  • at 0:35 he's wrong.

    The 'c' is the longest side, so it's a^2+b^2=c^2, not a^2=b^2+c^2

  • @hejjagedu just because in maths textbooks c is generally set to be the hypotenuse doesn't mean he is wrong. he's still right. there is no law the c has to be the longest side (as far as i'm aware)

  • 'Am I going to asphyxiate by half past twelve?'

  • The way he says tissue makes me cringe...

  • @The505Guys That's the correct way of pronouncing tissue.

  • 'It has a periodicity of four hours...'

    'Oh, the left will be in charge from 1 'til 4...'

    Yet more evidence that David Mitchell struggles with mental arithmetic. I love the guy, but he's made a lot of errors like that.

  • @1000thson maybe his right nostril was in charge there :D

  • In another universe, Fry be a teacher and the world... his students.

  • this is GOLD

  • You are now manually breathing

  • @BambisaurusRex FUCK!

  • Fuck school, QI is where it's at.

  • People were really arguing about maths on here?

    Jesus, I don't care about maths, I'm just here to watch Alan stick a tissue up his nose

  • i want a full ep...

  • but what if you do horrific amounts of cocaine...then what?

  • @Putaspellonyou you may get thicker.. due to either this or the fact that you doing coke in the first place..

  • The pythagorean theorem is just a special case for right angled triangles.

  • @Magnetohydrodynamics Did anyone say differently?

  • i should probably schedule my exams for the next semester based on my nostril patterns.

  • What are lamberts?

  • @Diazreta fags/cigarettes

  • It annoys me that no one pointed out that the nostril thing is more likely to be a sign of alternation in the brain, not the cause of it.

  • @GGov86 Very true. Some have seen it as further evidence of the "aquatic ape" theory of human ancestry, citing similarity of the sleeping processes of cetaceans where one hemisphere of the brain swaps reduced function in turn with the other, matching the typical four-hour REM sleep sub rhythm of a typical 24-26 hour mammalian circadian rhythm. All of which could,of course, be bollocks. :)

  • @alanpgoodwin Cool, I'd completely forgotten about the aqua-ape hypothesis. Seems a bit far-fetched, though, that (at the most) semiaquatic early humans would've had the need for a sleep pattern similar to animals that spend their entire lives in and under water. If my memory serves me correctly, "bollocks" is one of the kindest expressions most evolutionary biologists use regarding the theory, so I wouldn't be surprised if such a claim had been made :)

  • @alanpgoodwin "Further evidence". LOL. 'Bollocks' is the best word to describe the aquatic ape idea and almost every one of their claims. I've been involved in a multi-year online 'debate' on the aquatic ape idea. It is still really funny to see it mentioned elsewhere in the internet.

  • @ericv00 What was the clinching point for you to come out on the negative side...or did you go in with a preconception and stick to it?

  • @alanpgoodwin There was no 'clenching point'. The evidence just stacks up more and more and more against it. It really is best to start with an AAT claim and logically follow. The biggest single subject to kill AAT, IMO, are the Ardi papers.

    Like most people, I went in sympathetic to the idea. People WANT to be on the cusp of a paradigm shift. But if one seeks knowledge through logic and reason (and facts), AAT will ultimately disappoint.

  • @ericv00 I'm still not sold one way or the other. The important thing for me is that such ideas are discussed, opening doors rather than slamming them. The "AAT" piqued my interest when I read of the quite vicious way in which poor old Elaine Morgan was slated and her ideas dismissed almost purely because she was a woman. It occured to me then, as now, that the scientific community shoots itself in the foot a lot by treating 50% of the population as brainless just because they're dickless.

  • @alanpgoodwin "in which poor old Elaine Morgan was slated and her ideas dismissed almost purely because she was a woman" This is most definitely NOT TRUE, though she does love to try to paint that picture. Instead of talking about poor old women, you should be looking at facts. Elaine gets most of her "facts" wrong. THAT is why her opinions are dismissed. She has never done a study or written a scientific paper on the subject. She only has anecdotes, personal opinions, and errors.

  • If you are interested in the idea, first examine a claim, not someone's attempt to persuade you through saying they've had a personal struggle. Science cares about facts, not sex, age, or strength of opinion. State one. State any claim that the proponents of AAT use to argue for AAT. Hell, send me a personal message so I can say more than a blurb, and we not be spamming this video with AAT nonsense.

  • Stephen's nose was broken, so does that mean it might have equalized his nasal breathing thus making him AWESOME! :D

  • actually, it's a^2 + b^2 = c^2

  • @phantominkheart just remember the letters are variables so you could plop down any old letter or array of characters you felt like to represent it

  • Tih Sue?

  • @phattown213 Tis-Sue pronouncing both S's.

  • WTF are we having a debate on pythagoras's theorem It's a comedy not a maths class like I didn't have enough of that in secondary school ¬.¬

  • im on my left side right now

  • Who actually tried this? Thumbs up.

