Recently, my youngest son, Joshua, asked us when the wheel was invented. My wife and I attempted to answer, trying to remember and figure it out.
Well, oddly enough, the answer is in this month’s Scientific American Magazine, in a book review of The Looting of the Iraq Museum, Baghdad : The Lost Legacy of Ancient Mesopotamia. It turns out that we both guessed wrongly by thousands of years. A little more research on the web showed that the wheel was invented about 5500 years ago, shortly after writing.
Oddly enough, the wheel came shortly after plywood and roads, and somewhat after beer. So, we can draw the obvious conclusion that all of these inventions were made for beer delivery. Writing was clearly designed to help keep track of your beer tab.
