  1. Objectives (AKA Purpose)

    2. The main objective is to learn a bit about     cosmology---modern, physical cosmology.

    We touch on the following topics:

    1. the expanding universe.
    2. Hubble's law.
    3. the accelerating universe.
    4. dark energy.
    5. the Big Bang.
    6. the large-scale structure of the universe.
    7. dark matter.
    8. the multiverse.

    Warning: file_to_include.html could not be included.

  2. Preparation

    3. Do the preparation required by your lab instructor.

    1. Prep Items:

      1. Read this lab exercise itself: Lab 12: Cosmos.

        Some of the Tasks can be completed ahead of the lab period. Doing some of them ahead of lab period would be helpful.

      2. Print out a copy of the Report Form before coming to the lab if at all possible.

        The Lab Exercise itself is NOT printed in the lab ever. That would be killing forests and the Lab Exercise is designed to be a web active document.

        You can print a copy on your own printer if you like.

      3. Prep for the quiz doing the prep suggested by your instructor.

        General remarks about quiz prep are given at Quiz Preparation.

        For DavidJ's lab sections, the quiz prep is doing all the items listed here and self-testing with the Prep Quiz if it exists.

      4. There are are many keywords that you need to know for this lab. Many of these you will learn sufficiently well by reading over the Lab Exercise itself.

        However to complement and/or supplement the reading, you should read a SUFFICIENT amount of the articles linked to the following keywords etc. so that you can define and/or understand the keywords etc. at the level of our class:

        A longer and list of keywords which you are NOT required to looke at---but it would be useful to do so---is:
