* Modern Cosmological Observations
and Problems*
Welcome to the Instructors Area. If you
are using this book for an undergraduate or graduate course please
email me for the
real URL to more problems and data. Below is just an example.

Also, if you are interested in seeing a whole course that is
sort of designed around the book, see
Physics 410/510

Suggested Exercises for Chapter 1:

####
1. Find some Cosmological N-body simulations on the World Wide Web
and look at them. Here is a good place to start .
Describe their components and the overall behavior of the simulation
in terms of predictions that you would make about the observable
Universe. What are some of the limitations of these simulations?
2. Integrate equation 20 to produce equation 23.

3. Using the expression for critical density determine the critical
density in grams per cubic centimeter when H is in units of
100 km/s Mpc^{-1}

4. We will later make use of a quantity known as the * dynamical
timescale *. Give a physical argument that shows why this
timescale goes as:

(G*rho)^{-1/2}

where rho = density.

5. Verify that rho goes as R(t)^{-3} is the solution to
equation 30.
