Re: 1924: "Solar Panels"

Is there any particular reason why this solution should be exclusive to solar roads? No. Concrete and brick pavers are used for roads in some places , but generally for aesthetics; historically, they've usually been more expensive because they're generally laid by hand. That said, you can now get p...

Re: 1431: Marriage

That's not so obvious. I've head that (in France at least) "Mariage" was religious first (catholic, to be precise), current civil laws just provided legal ground. It's not surprising as in the past, religion provided rules, and civil laws appeared later when state and religion separated. ...

Re: 1431: Marriage

Well, that's the point: using different names for the two different things (civil union vs marriage) seems like a good way to avoid maintaining confusion in peoples' minds. Good, which religious denomination gets marriage then? Because we would not want people to be confused between the different r...

Re: 1431: Marriage

I may as well interject. As someone who believes marriage is a holy institution between a man and a woman established by God (for life I might add, I feel as strongly about divorce as I do homosexuality), I can't reconcile gay marriage with my beliefs. However, I do believe that a distinction betwe...

Re: 1379: "4.5 Degrees"

... Well there you put it in a nutshell. AGW is really bad at what is actually happening, it doesn't describe reality. Even the model outputs diverge so much that it is hard to know if you couldn't just use dice-rolls instead of temperature measurements to produce similar predictions. That's not a ...

Re: 1229:Screensaver

This reminded me of a throwaway scene in Pratchett's Only you can save mankind . Where one of the characters (a kid) had programmed a real time simulation of a trip to Alpha centauri. But apparently that took even longer than 20 years. http://en.wikipedia.org/wiki/Only_You_Can_Save_Mankind

Re: 1047: "Approximations"

The gas constant is expressed in J/gmol.K and not J/kgmol.K which would be the SI unit. I've never seen the abbreviations "gmol" or "kgmol", but the SI units of the gas constant are Joules per mole Kelvin, and moles are defined as if they were based on grams instead of kg. Proba...

Re: Calling all scientists: Do you understand math?

While I am familiar with the Sigma notation for summations I cannot recall ever encountering the Pi notation for multiplications. I would have had to look it up or get it from context if encountered in the wild.

Re: Things that don't move shouldn't be considered alive

@Interactive Civilian, I don't think I'm especially knowledgeable in this area. I'm a molecular biologist, but I don't really do any work directly related to evolution. So please don't look at my thoughts as anything more than that. I agree that there's value in Dawkins' metaphor. I just worry that...

Re: Glass fragments reassembling themselves by chance

Atoms in bulk glass are distributed differently from the atoms in the surface layer, on breaking the glass the atoms at the new surfaces are re-distributed. This would have to be reversed in spontaneous reassembly, which probably makes spontaneous re-assembly orders of magnitude more unlikely than a...

Re: Places that refuse to use IUPAC nomenclature...

I use non-IUPAC names all the time myself. Half the time because it is a nice short-hand, half the time because it gives some nice variation.
The f/ph thing is more irritating, but that has more to do with preferred spelling (mine is a mix-and-pick from UK and USA) than with chemistry.

Re: Peptide conformation

High ionic strength shields charges on the lysine residues.
The Valine-Lysine repeat should be prone to form beta-sheets, the proline-glycine/gutamic acid can easily form a turn.
I'd expect a hairpin turn with the KV repeats folded back on each other to form a (anti-parallel) beta-sheet.
