Marking Time

Are We Alone - "Time's Mysteries Part I: Marking Time"

Time's a mystery, yet we've invented clever ways to capture it. From sundials to atomic clocks, trace the history of time-keeping. Also, discover the surprising accuracy of nature's dating schemes - from the decay of carbon to laying down tree rings. Plus, why the "New York minute," stretches to hours in Rio de Janeiro: cultural differences in the perception of time.
