On Time

Time is at once familiar and confounding. After eighteen years (568 million seconds) of existence, you know it intimately. But what is time, really? The truth is, we don’t know. Time doesn’t even appear in the most fundamental laws of physics. In this course we explore the history of time-keeping from mechanical clocks to atomic clocks, human perceptions of time, Einstein’s theory of relativity, and present-day theories on time. Readings include Longitude (Dava Sobel), Simply Einstein (Richard Wolfson), The Order of Time (Carlo Rovelli) and selected articles from neuroscience. We will also look back in time using the College Observatory. 3 hrs. sem.
