Review of "Decades of Doubt," by Eric Wilson and John Turner



Review of

Decades of Doubt, by Eric Wilson and John Turner ISBN 9781943275366

Four out of five stars

 This is a book about the murder of a teenage boy in the late sixties where the investigation was generally dormant but then suddenly revived and a man was charged with the murder and the trial took place in 2013. What is odd about the case is that there was no new hard evidence in the sense of DNA, blood or other findings due to the subsequent advance of forensic science. The sudden change was due to the altered testimony of one of the boys that knew the victim. The case received national attention as a CBS 48 Hours Murder Mystery.
 Eric Wilson was the lead defense attorney in the trial and this book is generally written in the form of a third person narrative. However, there are sections clearly labeled as “Ex Parte” where the presentation is a narrative by Wilson.
 The presentation style can be summed up by two brief passages, the first is from the back cover that is in essence repeated in the text.
“A handsome, high-profile and tenacious defense attorney (Wilson).”
The second is from page 362.
“Eric’s decision to have Dr. Tom Andrew testify last was a brilliant one.”
Insignificant if written by a true third party, but not when the author is the one being described.
 The sections of the trial are generally laudatory of Wilson, recitations of his effectiveness as an attorney. There is little in the way of hints at something Wilson did wrong, not even in the slightest.  When another man is tried for the same murder and convicted based on the same evidence, the explanations are that the defense attorney was simply not as good as Wilson.
  As you read the description of the case and the trial, the impression is that this was a case of the zeal of a detective and a prosecutor in their goal of solving a cold case getting ahead of the evidence. There was nothing new, only 40-year-old memories of a traumatic event. With the exception of eidetic memories, recollections fade over such lengthy intervals and some of the earlier investigators were themselves deceased. The relative ease of the not guilty verdict is understandable.
 There are some looks inside the legal system in this book that are illuminating. The tactics of the prosecuting and defense attorneys in trying to emotionally sway the members of the jury are right out of dramatizations of legal proceedings. Investigators focusing on what they believe and not following other promising leads is also a reminder of how things can go wrong.

Nonamorphic Numbers Revisited

Charles Ashbacher
cashbacher@yahoo.com

Abstract
 In volume 20, number 2 of Journal of Recreational Mathematics, Charles W. Trigg defined a nonamorphic number to be a nonagonal number N(n) = n(7n – 5) / 2 that terminates in n. For example, N(25) = 2125 and N(625) = 1365625. The purpose of this paper is to report the results of a greater search for nonamorphic numbers.

Octamorphic Numbers Revisited

Charles Ashbacher
cashbacher@yahoo.com
Abstract
 In volume 19, number 2 of Journal of Recreational Mathematics, Charles W. Trigg defined an octamorphic number to be an octagonal number E(n) = n(3n – 2) that terminates in n. For example, E(25) = 1825 and E(625) = 1170625. The purpose of this paper is to report the results of a greater search for octamorphic numbers.
Pentamorphic Numbers Revisited

cashbacher@yahoo.com

Abstract
 In volume 16, number 1 of Journal of Recreational Mathematics, Charles W. Trigg defined a pentamorphic number to be a pentagonal number P(n) = n(3n – 1) / 2 that terminates in n. For example, P(25) = 925 and P(625) = 585625. The purpose of this paper is to report the results of a greater search for pentamorphic numbers.


African Horizons: A Math Enrichment Experience in Kenya

Abstract
 The author’s most recent teaching experience in Africa was one year of teaching mathematics at Daystar University.  This paper describes challenges with the classroom culture at that institution and the author’s attempt to motivate students through the use of mathematical activity of a more recreational nature.

The Life-Time of the World

Abstract
 The legend is that, at the creation of the world, there was a Tower of Hanoi with three poles and 64 discs, in a temple. The priests there are in the process of transferring the tower from one pole to another, in minimum number of moves, where each move transfers one disc from one pole to another under the “divine rule” that no disc can ever be placed on top of a smaller one. As soon as the task of the priests would be completed, the world would come to an end. This paper examines the different cases when a single relaxation of the “divine rule” is allowed.

Keywords. The Tower of Hanoi, divine rule, the life-time of the world.

Palindromic Numbers and Iterations of the Pseudo-Smarandache Function

Charles Ashbacher

Abstract

 For n ≥ 1, the Pseudo-Smarandache function Z(n) is the smallest integer m such that n evenly divides  1 + 2 + 3 + . . . + m. In this paper, some iterations of this function on palindromes that yield palindromes are demonstrated.

 This paper was originally published in Proceedings of the First International Conference on Smarandache Type Notions in Number Theory, American Research Press, 1997.

Divisibility and Periodicity Patterns and Palatable Number Tricks in the Jacobsthal Sequence

Jay L. Schiffman
Rowan University
schiffman@rowan.edu

Abstract
The Jacobsthal sequence is a Fibonacci-like sequence defined as follows:

            J0 = 0, J1 = 1 and Jn = Jn-1 + 2 * Jn-2 for n  ≥ 2.

The initial few terms of this sequence are 0, 1, 1, 3, 5, 11, 21, 43, 85,…. This paper will explore divisibility and periodicity patterns, early primes and palatable number tricks in this sequence.

Smarandache Bisymmetric Geometric Determinant Sequence

APU, 1–1 Jumonjibaru, Beppu-shi 875–8577, Oita-ken, Japan


Abstract
In this paper, the concept of Smarandache bisymmetric geometric determinant sequence has been introduced. An explicit form of the nth term is given.

Key Words  Smarandache bisymmetric geometric determinant sequence, nth term of the sequence.

The NFL Draft, 2002-2014: Winners, Losers, and  a
New Draft Trade Value Chart

Paul M. Sommers
Middlebury College

Abstract
 Data on career approximate value (AV) of all National Football League (NFL) players drafted between 2002 and 2014 show how career AV varies by round, position, and team.  Career AVs of the drafted players are then used to assess winners and losers in each of the thirteen annual NFL drafts.  Finally, regression analysis is employed to assign a trade value to each of the 224 players picked in a 32-team, seven-round draft.  These values are used to evaluate the draft day trades in 2010 and which teams stand to benefit from trades up to and during the 2015 NFL draft.
