Inconsistent Mathematics, Reutersvärd, and Buddhism: An Interview with Chris Mortensen Inconsistent Mathematics, Reutersvärd, and Buddhism: An Interview with Chris Mortensen by Michael Lopresto Chris Mortensen is Emeritus Professor of Philosophy at the University of Adelaide. He thinks that the inconsistent hasn't been taken seriously enough in Western philosophy, that the masterpieces of Reutersvärd rub our noses in the inconsistent, and that Western philosophy and Buddhism are complementary. He's the author of Inconsistent Mathematics (1995) and Inconsistent Geometry (2010). Firstly, what made you get into philosophy?

Unhappy Truckers and Other Algorithmic Problems - Issue 3: In Transit When Bob Santilli, a senior project manager at UPS, was invited in 2009 to his daughter’s fifth grade class on Career Day, he struggled with how to describe exactly what he did for a living. Eventually, he decided he would show the class a travel optimization problem of the kind he worked on, and impress them with how fun and complex it was. The challenge was to choose the most efficient route among six different stops, in a typical suburban-errands itinerary. The class devised their respective routes, then began picking them over. But one girl thought past the question of efficiency. “She says, my mom would never go to the store and buy perishable things—she didn’t use the word perishable, I did—and leave it in the car the whole day at work,” Santilli tells me.

How to play Bayes' Theorem An Intuitive Explanation of Bayes' Theorem Bayes' Theorem for the curious and bewildered; an excruciatingly gentle introduction. Your friends and colleagues are talking about something called "Bayes' Theorem" or "Bayes' Rule", or something called Bayesian reasoning. Infinities in literature and mathematics by Jorge Alejandro Laris Pardo During this past month, I was having a conversation with a couple of friends who study Latin-American Literature, and I noticed that they were having a hard time understanding how a literary work can have infinite critical interpretations, while at the same time not all its interpretations are critical. Apparently they found this to be contradictory. I was shocked by their confusion, because to me the idea in question is almost self-evident.
