Author breaks down quantities, probabilities, time, frequency, money, days until you earn $1000, dollars per kilogram, kilograms per dollar, energy, power, kilowatt hours, milli-amp hours, energy storage density, dollars per kilowatt hour, kilowatt hours per dollar, and information into digestible comparisons. From the minuscule (single DNA bond energy) to the planetary (world economy), each metric is placed on a scale with real-world examples that are easily relatable. Surprising comparisons like fast computer operations (Time -9) and the energy needed for a lightning storm (Power 11) are thought-provoking. The extensive details on various metrics help put the vast range of these quantities into perspective.
