@Danu planet hunters? zooniverse!!
00:14
@TanMath Right, that.
@Danu coolest thing ever... I have participated in many zooniverse projects...
@vzn "Equally stressful is the fact that PhD students face “uncertainty about the future, such as funding for research" - Not to dispute that the stress is real but only to point out that uncertainty about the future and/or about funding isn't unique to to PhD students.
@dmckee hasn't this question been asked before?
wait, didn't know @MarkMitchison was here...
I had a really nice one of eclipsing binaries just now:
00:20
@Danu ur mum eclipses any binaries
Really clear :) The brightness variation is so huge, too!
@Danu oh... did you post this on discussion?
@TanMath I commented on it... Should I be doing more?
@Danu btw, how can you be sure it is an ecplising binary and not another planet?
@Danu no.. that is fine
@Danu Niiiiiiiice!
00:27
@TanMath Look at the brightness variation.
It's 30% almost
Most of the time it's like... <1%
so I figured...
I'm not actually sure, obviously :P
@Danu looks like the consensus is ecplising binary...
Yea, that too.
it should be called the Danu binary!
Anyways, it's 1:30 AM now so I gotta head to bed.
it seems you were the fiest to recognize it...
00:30
@TanMath Don't think so.
@Danu where do you live? gud night!
@TanMath Munich.
I was the most recent to note it (oldest comment is 11 days old).
@Danu oh.. I thought the beginning was oldest...
Good night!
00:54
whoa apparently there is a closed form expansion for the metric in Riemann normal coordinates
01:24
hey hey
obe
obe
01:38
hey
Fallout 4 has a nudity mod
Woot
yeeeeessssss
28 pages of mods already
lol nail trimming mod for Dogmeat

A: How to explain what an electron is to someone new to physics?

John Duffield How to explain what an electron is to someone new to physics? I think you can come up with an easy-reading explanation that's physically correct. There's plenty of clues in the literature if you're willing to play detective. For example see pair production. We quite literally make an electr...

How did I miss this
> 4) The electron is a 511keV electromagnetic wave going round and round in a knot-like stable spherical spin-½ spinor configuration, such that the field-variation propagating at c now looks like an all-round standing field. Standing wave, standing field. In its simplest guise within an atom we call it an S-orbital, which is depicted below:
My smile is out of this world
"your pencil doesn't fall down in FLRW so there is no gravity"
:D
@WhatRoughBeast : I answered the OPs question step by step, sentence by sentence. Which is a darn sight more than you've done, naysayer. — John Duffield Sep 21 at 7:24
XD
03:07
@ACuriousMind Are ghouls immortal?
@0celo7 Almost, yes. It's one of the points which makes some of the intelligent ones believe they are an evolutionary step forward.
@ACuriousMind So what are the super mutants
Are they accidents?
Were they once humans?
Where are the female super mutants
@0celo7 Results of different FEV virus strands, with intelligence, strength and other precise characteristics depending on the strands. The super mutants in Nevada are not the same as those in Washington
In the end, they're the all the result of VaultTec biological experiments
I think there's some handwaving about the virus being lethal to women, but I'm not sure it's ever really addressed.
aaaaand Fallout crashed my computer
beautiful
@ACuriousMind virus?
@0celo7 Well, I guess I made the old mistake of doubling the abbreviation. FEV means Forced Evolutionary Virus, there are some quests in F3 and NV which explore this, I think - you even get a super mutant companion in one of those which is unusually intelligent and non-aggressive because he's been infected with a variant developed in the vault where the quest takes place, I think
And no, don't ask me how a virus is supposed to do what it apparently does :P
03:16
The Super Mutants seem a bit fragile in F4
They're all like "Grrr, I'm so tough"
"I am so manly"
"I don't think hunky blokes are sexy at all"
Overcompensating a bit
Fragile in their masculinity
Strong is a sweetheart down under all that muscle and green skin
@ACuriousMind you get something similar in F4
want me to tell you?
03:41
@0celo7 Nope
@ACuriousMind so you do plan to play it
@Slereah what do I do in Covenant
tbh I was expecting some ghoul infested place with a nuke in the middle
@0celo7 Eventually I'm sure I will
pleasantly surprised
03:56
@0celo7 There is a Mystery to solve
solving.
@0celo7 Spank any naughty nuns who left the grail beacon lit?
If you can handle the peril, of course.
Taking no bets on this one.
