This session will compare and contrast the history, examine the contemporary organization and discuss the future value of academies of science as bridges from science to society. Owing their origin to the "Akademia" of Plato, academies of science have developed worldwide as organizations that establish and maintain criteria for the methods and soundness of research and scholarly activities; recognize scholarship; disseminate and archive centuries of knowledge; provide a common meeting ground for discussion of cutting-edge research; provide advice to governmental agencies; foster science, technology, engineering, and mathematics (STEM) education; and engage in public outreach to benefit society. Academies of science have earned respect from the media, the public, and, in general, the worldwide academic community. Being an Academy Fellow distinguishes one in the academic world and to the public. American prototypical academies include the American Academy of Arts and Sciences and the National Academies. Most academies include disciplinary divisions or sections, and some now embrace interdisciplinary functions directed at global issues such as climate change, disease, energy, and the development of human capital. Some include arts and letters. Worldwide, more than 250 academies of science exist, including over 40 state and municipal academies in the United States. Some include arts and letters. The Inter-Academy Council organizes academies internationally.
