wouldn't theoretical astronmy rely heavily on cosmology and physics?

Slereah

Maybe for the most far off stars, yeah

like if you need to use the cosmic ladder and whatnot

Bradley G. Cooper

seem astronomy is observational (what we can see now)

*seems

ooolb

theoretical astronomy is just theoretical astrophysics

Astronomy used to be just star gazing once upon a time

ooolb

astronomy itself is mainly observational

ACuriousMind

10:02 PM

I feel pointless discussion about the boundary between astronomy and astrophysics is a recurring theme in this chat :P

Slereah

Not me

I go touch the stars

0celo7

@ACuriousMind I think a German would appreciate the dryness of the humor in this show

Bradley G. Cooper

@ooolb agree, thanks

ACuriousMind

@0celo7 Heh, perhaps. I think the most German-humored show I've watched is Der Tatortreiniger, revolving around a crime scene cleaner who keeps running into weird people when cleaning up :D

0celo7

@ACuriousMind lmao

10:06 PM

Dropped off laundry. Pick up at 9PM. At mexican fish taco place by the beach. Taco time, then off to code some more

Anonymous

@Cows Is the chat room your diary? :P

0celo7

Yeah, what's up with that

Do we really need to know when you pick up your laundry?

@Blue sometime lolz

lol

ACuriousMind

@0celo7 It's oddly hilarious, but I suspect its humor is rather peculiar to folks from other countries. It's on German Netflix, no idea whether it's available anywhere else.

10:11 PM

i'd love to spend a night in a laundromat with @Cows, @Secret, @BalarkaSen and @Slereah. just the 5 of us.

0celo7

Normally I'd be upset at being left out, but that sounds awful.

Slereah

I don't use a laundromat

I have a washing machine

Cows

Hehe it will be a fun night for sure :P

ooolb

@0celo7 weirdos only

Emilio Pisanty

@Keepthesemind Indeed. And there already are people doing that work; I'm happy for them to have a crack at it. I'm more interested in doing actual physics.

ACuriousMind

10:13 PM

I don't even know whether there are laundromats in Germany...

@ooolb You'd have to lock yourself out by that criteria ;)

@ooolb I wouldn't classify you as weird :)

ACuriousMind

If people washed more by hand, we wouldn't have to move so many washing machines around - there have been oddly many moves by friends recently, and the washing machines are always the most annoying :P

0celo7

@ACuriousMind People wash clothes by hand?

ACuriousMind

Not here, but apparently in India :P

It's not bad. You can wash clothes pretty well with hands

And a good detergent

@0celo7 Ya, better if you hide your strong opinions if you can't be respectful.

Using a laundry machine is already a pain in the ass

I can't imagine actually hand washing

Slereah

How is it a pain

Put laundry in

Put detergent in

Turn machine on

wait

ACuriousMind

^

Slereah

take laundry out

0celo7

When you take it out, it's all wet

then stuff falls on the floor

then you have to dry, and some stuff shrinks while other stuff isn't dry

Slereah

that's why you put it to dry

ooolb

10:24 PM

@Blue you don't even know anything about me

0celo7

then you fold it and hurt your back from hunching over

ACuriousMind

@0celo7 Huh? Just use a basket to transport the laundry! (Also, very few people here use a dryer)

0celo7

@ACuriousMind when moving from the washer to the drier

I'm not putting it in a basket to move it a yard

socks always fall on the floor!

@ACuriousMind actually you might not enjoy this show

ACuriousMind

@0celo7 The method of just letting it hang to dry seems less...prone to complications that way

0celo7

@ACuriousMind I've had to do that a few times

it's awful!

the clothes are always stiff and it takes like a day

Anonymous

10:27 PM

One good thing here is that clothes dry in 1-2 hours....too much sunlight :p

ACuriousMind

"stiff"? How so?

