/sci/ - Science & Math

Don't you hate pants?

is 0.99999* == 1.

>>4066465
Yes

Which semester are you in?

>>4066467
Yes.

>>4066471
I'm not exaclty sure what semester means, but i'm in my 3rd year, and it is currently michaelmas term.

Are you religious?

was it difficult to get accepted? i major in math as well at my local university

>>4066483
Nope, though there is certainly a higher number of religious people here than is average in the UK.

>>4066485
I had interviews, then sat the STEP cambridge admission test. As far as it being hard, I don't know, difficulty is relative to the person, but it was certainly easier to get in than it is to keep up with the material

Which is lim x/0 equals ∞ as x->0?

I never really got this? That means 0 multyplied by something (infinity) equals something?

Analysis or Algebra which do you prefer?

>>4066492
I don't understand what you're asking. It doesn't really make sense to say a limit equals infinity

>that feel when you'll never do part 3 or a PhD and make 300k starting

If 1/0.00000000000000000000000001 = 1.0 × 10^26
and so on, does 1/0 = ∞ ?

>>4066493
I think I prefer analysis, though at the moment i'm moving my studies into mathematical physics.

Are you an IMO candidate?

>>4066502
If 1/(-0.00000000000000000000000001) = -1.0 × 10^26
and so on, does 1/0 = -∞ ?

>>4066502
no

what college are you in?

>>4066498
I mean if you say 10/x equals ∞, that means 0 multiplied by ∞equals 10.

So you take zero something, you multiply it by something and you get 10, right?

That means zero is not zero, as its not "nothing"

>>4066504
no certainly not. I'm not one of these ubermaths geniuses, though there are certainly some of those about. I'm just relatively hard working, and maybe a little bit of spark to help me on my way

>>4066514
>10/x equals ∞

here's your mistake. That expression doesn't make sense.

>>4066523
Yeah, but why not?

Prove/disprove the Goldenbach conjecture.

DO IT FAGGOT

>>4066528
because infinity isn't a number. It's not well defined in the field you're working in. Because we have infinity+1=infinity, it has to be isolated as a special point.

A more concrete way to define infinity is to look at the extended complex plane and the riemann sphere, look it up.

What do you think is the closest thing we will get to a Grand Unified Theory?

>>4066537
I'm not sure. We have no hope of unifying everything when we cannot even work out gravity on it's own yet.

>>4066534
Well my original question was how come you cannot divide anything by zero?

Is there a specific reason for that?

>>4066517
Smalltime.

>>4066547
Can't blame me for trying.

>>4066546
Consider lim 1/x as x ->0 from above, then from below.

They are different. this isn't any rigorous argument, but it will perhaps show some problems in defining what 1/0 is

>>4066546

You get contradictions, if you don't treat it specially and all the best laid axioms fall to pieces. I suggest you look up the axiomatic definition of a field and see what happens when you divide by zero.

Did you get a scholarship or how are you paying the ridiculous amount of money they ask of you?
Is it worth it?

>>4066561
>Did you get a scholarship or how are you paying the ridiculous amount of money they ask of you?

Firstly, as a UK student, I'm only paying small fees.
And secondly, since i'm from a 'poor' family (so poor we own a piano and computers and stuff, oh woe is me) that I get everything payed for, and then some. My bank account is currently filling up with the grant money.

U.S. Comp Sci/Mathematics major here. Do you smoke weed? Also are you planning on applying for graduate programs?

>>4066576
Don't smoke weed. I'm looking into applying for PhDs after I complete part III, yes.

What's the hardest maths course you've taken thus far?

Can you teach me groups? Saxl is a shit lecturer

How much time do you study per day (exluding lectures)?
How is that time distributed between reading/doing excercises/doing projects?

>>4066585
Analysis 2 is pretty hard, though currently Electrodynamics is the hardest I think.

>>4066596
Saxl is a great guy, but yeah, grab algebra and geometry by beardon.

Cambridge confirmed for retard tier.

>>4066602
study maybe 8-10 hours.
It's all just problem sheets. Computer projects I do outside of term time.

>>4066611
That's just the name of the building since it houses all forms of mathematical sciences

>>4066609

I'd say maybe 40

How old are you?
20
What are you studying, exactly? Pure math? Applied math? Finance?
Applied maths and theoretical physics

What do you plan to do with your degree once you graduate?

PhD

How in fuck does anyone manage 8 hours of studying a day? I can do six, but fuck eight.

>>4066637
it's difficult, but the term here is shorter than most places, so we need to learn it all quicker

What was your score on STEP?

>>4066647
i got 1,1 in step II & III

how many people from the natural sciences tripos take your level theoretical physics in your year?

>>4066657
I don't know, some people in NST do some courses from the maths Tripos

What are the requirements to be accepted as a graduate student in Cambridge?

Currently a high school student in college, just started studying math.

How would you say your knowledge progressed through your years of studying? At what ages did you grasp certain subjects?

>>4066666
Get quints every post.

But generally you need to be in the top of your year at whatever university you're in. Some offers for PhDs in the maths department are given by "getting in the Top 5 of Part III candidates"

Why are you studying this? Do you have a passion for maths or for success?

