3 unusual facts about Metcalfe's Law


Andrew Odlyzko

But since this linearithmic function does not grow as rapidly as Metcalfe's law, it implies that many of the quantitative expectations based on Metcalfe's law were excessively optimistic.

This law gives us a much higher for V for any large value of N than either Metcalfe's law or Reed's law, resulting in herd or hive like thinking, problem solving, and decision making.

Hydrogen atom

The solution of the Schrödinger equation (wave equations) for the hydrogen atom uses the fact that the Coulomb potential produced by the nucleus is isotropic (it is radially symmetric in space and only depends on the distance to the nucleus).

Interference lithography

A fundamental concern for using low-energy electrons (<<100 eV) with this technique is their natural tendency to repel one another due to Coulomb forces as well as Fermi-Dirac statistics, though electron anti-bunching has been verified only in a single case.

The BB condition has guided mathematicians and engineers to develop state-of-the-art formulations for many technologically important problems like Darcy flow, Stokes flow, incompressible Navier-Stokes, nearly incompressible elasticity.

Kopp's law can refer to either of two relationships discovered by the German chemist Hermann Franz Moritz Kopp (1817–1892).

Laplace's law

Young–Laplace equation, describing pressure difference over an interface in fluid mechanics.

Lepton

It determines the strength of the electric field generated by the particle (see Coulomb's law) and how strongly the particle reacts to an external electric or magnetic field (see Lorentz force).

Listing's law

Listing's law is not obeyed when the eyes counter-rotate during head rotation to maintain gaze stability, either due to the Vestibulo-ocular reflex (VOR) or the optokinetic reflex.

Malandragem

Those who practice malandragem (o malandro) act in the manner of the popular Brazilian adage, immortalized in a catch phrase of former Brazilian soccer player Gérson de Oliveira Nunes in a cigarette TV commercial (hence the name it was given: Lei do Gérson, or Gérson's law): “I like to get an advantage in everything.”

Maskless lithography

However, a fundamental consideration here is to what degree electrons from neighboring beams can disturb one another (from Coulomb repulsion).

Notable Jets alumni include Larry Robinson and two of his brothers, as well as Boston Bruins' Marc Savard.

Nancy Jacobs

During the 2007 session of the Maryland General Assembly, Senator Jacobs sponsored Maryland's version of Jessica's Law.

Nitrogen laser

After some time the electric charge in the avalanche becomes so large that following Coulomb's law it generates an electric field as large as the external electric field.

Nonelectrostatic electric fields

The striking difference between the two kinds of fields is that we cannot associate electric potential with points in such an electric field and that the work done by the electric force in such a field is not zero over a closed loop.

Parkinson's law

In that episode, an undersecretary of the Department, played by Ian Lavender, explains to the Minister that a certain county "has the smallest establishment of social workers in the U.K."

Plasma modeling

A kinetic description is achieved by solving the Boltzmann equation or, when the correct description of long-range Coulomb interaction is necessary, by the Vlasov equation which contains self-consistent collective electromagnetic field, or by the Fokker-Planck equation, in which approximations have been used to derive manageable collision terms.

Quasiparticle

Motion in a solid is extremely complicated: Each electron and proton gets pushed and pulled (by Coulomb's law) by all the other electrons and protons in the solid (which may themselves be in motion).

Sen. Joel Lourie (D-Columbia) played an instrumental role in arranging negotiations between those in favor of the bill and those representing the insurance companies, and in furthering discussions during intense deadline pressure.

Sand filter

In addition, particulate solids can be prevented from being captured by surface charge repulsion if the surface charge of the sand is of the same sign (positive or negative) as that of the particulate solid.

Screening effect

In solids, especially in metals and semiconductors, the electrostatic screening or screening effect reduces the electrostatic field and Coulomb potential of an ion inside the solid.

For instance, the traditional electro-static force described by Coulomb's law may be pictured in a simultaneous hyperplane, but relativistic relations of charge and force involve retarded potentials.

Reed's law

Other analysts of network value functions, including Andrew Odlyzko and Eric S. Raymond, have argued that both Reed's Law and Metcalfe's Law overstate network value because they fail to account for the restrictive impact of human cognitive limits on network formation.
