I gave the following talk at the New York State Psychiatric Institute in New York City October 17 as part of a Festschrift for my father, and collaborator, Rodrick Wallace. A Festschrift is a symposium held–and a book published–in honor of a scholar, often on his or her 70th birthday. As opposed to a Gedenkschrft, held in memoriam (though there are some scholars who deserve the latter long before they’ve left for the great e-journal server in the sky).
I’ll start off with an old joke about Rod, in the de rigueur Boston accent. The joke runs like this: Equation 1. Equation 2. Equation 3. “We can see here an apartheid state entrains both oppressor and oppressed into a synergy of plagues.”
Equation 4. Equation 5. Equation 6. “It follows then that public health can be saved from a catastrophic vortex if and only if we smash the apartheid state.”
All kidding aside, we would make a mistake assuming Rod’s conclusions arise from his formalisms alone or—winky wink—vice versa. Instead, we should say they arise “and vice versa” and honestly so. Or better yet, inextricably so.
That’d be shocking if only because it would imply cultural and political precepts underlie mathematical mechanics. That the field’s formalisms are as much historical objects as many of the phenomena they address, as a number of commentators, including Wittgenstein and the ethnomathematicians, have ventured.
