discuss why synchrotron sources of x-rays are important for physicists, biologists, archaeologists and others, as well as why Dolly Parton matters. You may be alive today because of vaccines based on MRNA, a molecule similar to DNA. In the 1950's Rosalind Franklin took x-ray data for 3 years to find the structure of DNA. Today that data could be taken in 15 minutes at the Canadian Light Source (CLS) in Saskatchewan. There's one in Canada, eight in the USA, and twenty in Europe. There are none in Africa and I will discuss our efforts to build an African Light Source (AfLS). https://www.africanlightsource.org/ My involvement has been in editing the proposal for the AfLS, growing out of my work on Commission 13 (Physics for Developing Countries) of IUPAP. https://iupap.org/who-we-are/internal-organization/commissions/c13-physics-for-development/ The Conceptual Design Report for the AfLS is 340 pages long, showing the depth of interest. A good exposition of the beam formation effect, but not suitable for lay audiences, or even for inclusion in a talk for physics students is: https://www.youtube.com/watch?v=FnYNjKabmxU
Michael Steinitz's research areas are in neutron scattering and dilatometry, as applied to magnetic structures of rare-earth and transition metals, especially incommensurate and density-wave structures. He has developed dilatometric methods for use at cryogenic and very high temperatures. Together with Jan Genossar of the Technion, he developed the tilted-plate capacitance displacement sensor, which allows angstrom resolution at temperatures exceeding 1000 C. Since Autumn of 2006 he has been the editor of the Canadian Journal of Physics.
