Earth and the Ether - A Crisis in Physics
In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of Earth relative to the ether. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis.
The Nature of Light and Matter
Episode 2 of The Nature of Matter
Trace a scientific revolution that started with a curious observation about light and a seemingly nonsensical explanation. Learn how Max Planck's proposal that energy is related to frequency, and Albert Einstein's application of this principle to light, gave birth to modern physics.

Mysteries of Modern Physics: Time Series
Time seems to be woven into the very fabric of the universe. But why? In 24 riveting half-hour episodes, Mysteries of Modern Physics: Time shows how a feature of the world that we all experience connects us to the instant of the formation of the universe--and possibly to a multiverse…
Why Time Is a Mystery
Begin your study of the physics of time with these questions: What is a clock? What does it mean to say that "time passes"? What is the "arrow of time"? Then look at the concept of entropy and how it holds the key to the one-way direction of time in…
What Is Time?
Approach time from a philosophical perspective. "Presentism" holds that the past and future are not real; only the present moment is real. However, the laws of physics appear to support "eternalism"--the view that all of the moments in the history of the universe are equally real.
