Harvey Reall, Kitty Furguson, and Vijay Balsubramanian reflect on the life and legacy of physicist Stephen Hawking. Reall, professor of theoretical physics at Cambridge University, discusses what science has lost and highlights Hawking's contributions to science despite his gradual paralysis due to amyotrophic lateral sclerosis (ALS). Ferguson, author of "Stephen Hawking: an unfettered mind," emphasizes Hawking's dedication to making complex scientific topics more accessible and simple so ordinary people could learn and understand his work. Ferguson recalls Hawking's enthusiasm, humor, and joy in everything he did, sharing stories about moments they had together. Balasubramanian, professor of theoretical physics at the University of Pennsylvania, talks about his interactions with Hawking and the inspiration Hawking gave to many around the world. Balasubramanian emphasizes that Hawking was famous because of his courage and that anyone can make a difference if they have the courage to do it.
