The same process that determines why certain bees become queen bees while others with the exact same DNA become worker bees also plays a role in how doughnuts eaten by a pregnant woman may influence whether her child becomes obese.
Having the knowledge and understanding of scientific concepts and processes necessary to make informed decisions on scientific issues.
When astronomer Isaac Roberts showed a photograph of the Andromeda Nebula to the Royal Astronomical Society, it caused a huge sensation. “There were audible gasps in the audience,” astronomer Alan Hirshfeld told the audience at the first Ronald E. Hatcher Science on Saturday lecture at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory on Jan. 9.
“The professional astronomers had never seen such a clear image of the nebula,” Hirshfeld said.
This presentation will provide a physicist’s perspective on a proton therapy for cancer treatment. It will include a context of how radiation therapy fits into cancer management overall with an emphasis on the differences between proton and conventional radiation therapy. Additionally, new developments in proton therapy including spot scanning, range verification approaches, and gel spacers will be presented.
***ATTENTION*** Join us as Dr. Ondrechen gives her talk at our final lecture of the series on March 19, 2016- same time, same place!
Quantum mechanics based computer simulations can help provide insights into the survivability of first wall and divertor materials. I will present results of research aimed at assessing how hydrogen isotopes interact with solid tungsten and liquid lithium, candidates for plasma facing components of fusion reactors. An overview of Princeton University's Andlinger Center for Energy and the Environment will also be provided.
After detonating the first nuclear weapons in Japan, to devastating effects, the U.S. government turned swiftly to promoting the peaceable dividends of atomic energy. The first such benefit took the form of radioactive isotopes, produced in a former Manhattan Project reactor and distributed to civilian purchasers beginning in 1946. The consequences of this new supply of radioisotopes for science and medicine were profound and extensive, as illustrated by developments in biochemistry, nuclear medicine, and ecology.
Earth's 4.5 billion year history is a complex tale of deterministic physical and chemical processes, as well as 'frozen accidents'. Most models of life's origins also invoke chance and necessity. Recent research adds two important insights to this discussion. First, chance versus necessity is an inherently false dichotomy--a range of probabilities exists for many natural events. Second, given the astonishing combinatorial chemical richness of early Earth, events that are extremely rare may, nevertheless, be deterministic on time scales of a billion years.
