Obama's anticipation and reflexes are gob-smacking. He is clearly the first Jedi president.
An article in the UK Telegraph highlights just what an accomplishment it is to score a direct hit on a fly. The insect can change course in just 30 thousandths of a second.
According to Professor Michael Dickinson of the California Institute of Technology in Pasadena, who has studied fly behaviour extensively, the most effective way to swat a fly is not to aim for its starting position, but anticipate where the insect is likely to jump when it first sees danger. This is no mean feat, as, when confronted by a predator (aka swatter), a fly rapidly initiates a manoeuvre, combining near-360 degree vision with complex postural movements, depending on the direction of the attack.
