@ACuriousMind oh that's definitely not right

12:46 AM
@ACuriousMind ok I have found the new topology
this is the right one now
I've adapted the topology to both Stampacchia iteration and the maximum principle

@HDE226868 the dude’s name is Daniel

4:28 AM
@RyanUnger Does his last name start with a W?
I do know a Daniel who may be at Princeton this summer.

@HDE226868 Yes

@RyanUnger I know some of these words :P

11:25 AM
@ACuriousMind is it Stampacchia

You know me too well

whatever happened to "Blue"?

@skullpatrol he was in a superposition of being a physicist and a quantum computing guy, but he collapsed..

i always thought he'd stay around to help out the JEEers
the collapse even changed his username @JohnRennie

A philosopher talking about spacetime so discording that no temporal order can be defined for any point

1:37 PM
@skullpatrol what's his new username?
@JohnRennie what do you mean by "he collapsed"??

@Abcd It's a pun on the notion of quantum state collapse
John means that ex-Blue decided for one of the two things, i.e. quantum computing, not physics

2:07 PM
@ACuriousMind And his new username is?
Nevermind found it

@RyanUnger I think I know who you're talking about. We've had a couple physics and math classes together.

@Abcd silly joke:
In quantum mechanics, wave function collapse is said to occur when a wave function—initially in a superposition of several eigenstates—appears to reduce to a single eigenstate due to interaction with the external world; this is called an "observation". It is the essence of measurement in quantum mechanics and connects the wave function with classical observables like position and momentum. Collapse is one of two processes by which quantum systems evolve in time; the other is continuous evolution via the Schrödinger equation. However, in this role, collapse is merely a black box for thermodynamically...

@HDE226868 he is, for the lack of a better term, a distinctive person

@RyanUnger Then I definitely know who you're talking about. He is distinctive indeed.

@Danu some of us have to generate the GDP to pay for you idle layabouts to have a good time :-)

2:17 PM
@JohnRennie you're a GDP person too?

@RyanUnger yes, I got a job when I finished my PhD. I worked as an industrial colloid scientist. And to be fair it was good fun.
But then I was never going to revolutionise the scientific world so I was no great loss to it.

no I know that
I mean you're a big suporter of GDP
you know I'm something of a GPD supporter myself

Productivity $\propto$ standard of living.

Given that I would like to enjoy a good standard of living that means productivity is important.

2:22 PM
mathematicians are indeed layabouts

@RyanUnger for the record I fully support my taxes being used to fund research. In science and maths.

a mathematician is about as much money as a missile

@RyanUnger I'd have thought a missile cost a lot more. Don't cruise missiles cost tens of millions each?

oh not a cruise missile

Unless mathematicians are paid a lot more than I think :-)

2:25 PM
let's say more of a rocket

Maths vs killing people. It got to be a win for maths.

some math at least

The best people to decide what maths should be studied are the mathematicians.
i.e. not me.

@JohnRennie Thank you, dear plebs

@ACuriousMind it's curious that I'm doing GA when I don't like contradiction arguments
around half of the proofs in the field are by compactness/contradiction or the maximum principle

4:33 PM
@ACuriousMind How to post a citation in ask question section?

@knzhou hey there

2 hours later…
6:34 PM
@Student404Mus There's no inbuilt "citation" functionality
You have to manually give the reference however you like
@RyanUnger It would seem more like a love/hate relationship then, no? ;)

@ACuriousMind I want to believe that one can do math without contradiction
but I don't even think one can work with sequences without it

You can do a lot of math without contradition
But it's not particularly pleasant

can you prove $\lim_{x\to a}f(x)=f(a)$ iff $\lim_{i\to\infty}f(x_i)=f(a)$ without using contradiction

No idea
Look up intuitionist analysis I guess
You can do a lot of math without the weirder axioms but you basically end up with Peano's axioms
You basically have to give up the real numbers if you can't abide by weird shit
Real numbers are the worst

6:54 PM
the dude abides by the real numbers

Also of course you have to be ultrafinitist bc obviously very large numbers aren't real
I have never seen any $2^{99999}$ things
Heh

@ACuriousMind Thank you for replying.

Based on the article given by [J. L. Ball, I. Fuentes-Schuller, and F. P. Schuller, Phys. Lett. A 359, 550 (2006)] had used the following expression of von-Neumann entropy S = - \operatorname { Tr } \left( \varrho \log _ { 2 } \varrho \right) = \log _ { 2 } \left( \frac { \left...

How could Entanglement concentration not contradict the axiom LOCC can only decrease entanglement?

I posted the question physics.stackexchange.com/questions/486272/… yesterday, but I am still left totally unsure about the answer. Basically, a microwave oven vs a gamma rays / x-rays oven. what are the differences?

Does the golden ratio have any actual use in mathematics

it's shiney

@SirCumference What in mathematics has an actual use?

@Avantgarde Rephrased: is it noteworthy or significant enough to warrant the popularity it gets (mostly among numerologists)

11:08 PM
@SirCumference Nothing warrants the attention it gets by numerologists - almost by definition, since if the topic warranted actual scientific attention, the people interested in it would be mathematicians, not "numerologists" :P

11:30 PM
@ACuriousMind Well numerologists are an example, but practically everyone with a slight interest in math has heard of it. I'm wondering if it actually has enough importance to explain that

I don’t think any specific numbers are interesting

heyyy alll!

@RyanUnger u wrong

Hi everybody

11:45 PM
@DanielSank u suck

Ban him.
That's against the be-nice policy.

lol
There is no policy
The mods are asleep

All of them?

Apparently so.

I thought they took turns or something

11:47 PM
Bye, everybody.

They ded

Will you be mad if I flag that

I’m going to be in SF on the 19th of next month
Are you there?

Probably!
Whatcha doing here?
