If you've ever wondered what makes lightning, why a boomerang
returns, how ice skaters can spin so fast, how Michael Jordan can
"fly," why waves crash on the beach, how that tiny computer can do
complicated problems, or how long it takes light from a star to reach
us, you have been thinking about some of the same things physicists
study every day. Physicists like to ask questions. They try to find answers for almost
everything_from when the universe began to why soda fizzes. If you
like to explore and figure out why things are the way they are, you
might like physics.If you've had a back-row seat at a rock concert, and could still hear,
you experienced physics at work! Physicists studying sound contribute
to the design of concert halls and the amplification equipment.
Knowing more about how things move and interact can be used to manage
the flow of traffic and help cities avoid grid lock.
