National Academy of Sciences Quote

The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).
As a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field in the United States. Members of the National Academy of Sciences serve pro bono as "advisers to the nation" on science, engineering, and medicine. The group holds a congressional charter under Title 36 of the United States Code.
Congress legislated and President Abraham Lincoln signed an Act of Congress (1863) establishing the National Academy of Sciences as an independent, trusted nongovernmental institution, created for the purpose of "providing independent, objective advice to the nation on matters related to science and technology [and] to provide scientific advice to the government 'whenever called upon' by any government department." This objective gave the academy the purpose of enriching and providing resources to any part of the federal government—rather than serving a single branch or executive agency, in contrast to the Library of Congress or many entities that report to the President. The goal was somewhat unusual at the time, and also different than other knowledge based entities serving a branch of government, such as the Library of Congress. The academy receives no compensation from the government for its services.
