Pell's equation, also called the Pell–Fermat equation, is any Diophantine equation of the form where n is a given positive nonsquare integer and integer solutions are sought for x and y. In Cartesian coordinates, the equation is represented by a hyperbola; solutions occur wherever the curve passes through a point whose x and y coordinates are both integers, such as the trivial solution with x = 1 and y = 0. Joseph Louis Lagrange proved that, as long as n is not a perfect square, Pell's equation has infinitely many distinct integer solutions. These solutions may be used to accurately approximate the square root of n by rational numbers of the form x/y.
Thomas Hobbes was an English philosopher, considered to be one of the founders of modern political philosophy. Hobbes is best known for his 1651 book Leviathan, in which he expounds an influential formulation of social contract theory. In addition to political philosophy, Hobbes contributed to a diverse array of other fields, including history, jurisprudence, geometry, the physics of gases, theology, and ethics, as well as philosophy in general.

Grammatophyllum, sometimes abbreviated in horticultural trade as Gram, is a genus of 13 currently known orchid species. The name is derived from the Greek words 'gramma' and 'phyllon' (leaf), referring to the parallel leaf veins or the markings of the perianth. This epiphytic genus occurs in dense rainforest from Indo-China, to Indonesia, the Philippines, New Guinea, and the Southwest Pacific islands.
Grammatophyllum speciosum, also called giant orchid, tiger orchid, sugar cane orchid or queen of the orchids, is a species of orchid native to Indonesia. It is listed by the Guinness Book of World Records as the world's tallest orchid, with specimens recorded up to 7.62 metres (25 ft) in height.

The Hobbes–Wallis controversy was a polemic debate that continued from the mid-1650s well into the 1670s, between the philosopher Thomas Hobbes and the mathematician John Wallis. It was sparked by De corpore, a philosophical work by Hobbes in the general area of physics. The book contained not only a theory of mathematics subordinating it to geometry and geometry to kinematics, but a claimed proof of the squaring of the circle by Hobbes. While Hobbes retracted this particular proof, he returned to the topic with other attempted proofs. A pamphleteering exchange continued for decades. It drew in the newly formed Royal Society, and its experimental philosophy to which Hobbes was opposed.
