What Do 350+ Years of Science, Mathematics, and Engineering Have in Common?
~ The Slide Rule! ~

The Slide Rule is a mechanical analog computer that in the right hands can do all of the following with accuracy and precision:

  • Multiplication

  • Division

  • Proportions

  • Squares and Square Roots

  • Cubes and Cube Roots

  • Sines, Cosines, Tangents, and Cotangents

  • Algebraic Operations and Logarithms

  • ... and more (depending on the Rule used)!

This program explores the Slide Rule’s role in history’s greatest engineering and scientific achievements, beginning with its invention in the 1600s and ending with its obsolescence in the 1970s. Best of all, we'll learn how to use the Slide Rule and see for ourselves how personal computing was done before the age of electricity and silicon. During this program students will follow my lead in using the Pickett Mircoline 120 Student Prep Slide Rule to perform a range of mathematical operations. Each student will have her/his own slide rule during the program.

*No Advanced Math Skills Required in this program!*

Only everyday experience doing multiplication and division and managing decimal points is needed.

Why A Program on Slide Rules?

When you work on electronic calculators and screens, numbers appear out of nowhere, transform mysteriously inside microcircuits, and then disappear into electronic oblivion, all at the tap of a key. Slide Rules provide a physical, observable pallet for numbers and a way to visualize and even feel how they relate, operate, and change during mathematical operations. The tactile and visual input of a Slide Rule can transform your understanding of math and boost your confidence and proficiency in tackling equations. You'll also develop an appreciation for the genius behind the Slide Rule and the three and a half centuries of invention, calculation, and construction it made possible before our modern world.
