The magic circle
From an early age we are drawn to circles. Give a toddler a crayon and chances are he鈥檒l draw a big fat sun, or a smiley face or a wheel. There鈥檚 something about this simple, geometric shape that fascinates us.聽And if we look carefully we鈥檒l find that circles influence most aspects of our lives. This is a fact not lost on Dr Jeffrey Giansuracusa, from Swansea University's Maths Department.聽 He's giving a lecture聽 - A Mathematical Meditation of the Circle - at the university's Festival of聽 Research event this week.聽He shares some of his ideas with Adam Walton聽on the circles, in maths, biology and astronomy聽that make the world go around.聽We'll also hear from聽two of his colleagues at Swansea,聽 Prof Prem Kumar and Prof Carlos Nunez from聽the Physics department. Circles could be said to feature in String Theory - though wiggly loops might be more accurate.聽 Certainly symmetry聽is important聽in physics. And Adam talks to聽Dr Jens Borum, an聽expert in聽freshwater biology about some mysterious circles found under the sea off Denmark. These circles are beautiful to look at, but their existence at all is remarkable.聽聽聽
