how do you write a series of mathematical statements in a paper without just spewing out mathematical statements? how do you "connect" them?

@heather By adding sentences that exhibit the thread of logic between them? You must have a reason for wanting to write down these statements, after all.

Slereah

Or just string them together

It worked for the Principia Mathematica

@ACuriousMind well, yes, but the thing is, I already described what I'm doing in a different section, and it seems rather redundant to rewrite it all for the mathematical statements.

10:26 PM

@Slereah For a certain value of "worked", yeah

@Slereah they were cool enough they could get away with that

this isn't the Principia Mathematica

@JaimeGallego 4166.67

Slereah

@heather then rework the structure or repeat

@heather That would tell me that either you're worrying too much about the current section or your other section was far too detailed

@ACuriousMind the other section was about a simulation i did

this section is about mathematically what is happening as the gates are applied

10:29 PM

@ACuriousMind Can you help @KristinaL plox?

I don't know physics

I know nothings

so the first section definitely wasn't too detailed because it was kind of important i need to describe the simulation, and the second section also seems important.

and so the dilemma continues.

nvm, figured out a way to word it.

@BernardoMeurer @KristinaL The equation is not $W = F s$, but $\mathrm{d}W = F\mathrm{d}s$. Taking total work as force times distance only works if the force is constant over the distance, but in this case it increases with the distance.

@JohnRennie Is that really you?! :-o I find this picture absolutely adorable!

@heather I was just about to say that your problem seemed to be a bit too specific to be usefully solved without reading what you already have

@ACuriousMind God bless your large potato-filled German soul

10:35 PM

Oh I see, thank you! @ACuriousMind

@JohnRennie Damn! You were so cool looking when you were my age

user228700

@BernardoMeurer He certainly made for a much cuter nerd!

^ouch

@Kaumudi.H What the hell dude

What did I do to you

@Kaumudi.H ouch

user228700

10:37 PM

No, no!

yes yes

and please people dont flag that

it's alright, @BernardoMeurer, I'm no judge of cuteness, but you certainly don't look as crazy as Sir Rennie =P

user228700

@Bernardo: I was just about to add that you don't even look like a nerd to begin with!

@Kaumudi.H Bernardo is the cutest nerd I know

@Kaumudi.H You're just adding insult to injury now

10:38 PM

@Kaumudi.H the nerd is one of his best qualities

@KristinaL, something tells me you may be a tad biased (as does my poor memory) =)

@Kaumudi.H double ouch

user228700

Dang it, @Bernardo looks like a really cool geek to me!

@heather Only slightly ;)

@BernardoMeurer, ready your potato computers

@heather You haven't seen me trying to cross-compile the kernel on a calculator

10:40 PM

busted! in JR's picture you can see a joint in his tent, by his leg

2

@ACuriousMind is it poor form/general idiocy to use \subsubsection?

@Kaumudi.H I'm no geek! That's for people that like series or something

@BernardoMeurer fair enough

@BernardoMeurer doesn't look like a nerd, he looks like batman, I have proof:

user228700

It's 4 AM, do forgive me, @Bernardo: U're a computer geek, aren't you?

10:41 PM

Oh my god

Physics Guy

Hey guys.

@Kaumudi.H I'm a computer nerd

@AccidentalFourierTransform I don't see it

It's a crucial distinction

@ACuriousMind It's his knee

@KristinaL (hi!) and how do you know Bernard? now wondering if he recruited you for this room o_O

10:42 PM

@BernardoMeurer ...he smoked his knees?

@ACuriousMind It's a joint by his leg dude

user228700

I pray that you forgive me, @Bernardo. If you identify as a computer nerd, then I respectfully retract the statement that I made above. It's 4 AM, pls.

@ACuriousMind youre a good kid. You dont even know what a joint looks like

@BernardoMeurer arrrrrrgh

@Kaumudi.H It's okay :P

@ACuriousMind THE GENIUS HAS FALLEN

10:43 PM

@AccidentalFourierTransform Not sure whether I feel flattered or insulted you think that :P

@AccidentalFourierTransform ACM is the biggest stoner in this room

@AccidentalFourierTransform ...a joint? (all I can think of right now is, like, ankle or elbow joint)

actually, I take that back

@ACuriousMind We all know that there is no fun in Germany

I don't want to know

@AccidentalFourierTransform That's right! How many Germans do you need to fix a lightbulb? One. We're efficient and don't have a sense of humor.

10:44 PM

Feb 2 at 20:54, by heather

@ACuriousMind "banged" his cousin...i thought i read somewhere he hit his younger cousin or something when she was born. am i misunderstanding something?

← has german last name, maybe some )( blood

@AccidentalFourierTransform oh gosh

no

just no

@AccidentalFourierTransform let's not go there again :P

user228700

For the record, BTW, I too don't see the joint.

i need to get away from you heathens =P

10:45 PM

@ACuriousMind which means youre perfect as chat room mod :P

@heather Look away, we cannot corrupt you

@heather Read "heathers" at my first try, was confused.

@BernardoMeurer heathers highly indoctrinated now that she gave her session o_O

@heather ^

10:46 PM

I'll just say that before heather started talking to me she didn't know who Tux was

now I have Linux installed on a chromebook

Nor was she an Open Source Zealot

Yes

Very well

now I use github

and LaTeX

Get a calculator now

thanks to all of you

@BernardoMeurer I have a graphing calculator, you know

Jaime Gallego

10:47 PM

This really is a true story, and she doesn't know I put it in my comic because her wifi hasn't worked for weeks.

@AccidentalFourierTransform srsly? how about someone photoshop it with a red circle & lets all star it :) ... maybe there is even more correlation to easy rider than was previously known! o_O

Let's turn a calculator into a chromebook with linux

@BernardoMeurer I have a TI-89

Hmmm

← has actual stuffed Tux

10:48 PM

@heather What ever you do, do not modify any potatos at his instruction

@ACuriousMind you know, I think we might have a potato in the house...

