Mathematics is the language of science, and numbers are at the heart of all physical sciences-understand the numbers, and you'll have a better understanding of the science. Physics in 100 numbers explores the most important and interesting numbers in physics, starting with the lowest number (10-43 seconds, or "Planck time," the smallest time measurement possible) and working in numerical order up to the very largest (4 x 1069, which is the estimated mass-energy of the universe, in Joules). Whether you read it from cover to cover, dip in and out at random, or decide to read one number a day, you'll discover a wide range of facts, figures, and formulas, presented in a way that is uniquely easy to grasp. From the mass of an electron to the age of the universe, Physics in 100 Numbers is an insightful and accessible guide that will enlighten, inform, and entertain readers of all levels.
