SC15 announces that noted science communicator and award-winning actor Alan Alda will discuss the role of science in our society and the intersection of science and computing as he delivers the keynote address November 17, 2015 in Austin, TX (USA). “High performance computing has a transformational impact on science in our society,” observes SC15 general chair Jackie Kern, University of Illinois at Urbana Champaign. “For decades scientists and engineers have relied on high performance computing to advance the state of the art in diverse fields ranging from healthcare and automotive safety to renewable energy. Computing is now fully integrated into the scientific discovery process, an equal partner with theory and experiment in improving the quality of life for all members of our global society. Mr. Alda’s focus on communicating the benefits of science to the public—and how we can all do this more effectively—makes him uniquely positioned to help SC continue to bridge the gaps in science understanding and highlight our role in the discovery process.” To read further, please visit http://sc15blog.blogspot.com/2015/08/science-advocate-and-emmy-award-winning.html.
