"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics.

Charles Darwin's theory of organic evolution-the idea that life on earth is the product of purely natural causes, not the hand of God-set off shock waves that continue to reverberate through Western society, and especially the United States. What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? These 12 eye-opening lectures are an examination of the varied elements that so often make this science the object of strong sentiments and heated debate.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts.

Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Conventional wisdom suggests there is a sharp distinction between emotion and reason. Emotions are seen as inferior, disruptive, primitive, and even bestial forces.
