Left a comment, though:

user116211

Hi @SF. . This is not the correct place to air your grievance. If you really think some injustice has been done, please feel free to ask it in Meta or come in our chatroom.

user116211

As that of closing, let me make it clear to you, my single close vote doesn't make your post get closed; there must be other four users who close-voted your question. So, this is not legitimate and rational to impose solely on me the closing. In fact, after checking I was the last one to vote in both the cases. Hmm.

user116211

Okay, he left such comments in ACM's nomination post also... this is ridiculous ;/

user116211

He is vehemently ranting now without any logical reason T__T

user228700

@JohnRennie: (Or anyone else too, really) I know that you did chemistry for awhile. I'm learning inorganic chemistry now and it is proving to be a nightmare, really. With regard to ionic equilibrium in particular, can you tell me why we bother to study it in the first place? At least then I may be less annoyed(and the desire to tear up my book will subside)...

user228700

9:27 AM

(I've posted this query in the CSE chat as well but the response is usually very low over there... :/)

John Rennie

I specialised in physical chemistry and specifically quantum chemistry. But, yes, I did three years of chemistry lectures (most of which I've forgotten). What in particular is giving you grief?

user228700

@JohnRennie Oh, I see. No, I don't need help with the concepts as such. I was wondering if you could tell me why in God's name we study these things in the first place!

user228700

And by "these things", I mean Ionic equilibrium.

John Rennie

For example, one of the ways in which I earn money is writing software for the nuclear industry to model the ionic compositions in reactor cooling systems. The cooling water contains a witches brew of various ions and has a range of pHs. If you get the composition wrong it corrodes the pipes and BANG!

user228700

@JohnRennie Yikes. Interesting.

John Rennie

9:32 AM

So understanding the ionic equilibria involved is fairly important.

But I'd be surprised if at undergraduate level you had to anything nearly as complex as this. What sorts of problems are you being presented with that are raising your ire?

user228700

@JohnRennie Hm, OK. Thanks. I have about 170 pages to get through.

user228700

Oh, there's loads of crap!

user228700

Just flipping through the pages is giving me a headache :-(

John Rennie

The equilibria are just regular equilibria, I don't think there's anything special about ions. You just get something like $K = [A^+][B^-]/[AB]$.

user228700

@JohnRennie Yeah, but there are some other concepts involved. Buffer solution, levelling/differentiating effect of solvent, Ostwald's dilution law, pH of ALL KINDS OF MIXTURES, salt hydrolysis, solubility, solubility product, indicators, titrations, name a few.

user116211

9:38 AM

@JohnRennie, Could you tell me what to do? He is constantly alleging me ;((

John Rennie

@MAFIA36790 There isn't a lot you can do. If it gets personal complain to the mods, but if all he's saying is that you voted to close his posts then, well, you did.

user116211

@JohnRennie Surely, I did; I'm not disagreeing with this; but he is blaming me for my closing his post; and also attacking the nominees especially ACM there. this is bothering ;/

John Rennie

@DavidZ @dmckee @Qmechanic the comments to Alfred's nomination post have gone well off topic and could usefully be pruned.

user228700

@JohnRennie: OK, I'm gonna go try my best. 170 pages. Sigh.

John Rennie

@MAFIA36790 SF. appears to have a chip on his shoulder. He's made rude comments to several of the posts. Just ignore him - there is simply no point in engaging with someone who is only interested in their own point of view and will not listen to yours.

@KaumudiHarikumar yes, there are lots of applications but the basic principles behind them all are the same. Is there really that much to learn?

user228700

9:45 AM

@JohnRennie Yes. Like I said, 170 pages.

user116211

@JohnRennie sure.

John Rennie

Incidentally I'm happy to answer questions on chemistry, though I'm likely to struggle with anything outside physical chemistry.

user228700

@JohnRennie And ionic equilibrium...doesn't come under the realms of physical Chem.?

