Tiger
Woods Another Einstein?
So
just what is Tiger Woods's secret? Simple. It's Vc = 2D(1/T)(P1lk)(1-Pt2)
to the power of (1/k-1).
That, according to British and French researchers, is the
equation determining whether
you hole a putt rather than leave it short, overrun the
cup or lip out.
The
formula, published in the British scientific weekly 'Nature',
was calculated from observations
made of 10 good golfers, each with a handicap of less than
five.
The
key factors in successful putting are balancing Vc (the
clubhead velocity just before impact)
with D (the amplitude of the forward swing), T (the duration
of the overall swing) and P
(the duration before the ball is hit as a proportion of
the overall swing).
These
factors depend on a golfer's assessment of such things as
the speed and slope of the green,
which could affect the ball's path.
Cathy
Craig, a researcher from County Antrim, Northern Ireland
who lectures at France's University
of the Mediterranean in Marseilles, said the key to implementing
all these factors lies
in the nervous system. She explained that it was a "timing
mechanism" in which the brain visualises
the movements that have to be made and assesses the time
that is needed to perform
them.
Rather
as someone who is listening to music can predict the next
beat, this mechanism determines
the amount of time needed to close the gap between putter
and ball (the backswing)
and the time needed for the follow-through. Similar timing
processes are used when
people have to catch a ball or play tennis.
The
golfers were tested in laboratory conditions, putting on
Astroturf towards lines drawn one, two,
three and four metres away. In
an age when the coefficient of restitution determines the
legality of metal drivers, the time will
shortly come when golfers will need log tables in their
bags as well as a copy of the Rules of
Golf.
