I love Feynman he was an entertainer, but honestly, even CalTech admitted that nobody really advanced in understanding or created anything out his works, its all like intellectual mind candy.

People who understand things who can roll up their sleeves, and get the job done, are a rare breed, this stuff can't be taught.

Later, after you create you can return to Feynman, have a cold-beer, and listen to his lectures and have a good laugh.
