Earth Science: Geology, the Environment, and the Universe
The Nature of Science
Problem of the Week
That was then. This is now.
"Necessity is the mother of invention." This is an American
saying that most teenagers probably have not heard. It suggests that inventions
are sometimes created to fill specific needs. People generally create
and invent because they see a need or have a desire to do something that
can't be done because current technology. Sometimes, inventions are the
by-product of scientific investigations or advances in technology. As
scientists seek answers to the questions that interest them, someone else
sees the potential in it, and uses their discovery in ways the originators
never dreamed about. For example, did you know that CAT Scanners and MRI
technology (Computer-Aided Tomography and Magnetic Resonance Imaging),
used in hospitals worldwide, came from technology developed to computer-enhance
pictures of the moon for the Apollo program (http://www.sti.nasa.gov/tto/apollo.htm)
How have travel, communication, computer technology, and other types
of technology changed since you were in first grade? What is different?
What is better? Have things changed that much? What changes have taken
place over a longer period of time? How have advances in all kinds of
technology made our lives different?
The time is 1950
The time is the present.
You need to set up a meeting between 3 geologists; one from Tokyo, Japan, the second from Cairo,
Egypt, and the third from San Diego, California.
Plan this meeting using the latest technology, machines, tools, and devices that are available
to you at the time.
You choose where they meet.
Time and Cost
Within these limitations you need to make the meeting take
place in the most time efficient and cost effective manner.
