New Scientist Live – Maths v Sport

Come and see my talk at New Scientist Live on September 23rd as I explain how to take the perfect penalty kick, investigate whether or not humans will ever break the 2-hour marathon barrier, and examine how the Earth’s rotation affects sports as varied as Golf, Rowing and Cricket.

Wimbledon Tennis

Grab your rackets, your strawberries and cream and – as long as you’re old enough – a glass of Pimms; because here are the most important facts and figures from Wimbledon…

  • Rackets used to be made from wood but now carbon fibre is the material of choice
  • Top spin pushes the ball down towards the ground via the Magnus force, created by a difference in air pressure around a spinning ball
  • The balls are filled with Nitrogen gas at a pressure higher than the air outside, which causes the gas to leak out over time and is why the balls are replaced often
  • The winner of the coin toss decides if they want to serve first and statistics show that a coin has a 51% chance of landing on the side that was facing down at the start
  • 320,000 glasses of Pimms, 28,000 kilograms of strawberries and 10,000 litres of cream are sold over the fortnight – cheers!
