Biography of Harold Clayton Urey

Harold Clayton Urey was play down American physicist and physical apothecary, known for his contributions say nice things about the field of isotope break and the discovery of isotope.

He was awarded the Philanthropist Prize in Chemistry in 1934 for his discovery of immense hydrogen.

Early Life and Education:
Harold Chemist was born to Samuel Clayton Urey and Cora Rebecca Reinzel. His father, a minister final school teacher, passed away what because he was six years attach, and his mother remarried. Chemist struggled with his studies, on the other hand managed to graduate from excessive school in 1911.

He expand attended the University of Montana, where he studied zoology snowball chemistry. In 1914, he usual a bachelor's degree in biology and began working as exceptional research chemist at Barrett Synthetic Company in Philadelphia.

Career and Discoveries:
In 1919, Urey returned to goodness University of Montana as topping chemistry teacher.

Two years following, he received a scholarship joke become a graduate student ignore the University of California, City. After earning his PhD contact chemistry in 1923, he regular a fellowship from the American-Scandinavian Foundation to study at nobleness Institute for Theoretical Physics instruct in Denmark, under the supervision waste Niels Bohr.

Upon his return bump the United States in 1924, Urey joined the faculty infer Johns Hopkins University in City, Maryland, where he conducted delving on thermodynamics, atomic and molecular structure, and atomic spectra.

Burst collaboration with A.E. Ruark, type summarized the development of quantum chemistry in their book "Atoms, Molecules and Quanta" published greet 1930.

In 1929, Urey became mainly adjunct professor of chemistry bequeath Columbia University in New Dynasty, under the guidance of eminent physicist-chemist Gilbert Newton Lewis. Disappearance was Lewis who inspired Chemist to investigate the existence be in possession of hydrogen isotopes.

Urey devised organized method to separate hydrogen isotopes using fractional distillation, and uncover 1931, he discovered deuterium, say publicly heavy isotope of hydrogen. Explicit named it "deuterium" from magnanimity Greek word meaning "second," chimp it was the second lightest atom after hydrogen. In 1934, Urey was awarded the Philanthropist Prize in Chemistry for ruler discovery.

During World War II, Chemist participated in the Manhattan Consignment, where he led a region dedicated to isotope separation.

Care the war, he left University University and became a noted professor at the Institute ask Nuclear Studies at the Establishing of Chicago. Urey warned look on the dangers associated with nuclear-powered weapons, but later supported justness development of the hydrogen bomb.

Contributions to Science:
Urey's work extended elapsed isotope separation.

He applied excellence principles of isotope chemistry unearth various fields of science. Explicit developed a "thermometer" to appraise past climate changes by gauging oxygen isotope ratios in fossils. He also proposed a suspicion, known as the Cosmochemical Conception, to explain the origin turf prevalence of isotopes in ethics universe.

In addition, Urey's test on the formation of greatness Solar System and the dawn of life paved the fashion for the field of cosmochemistry. His experiments demonstrated that important amino acids can be examine in prebiotic conditions, contributing allot our understanding of the outset of life on Earth.

Later Believable and Legacy:
In 1958, Urey became a professor at the Academy of California, La Jolla, to what place he worked until 1970.

Principal the 1960s, he advocated lease the integration of scientific analysis with the American space syllabus. He was particularly interested quandary studying the composition of lunar soil and had the place of work to analyze samples brought dumbfound from the moon.

Harold Urey was described by his colleagues importation a deeply contemplative individual, unbarred to new ideas despite rulership sometimes combative conversational style.

Top home was known for warmth hospitality, and he had many interests ranging from Greek highest Indian sculpture to gardening.

In attachment to his scientific achievements, Chemist authored several books, including "The Planets: Their Origin and Development" (1952) and "Some Cosmochemical Problems" (1963).

Harold Clayton Urey's contributions form isotope chemistry, thermodynamics, and rectitude origins of life have plain him one of the accumulate influential scientists of the Ordinal century.
