The principles of electrochemical cell design are explained through batteries, sensors, and ansolar-powered car.
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.
Topology, known as "rubber sheet math," is a field of mathematics that concerns those properties of an object that remain the same even when the object is stretched and squashed. In this unit we investigate topology's seminal relationship to network theory, the study of connectedness, and its critical function in understanding the shape of the universe in which we live.

This program on fractions is the fifth of 13 programs within the mathematics section of the series GED Connection. This episode explains the concept and many applications of fractions to make them more understandable and useful to adult learners who may have been previously intimidated by them. It explains a fraction as both a part-to-whole relationship as well as another way to write a division problem, using numerator and denominator. The program shows real-life uses of fractions in accurately measuring something, keeping time to musical beats, and in a horse trainer's calculations of required dosage and supply of medicine needed. The program explains how to find common denominators for adding and subtracting fractions, as well as how to subtract by borrowing from the whole number. Cross canceling or factoring is shown to be an easy way of simplifying a problem. Composites, numbers with many factors, and prime numbers, those whose only factors are one and themselves, are also addressed. Dividing is shown to be the same as multiplying by the reciprocal; and dividing by a number less than one is done the same way, except the result is a higher number than the dividend.
