You have to be careful when you use beauty as a guide. There are many theories people didn't think were beautiful at the time but did find beautiful later?and vice versa. I think simplicity is a good guide: The more economical a theory, the better.
If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.
The most reliable appliance has simplicity and quality, does what is demanded of it, is economical to use, easy to maintain, and just as easy to repair. ...It also sells best and looks good.
The art of art, the glory of expression, is simplicity. Nothing is better than simplicity, and the sunlight of letters is simplicity. Nothing is better than simplicity-nothing can make up for excess, or for the lack of definiteness.
A theory is the more impressive the greater is the simplicity of its premises, the more different are the kinds of things it relates and the more extended the range of its applicability.
A theory is the more impressive the greater the simplicity of its premises is, the more different kinds of things it relates, and the more extended its area of applicability.
A theory is the more impressive the greater the simplicity of its premises is, the more different kinds of things it relates, and the more extended is its area of applicability. Therefore the deep impression which classical thermodynamics made upon me. It is the only physical theory of universal content concerning which I am convinced that within the framework of the applicability of its basic concepts, it will never be overthrown.
There's an economy in sports that I always think is a useful metaphor for acting. You have an objective. You're trying to win, and of course, you want to do well. You want to use good techniques so you enforce it, but also you don't do things you don't have to do. It's very economical, and I think that in acting the most economical way through a scene is always the best. It's active. There is the sense of the fight and you want to win.
A good guide will take you through the more important streets more often than he takes you down side streets; a bad guide will do the opposite. In philosophy I'm a rather bad guide.
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
I think having simplicity doesn't always mean that you make a good movie. I have a theory that a movie that's easy to make is hard to watch.
What is especially striking and remarkable is that in fundamental physics, a beautiful or elegant theory is more likely to be right than a theory that is inelegant. A theory appears to be beautiful or elegant (or simple, if you prefer) when it can be expressed concisely in terms of mathematics we already have. Symmetry exhibits the simplicity. The Foundamental Law is such that the different skins of the onion resemble one another and therefore the math for one skin allows you to express beautifully and simply the phenomenon of the next skin.
A hypothetical theory is necessary, as a preliminary step, to reduce the expression of the phenomena to simplicity and order before it is possible to make any progress in framing an abstractive theory.
Einstein has a feeling for the central order of things. He can detect it in the simplicity of natural laws. We may take it that he felt this simplicity very strongly and directly during his discovery of the theory of relativity. Admittedly, this is a far cry from the contents of religion. I don't believe Einstein is tied to any religious tradition, and I rather think the idea of a personal God is entirely foreign to him.
Beauty of style and harmony and grace and good rhythm depend on simplicity - I mean the true simplicity of a rightly and nobly ordered mind and character, not that other simplicity which is only a euphemism for folly.
Some people seem to think that my life dedicated to simplicity and service is austere and joyless, but they do not know the freedom of simplicity. I am thankful to God every moment of my life for the great riches that have been showered upon me. My life is full and good but never overcrowded. If life is overcrowded then you are doing more than is required for you to do.
