science opportunity thinking
I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. We will not become enthusiastic for the fact, the knowledge, the absolute truth of the day, but remain always uncertain … In order to make progress, one must leave the door to the unknown ajar. Richard P. Feynman

Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

science reflection desire
The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. ... If you will simply admit that maybe [Nature] does behave like this, you will find her a delightful, entrancing thing.

Nobody knows how it can be like that.

If you thought that science was certain - well, that is just an error on your part.
science camels world
Cheetah genes cooperate with cheetah genes but not with camel genes, and vice versa.

A man or a race either if he's any good can survive his past without even needing to escape from it and not because of the high quite often only too rhetorical rhetoric of humanity but for the simple indubitable practical reason of his future: that capacity to survive and absorb and endure and still be steadfast. William Faulkner

past odds israel
We have been through, over these years, some difficult times. During the period that I have served as President of the United States, we have been through some difficult times together, and I can only say that the friendship that we have for this nation, the respect and the admiration we have for the people of this nation, their courage, their tenacity, their firmness in the face of very great odds, is one that makes us proud to stand with Israel, as we have in the past in times of trouble, and now to work with Israel in a better time, a time that we trust will be a time of peace.

expression mirrors worry
Annabeth recognized something else in her face, too - in the hard set of her mouth and the deliberate way she raised her chin like she was ready to accept any challenge.

She saw it every time she looked in a mirror. Rick Riordan
