Mathematics and Art

Thursday, May 14th, 2009

A mathematician, like a painter or a poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas. I am interested in mathematics only as a creative art – Godfrey Harold Hardy

Recently a friend who is theoretical computer scientist was commenting to another friend (who has a degree in arts and design) about how much mathematics has in common with arts and design. He explained how some one doing mathematics creatively tries to find intricate and useful structure which may help in problem solving. He stressed how a creative combination of small ideas leads to the ‘final piece of art’. I was amused when our artistic friend gave an incredulous look. This is a common reaction. It can be frustrating to explain to others that mathematical activity is creative in its essence and not mechanical like arithmetic.

Perhaps, Sir Michael Atiyah does of a better job at explaining at least one aspect of this issue:

The art in good mathematics, and mathematics is an art, is to identify and tackle problems that are both interesting and solvable. Proof is the end product of a long interaction between creative imagination and critical reasoning. Without proof the program remains incomplete, but without the imaginative input it never gets started.

One can see here an analogy with the work of the creative artist in other fields: writer, painter, composer, or architect. The vision comes first, it develops into an idea that gets tentatively sketched out, and finally comes the long technical process of erecting the work of art. But the technique and the vision have to remain in touch, each modifying the other according to its own rules.

Elementary versus Easy

Tuesday, May 12th, 2009

Peter Sarnak is a well known mathematician who is also a permanent member of the Institute for Advanced Study. In the ‘Final Perspectives’ of The Princeton Companion to Mathematics, Sarnak makes some useful comments on the nature of good scholarship. One of the points he discusses is the difference between elementary versus easy. Whereas easy results are obviously not valued because of their lack of novelty, using elementary tools or arguments to present interesting ideas should not take away anything from the ideas. It is desirable to present ideas or proofs (in the case of mathematics) in an efficient, elegant and simple manner as possible. In fact in mathematics, ‘proofs from the book’ are exactly those proofs which appear the most natural and elegant for the particular theorem. Sarnak particularly stresses the point that using fancy notation does not imply deep work:

There is a tendency among some young mathematicians to think that using fancy and sophisticated language means that what they are doing is deep. Nevertheless, modern tools are powerful when they are understood properly and when they are combined with new ideas. Those working in certain fields (number theory, for example) who do not put in the time and substantial effort needed to learn these tools are putting themselves at a great disadvantage. Not to learn the tools is like trying to demolish a building with just a chisel. Even if you are very adept at using the chisel, somebody with a bulldozer will have a huge advantage and will not need to be nearly as skilful as you.

This point is further highlighted by great papers. Authors of great papers worked extra hard to simplify the arguments and make the paper more readable and presentable.

Gordon Brown and science

Tuesday, March 17th, 2009

The economics recession has been having an effect in every area. However, Prime Minister Gordon Brown pledged that UK research will not be a victim of the recession. He said that the recession is an opportunity to change the focus from financial services to foundational scientific research, high technology and high-value engineering. (more…)

Two Game Theorists

I recently wrote a short note for the university economics society publication. It consisted of brief profiles on two game theorists who passed away in 2008. The following is taken from the note: (more…)
