The Man Who Accidentally Killed The Most People In History

Veritasium

Summary

Este vídeo narra la historia de Thomas Midgley Jr., el inventor que, irónicamente, causó un daño ambiental y humano sin precedentes. Midgley introdujo el plomo tetraetilo en la gasolina para evitar el 'detonado' en motores, lo que provocó una crisis mundial de salud pública debido a la toxicidad del plomo. Además, desarrolló los CFC para refrigeración, causando el agujero en la capa de ozono. El vídeo contrapone su legado con el trabajo de Clair Patterson, un científico que dedicó su vida a medir la edad de la Tierra y a desenmascarar la contaminación por plomo, a pesar de la fuerte oposición de la industria. Es una reflexión sobre cómo las decisiones técnicas pueden tener consecuencias globales catastróficas y cómo la ciencia honesta es crucial frente a los intereses comerciales.

Transcript excerpt

One single scientist created three inventions that accidentally caused the deaths of millions of people, including himself. Not only that, they decreased the average intelligence of people all around the world, increased crime rates, and caused two completely separate environmental disasters that we are still dealing with today. Part of this video is sponsored by Wren. More about them at the end of the show. In 1944, as a young chemist who had just finished his master's, Clair Patterson went to work on the Manhattan Project, building the first nuclear weapons. His job was to concentrate uranium 235, the fissile fuel for bombs, from the much more common uranium 238. And this required huge machines, mass spectrometers, which separated the two types of uranium by their slight difference in mass. After the war, Patterson went back to grad school to get his PhD. He picked a research project t…
