"Design is what you do
when you don't [yet] know what you are doing.''
"Engineering problems are under-defined, there are many solutions, good, bad and indifferent. The art is to arrive at a good solution. This is a creative activity, involving imagination, intuition and deliberate choice."
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible.”
