Your assignment for today's presentaion by Dr. Polhemus is to respond to the following 3 questions. Don't just state your opinion; try to justify your answers. Why do you think the way you do? Are you using logic to support your ideas? Emotion? Sense perception? Authority? Consensus? Faith? Something else?
A second part of this assignment is to respond/comment on the responses of at least two other responses.
- After listening to and viewing Dr. Polhemus, do you think dark matter exists? Did he convince you? Why or why not?
- What problems exist that may make it difficult for scientists to come to knowledge in an area like dark matter?
- Dr. P. gave several examples of times when astrophysicists have been wrong in the past, but because of new findings, they have shifted to a new way of thinking. (This is called a paradigm shift.) Explain a paradigm shift you have experienced. What was the original idea or theory, and what caused you to shift?
This is due by next Friday, Oct. 31.
