Entities in the world are assumed to be two stages removed from the familiar systems
on which the
model is based: (1) gas molecules are not the «tiny elastic
spheres» of the
model (if we are not naive realists), and (2) «tiny elastic
spheres» are not billiard balls (if we have kept negative analogy in mind).
Generalizing the standard
model of flocking motion to the curved surface of a
sphere rather than the usual linear plane or flat three - dimensional space, Bowick's team found that instead of spreading out uniformly over the whole
sphere, arrowlike agents spontaneously order into circular bands centered
on the equator.
Limited by the era's computers and understanding of physics, Wilson's
model relied
on simplifications — such as the star being a perfect
sphere — and incorrect assumptions about the behavior of very dense matter and how neutrinos move from the core's interior to the crucial outer parts where the heating of the shock wave occurs.
However in parallel to their practical experiments, the researchers have been running calculations
modelling the process
on their computers and have thus been able to simulate the «capturing of light» in the tiny
spheres.
There is another factor I don't think is captured in this
model - the issue of outside factors
on each of the three primary colored
spheres.
Furthermore, it's the first tablet to run Android 4.2, which brings with it great new features — Photo
Sphere, which lets you capture a three - dimensional
model of a real - world space, is one of the coolest I've ever experienced
on a tablet.
The functions form an orthonormal basis
on the
sphere, so the mathematical properties of the representation are well understood (indeed, it seems to be used in the climate
models).
Current development is focused
on the Cubed
Sphere grid and dynamical core to improve the
model simulations at higher resolution.
By picking one specific area of only one of the
spheres (surface temperatures), while it might be one piece of interesting information and it certainly it is quite true that surface temperatures have been flat at or near record high levels, focusing
on this fact alone and the fact that climate
models failed to have forecast it, does very little overall good if the goal is to educate the public about the bigger picture, i.e. anthropogenic climate change as an energy imbalance affecting the whole Earth energy system, including all the
spheres discussed above.
We don't even have the data needed to intelligently initialize the
models we have got, and those
models almost certainly have a completely inadequate spatiotemporal resolution
on an insanely stupid, non-rescalable gridding of a
sphere... the ongoing failure of the GCMs to actually predict or hindcast anything at all particularly accurately outside of the reference interval.»
