Great paradigm shifts in physics have often resulted from an intuitive mind subjecting simple measurements to rigorous mathematics. This stimulating and stylish guide to the universe offers a route to understanding ostensibly complex cosmological concepts, including the age and distance of stars, Einstein’s theory of gravity and the stages of the Big Bang, via simple acts of observation, measurement and reasoning which, with the help of data from scientific instruments like the Hubble telescope, anyone can perform.
