In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same. The elongation of an ellipse is measured by its eccentricity , a number ranging from to .
In mathematics, the Taylor series of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. For most common functions, the function and the sum of its Taylor series are equal near this point. Taylor series are named after Brook Taylor, who introduced them in 1715. If 0 is the point where the derivatives are considered, a Taylor series is also called a Maclaurin series, after Colin Maclaurin, who made extensive use of this special case of Taylor series in the mid 1700s.
In music, an octave or perfect octave is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music," the use of which is "common in most musical systems." The interval between the first and second harmonics of the harmonic series is an octave.

The McDonnell Douglas F/A-18 Hornet is a twin-engine, supersonic, all-weather, carrier-capable, multirole combat jet, designed as both a fighter and attack aircraft. Designed by McDonnell Douglas and Northrop, the F/A-18 was derived from the latter's YF-17 in the 1970s for use by the United States Navy and Marine Corps. The Hornet is also used by the air forces of several other nations, and formerly, by the U.S. Navy's Flight Demonstration Squadron, the Blue Angels.
In calculus, Taylor's theorem gives an approximation of a k-times differentiable function around a given point by a polynomial of degree k, called the kth-order Taylor polynomial. For a smooth function, the Taylor polynomial is the truncation at the order k of the Taylor series of the function. The first-order Taylor polynomial is the linear approximation of the function, and the second-order Taylor polynomial is often referred to as the quadratic approximation. There are several versions of Taylor's theorem, some giving explicit estimates of the approximation error of the function by its Taylor polynomial.

E major is a major scale based on E, consisting of the pitches E, F♯, G♯, A, B, C♯, and D♯. Its key signature has four sharps. Its relative minor is C-sharp minor and its parallel minor is E minor. Its enharmonic equivalent, F-flat major, has eight flats, including the double-flat B, which makes it impractical to use.
SHA-2 is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.

The Battle of Jericho, as described in the Biblical Book of Joshua, was the first battle fought by the Israelites in the course of the conquest of Canaan. According to Joshua 6:1–27, the walls of Jericho fell after the Israelites marched around the city walls once a day for six days and seven times on the seventh day then blew their trumpets. Excavations at Tell es-Sultan, the biblical Jericho, have failed to substantiate this story, which has its origins in the nationalist propaganda of much later kings of Judah and their claims to the territory of the Kingdom of Israel. The lack of archaeological evidence and the composition, history and theological purposes of the Book of Joshua have led archaeologists like William G. Dever to characterise the story of the fall of Jericho as "invented out of whole cloth".

The House with a Clock in Its Walls is a 2018 American fantasy comedy film directed by Eli Roth, based on the 1973 novel of the same name by John Bellairs. It stars Jack Black, Cate Blanchett, Owen Vaccaro, Renée Elise Goldsberry, Sunny Suljic, and Kyle MacLachlan. The film follows a young boy, Lewis, who is sent to live with his uncle, Jonathan, in a creaky, old house. He soon learns it was previously inhabited by an evil warlock. Universal Pictures released the film in the United States on September 21, 2018. It was a box office success, grossing over $131 million worldwide and received mostly positive reviews from critics who largely praised the cast, but said the film did not fully live up to its potential.
