The OpenType font format has the feature tag "mgrk" ("Mathematical Greek") to identify a glyph as representing a Greek letter to be used in mathematical (as opposed to Greek language) contexts. The table below shows a comparison of Greek letters rendered in TeX and HTML. The font used in the TeX rendering is an italic style.
mass density usually simply called density kilogram per cubic meter (kg/m 3) volume charge density: coulomb per cubic meter (C/m 3) resistivity: ohm meter (Ω⋅m) sigma: summation operator area charge density: coulomb per square meter (C/m 2) electrical conductivity: siemens per meter (S/m) normal stress: pascal (Pa)
The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: [ 1 ] ρ = m V , {\displaystyle \rho ={\frac {m}{V}},} where ρ is the density, m is the mass, and V is the volume.
Some quantities are known as several different names such as the magnetic B-field which is known as the magnetic flux density, the magnetic induction or simply as the magnetic field depending on the context. Similarly, surface tension can be denoted by either σ, γ or T. The table usually lists only one name and symbol that is most commonly used.
The Greek alphabet was the model for various others: [8] Most of the Iron Age alphabets of Asia Minor were adopted around the same time, as the early Greek alphabet was adopted from the Phoenician. The Lydian and Carian alphabets are generally believed to derive from the Greek alphabet, although it is not clear which variant is the direct ancestor.
The oldest known image of Dionysus accompanied by his name is found on a dinos by the Attic potter Sophilos around 570 BC and is located in the British Museum. [34] By the seventh century, iconography found on pottery shows that Dionysus was already worshiped as more than just a god associated with wine.
The second-youngest Olympian, just older than Dionysus. His symbols include the caduceus (staff entwined with two snakes), winged sandals and cap, stork, and tortoise (whose shell he used to invent the lyre). Most lists of the "twelve Olympians" consist of the above eleven plus either Hestia or Dionysus: Hestia: Vesta
In addition, Dionysus is known as Lyaeus ("he who unties") as a god of relaxation and freedom from worry and as Oeneus, he is the god of the wine press. In the Greek pantheon, Dionysus (along with Zeus) absorbs the role of Sabazios, a Phrygian deity. In the Roman pantheon, Sabazius became an alternate name for Bacchus. [14]
