+I began programming with Fortran, a common initiation for many physicists. The rise of NumPy and SciPy
+eventually drew me to the Python world. As my interest in Python waned, I turned to C++, but was quickly dissuaded by its aesthetic limitations,
+which lead me to the beauty of Lisp and Haskell. Despite some criticisms of these languages, the core features I value in them have their
+roots in APL ([[https://www.softwarepreservation.org/projects/apl/Books/APROGRAMMING%20LANGUAGE][A Programmin Language]]). Programming in Iversonian array languages is a delightful experience.
