Professor Adrian Bejan traces his approach to science to growing up during a totalitarian Communist regime in Romania during the 1950s and 60s. Dr. Bejan witnessed the destruction of his parents, their generation, and the values they held dear. During this time, he learned to question in silence the difference between the truths spoken at home and the lies that filled the school and the street.

In response, Dr. Bejan found his best teachers were his parents and grandparents and today, in honor of them, he teaches students and readers to question everything, from scientific claims to opinions. In this lecture, he illustrates the method with examples from three topics of current interest: hierarchy, diversity, and innovation. Advances come from the few individuals with the courage to ask "Why?" and offer better ideas without fear. 

Dr. Bejan is a J. A. Jones Distinguished Professor of Mechanical Engineering at Duke University, a notable author, and a leading scientist in the field of thermodynamics. In his work, Freedom & Evolution, Dr. Bejan explores the relationship between freedom and evolution through the lens of physics and thermodynamics and notably grounds freedom in the observable, natural world.

This lecture was conducted at Thales Academy Rolesville Junior High-High School on March 8, 2024.
