Regarded as one of the foremost playwrights of the nineteenth century, Ibsen tells the story of the idealist Doctor Thomas Stockmann, the medical officer of a recently opened spa in a small town in southern Norway, who finds that the water is seriously contaminated. He notifies members of the community and initially receives support and thanks for the discovery. Threatened by the possible impact of such a revelation, his brother, the town mayor, conspires...

In a large country house in Derbyshire in April 1809 sits Lady Thomasina Coverly, aged thirteen, and her tutor, Septimus Hodge. Through the window may be seen some of the "five hundred acres inclusive of lake" where Capability Brown's idealized landscape is about to give way to the Gothic style: "everything but vampires," as the garden historian Hannah Jarvis remarks to Bernard Nightingale when they stand in the same room 180 years later. Bernard...

Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for an entire day.

Why can't we answer questions about what happened before the Big Bang, or what goes on at the center of a black hole? Physics may well be the most important subject in the universe, a theoretical realm that ranges from the infinitesimally small to the infinitely vast, its laws governing time, space, and the forces that created our world.

Quantization places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation disturbs that which is being observed. The result is Werner Heisenberg's famous Uncertainty Principle. What exactly does this principle say, and what are the philosophical implications?

The study of motion is not all there is to physics. By the 18th century, scientists were delving into the relationship between the two phenomena. Today, electromagnetism is known to be responsible for the chemical interactions of atoms and molecules and all of modern electronic technology.

With this lecture, you turn from relativity to explore the universe at the smallest scales. By the early 1900s, Ernest Rutherford and colleagues showed that atoms consist of a positively charged nucleus surrounded by negatively charged electrons whirling around it. But Rutherford's model could not explain all the observed phenomena.