@dmckee: How often do you get linked to this xkcd? ;)
@ACuriousMind I think that's the first time I've seen it since the week I trawled the archive. But then I've only recently starting thinking of Monty Python bits every day after a years long hiatus.
Man, the old ones look really strange
@dmckee Rewatched something or random relapse?
04:05
Perhaps I just need to figure out what the kids think is funny this decade.
@Slereah Is it normal that some computer logs just abruptly end in the middle of sentences
I feel like there should be some way to get to the next page
@ACuriousMind Random. Couldn't say what triggered it. But I desperately want to find an excuse to quote Brian: You are all individuals. Crowd (unison): We are all individuals. Lone voice: I'm not. at someone.
I'm reading the PC logs in the police station and they just get cut off
@dmckee Now I want to go and watch Life of Brian.
Thanks for that.
My English teacher used to watch that with us every week before the summer holidays
Better than The Meaning of Life and monsieur's bucket.
04:13
I have far greater problems getting that song out of my head
oh, lol
now y'all get a taste of what it's like to be a moderator
What the...
Time to clean up the socks, mods!
And I've been wanting to get back to You Can Study Buzzed, my dear old alma mater, too.
Why was that removed?
@0celo7 I'm guessing because the sockpuppet account that posted that was nuked :P
04:22
Daniel is trying to protect his secret identities.
Or that^
lol
@0celo7 even if the posting account were still around, though, that's not a constructive contribution on meta. Right?
Legitimate criticism of a moderator's actions is fair game, although generally it should be directed at the SE team. But this is just crazy.
I kind of want to leave the onebox up for your amusement though :-P
::tries to remember seeing @DanielSank and @dmckee online at the same time::
Hmmmmm...
@dmckee So I hear you are evil
@Slereah uh
do I let her live
or go with Dan
04:29
Let who live
Not evil. Never evil. Mad.
the doc
Oh
I killed her
But if you kill her
You're not welcome in covenant anymore
I had to murder everyone there
can you rebuild it?
Fourier transform of a cat. Look what you have started, @ACuriousMind.
04:31
Rebuild what
The town?
I'm trawling the archive again.
yeah
Not that I know
@dmckee Bwhahahahahaha!
what happens if you kill dan
04:31
everyone is still dead
Dunno
Maybe you're not evil, but I seem to be :)
is it a settlement in your menu?
according to google-fu, you should kill Dan
turns out the gril really is a you know what
o
Welp, too late for me!
Also no matter since I will destroy the institute eventually
04:34
SPOILERS
LALALALALALALA
It's not really a spoiler man
There's an Evil Organisation
And you are in a video game
Of course you're gonna destroy it
@dmckee that needs to become an expression. I really want to say "[...] is like taking the Fourier transform of a cat"
2
I wonder if the Mathematica SE has a cat graph
apparently not
what
@0celo7 Look, I think I need to update my style. What sorts of things are funny this decade?
04:43
@dmckee me
@Slereah spoilers
@0celo7 Obviously true, but not useful for cultural references outside the hbar.
user54412
@Danu I've never done it myself. But I happen to be, ya know, an astronomer. Also, nice eclipsing binary.
@ACuriousMind Eh?
@DanielSank I'm reliably informed that we can't both be online at once. So who should leave?
@DanielSank Look a bit upthread, apparently you are dmckee and also a bunch of other users
04:44
@PhysicsMeta WHAT THE f$#*&?
And evil. And ignorant of physics, too.
user54412
Given his latest behavior, I suspect @dmckee is also Randall Munroe, promoting his comic.
@ChrisWhite Nawh. My drawing still isn;t up to that level of sophistication.
Seriously.
Hey, @dmckee, can you use your modpowers to get a screenshot of that post and email it to me. What an honor to be targeted online!
His stick figures are sooooo much better than mine.
04:46
@DanielSank Just 900 sweet reputation points and you could see it yourself ;)
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
@DavidZ Reminds me of my favorite expression for things that are exasperating. I say "XYZ is like pushing an ice cube up a metal slide with a toothpick".
@ChrisWhite does he actually look like that?
user54412
@0celo7 You really are a creepy stalker :p

Q: How is it possible to say that the angular momentum is not parralel to the rotation axis?

Robert WernerAn evil moderator “dmckee” perturbs physics.stackexchange. dmckee does not know too much physics. An example (there are many more) is the topic "Rotation of a cube around its diagonal axis". From the comments made by dmckee it is clear he does not know the definition of the angular momentum, his...

Round 2.
