Astronomy 162: Professor Barbara Ryden

Monday, January 6

INTRODUCTION


Course Logistics

Much of the first lecture was devoted to covering the material in the course syllabus.

MAIN CONCEPTS COVERED BY THE COURSE

(1) Structure and evolution of STARS

(Weeks 1-6)

(2) Structure and evolution of GALAXIES

(Weeks 7-8)

(3) Structure and evolution of the UNIVERSE

(Weeks 9-10)

MAIN QUESTIONS ASKED DURING THE COURSE

(1) What do astronomers know?

(2) How have they learned it?

In other words, we'll learn not only some of the facts which scientists have deduced, but also learn a little bit about how science works.

The Astronomer's Motto:

LOOK BUT DON'T TOUCH.

Most of what astronomers know comes from gathering very faint light from very distant sources.
