Hindquarters, for example, translates unambiguously to 2174140 (/n/-/d/-/k/-/r/-/t/-/r/-/z/), which amounts to a twelve-letter word encoded by seven digits in seven letters, and can be easily visualized.
For most people it would be easier to remember 3.1415927 (an approximation of the mathematical constant pi) as: Short term visual memory of imagined scenes allows large numbers of digits to be memorized with ease.
Longer-term memory may require the formulation of more object-related mnemonics with greater logical connection, perhaps forming grammatical sentences that apply to the matter rather than just strings of images.
One would typically make up multiple words, preferably a sentence, or an ordered sequence of images featuring the owner of the number.
A different memory system, the method of loci, was taught to schoolchildren for centuries, at least until 1584, "when Puritan reformers declared it unholy for encouraging bizarre and irreverent images.
In 1808 Gregor von Feinaigle introduced the improvement of representing the digits by consonants (but reversed the values of 8 and 9 compared to those listed above).
[17] In 1843, Carl Otto Reventlow (1817–1873) published a mnemonics textbook on a method similar to Paris' and traveled throughout Germany promoting it.
In 1844 Francis Fauvel Gouraud (1808–1847) delivered a series of lectures introducing his mnemonic system which was based on Aimé Paris' version.
Because he was charging inordinate sums of money for a system which had obviously existed before, George S. Fellows published "Loisette" exposed (1888)[19] and included all the material of Larrowe's course which he determined not to be under copyright.
[21][22][23] Following the revelation that he had not originated the system, Larrowe self-published his material under the pseudonym Dr. Antoine Loisette in 1895 and 1896 and it was later re-published by Funk & Wagnalls in 1899.
[26] Poehlmann eventually moved back to Germany around 1910 where he continued offering his memory courses and training apparently with a focus on language learning.
Fürst later practiced criminal law in Frankfort in pre-Hitler Germany before fleeing, as a Jew, to Prague where he taught at Masaryk University until emigrating to New York in 1939.
The system described in this article would be re-popularized after 1957 and through the 1980s in several books by Harry Lorayne, a magician and best selling contemporary author on memory.
[28] This phonetic system had another resurgence in the 1990s thanks to the late night infomercials of Kevin Trudeau who sold a series of tapes called Mega Memory.
This pre-memorisation and practice at forming images reduces the time required to think up a good imaginary object while creating a strong memorable impression of it.
It might be possible for some people to construct and then learn a string of 53 or more items which you have substituted for the elements and then to recall them one by one, counting them off as you go, but it would be a great deal easier and less laborious/tedious to directly associate element 53 with, for example, a lime (a suitable mnemonic for 53) recalling some prior imagining of yours regarding a mishap where lime juice gets into one's eye - "eye" sounding like "I", the symbol for Iodine.
