@LordStryker It is! Language is a bit of a problem, but hey... no risk no fun.

@Martin huge risk = great fun? Time to move to north korea! :)

Fun is probably not a monotonically increasing function of risk, even if there is a linear range

@NicolauSakerNeto Source?

Nicolau Saker Neto

Common sense

One would hope

LordStryker

@NicolauSakerNeto There is nothing common-sensical about your statement "Fun is probably not a monotonically increasing function of risk, even if there is a linear range". I mean... who even says things like this?

Not common at all :P

Nicolau Saker Neto

I just formalized it, the general sentiment is common sense!

LordStryker

Its sad, I just spent the last hour trying to figure out if a 'rock' was a 'molecule'

@NicolauSakerNeto What if you were a masochist?

more risk = exponential increase in fun

Nicolau Saker Neto

Well, at least I added "probably" to deal with such pathological cases!

(Pathological as in mathematically pathological)

@NicolauSakerNeto thats called hedging. Nobody likes hedging. :P

Nicolau Saker Neto

PROBABLY nobody likes hedging

@NicolauSakerNeto So what do you think? Is a rock a molecule?

Nicolau Saker Neto

I dunno, depends on your definitions of rock and molecule

I would say it's somewhat hard to defend

Looking up the IUPAC definition, it actually is quite broad

For molecule, that is

"Molecular entity" seems to be the IUPAC term for what we would generally consider molecules

goldbook.iupac.org/M03986.html

The part about "separately distinguishable entity" may limit its use for extended solids

Hah this is pretty neat goldbook.iupac.org/goldify.py

Copypaste the introduction for an article/thesis, see if the terms are being used properly

Molecule "covalently bonded atoms"

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

@NicolauSakerNeto That won't work for typset manuscripts. :)

Nicolau Saker Neto

Well there are many covalent polymeric extended solids

Though most rocks are largely ionic due to the high oxide content

Well, actually now that I think of it, silicon oxide is covalent

Q: What is the canonical way of scaling pictures?

I often find myself in the situation that I have to resize pictures that are part of my answer or question. My current workflow is that I upload the picture via the usual method and then copy the URL of the uploaded picture into the following html snippet, <img src="http://i.stack.imgur.com/image...

Q: 'bond' and 'bonding' tags - is there a reason for keeping both of them?

Presently, there are two bond-tags: 'bond' and 'bonding'. Both seem to be pretty much equivalent to me. The 'bond' tag has a description and is used more frequently while the 'bonding' tag lacks a description. I suggest that both tags should be merged.
