John Conway – discovering free will (part III)In this, the third part of our interview, John Conway continues to explain the Free Will Theorem and how it has changed his perception of the Universe.
Outer space: The answer to runnin' in the windRunners and cyclists can tolerate heat and cold but the thing they dislike most is wind. They know it produces slower times. Can we show them why?
The mathematics of your next family reunionThe festive season can only mean one thing... getting together with the family! You might not be able to choose your family, but at least now you'll know exactly what you share in common!
Decoding Da Vinci: Finance, functions and artDan Brown in his book, The Da Vinci Code, talks about the "divine proportion" as having a "fundamental role in nature". Brown's ideas are not completely without foundation, as the proportion crops up in the mathematics used to describe the formation of natural structures like snail's shells and plants, and even in Alan Turing's work on animal coats. But Dan Brown does not talk about mathematics, he talks about a number. What is so special about this number?
Understanding uncertainty: Visualising probabilitiesProbabilities and statistics: they are everywhere, but they are hard to understand and can be counter-intuitive. So what's the best way of communicating them to an audience that doesn't have the time, desire, or background to get stuck into the numbers? This article explores modern visualisation techniques and finds that the right picture really can be worth a thousand words.
Maths behind the rainbowKeats complained that a mathematical explanation of rainbows robs them of their magic, conquering "all mysteries by rule and line". But rainbow geometry is just as elegant as the rainbows themselves.
Join the celebration of mind!It's 21st of October and for puzzle lovers this can only mean one thing: the G4G Celebration of mind. This annual party celebrates the legacy of Martin Gardner, magician, writer and father of recreational maths, with mathemagical events in his honour happening all over the world.
Exploding stars clinch Nobel PrizeThis year's Nobel Prize in Physics was awarded for a discovery that proved Einstein wrong and right at the same time.
A fly walks round a footballWhat makes a perfect football? Anyone who plays or simply watches the game could quickly list the qualities. The ball must be round, retain its shape, be bouncy but not too lively and, most importantly, be capable of impressive speeds. We find out that this last point is all down to the ball's surface, the most prized research goal in ball design.
Meet the gyroidWhat do butterflies, ketchup, microcellular structures, and plastics have in common? It's a curious minimal surface called the gyroid.
Outer space: A very peculiar principleIf you manage a large organisation, then people will come and go. There are always decisions to make about promoting people, promising newcomers versus experienced middle managers, all of whom are aspiring to move up the corporate ladder. But is it better to promote the least competent rather than the most competent? Some new research suggests that it may be.
