Scott started his career as a Mission Operations Analyst, performing tens of thousands of physics-based computer simulations of the robotic arms on the International Space Station, and providing real-time support to space shuttle missions, over a period of more than 7 years. Always passionate about teaching, Scott conducted some astronaut training at the Canadian Space Agency, and then transitioned to teaching physics at Vanier College in Montreal. After more than 3 years of teaching, Scott retired from full-time employment to spend more time with his growing family. Scott's teaching bug persisted, and Scott soon started tutoring college physics students and creating YouTube videos to help explain concepts at the right level for introductory college physics.
