That's good!
Was the Earth flat during the Planeocine Era?

Now we know what happened to the dinosaurs - they fell off the edge.

I feel like this questions not thread worthy so i'll post it here. When people talk about acid concentration in % i.e. 98% sulphuric acid, how do you work out it's conc in mol dm3?
Hmmm... technically moonlight is reflected sunlight, but does it contain enough UV to start the reaction? Lol, where's a chemist when ya need one...

That sounds ok moo.. the moon is thousands of times dimmer than the sun and over a much thinner spectrum. So there is either not enough intensity to overcome the backwards reaction or the wrong wavelengths present.

Einstein said that if quantum mechanics is right, then the world is crazy. Well, Einstein was right. The world is crazy.

I would expect there to be a 'critical frequency' situation is this free radical halogenation process.
I mean that the photons having energies above a specific limit will succeed in splitting the chlorine molecules.
This means that it will be wavelength rather than intensity that determines wether the reaction goes or not. For the moon, it might be very slow, but it might happen.
But then, does the moonlight have the required frequencies? It does reflect whitish, so I'd expect it to reflect UV also. Dunno.
How come we don't have "free moderates"?
... or "wavewidth"?

Astronomical instruments needed to answer crucial questions, such as the search for Earth-like planets or the way the Universe expands, have come a step closer with the first demonstration at the telescope of a new calibration system for precise spectrographs. The method uses a Nobel Prize-winning technology called a 'laser frequency comb', and is published in this week's issue of Science. Read » | 0 comments
Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers. The result is an autonomous helicopter than can perform a complete airshow of complex tricks on its own. Read » | 0 comments
