Easter IslandEaster Island (Rapa Nui; Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called moai, which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island.
Moment of inertiaThe moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rate of rotation.
American exceptionalismAmerican exceptionalism is the belief that the United States is either distinctive, unique, or exemplary compared to other nations. Proponents argue that the values, political system, and historical development of the U.S. are unique in human history, often with the implication that it is both destined and entitled to play a distinct and positive role on the world stage. It originates in the observations and writings of French political scientist and historian Alexis de Tocqueville, most notably in his comparison of the United States with Great Britain and his native France.
