Optimist Quotes (8 quotes)
A pessimist is a person who is always right but doesn’t get any enjoyment out of it, while an optimist, is one who imagines that the future is uncertain. It is a duty to be an optimist, because if you imagine that the future is uncertain, then you must do something about it.

If there’s one thing in physics I feel more responsible for than any other, it’s this perception of how everything fits together. I like to think of myself as having a sense of judgment. I’m willing to go anywhere, talk to anybody, ask any question that will make headway. I confess to being an optimist about things, especially about someday being able to understand how things are put together. So many young people are forced to specialize in one line or another that a young person can’t afford to try and cover this waterfront — only an old fogy who can afford to make a fool of himself. If I don't, who will?

Men will gather knowledge no matter what the consequences. Science will go on whether we are pessimistic or optimistic, as I am. More interesting discoveries than we can imagine will be made, and I am awaiting them, full of curiosity and enthusiasm.

RAILROAD, n. The chief of many mechanical devices enabling us to get away from where we are to where we are no better off. For this purpose the railroad is held in highest favor by the optimist, for it permits him to make the transit with great expedition.

There are in this world optimists who feel that any symbol that starts off with an integral sign must necessarily denote something that will have every property that they should like an integral to possess.

In 'Integrals Devised for Special Purposes', Bulletin of the American Mathematical Society (1963), 69, 611.
To the optimist, the glass is half full. To the pessimist, the glass is half empty. To the engineer, the glass is twice as big as it needs to be.
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. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
