A Quote by Steven Weinberg

I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.
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.
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.
You may object that by speaking of simplicity and beauty I am introducing aesthetic criteria of truth, and I frankly admit that I am strongly attracted by the simplicity and beauty of mathematical schemes which nature presents us. You must have felt this too: the almost frightening simplicity and wholeness of the relationship, which nature suddenly spreads out before us.
The research worker, in his efforts to express the fundamental laws of Nature in mathematical form, should strive mainly for mathematical beauty. He should take simplicity into consideration in a subordinate way to beauty ... It often happens that the requirements of simplicity and beauty are the same, but where they clash, the latter must take precedence.
Simplicity. Simplicity. Simplicity. The three keys to a spiritual life.
I think there is a profound and enduring beauty in simplicity; in clarity, in efficiency. True simplicity is derived from so much more than just the absence of clutter and ornamentation. It's about bringing order to complexity.
In spite of the fact that religion looks backward to revealed truth while science looks forward to new vistas and discoveries, both activities produce a sense of awe and a curious mixture of humility and arrogance in their practitioners. All great scientists are inspired by the subtlety and beauty of the natural world that they are seeking to understand. Each new subatomic particle, every unexpected object, produces delight and wonderment. In constructing their theories, physicists are frequently guided by arcane concepts of elegance in the belief that the universe is intrinsically beautiful.
I mean just look at haiku, the idea of it. We want to focus on that singularity, on that simplicity, but we still want to add features and add value, but we want to do it in a way that fits in with that mentality of simplicity. You have to spend a lot of time thinking about it.
Capablanca's play produced and still produces an irresistable artistic effect. In his games a tendency towards simplicity predominated, and in this simplicity there was a unique beauty of genuine depth.
The thing about simplicity is it's not easy to achieve. To many, simplicity can mean repetitiveness and maybe even a lack of intelligence, those kind of things, but simple yet unique is the key.
By walking naked you gain far more than coolness. You feel an unexpected sense of freedom from restraint. An uplifting and almost delirious sense of simplicity. In this new simplicity you soon find that you have become, in a new and surer sense, and integral part of the simple, complex world you are walking through. And then you are really walking.
Simplicity, simplicity, simplicity! I say, let your affairs be as two or three, and not a hundred or a thousand; instead of a million count half a dozen, and keep your accounts on your thumb nail.
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.
The simplicity of the universe is very different from the simplicity of a machine. The simplicity of nature is not that which may be easily read but is inexhaustible. The last analysis can no wise be made.
If you look at the last 150 years, about every 30 years or so, a new scientific discipline emerges that starts spinning out technologies and capturing people's imaginations. Go back to 1900: That industry was chemistry. People had chemistry sets. In the 1930s, it was the rise of physics and physicists. They build on each other. Chemists laid the experimental understanding for the physicists to build their theories. It was three physicists who invented the transistor in 1947. That started the information revolution. Today, kids get computers.
Simplicity is the final achievement. After one has played a vast quantity of notes and more notes, it is simplicity that emerges as the crowning reward of art.