  • Does nobody else find it awesome that we have four intelligent men randomly sat there chatting away with clods of tissue up their noses?

  • what's 3.14159 vaginas?

    hair Pi

    heheh

  • i love the way he says tissue

  • I'm sick, and one of mostrils is blocked.

    I'm screwed in four hours.

  • Tiss-yu

  • That's a Ninja trick for telling time. They'd write down when they were breathing through a particular nostril and memorize the timetable, then throughout the day (or night) they could get the general time of day by checking which nostril they were breathing out of at the time.

  • until the ninja watch was invented............

  • @thesteveus I bought one of those, but now I can't find it.

  • why complicate things with math, it's rubbish. I want to know why we (and most creatures above the size of a zygot) have TWO nostrils? what's the purpose of two nostrils, why isn't it one big nostril?

  • yeah, like Stevie Nicks............

  • @Dinostra I looked it up. The reason we have two is that the more blocked one smells different things to the lesser blocked one, giving you the ability to smell different textures than if you just had one.

  • @ChristopherDone Nice =) thanks i guess hehe =) Is it because some textures are too hard to differentiate from each other that we have to separate the glands or buds or whatever? GAH! now i have to look that up haha, but thanks for taking time to finding it out and posting it!

  • Erm, isn't it a squared plus b squared equals c squared? If you wanted to isolate a squared, it would be a squared equals c squared minus b squared.

  • @wander099 yes, because c refers to the hypotenuse :)

  • David said "1 till 4" but that's only 3 hours :P

  • @Clarestovold Well his math-intelligent nostril was blocked.

  • @vampirechickita Hahahaha good point XD

  • There is something fundamentally wrong about seeing David Mitchell with a tissue stuck up one nostril.

  • this is interesting and all, but you try explaining to your teachers that the reason for you failing an important test was because the wrong nostril was open for the type of test..... :s

  • "Now say something intelligent" *silence* "Erm..." ... =L

  • With a tissue sticking in your nose, I don't think anyone can come up with something intelligent to say. ^^

  • @Yora21 I don't think anyone would take someone seriously with a tissue up thier nose, even if they did say something intelligent. :)

  • Holy shit, I never knew that! I'm breathing mostly through my left nostril at the moment XD

  • @EnigmaDrath how bout now? :p

  • wheres the rest of the show, i want to know the difference in the thinking/nose-breathing-side

  • @shanethewolf

    go to your big brother then. most people find learning interesting. obviously your too stupid to appreciate that

  • @WasLilChrisnowbigish Just because I don't like filling my head with boring trivia doesn't mean I don't like learning. I'm more pragmatic and believe that useless clutter is not good for the brain.

  • lol were any of us THAT passionate about maths when it was all happening in high school? hehe

  • Hm... I'm breathing through my left nostril right now.

  • seriously? the genius that is david mitchell at the end and all you people can talk about is the systematics of an equation, which incidentally, as brokenbrilliance has already pointed out is entirely dependant on which side of the triangle you label?the labels i use are h2 = a2 + b2. (i don't know how to do squared signs on internet browser, my usual method just magnifys the screen) with h being the hypotenus, and a and b representing opposite and adjacent. in his, a = hypotenus. not a big deal

  • @filthmonger171 Don't have a go at me, just using my Year 9 maths knowledge xD.

  • Funny says 'tissue' funny

  • for those of you arguing about maths. all that matters to me is 20 lamberts are 5.19 if i have a tenner it means i get 4.81 change

  • @rogerthat155 I like how you're watching QI and then profess how you couldn't give a shit about maths. It's astounding. 

  • @rogerthat155 yeah, back in the glory days when cigs cost that much!

  • it's actually not the equation he said. it is a²+b²=c²

  • Actually, you're an idiot. It can be done any way. The hypotenuse is usually labelled as c, but that's not necessary, and you could be trying to find one of the other sides labelled a or b.

  • Oh please. It is completly dependant on which side you lable. The hypotenus is on one side and the adjacent and opposite side.

    tomcarvell, brainwashed into one way of thinking (Y)

  • @tomcarvell it could be z^2 = FDT^2 * theta^2 if you wanted it to. It doesn't matter.

  • Can I have your babies?

  • @LordConflictIGN get out much?

  • @LordConflictIGN You're half correct, if you were trying to find one of the sides you'd had to subtract from the square of the hypotenuse rather than add.

  • @ReecioG Ah, good. I was just about to post the same thing but then I had a look and found YOUR reply.

  • @isbourne hehe, sorry, beat you to it ;)

  • @LordConflictIGN The beauty of algebra :D

  • @LordConflictIGN Yes but which nostril did you have the tissue in haha

  • @LordConflictIGN Damn straight :D

  • lol

  • very funny

  • Lolwut

  • You idiot.

  • You're welcome ;)

  • Np :).

  • : )
