\chapter{What is Physics?}
\label{pintro}


Physics is the study of the world around us. In a sense we are more
qualified to do physics than any other science. From the day we are
born we study the things around us in an effort to understand how
they work and relate to each other. Learning how to catch or throw 
a ball is a physics undertaking for example.

In the field of study we refer to as physics we just try to make
the things everyone has been studying more clear. We attempt to
describe them through simple rules and mathematics. Mathematics is
merely the language we use.

The best approach to physics is to relate everything you learn to 
things you have already noticed in your everyday life. Sometimes when 
you look at things closely you discover things you had overlooked intially.

It is the continued scrutiny of everything we know about the world around us
that leads people to the lifelong study of physics. You can start with asking a 
simple question like "Why is the sky blue?" which could lead you to electromagnetic
waves which in turn could lead you wave particle duality and to energy levels of atoms
and before long you are studying quantum mechanics or the structure of the universe.

In the sections that follow notice that we will try to describe how we will 
communicate the things we are dealing with. This is our langauge. Once this is done
we can begin the adventure of looking more closely at the world we live in.


/nts{Descriptions relating to these questions must be included:
What is meant by a theory?

How does a hypothesis become part of a law?

(a) Define the term "laboratory." (b) How does your school's physics laboratory fit this definition?

Distinguish between science and technology.}
