@0celo7 it's too complicated

@MAFIA36790 she doesn't use skype.

barely any one i know uses skype

@3075 what

@0celo7 she likes science.

I go to the library all the time with my gf but we're nerds

@Danu oh no you can't say that and leave it

That's just mean

yeah

@mafia no..

Sending a girl a gift for no reason is weird.

lol

@0celo7 Since when have you realized you're a nerd? oO

@Danu Perhaps you could draw a diagram in TikZ so we can try to understand it :P

@ACuriousMind I'm not.

Did I say I was?

"but we're nerds"

Oh I misspoke

She's a nerd, yeah

I just stare at books

lol

Right, staring at books is a perfectly non-nerdy activity

@ACuriousMind I'm not a nerd.

@3075 So you have a few options

Most of which are bad

Just like you're not a physicist, got it :)

So she has a BF and you'll never see her again in 2 months?

@mafia she might remember you ;))) what a master plan lol

@0celo7 yeah.

@3075 do you know if she likes you

idk

@MAFIA36790 yeah

guys I don't think this proposition is true. Who is with me? if $|x| = n < \infty$ then $|x^a| = \frac{n}{(n,a)}$. let $d = (n,a)$ so that $dk = n$ and $dc = a$. Then, $(x^a)^b = x^n = 1$ so that $x^{ab} = x^n$ and $ab = n$, $b = \frac{n}{dc}$

@3075 ok so unless you're a Greek god you're not going to get with her

@0celo7 what does that have to do with it?

and don't be so negative.

@Obliv What part of that is the proposition, exactly?

And you have to be a good looking one too, not like that one forge God

@ACuriousMind

The lame one

the part before let $d = (n,a)$ @acuriousmind

@0celo7 Hephaistos?

@ACuriousMind Sounds right.

@3075 I'm not sure what you want

What do you want

@Obliv Okay. That proposition is true. What is the part after that supposed to do?

show that $(n,a) \ne dc$

er

@ACuriousMind how do you know that it's true

What does the notation $(n,a)$ mean?

gcd of $n,a$

@0celo7 there has to be a way.

@3075 for?

if I'm showing that $d = (n,a)$ then how could $d = dc$

unless $c = 1 \forall c \in \mathbb{Z}$ meaning $a = d$

gcd = greatest common devisor?

@0celo7 to be with her.

yes

@3075 there are ways. Not entirely legal ways.

^

lol...

Nothing above-board that I can see

@Obliv: $\frac{n}{dc}$ is not an integer.

(Unless you're a Greek god)

So raising $x^a$ to the power of $b$ doesn't make any sense.

@acuriousmind what must $b$ be, then?

@3075 generally speaking girls aren't stupid, so she knows you have the hots for her. And she has chosen not to do anything. That tells you all you need to know. Sorry.

well that's depressing.

@Obliv I don't understand the question. But if $d$ is the gcd of $n$ and $a$ and $dc=a$, then $\frac{n}{dc}$ is not an integer unless $c=1$.

@ACuriousMind Measure theory via rectangles is thoroughly unsatisfying.

The proofs are all tedious and not slick at all.

@3075 most relationships start withing five minutes of the two people meeting. The idea that men have to use all their manly powers of seduction to entrap the love of their life is a misconception that women are willing to put up with to indulge men. The women have normally decided more or less immediately.

@acuriousmind Hm... but I must raise $x^a$ to some power in order to get the order of this element. Therefore, $x^{ab} = x^n$ for some $b \in \mathbb{Z}$ so $n$ must be divisible by $a$, no?

So basically if you've been chatting to a girl for five minutes and she's not interested you need to move on.

@3075 It's the way it works. Sometimes you fancy people who don't fancy you and sometimes people will fancy you where you are the one not reciprocating. You have no claim on other people just because you like them. The pain of an unrequited crush wil fade in time, and indeed rather quickly when you don't see the other person anymore.

@Obliv No.

That's the way life is - blame God (whichever God you want).

::blames Odin::

odin didn't do anything wrong. It was probably aphrodite's fault

Whoever the God of computer nerds is, when we meet I have some harsh words for him!

