Chapters 1-16
Chapter 1
• “What is science?”
• The scale of the universe (order)
• Constellations (not really close together)
• Day/Month/Year (e.g., sidereal vs. synodic mo.) • What causes seasons (axis tiltàsun
higher)
• Cycle of moon (~ 1 month)
• Lunar eclipses (why not every month?)
• Solar eclipses (total vs. annular)
• Parallax and angular size (conceptual)
Chapter 2
• Geocentric model -- Epicycles, perfect circles & spheres
• Heliocentric model – How did Galileo PROVE IT! (Jupiter’s moons, Venus’ phases,
etc.)
• Why the Galileo controversy? (from academics, from church, etc.)
• Kepler’s LawsàEllipses, sweep out equal areas,
• Newton’s Laws, Gravity, and orbital speeds (conceptual / application / recognize
equations)
Chapter 3
• Light = wave (diffraction patterns, bends around corners, bends through lenses)
• Light = particle (Energy of a photon goes up with frequency; recognize Eq.)
• Romeràmeasured c with Jupiter’s moons
• Time dilation (concept), length contraction, etc. • Whole EM spectrum (all just “light”)
• Wein’s Law (hotteràbluer); recognize Eq.
• Doppler Effect (l.o.s. velocityàcolor shift)
Chapter 4
•Spectral lines (unique to each element)
• Emission vs. absorption lines vs. continuum (what causes each)
•Spectral analysis (how spectra tell us stuff)
• Temperature
• Composition
• Rotation
• Line of sight velocity (Doppler shift of spectral lines)

Chapter 5
• Reflection vs. refraction telescopes
• Bri
• Resolution better w/ big R or small wavelength • Space vs. ground
• Atmosphere blurring, Adaptive Optics
• Some have to be in space (UV, X-ray) • Telescope “types” (radio, optical, x-ray) •
Interferometry
Chapter 5 (contd.)
What we “see” in different wavelengths:
• Radio à “cold” neutral hydrogen gas
• Infrared à “cool” dust, “cool” stars
• Visible à “normal” stars (most of them)
• UV à hot gas, very hot “young” stars
• X-ray à super hot plasma!
• Gamma Ray à super crazy high energy stuff! (black holes, supernova)
Chapter 6 (the Solar System)
• Terrestrial (small, rocky, few moons, closer in) vs.
Jovian (big, gaseous, lots of moons)
• Asteroid/meteor vs. comets
• Why isn’t Pluto a planet?
• General properties of solar system (disk, same rotation, planets isolated, planet
dichotomy)
• Nebular Theory of solar system formation • How it explains what we see
Chapter 16 (the Sun)
• Radiation vs. Convection energy transport
• Different Layers (photosphere, corona, etc.)
• Equilibrium (pressure out, gravity in)
• Fusion in Core. Density/Temp changes with radius • Corona (much ho • Lifetime,
• Magnetic Fields
• Wrap around planet
• Sunspots! (11 year cycle)
• Prominences, solar flares, CME’s, solar wind
Chapter 7 (Earth)
• Structure (Inner core .... Magnetosphere)
