When we talk about digital cameras, we can’t avoid talking about pixels. Ever wonder about where the word ‘’pixel’’ comes from? At the communications exhibit at Liberty Science Center, I was so intrigued to learn that the word is actually a shortening of the original term ‘’picture element.’’ Word origins are fascinating. Most of the original computer terminology was based on the physical nature of the item. A floppy disk was literally a 5” square flexible disk. The hard drive was metal and impermeable, and a mouse looked somewhat like a small rodent with the wire as its tail.
