Emilio Pisanty

10:00 AM

which is pretty misleading

John Rennie

Yes, it's a bit odd that they regard a statistical error of 0.85 attoseconds as zeptosecond precision.

I suppose zeptosecond precision actually means sub-attosecond precision

Emilio Pisanty

@JohnRennie yeah

I mean, on some level, there's some blame on scientists trying to spruce up results

John Rennie

But on the list of crimes against science committed by New Scientist I don't think this ranks highly. And I still read and enjoy New Scientist every week.

Emilio Pisanty

people will claim they have "attosecond pulses" even if they are 0.8 fs

Dawood ibn Kareem

@JohnRennie I don't consider that "sub-attosecond" at all.

Emilio Pisanty

10:04 AM

@JohnRennie yeah, this one isn't major

@DawoodibnKareem how come?

John Rennie

@DawoodibnKareem well it is less than one attosecond ...

Dawood ibn Kareem

I would expect "attosecond precision" to mean $\pm 0.5$ as. They didn't achieve that.

If you're not $\pm 0.5$ as, then you're not measuring to the nearest attosecond.

Emilio Pisanty

@DawoodibnKareem well, most people in ultrafast physics would disagree with you

Dawood ibn Kareem

And yes, I know I'm blurring the distinction between "standard error" and "absolute error". Humour me.

@EmilioPisanty Really?

I guess I need to hit the books again!

Emilio Pisanty

@DawoodibnKareem yeah, any measurement with standard error under 1as would be counted as sub-attosecond precision

it's probably not something you'd learn in a book, either ─ more of the informal chats in a conference kinda thing

Dawood ibn Kareem

10:07 AM

Kind of seems like cheating to me.

Emilio Pisanty

@DawoodibnKareem ¯\ _(ツ)_/¯

Frankly, I would tend to put the boundaries at $\sqrt{1000}$ of whatever scale you're doing

Dawood ibn Kareem

So if I'm within a month, I can say I got the day right?

Emilio Pisanty

@DawoodibnKareem =P no

but if you're in a regime where orders of magnitude are a bit more fluid, then it makes more sense to put the halfway spot on a log scale rather than a linear scale

Dawood ibn Kareem

Oh, I see what you mean.

Emilio Pisanty

so e.g. you could say that a femtosecond pulse can last between 1 and 31fs, and between 31fs and 1ps it's a subpicosecond pulse

Dawood ibn Kareem

10:10 AM

So if I'm measuring an electron coming out of helium, I really only need to care whether it took zeptoseconds, attoseconds, femtoseconds or picoseconds.

Emilio Pisanty

ditto with attoseconds, you can say subfemtosecond between 31as and 1fs, but you only get to say it's an attosecond pulse if it's under 31as

Dawood ibn Kareem

@EmilioPisanty I'll remember that next time I go for my "lunch hour".

Emilio Pisanty

@DawoodibnKareem ¯\ _(ツ)_/¯

though to be honest the factor of 31 is a bit weird

Dawood ibn Kareem

It does kind of makes sense as $\sqrt{10^3}$. If anything's weird, it's the 3.

Emilio Pisanty

it feels a bit more natural to up it to 100

but that kills the objective criterion

so

¯\ _(ツ)_/¯

Emilio Pisanty

so that one's just a standalone diacritic?

@JohnRennie I do

It's just not very appealing

Dawood ibn Kareem

10:17 AM

"standalone diacritic" is an oxymoron.

@JamalS Hi @JamalS. I think that removal of complete answers to homework-like questions is a little bit time-sensitive: if we politely request that the answerer edit the post, and wait, and the asker returns and sees the complete answer, then we fail at our goal of "let's not be a homework service."

It is not clear how quantum field theory mesh with entropy, though for quantum mechanics, we are starting to have some leads for far from equlibrium systems

John Rennie

@0celóñe7 do SSDs have a clock?

0celóñe7

skype is fucking malware

@BernardoMeurer I need Linux now

@JohnRennie no it's because I had some files in ./documents on my 2TB drive worth 100+GB

I copied those over

@JohnRennie So, amazingly, GitHub Desktop is stored under /users/--/AppData

John Rennie

The reason for the apparently odd location is to allow for roaming profiles. On an Active Directory domain you can configure your profile so it gets replicated to whatever PC you are using.

This is actually pretty cool because you can go to any PC in the domain, log in, and get your desktop and all your files.

Though on a standalone PC it's just unnecessary baggage.

0celóñe7

So do I have to redownload it?

John Rennie

2:00 PM

I've never used GitHub desktop - I always use git from the command line - so I'm not sure.

0celóñe7

I just did it

Time to clean up this hard drive now

@JohnRennie Do you know Windirstat?

