## About Physics

Physics is science. One of the most fundamental scientific disciplines, physics investigates how matter and energy change with space and time.

Physics advances technology. Physics is behind all the different technologies in a cell phone. Physics explains how electromagnetic waves encode information between a cell phone and tower, how electricity in the computer chips is controlled by transistors, resistors, and other elements, how a phone's speaker produces changing waves of air pressure, and how a phone uses GPS to know its position.

Physics guides engineering. Physics gives helps engineers design, build, tinker, and experiment by allowing them to predict how things behave.

Physics speaks with math. Math is the language physics uses to predict and communicate the nature of our universe.

## Materials

An organized notebook/binder and a scientific calculator is required.
I'm flexible about most other details, but I recommend:

graph paper: for graphing, charts, free body diagrams, circuit diagrams, ...
scientific calculator: TI-30XIIS is cheap and works well.
pen or pencil: I like these colored pens.
highlighter