@ChrisWhite if I were that I would have looked up his LinkedIn, found his lab, and asked his coworkers. Starting with Julian
user54412
@ACuriousMind Uhh, +1?
Hm, do we really have to VTC that one before we can delete it? I'm kinda running low on close votes lately.
Apparently someone is banking my share of the haul. I think I should complain.
@ChrisWhite Apparently, someone thinks this shows research effort ;)
04:52
@ACuriousMind Flag it as offensive if you prefer.
It's not offensive, is it?
@ACuriousMind I assume there is an additional sock, slightly better hidden.
@dmckee What's a sock? Fake account?
@0celo7 Well, it's kind of a personal attack. Not a very effective one, I admit, but still. Does that count?
@dmckee Or maybe a member of the community agrees that mods are evil
04:53
@dmckee I wonder why someone thinks we're the same person. Kinda weird.
@0celo7 It fits the "rude or offensive" flag description, the contribution is inappropriate for respectful discourse.
user54412
@dmckee disagree
@0celo7 Still with the wrong adjective.
user54412
Sep 11 at 0:18, by dmckee
user image
hehe
04:54
^^ That's a great stick figure.
@dmckee why wrong
user54412
And it uses color -- Munroe's got nothing on you
Is it ridiculous because it is about you? — Robert Werner 12 secs ago
Cause, I'm a mad scientist. There is a difference, ya know.
REKT
04:54
@ACuriousMind Ugh, that means I have to do something productive.
HOLY SH*T YOU GOT DESTROYED
@DanielSank I think it's because you and dmckee (and ja72) were the ones who engaged with that user in rather long comment discussions about the crap answers of their main account.
@ACuriousMind Oh.
@ACuriousMind I was foolish enough to image that he/she/it was merely confused at first.
> This account is temporarily suspended for rule violations. The suspension period ends on Dec 17 at 4:24.
04:55
And apparently the user is unable to believe there could be more than one person on this site who thinks their answers are crap.
What happened there
@0celo7 Eh no matter
They were a creepy people anyway
@Slereah ya
so what settlement is the best
the first one?
Although fuck you for killing that kitty :V
I usually stick with Sanctuary, yeah
It has a bunch of workshops
@ACuriousMind Indeed. I've seen a few answers by that user I found lacking and was met with a lot of resistance when trying to discuss.
04:57
@dmckee Faith in humanity. Not sure whether to envy or pity that
@ACuriousMind Well, it's a natural reaction at first.
@Slereah what are some others
are others more prone to attacks?
I hear on the BBC that there is a claim by a Kenyan mathematics professor of finding a proof of the Riemann Hypothesis.
What if there was a double agent...
Had to be sure.
@dmckee This is my skeptical face.
05:02
your skepical face is an octopus?
poor you
@0celo7 Ask what's his name for minutemen quests
You'll free a bunch of villages and they'll join you
@Slereah yeah I know
but which ones are the best
@dmckee Any link to that?
surely some are better than others
@DanielSank Well, yeah. There were, like three claim to solving the 4 color mapping hypothesis in the decade leading up to the accepted proof. But even if it is just progress, that's something.
05:03
there's one that's right next to a bunch of super mutants
got nuked by them
If he's serious, it should be on the arXiv by now.
@dmckee Progress would be great.
@ACuriousMind Yeah, you turn on the radio and listen to World Service...
what is a "radio"
@dmckee Wat?
05:04
A dude that doesn't publish his research is pretty suspiscious in my book
Isn't that right HAROLD WHITE
@0celo7 Obsolete audio broadcast technology.
@0celo7 You'll learn once you grow up and take an electromagnetics course.
@dmckee I refuse to believe that that anachronism could have the information before I can find it online.
@ACuriousMind Interesting position. Can we test it?
Well, World Service has a web page. And they are on twitter, I think.
05:05
I bet radio stations can get breaking news out faster than some guy can update his web page...
@DanielSank Trying to, failing to find anything
@ACuriousMind We need data, man!
@DanielSank pls use differential geometry to explain it
@Slereah Is the whole "Institute" thing a reference to the Red Scare
Nigerian professor scoops million dollar prize for solving 150 year old maths problem. 📻 http://bbc.in/1X3Fbyn https://t.co/jHwR8VeBGy
@0celo7 : The EM field is the curvature form of the connection on a U(1) bundle
05:06
@Slereah aye
@0celo7 It has some parallels I guess
every child knows that
but how do radios work
in terms of bundles
they gave him the money?
how did we not hear about this sooner
Well the electrons are in an associated $C^4$ bundle
There is a suspicious lack of actual mathy information about this
05:08
"According to the statement, “Dr Enoch first investigated and then established the claims of Riemann. He went on to Consider and to correct the misconceptions that were communicated by Mathematicians in the past generations, thus paving way for his solutions and proofs to be established."
