Carlos Bovell

Carlos Bovell

Carlos has been a public high school teacher for nearly twenty years. While earning his math degree at the College of New Jersey, he liked meeting during professors’ office hours to discuss intractable problems, which led them to ponder other unanswerable questions: What is mathematics? Can mathematical objects be known? Some faculty suggested that he pursue philosophy alongside math, a suggestion culminating in Toronto where he successfully defended a master’s thesis: “Rhetoric More Geometrico in Proclus’ Elements of Theology and Boethius’ De Hebdomadibus.” Carlos also completed an MS degree in mathematical computer science at Rutgers University-Camden and graduate study in computer science at the New Jersey Institute of Technology. Among his publications are a book entitled, Ideas at the Intersection of Mathematics, Philosophy and Theology, and an article entitled, “The Mathematician Is Not Really the Pure Theoretician but Only the Ingenious Technician.”
