A B.S. in physics means that you know a little bit about all of physics but nothing very well.
A wise man doesn't stop learning once he stops attending classes. You shouldn't make assumptions about strangers, they give away your ideals.
No a wise man doesn't (and since I am working on my graduate degree now that 'ideal' you hint at me having has not yet taken root). However most people do. And trusting in something with a complicated name that YOU don't understand because someone says they got a B.S. in physics is a sure way to get burned (as proven today). Especially when a physics degree does not directly prepare you for that complicated thing.
