A math circle is an extracurricular activity intended to enrich students' understanding of mathematics. The concept of math circle came into being in the erstwhile USSR and Bulgaria, around 1907, with the very successful mission to "discover future mathematicians and scientists and to train them from the earliest possible age".

This list ranks the top 150 U.S. cities (incorporated places) by 2024 land area. Total areas including water are also given, but when ranked by total area, a number of coastal cities appear disproportionately larger. San Francisco is an extreme example: water makes up nearly 80% of its total area of 232 square miles (601 km 2).
The area of an equilateral triangle with edge length is =. The formula may be derived from the formula of an isosceles triangle by Pythagoras theorem : the altitude h {\displaystyle h} of a triangle is the square root of the difference of squares of a side and half of a base . [ 3 ]
The circle will shrink and eventually collapse down to a point. If an initial distance field is constructed (i.e. a function whose value is the signed Euclidean distance to the boundary, positive interior, negative exterior) on the initial circle, the normalized gradient of this field will be the circle normal.
For various reasons, individuals are known to attribute significance to dates and numbers. One notable example is the significance given to "the eleventh hour of the eleventh day of the eleventh month," which corresponds to 11:00 a.m. (Paris time) on 11 November 1918.
A linear subspace or vector subspace W of a vector space V is a non-empty subset of V that is closed under vector addition and scalar multiplication; that is, the sum of two elements of W and the product of an element of W by a scalar belong to W. [10] This implies that every linear combination of elements of W belongs to W. A linear subspace ...
The Puget Sound region is a coastal area of the Pacific Northwest in the U.S. state of Washington, including Puget Sound, the Puget Sound lowlands, and the surrounding region roughly west of the Cascade Range and east of the Olympic Mountains. It is characterized by a complex array of saltwater bays, islands, and peninsulas carved out by ...
This chapter can be divided into two main parts, verses 1–9 and verses 11–16, with verse 10 as a connecting statement between them. [1] The New International Version entitles the chapter "The Branch from Jesse".
