Reviews

"How big is big? How small is small? As an astronaut and citizen explorer, I love having someone explain some of the more puzzling aspects of our universe to me in terms that make sense. With Magnitude, my brain cried "Eureka!" every time I turned the page."
--Cady Coleman, PhD, former NASAAstronaut

"Through clear text and illuminating illustrations, the authors tackle questions ranging from 'how does the mass of a human eyelash compare to the mass of the black hole at the center of our galaxy?' to 'how fast does a dentist's drill rotate?' A fascinating journey through the measure of all things."
