Swatting flies
September 3rd, 2008
The reason you can’t swat a fly is that, for a creature with a brain hardly deserving of the name, the fly is a marvel of calculating ability. But before I explain what scientists led by Michael Dickinson of the California Institute of Technology (that would be the Dickinson whose e-mail is “flyman”) have learned about how the fly brain calculates the location of the looming swatter, formulates an escape plan and plants its legs in an optimal position to hop out of the way (all within about 100 milliseconds of spotting the swatter), let’s cut to the chase: the best way to swat a fly, Dickinson says, is “not to swat at the fly’s starting position, but rather to aim a bit forward of that to anticipate where the fly is going to jump when it first sees your swatter.” [...]
The executive summary: having a 360-degree field of vision is tremendously useful.
