Our guest this week is the luminous Prof. Jo Dunkley of Princeton's Departments of Physics and Astrophysical Sciences, who just published her first book, Our Universe: An Astronomer's Guide. Jo boils down our universe's 13 billion year history into a digestible story, traveling from planets to stars to clumps of dark matter on the way. She reminds us of the painstaking research that enables our modern understanding: for example, female "computers" like Henrietta Swan Leavitt in the early 20th century made crucial discoveries about stars and distance even as male scientists monopolized the telescopes. Finally, Jo explains the radical idea of measuring gravity by looking at distortions in the cosmic microwave background, a primary thrust of her current research.
