In science:

In general, models based on nearest neighbour 1D and 2D geometries can provide only limited range of description of real life phenomena, where interactions between agents are usually long range and structureless.
Simple queueing approach to segregation dynamics in Schelling model
This is why the equations of space-time within GR return to the flat geometry of special relativity, corresponding to the Newtonian description of space, at large radial distances from a mass source.
Some Comments on the Tests of General Relativity
Physical observables associated with both matter and geometry simply diverge signalling a fundamental flaw in our description of Nature.

Holographic Entanglement Entropy: An Overview
We give only a sketchy description which lacks even proper definitions; one needs a serious course in algebraic geometry to treat these matters in a rigorous way.
Zariski decomposition: a new (old) chapter of linear algebra
A contains a description of our conventions and notation and of the geometry of the AdS4×C P 3 superspace.
String instanton in AdS(4)xCP(3)
In Section 6.3 we mentioned that the three distinct geometries describing the simple, deformed and resolved conifold are, in the exact string theory description beyond the leading supergravity order, related by so-called geometric transitions.
Primordial Fluctuations in String Cosmology
The geometry description in Mokka is interfaced to GEAR for reconstruction and analysis.
Summary of the Linear Collider Testbeam Workshop 2009 - LCTW09
The reduced field structure near the planet is modeled in Section 3, and provides a description of the flow geometry in the region where the outflow is launched (see Figure 2).

Dust in dwarf galaxies: The case of NGC 4214
We stated the problem over Q, because most algebraic geometry is done over an algebraically closed field and we wanted the input to admit a finite description.

The study exploits the explicit description of compact Calabi-Yaus by means of toric geometry.
Models of Particle Physics from Type IIB String Theory and F-theory: A Review
Roughly speaking the gauge generators are lifted to a geometric description in F-theory, so that for example the 2-form flux with generator index in the 8-dimensional theory is lifted to a 4-form flux in a pure geometry background.
Models of Particle Physics from Type IIB String Theory and F-theory: A Review
We present at first the description of the target space geometry along the R-line of marginal deformations of the SU (2) WZNW model.

The main feature of these laws is their projective invariance, so they define a natural generalization of ordinary descriptive geometry for an interpretational case.