John Rennie

@KaumudiHarikumar I'd say that was physical chemistry.

user228700

@JohnRennie I also need to finish these 170 pages in about 4-5 days. Yeah, I'm screwed.

user228700

9:47 AM

@JohnRennie OK...I will ask you if I face major problems then. Thanks :-)

John Rennie

Incidentally I am a member of the Chemistry SE though I rarely post there. You should be able to ping me from the chemistry chat room. I think you have to visit the room at least every two days to be pingable, but if I'm not pingable there just ping me here.

user228700

@JohnRennie OK, will do :-)

user228700

Thanks!

user128101

10:02 AM

@MAFIA36790, @JohnRennie, it was not a hate message, it is the plain truth, you are, after ACM one of the meanest reviewrs around. And it is a shame, since you are a student who just a little over a year ago was whining that your question had been unjustly closed, and writing posts fulls of all sorts of typos and blunders. Y

user128101

ou should be compassionate and understanding of students who are just what you were short ago. Your average of close and leave close is appalling: take a look of how many posts you VTC, john voted to leave open and draw due consequences.

The Moderator Election page started accumulating a lot of noise. Perhaps those comments need to be moved or removed, since they offer nothing related to the discussion. I won't link to specific users, but i think it's very obvious.

Swapnil Das

Can I cast a vote in the election?

( Just curious )

Newmann

@david-z Dear Mr. Zaslavsky, I hope that everything is clear now for you in questions physics.stackexchange.com/questions/282261/… . Also in question physics.stackexchange.com/questions/281726/…. An user named DelCrosB mussed up the latter question just because he didn't like the term "massive photon".

@Qmechanic Dear Doctor, the question physics.stackexchange.com/questions/282261/…, has been put [On Hold] for unclear reason. However, I've edited the question as much as possible. I appreciate your help for this matter. Thanks a lot.

Swapnil Das

How can I cast a vote in the election? I have a personal fav.

Danu

@SwapnilDas It's too early, you can do it next week (if you have 150 rep), here: physics.stackexchange.com/election/3

Swapnil Das

@anna-v Dear Prof. Anna, it would be fine and kind of you if you also take a look at this question: physics.stackexchange.com/questions/282261/… . Your answer is highly appreciated. Thanks.

user116211

@Newmann She doesn't come here.

Danu

11:54 AM

@SwapnilDas I wouldn't really call myself either. I'm studying math.

Jim

12:13 PM

so I just accidentally joined a large steel sphere to an extremely strong permanent magnet and I'm having trouble separating them. Thoughts?

user228700

@JohnRennie: Chemistry was pissing me off so I switched to math for a bit and I already have a small question. I asked at the MSE chat for help but they didn't understand :/

Hello everyone :-) Can anybody provide me the exact definition of an "algebraic function"? is how my textbook defines it:

ACuriousMind

> I retract and apologize for my earlier comment saying that you were creating a hostile atmosphere. I confused you with 'CuriousOne'.

Oh dear. Is this going to happen a lot?

Jim

@ACuriousMind yes

Swapnil Das

@ACuriousMind Hi! I'm your PSE fan :)

Jim

12:16 PM

^ aren't we all?

ACuriousMind

@Jim Well, what am I supposed to do about it? Add a disclaimer "I'm not CuriousOne" to my nomination?

That seems kinda weird

Jim

@ACuriousMind You're new campaign platform

"Vote for me, I'm not CuriousOne"

Swapnil Das

I'm a fan of your answers

Even more because you are a theorist

Balarka Sen

"I'm also an orc, not a troll"

ACuriousMind

@SwapnilDas Well, you shouldn't vote for me merely because you like my answers. I'd still write my answers if I'm not elected. Although I might not if one of the joke candidates gets elected :P

user228700

12:19 PM

Jim

@ACuriousMind joke candidates? I should run as a joke

Swapnil Das

@ACuriousMind I vote you for a plenty of reasons

Jim

Although, if I'm actually elected, I'd lose all faith in humanity

user116211

@Jim There are indeed many there ;P

ACuriousMind

@Jim I'll not get specific but have you looked at the nomination page?

Jim

12:21 PM

@ACuriousMind not since it was posted

user116211

@Jim Please go on and check!

Swapnil Das

@ACuriousMind 1. You are a theorist. 2.You know string theory and good math. 3. You are write neat answers :)

user228700

Hey, I've got a question. Why is this network named "Stack exchange"..?

user128101

@Jim, "...so I just accidentally joined a large steel sphere to an extremely strong permanent magnet and I'm having trouble separating them. Thoughts?", try to slide it off instead of trying to pull it apart. It'll work

ACuriousMind

@SwapnilDas I'm not exactly a string theorist, and again, all those things might make me a good user, but I don't see why they would make me a good moderator.

