SUMMARY:Exhibition:For All Ages Exhibit
DESCRIPTION:In the 19th century\, new ideas about childhood and education\, along with advances in printing like chromolithography\, made it possible to mass-produce games and toys. These were not only fun to play with but also taught practical skills and moral lessons. Learn about familiar and unique toys and board games throughout American history in the William L. Clements Library’s new exhibit\, “For All Ages” on view weekdays from 12-4 pm between October 3-January 5.\n\nEven though the objects are behind glass\, the co-curators have created an interactive way to explore the display. Visit the exhibit to participate in a scavenger hunt and win a prize!

SUMMARY:Lecture / Discussion:HET Brown Bag Seminar |  Log soft graviton theorem from BMS superrotation symmetry
DESCRIPTION:In four spacetime dimensions\, the soft graviton theorem exhibits a term that arises exclusively from one-loop diagrams and is logarithmic in the soft graviton energy. In this talk\, we demonstrate that this term\, known as the log soft graviton theorem\, can be derived as the Ward identity of BMS superrotation symmetry\, once long-range interactions are properly taken into account. We carry out a systematic analysis to all orders in the coupling and confirm that the log soft theorem is indeed one-loop exact.
