MU may refer to:

Mu (letter)

Mu (uppercase Μ, lowercase μ; Ancient Greek , Modern Greek μι or μυ ) is the 12th letter of the Greek alphabet. In the system of Greek numerals it has a value of 40. Mu was derived from the Egyptian hieroglyphic symbol for water (????), which had been simplified by the Phoenicians and named after their word for water, to become(mem). Letters that arose from mu include the Roman M and the Cyrillic М.

Mu (lost continent)

Mu is the name of a suggested lost continent whose concept and name were proposed by 19th-century traveler and writer Augustus Le Plongeon, who claimed that several ancient civilizations, such as those of Egypt and Mesoamerica, were created by refugees from Mu—which he located in the Atlantic Ocean. This concept was popularized and expanded by James Churchward, who asserted that Mu was once located in the Pacific.

The existence of Mu was already being disputed in Le Plongeon's time. Today scientists dismiss the concept of Mu (and of other alleged lost continents such as Lemuria) as physically impossible, arguing that a continent can neither sink nor be destroyed in the short period of time required by this premise. Mu's existence is now considered to have no factual basis.

Mu (negative)

The Japanese and Korean term mu or Chinese meaning "not have; without" is a key word in Buddhism, especially Zen traditions.

Mu (rocket family)

The Mu, also known as M, was a series of Japanese solid-fuelled carrier rockets, which were launched from Uchinoura between 1966 and 2006. Originally developed by Japan's Institute of Space and Astronautical Science, Mu rockets were later operated by Japan Aerospace Exploration Agency following its merger with ISAS.

Mu (kana)

, in hiragana, or in katakana, is one of the Japanese kana, which each represent one mora. The hiragana is written with three strokes, while the katakana is written with two. Both represent .

In the Ainu language, ム can be written as small ㇺ, which represents a final m sound. This, along with other extended katakana, was developed by Japanese linguists to represent Ainu sounds that do not exist in standard Japanese katakana.
