The Math Behind the Music
This chapter discusses how to vary a theme mathematically, and how not to mix mathematics and music.
Recursive Surreal Numbers
It is shown that the two effectivizations of the surreal number system via cuts and via sign sequences in fact yield different sets of surreals.
Fuzzy Recursion, RET's, and Isols
Fuzzy Regressivity and Retraceability
Polynomial-Time Analogues of Isolatedness
From Double Takes to Double Periods

How Mathematicians Know What Computers Can't Do
Leon Harkleroad writes that his alleged specialty is computability (recursion theory). But he can also be found working on the history of mathematics (focusing on the life and works of R6zsa P6ter)
