### Pi and mathematical reductionism

Last night I watched the film Pi (details here)

Here's the trailer.

It's a fascinating film. The 'hero' Max is a mathematical reductionist - and it screws him up. Idolatry does that.

### Turing on maths

This piece is taken from the play/ film 'Breaking the Code'. The screenplay was by Hugh Whitemore based on Alan hodges biography. Dilly Knox asks Alan Turing to explain in 'general terms' his research. This is Turing's response. It is a great summary of twentieth-century mathematics from Russell to Turing.

A few words of explanation ...in general terms?

Well, erm, it’s about right and wrong in ... general terms...It’s a technical paper in mathematical logic. but it’s also about the difficulty of telling wrong from wrong. You see people think, that well, most most people think that in mathematics we always know what is right and wrong, not so, not anymore. It’s a problem that has occupied mathematicians for forty or fifty years.

How do you tell wright from wrong?

Bertrand Russell has written a book on it his Principia Mathematica – his idea was to break down all mathematical concepts and arguments into little pieces and then show they can be derived from pure logic. Well it didn’t quite work out that way and after many years of intensive work all he was able to show was that it was terribly difficult to do anything of the kind; but it was an important book. Important and influential it influenced both David Hilbert and and Kurt Godel. It’s rather like what physicsts call splitting the atom. As analysing the physical atom has led to a new kind of physics so the attempt to analyse these mathematical atoms has led to a new kind of mathematics.

David Hilbert took the whole thing a stage further. I don’t suppose his name means much if anything to you? Wel there you are you see, it’s the way of the world people never really seem to hear about the really great mathematicians. But Hilbert looked at the problem from a completely different angle He said that if we are to have any fundamental system for mathematics, like the one Russell was trying to work out

It must satisfy three basic requiremts: consistency, compelteness and decidability.

Now consistency means you won’t ever get a contradiction in your own system, in other words you will never be able to follow the rules of your and end up with showing 2 + 2 = 5.

Completeness means that if any statement is true there must be some way of proving it by using the rules of your system

and decidability means, well decidability means that there must exist some method, some definite procedure or test which can be applied to any given mathematical assertion and which will decide whether or not that assertion is provable.

Now Hilbert thought this was a perfectly reasonable set of requiremtns to impose.

But within a few years Kurt Godel showed that no system for mathematics could be both consistent and compete and he did this by constructing a mathematical assertion, which said in effect: This assertion cannot be proved.

Classic paradox! This assertion cannot be proved. Well, either it can or can’t

If it can be proved we have a contradiction and the system is inconsistent

If it cannot be proved then the assertion is true. But it can’t be proved, which means the system is incomplete.

Thus mathematics is either inconstent or incomplete. It’s a beautiful theorm. It’s quite beautiful. I think Godel’s theorem is the most beautiful thing I know.

The question of decidabilty was still unsettled. Hilbert thought there should be one single clearly defined method of proving whether mathematical assertions were provable. The decision problem he called it the entscheidungsproblem. In my book on computable numbers I wanted to show that no one method can work for all questions, solving mathematical problems requires an infinite supply of new ideas. It is one thing to make this claim it is a monumental task to prove it. I needed to examine the provability of mathematical assertions past present and future. How on earth was it it be done?

Eventually one word gave me a clue – people had been talking a bout a mechanical process and process that could be applied mechanically to mathematical problems, a process without requiring any human invention or ingenuity – machine; that was the crucial word. I conceived the idea of a machine. A Turing machine which would be able to scan mathematical symbols, it read them if you like it would read a mathematical assertion and then arrive at a verdict whether that assertion was provable. I was able to show that Hilbert was wrong. My idea worked.

### Maths as rhyme?

I have recently read Vern Poythress's paper 'Mathematics as a rhyme'. Below are a few of my initial observations.

His idea as maths as a poem is an interesting idea, but I am not so sure as to how fruitful it is. It seems to be little more than Kepler/Galileo's idea that maths is the language of the universe.

I am not convinced of the metaphor of maths as a rhyme within the poem of the universe. It has too many resonances with the two books concept for my liking!

Not all poems rhyme!

If the poem is created by a poet, then the poet takes things he has not created (letters, words) to create the poem using rhyme etc. This suggest that God (poet) creates the universe (poem) using uncreated maths!

If maths is the rhyme what are the words?

He does makes some good points regarding mathematics; including:

Maths is a distinct science

It is not reducible to other sciences

Its regularities are a reflection of the faithfullness of God

There is at lest some degree of a posteri character within the knowledge of maths, even though it gives the impression that its truths are a priori

He subverts the view that maths is necessary rather than contingent. [ Though I would contend that it is necessary for creatures, but contingent for the Creator.]

Maths is personally structured [I'm not totally sure what he means here], for intelligibility there must be a personal interpreter.

There is a good discussion of reductionisms of logicism, formalism, intuition and empiricism - he shows the attractiveness of reductionism: "stimulating as a metaphor inadequate as ultimate explanation" [could this be said of maths as a rhyme within the poem of the universe?]

He shows the irreducibillity of the subparts of maths to one another.

### Maths website

I've just started another website. This one is devoted to maths education resources and can be found here. At present it is a list of web links for pre-GCSE, GCSE (ages 14-16) and A-level maths (ages 16-18).

### Is there a maths gene?

The University of Cambridge Department of Experimental Psychology is looking into the question: Is there a maths gene? At present they are looking for volunteers with Grade A at A-level, or a score of 700 or more on the maths section of the American SAT 1.

The project comprises two phases. In Phase 1 you will be asked to complete an online maths test. This will take about 20 minutes. You will then be asked to invite your siblings to participate, if they also have a Grade A maths A Level. In Phase 2, you will be invited to donate a DNA sample via a simple, quick and non-invasive cheek swab.

Once you and your sibling have both returned a DNA sample, you will be entered into a prize draw towin £250(or equivalent in other currency) worth ofAmazon vouchersto share. The draw will take place once data collection for this project is complete.

All participants must be aged 16 years or over. This study has been approved by the University Ethics Committee, all information remains confidential, and in Phase 2, DNA will be stored anonymously. You may withdraw your participation at any time without having to give a reason.

This though does raise the question -

*if*there is a maths gene, do we screen students before admitting them to A-level maths, or even before going to study a maths degree at university? That would certainly improve retention and achievement! Do genes really determine who we are?

There is no evidence to suggest that genes do determine who we are, although we are influenced by them. If they did determine who we are then someone with a kleptomania gene might be able to plead 'it wasn't me guv, wot did it, it was me genes.'

### Nestle get their maths wrong!

According to Nestle the makers of Smarties, Canadians eat enough Smarties to go round the Earth 350 times. A Grade 6 maths class in Ontario decided to put this claim to the test. It seems Nestle were wrong!

You can check their maths: according to Nestle Canadians eat 4 billion Smarties a year - the circumference of the Earth is approximately 40 000 km.

### Latin squares (aka Sudoku)

Sudoku (aka Su Doko, Sudoko, Soduko), is the latest craze to hit the UK . I first came across it about six months ago in a Times newspaper. The six out of the top 40 best sellers in The Guardian's bestseller's list are all Sudoko books! The concept is fiendishly simple: there is a 9 × 9 grid which is split up into nine smaller 3 × 3 grids, all the 3 × 3 grids, rows and columns must contain all nine numbers.

Sudoko apparently came to the

There are a number of Sudoko solvers on the web; books on how to solve them by, for example, Robin Wilson and Carol Voderman ; as well as books of them; and there is no shortage Sudoko puzzles on-line to have a go at.
