Does the celebrated harmonic series diverge or converge? Discover a proof using the integral test. Then generalize to define an entire class of series called p-series, and prove a theorem showing when they converge. Close with the sum of the harmonic series, the fascinating Euler-Mascheroni constant, which is not known to be rational or irrational.

The course examines one of the greatest conflicts in human history, World War II. Between 1937 and 1945, 55 million people perished. It was a series of interrelated conflicts; no continent was left untouched, no ocean or sea unaffected. World War II taught lessons that none can ever study enough. Professor Thomas Childers uses the dual perspective of military and social history to explain both the epic course and epoch-making effects of the ‘last...

Explore how it's possible for us to find meaning in life - even when confronted with the finality of it. Drawing on the work of cultural anthropologist Ernest Becker, discover how forms of death denial serve to allay fears about our insignificance, and how we can cultivate meaning in the face of mortality.

Since the dawn of humanity, corpses have held lasting significance for us. In this lecture, probe the various ways human civilizations have "disposed" of corpses - from burial (the oldest method for which evidence still exists) and mummification to cremation and natural exposure (known as "excarnation").

None of us can avoid dying. But some believe we can learn how to die well. Professor Berkson introduces you to ways that others have faced death (with regret, dignity, even rage) and also considers some of the practical ways we can make the best of our deaths when our time comes.

In the first of several lectures on how major world faiths approach death, the focus is on Judaism. From the importance of mourning and burial rites to the recent resurgence in American Jewish belief in an afterlife, go inside the evolving views on death and the afterlife in Jewish history.

Learn the 24 letters of the Greek alphabet using the restored classical pronunciation, recognizing that there was some variation in pronunciation in the ancient world. Practice the pairings of vowels called diphthongs, and sound out a selection of words that you will soon be reading in sentences.

In this lecture on what Professor Berkson calls "an inescapable part of the human condition," unpack the feelings and behaviors of the grieving process. Topics include the evolutionary benefits of grief, the five stages of grief laid out by Elizabeth Kübler-Ross, and the three categories of grieving identified by psychologist George Bonanno.
