Here is another test shot from my series based upon the General
Theory of Mortality a paper I found on NASA’s website when researching my ISTD
(International Society of Typographic Designers) brief. It is a difficult
project to sum up quickly but essentially it is trying to symbolise a complex equation
where life is represented through a ‘health frequency curve’ or energy level.
Here is a short extract for your enjoyment…
‘The difference between the forces of deterioration and
recuperation, i.e. the ratio which the net upward flow through rating r per unit
of time bears to f(x, r), will be called the "net force of deterioration"
and will be denoted by ø (x, r). Thus ø(x,r) = ø1 (x,r)-ø2(x,r). The net force of deterioration will in general be positive.
It may happen for some values of x and r to be negative, but for any given value
of r it cannot remain negative indefinitely, for if so the net upward flow
through rating r would always be negative, and the number of lives of rating
lower than r would increase continually, which is impossible since the lives
must die sooner or later. If our scale for measuring health is well devised,
the net force of deterioration will always be positive.’
