English Idioms About “Science”
Idiom: Spuntnick moment
Meaning: The phrase Sputnik moment refers to a moment of challenge when a society or person realizes they must work harder to surpass their competitors. The phrase was popularized by Barack Obama in his State of the Union address in 2011. The origin of the idiom comes from the Soviet Union’s 1957 launch of the first Earth-orbiting satellite Sputnik 1, which was a great achievement at that moment, while the US were lagging behind in space technology. This caused the space race to start between the two countries. The US ultimately won the race in 1969 with the first human landing on the Moon.
Example: This generation’s “Sputnik moment” has arrived, President Barack Obama declared in his State of the Union address, referring to the United States’ need to invest in research and development to revive the economy and ensure future stability.
