3-sphere two 3-balls. This construction is analogous to a construction of a 2-sphere, performed by gluing the boundaries of a pair of disks. A disk is a 2-ball, and the boundary of a disk is a circle (a 1-sphere). Let a pair of disks be of the same diameter. Superpose them and glue corresponding points on their boundaries. Again one may think of the third dimension as temperature. Likewise, we may inflate the 2-sphere, moving the pair of disks to become the northern and southern hemispheres. After removing a single point from the 2-sphere, what remains is homeomorphic to the Euclidean
Half a Life (memoir) to the death of Celine Zilke, a classmate, followed by a court case (this is America). Simultaneously, however, there is redemption. Crystal, and with many facets, Half a Life deserves celebration." In the Chicago Tribune, critic Elizabeth Taylor called it "a book that inspires admiration, sentence by sentence...This is memoir in its finest form."
