Wow, @Ortho Ont you fixed one of my earliest posts. I was an immature idiot back then
I'm a mature idiot now

Q: breaking of the epoxide bond

anilinei am facing trouble in the following problem. The product $A$ and $B$ respectively in the following reaction is I have the following options to choose from In my view since $\ce{HN_3}$ is more strong nucleophile than $\ce{NH_3}$ so B should form via SN2 mechanism .so cleavage should take...

Q: Strength of pi bonds and sigma bonds?

Pranav I know that sigma bonds are stronger than pi bonds. What I am confused over is the strengths of the pi and sigma bonds formed between different orbitals. In class, our sir told us that $p\pi - p\pi$ bonds are weaker than $p\pi-d\pi$ bonds. The reasoning he gave behind this was that since the d o...

 
6 messages moved to Trash
 
@orthocresol Can u pls help me?
@orthocresol ??
 
6:12 PM
@Pranav Those messages were redundant
So he moved them
BTW, @Ortho dunno if you know, but there's a Trash room especially for mods
 
!!beer
 
@M.A.R. I do.
 
Here's to the trash room :D
 
It's helpfully named something different from Trash.
:)
 
6:19 PM
@orthocresol Crashtan
 
I thought it was Cashtran.
Whatever, it's something along those lines.
 
@M.A.R. Please don't throw old mods in the trash!
 
@Loong We have no other alternatives. Don't worry. They will regularly be renewed.
 
mod recycling?
 
@Loong You can think of them as Litmus papers
Oh no

Q: MathJax site going offline

robjohnThe news that MathJax CDN shutting down on April 30, 2017 was recently brought to my attention. I am testing an updated version of ChatJax which uses the alternate server given in the MathJax post. It seems to work well, but if StackExchange is going to host a local copy to use with the sites t...

 
6:24 PM
:-O
 
That's extremely disappointing.
 
We don't know yet. We are going to talk it over in our next team meeting. This is not super urgent, in that there's still to the end of the month to deal with it. Don't worry - we will make sure MathJax is still supported on the sites it is enabled on. — Oded ♦ 2 mins ago
 
@pentavalentcarbon Robjohn's avatar is apt right now
 
He is the original mean square.
 
stupid unrelated question: is there a StackOverflow chat room? I can't seem to find one.
 
6:27 PM
zzz
 
I see what you did there
 
http://chat.stackoverflow.com/
I pasted that url and it linked to SO main page instead
 
That's what I get for searching on chat.stackexchange.com
oh, I thought you were being snarky and implying their main page might as well be chat-quality
 
You really assume the worst of me, don't you?
 
@penta there are three main chat servers
 
6:29 PM
anyway, the chat system is set up such that meta.SE chat, SO chat, and remainder-of-SE-chat is separate
 
Chat.SE, chat.SO and chat.meta.SE
 
I had absolutely no idea
 
@orthocresol Jinx
@pentavalentcarbon Now you have little to much idea
 
@M.A.R. haha... it took me a really long time to figure out where chat.meta.se was...
 
Anyone knows how to buy products from alfa aesar as an individual ?
 
6:30 PM
 
@M.A.R. SEE WHAT I MEAN
 
Bah
Stupid
 
Proof
 
https://chat.meta.stackexchange.com/
I've been a regular in two of its rooms for two years
Did you also know some rooms don't have a parent chat associated?
 
As if that's not confusing enough,
Yeah, precisely. Those.
UGH
 
6:32 PM
Those are rooms in 'the SE network'
 
Like Sandbox
No chat parent means the tag syntax won't work there
[tag:blah-blah] I mean
And all rooms currently being created need a parent chat room, and only a mod can change it or set it to no parent chatrooms
Mods of each server are separate @Penta
Which means Ortho has no power in SO rooms.
>:D
 
ugh, I posted a message in an SO room, now I feel dirty
 
!!flip/>:D
 
(۶ૈ‡▼益▼)۶⅋ƃʇ؛:ᗡ
 
6:35 PM
Chat.SO mods are SO mods, chat.SE mods are SE mods, and chat.meta.SE mods are SE staff
 
and a partridge in a pair tree
 
6:49 PM
@M.A.R. I hardly exercise my power outside of chemistry anyway
 
@orthocresol But it's really soothing to know you're not a mod there !!untable
 
┬━┬ ノ( ゜-゜ノ)
 
Shog is a mod everywhere.
 
@skullpetrol Shog is Shog.
 
and a blog is a blog

This lab is driving me nuts. chemistry.stackexchange.com/q/71722/402
 
@Melanie Shebel Your chromatography question is an interesting extension of the observation of $\beta$ fronts.
(in case you have a binary solvent system), or $\gamma$ fronts, if you run a chromatography with a tenary system of solvents.
 
@M.A.R. eeeee... not April Fool's, I guess... :-/
 
On the other hand, wouldn't it reverse the role of eluent and analyte?
 