@JohnRennie Ok switching profiles completely broke the search function

it can't find anything

John Rennie

@0celóñe7 Yes, though being me I use a command line tool instead.

@0celóñe7 I almost never use the Windows search. I'm a bit surprised you find it so important.

What the hell happened

and my hotkeys are broken

why can't anything be easy

John Rennie

2:05 PM

Presumably it needs some time to rebuild the search indices after you moved all your files.

0celóñe7

@JohnRennie I didn't move any files.

John Rennie

A cynic might point out that if you'd used a local profile to start with, as I was trying to suggest before you raced off and used an MS one instead, you wouldn't now be having all this strife.

0celóñe7

Well I didn't fucking know that Microsoft is retarded

0celóñe7

I don't understand how the search bar working on one profile but not the other is a trap

It doesn't make any damn sense

John Rennie

I'd probably delete and rebuild the search database

Then click Indexing Options

Then click the Advanced button

Then click the Rebuild button to delete and rebuild the search database

0celóñe7

@JohnRennie How long will this take?

John Rennie

user228700

What are u talking about?!

John Rennie

@Kaumudi.H It's true.

Being surrounded by people you love in place you love causes the brain to secrete elevated levels of dopamine and serotonin.

user228700

Ah, haha, that :-)

John Rennie

Those are the neurotransmitters that basically make you feel good.

user228700

Well, yes, I guess.

John Rennie

But your neurons can vary the density of dopamine and serotonin receptors depending on the neurotransmitter levels.

user228700

I know, I know :-) Heck, we even talked about this once before! Relating to caffeine or something.

John Rennie

5:42 PM

And when you're continually producing the neurotransmitters the neurons decrease the receptor density.

Ah yes. Caffeine affects different receptors but the same principle applies.

So the thing is that right now you are in effect suffering from neurotransmitter withdrawal symptoms.

@Blue We didn't really have sex ed, I lied :-P I looked it up myself when I came to know about the phenomenon. There is a TED talk...

John Rennie

@Kaumudi.H Good grief, your browser history!!

user228700

HEY! It was in the spirit of learning and I did learn all this crap about receptors in our brain because of it!

@Kaumudi.H Story of every teenager. :'D

John Rennie

@Kaumudi.H That's what they all say :-)

user228700

:-( I have to remember that by being honest, I brought this upon myself!

THERE IS A TED TALK! And it's quite famous too!

Well, well. No need to explain further. We understand ;)

John Rennie

Paula Hall?

user228700

Sigh. I should probably go knocking on every door to find my roommate...

John Rennie

Gary Wilson?

user228700

@JohnRennie No, Ran Gavrieli.

This one.

John Rennie

@Kaumudi.H I wouldn't do that. Just lie in bed and read a book.

Good chance to catch up on some of the reading you've missed over the last two years.

user228700

:-) I've brought The Age of Reason by Satre with me.

John Rennie

@Kaumudi.H ah, that was the next one down in the Google results.

@Kaumudi.H you have to be kidding. You've let Balarka Sen lead you down the path to literary damnation.

user228700

I'm not x'D I found a dusty copy of that book in my house the day I was packing most of my crap!

user228700

You saw my bed in the picture, no? Not to boast or anything (:-P) but it's extremely comfortable!

John Rennie

5:54 PM

Irony again?

user228700

Actually, no, it is extremely comfortable :-P

John Rennie

Perfect for reading in then. That was one of my luxuries when I was a student.

user228700

BTW, @Blue: Have you bought a scientific calculator yet?

user228700

@JohnRennie Nice! I even have two fluffy pillows!

@Kaumudi.H I had a spare one in my home. Why?

user228700

Ah, OK. What brand is it? I gotta buy one soon and since I'm holed up here (and my roommate's gone), I need help :-P

It's a very basic one

John Rennie

@Kaumudi.H doesn't everyone just use their phone these days?

user228700

:-( We're not allowed to use phones on campus.

We even take laptops to our classroom :P

user228700

Well, the "campus" is just the main building so.

user228700

@Blue Ah, OK. Is it possible to enter matrices?

PhyMan

Do they conduct raids and all?

user228700

Lol, no, no.

John Rennie

Maybe ask if the department recommend a make of calculator?

user228700

5:59 PM

@JohnRennie Hmm, OK, I'll wait till tomorrow. My EE prof. did recommend one but he was too vague about the specifications. Hopefully, he'll tell us tomorrow.

Anonymous

@Kaumudi.H Yeah. But it is not very convenient for matrices. Better buy Casio fx-991ES PLUS

PhyMan

@Blue I have that one, and it's very helpful during the statistic exam for finding all the regression equasions :P
