Chain Letter Evolution

A history of chain letters based on over 1000 dated examples.
Numerically successful variations are identified and analyzed for their
replicative advantage. English language paper luck chain letters are
the principal topic. Other topics include the Letters from Heaven and
the "Media Chain Letter" which lured celebrity participants in 1990. A bibliography on chain letters and pyramid schemes contains hundreds of sources, including all citations in Chain Letter Evolution. A glossary of specialized terminology used in Chain Letter Evolution is also provided. (Hits 4/2019: 276K)

The Origin of Money Chain Letters

A detailed discussion of the origin and early history of the
"Send-a-Dime" craze of 1935 - the first manifestation of money chain
letters and pyramid schemes. It is shown that the Send-a-Dime letter
was in part modeled on a prior type of luck chain letter. The likely
author of Send-a-Dime was an anonymous woman motivated by charity. This
constitutes a section of Chain Letter Evolution, but can be read
independently.

The Paper Chain Letter Archive

Individual html web pages for over 1000 chain letters arranged by
motivational category and date. Categories include luck chain letters
(600 examples), money, advocacy, "Letters from Heaven", charity, and
exchange. Some unusual items: an anonymous 1917 chain letter giving advice on obtaining conscientious objector status; a 1920 Sinn Fein revolutionary communication; rare scatological parody letters from 1935; a chain letter invitation to a suicide from 1937; apparently the only complete text on the web of the famous Circle of Gold pyramid scheme, this from England, 1982; a libelous Proctor and Gamble boycott alleging satanism from 1986. An annotated index provides easy access to all chain letters in the archive. Chain letter citations in Chain Letter Evolution link to this archive.

The trines - a ternary axiom system

Note:
A detailed exposition, with all proofs, is being prepared.
Links to this should appear here in a month or so. No major errors
have been detected, but no
comments on the "trines" have been received. (10/29/2023)

The "trines" should prove useful because they provide a simple ternary
context to find new theorems and proofs involving familiar fields. They
may also be useful in characterizing new applications. No advanced
methods are used here and results are restricted to a rational venue.

Start
with three distinct "trines", A,B,C, and a
ternary operation, "junction", the junction of trines E,F,G, denoted by
the trine <E,F,G>. Generate all possible expressions using only
A,B,C and junction. Here are four examples of trines: B, <B,A,C>,
<A,A,C>, and <B,C,<A,<C,A,B>,C>>. The trines
are subject to just three equivalence axioms.

1. Generation. The **trines **are: (1) the distinct **primals** A,B,C,** **and (2) the **junction **of any three trines E,F,G, designated <E,F,G>.

Definition. For any trines R,U,V,W the **primal replacement **in **host** R by **members **U,V,W,
designated R(U,V,W), is the trine constructed by replacing every A in R
by U, every B in R by V, and every C in
R by W,
simultaneously. Replacements
of the form A(U,V,V), B(V,U,V), C(V,V,U) are undefined.

In the following three axioms, the host R can be any
trine other than a primal A,B,C. When R is a primal, the replacements
are calculated by the above definition, or they are undefined.

2. Unpairing. R<E,F,F> = F

3. Inversion. R<E,F,R<F,E,X>> = X , E and F distinct.

4. Projection. R<E,F,<X,Y,Z>> = <R<E,F,X>, R<E,F,Y>, R<E,F,Z>>.

Trines can be constructed within the field Q+(d) of all rational expressions in an indeterminate d, **augmented** with plus or minus infinity. If the cross ratio [e,f;g,h] = r holds in Q+(d) I write r[e,f,g] = h. Solving the cross ratio [(e-g)(f-h)] / [(e-h)(f-g)] = r for h gives h = r[e,f,g] = [re(f-g)) + f(g-e)] / [r(f-g) + (g-e)]. Define r[e,e,e] = e, any r, e!=f. If for the ternary
function r[e,f,g] (crossjunction) the
members are fixed, a projective function on r is defined. The
following notation is useful here: a=plus or minus infinity, b=0,
c=1. Function d[x,y,z] generates every element of Q+(d), starting with inputs a, b, c. Then
the correspondences: a~A, 0~B, 1~C, d~D, x+y ~ <<X,B,A>,
A, <A,B,Y>>, -x ~ <B, A,
<A,<X,B,A>,B>>, xy ~ X(A,B,Y), and 1/x ~ X(B,A,C), provide
a bijective
mapping of Q+(d) to equivalence classes of trines. The trine axioms correspond to theorems in Q+(d), proving that the trines are relatively consistent with Q+(d). Defining
primal replacement in Q+(d) the same as for trines,
the theorem r(e,f,g) =
r[e,f,g], is key and may be new.

Further, the augmented field Q+(d) can be constructed within the trines. The correspondences A~a, B~0, C~1, D=<A,B,C> ~ d and R(E,F,G) ~ r[e,f,g], where R~r, E~e, F~f, G~g, assuming X~x and Y~y, define Q+(d) field operations in terms of trines. These are proved to obey the corresponding field axioms for each operation. This construction shows that the trines have been adequately defined and that they can prove any theorem that Q+(d) can. The trines greatly facilitate proofs by induction.

The trines can also construct other fields by adding junctional equivalences to the trine axioms. For example, requiring <A,B,C> = <B,A,C> implies d = -1 and generates the rational numbers. Requiring <A,B,C> = <<B,C,A>,A,B> implies d = i = sqrt(-1) and generates the complex numbers with rational coefficients.If for a mapping P on any trines E,F,G: P(<E,F,G>) = <P(E),P(F),P(G)> P is "projective", and if P is also a bijection on the trines P is called a "projection". Each such mapping corresponds to a projectivity on Q+(d) (synonymously a "homography" or "linear fractional transformation"). The trines can also construct other fields by adding junctional equivalences to the trine axioms. For example, requiring <A,B,C> = <B,A,C> implies d = -1 and generates the rational numbers. Requiring <A,B,C> = <<B,C,A>,A,B> implies d = i = sqrt(-1) and generates the complex numbers with rational coefficients.

Highly Improbable Personally Experienced Repetitions

A list of 30 experiences, by myself or people close to me, that appear
to involve some paranormal phenomenon. Most are seeming precognitive
dreams I have had, some recorded in a journal before an improbable
repetition occurred. Others were repetitions in daily life. Example:

8/17/1975. Huntington Beach, California (recorded in Oxnard). From journal, volume #3, 6 page stapled insert.

"Met a woman, Judy, in Huntington Beach whom I was matched with in a computer dating service. She had a 3 year old boy. Shortly before the child was to go to the baby sitter he began to cry. I went in to his room and got him to talking about his books. He started telling me about his favorite - Donald Duck as a detective. On one page was a picture of 5 or 6 sea animals. He pointed to the picture and named the creatures. But he called a lobster a crab. His mother (on my correcting him) said she was the source of the misidentification.

"Later I was watching television with his mother. Toward the end of the Cher Show people were dressed as food. A man had a crab around his neck. Cher said something very close to: "it should have been a lobster."