9:18 PM
I just didn't know the terms beta or gamma here
or ternary
Sorry @Buttonwood :S
 
9:31 PM
You got a notice, in reply to the coffee / soda analysis
Your assumption is correct
(The publication has other examples, too, side-by-side).
Regarding $\beta$ and $\gamma$-fronts in TLC (chromatography wise), I learnt about them much after the first contact with chromatography in a lecture.
Rather astonished, once, to have something like "two fronts" on my TLC -- revealed after staining with this anisaldehyde "dip",
one "as textbook requests" very horizontal / parallel to the cut, and the second like an open / dropped jaw.
Maybe an example "what the instructor wasn't telling, but the TA ..."
 
@M.A.R. Missed some spots in that edit
 
9:52 PM
@Melanie Shebel I was courious to look at your profile page, and as it led to your poster posted on twitter -- still legible at this distance / low resolution -- the "better posters" blog came into my mind. It looks like you might be interested to follow this page, too: betterposters.blogspot.de Weekly, there is one review, so traffic is not enormous.
 
10:02 PM
What do you mean, @Buttonwood about the poster
 
There is structure, guiding the eye.
The fonts are legible.
So even if one is not terrible close to the poster gets an idea.
The Ramachandran plot is still in my memory, despite the twitter page is not accessed for about 2 or 3 min.
 
Oh, thank you
 
As well as the blue dot diagram in the second column, lower part.
Maybe a "heat diagram" if it were colour-coded, but it is not, the diameter of the dots was the third dimension introduced / conveyed by the diagram.
Sometimes, poster presenters have much to tell and aim to bring all into the poster.
 
Yeah, I so very much wanted it to be a heat diagram.
 
But a poster is not about squeezing the multipage publication into this format;
rather than providing "enough appetite" to come down the aisle, and to initiate the poster talk.
 
10:08 PM
Unfortunately, the numbers were discreet and I feel like learning R would have helped.
 
Ha... R.
(No offense against R).
 
Lol
No worries.
Those six graphs were one of the most time consuming parts of the project.
 
I'm just starting to get some grip in R, so a "bloody beginner"...
 
That and babysitting 100,000+ files when a server isn't working properly!
I hope someday to know enough programming to do computational. I was thinking of doing some research work in it... like something more programming heavy.
 
What about joining a local R user group?
 
10:11 PM
Speaking of which, I need to get in contact with Hutchison about potentially working in his lab.
I live in a cornfield.
 
Could be romantic ...
 
There's this saying, "There's more than corn in Indiana."
Which is true, we have corn syrup refineries.
But alas, no billboards touting "Come to our local R user group," on the side of the road.
Honestly, if I passed such a sign anywhere, I would be like, "Let's look into some local real estate!"
 
I thought something like R could be topic at colleges and universities.
 
A couple of people who came to my poster mentioned R. Mostly the questions were, "What do you program in?" And then followed by, "Have you thought about Python?"
 
I heard by physicists about Python, too.
and mathplot lib (or similar), too.
 
10:15 PM
Yeah, it really seems to be the direction that programming in science is going in.
Not just per this post:

Q: Why is FORTRAN so commonly used in computational chemistry?

Melanie ShebelI've been using Ruby to write scripts for research, but I want to get into some heavier stuff that Ruby is just too slow for. I noticed there are a few things written in C and C++, but there is an oddly large proportion of software used in computational chemistry that is written in FORTRAN (in wh...

 
"They" are so much more into programming, apparenltly, since their start in study.
Good old Fortran ... my first contact with programming in French school ...
I think part of an answer for Fortran -- beside its age, and ongoing development -- are publications like "numerical recepies in Fortran"
There is an other volume I know about, too; "numerical recipes in pascal", again with the subtitle "The Art of Scientific Computing"
Cambridge Press, (UK).
I agree with your observation, chemistry turns more and more into / toward computation and IT in general.
Including inorganic chemistry / chemical engineering.
John Kitchin @Carnegie Mellon is one example.
From his preferred editor Emacs, he is able to collect literature references, to collect articles and their references, to write papers and teaching material ...
including running codes in python -- the following link is a bit longer (21 min):
Your question about FORTRAN / Fortran is interesting; both the question addressed, as well as the answers provided.
It is true, some software will remain "alive" as long as there are (still) people around who know not only about the algorithms, but their implementation in this very language.
In terms of single crystal diffraction analysis, just to mention George Sheldrick's Shelx suite -- even if Bruker backs it / commercializes it in a slightly different form.
Or Platon, an other software in this field; basicially to check for consistency and errors in the data eventually brought together about the diffraction experiment, the *.cif file -- even more troublesome, as there is only Tom Speck who knows the software this well and maintains it.
So it is indeed a valid point to watch out for a language that is "widely spoken" today, with a good chance to be alive in the years to come.
