Robert Schwartz spent the first half of his professional life as a philosopher and theoretical physicist, and is now a (not very) “old country doctor,” practicing medicine in Vermont. In QUASARS, BLACK HOLES, AND TIME TRAVEL he presents ten lavishly illustrated essays on cosmology, written in completely nontechnical language. What’s a Higgs particle, anyway? A radio galaxy? Spacetime? Dark energy? What are our best current tools of exploration—and what do they have to do with the tools the ancients once used? If you’re smart enough to talk to your family doctor, you’re smart enough to be thrilled by this look at our universe, what we know, and how we know it. Expected publication late 2017.
