In this guide, you will find books, articles, and websites that help teachers of astronomy address some of the weird topics on the fringes of science that students sometimes hear about and want to have clarification for. Included are astrology, UFOs as alien spaceships, crop circles, denial of evolution and the big bang, the “face” on Mars, claims that NASA never landed astronauts on the Moon, and others.

Philosophy (from Greek φιλοσοφία, philosophia, literally "love of wisdom") is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. The term was probably coined by Pythagoras (c. 570 – c. 495 BC). Philosophical methods include questioning, critical discussion, rational argument and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? However, philosophers might also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust (if one can get away with it)? Do humans have free will?

This course provides an introduction to major political, social, cultural and intellectual changes in Europe from the beginnings of the Renaissance in Italy around 1300 to the outbreak of the French Revolution at the end of the 1700s. It focuses on the porous boundaries between categories of theology, magic and science, as well as print. It examines how developments in these areas altered European political institutions, social structures, and cultural practices. It also studies men and women, nobles and commoners, as well as Europeans and some non-Europeans with whom they came into contact.

For decades, the media have given enormous attention to sensational claims that vague lights in the sky are actually extra-terrestrial spacecraft. Recently, there has been a flurry of misleading publicity about UFOs on military photographs. A sober examination of these claims reveals that there is a lot LESS to them than first meets the eye: when there is enough evidence, UFO claims can be explained by terrestrial or celestial phenomena (including lights from human craft and re-entering space junk). This up-to-date guide provides key resources available free on the Web, to help scientists, educators, students, and journalists learn about the skeptical perspective (and the background stories) behind these claims.

This course is an introduction to epistemology: the theory of knowledge. We will focus on skepticism—that is, the thesis that we know nothing at all—and we will survey a range of skeptical arguments and responses to skepticism.
