"What was the first message sent over the internet? How much water does a single person use every day? How was the electric light invented? For every utility people use each day, there's a hidden history below the surface - a story of intrigue, drama, humor, and inequity. This graphic novel provides a guided tour through the science of the past - and how the decisions people made while inventing and constructing early technology still affect the way people use it today"--Provided by publisher.
