Rocket science意思

"Rocket science" is a term that is often used metaphorically to refer to something that is extremely complex or difficult to understand, especially in the fields of science and engineering. The phrase suggests that the subject matter is as complicated as the science behind spaceflight and rocket propulsion, which is indeed a highly technical and specialized field.

However, it's important to note that when used in this way, "rocket science" does not necessarily imply that the subject is inherently more complex than other fields of study. Instead, it serves as a colorful way to emphasize the complexity or difficulty of a particular topic. The term has become part of popular culture and is often used in a casual or even slightly humorous manner.
