means A systematic way of studying the world by observing, testing, and revising ideas until they survive attempts to break them.

from From Latin scientia, 'knowledge,' built on the verb scire, 'to know.' It entered English via Old French science around the 14th century, originally meaning knowledge in general — you could have 'science' of cooking or sin. Only from roughly the 17th century onward, as experimental method took hold, did the word narrow toward its modern sense: knowledge earned specifically through observation and testing, not just learned or asserted.
