Welcome to the Universe – The Problem Book

"This book provides a very valuable resource for anyone who wants to acquire a reasonably quantitative understanding of introductory astronomy. The questions cover a broad range of interesting topics, and the solutions are thorough and often enlightening, providing additional insights into the subject matter."--Alex Filippenko, University of California, Berkeley

"The difference between a good astronomy course and a great astronomy course is great problems. This book is a gold mine of great problems for introductory astronomy, problems that can be solved with high school algebra and run the gamut from earth-smashing asteroids to neutron stars, black holes, the fate of the universe, and the search for life on other worlds. It will be a valuable resource for anyone teaching introductory astronomy and an exhilarating challenge for students who want to sharpen their wits against the cosmos."--David Weinberg, Ohio State University

"A fantastic asset. The hardest part of teaching introductory astronomy courses is writing engaging, informative problems at the appropriate level. This book provides a treasure trove of wonderfully instructive material that is much better than anything else out there. I will be using Tyson, Strauss, and Gott for a long time to come."--James H. Applegate, Columbia University

"A marvelous compendium. This companion book demonstrates in a playful manner how, with no more than high school algebra, we can obtain a deeper appreciation of the properties of the infinitely large and small, and deepen our conversation with the cosmos."--Trinh X. Thuan, University of Virginia

"A wonderful collection of introductory problems that convey the wonders of the universe and fundamental concepts in astronomy through specific examples and numbers. A fantastic resource for the classroom and aspiring astronomers."--Abraham Loeb, Harvard University

"Microorganisms on Europa, colliding black holes, cosmic inflation, and much more are covered in this expansive and thoughtfully selected collection of exciting problems in astrophysics--even a two-dimensional Tardis appears! Both students and experienced astronomers should come away enriched through study of these problems and the techniques presented to crack them."--W. Niel Brandt, Pennsylvania State University
