«Spin models are not only used in physics, but also to
model other complex systems, such as neural networks, proteins or social networks.

Though
other mathematical
models are capable of simulating
complex phenomena, only Darwin's approach shows how certain
complex systems not only arise but also adapt over time to the constraints imposed by their environment, as living
systems do.
Initiated in 2002, QuakeSim uses NASA remote sensing and
other earthquake - related data to simulate and
model the behavior of faults in 3 - D both individually and as part of

The CCP is engaged in numerous multidisciplinary projects in
other model systems (e.g. fly, zebrafish, yeast) that aim to determine how
complex molecular circuits function and evolve in response to genetic and environmental changes, cellular differentiation, evolution and disease.
Finally, in a collaboration with Frank Jülicher's group at the Max Planck Institute for the Physics of
Complex Systems, we are using these data to develop physical
models that will help us understand how local cellular adhesive, elastic and contractile properties are influenced by PCP proteins and
other molecules, and how they combine to produce specific packing geometries at a global level.
The Marvel paper criticizes Lewis and
others for using a «spherical cow» type of
model to represent a
complex system.
So it seems to me that the simple way of communicating a
complex problem has led to several fallacies becoming fixed in the discussions of the real problem; (1) the Earth is a black body, (2) with no materials either surrounding the
systems or in the
systems, (3) in radiative energy transport equilibrium, (4) response is chaotic solely based on extremely rough appeal to temporal - based chaotic response, (5) but at the same time exhibits trends, (6) but at the same time averages of chaotic response are not chaotic, (7) the mathematical
model is a boundary value problem yet it is solved in the time domain, (8) absolutely all that matters is the incoming radiative energy at the TOA and the outgoing radiative energy at the Earth's surface, (9) all the physical phenomena and processes that are occurring between the TOA and the surface along with all the materials within the subsystems can be ignored, (10) including all
other activities of human kind save for our contributions of CO2 to the atmosphere, (11) neglecting to mention that if these were true there would be no problem yet we continue to expend time and money working on the problem.
Experience with solution algorithms, data assimilation methods and tools, coupling of components and processes, nonlinear and linear solvers, limiters, and / or

There are
other methods for using several data series when the physics of a
system is too
complex; they avoid dealing with «
models embodying the laws of physics... with parametrization of the water vapor cycle» and provide convenient checks.
Other scientists believe that the
models are not accurate because the Earth
system is too
complex and important factors such as clouds can not be accurately included.
That is, on the one hand, why people try to develop
models, and on the
other hand, why
models often fail (and why I can't cast much blame on those who have failed to adequately
model such a
complex system).
There is a debate, however misguided you feel the
other side may be, because some parts of the
complex system being
modeled are behaving in a manner that is somewhat confusing.
The ability of dynamic
