    The 18 one-sided pentominoes, including 6 mirrored pairs.. A polyomino is a plane geometric figure formed by joining one or more equal squares edge to edge. It is a polyform whose cells are squares.

  6. Science - Wikipedia

    en.wikipedia.org/wiki/Science

    Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. [1] [2] Modern science is typically divided into two or three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the behavioural sciences (e.g., economics, psychology, and sociology ...

    en.wikipedia.org/wiki/Scientific_method

    The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...

    For example, x 2 = 40x − 4x 2 is reduced to 5x 2 = 40x. Al-muqābala is the process of bringing quantities of the same type to the same side of the equation. For example, x 2 + 14 = x + 5 is reduced to x 2 + 9 = x. The above discussion uses modern mathematical notation for the types of problems that the book discusses.
