I was out shopping Saturday night and I heard a cashier marvel about receiving a $100 bill.  Is that the largest bill in circulation?

A Milestone for the Steam Engine

Mention the steam engine, and most people think of James Watt.  Actually, the steam engine goes back to the 1st century AD —  the earliest known design, the aeolipile, was described by the Greek mathematician and engineer Hero of Alexandria, as recorded in his manuscript Spiritalia seu Pneumatica.  On July 2, 1698, British engineer Thomas Savery was

Happy Birthday to the Typewriter
