The Code: Revealing the secret
When I was 12 my maths teacher took me aside after one lesson and let me into a secret that changed my life forever.
Mathematics, it turned out, was more than just the long division we were practicing in the classroom.
He started to tell me fantastic stories that were written in the language of mathematics.
He revealed to me a hidden code that explained why the world looks and behaves the way it does.
But not only that. By tapping into Nature's code he explained how we have been able to change our surroundings, build extraordinary cities and develop amazing technology that has resulted in the modern world we currently live in today.
Mathematics, he told me, is the code that makes sense of our universe.
In my new series for Ö÷²¥´óÐã Two called The Code, I hope to let everyone in on that secret code of mathematics that my teacher shared with me behind the back of the maths block.
The Code changed the way I see the world and I hope this series will let you see things through the eyes of a mathematician.
We travel to animation to reveal how the film-makers are using mathematics of fractal geometry to create the virtual worlds of films like and .
We interview an ex- agent who uses mathematical equations to locate serial killers.
We witness a plague of in which only happens every 13 years, a which the cicadas cleverly used to avoid other species in the forest.

Marcus du Sautoy learns about the periodical cicada
And we discovered how the mathematics of pattern searching helps you to become the world champion.
Hopefully after you've watched The Code you'll never look at mathematics or the world in the same way again.
But what makes this series so unique is that it is more than just a television programme.
Running alongside the programmes is an exciting mathematical treasure hunt full of engaging puzzles, addictive online games and clever conundrums that will take you on an exciting mathematical journey of discovery.
Called the Code Challenge it is an experience that combines the intrigue of solving a murder mystery with the addictive playfulness of .
For me, mathematics is not a spectator sport. The best way to appreciate and get excited by the power of this extraordinary subject is by immersing yourself actively in its world.
The Code Challenge is a fantastic way to play and explore the mathematical language of the universe.
And not only is it fun to play but there is a unique and valuable prize awaiting one talented player.
So join me on my journey and let me reveal to you what mathematics is really about.
Marcus du Sautoy is a professor of mathematics and the presenter of The Code.
The Code is on Ö÷²¥´óÐã Two and Ö÷²¥´óÐã HD on Wednesday, 27 July at 9pm.

Also, there was at least one factual error, when Prof. du Sautoy stated that no matter how big a circle you draw, the circumference divided by the radius equals pi. This is only true if the circle is drawn and measured in a plane. A huge circle drawn on the surface of earth, and measured on the surface, will have a ratio of less than pi.

The Code – Ö÷²¥´óÐã2, 27 July 2011
I found the programme "The Code" very interesting. I wish to offer two comments as follows:
1. Pi:
Pi (π) is known as a transcendental irrational number and, in theory, it does not have a definite and singular value. In practice, however, a value of 3.1416 is generally accepted. A value of Pi (π) is obtained by approximating the circle as a polygon with straight-line sides, a process that does not really accord with the purist principles of mathematics. If one uses a triangle, value of π will be 2.598. The value will increase to 2.828, 3.000, 3.061 and 3.131 for approximation of a circle with polygons with 4, 6, 8 and 20 sides. The increase will get smaller and smaller, and will virtually flatten off after, say, a 20-sided polygon. A value of 3.14 will be reached with a polygon with 56 sides and. a 120-sided polygon will give π as 3.1412.
2. Negative numbers
Arithmetical multiplication of numbers is a repetitive addition. However, application of a sign to the number changes the process into a statement, requiring association of meaning to a sign - plus (+) meaning forward or in credit or better-off and minus (-) meaning backward or in debit or worse-off.
For example, (-3)x(+2) means asking for the result of "giving away (-)" £3.00 every day after two days in the future (+). Here, the sum of £3.00 has a negative sign and the period of two days in future has a plus sign. The answer (-6) means that one would be £6.00 "worse-off (-)" in two days time. Similarly, with the rate of giving away three pounds per day (-3),one would have been £6.00 better-off (+6) two days ago (-2).
Yours faithfully,
Dr Satish Desai

Frankly, as a chemist and statistician (which means that I can do some maths, but the only analysis I can manage is in a laboratory), I found it interesting and, in part, amusing. It was, to me, a little light relief.
My wife, who claims not to have any mathematical ability nor interest (fine art is her hobby), was intrigued and watched it through. It probably taught her more maths than all of the previous correspondants together could manage in a month of Sundays.
Sure, for mathematical/scientific professionals, it was fairly light - though I would say it has plenty of interest even though it's not cutting edge. For most of the public, or at least those with an average or above IQ, it was probably ground they've never trod before.

