I think it is a peculiarity of myself that I like to play about with equations, just looking for beautiful mathematical relations which maybe don't have any physical meaning at all. Sometimes they do._x000D_ _x000D_ At age 60.
Interpretation
The quote expresses a fascination with finding beauty in mathematical equations, regardless of their practical applications.
Paul Dirac shares his unique trait of enjoying the exploration of mathematical equations for their aesthetic appeal. He suggests that while some mathematical relations may not manifest any physical significance, they still hold an intrinsic beauty that can be appreciated on its own. This reflects a deeper philosophical perspective on the nature of mathematics and its relation to the real world.
In practice
During a lecture on abstract math, a professor might use this quote to emphasize the beauty in theoretical equations.
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 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.
I am not accustomed to saying anything with certainty after only one or two observations.
Evolution is a fact. It is the best explanation of what is known from observations. It's a theory as powerful as the theory of gravity.
When I left NASA, I was looking at how you could use space technologies for developing countries' work.
Given the power and influence that science increasingly has in our daily lives, it is important that we as citizens of an open and democratic society learn to separate good science from bunk. This is not just a matter of intellectual curiosity, as it affects where large portions of our tax money go, and in some cases even whether people’s lives are lost as a result of nonsense.
You can prove anything you want by coldly logical reason---if you pick the proper postulates.
It is always noteworthy that all those who seriously study this science [the theory of numbers] conceive a sort of passion for it.
