user116211

Dover is great ;)

Todd Minehardt

yeah, love them

user116211

Lanczos is also Dover.

Todd Minehardt

for about $100, you can get a pretty incredible bookshelf from Dover

user116211

@Rubisco, would you download the result, please?

user223679

@MAFIA36790 yes

user116211

@todd I have not seen an explicit discussion on Lagrange bracket other than in Lanczos so far.

@Rubisco some people were not following the rules...i asked to upvote for either "support" or "no support" for the policy...people started downvoting the support instead of upvoting the "not support" section

Phew, now I can continue not being a mod.

If there were 3 mods to be elected the third would have been you :-) @Rubisco

Rubisco

20:11

Being a mod bears some responsibility, and not saying some things.

I can hardly do that.

it would be learning curve

Rubisco

That's not what I meant.

I'm a jerk sometimes.

Mods aren't allowed to be jerks.

@MAFIA36790 Hello!

Rubisco

20:40

@ffahim It doesn't have a name, since we don't have Ch.

Bernard Meurer

I need to rant about Chemistry, have I come to the right place?

@Rubisco Thanks!

Rubisco

@BernardMeurer Precisely.

Bernard Meurer

[BEGIN RANT]

So, I'm a freshman in computer Engineering

and I disliked Chemistry throughout High School

user116211

@BernardMeurer I don't know how at the same moment, 0celo pinged me!!

Rubisco

AND THERE'S THIS STOOPID OCTET

Bernard Meurer

20:42

Actually, that's not fair

ffahim

Ch ! did u say that for not using capital letter?@Rubisco

Bernard Meurer

I liked Inorganic, I hated organic

Rubisco

@ffahim Yes. Correct capitalization matters.

user116211

It will be a mystery to me.

Bernard Meurer

Well I have Chemistry in my freshman course

Rubisco

20:42

@BernardMeurer Organic hates you too. He just told me.

Bernard Meurer

and, well

ffahim

Oh.... pls just tell me the answer@Rubisco

Bernard Meurer

THIS PROF IS BANANAS

user116211

@rubisco, I wrote a congratulatory post; why in the world would someone downvote it ;/

Bernard Meurer

The guy is doing triple integrals on spherical coordinates and we don't even know Calc I

Rubisco

20:43

@ffahim What do you think the answer is? I wanna see what you have a problem with. I don't want to do your homework for you.

Bernard Meurer

So everyone is on the brink of suicide, and there's an exam monday and I have no clue

Rubisco

Bernard Meurer

[END RANT]

user116211

@BernardMeurer REVOLT AGAINST THAT PROF.

Rubisco

@BernardMeurer -1 VLQ rant

Bernard Meurer

20:44

@Rubisco I've been stripped of emotions

user116211

@BernardMeurer This is simply nonsense.

Bernard Meurer

@MAFIA36790 Tell me about it, the man speaks Klingon

Rubisco

You should begin with insulting the person who invented octet and end with the person who discovered redox.

user116211

@BernardMeurer I knew it ;/

Bernard Meurer

but anyways

*exam saturday

user116211

20:44

@BernardMeurer Horror

ffahim

It's not homework what I was thinking that which should be considered first. CH3- or C2H5- ?@Rubisco

user116211

You should report against the prof for making such a crap syllabus @bernard.

Rubisco

@ffahim First in doing what? That's a methyl and the second is an ethyl.

Bernard Meurer

First of all, can anyone explain me what's the jazz with hybridization? Why is it that 2S and 2P do magic together and the other orbitals don't? Also, Why only 2Px and 2Py hybridate with 2S forming a $\sigma$ bond, while 2Pz forms a $\pi$ bond?

ffahim

Is it just because methyl is in the first row of functional group? @Rubisco

Rubisco

20:47

@BernardMeurer They don't do anything. That's the point.

Hybridization is something we made up.

It's mathematical, but doesn't happen in reality.

@ffahim You should draw trial structures and then start naming.

Don't throw wild guesses.

user116211

@bernard, dude you need a good book now to save yourself.

Bernard Meurer

@Rubisco So I'm learning lies?

user116211

@BernardMeurer no.

Rubisco

@BernardMeurer Not lies, but a model that makes explaining some stuff better.

user116211

It's an efficient method in Valence Bond Theory.

Bernard Meurer

20:49

Hm. Bloody chemists

user116211

You don't need it in MOT.

Rubisco

@BernardMeurer Once you read good chemistry material, you'll start to love it.

ffahim

I am just confused whether to consider CH3- belongs to second carbon or 4th carbon @Rubisco

Bernard Meurer

@Rubisco The only good thing about Chemistry is I get to play with the spectrometer in the lab

Rubisco

@ffahim Tip; the ones in the parentheses are not from the main chain.

Bernard Meurer

20:50

Also hexane smells funny

That's nice too I guess

Rubisco

You should REALLY get something good to read.

Niceness isn't just something chemistry.

It's the science that's nice to play with. Chem is part of it.

ffahim

Is it Ch3-CH2- ?@Rubisco

Rubisco

If taught well.

Bernard Meurer

@Rubisco What's a good book then?

Rubisco

@BernardMeurer I have no idea what your level is.

But consider taking a look at our 'Resources for learning chem'.

Bernard Meurer

20:52

And idk what you're talking about the spectrometer spins like a carousel it's very fun

user116211

@BernardMeurer What are you learning basically? Which topic specifically?

ffahim

Oh pls tell me @Rubisco .....

Bernard Meurer

@Rubisco Freshmen course taught by a madman that resembles an oompa loompa

That's my level

Q: Resources for learning Chemistry

Based on various other Stack exchange site (Mandarin Chinese, Russian and German), we adapt this project here for chemistry, since it's a great idea to have all kinds of resources in one place. This is a specifically created Community Wiki which gathers resources for learning Chemistry. The list...

software reference-request books

Bernard Meurer

@MAFIA36790 Bonds right now. We have to make these funny diagrams

Rubisco

20:53

@ffahim I have no idea what you're referring to, but if it's a side chain, it won't be that.

Bernard Meurer

It's a general chem course supposedly

Rubisco

OK, gotta sleep

Night all

Bernard Meurer

@Rubisco Goodnight! Thanks for the reference!

@Rubisco Nighty night @BernardMeurer you should try the NCERT textbooks...they are awesome for basic CHEM

i read it

Bernard Meurer

I'm willing to bet my prof doesn't have it lol

Let me try to buy it somewhere that isn't 300 dollars

orthocresol

Atkins is inaccessible to beginners

user116211

21:01

@BernardMeurer Your prof will destroy you someday, I warn T__T

orthocresol

Not only my opinion- many people say the same

user116211

I then have to differ.

Anonymous

@orthocresol yeah i tried it in 11 standard....some things were really given in a convoluted manner...i left it and bought some video lectures

user116211

It's not an extraordinary book; but pretty accessible and useful to undergrads.

Bernard Meurer

@MAFIA36790 That day is saturday on my exam

user116211

21:02

:(

Bernard Meurer

Okay, @MAFIA36790 Do you know how to do bond diagrams

user116211

@BernardMeurer like?

@MAFIA36790 It really depends whether you have previous exposure to Chem before undergrad...its not for noobs :-) "Peter"

@BernardMeurer reading it?

orthocresol

Obviously it depends on the user and their own style of learning, but most people I know did not like Atkins.

user116211

21:28

Sure @orthocresol, I respect their and your opinion; but I can 't say anything more.

orthocresol

@MAFIA36790 Of course, you are entitled to like it as well :)

But I am a mod, so I think my opinion should be far superior to yours.
