Faster than Light? Past, Future, and Elsewhere
Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? Finally, why is it that nothing can go faster than light?
Quantum Uncertainty - Farewell to Determinism
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?
Muons and Time-Traveling Twins
As a dramatic example of what relativity implies, you will consider a thought experiment involving a pair of twins, one of whom goes on a journey to the stars and returns to Earth younger than her sister!
Earth, Ether, Light
Review the famous Michelson-Morley experiment, which was designed to detect the motion of Earth relative to a conjectured ether wind that supposedly pervaded all of space. The failure to detect any such motion revealed a deep-seated contradiction at the heart of physics.
Electromagnetic Induction
Probe one of the most fascinating phenomena in all of physics, electromagnetic induction, which shows the direct relationship between electric and magnetic fields. In a demonstration with moving magnets, see how the relative motion of a magnet and an electric conductor induces current in the conductor.
A Problem of Gravity
Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime.
The Clockwork Universe
Isaac Newton was born in 1642, the year that Galileo died. You'll learn how he built on the work of Galileo and Kepler, developing the three laws of motion and the concept of universal gravitation. You'll learn why Newton's laws suggest a universe that runs like a clock.
Keeping Time
How do we measure the passage of time? Discover that practical concerns have driven the search for more and more accurate clocks. In the 18th century, the problem of determining longitude was solved with a timepiece of unprecedented accuracy. Today's GPS navigation units rely on clocks accurate to a billionth…
What about E=mcÂ˛ and Is Everything Relative?
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…
Einstein's Relativity and the Quantum Revolution - Modern Physics for Non-Scientists, 2nd Edition
"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these twenty-four 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…
Special Relativity
Discover the startling consequences of Einstein's principle of relativity: that the laws of physics are the same for all observers in uniform motion. One result is that the speed of light is the same for all observers, no matter what their relative motion: an idea that overturns the concept of…
Wave or Particle?
In the 1920s physicists established that light and matter display both wave- and particle-like behavior. Probe the nature of this apparent contradiction and the meaning of Werner Heisenberg's famous uncertainty principle, which introduces a fundamental indeterminacy into physics.
