In these archived webcasts from inside the American Association for the Advancement of Science (AAAS) exhibition hall, watch as Exploratorium senior scientist Tom Humphrey challenges some of the top scientists in the world to explain the phenomena behind selected exhibits from the museum floor. In this webcast: the String Squirter exhibit
as explained by physicist and Nobel laureate Leon Lederman What does it mean to find the Higgs Boson at CERN? Hear how this elusive particle could change our understanding of physics. Follow CERN's Mission Impossible team as they race against the clock to collect all they need to bring antihydrogen back to CERN's webcast headquarters. Scientists at CERN in Switzerland explain to the Exploratorium's San Francisco audience why preparing for antimatter experiments is like arranging a marriage. Making antihydrogen is no easy matter. Researchers at CERN show the Exploratorium's Melissa Alexander and Tom Humphrey where positrons live and how they keep them as cold as deep space. What is antimatter and why are scientists studying it? How is the world's largest particle accelerator constructed? The Exploratorium's Rob Semper talks about how science is done at CERN and answers questions about antimatter from the Exploratorium's Webcast audience. A behind-the-scenes look at how the world's only antimatter factory works, complete with live footage from CERN and a virtual reality tour of the antimatter decelerator. In this Webcast, Rob Semper and Ron Hipschman talk with Melissa Alexander and Thomas Humphrey, who join them virtually from Switzerland.
