Professor of Chemistry Office: E302-A Central Park Campus 972-548-6512 ael-ashmawy@collin.edu "I feel sorry for people who don't understand anything about chemistry.  They are missing an important source of happiness." -- Linus Pauling (1901-1994) "Beginning students in chemistry often think of the science as a mere collection of disconnected data to be memorized by brute force. Not at all!! Just look at it properly and everything hangs together and makes sense." -- Isaac Asimov (1920-1992)
