Special
Problem 1: For the period from 1900 to 1980, calculate the
log base e (ln) of the world
population values and plot them on the vertical axis against the year on the horiontal
axis. Draw the best straight line
you can through these point and
determine its slope, k. What is the exponential equation for this line?
Is an exponential a good fit over this 80 year period? Can you think
of a function that might do a bit better?

News
and Articles of Interest
1.) Physics Colloquia
[http://events.iu.edu/webevent.cgi?cmd=listmonth;calID=320348;y=2009;d=1;m=9]
are held each Wednesday at 4:00 p.m. in Swain West 119, just down
stairs.
I'll announce those that have some relationship to the material in this
course. The first colloquium this fall will be on September 9:
Mark Hess of Indiana University will talk about High Spacecharge Beams.
2.) Geography Colloquia
and seminars may often be of interest to you. They are usually
held
on Fridays at 4:00 p.m. in the Student Building 150. I'll
announce
those that have some relationship to the course.
3.) SPEA, Geological Sciences,
Biology, and Chemistry[http://geology.indiana.edu/colloquia/index.html]
often have talks relating to Environmental Science. I'll announce
them here when I think they will be of interest.
4.) Interesting web sites and
articles are also useful to the course. Let me know what you
are finding that you think might be interesting to others in the
course..
