Not just understand it well enough to say lots
of nifty words about it — well enough to start from the basic empirical
laws and principles and derive and demonstrate nearly the whole thing through the introductory classical level at the blackboard, without notes, as I do
several times a year in front
of several hundred very bright students a year, working with a team
of Ph.D. physicists who are my co-instructors (with perhaps a century
of teaching experience between us who, one would think, would correct my
errors if I made any egregious ones along the way).
At the Court
of Appeal, UBC alleged that the Tribunal had made
several errors of fact and
law, including in refusing to consider modifications
of the residency program as relevant to finding that disability was a factor in Dr. Kelly's adverse treatment and in considering both the procedural and substantive elements
of the duty to accommodate.
