Chris Wright reports on phys.org the new goal line technology that will by used in Brazil. It is unhackable and ‘100%’ accurate. However, the final call is still up to the referees.
World governing body FIFA awarded the contract to the German company (GoalControl) 16 months ago and there will be 14 high-speed cameras at each of the 12 World Cup stadiums to determine if an attempt on goal has crossed the line or not.
There are seven cameras trained on each goal and the cameras each take 500 pictures per second, sending a “GOAL” message to the referee’s watch if the ball is in, GoalControl chairman Bjoern Lindner explained.
The week of the opening of the 2014 FIFA World Cup, Nature has put together a group of articles highlighting the successes and plights of science in South America. An intro editorial titled “Open Goal” describes the idea behind the featured articles:
And as the world focuses its attention on Brazil, Nature has taken the opportunity to widen the view with our special issue on science in South America.
It seems that science in South America needs support of many kinds, including attention from international scientists training, visiting, mentoring, and in some cases funding. This will help support good science in South America, as well put a stop to a brain drain in many of these countries.
Football fans in South America are used to seeing top players leave for abroad. Efforts to reverse the flow, in science as in sport, face great challenges. But they are a worthwhile goal.
Scientific Reports this month includes a timely article on the aerodynamics of different types of soccer balls, “Effect of panel shape of soccer ball on its flight characteristics.” The study included a kick robot that uniformly kicked each of the balls. Thought all soccer balls were the same? think again, “Soccer balls are typically constructed from 32 pentagonal and hexagonal panels. Recently, however, newer balls named Cafusa, Teamgeist 2, and Jabulani were respectively produced from 32, 14, and 8 panels with shapes and designs dramatically different from those of conventional balls. The newest type of ball, named Brazuca, was produced from six panels and will be used in the 2014 FIFA World Cup in Brazil.”
