ScriptPhD.com’s coverage of the World Science Festival in New York City continues towards the physics and mathematics realm. Day 3 events on Friday included an intimate discussion about astrophysics and the new James Webb Telescope, set to replace Hubble in June of 2014, a panel about hearing and visualizing gravity with Albert Einstein’s modern successors, and a panel about the very limits of our understanding of science—the line between what we do and don’t (or can’t) know—and its bridge to culture and art. Contributions to our coverage were done by New York City science writers Jessica Stuart and Emily Elert. Synopses and pictures of three extraordinary panels with the premier scientists of our time under the “continue reading” cut.
