Optimally Quotes (2 quotes)
Engineers participate in the activities which make the resources of nature available in a form beneficial to man and provide systems which will perform optimally and economically.
1957
Our world is not an optimal place, fine tuned by omnipotent forces of selection. It is a quirky mass of imperfections, working well enough (often admirably); a jury-rigged set of adaptations built of curious parts made available by past histories in different contexts ...

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again.

I cannot recall the last time something like that happened in politics or religion.
(1987) --
