As the child delights in his mud pie, so the adult enjoys building things, especially things of his own design. Second is the pleasure of making things that are useful to other people. Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts and watching them work in subtle cycles, playing out the consequences of principles built in from the beginning. Fourth is the joy of always learning, which springs from the（ 2 ）nature of the task. In one way or another the problem is ever new, and its solver learns something: sometimes（ 3 ）, sometimes theoretical, and sometimes both. Finally, there is the delight of working in such a tractable medium. The（ 4 ）, like the poet, works only slightly removed from pure thought-stuff.
