资料题：Valentine's Day is on every year（　）。

Science is sometimes confused with technology, which is the application of science to various tasks.Such confusion is often aided by some school texts that have pictures of rockets on the moon and are titled with"Science Marches on!".The technology that makes rocket landing onthe moon possible emerged from the use of scientific strategies in the study of propulsion, electronics, and numerous other fields.It is the way of inquiry that is scientific; the rocket is a piece of technology.Just as science is not technology, neither is specific body of knowledge.The popular phrase"Science tells us smoking is bad for your health"really misleads."Science"doesn't tell us anything; people tell us things, in this case people who have used scientific strategies to investigate the relationship of smoking to health tell us things.Science may be best regarded as existing not in books, or in machinery, or in reports containing numbers, but rather in that invisible world of the mind.Science has to do with the way questions are formed and answered; it is a set of rules and forms of inquiry created by people who want reliable answers.