Also, what's the problem with it taking a day? Do you only wash when you have literally nothing left to wear? :P

Anonymous

@ACuriousMind Bachelors tend to do that ;)

0celo7

@ACuriousMind I usually run out of socks first

ACuriousMind

@Blue Oh, I know that all too well :P

0celo7

but barefoot is degenerate (hate incoming) so that's when I usually wash

barefoot/sandals/etc. i mean

esp. in Winter

ooolb

10:30 PM

@0celo7 inside though

do you wear socks when you're in your room

0celo7

of course

ACuriousMind

@ooolb Not wearing socks is only feasible if you've got a clean floor ;P

0celo7

hey

my floor is clean

ooolb

why would it be dirty?

Anonymous

Slippers are more comfortable than socks though (at least for me)

10:32 PM

@ooolb this

this isn't a German sex club, what do you expect my floors to be covered with?

@Blue that's what vacuums are for

ooolb

@Blue dust doesnt settle in areas where you walk around in

0celo7

I need to clean my PC

it's probably starting to accumulate some dead skin

Anonymous

Vacuums don't clean well enough. You need to wet wipe your floor with phenyl or something like that so that they are germ free

Q: Is it 'Phenyl' or 'Phenol' that is used as a cleaning agent?

I often see Phenyl written on cleaning agents in stores. Here are some examples: One day, a guy standing beside me at a store picked up a bottle of phenyl/phenol and he said, "The big corporation got it wrong. It's phenol, not phenyl." I looked up the definition of Phenol, and it reads: ...

@ooolb ::ahem::

ooolb

sorry

i used to be a germaphobe

i washed my hands like 50 times a day and after several weeks they would bleed from dryness

and i realized i was an idiot and befriended the germs

i don't even use harsh soap anymore

currently been using a pure glycerin soap thats dyed blue

like 3 ingredients

0celo7

10:44 PM

I use a mild acid wash

doesn't try out the skin

you should watch this show. A little casual racism, homophobia and a lot of anti-psychiatry, but it is a ganster show

@ACuriousMind did you watch GoT S7?

ACuriousMind

I...think I forgot?

0celo7

10:59 PM

@ACuriousMind Ok, what is up with that first pinned message?

ACuriousMind

I guess someone pinned it because they thought it should stay there a bit longer? (It wasn't me)

0celo7

huh

is it a common problem in this chat?

ACuriousMind

Not more common than its other problems in my experience :P

It's one SE generally takes rather seriously, though

If I take the average of some data points, can the result have more significant digits than my individual data points?

Mithrandir24601

@heather !!! The QC proposal is almost past the definition stage!!!

heather

!?!

::goes to check::

ooolb

@ACuriousMind what now

Mithrandir24601

Just 2 more votes :D

heather

=D =D

ACuriousMind

11:30 PM

@JannikPitt No

ooolb

i used computer modern

Jannik Pitt

@ACuriousMind Interesting, because our Prof said it can get arbitrarily precise if you calculate the standard deviation too

ACuriousMind

Or, well, it can if the errors on the data point vary. If you don't have the same error on all data points, you need to do a proper propagation of uncertainties, which for the average just means taking the average of the uncertainties

ooolb

@JannikPitt but you're not really getting more precise results from that

depends on context i guess

ACuriousMind

@JannikPitt There is two different kinds of errors on the average - one from the statistical standard deviation from averaging, which can indeed get arbitrarily small, and the systematic error from the imprecision of your measurement which doesn't really get smaller by averaging.

You can often get away by assuming the systematic error to be "small", though

heather

11:35 PM

oh my gosh!

@Mithrandir24601 it's in commitment!

someone upvoted!

Jannik Pitt

We were given a list of data points and we had to calculate the average and the standard error (to write it as value +/- standard error). If I average in this situation, can the average have more significant digits than the individual data points?

ACuriousMind

@JannikPitt If you have no systematic error given on the individual data points, yes.

0celo7

ACM is now an experimentalist

ACuriousMind

All these boring labs weren't entirely for nothing :P

Jannik Pitt

Okay thanks!

ACuriousMind

11:37 PM

You're welcome!

