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.
Interpretation
Beauty is influenced by cultural and personal factors, but mathematical beauty exists universally beyond these influences.
In this quote, Paul Dirac emphasizes that while the perception of beauty in art and literature is often shaped by cultural upbringing, the beauty found in mathematics is universal and transcends individual backgrounds. This suggests that mathematical truths possess an inherent beauty that is recognized regardless of cultural context or personal experience, highlighting the idea that some forms of beauty can be objective and timeless.
In practice
During a lecture on the relationship between art and science, one could use this quote to illustrate how different fields perceive beauty.
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.
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 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.
Nothing will make me change my principles. Even with the knife at my neck I shall still declare, up to this day, the poor have done everything; it is time for the rich to take their turn... The selfish people, the young idlers, must be made useful, whether they like it or not, and some respite be procured for the useful and respectable worker.
The separation of state and church must be complemented by the separation of state and science, that most recent, most aggressive, and most dogmatic religious institution.
If the human race develops an electronic nervous system, outside the bodies of individual people, thus giving us all one mind and one global body, this is almost precisely what has happened in the organization of cells which compose our own bodies. We have already done it. [...] If all this ends with the human race leaving no more trace of itself in the universe than a system of electronic patterns, why should that trouble us? For that is exactly what we are now!
A gift without a heart behind it is a bribe. God asks for our heart, not our gifts.
The idea that myth is the opposite of knowledge, or the opposite of truth, is simply to disallow it. It is like saying poetry is the opposite of truth.
We have triumphed in the effort to implant hope in the breasts of the millions of our people. We enter into a covenant that we shall build the society in which all South Africans, both black and white, will be able to walk tall, without any fear in their hearts, assured of their inalienable right to human dignity — a rainbow nation at peace with itself and the world.
