Like other Greek letters, it could face either leftward or rightward (  ), depending on the current writing direction, but, just as in Phoenician, the horizontal bars always faced in the direction of writing. Understanding why ε0 has the value it does requires a brief understanding of the history. Is Lithium considered a metal in astronomy? More generally, no physical constant with dimensions has physical meaning, because its value depends on arbitrarily chosen units.

The name of the letter was originally εἶ (Ancient Greek: [êː]), but the name was changed to ἒ ψιλόν (e psilon "simple e") in the Middle Ages to distinguish the letter from the digraph αι, a former diphthong that had come to be pronounced the same as epsilon. (mathematics)   (From the Hungarian mathematician Paul Erdos) A very small, insignificant, or negligible quantity of something. By convention, the electric constant ε0 appears in the relationship that defines the electric displacement field D in terms of the electric field E and classical electrical polarization density P of the medium. rev 2020.10.27.37904, The best answers are voted up and rise to the top, Physics Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. The uppercase Epsilon is not commonly used outside of the Greek language because of its similarity to the Latin letter E. However, it is commonly used in structural mechanics with Young's Modulus equations for calculating tensile, compressive and areal strain. is occasionally used in place of ϶ in informal cardinals.
And please explain why you think that. Standards Organizations worldwide now use "electric constant" as a uniform term for this quantity,[7] and official standards documents have adopted the term (although they continue to list the older terms as synonyms). While the original pronunciation of the Phoenician letter He was [h], the earliest Greek sound value of Ε was determined by the vowel occurring in the Phoenician letter name, which made it a natural choice for being reinterpreted from a consonant symbol to a vowel symbol denoting an [e] sound. 1.

[20] For each different choice of ke there is a different "interpretation" of Q: to avoid confusion, each different "interpretation" has to be allocated a distinctive name and symbol. There is also a 'Latin epsilon', ɛ or "open e", which looks similar to the Greek lowercase epsilon. [duplicate]. (language)   A macro language with high level features including strings and lists, developed by A.P. It doesn’t have any physical significance. I was reading some information about the constant of electromagnetism $\epsilon_0$ $[\frac{C^2}{N\cdot M^2}]$ and according to my understanding it is the … ϵ This equation notates how close to …
In one of the systems of equations and units agreed in the late 19th century, called the "centimetre–gram–second electrostatic system of units" (the cgs esu system), the constant ke was taken equal to 1, and a quantity now called "gaussian electric charge" qs was defined by the resulting equation. "Gaussian electric charge" is not the same mathematical quantity as modern (MKS and subsequently the SI) electric charge and is not measured in coulombs. Can humming a bar of music considered as copyright infringement. [2] In TeX, \epsilon ( {\displaystyle 1/4\pi \varepsilon _{0}} What is this oddly shaped hinged device with indentations? Dec 5, 2004 #5 chroot. Of the various minuscule letter shapes, the inverted-3 form became the basis for lower-case Epsilon in Greek typography during the modern era. The experiments of Coulomb and others showed that the force F between two equal point-like "amounts" of electricity, situated a distance r apart in free space, should be given by a formula that has the form. Despite its pronunciation as mid, in the International Phonetic Alphabet, the Latin epsilon /ɛ/ represents open-mid front unrounded vowel, as in the English word pet /pɛt/. In the uncial script (used for literary papyrus manuscripts in late antiquity and then in early medieval vellum codices), the "lunate" shape ( ) became predominant. The physical constant ε0 (pronounced as "epsilon nought" or "epsilon zero"), commonly called the vacuum permittivity, permittivity of free space or electric constant or the distributed capacitance of the vacuum, is an ideal, (baseline) physical constant, which is the value of the absolute dielectric permittivity of classical vacuum. The idea subsequently developed that it would be better, in situations of spherical geometry, to include a factor 4π in equations like Coulomb's law, and write it in the form: This idea is called "rationalization". Does time-varying magnetic field induce time varying-electric field? The Greek lowercase epsilon ε, the lunate epsilon symbol ϵ, or the Latin lowercase epsilon ɛ (see above) is used in a variety of places: These characters are used only as mathematical symbols. [10][11] This tack glyph was used elsewhere also as a form of "Heta", i.e. The unit of gaussian charge, the statcoulomb, is such that two units, a distance of 1 centimetre apart, repel each other with a force equal to the cgs unit of force, the dyne.

, using either of the common glyphs for the letter epsilon.
