Questions for Discussion: Galileo's Inclined Plane
How did Galileo slow down motion so he could measure the motion of a falling object? Make a chart that shows the pattern Galileo discovered when he measured the units of distance a falling object covers in each unit of time. Use a sketch to explain what "this beautiful numerical progression--one, three, five, seven" means. What is special about the sums of odd integers? Why do the 50 stars on the American flag fit so well? Try adding up the rows of stars, starting in a corner. Notice the sequence 1+3+5+ and so on. Why does it stop at 9?
