The strange quest: Mathematics as Concrete Art

October 10, 2009

I have to confess that this post has not been an easy one to write. I wanted to express some ideas that are difficult to put into words. The central, rather playful, thesis is that pure mathematics itself is a branch of concrete art.

Let me begin with some easy facts. This month, I have had the great fortune to be able to take part in a studio exhibition with a group of constructive/concrete artists, including members of the systems group from the 1960′s.  The exhibition was curated by Trevor Clarke in Peter Lowe’s studio.  As a result I have had a chance to have some fascinating conversations with several artists, including Peter Lowe, Trevor Clarke and Jeffrey Steele.

One goal of the exhibition is to start dialogues between artists and technicians, in the spirit of the studio exhibitions that started the systems group in the 1950′s around Adrian Heath and Kenneth and Mary Martin.  With that in mind I would like to give some of the ideas that emerged for me from the conversations.

Constructive and Concrete art arose from a natural conclusion of the process of abstraction. In the case of concrete art this is explicit and stated in Van Doesberg’s “Manifesto of Concrete Art”. Abstraction began by cutting away the figurative and symbolic content of artworks. As this program progresses more and more is cut away until, in a natural conclusion, one is left with nothing. Nothing is a fascinating concept. It is certainly not a trivial one, as we see with relatively late arrival of zero as a number. It does not, however, give a large space in which ideas can work. An empty canvas is an empty canvas and one ends up unable to tell the profound from the lazy. Concrete art emerges from this vacuum as the attempt to produce artworks that are not empty but have no figurative or symbolic meaning. It seems that this goal can be achieved in two distinct ways. One can either take the subconscious or irrational approach that leads to mysticism or the hyper-rational approach to create small works with their own logic.  For obvious reasons I want to consider the second here.

This would seem to argue for a very subjective art, as we must not only consider different personal opinions about a piece, but the individual world that each piece inhabits. Constructivism is more ambitious than this. The idea of removing figure and symbol is not nihilism, but a desire to address raw or objective beauty. It is of course fully accepted that no such beauty exists. This leads to a strange quest, where the goal is known to be unobtainable.

I come into this from a different point of view. My art does not contain mathematics in order to have no content, but to communicate mathematics. The mathematics is precisely the symbolic meaning. Yet what is mathematics? My personal definition is that mathematics is any concept that can be considered without reference to the real world. I know that this is an intellectual land grab, but I favour overlapping disciplines anyway. Putting this definition together with the constructivist quest for beauty led to some interesting similarities. Let us consider a parallel history of the two topics.

In the late nineteenth century, while painting was starting the move to abstraction with the work of impressionists and others, mathematics was starting a re-examination of its axiomatic roots. Just as art became more abstract the concepts and fields of mathematics were being cut back to rest on top of the set theory of Cantor and Dedekind.  By the 1930′s the impossibilities inherent in both quests were becoming apparent. A year after Van Doesberg published the “Manifesto of Concrete Art”, Göodel published “On formally undecidable propositions of Principia Mathematica and related systems”.  This work showed that whatever axioms one considered (that allow arithmetic) there would always be holes, statements that the axioms did not say were true or false, and one could never be sure that there was not a contradiction a statement both true and false. This was the end of the dream of a perfect mathematical machine. Pure mathematics thus joined in the strange quest, seeking patterns and structure without the possibility of obtaining a final goal.

In fact by the 1940′s the two subjects were recognising their similarities. Hardy published “A mathematician’s Apology” in 1940 that claimed that mathematics was an art form. With the humility that only a Cambridge academic can feel for his own place in the world he declared:

“A mathematician, like a painter or poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.”

The quest of a mathematician, to Hardy, was to find beauty and truth, yet without defining exactly what he meant by either. This bears a striking similarity to the vision of constructivism that I described above.  It is no surprise therefore that, perhaps unaware that mathematics had been declared an art, in 1949 Max Bill considered “The Mathematical Approach in Contemporary Art”.

I want to reverse Bill and consider that perhaps the mathematical structure itself, from gauge theory to groups, from motives to matrices from the games of Conway to the technical depth of Grothendieck, stopping on the way to take in the Hopf fibration and bifurcation, the Penrose tiling, and the 57-cell, is simply one giant work of concrete art put together by a cast of thousands.  An edifice built with some logical consistency on the Zermelo-Frankael axioms and the fudge factor axiom of choice.

So here’s to everyone pursuing the strange quest in the belief that the universe has an inexhaustible supply of secrets, and there will always be new beauty to be found even in some of its simplest corners.

