Kavli Lecture: David Spergel

With support from the Kavli Foundation, the science program at every AAS meeting gets under way on Monday morning with the Kavli Foundation Lecture by a distinguished astronomer. In Boston the honor went to David N. Spergel (Princeton University), whose presentation was entitled "New Probes of Dark Energy." Spergel was introduced by AAS President David Helfand (Quest University Canada) and made news with his biting criticism of the BICEP2 project's claimed detection of the signature of gravitational waves from inflation.
