lol - I can tell what book this question is from even without the OP mentioning it

user54412

there's only one book out there that makes such heavy use of such a crazy character ℛ

@user23709 A quick check on wikipedia helps: en.wikipedia.org/wiki/Moment_of_inertia

@ChrisWhite and it's not even the right R, really

user54412

@DavidZaslavsky indeed - I was studying from that book at the same time I was learning TeX (by typesetting my homework) - the effort I spent to get a lowercase script letter in the right font!

user54412

in the end I think I settled on a non-vectorized character, since I couldn't find anything else

David Zaslavsky

yeah, it annoys me to no end that you have to jump through hoops to get the Griffiths' r in LaTeX

Q: Script-r Symbol

The near-ubiquitous undergraduate reference on electrodynamics, "Introduction to Electrodynamics" by David Griffiths make extensive use of a script-r symbol, defined to be \vector{\scriptr} \equiv \vector{r} - \vector{r}^{\prime} and looks like: Although the question of how to produce such a s...

@DavidZaslavsky ^ If only I had known

user54412

@dimension10 there's no lowercase script naturally in tex, unfortunately...

user54412

and for some reason Griffiths went with that

user54412

actually even those answers on tex.SE are pretty hack-ish

Crazy Buddy

@ChrisWhite: Ohh.. so, you've finally woken up sunshine :D

David Zaslavsky

5:25 AM

@ChrisWhite lol, half of them reference my package

user54412

@DavidZaslavsky WHAT?!? You wrote physymb? Cool!

David Zaslavsky

Yeah, although I didn't realize much of anyone used it

Crazy Buddy

5:49 AM

Okay... Do we need eye?

we're currently busy with vision, so do we need it?

@ChrisWhite: Maybe you can suggest a synonym for vision... ???

David Zaslavsky

@CrazyBuddy nah, I'm pretty sure eye can be merged into vision. Then we figure out what to do with vision

user54412

Wait why am I the go-to person for vision?

Crazy Buddy

@DavidZaslavsky Yeah... that's why I requested Vision specialist :D

@ChrisWhite For suggestion, I need 5 score (well, I barely have 1 or 2)...

You told me that you're going to quit AP anyway :P

user54412

@CrazyBuddy Anyone who can post on meta can suggest: meta.physics.stackexchange.com/questions/175/…

user54412

that was made precisely because people can have good suggestions but not enough score to do it the "official" way

user54412

6:00 AM

and yes, I thought I would quit, and lead a quite astrophysicist's life...

Crazy Buddy

I know... But, voting in meta - everyone will do...
I don't think many users know that there's some option called `synonyms` under tags ;-)

Then, who's gonna vote for synonyms...

user54412

...but I just had to answer... and that question is STILL in the hot questions list!

Crazy Buddy

If it doesn't reach 4, it will stay there forever -_-

user54412

sigh - one day the world will care about all the cosmology and GR I spend so much effort answering...

Crazy Buddy

@ChrisWhite Ohh... so you agree that you're spending much time in Phys.SE than anything :D

Crazy Buddy

@ChrisWhite What..? Why? Did you ask him to delete it?

user54412

I think he just deleted it to keep the page clean

Crazy Buddy

Clean..? What's the meaning of a +1 there?

user54412

6:10 AM

@CrazyBuddy someone (Manishearth?) voted, but then Manishearth realized this was a no-brainer and implemented it

user54412

the rocket and rocket-science questions were basically the same

user54412

it would be like having condensed-matter and condensed-matter-physics

Once you become a physicist, there is some risk that you won't be able to talk with normal people.

Does this apply to family too..?

user54412

Yes

Crazy Buddy

Okay... So, the people who starred it (7 or 8 I think) have experienced it o.O

In my home, no one's believing me that I'm spending most of my time in this site :D

And, everyone fears to come near me my room, else I'd start some lecture (on anything) :P

Ohh.. And I forgot to mention that the same happens in colg...

Wondering whether this happens to @Manish ...

Crazy Buddy

6:28 AM

BTW, How you guys make "lol"s in English ??? :P

Because, I can't make one with my limited knowledge in a few bunch of words I've worked out hardly....

Still, I have to keep in touch with my word web if Gugg or twistor comes in :)

user54412

@CrazyBuddy I don't quite understand - are you asking how to make jokes? how to write laughing sounds with text? if there's another word for "lol"?

Crazy Buddy

LOL - I KNOW HOW TO WRITE "LOL" Grr....

Of course, it's the first one I want :P

user54412

What does that have to do with English then?

Crazy Buddy

@ChrisWhite Actually, everyone here speaks English.. hello? I think you didn't get my question o.O

user54412

apparently not :P

user54412

6:35 AM

maybe I'm tired

user54412

maybe i don't speak English well enough to understand :P:P

Crazy Buddy

@ChrisWhite In my frame, everyone speaks the same way, which I can't understand :D

Crazy Buddy

@ChrisWhite: I have a thought of making an ad for Astrobites...

