Course Description:

In the mid-nineteenth century, an obscure pharmacist named Heinrich Schwabe of Dessau, Germany discovered that the number of sunspots on the Sun came and went with an 11-year cycle. Since, as the song goes, "The Sun is a mass of incandescent gas, a gigantic nuclear furnace," what could possibly be keeping time inside? This lecture will cover some of the history of our preoccupation with sunspots (ranging back to ancient China), and our current, incomplete understanding of how they are produced on the Sun. The Sun's magnetic field, the Solar Wind, the weather on Earth, even the stock market and climate change will make appearances.
