In high school I bought a calculator to use in Physics class. Not just any calculator, but a Sharp EL-506A Scientific calculator. I fell in love with it. In fact I so much did not want to be without it that I bought two of them. I'd have a backup in case one of them broke.

I remember seeing the beauty and the purity of math and science. Math contained a few axioms but opened up a world of truth. With logic and deduction I could find the answers. What else, I pondered, is out there in our big beautiful world? All we needed, I presumed, are the right answers.

Sadly, I have misplaced the backup EL-506A. But I dug out the original the other night. After a quick trip to the local Walmart, I replaced the batteries and it worked like a champ.

Notice in the photo that my name is scratched into the back of the calculator. Oh my, it's showing pi to 10 digits!
