@Loong Why did you suggest something only to delete it twelve seconds later?

Loong

@Jan It's still a draft. I don't want the users start to vote on this proposal until it's finalized what I am actually proposing here. However, I need to post it somewhere so that the other mods can have a look.

Jan

That makes sense, I guess.

Loong

I mainly try to write down, what we started to discuss here:

13 hours ago, by Loong

To correctly organize the related (and often confused) branches of chemistry, we would need radiochemistry, nuclear-chemistry, and radiation-chemistry.

When the post is ready, I can simply undelete it and you may start voting and commenting as usual.

Nevertheless, if you already have another idea or comment about this, feel free to tell us. You dont have to wait for my post. :-)

Jan

No, not really ^^

Loong

I guess it looks like the expanded version of what you already proposed in your question.

Q: Why doesn't curie temperature follow a periodic trend in ferromagnetic materials

I was writing up an answer to a question which was asking why the Curie Temperature's of $\ce{Fe, Co, Ni}$ don't follow a periodic trend. The OP voluntarily deleted his question before I could finish and post my answer. The OP has reasoned as follows: Since Iron, Cobal and Nickel have electron c...

Hi, everyone :-) I have a quick question about charge delocalization.

user228700

user228700

It seems that the larger the number of $\alpha$ hydrogen atoms, the more stable the structure is. I realize that a larger number of $\alpha$ hydrogen atoms corresponds to a higher charge density on the ring but why does this increase the stability of the compound?

user228700

Nvm.

@Jan I was hoping it was something by you. Eh, I forgot to remind you to bounty your Wittig question. However, given that there is a hat for awarding a bounty on the last day of Winterbash, you may want to wait until New Year's Day.

By the way, what hat is that?

The bowler hat-monocle combo you're wearing @Loong?

Loong

That's Like Clockwork, i.e. the hat from A Clockwork Orange.

@MelanieShebel thanks to you I have my best liked answer. So next time please ask anothoer random question which is not about chemistry :)

@Loong or @orthocresol or @Jan or who have the answer, why the links for the chats disseapeared one my screen ? Before there were between Favourite tags and HNQ.

Yes, in my experience those aren't always there.

It makes zero sense for resonance to be "fast" or "slow". Anyway, I don't want to answer this.

In the next few months I'm not going to have much time to answer questions anyway.

Q: A drop of water in a tin of sugar... which one's the solvent?

The other day, when we were dealing with the chapter Solutions, our teacher asked us this: If I add a drop of water, to a tin full of sugar, what's the solvent here? The water or the sugar? Naturally we were taken aback by the 'unorthodox' nature of the question. Seeing that none of us were...

Why are there so many shitty questions on the main page now?

Jan

@DHMO Quite a few, actually. Mostly because they could crystallise transition state mimicks.

@orthocresol Maybe next time. At the moment, I’m writing a lot of answers that don’t require ChemDraw elaboration because I’m far away from my ChemDraw (and will be for another week and a half).

Question regarding Academia more than chemistry, but would rather ask it in chem chat than Academia.se

So I want to apply to University of Pittsburgh in a year, or really attend grad school in general, for chemistry.

I'm a member of the honors program at my college and it's been a really rough time. Essentially, there are five main things I've dealt with.

1.) The honors college held a research conference and I did REALLY well with one judge (49/50) and really poorly with another. This other judge cited that "the group had a lot of energy and something about the study of arachnids." I was solo and did not study arachnids, so this was not my score, but rather the score of another poster. A professor was upset about unfairness in her students judging and so when she heard about how I was judged, she lumped us together in a complaint, but they found no wrong doing and told us to suck it up.

Okay, so that's everything... all lumped into one... not five things, haha!

Anyway, my question is this:

I'm really, really gutted about it. Even still. This was last Spring and it's just hard to do research. I work so incredibly hard and I used to get so much joy just out of doing my work. I didn't really need recognition or anything. I would write code to do a thing and sometimes it would just work and things would piece together and I would feel SO great about it. But anymore I'm just so depressed and demotivated. I've talked about it until I'm blue in the face, but I don't know how to feel okay about it.

I'm going to go ahead and ask this on Academia.se. Good talk.

Melanie Shebel

23:31

I posted it on Academia.SE. If anyone can think of a better title for it, let me know. I hope it's appropriate for me to post the link here.

I'm an undergrad in chemistry and am in the honors college at my school. Here are the two main things that happened surrounding my research: Last Spring, the college held a research conference and I did REALLY well with one judge (49/50) and really poorly with another. This other judge cited t...

I have to run, but that isn't how everything is. We would love to have motivated students of any caliber...most simply aren't.

Generally honors college type people can go pound sand.

Ooooh, an answer with a –1 score. Should I get my hopes high for peer pressure? =D

Yes.

I’m confused. Did I go wrong while watching anime? Gotta look back at it later.

Melanie Shebel

I'm kidding. :P
