Science policy is concerned with the allocation of resources for the conduct of science towards the goal of best serving the public interest. Topics include the funding of science, the careers of scientists, and the translation of scientific discoveries into technological innovation to promote commercial product development, competitiveness, economic growth and economic development. Science policy focuses on knowledge production and role of knowledge networks, collaborations, and the complex distributions of expertise, equipment, and know-how. Understanding the processes and organizational context of generating novel and innovative science and engineering ideas is a core concern of science policy. Science policy topics include weapons development, health care and environmental monitoring. Science policy thus deals with the entire domain of issues that involve science. A large and complex web of factors influences the development of science and engineering that includes government science policymakers, private firms (including both national and multi-national firms), social movements, media, non-governmental organizations, universities, and other research institutions. In addition, science policy is increasingly international as defined by the global operations of firms and research institutions as well as by the collaborative networks of non-governmental organizations and of the nature of scientific inquiry itself. History State policy has influenced the funding of public works and science for thousands of years, dating at least from the time of the Mohists, who inspired the study of logic during the period of the Hundred Schools of Thought, and the study of defensive fortifications during the Warring States period in China. General levies of labor and grain were collected to fund great public works in China, including the accumulation of grain for distribution in times of famine, for the building of levees to control flooding by the great rivers of China, for the building of canals and locks to connect rivers of China, some of which flowed in opposite directions to each other, and for the building of bridges across these rivers. These projects required a civil service, the scholars, some of whom demonstrated great mastery of hydraulics. In Italy, Galileo noted that individual taxation of minute amounts could fund large sums to the State, which could then fund his research on the trajectory of cannonballs, noting that "each individual soldier was being paid from coin collected by a general tax of pennies and farthings, while even a million of gold would not suffice to pay the entire army."