Responsibility of Mathematicians

December 9, 2008

This week, my apologies, the post is a little late.  However I have an excuse!  I wanted to put the piece below out, but wanted to make sure that it had been published (in the December issue of Mathematics Today, the magazine of the Institute for Mathematics and its Applications/IMA) first.  So apologies again and enjoy…

The world’s financial markets are in trouble, leading the whole world into crisis.  The causes will probably remain murky; economists still debate what caused the Great Depression.  However it cannot be disputed that complicated mathematics has become an increasing part of the business of large financial institutions.  Furthermore the models produced by this mathematics are often used primarily for profit rather than understanding.  Maybe we can no longer hide behind G.H. Hardy’s claim that:

it would be paradoxical to suggest that mathematics of any sort does much harm in a time of peace. 

A Mathematician’s Apology

  The use of mathematics for financial modelling is a modern application that is now widely accepted.  However many other new areas are opening up to quantitative modelling, and thus to mathematics, but mathematicians are not very active in this process.  Perhaps it is time to reassess the priorities of our subject and ensure that mathematics is indisputably a force for good, or at least for progress in the world.

I am a mathematician at Imperial College London.  In September I attended the World Knowledge Dialogue in Switzerland, a meeting intending to bridge the gap between the natural and the human/social sciences.  From Nobel laureates to former UN High Commissioners, the speakers laid down a clear challenge to all intellectuals to become engaged in addressing the worlds problems.  The central issue was described by the Harvard biologist E. O. Wilson as how humanity can deal with having:

Stone-age emotions and medieval institutions combined with god-like technology.

I was presenting a poster on how mathematical art could be used to inspire people to put in the work required to learn mathematics.  A worthy cause, maybe.  It was, however, flawed by a false assumption: that the delegates believed that mathematics and mathematics education had a key role to play in solving the world’s problems.  Many did not, due in part to a perception, extending even into the life sciences, that the work of mathematicians is esoteric, and only useful in limited situations.  For this we must accept some portion of the blame.

Up until the middle of the 19th century mathematicians, like Gauss and Euler, were primarily motivated by the quest to describe and resolve physical problems. Today, however, the primary goal for many mathematicians has moved from utility to the sense of mathematical beauty described in Hardy’s A Mathematician’s Apology.  This beauty is a wonderful concept and it cannot be denied that there have been great discoveries that have later found practical applications.  The importance of Hardy’s number theory in internet commerce is a prime example.  In the quest for beauty, especially when combined with powerful tools for generalisation from Hilbert on, the wonderful practicality of mathematics has not quite been lost, but has been buried. 

To me mathematics is the study of ideas without reference to the real world.  This is part of the problem, mathematics is indeed esoteric.  However consider an effective model of the world.  To have predictive power this model must be able to run without constant reference to the situation it is modelling.  Mathematics, therefore, is the only language in which we can model anything.  While the success or failure of a model depends on its design not its mathematics, without mathematics there can be no quantitative models.  In the sixteenth century the telescope allowed many measurements to be made that had previously been impossible.  This led to the first great discoveries of physics: simple mathematical models to make sense of the observations.  We are seeing a similar process in the explosion of data available through computers and the internet.  This has opened many areas to quantitative study and potential modelling.  We are also discovering the rich data within DNA (and protein) sequences in biology.  In just ten years it is predicted that sequencing a whole genome will cost just £10.  The areas in which complex mathematics is of use are therefore widening rapidly.

The practicality of mathematics can only be revealed through communication.  It is no longer true, if it ever was, that anyone with a problem that could benefit from mathematics will search to find the correct mathematical language and approach mathematicians with the problem formulated for us.  It is therefore our responsibility to become active.  To remember that utility, not just beauty, should be the goal of good mathematics.  To go into the common rooms of universities, to international conferences and into the world and make contacts in other subjects.  To listen to the problems that other intellectuals are tackling.  To find where there are mathematical solutions and explain the things that mathematics can (and cannot) do.  Essentially, to find mathematical applications outside the traditional areas, other than those motivated by a desire to make money.

I admit that this pushes mathematicians into something at which we are famously bad.  Too few of us are able to give a good picture of our research to other mathematicians, let alone general intellectuals or the public. In many ways we live up to the public perception of being brilliant but engaged in puzzles that are hard to understand and only of moderate use.  We must try to address this and not accept the public perception as fact.  As well as our personal responsibility to learn to communicate, we need to increase the importance of communication in the mathematical education.  To initiate teaching of communication and send the message, to undergraduate and graduate students alike, that communication is a necessary and honourable part of our profession.

It is true that there are many mathematicians pushing the limits of the subject’s applications already.  However in many cases the drive comes more from universities and the need for funding than professional interest.  The area of mathematical biology for example often carries a slight stigma.  This is made worse by the fact that much of the research carried out here is not good mathematics but more importantly is not good biology either.  The research driver is too often old mathematical questions that can be written in a biological language.  The challenge is, therefore, not to look for new applications for current research but to be willing to listen to the problems in other fields.  In some cases a solution will be ready, perhaps with an imaginative application of classic mathematics.  In others mathematics will be of no use.  However a few such problems might call for the development of entirely new mathematical models.  Who knows, they might even be beautiful!
