Erdos liked to quote a colleague's remark that "A mathematician is a machine
for converting coffee into theorems"

Now, who was this "colleague" ?
Was it Renyi, as I read once in a sci.math posting (but without references)?
(*) What exactly is mathematics? Many have tried but nobody has really
succeeded in defining mathematics; it is always something else.