@vzn tomorrow morning JR will read my message in the starboard and he'll be "oh fuck" for a second

I think we could make the kernel see the TI-89 display as a TTY

Somehow

It might need an evil driver hack

what is a TTY?

10:49 PM

@DanielSank you awake?

@BernardoMeurer please keep in mind that if I take a screwdriver to my graphing calculator my parents might not be too happy...

howdy folks

@heather Hopefully we will not need that much

maybe, but probably no

@Skyler hello

Jaime Gallego

@heather A legacy term for the terminal

10:49 PM

TTY = teletype

i.e. a terminal

@BernardoMeurer with you, any "maybe" scares me =P

@BernardoMeurer ah, I see.

@heather why would you be taking a screwdriver to it though?

Iff the TI-89 has a UART somewhere we could use that to bypass TI's software protection

But I don't think it has an UART anywhere

@AccidentalFourierTransform hey since youre around can you update the physics meta post with heathers session? after we fully finish the "maryj" thread ofc :P

Universal asynchronous receiver/transmitter

@Skyler you never know with Bernardo. ::shrugs:: (I was just trying to convey that I don't want to break my calculator =P)

@BernardoMeurer a UART?

A universal asynchronous receiver/transmitter (UART /ˈjuːɑːrt/), is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable. The electric signaling levels and methods (such as differential signaling, etc.) are handled by a driver circuit external to the UART. UARTs are commonly used in conjunction with communication standards such as TIA (formerly EIA) RS-232, RS-422 or RS-485. A UART is usually an individual (or part of an) integrated circuit (IC) used for serial communications over a computer or peripheral device serial...

^?

10:51 PM

@vzn sure. Ill need the link to the transcript though. Can you find it for me?

@heather Yep

Basically, serial communications

@AccidentalFourierTransform here

So, a way to talk to the underlying software in any hardware

well, not any

Hardware that supports it

@ACuriousMind thanks

@ACuriousMind thx man! :)

10:52 PM

i think there might be some port for uploading programs/docs to it via the computer

never used it though

I might get one of these

to tinker

I should buy books though

who cares

Is yours the titanium?

@BernardoMeurer nope, just the regular one

please make sure that I didnt mess it up

Fuck, 60 bucks

ouch

@AccidentalFourierTransform looks okay to me. gracias

10:55 PM

@heather now you're already learning UART stuff too

@AccidentalFourierTransform thx! ps trying to remember were you working on masters or phd?

@Skyler no, Bernardo just mentioned it. =)

@Skyler I'm the seed of bad ideas

@vzn np. Im working on my masters thesis right now.

@AccidentalFourierTransform iirc, astro?

10:58 PM

@vzn kind of. General Ralativity, about the symmetries of asymptotically flat spacetimes

anyway, I should leave now

@AccidentalFourierTransform ok, plz continue to mull over chat session, am sure youre a natural, & feel free to do it before finishing the masters 1st... :)

lol I'll think about it

bye for now

ciao people

@AccidentalFourierTransform yeah thats what they all say :| bye :)

@AccidentalFourierTransform have a good night =)

hmm...advice for writing the conclusion to a paper?

so now that AFTs gone, who figures he made up the whole joint thing? he seems like a real troublemaker sometimes :P

11:03 PM

@heather Don't start it with "In conclusion"

@KristinaL there went my first draft =)

(literally, I just had the words "In conclusion" and then the cursor blinking)

Make the reader feel bad

Call him/her names

Because by then he already red the whole paper

so you can insult him

and make him feel like he wasted his time

@heather Second grain of advice: Don't listen to @BernardoMeurer

it's great

@BernardoMeurer not really - a lot of people just read the abstract and conclusion to see if they want to read the whole thing

11:06 PM

@heather They will get interested by the insults then

I got a job after calling my Serbian professor a Dick in Serbian, he respected my resolve to curse in his mother tongue

@heather The conclusion of your paper should contain the outcome of what you're writing; the "so what?" effects of the purpose. Basically why your reader should give a crap about what you just wrote.

@KristinaL also interested in dark matter, just noticed a Physics question on topic that indicates its ~80% of milky way galaxy. what level of physics class was it?

@KristinaL, so definitely not a summary. Should it include anything about what future research might entail?

@heather Well, really depends on what you have done. If you plan on further investigations of some aspects (or don't plan on them, but think they should be done), mention that. If you have future applications in mind, mention those.

If there is something to be said in summary that you haven't said before, also say that. If some important takeaways are buried in the midst of not so relevant stuff, stress them again

Danu

@ACuriousMind Check this out

Gukov having some humor (this is the abstract for his talk at a workshop)!

11:12 PM

cheesesteaks are good

@heather yes, not a summary. You should mention the main topics you discussed in your paper, but don't just restate them. Mentioning future research (and why it would matter to the audience or to your subject) is a great idea. :)

@KristinaL okay. thank you =)

thanks @ACuriousMind

@Danu Heh. Now I'm hungry.

Danu

@ACuriousMind I had the same reaction :(

Fortunately, I have food left :)

Danu

11:18 PM

I don't...

Why are you always out of food!

Maybe you should get another roommate for the sole purpose of raiding their foodstores ;P

@Danu Don't you have a girlfriend who cooks really well or something?

is it important to have a section in a paper detailing previous research in a topic or field?

even if the paper doesn't build directly off a previous paper?

@heather If it is not relevant to understanding what is going on in the paper and not the basis for it, I would not expect it unless it's a review article

@ACuriousMind okay

11:50 PM

what up peeps

DanielSank

@heather it's common to put references to relevant prior work in the introduction.
