Quote for the day,

"Whatever may be one's opinion as to the simplicity of either the laws or the material structures of Nature, there can be no question that the possessors of such conviction have a real advantage in the race for physical discovery. Doubtless, there are many simple connections still to be discovered, and he who has a strong conviction of the existence of these simple connections is much more likely to find them than he who is not at all sure that they are there." - Percy Bridgeman

Nanotech news extra,

Direct Laser Writing of 3D Architectures of Aligned Carbon Nanotubes . I recall an arxiv article about making a nanomachine that can pick and place single atoms.  This was so many years ago; I wasn't even trying to keep track of new developments back then.  Still, assuming that arxiv article was correct and this laser writing of nanotubes works, we should be able to 3d print nanomanufacturing systems right now. I tried to contact one of the engineers of this article, but I haven't gotten any reply!  Oh well . . .
