[@vivekbodh2096]

seriously.. plus it would not be square root if there are three numbers..

[@nicosmind3]

I love the mixture of "I feel dumb as fuck" and "these fuckers can't even divide in binary" in this comment section.

[@janderson2709]

People with decent level specific maths and physics knowledge commenting 'this isn't that hard for university'. Um yeah, the point of this show is to test the contestants with specific knowledge over a wide range of topics. The fact you knew Pauli was responsible for the exclusion principle doesn't make you smarter than these guys. That's a specific piece of knowledge to that subject, which isn't general knowledge - and that's the point of the game.

[@ericzhan3454]

Eh, you'd wonder why these teams don't put at least one science-oriented person on their team, though.

don't worry they also make really stupid mistakes 15:39

[@ericpelton6941]

and when talking about geometric means. he gave them the definition and like 2 questions later asked what the GM was of 2, 5, and 100. they got it wrong lol

[@pranavmisra155]

eric pelton And the girl says its a positive root.

[@andresjrz99]

Many of the questions just require knowledge/memorization of terms, theories, and history of math and physics.

[@eliluong]

don't worry. no real life application :P jk they live, breath, and eat math and physics.

Karl Pilkington has got this sussed! He enjoys playing University Challenge at home, not by answering the questions, but by guessing which egghead will answer each question. Genius!

[@reconbravo104]

Egg.

[@theMrFouldsy]

20:07 that was harsh! Nuclear Magnetic Resonance and (nuclear) Magnetic Resonance Imaging are the same bloody thing.

[@peterwhiteman2122]

Harsh yes, but Paxman just went with the answer on his card. He isn't a science graduate so how would he know??

[@realmtraveller]

not necessarily MRI is an application of NMR so they may wanted the base concept, but yh kinda harsh

I was pretty surprised that Brits did not know about Ramanujan. I thought he would be famous there since he visited Cambridge.

[@tomgreg2008]

HYPERsemiconductors. WOW.

[@99bits46]

the close ups are funny

[@p0gr]

were they required to send their people who know the least about the subjects? who doesnt know the geometric mean or ramanujan? 10^(-1)=-10?

[@ToWnHeAdAARON123]

U mean - one tenth?

[@p0gr]

21:45 see, even lingling know the correct answer.

[@fosheimdet]

Yeah, but they are under allot of pressure. Its easy to mock their mistakes when you sit at home watching. That said, not knowing about Ramanujan is disgraceful.

[@khalilhijazi4588]

Still even under loads of a pressure, I'm pretty sure u can still realize that any number raised to an exponent is essentially positive. So why in the world did he get -10??

[@sevenwhatuknow]

Sorry, I'm just a dumbass bug but, I have no idea of that

[@tomgraham7168]

It was actually hardy who thought his cab number was uninteresting, and srivinasa said that it had those properties, or as the story goes, just goes to show these guys who don’t even study maths (most of them) still have heard of these things which I find so impressive, I only came here because I’m a maths student (with a keen interest in physics my diss is on star formation) to see whether I’d get many of them.

[@arcanechili]

That was a great deal of fun, but I have one tiny nit to pick (with the questioners). "Heisenberg's Cat" doesn't actually say that "the cat is simultaneously dead and alive" (although this is how it is often posed). Rather, it claims that the cat is _neither_ dead _nor_ alive until the measurement is made.

[@adrianwright8685]

it was Schrodinger's cat !!

[@NichaelCramer]

@@adrianwright8685 : Ah, of course. (Duh) I'll change it in the message. Thanks.

[@amesakurako1]

(Rant) I have a degree in maths and from personal experience, I think the actual computational maths problems are all around A-level maths/further maths standard, like something you would get in a Cambridge maths interview. Like the linear algebra/ Taylor expansion/elementary probably theory stuff which is further maths. On the other hand the knowledge based questions are pretty specialist (90% from 1st year material with a few harder exceptions) but you don't have to work anything out. The exceptions include the v-e+f=2 Euler equation I learnt in 3rd year discrete maths, and Cauchy, Laplace etc whose names I only got to know in 2nd year. I remember from another episode a question about the Lebesgue/Jordan measure which is definitely 3rd year probability theory. The other things like Mersenne primes, Riemann Hypothesis etc are basic knowledge for all keen high school students wanting to pursue mathematics. Also I managed to answer 4 physics questions from remembering my A-level physics classes, so I think they must be around the same level. This makes me feel much better now since most of the time I don't even understand the questions on the show that's not maths or classical music. But I guess it's manageable for people who study that particular subject. I'm still amazed at how these guys do maths problems so fast under pressure though👍🏼

[@diebereitschaft8963]

You heard about Cauchy in your second year for the first time? This dude came up with the foundation of Analysis. If the Mathematics program you attended does not cover Analysis I (including among other topics: construction of the reals, sequences and convergence, (infinite) sums, continuity of functions, differentiation) it has to be a very shitty program.

