The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
Paul DiracRead
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.
Interpretation
The pursuit of mathematical beauty should take priority over simplicity in scientific research.
In this quote, Paul Dirac emphasizes the importance of aesthetic appeal in mathematical expressions of natural laws, suggesting that while simplicity is valuable, it should yield to beauty when the two are in conflict. This highlights a philosophical approach to science where the elegance of formulations is considered a guiding principle in understanding the complexities of nature.
In practice
In a lecture about scientific theories, to illustrate the importance of beauty in mathematics.
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe.
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
It is quite clear that beauty does depend on one's culture and upbringing for certain kinds of beauty, pictures, literature, poetry and so on...But mathematical beauty is of a rather different kind. I should say perhaps it is of a completely different kind and transcends these personal factors. It is the same in all countries and at all periods of time.
It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress.
There is in my opinion a great similarity between the problems provided by the mysterious behavior of the atom and those provided by the present economic paradoxes confronting the world.
The cyclic universe theory predicts no gravitational waves from the early universe.
The roads by which men arrive at their insights into celestial matters seem to me almost as worthy of wonder as those matters in themselves.
At the core of 'Star Trek' is Gene Roddenberry's vision of the future. So much of science-fiction is about a dystopian society with human civilization having crumbled. He had an affirmative, shining, positive view of the future.
My roots, in college, were in behavior in the context of evolution.
When a physician is called to a patient, he should decide on the diagnosis, then the prognosis, and then the treatment. ... Physicians must know the evolution of the disease, its duration and gravity in order to predict its course and outcome. Here statistics intervene to guide physicians, by teaching them the proportion of mortal cases, and if observation has also shown that the successful and unsuccessful cases can be recognized by certain signs, then the prognosis is more certain.
In physics, your solution should convince a reasonable person. In math, you have to convince a person who's trying to make trouble. Ultimately, in physics, you're hoping to convince Nature. And I've found Nature to be pretty reasonable.
