1. Released in 2012, this 52-minute public television documentary reveals the motivations, struggles and ultimate triumphs of the people designing and building the most elaborate ground-based astronomical observatory ever, the Atacama Large Millimeter/submillimeter Array (ALMA). The program documents some of the first observations made by the telescope, foreshadowing the scientific rewards that will be its heritage. Filmed on three continents--and at altitudes ranging from sea level to 16,500 feet--the film features breathtaking views of Chile's remote Atacama Desert, and demonstrates the lengths to which humans will go to understand the universe they call home.

    OFFICIAL SELECTION: 2013 Richmond International Festival of Film.

    "The animation and graphics are well done...good interview subjects; clean cgi, pacing that isn't so fast you miss important facts, or too slow... and very good videography. Simply put, this is a solid public television program." - P3PublicMedia.com

  2. Bruce Buffett presents a public talk at UC Berkeley on July 17, 2010, as part of the Science@Cal Lecture Series described at http://scienceatcal.berkeley.edu/lectures

    Many of the planets in the solar system have internally generated magnetic fields. All of these fields are produced by the motion of an electrically conducting fluid in the interior, although the details vary from planet to planet. Historical observations of the magnetic field on Earth show that the field is continually changing on time scales as short as a few years. Earth's magnetic field also exhibits spontaneous polarity reversals, which cause the north and south magnetic poles to flip. The mechanism for reversals is not well understood, but geological records suggest that the onset of reversals is accompanied by a sudden reduction in the field strength. A strong field re-emerges from the interior as the new polarity is established. In this presentation I will discuss the origin of planetary magnetic fields. I will also speculate about the current decline in Earth's field, which has prompted some researchers to suggest that the field is entering the next reversal.

    Bruce Buffett is a Professor of Geophysics in the Department of Earth & Planetary Science at the University of California, Berkeley. He received his PhD in Geophysics from Harvard University and was a Research Fellow at the University of Cambridge. He moved the University of California in 2008 after holding a faculty appointment at the University of Chicago.
