Social Statics, or The Conditions essential to Happiness specified, and the First of them Developed is an 1851 book by the British polymath and economist Herbert Spencer . In it he uses the term fitness in applying his ideas of Jean Baptiste Lamarck Lamarck ian evolution to society, saying for example that It is clear that any being whose constitution is to be moulded into fitness for new conditions of existence must be placed under those conditions. Or, putting the proposition specifically it is clear that man can become adapted to the social state, only by being retained in the social state. This granted, it follows that as man has been, and is still, deficient in those feelings which, by dictating just conduct, prevent the perpetual antagonism of individuals and their consequent disunion, some artificial agency is required by which their union may be maintained. Only by the process of adaptation itself can be produced that character which makes social equilibrium spontaneous. Despite it commonly being attributed to this book, it was not until his Principles of Biology of 1864 that Spencer coined the phrase survival of the fittest , ref cite web url http www.darwinproject.ac.uk entry 5145 mark 5145.f3 title Letter 5145 Darwin, C.

unreferenced date December 2007 Libertarianism sidebar The law of equal liberty aka the law of equal freedom , or equal liberty , is a doctrine first named, though not first conceived, by Herbert Spencer in Social Statics 1851 which says that every man may claim the fullest liberty to exercise his faculties compatible with the possession of like liberty to every other man. Or, stated another way by Spencer, each has freedom to do all that he wills provided that he infringes not the equal freedom of any other. ref Herbert Spencer, Social Statics, c. 4, 3. ref This doctrine has been influential on political theorists, including classical liberals , libertarians and anarcho capitalists . Spencer derived the principle on a belief in the principles of scientific evolution. He believed that human happiness was an intrinsically developed emotion. He held that man s purpose can be obtained only by the exercise of his faculties and therefore that exercise must be a human right. Restraining the liberty of someone else prevents him from pursuing happiness. But, for this to be a universal ethic , that is, a moral code that applies to all individuals rather than just some, it would have to apply to all individuals. Therefore, if an individual restrains another individual from doing the same, then he has overstepped his rights. As a result, rights are equalized among all people. The law of equal liberty or freedom is closely related to Pareto efficiency which essentially states that any organizational allocation of resources that can at least make one person better off without making any other person worse off achieves Pareto optimality .

In structural engineering , the P or P Delta effect refers to the abrupt changes in ground shearing physics shear , overturning moment physics moment , and or the axial force distribution at the base of a sufficiently tall structure or structural component when it is subject to a critical lateral displacement vector displacement . The P Delta effect is a destabilizing moment equal to the force of gravity multiplied by the horizontal displacement a structure undergoes as a result of a lateral displacement. To illustrate the effect, take the example of a typical statics case in a perfectly rigid body subject only to small displacements, the effect of a gravitational or concentrated vertical load at the top of the structure is usually neglected in the computation of ground reaction physics reactions . However, structures in real life are flexible and can exhibit large lateral displacements in unusual circumstances. The lateral displacements can be caused by wind or seismically induced inertial force s. Given the side displacement, the vertical loads present in the structure can adversely perturb the ground reactions. This is known as the P effect. In some sense, the P Delta effect is similar to the buckling load of an elastic, small scale solid column given the boundary conditions of a free end on top and a completely restrained end at the bottom, with the exception that there may exist an invariant vertical load at the top of the column. A rod planted firmly into the ground, given a constant cross section, can only extend so far up before it buckles under its own weight in this case the lateral displacement for the solid is an infinitesimal quantity governed by Euler buckling.

A regular economy is an economy characterized by an excess demand function which has the property that its slope at any equilibrium price vector is non zero. In other words, if we graph the excess demand function against prices, then the excess demand function cuts the x axis assuring that each equilibrium is locally unique. Local uniqueness in turn permits the use of comparative statics an analysis of how the economy responds to external shocks as long as these shocks are not too large. An important result due to Gerard Debreu Debreu 1970 states that almost any economy, defined by an initial distribution of consumer s endowments, is regular. In technical terms, the set of nonregular economies is of Lebesgue measure zero. Combined with the Hopf index theorem index theorem this result implies that almost any economy will have a finite and odd number of equilibria.
