A Quote by Kenneth Arrow
Evolutionary theory tends to explain quite well in retrospect how various species emerged. It's not very good on prediction. Nevertheless, one cannot say that there isn't a lot of knowledge that's been obtained in this field. In the same way, with these complex physical phenomena between solid state physics, you can say a lot of things without necessarily knowing the next step.

When I was in college, I didn't like physics a lot, and I really wasn't very good at physics. And there were a lot of people around me who were really good at physics: I mean, scary good at physics. And they weren't much help to me, because I would say, 'How do you do this?' They'd say, 'Well, the answer's obvious.'
Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.
What would it mean if there were a theory that explained everything? And just what does "everything" actually mean, anyway? Would this new theory in physics explain, say the meaning of human poetry? Or how economics work? Or the stages of psychosexual development? Can this new physics explain the currents of ecosystems, or the dynamics of history, or why human wars are so terribly common?
You can't say, 'You're a scorer, you score. You rebound, you rebound.' Basketball is more than that. Basketball is knowing the next step, knowing the next play, knowing how to make things happen.
Wisdom and knowledge can best be understood together. Knowledge is learning, the power of the mind to understand and describe the universe. Wisdom is knowing how to apply knowledge and how not to apply it. Knowledge is knowing what to say; wisdom is knowing whether or not to say it. Knowledge gives answers; wisdom asks questions. Knowledge can be taught, wisdom grows from experience.
We are so far from knowing all the forces of nature and their various modes of action that it would be unworthy of the philosopher to deny phenomena simply because they are inexplicable at the present state of our knowledge. The more difficult it is to acknowledge their existence, the greater the care with which we must study these phenomena.
Of true knowledge at any time, a good part is merely convenient, necessary indeed to the worker, but not to an understanding of his subject: One can judge a building without knowing where to buy the bricks; one can understand a violin sonata without knowing how to score for the instrument. The work may in fact be better understood without a knowledge of the details of its manufacture, of attention to these tends to distract from meaning and effect.
We should think about what we mean by literacy. If you say, "He's a very literate person," what you really mean is that he knows a lot, thinks a lot, has a certain frame of mind that comes through reading and knowing about various subjects.The major route open to literacy has been through reading and writing text. But we're seeing new media offer richer ways to explore knowledge and communicate, through sound and pictures.
It can be very lonely knowing that you have things to say but you daren't say them. Knowing that you could contribute to something but you don't dare quite do it.
We often say that our science is objective and accurate, but we don't often say that our science is incomplete - that although the established parts of natural science are very well tested and the evidence makes a compelling case for things being as they've been described, there nevertheless are open questions that we cannot answer.
The actual communicative value of what we say is usually quite small. I've lived for times in small, isolated fishing villages, where everyone knows everyone each other and everyone knows what's going on and everyone's watched the same TV programs and, really, there's not a whole lot of new information to convey. But there's still a lot of talking. What's said doesn't seem to matter; that you say it, and who you say it to, and how you say it is what matters.
Being tall when I was youngerl I was always a bit awkward. As a teenager, I was very, very thin, so I was very gangly and limby, and would sweep things off the table without realising how big my wingspan was - just out of control. A lot of women write to me and say, 'I'm six foot and exactly the same happens' - that's been lovely therapy.
One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.
The first step to the knowledge of the wonder and mystery of life is the recognition of the monstrous nature of the earthly human realm as well as its glory, the realization that this is just how it is and that it cannot and will not be changed. Those who think they know how the universe could have been had they created it, without pain, without sorrow, without time, without death, are unfit for illumination.
I would say my career is in a very good place. I'm in a place of a lot of hope for what's next. I see something great, but I'm not quite there.
The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory , you must try to explain what's good and what's bad about it equally. In science, you learn a kind of standard integrity and honesty .
