One of my students in Linear Algebra reminded me of quote I had heard some time back concerning the pecking order of the sciences. The version he quoted was what he had heard from a colleague of mine here at Wayland:
All chemists want to be physicists.
All physicists want to be mathematicians.
Although, I couldn’t recall it at the time. I looked it up and found the two forms of this quote I have heard before:
Biologists answer only to Chemists.
Chemists answer only to Physicists.
Physicists answer only to Mathematicians.
Mathematicians answer only to God.
or
The biologist wants to be a chemist.
The chemist wants to be a physicist.
The physicist wants to be God.
God wants to be a mathematician.
No, I do not have a God complex. But who could blame me. I am a mathematician.

I like th middle one the best, the one that says “Mathematicians answer only to God”

By the way, the student in class was a she, not a he.

I guess I was reminded by a couple of folks. Sorry for that.
