This week I began re-reading Hanif Kureishi's
Something to Tell You -- I really enjoyed it the first time, and the re-read is even more rewarding. His prose is so direct and shorn of any adornment, but it still thrills. Both Philip Roth and Kureishi are excellent at writing about the middle-aged. Incidentally, both are also very good at writing about psychoanalysis. Would definitely recommend this one.
I'm also reading Rhoad, Milauskas, and Whipple's
Geometry For Enjoyment and Challenge -- Never knew how rich the conceptual basis for even elementary geometry can be. That any figure can be thought of as specific arrangements of dots is particularly amazing. More so since, the "ideal" dot (as opposed to the one we make with a pencil) is itself a concept. The ideal dot has no dimension and doesn't exist in what we call the "real world."
