The prisoner of polygonia

Plus doesn't usually report on primary school maths, but we couldn't resist telling you about a beautiful new maths play for key stage 2 students, which premiered today at the Royal Institution. In the land of Polygonia, where maths is the official language, Rhombus the maths wizard is falsely imprisoned on the orders of Queen Parabola. Data, a ten-year old girl, is the only witness. Before she can help him she must learn to speak the language of maths — and work out why the queen hates anyone who tries to make maths exciting.

Today's two performances, each in front of a full house, proved a great success with audiences made up of students from year 3 through to year 7 and their teachers. With their help, and plenty of laughs, Data managed to solve the puzzles facing her in her mission to save Rhombus, encountering prime numbers, number sequences, symmetry and more mathematical magic along the way. Data and the audience learn that no matter how difficult a maths problem looks, there's usually a trick which makes it simpler, and more fun.

The prisoner of polygonia was written by Phil Lowe and Rob Eastaway, founder of Maths Inspiration. Your next chance to see the show will be as part of the Wales Maths Week 2009 in Cardiff on the 1st and 2nd of October (call 029 20 475 476 for tickets). If you would like to arrange having the play in your area, visit its website.

What would you like to know about your Universe — The fifth online poll

This poll is now closed. The most popular question was: "Is time travel allowed?" We will publish the answer in an article on Plus shortly. Thank you for taking part!

This is the fifth online poll in our series to celebrate the International Year of Astronomy 2009. Choose your favourite question from the list on the right, and we'll put the one that proves most popular to world-leading astronomers and cosmologists, including Astronomer Royal Martin Rees and author and cosmologist John D. Barrow. The poll will remain open for a month and the answer will be published in a Plus article and podcast soon after. If your most burning question is not on this list, then leave a comment on this blog and we'll endeavour to include it in a future poll.

The winning questions in our previous polls have been

the nature of the universe and consciousness

INTRODUCTION

What is the nature of the universe and consciousness ?

How is the material constructed ?

That is the problem concerning to the humankind for a long time. And we always thought that the universe is created from the elementary particles, but perhaps we also always agree with Geoffrey Chew’s idea : “A truly elementary particle – completely devoid of internal structure – could not be subject to any forces that would allow us to detect its existence. The mere knowledge of a particle’s existence, that is to say, implies that the particle possesses internal structure!” (1).

And it must be completely homogeneous, each its debris must be intact itself not different, it could not be subject to the space and time

With that particularities, the elementary particle could not exist in the our world, even though in the subatomic world.

So, why do we always thought that it must be a smallest particle?

Why can not it be an unlimited one, contains all motive laws of the universe?

And there is only the unlimited one that contains all the particularities of an elementary particle.

Therefore, universe is just one the unlimited and homogeneous entity, with an inherent internal energy in oscillations form, in which, the material is mere the sets of internal oscillations of that entity.

When talking about the theory of evolution and the age of the earth and it's inhabitants, no one ever wants to talk about the lose of speed in the spin of the earth. How many years back would the spin of the earth be so great that no person could remain on the surface because gravity could no longer hold them down and/or the wind sheer would be so great that the surface would begin to become smooth? This would definitely have a lot to do with the age of mammals on this planet.

The earth was not very different from today when mammals evolved less than 200m years ago!

I have two questions I would like to see discussed:

1) What is thought to have taken place before the big bang? What caused it? Did something exist before then that collapsed, much like a star does under its own gravity before becoming a supernova?

2) What is thought to be occurring on the edge of the universe? I guess the bigger question is, do we have an idea about the shape of our universe?

Hi there,

The answer to the first question has been explored in a Plus article. For an answer to the second question, please tick the corresponding box in the current poll.

The Nature Autumn '09 Debate — Science and the financial crisis

The 1980s saw the rise of the "rocket scientists" of finance — as engineers, mathematicians and physicists rejected careers in science and technology and instead opted to work for banks. What part did they play in the financial crisis? And what is the future of science in finance? Join leading experts from science and banking as they debate whether the crisis was the result of bankers and regulators failing to grasp complicated, expert knowledge; and whether scientific knowledge — in particular fields such as complex systems, ecological economics and human behaviour — could help to ensure that economies are better understood and better regulated. The panel includes Tim Johnson, an RCUK Academic Fellow in Financial Mathematics, and author of the recent Plus article What is financial mathematics?

The debate will take place on the 21st of September at Kings Place in London, and you can book tickets, at £9.50 a head, on the Kings Place website.

A Gömböc is a strange thing. It looks like an egg with sharp edges, and when you put it down it starts wriggling and rolling around as if it were alive. Until quite recently, no-one knew whether Gömböcs even existed. Even now, Gábor Domokos, one of their discoverers, reckons that in some sense they barely exists at all. So what are Gömböcs and what makes them special?

Particle physics isn't what you expect to find at music festivals, but this year visitors to the Secret Garden Party were treated to just that — and more — thanks to Guerilla Science, an initiative committed to bringing science to music festivals. An unusual mission, perhaps, but the talks, chats and hands-on sessions managed to pack out the tents.

In our third online poll to find out what Plus readers would most like to know about the Universe, you told us that you'd like to learn about the secrets of dark matter and dark energy. We took the second part of the question — what is dark matter? — to John D. Barrow, renowned cosmologist and Professor of Mathematical Sciences at the University of Cambridge. Here is his answer. (The first part of the question has been answered in Plus by Martin Rees.)

In my view, as the old stars die new will be born at all times whether or not the universe is expanding. The total matter in the universe must remain the same at all times and this includes dark energy and dark matter. Dark matter and dark energy could be transforming simultaneously into one another constantly maintaining the same dynamic ratio of dark matter to dark energy.

In my view, even the expanding universe, the fading away of old stars will result in the creation of new stars and therefore new galaxies. So there will NEVER be the so-called death of the universe whether or not the universe is expanding, contracting or static.