I'm assuming it's a him because ... well ... computer nerds

@acuriousmind Well studies show that being with someone long enough makes them more attracted to you. I have no references for this I just heard it from somewhere.

also can you tell me why what I said isn't true?

@Obliv I think that's called "Stockholm syndrome" :P

@ACuriousMind oh you cynic!!! :-)))))))))))))

Hello my little duckypops

@JohnRennie Nerds go way back man

Unless you are a hundred and ten probably not

@Obliv It's just not true. Consider $\mathbb{Z}/6\mathbb{Z}$ and that $4$ is $1^4$ (if we write the addition as a multiplication), and 4 has order 3, while 1 has order 6. 6 is not divisible by 4.

@JohnRennie That's what I thought. But it took me 5 months to get with my girlfriend of 6 months.

What nerd things did you do in the 70's

Did you buy comic books

Play DnD

@Slereah tick

I wasn't big into comics meself

@Slereah DnD only really got going in the late 70s/early 80s and I'd grown out of it by then

Superhero comics aren't very big in France

@acuriousmind I agree. I can't believe you thought the proposition was false. amateur /sarcasm

did u read the science fiction

Or maybe it's only been 5 months

I can't count

Watch some terrible 70's boring sci fi movies

But still

@Obliv what?

@0celo7 You better learn to count before the anniversary comes around and catches you on the wrong foot!

What else did nerds do

@Slereah I've been reading SciFi for as long as I can remember.

The Star Trek, I guess

Wargames

I don't think speaking in Klingon was a thing in the 70's

Klingon was only invented for the Star Trek movies

More in the 80's

@MAFIA36790 I never did own a Commodore. Life was pretty tight in the 70s. There was a massive depression in the UK caused by the oil crisis (and UK industry being crap) and money was really tight. A Commodore was way too expensive.

The school had a 4K Commodoe Pet though.

Thank god Maggie cleaned up that mess

@Slereah there is now so much mythology around Thatcher that it's impossible for anyone to get a clear view these days. As someone who was 18 when Thatcher came to power, it genuinely felt as though society was crumbling back then. I mean, really scary.

@Danu You mean $H^n(T^m)$? Isn't that the normal cohomology group, for example obtained using de Rham? If you excise a point from $\mathbb R^2$, you get closed differential forms that are not exact. What do you mean by "sense only the behaviour at the point"?

@MAFIA36790 during my teenage years it was Heath then Wilson then Callahan then Thatcher.

@ACuriousMind We disagree when the relationship started.

Uh.

@MAFIA36790 yes, though that name was largely a PR stunt.

Yes, she was not actually made of iron

She did contain some iron

Mostly in her red cells

But for the most part it was carbon and hydrogen

and oxygen

@Slereah It worked for Stalin - for a while ...

This room is so weird some times.

Was it the Hitler

\o

@Slereah no! Don't you know any history?

Bismark!

Ah yes

Otto von

@JohnRennie *Bismarck

Not autobahn

I'm not very big on WWI era

Although apparently that is quite a hilarious bit of history

@ACuriousMind oops :: runs away in shame ::

Apparently WWI was basically the era where everyone got awesome war technology but basically nobody knew how to use it

It's actually horrible and depressing.

Can't edit spelling mistake in mobile?

I can't think of an iron president or an iron king

@Slereah I'm not sure "awesome" is the appropriate word :P

Gotta love mustard gas

I'm reading The Making of the Atomic Bomb by Rhodes.

Also, how did we end up here from discussing early nerdism (or is it nerditude?)?

Discussing youth -> Thatcher in his youth

It's mostly history of physics from 1900 through WWII. Excellent book.

You know

Very depressing though. War is awful.

I own a book from 1912

By Gustave Lebon

He claims very hard that he was the first man to have discovered that matter could lose mass

By an experiment measuring mass of decaying elements

@Bass the relative one.

I have no idea if his claim has any validity

@Slereah oh yes they did.

But he sounds very bitter about it

Where you compute homology relative everything but a point

In any case, if you're not familiar with things like the king exact sequence and such, then just what I said ;)

en.m.wikipedia.org/wiki/Bombing_of_Hamburg_in_World_War_II

NOT THE HAMBURGERS!

