Scientists rule out running from the rain

UNIVERSITY SCIENTIST report in the journal Weather that it is
pointless to run, ending a dispute that has rumbled on for years.
A dash means spending less time in the rain, but you will be just as wet at the end
Of the trip, says Dr Stephen Belcher, a lecturer in meteorology. To come this
conclusion,
Dr Belcher and his colleagues observe that there are two ways in which
a person encounters each raindrop: ‘firstly the raindrops can fall directly on to the
top surface of the person,
and secondly, as the person moves, they will run into those
raindrops which are directly in front of them.’ However the surface area of the front of
an individual is much greater than that
of the head and shoulders. Using idealized
cuboids people to make the calculations easier, the team concludes that wetting
from passing through the rain is the domination factor. Only if we moved very slowly,
or were caught in an incredible storm, would it be a good idea to make a dash for it.

The scientists are baffled by why most people prefer to run, says John Holden, another
member of the team. He agrees that ‘this intriguing problem’ should know be passed to
the university’s psychology department. ‘Sometimes I do run, ‘he admits.
‘But I keep trying to tell myself that there’s no reason to.’The Daily Telegraph
