I'm so old I Remember when:

[R2elk]

My dad was a math professor and he had a slide rule, anyone remember those?

I still have mine.

So yeah, I also remember REAL typewriters and taking typewriting in college.

We had touch typing class in high school. The final exam was copying a text with a towel draped over your hands and the typewriter keys so you couldn't see the keys.

I remember watching tv the morning the challenger exploded.

I watched it live in my college dorm lounge with about twenty other students. I'll never forget that stunned silence. We couldn't believe what we had just seen happen. Then several of the girls started crying. It was so horrible.

My mom worked as a switchboard operator when they still had to manually connect calls.

Someone skilled with a slide rule could work almost as fast as a calculator.

I've heard centigrade used somewhere (I can't remember where) but I figured it out real fast.

Try Kelvin instead.

0⁰K = -273.15⁰C = -460°F.

Had to use one in the early 60's in chem class. And then again in physics.

Here the penny has been removed from circulation. Costs are rounded up or down if it’s $5.03 then it’s $5.05. If it’s $5.02 then it’s $5.00.

Kids these days do not understand rounding up/down. They need a computerized till to do this.

There was talk of that down here years ago but the public fought it. So now the price of copper is so high that pennies just aren't what they used to be. I'm not sure how much copper is in a penny. I have so old wheat pennies I'm hoarding.
