ResearchMethods: (I) The Night Sky, Critical Thinking & Science (U1-P1) [VID] Sp13

When I was little I wanted to be an astronomer.  My family lived out in the country, so the sky was clear and beautiful, filled with stars.  I was fascinated, full of questions.

As a grew up and got into college and grad school, my research interests changed, but I still have a fondness for the night sky and astronomers.

Carl Sagan is an astronomer-hero of mine. More recently Neil deGrasse Tyson fills Sagan's shoes. What these astronomers have to say goes beyond the stars. As scientists, what they teach is a way of thinking, how to think critically.

The Thinker's Way by John Chaffee is a good place to start a journey into critical thinking.  Some of what follows is inspired by this book.

Try this little exercise:
  1. Think of a topic that you know something about.
  2. Write down five things that you know about that topic.
  3. Don't write down definitions.  Write down claims.  Two options: (1) Write that one thing has an effect on another or (2) one group is different from another?  For example, video games cause violence in players or Americans are more individualistic than Chinese.

Now, questions to ponder:

What does it mean to say “I know something”?
What can we know?  How well?
How do we know it?

How would you go about testing these claims?

What claims are the Mythbusters testing?   How?
What issues pop up?
