When an injury ended Calvin Mackie's NBA daydream, he was left with nothing to fall back on. Only one college was willing to take a chance on him because of his low SAT scores. Through sheer determination and outside-the-box thinking, Mackie has triumphed, failed, and triumphed again in the engineering field. Years later, when Tulane University ended his career in academia by shutting down their engineering department in the wake of Hurricane Katrina, Mackie rebounded again, transforming himself into an alternative energy business mogul and motivational speaker. With his message of success through STEM, this speech is a must-see for students, engineers, entrepreneurs, and scientists striving to excel in today's competitive environment.
