"Table top" science is great.
But how about "table top" nuclear technology?
On the Back Page of the APS News there is an important debate about The Benefits and Risks of Laser Isotope Separation. The science is really interesting, but the prospect of being able to make enriched uranium with a "table top" facility is scary.
I felt Mark Raizen's view that "this will only work for light atoms so we don't have to worry about complex atoms like uranium" is a little naive given the history of science.
