Suite (music) at the age of 23. In the late 19th century, Sibelius's "Karelia Suite" was written for the students of the Helsinki university. Brought on by Impressionism, the piano suite was reintroduced by early 20th-century French composers such as Ravel and Debussy. Debussy's "Pour le piano" is a suite in three movements, published in 1901, and his "Suite bergamasque", revised in 1905, is probably one of the most famous suites, especially the third movement, "Clair de Lune". Ravel is particularly well known for his "Miroirs" suite for piano and lesser known for "Le tombeau de Couperin", both requiring tremendous skill and
Lune of Hippocrates give the only constructible squarable lunes; in particular, there are no constructible squarable convex lunes. Lune of Hippocrates In geometry, the lune of Hippocrates, named after Hippocrates of Chios, is a lune bounded by arcs of two circles, the smaller of which has as its diameter a chord spanning a right angle on the larger circle. Equivalently, it is a non-convex plane region bounded by one 180-degree circular arc and one 90-degree circular arc. It is the first curved figure to have its exact area calculated mathematically. Hippocrates wanted to solve the classic problem of squaring the circle, i.e. constructing