Jannik Pitt

Have to say I really am not a big fan of these experimental classes haha

Mithrandir24601

@heather :D YES!!!!!!! :D Now, just to get it to beta...

Avantgarde

Me neither. I don't miss them. At all.

ooolb

i love experimental classes

because you can talk to people

heather

so what, do 200 people need to commit?

ooolb

11:40 PM

lectures are so boring

just read the book and go to office hours if you want some extra feedback

Avantgarde

You can talk to people in theory too. A lot of talking is done there, in fact

ooolb

you can't talk over the lecturer

nobody talks in theory classes

ACuriousMind

I will always remember staring completely hungover at a painted spinning top under a flickering stroboscope to measure its rotation frequency. That was fun :P

Mithrandir24601

First step, here: Peoples of hbar! The Quantum Computing proposal is in the commitment stage!

Avantgarde

Random chit chat, or talking about the topic? If it's the former, then of course not :P

ooolb

11:42 PM

@Avantgarde during the class?

doesn't matter what

ACuriousMind

I spent a good chunk of lectures discussing what was going on with my neighbours

ooolb

idk maybe you guys are different

ACuriousMind

Doesn't work if you're too close to the lecturer, of course

Avantgarde

Welcome to TMZ 101

ooolb

in my qft class the prof didn't ever pause and we were like 1 meter away literally

if you discussed to your neighbours he'd stop

Mithrandir24601

11:43 PM

@heather 200 people, 100 of which have to have > 200 rep on other SEs, then there's another weird weighted thing that depends on rep that needs to be fulfilled as well

ooolb

and be like

ahem

Avantgarde

So what did you expect him to do?

Jannik Pitt

Well at the moment my experimental class consists out of interpolating data points by drawing graphs on graph paper

ooolb

@Avantgarde i don't expect him to do anything different

i'm saying you can't talk in lectures

and gave an example

and if it's a first year course with 500 kids then

what's there to talk about?

Avantgarde

Bitcoin

@JannikPitt Paper? You don't use computers?

ACuriousMind

11:46 PM

My lab course too had a weird hang-up where the first parts had to be completed by drawing graphs without a computer

Jannik Pitt

@Avantgarde Asked that myself too, the lecturer said at the beginning we will only be using graph paper

Avantgarde

I remember using paper in high school. University .. I don't think so. At least not for physics, no.

Jannik Pitt

I'm in first semester

Avantgarde

@JannikPitt I see. Well, it is what it is. But would you be taught how to plot and do analysis on a computer?

Because that's how it's done in real life

ooolb

when you do it by hand you learn what you're doing though

if you do it with a computer too early you may not know what you're really doing

and just write down the numbers it gives you

ACuriousMind

11:49 PM

No, you really can't do a least squares fit by hand :P

Avantgarde

Well it's university. When do you want to work with a computer for the first time? When you actually get a job?

ooolb

no i mean like

acm's lab

ACuriousMind

You're not learning what you'll do on the computer, you're just drawing lines by eye

ooolb

had it by hand at first

i'm not talking about lines.....

i meant other data stuff too

ACuriousMind

Drawing graphs that aren't lines by hand is even worse!

0celo7

@ACuriousMind Do you remember if the Morse index is monotone increasing?

Jannik Pitt

@Avantgarde I guess we will learn that later on (hopefully), but we have to do everything by hand in the first lab classes

ACuriousMind

@0celo7 increasing in what sense?

Avantgarde

@JannikPitt Okay. I think you will. Also, there might be a course on computational methods in physics.

0celo7

11:52 PM

@ACuriousMind Along the geodesic

ACuriousMind

What geodesic?

I don't think I know the Morse index you're talking about :P

0celo7

...what do you think I'm talking about?

ACuriousMind

I know what the Morse index of the critical point of a smooth function is, but I have no idea what geodesic you're talking about

0celo7

ok, never mind then

@ACuriousMind I think it should be true that if a geodesic has no conjugate points, a smaller one shouldn't either
