Length contraction is the phenomenon that a moving object's length is measured to be shorter than its proper length, which is the length as measured in the object's own rest frame. [1] It is also known as Lorentz contraction or Lorentz–FitzGerald contraction (after Hendrik Lorentz and George Francis FitzGerald ) and is usually only noticeable ...
The first edition of the book was published in 1960. Until the 10th edition, the author was Campbell R. McConnell, professor of economics at the University of Nebraska, Lincoln, and since the 11th edition, which was published in 1990, Stanley L. Brue, a professor of economics, has become a co-author.

The so-called Length contraction without expansion perpendicularly to the line of motion and by the precise value = / (where l 0 is the length at rest in the aether) was given by Larmor in 1897 and by Lorentz in 1904. In the same year, Lorentz also argued that electrons themselves are also affected by this contraction.
The hemline index is a theory that suggests that skirt length (hemlines) rise or fall along with stock prices. The most common version of the theory is that skirt lengths get shorter in good economic times (1920s, 1960s) [1] and longer in bad, such as after the 1929 Wall Street crash. However, the reverse has also been proposed with longer ...
For instance, Bell argued that the length contraction of objects as well as the lack of length contraction between objects in frame S can be explained using relativistic electromagnetism. The distorted electromagnetic intermolecular fields cause moving objects to contract, or to become stressed if hindered from doing so.
Other economics handbooks, whether general or specialized, may come from publishers as part of a series beyond extending economics [11] or on ad hoc basis. [ 12 ] A Google Scholar "economics handbook" search indexes the range of topics treated, as does a New Palgrave Dictionary of Economics Online article search by topics, using the JEL ...
Transformation problem: The transformation problem is the problem specific to Marxist economics, and not to economics in general, of finding a general rule by which to transform the values of commodities based on socially necessary labour time into the competitive prices of the marketplace. The essential difficulty is how to reconcile profit in ...
In microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.