What was your upbringing like? Well-off family? Were your parents well educated?

>>4066667
My knowledge blossomed mainlythrough self study over my summer holidays. it's suprising how much just an hour or two a day over the holidays builds up

Are you aiming for a PhD?

>>4066667
>hs student in college

fuck that was retarded

16 in college

>>4066675
I enjoyed maths, I enjoy physics. I am not driven by money or success, just in interest and the intelluctual challenge.

I'm not from a well-off family. My parents earn slightly less than the average wage in the UK. My parents dropped out of school at 14. They are not educated in a formal sense, but they are not stupid. My father in particular has a sharp common sense

>>4066684
Yes

>>4066686
Do you believe in the validity of IQ testing? What's your IQ, Billy? May I call you Billy?

>>4066461
Does your dick ever get sore from fucking all those hot chicks?

How do you even get time to do maths with all those bitches on your jock?

>>4066686
Did your parents coerce or encourage your academic performance?

Does it feel awesome to study in the best university in the world?

>>4066691
IQ testing is a measure of something. Certainly not intelligence, but it measures something which is part of intelligence. My IQ when I was tested 10 years ago was 137. You can call me whatever you like.

what a-levels/ grades did you get?

>>4066695
Blowjobs with the girl under the desk. Study whilst spooging.
>>4066696
no, my parents were completely shocked that I was smart. they certainly didn't deliberately encourage me, but I always loved brainteasers so they got me a book of brainteasers when I was young.
>>4066697
feels good man

>>4066699
AAAB,

A in maths, further maths and physics.
B in psychology >implying i tried

I got full marks in most of my modules in maths, further maths and physics, except for those damn statistics bullshit. and Physics practical exams.

What's the worst you've ever performed in a subject?

Did/do your peers consider you a nerd or are/were you popular?

your favorite books/writers/movies? (atleast 3 of each please)

What boards, besides /sci/, do you usually browse?

>>4066713
I got a D in design and technology lol

I'm not considered a nerd. I wasn't popular, but I was liked. I wasn't like a nerd, sitting at the front of the class answering all the questions. I skipped lessons all the time, usually to study on my own because it saves time.

>>4066704
>Blowjobs with the girl under the desk.

So you together with a girl gave some guy a bj under the table?

>>4066718
I browse /v/, also /pol/, sometimes /fit/ when I need exercise motivation
>>4066715
Don't really read books, don't know writers, not a movie fan.

I'm applying to Oxford for maths. Any tips for interview preperation?

>>4066722
No, the girl is under the desk sucking my pork sword whilst I do some complex analysis

>>4066722
>jealous troll is jealous

OP is a god with the ladies and makes 300k a year! Stop hating!

>>4066725
1+1=2 should get you into oxford
but seriously, just read some interesting maths problems, make sure you know all the alevel stuff you've learnt already

>>4066727
Hahahaha, no. You're a lonely neckbeard obviously NOT going to this school, or anything. Way to tell us your fantasies, though, bro.

>>4066731
I was just playing along, you can believe what you like, that doesn't effect my reality.

>8-10 hrs a day studying.

Damn, nigga.

Damn.

I'm a mathematics major as well, but I don't even study that much. I normally study about 3-4 hrs a day, per day. Not that much. Jesus. That's heart.

So what do you think your starting salary gonna be?

>>4066730

Idgaf, cambridge might be a better uni for maths, but not by so much that it's worth doing STEP. Plus I prefer the city by far, and in the finance world Oxbridge are equal. Gonna find out if I got an interview on Monday/Tuesday, kind of shitting myself.

A level shit is fine so far. Any specific website that you can suggest? I've got the BMO next week so I guess preparing for that will be good prep...

How are students selected to represent Cambridge in IMC (International Mathematics Competition)? Why did you get such a poor result last year?

Why would you use 4chan?
I think that it may be special in that it's anonymous, but otherwise it's a horrible website and people aren't kind to each other.

>>4066738
>hrs a day, per day.

Meant hrs per day. I don't even know where 'a day' came from. Silly subconscious.

Son Im disappoint. Why no study to explore the universal truth about reality?

>>4066739
300k, once i've done my PhD
>>4066740
BMO prep would be fine
>>4066741
I don't know, no one here cares about those competitions
>>4066742
I find it funny. I like discussing politics without having people say "RACIST, RACISTTTTTTTTTTT" just because i say immigration isn't our salvation

>>4066748

I love maths and how everything fits together so elegantly, however I don't want to be a poor motherfucker. Is that a crime?

>>4066750

Right, well wish me luck.

>>4066750
>Phd math
>making 300k a year in this economy

Lawl you'd be happy if you got a job teaching algebra to elementary school children

>>4066754
I plan to do research, maybe lecturing, maybe i'll fail, who knows, but once I have a PhD i'll be able to get a decent job somewhere

>>4066461

Math is not a universal truth.

It's a convenient truth, with a lot of loop holes.

I´m 21 and I MIGHT go to university once I´m 23 and I MIGHT study something with real science in it.

Feels Inferior, but at least I have a virtual life.


