Dear Prof. Rosenberg:
(1) I read your article appeared in the recent New York Times (Reference (a)
above) with great interest.
(2) In one of para in it, you mentioned that
ÒEconomics employs partial differential equations ....Ó
I would greatly appreciate it if you can kindly inform me what are the
dimensions of those PARTIAL differential equations except time.
(3) In contrast to the aggregating approach as of the ÒLimits to the GrowthÓ at
the Massachusetts Institute of Technology (MIT), we are initiating the Global
Early Warning System (GEWS) (which is the previous name of the current Global
Knowledge Centers Network (GKCN)) (Reference (b) above) with the use of
distributed simulation methodology which I conceived at the 1971 Summer
Computer Simulation Conference (SCSC) in Boston.
As you see in it, we are interconnecting the distributed
socio-economy-energy-environmental simulation models scattered in various
countries through broadband Internet, which will then act as if a single global
model in a global scale virtual supercomputer (Figures 1 and 5 of Reference (b)
above).
With your way of thinking, this may be called a ÒPseudoÓ PARTIAL differential
equations (including ÒPseudoÓ DISTANCE dimension), but each of those models
(which are constructed by the System Dynamics methodology (which was initiated
by Prof. Jay W. Forrester of MIT)) are massively parallel simultaneous highly
non-linear ORDINALY differential equations, which are integrated along the
dimension of TIME.
(4) In your article, you mentioned as;
ÒThe fact
that the discipline of economics hasnÕt helped us improve our predictive
abilities suggests it is still far from being a science, and may never be.Ó
ÒNo one can predict the direction of scientific discovery and its technological
application. That was PopperÕs key insight.Ó
The aim of our GEWS project is NOT for the forecasting of future as the cases
of the ÒLimits to the GrowthÓ nor FUTUR-ICT Project at the University City
London with $1.3 billion from the European Union. We are more interested
in capacity building of bureaucrats and young aspiring future leaders for their
fostering scientific and rational thinking for policy analysis and evaluation,
as mentioned in the Reference (b) above.
Prof. Forrester once told me privately that the essence of system dynamics
methodology is NOT predicting future, but learning the intricacies of
inter-relationship among various world phenomena and that our distributed
simulation approach is the ENHANCED systems dynamics — these are very basic
necessities for the global intercultural education for attaining global peace.
(5) You also questioned the validity of calling economics as one of scientific
disciplines.
Pls browse the Reference (c) above, which I described
about my incidence when I questioned the same to the Late Dr. Shigeru Nambara, the Rector of the University of Tokyo, who was the
most prominent political science philosopher in Japan and a close friend to the
Late Dr. James Conant, the Rector of Harvard University.
I later found out that the Greek origin of the word ÒscienceÓ has the meaning
of Òto learnÓ or Òto know.Ó
I look
forward your prompt response.
Best, Tak
