Quote: "There is a theory which states that if ever, for any reason, anyone discovers what exactly the Universe is for and why it is here it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened.”... Douglas Adams 1952 - 2001
"Carbon nanotubes—tiny cylinders made of carbon atoms—conduct heat hundreds of times better than today's detector coating materials. Nanotubes are also resistant to laser damage and, because of their texture and crystal properties, absorb light efficiently. Scientists hope that the nanotubes' resistance to aging and hardening will allow them to extend the range of NIST laser power standards to ultraviolet wavelengths."