[@amesakurako1]

+Sheldon Cooper I think I meant to say the Cauchy-Schwarz inequality (and Laplace transforms), but shortened my point incorrectly. I know that some unis like Oxbridge teach it in first year, but as I did a combined degree we learnt it in 2nd year real analysis. Also would you like it if I were to call your degree shitty? We are all grown ups so please speak in a civil manner. FYI rankings tell me that my uni is one of the best in the world so I'm pretty sure the courses I took were far from 'shitty'.

[@billwindsor4224]

+amesakurako: Great writeup, thank you. +Sheldon Cooper: stop the dumb trolling and get on the University Challenge program to prove what you know in a competitive pressure situation.

[@ralphinoful]

A lot of the questions are meant to just be really quick, off the cuff answers. I mean... One of the questions they just sounded off the definition of continuity in a topological space. I can't imagine they've never been exposed to it, I'm guessing it was nerves.

[@alex1stamford779]

@@ralphinoful Hearing topological space and answering convex or concave means that they are guessing with whatever words they learned in preparation. Convexity has more or less nothing to do with topological spaces (unless you are in a convex topological vector space).

[@DeeandEd]

Everyone here in the comments is wondering how they didn't know Ramanujan or Tesla, and I'm over here wondering how the fuck they didn't know the secant question. That's basic high school geometry/trigonometry.

[@MathNerd1729]

47:04 Also, they did not realize that (m/s)² [velocity squared] does *NOT* give the same units as m/s² × m³ [acceleration times their answer of radius cubed].

[@Apollys]

This is actually so much easier than I expected lol

[@p.s.design4338]

to be honest, most of the questions are really simple.

so now they can't do basic GCSE indices?

[@lucasm4299]

Linear algebra was thrown in the trash. Eigenvalue, trace, determinant

[@sanketkulkarni7854]

[@sw0inThoughtSeize]

Lots of keyboard warriors in the comments. I also got most of these rights, but when you're filmed and under pressure I guess it's a total different story. By the way science is about being amazed and trying to understand the world around you, it's not a dick size contest. Stop being so full of yourselves

[@jakejakeboom]

Also, this is angeneral knowledge quiz with the non-science questions edited out. I think a lot of these students are non-STEM.

[@thegreatreyrey1]

45:40 How the hell do they not know Tesla?

[@seleneker]

🤯 I agree with you

[@colinyoung3685]

Maybe when you have such a vast pool of notable scientists stored mentally, selecting the correct answer becomes less trivial than when only knowing the most obvious select few. That, or they be dumb.

[@advayiyer6456]

its not meant to be university level questions, rather such a broad variety of questions that it is very difficult even for university students. Also just because you may have answered these, dosen't mean you could compete in this as you need to know many areas (from maths to classical poetry) to even qualify for the team of most unis

[@irinaa09]

Can someone please explain to me why the answer for the question starting around @24:40 is 3? My very fast guess would have been 0...(not considering negative integers though).

[@alis1637]

By Bezout's identity, the smallest positive integer that can be written as 375a + 147b (where a and b are integers) is also the greatest common factor of 375 and 147. They obviously share 3 and dividing 375 by 3 gives 5 cubed. Since 147 is not divisible by 5 and 375 has no other prime factors (as 3*5^3 is its prime factorisation), the greatest common factor must be 3.

[@irinaa09]

Thanks. You are completely right. I missed the point that he said "the smallest *positive* integer".

[@tagorewithlyric4394]

Just gonna say: hapax legonmenon

[@TheLarsRosen]

Why did they throw in some high school chemestry questions?

[@gnamp]

How can there be a probability of 1 (ie certain to occur) that one of two half-possible events will occur (of two mutually exclusive events, each with only a probability of one half of occurring)? When say there's half a chance that coin A turns up heads when flipped- and half a chance that coin B turns up heads- it's DEFINITELY not certain that one of them will show heads. I must be misinterpreting the question.

[@amritlohia8240]

He said mutually exclusive events (i.e. events which can't both occur at the same time), and the events you described are not mutually exclusive.

[@felipea.barretto7503]

[@123string4]

At 26:12 the guy get's it right but the host says he's wrong. The question had both metres and centimetres and the answer was 10cm but the contestant likely converted to meters (as any physicist would) and said the answer was 1/10 (of a metre) but the answer the host had was 10 (cm). The question didn't say what units to use.
