April 10, 2019Madame Curie and the Curie family, presented by Charlie Holbrow. Madame Curie and the Curie family will focus on her and her daughter and their characters and discoveries and how they fit into the sequence of dramatic developments in physics between the discovery of radioactivity in 1897 and the discovery of nuclear fission in 1938. This will include some description of Lise Meitner's role in these developments and a brief mention of why she didn't get a Nobel for the discovery of nuclear fission.

Work in progress/upcoming

Charlie Holbrow's next two talks:
#2 What quantum mechanics says about the material world and about measurement;
#3 what of its properties make quantum theory of so much interest to cryptographers on whose work all secure data exchange and storage fundamental to individual privacy and national security now rely.
He says “My goal is to explain some basic quantum ideas that you need to understand quantum computing. Part I is about particles, waves, coherence, interference, and complementarity. Parts II and III are about quantum states, entanglement, no-cloning, quantum correlations, non-locality, Bell's theorem, and local realism.”
