Electric chargeElectric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative (commonly carried by protons and electrons respectively, by convention). Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
Inverse limitIn mathematics, the inverse limit (also called the projective limit) is a construction that allows one to "glue together" several related objects, the precise gluing process being specified by morphisms between the objects. Thus, inverse limits can be defined in any although their existence depends on the category that is considered. They are a special case of the concept of in category theory. By working in the , that is by reverting the arrows, an inverse limit becomes a direct limit or inductive limit, and a limit becomes a colimit.
Turkish peopleTurkish people or Turks (Türkler) are the largest Turkic people who speak various dialects of the Turkish language and form a majority in Turkey and the disputed state of Northern Cyprus. In addition, centuries-old ethnic Turkish communities still live across other former territories of the Ottoman Empire. Article 66 of the Turkish Constitution defines a "Turk" as: "Anyone who is bound to the Turkish state through the bond of citizenship.
Central limit theoremIn probability theory, the central limit theorem (CLT) establishes that, in many situations, for independent and identically distributed random variables, the sampling distribution of the standardized sample mean tends towards the standard normal distribution even if the original variables themselves are not normally distributed. The theorem is a key concept in probability theory because it implies that probabilistic and statistical methods that work for normal distributions can be applicable to many problems involving other types of distributions.
Human ActionHuman Action: A Treatise on Economics is a work by the Austrian economist and philosopher Ludwig von Mises. Widely considered Mises' magnum opus, it presents the case for laissez-faire capitalism based on praxeology, his method to understand the structure of human decision-making. Mises rejected positivism within economics, and defended an a priori foundation for praxeology, as well as methodological individualism and laws of self-evident certainty.
