Meet astronomer Doug Duncan
1. Description and video of a total eclipse - watch people and animals freak out!
2. How to watch an eclipse
3. Overview of Course Topics and Goals
4. Eclipses of the sun.
5. Total vs. partial eclipses
6. How Astronomers Study the Sun. The Sun's size compared with earth.
7. Sunspots and the solar activity cycle
You can start final project now!
1. Why we mostly study the sun with different kinds of light, rather than spacecraft.
2. What is light? Differences between red, blue, ultraviolet, and X-ray light.
3. Properties of light. White light. Kirchhoff-Bunsen laws. How color tells you temperature.
4. Don’t be fooled by reflected light!
5. Is light a Wave? Is it a particle? It’s both! The strange world of quantum physics.
6. Spectrum lines – how they tell us what the sun is made of; the quantum origin of spectrum lines.
7. How visible light, ultraviolet, X-rays reveal the sun’s photosphere, chromosphere, and corona. Magnetic fields and the solar wind.
1. Review of Week 2; overview of Week 3.
2. Newton's law of gravity
3. The "pefect gas" law that explains temperature, pressure, and density
4. Inside the sun; nuclear energy generation.
5. The transport of energy from the sun's core to the surface
6. Neutrinos and Sunquakes (solar seismology)
7. Einstein proved right by a total eclipse - gravity warps space!
1. What week 4 will cover
2. Regions of star formation in space.
3. Converting gravitational potential energy into kinetic energy heats forming stars.
4. Conservation of angular momentum causes a new star to spin.
5. A previous generation of stars made the elements that formed the sun and planets.
6. Different kinds of stars make different elements and recyle them into the galaxy.
7. The formation of the planets around the sun.
1. Quick recap of weeks 1-4 and an outline of what week 5 will cover.
2. Eclipses of the sun and moon. Who sees a total eclipse and who sees a partial eclipse?
3. A personal description of the incredible drama of a total eclipse, how animals respond, how to watch safely.
4. How to conduct neighborhood eclipse watching. How to make money and friends by being the one who prepares before eclipse day. Answers to Frequently Asked Questions. How to SAFELY use binoculars with a group.
