In response to Stephen Colbert, FAU professor says 'spice it up'
A research professor gives a ''shout out'' to comedian Stephen Colbert. His motivation? Colbert previously referred to mathematical equations as the devil's sentences and an unnatural commingling of letters and numbers - the worst being the quadratic equation - an infernal salad of numbers, letters and symbols. In response, the professor suggests that mathematics education needs to be enlivened so that students will recognize that this discipline is not merely a necessary evil, but a vibrant, exciting and fascinating subject.