Do you speak any languages besides English?

>>4066763
Yes, we do.

>>4066772
>Yes, we do.

Seriously? Explain.

>>4066771
I have a life, it's just on hold. My friends who have started their PhD say it's far more relaxed than doing the degree here. They have time to do lots. Also outside of term I do plenty of things.

>>4066764
What is that? Do they apply quantum mechanics into economy? And why only math phders can get that job?

>>4066775
Sorry, but my overlords do not permit releasing such information

>>4066780
Quant is a quantitative analyst. Nothing to do with quantum mechanics. And basically it's just shit hard equations, and they need people with experience in mathematical research. Physics PhDs can also do it

>>4066784
C'mon, just give us a taste. Something kind of interesting, but not necessarily secretive. Also, is there such a thing as an infinitely countable compact metric space?

>>4066789
Yeah nvm I figured that out after reading the link. Anyway enjoy spending your soul crunching numbers so your Jew overlord could fool people their hard earned money

>>4066793
i can't say I know much that much about metric spaces, so i can't answer

>>4066780
"from quantus "how much,""

>>4066778
Thanks for making me feel even worse. I fucking hate you and I want you to know it. I hate you because you have more success than I have and I would like to beat you up for personal satisfaction. You stupid piece of shit.

I feel already a bit better, glad that we talked about it.

And shouldn´t you be learning NERD!

>>4066807
I'm not the person interested in becoming a quant, that's the faggot ass munching oxford applicant (no offense to him)

How do you feel mathematicians are responsible for the financial crisis with their failed speculation and pseudo equations

>>4066845
Couldn't give a fuck.

>>4066817

Suck my dick, shitfaggot.

gcse grades? how many A's B's and so on

also, cabridge, posh?

>>4066853
GCSE grades:

3A*
5A
B
3C
D

Cambridge has two sorts of groups really: People who study arts subjects are posh wasters. people who do science/maths come from the whole spectrum

What book did you use for Complex Analysis? Would you recommend it?

>>4066988
I didn't use a book, but I can recommend Complex Analysis: A hitchhikers guide to the plane

>>4066993
what a babby book

>>4066993
needham's visual complex analysis

>>4067008
As i said, I didnt use a book, i have just been told good things

May have been asked this, i dont know didnt read the whole thread.
What previous schools did you go to??
What were your A level grades and in what subjects?
I know the schools in that area

>>4067016

>>4067018
The answers are already in the thread

>>4066868
Shiiit, bro. Apparently the average Oxbridge applicant has about 5 A*s at GCSE, is that true?

Congratulations on beating the odds and getting to the best university in the world.
Were you parents rich?

>>4067021
Did you win any special competitions that helped you get in?
Where did you undergrad?

What type of research are the professors doing in mathematics?

>>4067049
I don't care about the admissions statistics
>>4067050
Thankyou. My parents are not rich.
>>4067054
I won no competitions. I am still an undergrad.

Proffessors are doing research in most fields spanning all of mathematics

>>4067065

>>4067077
Yes, i am

What extra-cirricular activities did you do related to maths that you put on your application.

>>4067083
None.

>>4067065
Do you know any international students?
Specifically from America?

All these terms like A-level are foriegn to me

>>4067086
I don't know any american students, no. Alevel is essentiallu pre-university qualifications, you'd typically take your Alevels at 18

>>4066468
Why?

what interests you besides math?

Have you ever taken an IQ test?
I don't need results. I'm just interested how do Cambridgeans feel about this whole intelligence measuring.

>>4067093
I like music, and video games

>>4067103
Not since I was 10, read above. Also, I don't think IQ tests are very good at measuring intelligence

would you say it's worth it for an non-uk student to try and apply to cambridge? i'm currently in IB, do you know anyone from there getting to cambridge? also how much does it cost, and whose dick do i need to suck to get a scholarship?

how much do grades count when applying, and what other factors affect admissions?

>>4067105
What kind of music?

Post the current hardest problem you have solved. Please no 1+1 bullshit.

>>4067118

C calls out that he is wearing a black hat. Why is he 100% certain of the color of his hat?
After a while, C comes to the realization that he must answer.

This is because D can't answer, and neither can A or B.

D can see C and B, but can't determine his own hat color. B can't see anyone and also can't determine his own hat color. A is in the same situation as B, where he can't see anyone and can't determine his own hat color.

Since A, B, and D are silent, that leaves C. C knows he is wearing a black hat because if D saw that both B and C were wearing white hats, then he would have answered. But since D is silent, C knows that he must be wearing a black hat as he can see that B is wearing a white hat.

>>4067144
C, right? He knows that if D saw two same hats it would make him shout out, and therefore the fact he didn't means they must be different. If the guy in front is white that means he must have a black hat.

>>4067149
Ha ha. Not being able to give a one word answer to a simple logic puzzle. Have fun flipping burgers.

Why don't you look at the question? It's not like you could be better using your time here.

>>4067206
Look at it, it's a pretty interesting (albeit simple) logic problem

what's the workload like? The son of someone I know is taking maths and apparently has no free time whatsoever. I'm sceptical.
