Berkeley ranks among the world's top universities.A founding member of the Association of American Universities, Berkeley hosts many leading research institutes dedicated to science, engineering, and mathematics. The university founded and maintains close relationships with three national laboratories at Berkeley, Livermore and Los Alamos, and has played a prominent role in many scientific advances, from the Manhattan Project and the discovery of 16 chemical elements to breakthroughs in computer science and genomics. Berkeley is also known for political activism and the Free Speech Movement of the 1960s.Berkeley's athletic teams, which compete as the California Golden Bears primarily in the Pac-12 Conference, have won 107 national championships, and its students and alumni have won 223 Olympic medals (including 121 gold medals).Among its alumni, faculty and researchers, Berkeley has more Nobel laureates (107), Turing Award winners (25), Fields Medalists (14), and Wolf Prize winners (30) than any other public university in the nation; it is affiliated with 34 Pulitzer Prizes, 19 Academy Awards, and more MacArthur "Genius Grants" (108) and National Medals of Science (68) than any other public institution.

The Free Speech Movement (FSM) was a massive, long-lasting student protest which took place during the 1964–65 academic year on the campus of the University of California, Berkeley. The Movement was informally under the central leadership of Berkeley graduate student Mario Savio. Other student leaders include Jack Weinberg, Michael Rossman, George Barton, Brian Turner, Bettina Aptheker, Steve Weissman, Michael Teal, Art Goldberg, Jackie Goldberg and others.With the participation of thousands of students, the Free Speech Movement was the first mass act of civil disobedience on an American college campus in the 1960s. Students insisted that the university administration lift the ban of on-campus political activities and acknowledge the students' right to free speech and academic freedom. The Free Speech Movement was influenced by the New Left, and was also related to the Civil Rights Movement and the Anti-Vietnam War Movement. To this day, the Movement's legacy continues to shape American political dialogue both on college campuses and in broader society, influencing some political views and values of college students and the general public.
