Governments and journalists tell us that though Chernobyl was “the worst nuclear disaster in history,” a reassuringly small number of people died (44) and nature recovered. Yet, drawing on a decade of fine-grained archival research and interviews in Ukraine, Russia and Belarus, this talk uncovers a much more disturbing story—one in which radioactive isotopes caused hundreds of thousands of casualties. Scores of Soviet scientists, bureaucrats and civilians documented stunning increases in cases of birth defects, child mortality, cancers and a multitude of prosaic diseases, which they linked to Chernobyl. Worried that this evidence would blow the lid on the effects of massive radiation release from weapons testing during the Cold War, international scientists and diplomats tried to bury or discredit it. A haunting revelation of how political exigencies shape responses to disaster, Kate Brown's Manual for Survival makes clear the irreversible impact on every living thing not just from Chernobyl, but from eight decades of radiation from nuclear energy and weaponry.
Catherine Pfaff of Queen's University will deliver the final colloquium of the semester, titled "Symmetries, Groups & How They Interact."
Abstract: "The symmetries of a polygon form a group. This group acts on the polygon by rotating it and flipping it. This basic idea of studying a group as symmetries of an object extends far beyond polygons. Through a myriad of colorful pictures, I will introduce the notion of a group, some of my favorite examples and then examples of the interplay between these groups and various geometric objects. No advanced mathematical knowledge will be assumed, and of course we will also play with doughnuts!"
Refreshments will be served at 4 p.m. in Seeley Mudd 208.
A safe space for five-college students who identify along either the asexual or aromantic spectrum, or who are questioning, to share and celebrate their identities. Cheese fondue and cake will be served. The conversation will focus on a community brainstorm on what an ace/aro support group can look like!
