just kidding. WLOG means the property you're about to state applies 'in general' - i.e. for any kind of problem of a similar flavor. The mathematical definition of "generality" is something best left to a real analysis II class - but - think about it like this: you can go from a specific example and conclude a bigger idea.

[sfernandez11]

@allacesmax A specific but *arbitrary* example, of course.

One of my professor's more amusing phrases is, upon going over a specific example of a theorem to be proven, saying something akin to: 5 is a general enough example, right?

@Reminiscable What allacemax said. They're saying something quite close to my professor's joke. (he's not an arbitrary example, similar to 5 not being an arbitrary prime)

[ljwrr]

awesome!!

[narcissusgray]

They integrated from the very point of origin. Her curves were continuous, and even though he was odd, he was a real number. The day their lines first intersected, they became an ordered pair. From then on it was a continuous function. They were both in their prime, so in next to no time they were horizontal and parallel. She was awed by the magnitude of his perpendicular line, and he was amazed by her conical projections.

[narcissusgray]

"Bisect my angle!" she postulated each time she reached her local maximum. He taught her the chain rule as she implicitly defined the amplitude of his simple harmonic motion. They underwent multiple rotations of their axes, until at last they reached the vertex, the critical point, their finite limit. After that they slept like logs. Later she found him taking a right-handed limit, that was a problem, because it was an improper form.

[narcissusgray]

He meanwhile had realized that she was irrational, not to mention square. She approached her ex, so they diverged.

[craigpeters87]

it's klein 4 from group theory in mathematics, just like half the song. klein 5 doesn't make sense.

[Crystalwaa]

I LOVE IT!!!!!!!!
