Abstract
Astronomers can learn and pursue their profession or hobby in isolation. They can also share it with others through education and outreach. The terms Education and Outreach are sometimes used interchangeably, or are used to refer to formal and informal education, or to school and public education, respectively. The two are related: science education in the schools is strongly affected by the many channels for public education - notably the mass media; public understanding and appreciation of science begins in school. Hereafter, I will use the term Education and Public Outreach (initialism E/PO ), which is widely used in the US where there is lots of money from government and private sources to support it.
