The Hand-held Calculator Turns 40
Why, just tonight, at "back to school night" at my son's middle school. that wacky science teacher Mr. Jones held up this complicated-looking programmable graphing calculator and made some comment about how we -- us middle-aged parents -- didn't even have calculators when we were in middle school.
Yeah, well...
In fact, the hand-held calculator turns 40 this week. Four decades ago, Texas Instruments introduced the first one, the Cal-Tech. Priced at hundreds of dollars, I remember that they were a curiosity, not a tool. It was astounding that little lights could form numbers on a screen.
And now calculators are so cheap, they're handed out as giveaways.
