Calculators - 52 Weeks of Personal Genealogy & History -Week 8
With the rapid technological advances in personal computing and the popularity of the World Wide Web over the last couple of decades, it’s hard to believe a handheld calculator was ever considered revolutionary. This baby was a huge deal in our family. Not only would it perform the basic functions of addition, subtraction, multiplication and division, it had a memory, would calculate square root, sine, cosine, tangent and all kinds of other functions that a high school student would need (and that I can no longer remember)!
Consider this: in just a few short years we went from the stone age tools of the slide rule
And the adding machine that had been around for decades,
to a hand held calculator that would add, subtract, multiply, divide, and store the results
To the TI 30. And so on...
It really is similar to the rapid increases in power we have seen in personal computers in the last several years. Actually it is the early stages.
I am just happy that I never had to learn how to use a slide rule!
