9. I was recently approached by a wild-eyed gentleman who tried explaining to me that the c in Einstein's equation E = mc² was "center of mass" (measured in units of length) rather than the speed of light. Given that the units of energy E are kg m²/s², comment on whether this interpretation of E = mc² could possibly be correct.

10. Most of the homework sets in this class will have a problem that requires use of a computer to solve. The Python programming language is the recommended tool for these problems. You will need an up-to-date version of Python on your computer, as well as a couple additional libraries that add extra mathematical functionality to Python. Go to the "Python" link on the course webpage, click "Problem 1" and install these tools on your computer. Test your installation by following the "Test your installation" instructions on that page.

Once things are working, make a plot of cos(t) with 20 t points ranging from 0 to 2*pi. Plot those 20 points using red circles. Put your name in the title. Label the x axis "theta" and the y axis "cos(theta)". Don't panic if your printer won't print out the red circles in color; but at least figure out how to make them red on your computer screen.
