Nikoletopoulos introduced long range order to this model by applying it to a small world graph. It can be used to model nucleation processes in the "critical droplets" theory, and general cases can be attacked by the Metropolis algorithm with a Boltzman distribution. Its three-dimensional form was proven to be computationally intractable by Istrail, and it was solved by Lars Onsager in the two dimensional case, where its critical value is two over the natural log of one plus the square root of two. It is a specific case of the Potts model, and if the value of J in this model is negative, it results in the opposite of the effect usually associated with it. It its most famous application it replaces intermolecular interactions with a grid of spins, which can only be up or down, and the energy is considered to be the sum of their interaction with each other and with an external magnetic field.

[10] If a vertex unit is this with respect to BH, it can replaced BH in the electron count. In general, this word refers to groups which have similar frontier molecular orbitals.
Answer: Isolobal

It's most useful on large programming projects with many developers to facilitate refactoring and modularity. For 10 points each,
[10] First, name this tenet of object oriented programming which dictates that one ought hide the internal workings of a class as much as feasible.
Answer: Encapsulation
[10] In a GUI [pronounced goo-ey], this is the name given to the paradigm that the program reacts to specific inputs from the user. It differs from earlier procedural programming styles because it is non-blocking.
Answer: Event Driven Programming [accept anything containing Event that sounds close]
[10] Event Driven programs often rely on this method of splitting up a programs tasks. One of the namesake constructs is created every time the user interacts with the program, though it often terminates quickly.
Answer: Multithreading [accept word forms, be nice and accept parallelism]

Andre Geim studied the paramagnetic version of this effect, while the dual version of this effect is responsible for color confinement in some gauge theories. FTPE:,
[10] Name this effect, a form of perfect diamagnetism in which a Type I superconductor expels any externally applied magnetic field.
Answer: Meissner-Ochsenfeld effect
[10] This pair of differential equations can be used to give the penetration depth of the Meissner Effect in terms of the applied magnetic field.
Answer: London equations
[10] In a type II superconductor, impurities lead to this "trapping" of magnetic field lines such that they do not move under the Lorentz force.
Answer: Flux pinning
