Both upper case M and lower case m each have three points on the baseline and look like the numeral 3 on its side.įour ends with r (and /r/ in rhotic accents). Upper case N and lower case n each have two vertical strokes and two points on the baseline. The alveolar stops /t/ and /d/ form a voiceless and voiced pair, as do the similar-sounding dental fricatives /θ/ and /ð/, though some variant systems may omit the latter pair. Upper case T and D, as well as lower case t and d have one vertical stroke each, as with the numeral 1. The alveolar fricatives /s/ and /z/ form a voiceless and voiced pair. Upper case S and Z, as well as lower case s and z, have zero vertical strokes each, as with the numeral 0. These can be used as "fillers" to make sensible words from the resulting consonant sequences. For example, the letters C in "cat", "Cynthia", and "cello" each have different values in the system – 7, 0, and 6, respectively.) Vowels, semivowels and the consonant /h/ are ignored. (In other words, the link is to the sound, not the letter. The system Įach numeral is associated with one or more consonants.

In this, Gardner traces the history of the system back to Pierre Hérigone and Richard Grey with uses by Lewis Carroll and Gottfried Wilhelm Leibniz. One notable explanation of this system was given in Martin Gardner's book The First Scientific American Book of Mathematical Puzzles and Diversions (just Mathematical Puzzles and Diversions in the UK edition), which has since been republished in The New Martin Gardner Mathematical Library as Hexaflexagons, Probability Paradoxes, and the Tower of Hanoi. The system works on the principle that images can be remembered more easily than numbers. The system works by converting numbers into consonants, then into words by adding vowels.


Since we know of only 2 actual complete sets still existing after fifty-eight years, this is our electronic preservation of the history of the development of hypnotism as a profession in America since WWII.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.
