"About 200 femtoseconds after you started reading this line, the first step in actually seeing it took place. In the very first step of vision, the retinal chromophores in the rhodopsin proteins in your eyes were photo-excited and then driven through a conical intersection to form a trans isomer [1]. The conical intersection is the crucial part of the machinery that allows such ultrafast energy flow. Conical intersections (CIs) are the crossing points between two or more potential energy surfaces."

Nanotechnology: "There's Plenty of Room at the Bottom"

In 1959, Richard Feynman gave his visionary talk entitled "There's Plenty
of Room at the Bottom" on the Caltech campus in Pasadena, CA. This great
presentation by Feynman now holds a preeminent, defining, and inspirational
place in the history of the now-emerging field of Nanotechnology. In what
were approximately 7000 words, he mapped out potentialities that are only
today beginning to be realized.

In January 2001, President Clinton visited the Caltech campus and, in a
preview of his upcoming State of the Union address, announced his
administration's launch of the "National Nanotechnology Initiative." This
impetus has since led to a huge upsurge of activity; a number of major
universities and research institutions have now embarked upon their own
"nano" initiatives in diverse areas of nanoscale science and technology
that covers important areas of biotechnology too.

Caltech launched the Kavli Nanoscience Institute (KNI) in order to enhance
its multidisciplinary research activities in all ares of nanoscience. To know
more about nanotechnology, visit KNI website. Yes, you will get a link to
many interesting and popular articles about this field, including that
celebrated article by Feynman also!
