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.
Soon comes the cold, and the night that never ends.
When we are planning for posterity, we ought to remember that virtue is not hereditary.
There was not a single Negro slave owner who did not know dozens of Negroes just as capable of learning and efficiency as the mass of poor white people around and about, and some quite as capable as the average slaveholder. They had continually, in the course of the history of slavery, recognized such men.
I built my soul a lordly pleasure-house, Wherein at ease for aye to dwell.
Why do we cling to bigotry? Because bigotry, plainly, is convenient. It is a near-effortless way to both elevate one's stature and make a pity grab in this culture of victims that we have become.
Someone accompanies every soul from the other side when it enters this place. Usually it is an ancestor with whom that child shares traits and gifts
