Greek Alphabet

One of the first alphabets in the world was used in ancient Greece. It was similar to our current alphabet. In addition to still being used in modern Greek, it has found application in mathematics.

The Greek letters, of which there are 24, have upper and lower case, just like ours. Each also phonetically represents one letter and at the same time has its own name.

Knowing the symbol and name of each Greek letter is extremely useful in mathematics because they occur very often. Among other things, Greek letters denote angles in geometry, also one of the most important constants in mathematics is called π (pi). And the letter Δ (delta) is a generally accepted symbol for difference in mathematics. Greek letters are not only used in mathematic. The World Health Organization used letters of the Greek alphabet to name coronavirus variants: delta and omicron.
