It's Dimensional

About the Book

This book is about how to solve difficult real problems by an easy method that uses the dimensions of the problem to derive an answer. Dimensions are things like inches, feet, seconds, and so on that are used to set up the answer to a problem usually described in words. How many meters in a mile? How many seconds in a year? How fast is a car going if it accelerates for ten miles per hour every second for 20 seconds? How far has it traveled? How high is an airplane if a wrench dropped from it takes 30 seconds to hit the ground? How many moles of water in 12 pounds? How much money can be saved by insulating a house?

These and practically all problems that have a dimension can be solved by the methods shown in this book.

The author strongly believes that this method should be taught in all high schools. He believes that 9th grade would be the best starting time and at the beginning of the year. He has called this method Dimensional Analysis. Students would only require two weeks to become proficient.

Mr. Kelly taught three 8th grade classes how to use Dimensional Analysis in only three days. The response by the science teacher and students was strongly positive.

It became clear however that reinforcement of the technique was needed. This book “IT’S DIMENSIONAL” is a result of that perceived need.
