Richard Feynman. Why
A non technical client of mine one time asked me for some kind of formal verification that if we picked a certain javascript framework, that we would be able to put bar graphs on the page. I tried to explain that any framework that allows me to have javascript, html, and css on a page will allow bar graphs. And he responded &quot;how are you sure?&quot;.<p>I played this video for him as an explanation of why it was difficult to answer that question to someone who didn&#x27;t know what javascript was. The project didn&#x27;t last much longer. To be fair by the time I was willing to show him this video, I wasn&#x27;t particularly interested in keeping the engagement going.<p>He also was a neuroscientist who didn&#x27;t know who Feynman was which kind of bugged me.
