[BBC Space Documentary 2015 HD] Weirdest Planets: New Science Documentary Full Length++ Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that
builds and organizes knowledge in the form of testable explanations and predictions about
the universe.[nb 1] In an older and closely related meaning, "science" also refers to this
body of knowledge itself, of the type that can be rationally explained and reliably
applied. Ever since classical antiquity, science as a type of knowledge has been closely
linked to philosophy. In the West during the early modern period the words "science"
and "philosophy of nature" were sometimes used interchangeably,:p.3 and until the
19th century natural philosophy (which is today called "natural science") was considered
a branch of philosophy.

In modern usage however, "science" most often refers to a way of pursuing knowledge,
not only the knowledge itself. It is also often restricted to those branches of study
that seek to explain the phenomena of the material universe. In the 17th and 18th
centuries scientists increasingly sought to formulate knowledge in terms of laws of
nature. Over the course of the 19th century, the word "science" became increasingly
associated with the scientific method itself, as a disciplined way to study the natural
world, including physics, chemistry, geology and biology. It is in the 19th century also
that the term scientist began to be applied to those who sought knowledge and understanding
of nature. However, "science" has also continued to be used in a broad sense to denote
reliable and teachable knowledge about a topic, as reflected in modern terms like library
science or computer science. This is also reflected in the names of some areas of academic
study such as social science and political science
