Designed for people who want to learn or already study mnemonics.The word "mnemonic" is derived from the Ancient Greek word μνημονικός (mnēmonikos), meaning "of memory, or relating to memory" and is related to Mnemosyne ("remembrance"), the name of the goddess of memory in Greek mythology. Both of these words are derived from μνήμη (mnēmē), "remembrance, memory". Mnemonics in antiquity were most often considered in the context of what is today known as the art of memory.
Ancient Greeks and Romans distinguished between two types of memory: the "natural" memory and the "artificial" memory. The former is inborn, and is the one that everyone uses automatically and without thinking. The artificial memory in contrast has to be trained and developed through the learning and practicing of a variety of mnemonic techniques.
The Major System (also called the phonetic number system, phonetic mnemonic system, or Herigone`s mnemonic system) is a mnemonic technique used to aid in memorizing numbers.
The system works by converting numbers into consonant sounds, then into words by adding vowels. The system works on the principle that images can be remembered more easily than numbers.