@Danu Yep :)

That is an example of WWII being horrible.

NSFL

The hilarious part of WWI are more like

Cavalry charges against tanks

@DanielSank Not Safe For L?????

The Austrian army not even knowing what grenades are

@JohnRennie "life", I'd wager

Just a lot of armies still having a lot of ridiculous uniforms

@MAFIA36790 Heavy!

My latest read on WWII was "My tank is fight"

It's a book on WWII Wunderwaffen

Including a neat chapter on the German atomic program

Not exclusively

There were actually two nuclear programs running in parallel

One ran by Heisenberg, in a more academic setting

And another by I forget whom, which was much more military oriented

Well, you know

Red Alert taught me

If the nazis didn't do it, the soviets would have!

@ACuriousMind well, maybe not

I think it depends on what you're counting

You know who else was a controversial writer?

Hitler.

My struggle

I suspect that a percentage of all humans are opportunists who will jump on an opportunity for personal gain when it presents itself. Then when it's too late they discover they are riding a tiger and daren't dismount.

@Bass I massively typo'd there. I meant long exact sequence, then just forget*

@JohnRennie so what was your first console, anyway

Or were you too old for video games

You old fuddy duddy

Consoles didn't come along until I was too old to be interested. I remember the first Space Invader games appearing in pubs though.

There were consoles in the 70's!

The Magnavox Odysee!

The Atari!

The Colicovision!

The Intellevision!

And a whole bunch of Pong consoles

At the time they seemed amazing. We'd spend hours (and lots of money) playing Space Invaders.

@Danu Never mind, I need to read the basics of singular and relative homology before understanding anything.

I think the Atari was right at the end of the 70s. I remember seeing one for the first time when I was at university.

Yeah most of them were kind of end of the 70's

Early 70's was mostly Pong consoles

Or very early cartridge consoles

The colicovision and the intellevision were kind of the consoles you got if you didn't get an atari

Atari was the cool one

I had an atari

It had the worst controller

So bloody stiff

what

No, it was just the family console, kinda

When I got to university the BBC Micro had just taken off and the university had been given a bunch of them by Acorn. We used to play games on them.

The Krasnikov tube has really fucked up light cones

And of course we used to disassemble the games to find out how they worked then hack them.

I once tried to disassemble the code of Monkey Island 2

Because I wanted to find a way to extract the PC speaker music from it

@MAFIA36790 We would actually print many thousand lines of 6502 assembler then go through them by hand - the things you do when you're young! :-)

I still have no idea how the music is played

Neeeerd

Me at least I went through glorious x86 code

@3075 you know I bet @JohnRennie hasn't asked anyone out in 20 years

@0celo7 you'd lose :-)

The last person he asked out was Margaret Thatcher

@DanielSank the Amazon description looks really interesting, but it's 1073 pages!!! I'm not sure i can concentrate for 1073 pages :-)

@Slereah she hit me with her handbag

@JohnRennie how long?

Also if you get that book you probably end up on government watchlists

@JohnRennie what book

CURIOUS ABOUT MAKING ATOM BOMBS ARE YOU

@0celo7 amazon.co.uk/dp/B00E2RG5GA

@Slereah :-)

I find it odd that there has been about 0 nuclear attacks since WWII

Not even a dirty bomb

Is a dirty bomb really that hard to make?

It's not like you have to care about the fission

No, but I find it odd

@Slereah the nuclear bombs are hoaxes

Well yes but see, even North Korea doesn't do it

They pretend to

Nuclear power is a hoax, honestly.

it's an old one

@MAFIA36790 it's not in the bible

I've seen it before

So why should I believe it

@0celo7 Nuclear power stations? They are real.

Everyone talked big in the 60's

Like that US plan to bomb the moon

To show the USSR they meant business

I know, I heard the song, too

@JohnRennie lol

Nuclear stuff was invented by the government to scare the people into thinking they have some great power

But only other governments care about it, tho

@Slereah "other governments"

It's all one big group, dude.

Possibly @0celo7

@Slereah No comment.

amazon.com/Global-Calculus-Graduate-Studies-Mathematics/dp/…

Very cool title

Do we not onebox Amazon links anymore?

apparently not
