It's not so much what Hank Green said, but what the Hank Green-hosted SciShow on YouTube put forward. The video is framed as physicists using science to explain the art of knitting, which until now has been innovated simply "through trial and error," and that "how it all works was mostly a mystery." Recently, scientists used a computer model to determine how certain knit stitches will behave, thus being able to predictively pattern knit fabrics for the first time.
The method has been tremendously successful for science, as we've discovered what makes up the Universe, in what proportion, and what the force laws are that govern physical scales ranging from the subatomic to the cosmological.
