They are more distinctive than the normal alphabet in everyday use and they are less likely to be confused with the language text within mathematical work being written. Today there are advantages to using Greek alphabet symbols. Although later civilisations used their own letters, the use of Greek letters tended to be used down the ages - people tended to use what was already established. They used letters from the Greek alphabet as symbols to represent various variables. The roots of the usage of Greek letters comes from the earliest philosophers like Aristotle, and Diophantus and others. Π, Θ, as well as α, β, θ and the like are widely used and seen seen representing the values or constants for a variety of values. Many letters from the Greek alphabet are used as constants within equations and formulas. There are several reasons why there are many Greek letters that have been adopted into common use for constants in equations.įirst, of course, it is necessary to realise that many of our standard letters are widely used, especially for variables: x, y, z are some common examples, but others are used as well. Why are Greek letters used in mathematical & scientific equations Around 750 BC the Greeks started to adopt the language system from the Phoenicians although there were influences from the Minoans and Mycenaeans that were the other main groups with whom the ancient Greeks had contact.Įssentially the Greek alphabet became the successor to the Phoenician one, and ultimately became the Greek alphabet with its symbols that we use today. One of the major influences for the Greek alphabet were the Phoenicians. How was the Greek alphabet formedĪs everyone knows the Greek alphabet with its characters and symbols dates back many thousands of years.Īlthough the Greek alphabet was widely used within the Greece and its empire, the alphabet and the associated symbols took on influences from much earlier civilisations as well as resulting from influences arising from the trade that took place within the Mediterranean and beyond. Note: The small Greek letter in the alphabet is used except where the notation (cap) is used where the capital version of the Greek letter is used. Scalar potential (cap), magnetic flux, anglesĭielectric flux, phase difference, coordinates, anglesĮlectrical resistance (cap), solid angle, angular velocity Time constant, volume resistivity, time-phase displacement, transmission factor, density Summation (cap), surface charge density, complex propagation constant, electrical conductivity, leakage coefficient, deviation Resistivity, volume charge density, coordinates Permeability, amplification factor (in valves/ vacuum tubes), prefix for the micro multiplier.

The different Greek letters have different meanings or they are used to denote different measures as outlined in the list below. There are very many more examples of Greek letters being used for denoting electrical and electronic units. a resistor has a value of 10Ω and another example is the rho symbol, ρ which is used for resistivity. However the Greek alphabet does have both capital and small versions, and virtually all of the letters are widely used for a variety of different measures.įor example the Omega symbol Ω is used for resistance, e.g. The Greek alphabet only has 24 letters compared to the Latin based script that uses 26. Everything from resistivity, through to impedance, permeance and ratios of circles and much more. Letters including omega, eta, rho, mu and many more are used to denote a whole range of mathematical, scientific and engineering measures. The Greek alphabet is widely used to demote various constants and values within the scientific and technology arenas.
