All sound is the product of airwaves crashing against our eardrums. The mathematical technique for understanding this and other wave phenomena is called the Fourier analysis, which allows the disentangling of a complex wave into basic waves called sinusoids, or sine waves. In this unit we discover how the Fourier analysis is used in creating electronic music and underpins all digital technology.

This program takes a look at the kinds of nonfiction that will appear on the GED Language Arts Reading Test. Nonfiction is based on facts. Reading nonfiction helps people make informed decisions, learn new skills, and accomplish goals at work, school, and in their personal lives. The program begins by following a woman who owns and operates her own day care. She talks about the types of nonfiction that she reads on a daily basis: instruction manuals, how-to books, rules and regulations, etc. This program explains how to read for information and tells the student to ask the question "how is the information organized?" and explains how to use indexes and tables of contents to find information quickly. It suggests that the student use common sense to decide if they should skim a passage or read it carefully. It urges students to look for the main idea and to ask themselves "what does this mean?" as they read. The program also follows a film critic from a local paper. He explains that sometimes the main idea isn't so obvious and that's when the details have to be examined. The program ends with the statement "when you read look for the main idea and the details that support it whether you're reading for information, inspiration, or to pass the GED test."