Jim

12:26 PM

@user104372 Already tried that. The thing is a broad horseshoe magnet. I can't bring the sphere even to the edge of the face plate because the field keeps it centred

Swapnil Das

@ACuriousMind I don't carry political reasons, I'm at last a tenth grader :P

user116211

@ACuriousMind: Man, do spend the same amount of time here and the site even after you become a mod ;)

Swapnil Das

Yeah.

user228700

@SwapnilDas Moderators have enormous responsibilities on this website, apart from answering questions expertly and being great at what they do(and this I learned a few weeks ago) It is a tough task and has nothing to do with "political reasons", to my knowledge.

user128101

@Jim, then do like Archimedes and you can move the earth

John Rennie

12:29 PM

@KaumudiHarikumar it started out as a site for programmers called the Stack Overflow - stack overflow is a term in computer nerd speak. When it became obvious the site was a big success they broadened it to other areas and the name Stack Overflow was no longer suitable.

Jim

@user104372 Tried that too

Swapnil Das

@KaumudiHarikumar "Political" here was just a poetic license :P

ACuriousMind

@MAFIA36790 I don't expect that to change, although might need to refrain a bit more from talking about specific users.

Jim

broke several levers and the others were magnetic

user128101

@Jim, poor sod, Archimedes!

John Rennie

12:30 PM

I suppose they chose the name Stack Exchange because the site is aimed at the exchange of information.

Swapnil Das

Or "Stack"

user116211

@ACuriousMind You made my day!!

ACuriousMind

Well, that was easy

user228700

@JohnRennie Oh, I see!

Jim

Hmmm, of all the nominees, ACuriousMind and myself are the top two scores

I know one of us will likely get it

ACuriousMind

12:35 PM

You do realize there are two free positions, right?

Also, why couldn't you have made a serious nomination :(

user116211

@Jim, You should have mentioned you are the King of all Jims ;)

ACuriousMind

btw, rare sighting of Kyle Kanos in the nomination comments

Jim

@ACuriousMind I am aware that I don't have the time to make a serious commitment to moderation. As such, I cannot in good conscience put myself up for serious nomination

user228700

@JohnRennie: Any thoughts about that math question..?

user116211

@ACuriousMind He indeed visits the site on and off.

Jim

12:37 PM

I mean, if elected, I'd do my absolute best, but it's a responsibility I don't think I could do justice to

user116211

@Jim But you ran for a nomination...

Jim

@MAFIA36790 And would you vote for that platform?

user116211

@Jim Hmm, I want your profile more informative first.

Jim

@MAFIA36790 say what? What about my profile is not informative?

user116211

@Jim Why would one choose you? What would you do after being a mod? That's what I want to be mentioned explicitly.

John Duffield

12:41 PM

@Jim : build a bonfire around it.

user116211

Although @Jim, I really find your profile interesting to read ;)

Swapnil Das

@Jim

user116211

Also, @jim, have you answered in the Questionnaire? I'm waiting for it.

Swapnil Das

You are a cosmologist! Cool.

Jim

@MAFIA36790 Ah, well my nomination wasn't serious. If I'm still elected: 1) I'd lose all faith in humanity and 2) I'd probably become even more impartial than I already am (I know, how's that possible) and I'd stick to mostly improving posts, answering in meta, and resolving flags/disputes. At least until I got the hang of all the new tools I could use

John Duffield

12:45 PM

@ACuriousMind : joke candidates? This is not the sort of attitude one expects from a would-be moderator.

@DavidZ : see above.

ACuriousMind

@JohnDuffield There's a one-line nomination with a link to a picture of Dr. Evil there. Would you call that serious?

3

Danu

@JohnDuffield Lol, classic politician mudslinging :P

Jim

@ACuriousMind Yes?

Dr. Evil would make a great moderator

He has sharks with laser beams attached to their heads. Moderation accomplished

John Duffield

@ACuriousMind : you said joke candidates. Plural.

Danu

@JohnDuffield Do you want him to say you're a joke candidate? Because that seems to be what you're aiming for.

John Duffield

12:49 PM

So Jim, what's all this about magnets? I know about magnets. Amazingly, you can make a magnet by merely rotating a piece of iron.

