Cinema of the United StatesThe cinema of the United States, consisting mainly of major film studios (also known metonymously as Hollywood) along with some independent films, has had a large effect on the global film industry since the early 20th century. The dominant style of American cinema is classical Hollywood cinema, which developed from 1910 to 1962 and is still typical of most films made there to this day. While Frenchmen Auguste and Louis Lumière are generally credited with the birth of modern cinema, American cinema soon came to be a dominant force in the emerging industry.
Basic reproduction numberIn epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), of an infection is the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. The definition assumes that no other individuals are infected or immunized (naturally or through vaccination).
Rosalind Franklin'Rosalind Elsie Franklin' (25 July 1920 16 April 1958) was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. Although her works on coal and viruses were appreciated in her lifetime, Franklin's contributions to the discovery of the structure of DNA were largely unrecognized during her life, for which Franklin has been variously referred to as the "wronged heroine", the "dark lady of DNA", the "forgotten heroine", a "feminist icon", and the "Sylvia Plath of molecular biology".
