The year 1947 in science and technology involved some significant events, listed below.
Maria Goeppert Mayer was a German-American theoretical physicist, and Nobel laureate in Physics for proposing the nuclear shell model of the atomic nucleus. She was the second woman to win a Nobel Prize in physics, the first being Marie Curie. In 1986, the Maria Goeppert-Mayer Award for early-career women physicists was established in her honor.

Harold Clayton Urey was an American physical chemist whose pioneering work on isotopes earned him the Nobel Prize in Chemistry in 1934 for the discovery of deuterium. He played a significant role in the development of the atom bomb, as well as contributing to theories on the development of organic life from non-living matter.
The year 1945 in science and technology involved some significant events, listed below.

The year 1941 in science and technology involved some significant events, listed below.
The year 1931 in science and technology involved some significant events, listed below.
Mildred Cohn was an American biochemist who furthered understanding of biochemical processes through her study of chemical reactions within animal cells. She was a pioneer in the use of nuclear magnetic resonance for studying enzyme reactions, particularly reactions of adenosine triphosphate (ATP).
The 1851 Research Fellowship is a scheme conducted by the Royal Commission for the Exhibition of 1851 to annually award a three-year research scholarship to approximately eight "young scientists or engineers of exceptional promise". The fellowship is open to all nationalities and fields of science, including physical or biological sciences, mathematics, applied science, and any branch of engineering. The fellowship can be held anywhere in the United Kingdom.
Jacob Bigeleisen was an American chemist who worked on the Manhattan Project on techniques to extract uranium-235 from uranium ore, an isotope that can sustain nuclear fission and would be used in developing an atomic bomb but that is less than 1% of naturally occurring uranium. While the method of using photochemistry that Bigeleisen used as an approach was not successful in isolating useful quantities of uranium-235 for the war effort, it did lead to the development of isotope chemistry, which takes advantage of the ways that different isotopes of an element interact to form chemical bonds.
This is a timeline of women in science, spanning from ancient history up to the 21st century. While the timeline primarily focuses on women involved with natural sciences such as astronomy, biology, chemistry and physics, it also includes women from the social sciences and the formal sciences, as well as notable science educators and medical scientists. The chronological events listed in the timeline relate to both scientific achievements and gender equality within the sciences.
In stable isotope geochemistry, the Urey–Bigeleisen–Mayer equation, also known as the Bigeleisen–Mayer equation or the Urey model, is a model describing the approximate equilibrium isotope fractionation in an isotope exchange reaction. While the equation itself can be written in numerous forms, it is generally presented as a ratio of partition functions of the isotopic molecules involved in a given reaction. The Urey–Bigeleisen–Mayer equation is widely applied in the fields of quantum chemistry and geochemistry and is often modified or paired with other quantum chemical modelling methods to improve accuracy and precision and reduce the computational cost of calculations.