Alex

@ACuriousMind The position eigenstates are not strictly speaking, quantum states, since they are not square integrable. What about the eigenstates of spin, for say $\hat{S}_z$, are they quantum states?Also, we know that $\langle x|p \rangle = \frac{1}{\sqrt{2 \pi \hbar}}e^{\frac{i p x}{\hbar}}$ but what are the transformation functions $\langle x| s_z \rangle$ and $\langle P| s_z \rangle$?

ACuriousMind

Well, there are at least two other nominations which are obviously intended to be funny. I'm not sold on how serious the candidates themselves are.

0celo7

ok @ACuriousMind my analysis homework is over the top hard this time

ACuriousMind

@Alex Your latter objects don't exist. The spin states don't exist in the same space as the position wavefunctions - if you want to have a state of a particle that freely moves and has spin, you need to take the position space $L^2(\mathbb{R})$ and tensor it with the spin space $\mathbb{C}^2$, so you have objects like $\lvert x\rangle\otimes \lvert s_z\rangle$:

0celo7

> Let $(S,d)$ be a metric space. Then \[\tilde d(p,q)=\frac{d(p,q)}{1+d(p,q)}\]
is also a metric on $S$.

How on earth do you get the triangle inequality from this

ACuriousMind

12:52 PM

With skill and grace

Sorry, not in the mood for math

user116211

@Jim That sounds much better; you should mention clearly why you think you are competent for the job and what experiences you have that made you consider yourself a good mod; you should mention this what you have written here there at your nomination bio (except point 1 ;P).

0celo7

@BalarkaSen that's seriously unhelpful

user116211

@0celo7 I think it's in the exercise of Kreyszig.

0celo7

what?

Balarka Sen

I know it is.

There, I deleted it.

John Duffield

12:55 PM

@Danu : that's not very nice, now is it?

Especially since I know how a magnet works.

Danu

Alex

@ACuriousMind Are you saying $\mathbb{C}^2$ because you are assuming that I am taking particles with $s = \frac{1}{2}$ spin?

ACuriousMind

@Alex Yes, for spin $s$ it's $\mathbb{C}^{2s+1}$, of course.

Danu

@ACuriousMind Also, dude

0celo7

Dude bro

Danu

1:00 PM

Did you realize that the map between states ($S^3$) and expectation values of the ''spin vector'' (on $S^2$) is the Hopf fibration?

ACuriousMind

@Danu Yes

Danu

@ACuriousMind That's so excellent

10/10 geometry

Slereah

neat

Jim

@MAFIA36790 I would except that I fail on one of the most important issues. I don't have more than a couple hours a day to offer to moderating the site. But for that, I'd put forth a serious nomination platform. But I'll compromise with you and answer the questionnaire in a serious way

0celo7

Isn't the hood do ration topology

lol that autocorrect

user116211

1:02 PM

@Jim That's great :)

Danu

@0celo7 how do I language :P

Ah, Hopf fibration

I classify it under geometry because connections and curvature play a big role.

Jim

@JohnDuffield I have a very strong horseshoe magnet to which a steel sphere is currently stuck. I want to remove the sphere. Nothing I've tried has worked. I tried sliding it off and using a lever to slide it off. Nothing.

user116211

@Jim Use TNT.

Balarka Sen

Jim

@MAFIA36790 Of course, why didn't I think of that? TNT is the answer to all unsticking problems

Danu

If ACM is elected it will be great for the site.

ACuriousMind

1:08 PM

@user104372 How? I've got several comments saying that but no one ever actually gets specific about what they fear I'll do.

Danu

@Jim The only solution to all real problems

user228700

@ACuriousMind Exactly what I was thinking :/ @user104372: Why do u think so?

user128101

@ACuriousMind. It's so nice to be specific.

user116211

He would be elected democratically and by no foul means.

Jim

@user104372 I do not desire the power of authority nor the responsibility that comes with it. I have always had a certain distaste for authority. If asked to step into the role, I would do my best for the community and perform the role as adequately I could, but never would I elect to do so if I felt I could cede that task to someone similarly or better qualified

user128101

1:11 PM

@ACuriousMind, if you wish me to be even more specific, I can, but it'll hurt your inflated ego

John Duffield

@Jim : put it in a vice and hit it with a sledgehammer. Or trash the magnet by burning it in a fire. Or get another horseshoe magnet. Is this for real or is it a quiz?

Danu

@user104372 Go go go go for it!

ACuriousMind

@user104372 Yes, I do wish you to be more specific how I would be a "disaster" for the site.

