Urey also transformed his laboratory during the Cold War, introducing a new focus on the history of the earth and solar system and the origins of life. Beginning in the 1950s Urey's inner struggle led him to publicly call for a new synthesis of science and religion. Instead of the miraculous, he offered a grand view of the universe provided.

Harold C. Urey (1893-1981) was one of the most famous American scientists of the twentieth century. Born in rural Indiana, his evolution from small-town farm boy to scientific celebrity made him a symbol and spokesman for American scientific authority. Because he rose to fame alongside the prestige of American science, the story of his life.

Percobaan Miller-Urey. Percobaan Miller-Urey [1] (atau percobaan Urey-Miller) [2] adalah percobaan yang menyimulasikan keadaan Bumi purba dan menguji terjadinya abiogenesis. Lebih tepatnya, percobaan ini menguji hipotesis Alexander Oparin dan J. B. S. Haldane bahwa keadaan Bumi purba mendukung reaksi kimia yang dapat menyintesis senyawa.

Historia y biografía de Harold Clayton Urey
The Miller-Urey experiment was an experimental simulation conducted in 1953 that tested whether organic molecules could be formed from chemical reactions occurring between inorganic molecules thought to have been present early in Earth's history. To test Oparin and Haldane's ideas, Miller and Urey designed a closed experiment in a laboratory.

In 1952, Stanley Miller, then a graduate student at the University of Chicago, approached Harold Urey about doing an experiment to evaluate the possibility that organic compounds important for the origin of life may have been formed abiologically on the early Earth. The experiment was conducted using a custom-built glass apparatus ( Figure 1A.

The Miller-Urey experiment initially created at least five amino acids and some carbohydrates, which are both complex organic compounds. These compounds emerged out of less complex and inorganic.

Teori Evolusi Kimia Oparin, Harold Urey, dan Stanley Miller. Teori evolusi kimia secara umum menjelaskan bahwa satuan-satuan kompleks penyusun makhluk hidup seperti lipid, gula, asam amino dapat terbentuk dari kondisi-kondisi abiotik. Ada 3 tahapan terbentuknya senyawa organik menurut teori evolusi kimia, yakni: (1) Terbentuknya zat organik.

History: Dreaming of the bomb. In the 1920s, Urey was among a small group of chemists who collaborated closely with physicists. Working at Niels Bohr's Institute for Theoretical Physics at the University of Copenhagen, he kept abreast of developments in quantum mechanics. There, and on travels in Germany, he met the likes of Werner Heisenberg.
