Carl Woese

Not long after Carl Woese died, I received a message from Robin Gutell asking if I would contribute an article to this issue of RNA Biology. While my admiration for Carl's contributions to biology knows no bounds, I did not know him well personally. For that reason I advised Robin to strike my name off the list of contributors and replace it with that of someone who is better qualified than I a...

The Born-Oppenheimer Approximation

where R is the set of nuclear coordinates and r is the set of electronic coordinates. If spin-orbit effects are important, they can be added through a spin-orbit operator Ĥso. Unfortunately, the V̂eN(r,R) term prevents us from separating Ĥ into nuclear and electronic parts, which would allow us to write the molecular wavefunction as a product of nuclear and electronic terms, Ψ(r,R) = Ψ(r)χ(R). W...

Carl J. Carl J. Levinson, MD, 1927–2011

With such a mentor, we are pushed to become much more than we could have been, to strive to achieve beyond ourselves. Carl exemplified this in his character not only for SLS and me but also in other organizations and places, such as AAGL, in Milwaukee, at Baylor, in San Francisco, and ultimately at Stanford. He influenced many leaders in the field today. To name just a few: Camran Nezhat, Rober...
