The language of symmetry in Islamic Art

The monthly Maths-Art seminars at the London Knowledge Lab, that explore the connections between mathematics and art, arose out of the Bridges Conference held in London in 2006. In the next seminar, Richard Henry, an artist and teacher with a specialism in Islamic geometric tiling, will talk about practical geometry and the language of symmetry in Islamic art.

"My work draws considerable inspiration from Islamic art, its history, craft techniques and geometrical ideas," says Henry. "I have a deep interest in the mystical philosophy that underlies the art and how this influences the design of Islamic buildings, with their special sense of sublime tranquility that is often experienced. In explaining these I will present images from an extensive field study that I carried out in Iran. I will also discuss the occurrence of non-periodic tilings in medieval Iranian designs, and how these are related to the modern mathematical theory of Penrose tilings."

The methods Henry uses to create his beautiful images are based on some of the earliest geometric methods used in mathematics: "I am particularly interested in practical geometrical methods, using compass and straight edge, for pattern construction for artists and craftspeople, and have explored these in my own works in painting, print and tile-mosaic. In this talk I will illustrate some of these methods for setting out patterns."

The seminar is on Tuesday 13 October 2009, from 6-7.30pm, at the London Knowledge Lab, 23-29 Emerald St, London, WC1N 3QS (travel information & maps). Everyone is welcome and no reservation required, but an email to would be appreciated for planning purposes.

You can read more about geometry and art on Plus, including the articles on Roger Penrose and Penrose tilings.

This isn't new. Jacob Bronowski commented on symmetry in Middle Eastern art back in 1973, in his acclaimed BBC series, The Ascent of Man.

Getting physical with maths

There's a significant intersection between sport fandom and science geekdom, and to address it, John D. Barrow, Professor of Mathematical Sciences at the University of Cambridge, will give a free public talk on physics and sport at the Cavendish Laboratory in Cambridge. Barrow will look at some applications of physics and simple mathematics to a variety of sports, including aspects of weightlifting, rowing, throwing, jumping, drag car racing, balance sports, and track athletics. He'll also explore some of the paradoxical systems of judging used in ice skating, and the effects of latitude and air resistance on some performances.

The talk will take place on the 13th of October at 6pm in the Pippard lecture theatre at the Cavendish Laboratory, Madingley Road, Cambridge.

Do you know if this talk will be recorded? Would be great to listen to.

Are you a winner?

If you're between 11 and 18, live in the UK and have just completed an interesting maths, science, engineering, or technology project, then why not enter the National Science and Engineering Competition?

The best entries will be invited to present their project at the Big Bang: UK Young Scientists’ and Engineers’ Fair, in Manchester in March 2010. You’ll have your own stand to show off all your hard work to over 13,000 scientists, engineers, students, parents, employers, teachers and celebrities. Plus you may even be chosen to face a VIP panel in the competition finals.

There are over £50,000 in prizes up for grabs, including cash awards and trips abroad. And entrants in the senior category could be crowned the UK Young Scientist of the Year or the UK Young Engineer of the Year.

It doesn't matter if your project has already been entered into another competition, you're still eligible, but hurry up, the closing date is October 30th!

The image above shows last year's winners Peter Hatfield (left) and Chris Jefferies (right).

Maths is the new black

We at Plus have always known that maths is beautiful, but now even the most aesthetic of worlds, fashion, is taking note. Last week in The Independent, Professor Sandy Black, from the Centre for Fashion Science, London College of Fashion, explained how her mathematical background has enabled her to create complex and unique knitted designs, selling in the most prestigious stores in London, New York and Tokyo.

Black also wrote about some of the exciting future possibilities resulting from weaving together science and fashion. Digital body scanning might not only produce made-to-measure clothes, but might even mean you never have to enter a cramped changing room again and instead virtually check the fit of those new jeans. Wonderland, a project funded by EPSRC that brings together designers and chemists, has created dresses that dissolve in water and packaging that can be turned into a gel used to grow seeds. You can read more in her article.

And if you can't wait for your mathematical fashion, maths has even made it into the Selfridges window display, as photographed last week by Dr Brian Stewart.

The links to your images have the wrong domain name on them. I don't see them in my browser because my proxy server won't go to port 2004. works perfectly well though.

Thanks for pointing this out, Paul, we have fixed it!

As part of our celebration of the International Year of Astronomy 2009 we brought you the article How does gravity work?, in which Bangalore Sathyaprakash takes us from Newton's theory of gravitation to Einstein's general theory of relativity. Now hear Sathyaprakash explain gravity in his own words in this podcast.

Listen to the podcast.

If this has whetted your appetite for astronomy, then why not take part in our current online poll to nominate the next question we'll put to the experts.

In our fourth online poll to find out what Plus readers would most like to know about the Universe you told us that you'd like to find out how gravity works. We took the question to Professor Bangalore Sathyaprakash of the School of Physics and Astronomy at Cardiff University, and here is his answer. This interview is also available as a podcast.

If you'd like to put another Universe question to experts, vote in the current poll, or leave a comment on this blog.

Thanks for this interesting article - but I do find the paragraph below confusing. My first problem is the sentence: "But according to Newton's gravity, the effect of the Sun's vanishing would be felt immediately, as the Earth would fly away in an tangential direction to its original path." Does this vanishing refer to sight? If so, this has nothing to do with gravity.

"According to Newton's theory, gravitational interaction is instantaneous. Suppose the Sun were to vanish from the horizon today. We would not notice its disappearance immediately just by looking at the Sun, because light takes some time to travel. But according to Newton's gravity, the effect of the Sun's vanishing would be felt immediately, as the Earth would fly away in an tangential direction to its original path." Einstein's special theory of relativity, however, states that nothing, not even information, can travel faster than the speed of light. "It's possible to use the vanishing Sun analogy to construct [theoretical] gravitational telegraphs which would transmit information instantaneously — and that, according to Einstein, is impossible. That's the reason why Einstein had to reformulate the theory of gravity." Einstein published his reformulation in 1916, under the name of general relativity.

To clarify: no, here "vanishing" doesn't refer to sight. It refers to the Sun being actually removed, and with it its gravitational pull.
