It usually takes about fifty years for a fruitful idea to penetrate a scientific discipline. The magnetic moment of hydrogen was discovered in 1941; half a century later hundreds of scientists were using fMRI scanners, which rely on this fact, to measure the brain.

I guess the guy does not consider physics a scientific discipline :(
Magnetic moment has penetrated it the moment it was discovered

J.K. is not trying to generalize here. He talks about a discovery in one scientific discipline ( physics) that, after being embodied in a practical tool, penetrates another scientific discipline (experimental psychology). This interpepretation is fairly clear in the book's context.
