"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.

Prince Lyov Nikolayevitch Myshkin is one of the great characters in Russian literature. Is he a saint or just naïve? Is he an idealist or, as many in General Epanchin's society feel, an "idiot"? Certainly his return to St. Petersburg after years in a Swiss clinic has a dramatic effect on the beautiful Aglaia, youngest of the Epanchin daughters, and on the charismatic but willful Nastasya Filippovna. As he paints a vivid picture of Russian society, Dostoyevsky shows how principles conflict with emotions - with tragic results.

In this 24-lesson course aimed at non-scientists, noted particle physicist Dr. Don Lincoln of Fermi National Accelerator Laboratory covers more than a century of progress in physics, describing exactly how scientists reach the conclusions they do. He starts with the atom, which was long hypothesized but wasn’t definitively proven until a paper by Albert Einstein in 1905. That was just the beginning, as researchers probed ever deeper into the atom’s complex structure, leading to the weird findings of quantum mechanics.
