Since others judge you by the way you speak, the intricacies of grammar, in fact, should not be relegated to the realm of fussy "guardians of the language," but are rather essential clues all can employ to communicate more exactly. In such a light, this course forms an invaluable guide for everyone from all fields of interest.

The works of J.R.R. Tolkien are quite possibly the most widely read pieces of literature written in the 20th century. But as Professor Michael Drout illuminates in this engaging course of lectures, Tolkien's writings are built upon a centuries-old literary tradition that developed in Europe and is quite uniquely Western in its outlook and style. Drout explores how that tradition still resonates with us to this day, even if many Modernist critics would argue otherwise. He begins the course with the allegory of a tower....

In this course, Professor Michael D. C. Drout traces literature back to its ultimate sources in oral tradition. Drout shows us how works as varied as the Odyssey, Beowulf, the Finnish Kalevala, and epic songs from the former Yugoslavia were shaped by their origins as songs sung - and composed - before a live audience. Understanding the oral roots of these great works lets us see them in a whole new light.

Geology is often thought of as simply the study of rocks. In reality, geology is the study of our planet on all scales, from microscopic to planet-wide, and ranging in time from almost instantaneous events, like earthquakes, to the glacially slow motion of the tectonic plates. Everything we know about our world from a geologic perspective is based on information locked into the rock record and the job of a geologist is to tease out that story through a wide variety of observations. This insightful course explores a range of topics that help to tell the story of Earth and to explain the discipline of Geology and the role of the geologist.

An esteemed professor of biology at Wheaton College, John Kricher leads a fascinating discussion of the approximately 10,000 species of birds that share our world. In these engaging lectures, Kricher expands on such topics as bird anatomy, the mechanics of flight, migration, reproduction, and song. The professor's lively presentation demonstrates how understanding the traits, life cycle, and evolution of birds is critical for an understanding of the origins and evolution of life on earth - and why conservation plays a vital role in the environment's delicate balance.
