Gravity

This is a brilliant and accessible illustrated book about gravity and gravitational waves, whose existence was only confirmed experimentally in 2016 and resulted in the award of the Nobel Prize in physics in 2017. It draws on first-hand experience with many practical insights and useful extra focuses, and encouraged me to do an experiment comparing dropping sheet of paper and a book separately, then putting the sheet of paper on top of the book - they fall together as the book protects the paper from friction forces in the air. The author describes the history of work on gravity, ranging over physics and cosmology with more recent detail on the quest for gravitational waves. I gained a better understanding of the Big Bang in relation to the universe being infinite with a clever analogy of different scales of markings on a rope. At the end, the author speculates on the future dominance of dark energy for a new phase of inflation. The book will surely become a classic in explaining gravity in such an engaging manner, reflecting as it does the late author's stellar reputation as a science communicator.