Jim

@JohnDuffield For real

what is this madness

Danu

@ACuriousMind I'm on a roll!

I AM!

WHEN IS THIS GOING TO END

John Duffield

@user104372 : Your magnet is in the vice. Hit that wedge hard enough and you won't need anybody to catch the steel sphere. Mind you, you might break your magnet.

Balarka Sen

If moderator elections in physics.stackexchange are such a big pain in the neck with all the mutual slanderings, I can imagine what happens at "da real election".

Slereah

Make Stack Exchange great again

John Duffield

In fact, you probably don't need a wedge. Put the magnet in the vice, and hit the steel ball like you're playing golf.

Balarka Sen

Yup.

John Duffield

1:25 PM

@HDE226868 : that NY times article is secondhand stuff from a biased newspaper trying to tell you what to think. Give me a concrete example of Trump lying about 5-10 important campaign points on a daily basis for the last month. When you struggle to do so, maybe you'll start thinking for yourself.

@Slereah, Even Bourbaki writes in its preface that no mathematical perquisites are necessary; really seems to be ~~not~~ true.

Oh Bourbaki doesn't require any math

He defines all the math

@Slereah Nay, I do get what he writes but it takes so much time to comprehend why they are doing so.

user116211

I mean they lack motivation.

they do it to write shorter formulas

Is that real math?

ACuriousMind

No, its just fantasy

This is Foundation of math!!

2004 Classification of finite simple groups. The proof of this is spread out over hundreds of journal articles which makes it hard to estimate its total length, which is probably around 10000 to 20000 pages.

Nuclear physics TA took off 7 points for rounding too much

I despise this person

@0celo7 WTH ;/

2000 Almgren's regularity theorem Almgren's proof was 955 pages long.

Ironically the wikipedia article on it is two lines long

user116211

@Slereah: Did you read Mathias' paper on Bourbaki?

Slereah

I did not

0celo7

@Slereah what is the classification in the end

Danu

1:41 PM

@0celo7 Very large, hahaha

0celo7

Is it like a bajillion pages?

Slereah

Probably

I tried to look up the generators of E8 once

List of finite simple groups

In mathematics, the classification of finite simple groups states that every finite simple group is cyclic, or alternating, or in one of 16 families of groups of Lie type, or one of 26 sporadic groups. The list below gives all finite simple groups, together with their order, the size of the Schur multiplier, the size of the outer automorphism group, usually some small representations, and lists of all duplicates. == Summary == The following table is a complete list of the 18 families of finite simple groups and the 26 sporadic simple groups, along with their orders. Any non-simple members of each...

Slereah

Then I saw that I had to download files of several gigabytes

ACuriousMind

@Slereah That's not a finite group

Slereah

1:41 PM

And I thought maybe not

0celo7

That's not finite.

Slereah

No, but it is another thing that is big

user116211

@Slereah, check this: dpmms.cam.ac.uk/~ardm/inefff.pdf

@Danu wow

Balarka Sen

@Slereah I suppose that any proof of the statement that the shortest proof has at least a googolplex symbols has at least a googolplex symbols?

Slereah

1:43 PM

no math now

cooking some chicken

Danu

@0celo7 Not so bad, eh?

0celo7

@Danu a trivial exercise.

Danu

If I ever become a prof and teach some algebra 101 course

I will make the first exercise on the first sheet: Classify all finite simple groups.

0celo7

Your office hours will be flooded

Danu

No office hours in Germany

The TA's deal with that ;D

0celo7

1:50 PM

What kind of crap is that

I would like a TA for analysis. I'm seriously stuck but I don't want my prof (advisor) to know that

I have three exams this week and four problem sets and I can't waste 4 hours thinking about those two problems

Jim

There, I posted my answers to the questionnaire

ACuriousMind

@Danu Well, the professors do have office hours, but they'll kick you out if you start talking about exercises :D

Q: Can we try to cut the vitriol during this election?

Well, we're a day into the nomination phase of Physics Stack Exchange's third election. We already have 8 candidates for the two positions available, and no doubt we'll get plenty more. A pattern has begun to emerge, and it's not hard to see where it's leading. In both nominations and comments, ...

A: 2016 Moderator Election Q&A - Questionnaire

How would you deal with a user who produced a steady stream of answers with mixed or negative scores, but still manages to get thousands of rep (because upvotes count much more than downvotes)? That really depends on the specifics of the situation? Is the user trying their best? Are th...

user116211

@Jim I like that especially the the 3rd , 5th and 9th point.

