The NXS Class of 2014

by Kathy Chambers 19 Nov, 2014 in

Every summer for the past 16 years, the Department of Energy has invited the best and brightest graduates from across the country to attend the National School on Neutron and X-ray Scattering (NXS). This year, 65 graduate students attending North American universities, and studying physics, chemistry, materials science, or related fields, participated in the 14-day whirlwind emersion into national user facilities to learn in a hands-on environment how to use neutrons and X-rays in their research.  This educational program is jointly conducted by Argonne National Laboratory's Advanced Photon Source and Materials Science Division and Oak Ridge National Laboratory's Neutron Scattering Science Division.

The Reverend Thomas Bayes

Thomas Bayes

During the 1700’s, the Reverend Thomas Bayes was a nonconformist minister at the Mount Sion Chapel in Tunbridge Wells, UK, about 40 miles southeast of central London.  Having studied both theology and logic at the University of Edinburgh, he was also a mathematician and developed a strong interest in probability late in life. He was known to have published only one book on theology and one book on mathematics in his lifetime. A third manuscript he never published about the probability of cause made him famous. After his death, a good friend Richard Price recognized the importance of the paper and, after extensive editing, submitted it for publication. More than 20 years later, the great French mathematician, Pierre-Simon Laplace devised the formula for Bayes’ probability of causes and acknowledged Bayes as the discoverer of what we now know as Bayesian inference.