(Community promotion ya know) :P

David Zaslavsky

7:45 AM

Sure, that could be a good idea

Crazy Buddy

I'll try... Haven't worked in photoshop much :D

Crazy Buddy

7:58 AM

@DavidZaslavsky: Completed... But, not much visible I think so :/

1 sec...

What do you think?

David Zaslavsky

eh... honestly that doesn't make much sense to me

e.g. what's so special about supernovae that makes them worth mentioning?

And it doesn't really say what astrobites is

Crazy Buddy

Ah... Okay.. Maybe, I'll have to think patiently for a while :D

Maybe, I'll remove the whole background and just keep astrobites along with the bite planet...

(and write something more)...

Crazy Buddy

8:16 AM

@DavidZaslavsky Regarding the supernovae part, I thought of mentioning some astrophysical parameter..

David Zaslavsky

nah, I think that just distracts from the main message

I'd say keep it simple

Crazy Buddy

Okay.. I get it :)

(just my lack of experience in posters) :D

David Zaslavsky

I'd do it something like this:

or maybe with a white background

Crazy Buddy

you're fast :D

(nah... black is good.. it's nice..)

David Zaslavsky

well it's easy when there's not much to do, I just took the logos from the website and pasted them in

white version, just for reference

In any case, technically we should probably ask the astrobites people at least for permission to use their logo first, and perhaps they will even provide their own ad

Crazy Buddy

8:28 AM

@DavidZaslavsky Well, errr... Thanks for the poster. But, you can simply add yours inside the ads list ??? o.O

David Zaslavsky

Oh, I wouldn't add mine, the antialiasing in GIMP is pretty terrible

(look at the text at the bottom, see how blocky it is?)

Crazy Buddy

o_O

David Zaslavsky

(maybe it's not so clear in this image but it looks really bad when I'm editing it)

Plus there's that issue with getting permission

Crazy Buddy

@DavidZaslavsky Then, change of plan... No logo...

I'll add some other nice astro pic ;-)

David Zaslavsky

It's not the same without the official logo though ;-)

I think it's best if one of us just ask them on Monday

Crazy Buddy

8:31 AM

You or Chris..? - decide it yourselves...! :D

David Zaslavsky

yeah, we'll figure it out

I can try to get to them on Twitter perhaps

Crazy Buddy

(y) -- duh... doesn't work like facebook :)

Crazy Buddy

8:45 AM

both trials robbed 20 mins from me :)

David Zaslavsky

it's simple :-)

But that sentence "Can you actually believe that grads write for undergrads?"... I can't put my finger on why, but that feels very wrong.

I'd say don't use that.

Crazy Buddy

Oh my... Okay...

David Zaslavsky

In general, I'm not really a fan of using questions in a formal ad like this, but that's just me.

Crazy Buddy

David Zaslavsky

That's much better

I'd leave out the ellipsis

Crazy Buddy

8:51 AM

@DavidZaslavsky Err... elli... what..?

David Zaslavsky

the three dots at the end

Ellipsis

Ellipsis (plural ellipses; from the , élleipsis, "omission" or "") is a series of dots that usually indicate an intentional omission of a word, sentence or whole section from the original text being quoted, and though necessary for syntactical construction, is not necessary for comprehension. Ellipses can also be used to indicate an unfinished thought or, at the end of a sentence, a trailing off into silence (aposiopesis), example: "But I thought he was When placed at the beginning or end of a sentence, the ellipsis can also inspire a feeling of melancholy or longing. The ellipsis cal...

Since that's a sentence fragment on the ad, you don't need any punctuation at the end

Anyway, I should go to sleep probably

(it's 5 AM here)

Crazy Buddy

okay... so, today I've learned how to create an ad ...!

David Zaslavsky

kudos :-)

Crazy Buddy

@DavidZaslavsky Chris was right anyway... Grads don't sleep...

Gd n8 David ;-)

David Zaslavsky

Like I said, I'll contact them about permissions etc. on Monday

good night

Crazy Buddy

8:53 AM

Okay... Okay... Take your time...

@CrazyBuddy What I meant was that isn't having an "Type Ia Supernovae" thing there just like the "Atoms and Nuclei" thing?

Crazy Buddy

@dimension10 Ohh... you asked that... He just said that "Type 1a SN" wasn't necessary there. I actually hid the real message by asking such a question :)

Chem.SE isn't a daily journal or blog - it's just like us...

And, the ad says "Sounds like you've a question for nuclei and electrons.."

that's probably fine...

because, we're talking about Q&A site here...

@CrazyBuddy Why would anyone ask anything to nuclei and electrons ? : )

@ChrisWhite I actually learned about physymb from DZ (was a new member on this site, and I think I had brought up something about mathjax custom commands on meta)
