Profs and Pints Philadelphia presents: “Finding the Cosmic Puzzle’s Missing Pieces,” a look at how the fields of astronomy and subatomic physics are working in tandem to shed light on the darkest parts of the universe, with Mark Trodden, professor of physics, co-director of the Center for Particle Cosmology, and associate dean for the natural sciences at the University of Pennsylvania. For most of the last century, physicists pushed our understanding of the microscopic world down to ever-smaller sizes, splitting the atom to reveal its inner workings and enable astonishing new discoveries, including, most recently, the Higgs particle. At the

(https://profs-and-pints-black-squirrel.ticketleap.com/climatescience/) .] We hear and read a lot about climate change and global warming, and it has become pretty hard to ignore the Philadelphia region’s wacky weather patterns with its recent freakily warm winters, vanishing snow, and late spring “heat domes.” Many of us, however, don’t have much of a grasp of the science explaining such developments and can’t answer questions such as: How do we really know
