Enjoy Our Universe is a guide for an enjoyable visit to the Universe. The "Universe" refers to all "observable things," ranging in size from the entire cosmos to elementary particles. This small tome on fundamental physics, cosmology, Higgs bosons, time travel and all that, is unlike any other analogous book. Its scientific statements are correct or, at least, they coincide with the opinions held by the vast majority of experts. It establishes clear distinctions between things we know for sure -- in the sense of having strong observational support for them -- and things that we know that we do not know, or we do not understand. In this sense, it is scientifically honest.In descriptions of our Universe and of the way it functions, beauty is a recurring word. In an attempt to portray its beauty from the eyes of the beholder, the book is profusely illustrated. Its offbeat, tongue-in-cheek illustrations greatly enhance its readability, particularly in those chapters whose understanding, admittedly, requires a little extra effort. This book's idiosyncracies remind us of our own smallness and eccentricities even as we read about the logic, function and magnificence of the Universe.