Bernard Meurer

2:13 PM

@0celo7 You around?

@ACuriousMind Or you

ACuriousMind

Intermittently

Bernard Meurer

@ACuriousMind Are you free later tonight?

I need help understanding convergence

The definition is very nebulous to me right now

user116211

@BernardMeurer What thing is bothering you?

Bernard Meurer

@MAFIA36790 I just don't understand it

0celo7

I like how questio #1 is to sniff out who would ban JD

user116211

2:16 PM

ohh.

Bernard Meurer

@0celo7 Skype 2night?

Plox

ACuriousMind

@BernardMeurer Can't promise anything, packing/sorting my things will take a while

Bernard Meurer

@ACuriousMind That's alright

0celo7

No

I have analysis homework too

And I don't understand it either

user116211

Why not try those MIT OpenCourseWare?

Jim

2:18 PM

@MAFIA36790 I thought people would appreciate the 8th point most

user116211

They have some good lectures on Infinite Series, Convergence, Series etcetera @bernard.

user116211

@Jim I loved that brief Jedi analogy.

John Rennie

@Jim Heat it to above the Curie point?

Balarka Sen

I suggested that!

John Rennie

@user104372 Sorry to disillusion you but ACuriousMind is my preferred candidate by a long way.

Danu

@ACuriousMind where is the data query that plots answer score graphs for a particular user?

@JohnRennie By the way, do you plan on running, yourself?

John Rennie

Caught in a landslide,
No escape from reality.

Bass

@Danu This one? data.stackexchange.com/physics/query/396403/…

ACuriousMind

@JohnRennie Thanks, was waiting for that :)

user116211

@BalarkaSen I suggested the best ~~dangerous~~ thing that would guarantee a positive result ;/

Balarka Sen

2:41 PM

How about using an atom bomb instead?

John Rennie

@Danu I honestly don't think I'd be a good moderator because my judgement tends to be lacking. I would stand if I felt there weren't any nominees whose views reflected mine, but that isn't the case.

@ACuriousMind we both agree to ban all questions on thermodynamics, yes? On the grounds that the subject exists only for the setting of fiendish homework problems and only engineers use it in real life :-)

user116211

@BalarkaSen Damn, we need to survive ;/

0celo7

Same with EM really.

@MAFIA36790 @BalarkaSen please don't get nuked

Q: Could the mystery of “Dark Energy” be demystified by general relativistic Massive Electrodynamics (as a new approach)?

In one of the relevant recent papers published in Physical Review D physicists claimed that massive electrodynamics could provide an explanation of dark energy. Here is the paper: Title: "Massive photon and dark energy", https://journals.aps.org/prd/abstract/10.1103/PhysRevD.93.083012 Preprint...

This one bypassed the automatic review process and I'd prefer to have the community take a look at it before I do anything unilaterally

Secret

2:48 PM

how does this bypass the automatic review?

Jim

@JohnRennie I'd like to avoid destroying it

David Z

@Secret it got edited again while a review was pending, so the review got invalidated.

Not really "bypassed" I guess

John Rennie

In seriousness, can you upload a picture? It's hard to tell from the description what your problematic magnet looks like.

Secret

ok, that's sounds normal

Danu

@JohnRennie Alright.

We just need a second "great" candidate...

Balarka Sen

2:52 PM

How about connecting the magnet to an alternating current source? I think that'd lower the intensity of the field.

user116211

@danu, what about you? You have the experience of being a mod.

Danu

@MAFIA36790 If no one else I really know would be great steps up until 2 or so days before the end of the nomination period, I'll think about it. It's probably not going to happen, though.

Algebraic function

In mathematics, an algebraic function is a function that can be defined as the root of a polynomial equation. Quite often algebraic functions can be expressed using a finite number of terms, involving only the algebraic operations addition, subtraction, multiplication, division, and raising to a fractional power. Common examples of such functions are: f ( x ) = 1 / x {\displaystyle f(x)=1/x} f ( x ) = ...

user116211

@Danu okay.

John Rennie

@BernardMeurer: since you're here, is a BCM970012 hardware graphics processor any of use to you? It might be faster than the Optimus for number crunching.

I have one that I bought because we were going to support it in XBMC then never did.