I am also skeptical
> Dr Enoch had previously designed a Prototype of a silo for peasant farmers and also discovered a scientific technique for detecting and tracking someone on an evil mission.
$\partial_\alpha F^{\alpha \beta} = \mu_0 J^\beta$.
$\partial_\alpha(\epsilon^{\alpha \beta \gamma \delta} F_{\gamma \delta})=0$.
@ACuriousMind hehe
Yep, perfect qualifications for solving the Riemann
So what is the algorithm for the evil mission
05:09
@ACuriousMind he's an engineer
@0celo7 You track people on evil missions?
I think you mean $\star d\star F = j$
@DanielSank your lack of geometry training is embarrassing tbh
no one writes the Jimmy equations like that
and $dF = 0$
@0celo7 Well my diff geo skills ought to be poor, given that I have zero training. I don't know if I find that "embarrassing" though.
05:10
My favorite way to write Maxwell is the Jefimenko equation
@Slereah Oh. My. Suddenly I'm less optimistic. Damn you, BBC!
$\mathbf{E}(\mathbf{r}, t) = \frac{1}{4 \pi \epsilon_0} \int \left[ \left(\frac{\rho(\mathbf{r}', t_r)}{|\mathbf{r}-\mathbf{r}'|^3} + \frac{1}{|\mathbf{r}-\mathbf{r}'|^2 c}\frac{\partial \rho(\mathbf{r}', t_r)}{\partial t}\right)(\mathbf{r}-\mathbf{r}') - \frac{1}{|\mathbf{r}-\mathbf{r}'| c^2}\frac{\partial \mathbf{J}(\mathbf{r}', t_r)}{\partial t} \right] \mathrm{d}^3 \mathbf{r}'$
$\mathbf{B}(\mathbf{r}, t) = \frac{\mu_0}{4 \pi} \int \left[\frac{\mathbf{J}(\mathbf{r}', t_r)}{|\mathbf{r}-\mathbf{r}'|^3} + \frac{1}{|\mathbf{r}-\mathbf{r}'|^2 c}\frac{\partial \mathbf{J}(\mathbf{r}', t_r)}{\pa
user54412
the only thing embarrassing is that $\mu_0$
@Slereah I remember that from undergrad. Ugh.
user54412
clearly not an astronomer :p
05:11
or a mathematician
Jost treats U(1) gauge theory
he says something like
@ChrisWhite Oh, whatever. I copied from Wikipedia.
"constants are irrelevant"
@DanielSank wow
@dmckee You only say that because you are racist, probably
that's p. bad
@0celo7 Fix it.
05:12
whoa
race card
@DanielSank fix Wiki?
I already wrote the Lagrangian article, what more do you want from me
Apparently, this is the site for the conference where the alleged proof was presented
@0celo7 Your conversational skills are embarrassing tbh.
user54412
@DanielSank I'm actually trying to think if I have any physical constants left in my equations. I can't find any.
.doc and .docx documents instead of .pdf already look amateurish
Well, that could be a serious conference and it means that people are looking at the alleged proof, anyway.
user54412
05:13
We even set $\sqrt{4\pi} = 1$ at some point I'm pretty sure
@ChrisWhite ಠ_ಠ
$\forall x \in \mathbb{R}. x\approx 1$
user116211
@dmckee: An evil moderator “dmckee” perturbs physics.stackexchange.- surprised?
Yep, it's in the program: "14:30-14:50, Dr. Enoch Opeyemi, A Matrix That Generates the Point Spectral of the Riemann Zeta function"
05:15
@ACuriousMind Twenty minutes, eh?
@DanielSank my connection keeps timing out
dunno why
in any case, what do you want me to fix?
@0celo7 You really don't ever get my jokes.
@DanielSank what?
@0celo7 Whatever you were up on your high horse about. Rather than complaining just fix it.
they're probably not funny
@DanielSank sadly I can't fix everything wrong with you
good night
05:16
@0celo7 You were complaining about the Wiki article... I'm so confused.
