Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei and
These droplets would "grow" by fusion with other droplets, and "reproduce" through fission into daughter droplets, and so have a primitive metabolism in which factors that promote "cell integrity" survive, and those that do not become extinct. Many modern theories of the origin of life still take Oparin's ideas as a starting point.
Otto Hahn (German: [ˈɔtoː ˈhaːn] ⓘ; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the field of radiochemistry.He is referred to as the father of nuclear chemistry and discoverer of nuclear fission, the science behind nuclear reactors and nuclear weapons.
Spontaneous fission (SF) is a form of radioactive decay in which a heavy atomic nucleus splits into two or more lighter nuclei. In contrast to induced fission, there is no inciting particle to trigger the decay; it is a purely probabilistic process.
Enrico Fermi was born in Rome, Italy, on 29 September 1901. [3] He was the third child of Alberto Fermi, a division head in the Ministry of Railways, and Ida de Gattis, an elementary school teacher. [3] [4] [5] His sister, Maria, was two years older, his brother Giulio a year older.

He developed methods for the dating of the age of minerals and other inorganic substances based on the half-life of radioactive elements and the enrichment of decay products. Strassmann and Ernst Walling developed the rubidium-strontium method of radiometric dating in 1936 and 1937, and Strassmann continued this work in 1942 and 1943.
