An exhibit entitled The Same and Not The Same, dealing with chirality and mirror images, is on display in the case across the hall from the mailboxes on the first floor of the Shain Research Tower. The display contains molecular models and mirrors in which their images can be seen. Observers are invited to examine the models, the mirrors, and the mirror images (including the observer's own images!) Also on display are several books related to mirrors and chirality, including Nobel laureate Roald Hoffmann's book of the same title as this exhibit. The exhibit features a contest involving identification of the models. The winner of the contest will receive a personally autographed copy of Professor Hoffmann's book.
