Memo to all teams playing Belgium in the World Cup this year: don't let them use their own coins for the toss.
Mathematicians say the coins issued in the eurozone's administrative heartland are more likely to land heads up than down.
While the notes which began circulating in the 12 members of the eurozone on January 1 are all the same, the coins show national symbols on one side and a map of Europe on the other. King Albert, who appears on Belgian coins, appears to be a bit of a lightweight, according to Polish mathematicians Tomasz Gliszczynski and Waclaw Zawadowski. The two professors and their students at the Podlaska Academy in Siedlce spun a Belgian one euro coin 250 times, and found it landed heads up 140 times. The cent coins proved even more likely to land heads up.