What I wondered was "If our seconds were longer of shorter than they are today - they are after all a historically arbitrary division of an average day length - would the frequency ratios still have the same nice today fractions that we have today.

2. OK so pi crops up in many other areas besides geometry. However no attempt whatever is made to explain how it fits in to predicting the weight of the largest fish, for example. Do I take it no one has the faintest idea? Or is it just too difficult for the lay person to understand?
3. Likewise we have to take it on trust that imaginary numbers are used in radar and no attempt is made to explain how this works.
Indded, De Sautoy expects us to take so much on trust that I begin to wonder why he does not reconsider his atheism and at least allow for the possibility that the mystery is best explained by the existence of a supreme intelligence.

What we also need (this week) is the ability to model disorderly group behaviour - predicting when a "tipping point" (or riot in media terms) might occur. Presumably the buffer zone cancels out with lots of group members rather than one, though other stablising factors such as the number of police available to respond would also need to be included. Using an average to determine public service numbers may mean that you can't cope when things get chaotic. A successful model might suggest different tactics by the public services to deal with any troubles. All I know is the maths is way beyond me!

There were many things to relish in this series, and while as one who uses calculus not infrequently, I'd have liked to see more hard maths there, there were a number of elements of considerable interest, despite the padding.
The real fault comes from the title- by calling it "The Code", it seems to mark it as inaccessible to the masses, as if it's only a glimpse through an open door to a secret world of those who do the maths for us, to tell us it's all OK. A lot of scientists fall into that mode; Richard Dawkins for example, who tells us it's all known and clear, but don't open the door enough to allow interrogation of the tricky bits.
I am sure, however, that this was not du Sautoy's intent- he comes across as warm and engaging, and hopefully will try again.
Even so, as far as documentaries are concerned, a highlight in an otherwise rather barren year, where the Ö÷²¥´óÐã's prize jewel is often held up as the completely infantile Top Gear.

I think Marcus du Sautoy was referring to the (discrete) Logistics Map: , but he should have explained that P is not the population (in his equation), but P = population/carrying capacity, so P is between 0 and 1, inclusive, a sort of normalised population. Also, R is his equation is the growth rate that "does take into account the previous generation", i.e. if there are 100 lemmings and 5 new ones are born, R = 105/100, and not R = 5/100 (as one might think). This should have been explained as well. Otherwise, yes, the lemmings equation seems to be an ok way of modelling the lemmings populations, although it's just a model with many flaws as well (good, not perfect). The chaos comes from the fact that R might vary by very, very small amounts, but those tiny variations can cause wildly differing behaviour. It's not unpredictable if we know R, but what if we don't know R? The tiniest change / uncertainty in the value of R for lemmings for example, might lead to completely different populations / our predictions of the population.
More info here:
And here:
Overall, I think Marcus du Sautoy should be more "down-to-Earth" with maths, which is a wonderful subject, and not ruin it with mysticism ("the Code") , even if it might make some people pay attention to it. Yes, maths is cool and people should be told about it and shown how it can be interesting and exciting, but it's nothing voodoo/religious/mystical about it, anybody can do it, it makes sense (most of the time :-P), it's rational, positive and real (No, irrational, negative or imaginary numbers don't disprove my point!)
Also: he should be more clear when he is communicating maths, so that people like me and some other people puzzled about lemmings and the logistics map can follow him and can check that his equations actually make sense/work (without spending 30min on Google trying to figure it out). Suggestion: he should have called it the the logistics map, which is well known and studied (many things unknown about it: yes, "mystical"/"mysterious": no), and he should have explained what the terms are and what they mean (more clearly than what he did). Wouldn't have taken too long!
