Carver Mead on engineering:
Engineering isn’t something you study and learny, and memorize, and know where to look up. Engineering is understanding things all the way to the bottom, no matter what field they are called, and being able use that to build stuff and make it work.
I edited the quote slightly. Mead was speaking in the past tense about the attitude that Royal Sorensen brought to Cal Tech. I thought the stand-alone quote would be easier to read in the present tense.
