From the Publisher
National Geographic answers all the questions about how things
work--the science, technology, biology, chemistry, physics, and
mechanics--in an indispensible book that reveals the science behind
virtually everything. How does the voice of a distant radio
announcer make it through your alarm clock in the morning? How does
your gas stove work? How does the remote control open your garage
door? What happens when you turn the key in the ignition? What do
antibiotics really do? Divided into four big realms--Mechanics,
Natural Forces, Materials & Chemistry, Biology &
Medicine--The Science of Everything takes readers on
a fascinating tour, using plain talk, colorful photography,
instructive diagrams, and everyday examples to explain the science
behind all the things we take for granted in our modern world.
