Can pets predict earthquakes? Do quakes happen more often at certain times of the day or year? And could a really big one mean the end of California? Exploratorium geologist Eric Muller separates earthquake fact from fiction. Relive the Loma Prieta quake with our photographer, Amy Snyder, who was caught in an outhouse at the beach. Why didn't it, or any San Francisco skyscapers, collapse? Join Exploratorium geologist Eric Muller on a tour of world-famous geological features to be found in the national parkland just north of the Golden Gate bridge. Explore how Mars’s gravity and geology would affect rock climbers, with the Exploratorium's Dr. Paul Doherty. In preparation for the 2004 landing of the Mars Exploration Rovers, NASA engineers and scientists tested their remote operation procedures using a rover called FIDO (field integrated design & operations rover). Our remote team traveled to the desert test site to see what they learned in the desert and what they hoped to learn on Mars. In 1963 Benoit Mandelbrot introduced the fractal concept. Fractals are shapes or behaviors that have similar properties at all levels of magnification. Just as the sphere is a concept that unites raindrops, basketballs and Mars, so fractal is a concept that unites clouds, coastlines, plants and strange attractors.
Dr. Mandelbrot dropped in for a visit during our 2001 series of webcasts about Antarctica. We took some time out from the freezing cold to interview him.
