It's not rocket science.
Meaning
This phrase indicates that something is very simple and does not require exceptional intelligence or specialized knowledge.
Origin
The mid-20th century was a time of colossal ambition, with humanity setting its sights on the moon. "Rocket science" was not just a job; it was the cutting edge, the pinnacle of intellectual challenge, a field demanding the brightest minds and the most intricate calculations imaginable. In this era, as engineers and physicists wrestled with the cosmic equations of space travel, ordinary people began to use this monumental endeavor as a yardstick. They'd point to a mundane task and declare, with a wry smile, "It's not rocket science," underscoring its utter simplicity by contrasting it with the literally groundbreaking work of launching payloads beyond Earth's gravity. It’s a linguistic shortcut that perfectly captures the chasm between the truly complex and the refreshingly straightforward.
