AO: Tilley notes that it was not until the nineteenth century, and particularly the period after 1850, that scientific institutions and ideologies began to attain worldwide preeminence. While this worldwide preeminence is related to Europe’s pursuit of global colonialism, she notes it is also a result of factors including the greater organization of scientific congresses; shared nomenclature and methods; professionalization of the biosciences and field sciences; greater circulation of international scientific journals, and the standardization of laws regulating and defining science.
