There is nearly always more than one solution ... the sort of situation engineers and scientists hate but artists love.

This is the kind of ignorant claptrap I have encountered all too often during my professional career, usually from people who have little idea what is involved in Science or Engineering.

Good engineering design involves identifying a range of solutions to a problem, then homing in on the most appropriate solution for the particular circumstance. For that reason, contrary to your belief, engineers are not uncomfortable with multiple solutions.

Sorry about the thread drift, but comments like the one above have always annoyed me.
