Why Is Uranus Upside Down?

Have you ever wondered what dark matter is or why galaxies collide? And would you recognise a quasar or a quark if you bumped into one in a dark alley?

Fred Watson has taken the many, many questions that have been asked by his radio audience, and answered them in Why Is Uranus Upside Down? This highly entertaining and informative introduction to our planet and the universe we live in is a must-read for inquiring minds of all ages.
