Jeffery Wright is a beloved physics teacher at Louisville Male Traditional High School in Louisville, KY. His wacky antics like holding fire in his hand and lying on a bed of nails with a cinder block on his chest while a student hits it with sledgehammer help his students learn a usually less entertaining subject.
Wright also does one lecture every year that leaves the biggest impact on his students. He tells about his son Adam who has rare disorder called Joubert syndrome, which prevents him from properly controlling his physical movement and has left him visually impaired and unable to talk.
Wright tells about his Adam using sign language to say, “Daddy, I love you” for the first time and how there is nothing more incredible to him. He explains to his class that the force that is more powerful than energy and entropy is love. Source: NY Times
