Imagine this: You can fit a 10 m pole in a barn half the size. Your twin is now 10 years older than you, but you didn't use a time machine. And no matter how fast you run, you can never reach the speed of light. How can you explain these scenarios? In this 5-hour, two day seminar, we use thought experiments like these and other tools to explore Einstein's theory of special relativity. We introduce Einstein's two postulates and explore the counterintuitive effects of time dilation, length contraction, and relativity of simultaneity. The class concludes with a look at spacetime diagrams and several challenging paradoxes of relativity.
