|Physics is an organized way of conversing with nature.
Physicists ask questions; nature responds. For many questions, the
answers are almost predictable, but when the question is a
particularly good one, the answer can be unexpected and give us new
knowledge of the way the world works. These are the moments
physicists live for.

KNOW?Did you know that an
amusement park is a life-size physics lab? You can feel the
physical forces in action. Concepts like acceleration,
momentum, gravitational potential energy, and weightlessness
become real as you experience the roller coaster, the
colliding bumper car, the swinging cages, or the fall-away
floor. These are concepts explained in physics courses.
|The fundamental ideas of physics underlie all basic science --
astronomy, biology, chemistry, and geology. Physics also is
essential to the applied science and engineering that has taken
||our world from the horse and buggy to the supersonic jet, from
the candle to the laser, from the pony express to the fax, from live
smoke signals to live satellite transmission, from the beads of an
abacus to the chips of a computer.|
Today physics is as
exciting as ever. The animated conversation between physicists and
nature goes on and it shows no sign of
optics used in telecommunications.
