Project MATHEMATICS!
Encyclopedia
Project Mathematics! is a series of educational video modules and accompanying workbooks for teachers, developed to help teach the principles of mathematics to high school students.

Overview

The video modules cover geometry
Geometry
Geometry arose as the field of knowledge dealing with spatial relationships. Geometry was one of the two fields of pre-modern mathematics, the other being the study of numbers ....

Trigonometry
Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves...

 and include a history of Mathematics and examples of how math is used in real world applications. The modules were produced by Dr. Tom M. Apostol

Computer animation is the process used for generating animated images by using computer graphics. The more general term computer generated imagery encompasses both static scenes and dynamic images, while computer animation only refers to moving images....

, created by Dr. James F. Blinn, to visually depict the principles being discussed. Approximately 140,000 of the tapes and DVDs were sent to educational institutions and have been viewed by about 10,000,000 people worldwide over the last 20 years.

Similarity

Discusses how scaling objects does not change their shape and how angles stay the same. Also shows how ratios change for perimeters, areas and volumes.

 was determined and its history. Multiple animations show various ways to determine pi.

Sines and Cosines, Part I (Waves)

Visually depicts how sine
Sine
In mathematics, the sine function is a function of an angle. In a right triangle, sine gives the ratio of the length of the side opposite to an angle to the length of the hypotenuse.Sine is usually listed first amongst the trigonometric functions....

s and cosines are related to waves and a unit circle
Unit circle
In mathematics, a unit circle is a circle with a radius of one. Frequently, especially in trigonometry, "the" unit circle is the circle of radius one centered at the origin in the Cartesian coordinate system in the Euclidean plane...

. Also reviews their relationship to the ratios of side lengths of right triangle
Right triangle
A right triangle or right-angled triangle is a triangle in which one angle is a right angle . The relation between the sides and angles of a right triangle is the basis for trigonometry.-Terminology:The side opposite the right angle is called the hypotenuse...

s.

Sines and Cosines, Part II (Trigonometry)

Explains the law of sines
Law of sines
In trigonometry, the law of sines is an equation relating the lengths of the sides of an arbitrary triangle to the sines of its angles...

 and cosines
Law of cosines
In trigonometry, the law of cosines relates the lengths of the sides of a plane triangle to the cosine of one of its angles. Using notation as in Fig...

 how they relate to sides and angles of a triangle. The module also gives some real life examples of their use.

Sines and Cosines, Part III (Addition formulas)

Describes the addition formulas of sines and cosines and discusses the history of Ptolemy
Ptolemy
Claudius Ptolemy , was a Roman citizen of Egypt who wrote in Greek. He was a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in Egypt under Roman rule, and is believed to have been born in the town of Ptolemais Hermiou in the...

s can approximate sines and cosines. Includes information about cubic splines in design engineering.

The Tunnel of Samos

How did the ancients dig the tunnel of Samos from two opposite sides of a mountain in 500 BC? And how were they able to meet under the mountain? Maybe they used geometry and trigonometry.

Awards

Project Mathematics! has received numerous awards including the Gold Apple award in 1989 from the National Educational Film and Video Festival.

Availability in different languages and formats

The videos have been translated in to Hebrew, Portuguese, French, and Spanish with the DVD version being both English and Spanish. PAL versions of the videos are available as well and efforts are underway to translate the materials in to Korean.

The modules are available on a set of 9 videotapes or 3 DVDs. The videotapes may be freely copied for educational purposes with a few caveats. The DVD version is not freely reproducible.

The video segments for the first 3 modules can be viewed for free at the Project Mathematics! website as streaming video. Selected video segments of the remaining 6 modules are also available for free viewing.

Funding

The majority of the funding came from two grants from the National Science Foundation

totaling $3.1 million. The animation sequences were done on a network of computers donated by Hewlett-Packard. Free distribution of some of the modules was provided by a grant from Intel.

Interactive Project Mathematics!

A web-based version of the materials is being funded by a third grant from the National Science Foundation and is currently in phase 1.
