2Physics Quote:
"Stars with a mass of more than about 8 times the solar mass usually end in a supernova explosion. Before and during this explosion new elements, stable and radioactive, are formed by nuclear reactions and a large fraction of their mass is ejected with high velocities into the surrounding space. Most of the new elements are in the mass range until Fe, because there the nuclear binding energies are the largest. If such an explosion happens close to the sun it can be expected that part of the debris might enter the solar system and therefore should leave a signature on the planets and their moons." -- Thomas Faestermann, Gunther Korschinek (Read Full Article: "Recent Supernova Debris on the Moon" )

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!
