Editorial Reviews


Ancient Computers is an excellent introduction to the calculating methods of diverse cultures across time. A mixture of history and practical techniques for understanding and using these ancient devices brings the tools of these long-forgotten civilizations to a wide audience. Stephenson writes in an easy-to-understand and accessible manner and the use of diagrams is extensive.

Want know how to use an abacus or where it came from? This is the book for you!

The book is appropriate for high school audiences and above.

The author ... makes two points that deserve wider dissemination

... first ... the Salamis Tablet ... [has] an additive side and a subtractive side

... second ... historians need to pay more attention to the available tools, technology, notation, and terminology to see how particular algorithms may have been performed.

About the Author

In Tokyo in 1964 I bought a Soroban with Kojima's book "The Japanese Abacus: Its Use and Theory", an event that sparked my interest in abaci ... and in computers.

After getting my M. Eng. (Elect.) degree at Cornell University, my 30 year career included working on the design and construction of nuclear power plants, missile systems software engineering, and industrial and engineering computer systems sales and systems engineering. Deciding to become a high school math teacher at the end of 2000, I took a History of Math course as part of my M.Ed. degree program at UMassLowell. I was struck by how easy it would be to use ancient Roman, Greek, Egyptian, and Babylonian numerals to record abaci calculation results. Prof. Gonzalez asked, "Yes, but how would you do multiplication and division?"

So as a hobby, I've worked the last 10 years to (re-) discover the schematics and programming rules of the computers the Ancients used to do their accounting and engineering to support and empower the greatest empires in human history.

I hope you find Ancient Computers interesting and useful.
