Science in a wide sense means systematic gathering, inference and organization of knowledge, in a more strict sense this process has to be kept rational by obeying some specific strict rules and adhering to objective principles such as the [scientific method](scientific_method.md) or mathematical [proof](proof.md). Sciences in the strict sense include [mathematics](math.md) (so called formal science), [physics](physics.md), biology, chemistry, [computer science](computer_science.md) etc. Science is not to be confused with [pseudoscience](pseudoscience.md) (such as gender studies or astrology) and [soyence](soyence.md) (political propaganda masked as "science").
