Internet Exercise # 1
The Movers and the Shakers in Geology
The main focus of our efforts in ‘Historical Geology’ centers on understanding and getting comfortable with TIME. In our society today, TIME has become compressed: we communicate instantly around the globe; we communicate with spacecraft billions of miles away in minutes; and travel across the continents in four hours. Our politicians think of TIME in terms of four-year or two-year terms, and we budget our spending on fiscal cycles ranging from paychecks every two weeks to paying taxes every year. Unfortunately, our growing sense of “instant gratification” causes us to lose touch with the real TIME. By that I mean DEEP TIME…Millions and Billions of years. DEEP TIME is the common thread that runs through this entire class.
We begin our discussion with a look at some of the really important people who helped build the scientific consensus on geologic principles and processes. In fact, this is a history lesson. As you do your research on the internet, keep our main theme in the back of your mind…TIME. Most of the scientific movers and shakers you’re going to meet made their incredible contributions to scientific thought over the last 1500 years or so. Given that we believe that the earth is at least 4.5 billion years old, does that 1500- year span of history seem like a long time to you? Also, keep thinking about how big the world really was to these people in their TIME.
Let’s meet the players.
