How Fast Are You Moving When You Are Sitting Still?
by Andrew Fraknoi, Foothill College & the Astronomical Society of the Pacific
Have you ever considered how fast you are really moving when it seems you are not moving at all? How fast does the Earth move in its daily rotation and in its yearly revolution around the Sun? How fast do we travel together with the Sun through the Milky Way Galaxy and how quickly does the galaxy move through the universe? Find out more in this issue.
Topics include:
* Daily and yearly motion
* The Sun's motion within the Milky Way Galaxy
* The galaxy's motion through the universe
* The Big Bang
* Cosmic Background Radiation
* Two classroom activities about our place in space and time
