The Great Courses (Firm)
Description
Greek has several ways of talking about the past. Focus on the imperfect tense, which describes an action that was ongoing in the past—for example, "The Achaeans were dishonoring the gods."The imperfect is built by adding a vowel prefix, called an augment, to the verb base, plus secondary endings.

From 1914 to 1921, while Ireland faced revolution at home, James Joyce was abroad, slowly laboring on his great masterpiece, Ulysses. In this first of three lectures about this famous epic and its relation to Irish history, Professor Conner provides a lucid overview of the story, its characters, its style, and its structure.
Description
Is deliberate killing justified when it happens during wartime? Consider this powerful question by looking at how depersonalization helps soldiers become more comfortable with killing; how civilizations and religious traditions have morally justified war; and arguments for (and criticism of) a pacifist approach to life.
Description
There are many internal and external barriers out there that can inhibit us from effective creative thinking. But you don't have to let these physical and perceptual blocks and habits deter you. Instead, learn how to beat them back with research-backed strategies that involve deferring judgment, defocusing, and distancing.
Description
Consider an approach to creating robots that’s inspired not by maps but by the simple sense-and-act behavior of animals. You’ll learn the benefits of behavior-based robotic architecture (including quicker reactions and stronger sensors), and see how simple animals including ants have inspired roboticists to build fascinating inventions..
Description
The beginnings of the end of Eastern European communism came with the firing of a shipyard worker in Gdansk, which led to a workers uprising and the founding of the Solidarity political movement. Dive into these exciting events, from rebellion to state crackdown, and meet some of the key players who altered the course of history..
Description
Finally, learn about the new field of positive psychology, and how mindfulness practices foster empirically-supported paths to happiness. Consider the many things that we mistakenly assume will produce happiness, and the alternative of a reliable avenue to well-being, grounded in attention to the present moment, engagement in life, gratitude, and connectedness to others.
Description
Classify all different types of four-sided polygons (called quadrilaterals) and learn the surprising characteristics about the diagonals and interior angles of rectangles, rhombuses, trapezoids, and more. Also see how real-life objects—like ironing boards—exhibit these geometric characteristics.
Description
Here you’ll revisit the idea that science fiction often deals directly with the consequences of human actions, whether through robots who take over the world or massive storms produced by climate change. Starting with a common theme in many science fiction novels, bugs, Professor Wolfe walks you through works that feature—and often correctly predicted—environmental concerns and ramifications..
Description
Melodies and harmonies combine pitches according to rules that we have internalized through experience. Listen to musical examples that demonstrate unresolved and resolved expectations. Consider the analogy to grammar in language, and search for a connection between music and language in the brain..
Description
Consider some key tools used in yoga to address physical pain: attention to breath and sensation, release of chronic muscle contractions, and healthier movement patterns. Practice asanas for each of these pain reduction techniques - including a chest opener, yoga pushup, plank, and staff pose.
Description
Scientists debate whether aging is actually a disease, but the effects of aging indisputably resemble the symptoms of a disease. Here, examine three major mechanisms behind these effects: energy consumption, free radicals, and damage to our DNA. Then consider whether there could be a way to "cure"these effects.
Description
Underwater photography is tricky, expensive, and often requires bulky special equipment. But there are certain strategies anyone can use to capture great photographs in aquatic environments. In this lesson, experiment with underwater shots (and have some fun!) using everyday tools like smartphones and a 10-gallon aquarium..
Description
Visit the land of topology, where one shape morphs into another by stretching, pushing, pulling, and deforming - no cutting allowed. Start simply, with figures such as the Möbius strip and torus. Then get truly strange with the Alexander horned sphere and Klein bottle. Study the minimum number of colors needed to distinguish their different regions.
Description
More than 40,000 Russians were slain at the hands of the Mongols at the Kalka River, including six princes and 70 noblemen. Examine the factors that led to the allied army’s defeat, from underestimating the Mongols to repeatedly allowing their leader, Subotai, to maneuver his opponents onto ground of his own choosing..

The Napoleonic Wars—and Beethoven’s conflicted feelings toward Napoleon—were elemental in another important episode in the composer’s life. Trace Beethoven’s increasing animosity toward the French, and observe the unfolding debacle of Napoleon’s Peninsular War against Portugal and Spain. Learn how Beethoven came to compose Wellington’s Victory, celebrating the British commander’s triumph over the French at Vitoria, which was both a...
