In this course we will seek to “understand Einstein,” especially focusing
on the special theory of relativity that Albert Einstein, as a 26-year-old
patent clerk, introduced in his so-called “miracle year” of 1905. Our goal
will be to go behind the myth-making and beyond the popularized presentations
of relativity in order to gain a deeper understanding of both Einstein
the person and the concepts, predictions, and strange paradoxes of his
theory. Some of the questions we will address include: How did Einstein
come up with his ideas? What was the nature of his genius? What is the
meaning of relativity? What’s “special” about the special theory of relativity?
Why did the theory initially seem to be dead on arrival? What does it mean
to say that time is the “fourth dimension”? Can time actually run more
slowly for one person than another, and the size of things change depending
on their velocity? Is time travel possible, and if so, how? Why can’t things
travel faster than the speed of light? Is it possible to travel to the
center of the galaxy and return in one lifetime? Is there any evidence
that definitively confirms the theory, or is it mainly speculation? Why
didn’t Einstein win the Nobel Prize for the theory of relativity?

Students may choose one of three approaches to the course: a more quantitative
approach, a more qualitative approach, or an auditing approach. The more
quantitative approach will include weekly problem sets, while the more
qualitative approach will include a creative project relating to the young
Einstein and/or the special theory of relativity.

**Week One (Einstein in Context):** Einstein quotes of the week; a thought
experiment involving relativity; physics and Einstein circa 1900.

**Week Two (Events, Clocks, and Reference Frames):** Einstein quotes
of the week; synchronizing clocks; the famous June 1905 paper; thinking
more deeply about events and observers; understanding inertial frames of
reference; spacetime diagrams; the Galilean transformation; Einstein's
starting point: the two postulates.

**Week Three (Ethereal Problems and Solutions):** Einstein quotes of
the week; a few words about waves; the luminiferous ether; the Michelson-Morley
experiment vs. stellar aberration; how do you solve a problem like the
ether?; the solutions of Fitzgerald, Lorentz, Poincare, and Einstein.

**Week Four (The Weirdness Begins):** Einstein quotes of the week; the
light constancy principle; time and length are suspect; what isn't suspect;
exploring the Lorentz factor; the miracle of the muon.

**Week Five (Spacetime Switching):** Einstein quotes of the week; the
Lorentz transformation; leading clocks lag; the ultimate speed limit.

**Week Six (Breaking the Spacetime Speed Limit?): **Einstein quotes
of the week; spacetime diagrams revisited; regions of spacetime; cause
and effect, or vice versa?; faster than light paradoxes.

**Week Seven (Paradoxes to Ponder): **Einstein quotes of the week;
the pole-in-the-barn paradox; the spaceships-on-a-rope paradox; how length
contraction actually works; the twin paradox.

**Week Eight (To the Center of the Galaxy and Back): **Einstein quotes
of the week; traveling the galaxy in one lifetime; the reception of relativity;
Einstein's Nobel Prize and the nature of genius; relativity beyond science.
