Word of Mouth wishes you a happy Daylight Saving Time! (Can you believe it's this Sunday already?) But why exactly does the practice of changing our clocks even exist?

Imagine a four-wheeled robot, rolling slowly over frozen landscapes, equipped with high-tech sensors, and funded by NASA . You’re imagining a robot named Yeti, a polar rover designed by a team of Dartmouth Engineering students. Yeti has ground penetrating radar, and helps scientists in Antarctica and Greenland detect and map dangerous and possibly deadly crevasses before manned expeditions. Laura Rayis professor of engineering at Dartmouth College and Yeti project leader; she joined us earlier to discuss the new technology.
