Problem: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
Following Planck's discovery, what was realized about values of physical action?

Answer: physical action cannot take on an arbitrary value


Problem: A traditional sport played in Tuvalu is kilikiti, which is similar to cricket. A popular sport specific to Tuvalu is Ano, which is played with two round balls of 12 cm (5 in) diameter. Ano is a localised version of volleyball, in which the two hard balls made from pandanus leaves are volleyed at great speed with the team members trying to stop the Ano hitting the ground. Traditional sports in the late 19th century were foot racing, lance throwing, quarterstaff fencing and wrestling, although the Christian missionaries disapproved of these activities.
What is the traditional sport on Tuvalu?

Answer: kilikiti


Problem: Chinese political philosophy dates back to the Spring and Autumn Period, specifically with Confucius in the 6th century BC. Chinese political philosophy was developed as a response to the social and political breakdown of the country characteristic of the Spring and Autumn Period and the Warring States period. The major philosophies during the period, Confucianism, Legalism, Mohism, Agrarianism and Taoism, each had a political aspect to their philosophical schools. Philosophers such as Confucius, Mencius, and Mozi, focused on political unity and political stability as the basis of their political philosophies. Confucianism advocated a hierarchical, meritocratic government based on empathy, loyalty, and interpersonal relationships. Legalism advocated a highly authoritarian government based on draconian punishments and laws. Mohism advocated a communal, decentralized government centered on frugality and ascetism. The Agrarians advocated a peasant utopian communalism and egalitarianism. Taoism advocated a proto-anarchism. Legalism was the dominant political philosophy of the Qin Dynasty, but was replaced by State Confucianism in the Han Dynasty. Prior to China's adoption of communism, State Confucianism remained the dominant political philosophy of China up to the 20th century.