The abstract doesn't say anything about the Riemann hypothesis at all
@DanielSank I was complaining about you having to go to Wiki for the Maxwell equations
every high schooler knows them
Does it say anything about evil intentions
@0celo7 In tensor form? Are you insane?
@DanielSank of course not
in bundle curvature form
05:18
Although one could think the part about the "spectrum of the Riemann Zeta function" is about the hypothesis, a proof of the hypothesis would not sound like this
they're not barbarians
@0celo7 The point is understanding what the equation says, not having it memorized.
user54412
I think I had Maxwell's equations memorized in any form for exactly freshman year of college. Hadn't seen them before, forgot them immediately thereafter.
@0celo7 You're either 1) from some special Russian city where they breed physics superstars, 2) Trying to be ironic, 3) On drugs.
@DanielSank 1) I wish 2) ironic = trolling? 3) I wish
user54412
05:20
Also, I just pulled a month's worth of commits the rest of the group made to the code. I ran some tests to make sure things that were working still are. They aren't :(
@ChrisWhite Dude, I was on your website the other day because Anna wanted to know who the guy I met from the internet was, and I barely recognized the photo. Facial hair matters a lot!
user54412
@DanielSank Linear combinations thereof allowed, I guess? Ironic Russian superbrain on drugs sounds terrifying.
@ACuriousMind lol
user54412
Those points are so not even close to that line.
05:20
@ChrisWhite Any chance you can set up commit hooks to run the tests?
@ChrisWhite wat
user54412
@DanielSank It's been a week or two. I now look like my website photo ;)
in any case
NO
someone deleted my wiki entry
I will investigate this in the morningn
@0celo7 lolololol
good night people
05:22
@0celo7 Good night.
user54412
@ACuriousMind my response exactly
also they scrubbed my electrovac lagrangian
THIS MEANS WAR >:(
::adds edit warring to the list of offenses::
user54412
@DanielSank I'm training the whole group this week on the regression tests I wrote. It's not clear though I'll have fixed the code before then.
Wtf does that mean
05:25
@0celo7 Are you part of the reason I find Wikipedia entries on physics topics largely useless? They're super high level and barely convey any useful information.
@ACuriousMind
Well maybe you need to RAISE YOUR LEVEL
@ChrisWhite Speaking from experience: If you don't make the tests run automatically people won't respect them.
@DanielSank I'm not aware of anything that I know that's high level, so probably not.
@0celo7 k
user54412
05:27
@DanielSank How can I do that though? We're storing the code on github, not our own server.
@ChrisWhite Aha! So are we! You can configure github to display tests results from other servers.
user54412
ooo
user54412
must look into that
We have a machine in the lab which runs the tests every time someone makes a pull request on github. The results are displayed, so if your PR breaks something it gets a big fat red X next to it. It's rather effective!
Look up Teamcity for running tests.
@ChrisWhite This really made a difference in how people respected the importance of tests and backward compatibility.
@DanielSank This kind of stuff is what the pro shops do, and coding scientists need more of it.
05:29
@dmckee Agreed.
Oh wait, am I allowed to talk to you? I am confused.
@DanielSank Well, our accuser is gone again, so I think it's OK right now.
@dmckee Ok, groovy.
From my brief brushes with actually getting code to work, I have the utmost respect for anyone who spends a significant amount of time doing that. I don't have the patience/motivation for that.
@dmckee I'm watching you.
@ACuriousMind Now I'm going to be thinking of Monsters Inc. lines. Your current avatar even kinda fits in.
@dmckee You think that's a monster? Speciesist!
05:35
@ACuriousMind Lack of patience/motivation is why you should use tests. One you write them, it's like having a babysitter watch your kids for you.
Well, at least I didn't accuse it of being a child.
From afar it resembles a satanic goat :P
@ACuriousMind If you like to save time, you write tests. If you like to hate your life, you constantly fix the same problems over and over by hand.
What he said.
But I didn't believe it until the first time I implemented a usefully complete test suite.
That happened the third time I tried to pull my dissertation analysis together into a coherent set of code.
But I blame at least one failure on CERNLIB. I think that's fair.
05:39
@dmckee Note that most languages now have rather nice test libraries. These libraries are designed to help you write and and run useful tests.
@DanielSank That would help. My first one was in Fortran 77. So I wrote the working bits as a library, and linked those to (a) the analysis and (b) the test program.
Blech!
@dmckee No no, that sounds really nice! Good on you for thinking to modularize!!!
Seriously, I wish more folks would do things that way.
