O Erro de Cálculo Que Destruiu Hiroshima — E o Físico Que Nunca Se Perdoou

On August 6, 1945, a single bomb wiped an entire city off the map. Behind the destruction lay physics—equations, calculations, chain reactions. And there were physicists who spent the rest of their lives carrying the weight of what they had created. Some never recovered. Some never forgave themselves. And one of them made a miscalculation that made everything even more devastating than anyone had predicted. In this video, you'll understand how nuclear fission works and why it releases terrifying energy; what E=mc² really means when you convert mass into pure destruction; how the Manhattan Project brought together the greatest minds in 20th-century physics in a New Mexico desert; what miscalculation physicists made in predicting the bomb's destruction radius; how Richard Feynman suffered an emotional breakdown after Hiroshima and took weeks to be able to work again; why Leo Szilard organized a petition from 70 physicists asking Truman not to use the bomb on civilian cities—and was completely ignored—and how Oppenheimer was destroyed by the very government he served, losing his security clearance in a hearing poisoned by Cold War paranoia. If you want to go beyond the facts and understand the mental and ethical stance of those who do science with integrity, I highly recommend the book "The Feynman Secret: How Curiosity Led to Genius Discoveries". This video shows how Feynman navigated between intellectual wonder and moral responsibility—essential reading for anyone who takes scientific thought seriously.
