Our agenda for today (I will be out for part of the day):

1. Do as much on the lab as you can without me. If you get the data typed into Excel, you're on schedule.
2. Add a column at the end, labeled "R", which computes the distance between Saturn and Titan as follows:
=SQRT((G2-I2)^2+(H2-J2)^2)

This assumes column G and H are x values, and I and J are Y values.

3. Add a new column at the end, labeled "TIME," which computes the decimal time as follows:
=MONTH(A2)+DAY(B2)+YEAR(C2)+HOUR(D2)+MINUTE(E2)+SECOND(F2)

Make sure that column A is the month, B the day, and C the year. Edit appropriately.

4. Fill these last columns down so that all 19 calculations are done.

5. Put your name in the spreadsheet, save on the server, and go on to the next thing. Don't print it; it isn't finished yet.

6. Do the "telescopes" puzzle I leave with the sub. The puzzle is due at the end of the class, so leave it with the sub.

7. On Monday we'll continue with the lab. If you finish everything else, begin preparing notes for the test. The test will not be until the end of next week, but you will be allowed to use one page of notes (1 page, 8x10 inches, double sided).

The sub gets to decide if you have to turn in #7.
