Awarding B.S. Degrees

Though I have all the respect in the world for them, I really wonder why some professionals are awarded B.S. degrees.  The "S" is supposed to be for science, isnt' it?

Engineers.  Archaelogists.  Architects.

These are the science people that I often hire to work on various projects. 

I see engineers design roads and then the infamous "proof roll" is used to determine the road is done right.  That exercise is two guys walking behind a heavily laden truck and seeing if they think the road is done right.  This is science?

Archaelogists start digging in the dirt and looking at shades of dirt.  They always seem to reach the same conclusion.  We didn't find it today, but that doesn't mean it isn't there.  Yeah, right.  Science?

Architects give you plans for a building and then scratch their heads when the builder can't figure out how to get air flow through a duct that is designed to go through a steel beam.  Yep.  Science.

Sure, B.S. degrees.  Right.
