The best that Gauss has given us was likewise an exclusive production. If he had not created his geometry of surfaces, which served Riemann as a basis, it is scarcely conceivable that anyone else would have discovered it. I do not hesitate to confess that to a certain extent a similar pleasure may be found by absorbing ourselves in questions of pure geometry.
The subject of the poem usually dictates the rhythm or the rhyme and its form. Sometimes, when you finish the poem and you think the poem is finished, the poem says, "You're not finished with me yet," and you have to go back and revise, and you may have another poem altogether.

There may have been disillusionments in the lives of the medieval saints, but they would scarcely have been better pleased if they could have foreseen that their names would be associated nowadays chiefly with racehorses and the cheaper clarets.
It may also be pertinent to ask whether a greater effort in the less expensive basic stages of research may not lead to reductions of effort in the far costlier stages of development and prototype construction.
