Fun facts, FFT was discovered back in 1965 based on the urgent necessity of discovering and detecting illegal nuke testing activities, just two years after the Partial Test Ban Treaty (PTBT) was signed in 1963 [1].
The first sentence statement in the article mentioning that United States and other nuclear powers committed to the Comprehensive Nuclear-Test-Ban Treaty in 1965 is wrong since the treaty was only signed in 1996 not in 1965 [2].
