Historicity And Ecological Restoration, Eric Desjardins
Historicity And Ecological Restoration, Eric Desjardins
Research Day (Arts & Humanities, FIMS, and Education)
Traditional ecological restoration often relies on ideals of reversibility and balance of nature. I suggest that we should change these for a path-dependent view of natural processes. This conceptual shift also invites for philosophical and methodological revisions, such as favouring “futuristic” dynamic goals and alternative state models.

Idealization In Scientific Explanation, Robert Batterman, Nicolas Fillion, Robert Moir, James Overton
Research Day (Arts & Humanities, FIMS, and Education)
Many phenomena pose interesting “fundamental” questions for both physics and philosophy of science. Understanding and explanation often seem to require non-Galilean, essential idealizations. But idealizations are false. This fact suggests that we need to give up on the view that truth is a necessary condition for explanation.

An Analytical And Numerical Treatment Of The Carter Constant For Inclined Elliptical Orbits About A Massive Kerr Black Hole, Peter Komorowski, Sree Ram Valluri, Martin Houde
WORLDiscoveries Research Showcase
In an extreme binary black hole system, an orbit will increase its angle of inclination (i) as it evolves in Kerr spacetime. We focus our attention on the behaviour of the Carter constant (Q) for near-polar orbits. The value of Q for bound orbits is non-negative; and an increase in Q corresponds to an increase in i. For a Schwarzschild black hole, the polar orbit represents the boundary between the prograde and retrograde orbits at which Q is at its maximum value. The introduction of spin (S = |J|/M2) to the massive black hole causes this boundary, or Abutment, to …
