What will we do in astro 4

What will We Do in Astro 4?

  • We start with the nature of Science, reason, and the principles of clear thinking. My own “Chapter 0” on the principles of clear thinking and scientific method

  • Some basic ideas: Forces, Gravity, the nature of light and matter

  • The sun, our up-close look at a typical star

  • Then to boldly go, on to the stars! How they’re born, their lives, their deaths, and how death gives rise to new life

  • Violence in Space! Supernovae, black holes, gamma ray bursts

  • Then galaxies and the supermassive black holes at their heart

  • The Big Bang origin of the Universe. Inflation, Dark Matter, Dark Energy

  • The idea of the MultiVerse, the Anthropic principle and the intimate connection between alternate universes and the nature of life

  • I’ll stress the observational facts and how we use scientific inference to arrive at ideas, and to test them to arrive at our current theories of the Universe. Exams will stress getting a picture of processes and the ‘why’ behind what we see, not so much on memorized factoids.
