GLOBAL POTHOLE PROBLEM vs IndustryReview Date: 2007-08-27
Why you should buy two copies...Review Date: 2006-05-15
Hardin made himself politically incorrect amongst "greens" by taking the Malthusian predictions of the movement to their logical conclusion. He was an advocate of tough population control, something that is not the same as birth control; he argued for immigration restrictions, reduced foreign aid and believed the admission of refugees was ecological stupidity. The mainstream of the green movement, if they recognise these issues at all, certainly like to soft pedal on the policy conclusions.
In this volume, that certainly deserves a wider audience, Hardin does not present his policy prescriptions in one big feast, at least not directly. He does sprinkle them lightly through the book, ...but even those who take an opposite viewpoint will not be disappointed by the taste.
He gives us what is essentially a "How To" guide, a book about thinking. He outlines a series of thinking aids, "filters", to help us avoid "folly". The filters are useful not just in dealing with the life and death issues of world population, but in everyday personal and even business problem solving.
Hardin's easy-to-remember tool kit provides us with a broader perspective and thus helps the reader make better decisions.
This is the kind of book you buy an additional copy of to give or lend to friends, because you don't want to lose yours.
Immunization against traps in thinking.Review Date: 2004-05-27
The 3 types of thinking he discusses are: literate, numerical, and ecolate. Literate thinking is exemplified in literature, and in most law. The Bill of Rights and the novel share a similiar view of the world that can be expressed in language.
Numerical thinking is of course arithmatic, but can lead you to a quite different understanding of a situation than literate thinking. Malthus can explain that if a population continues to grow it will ovetake it's food or water supply. Mathematic analysis can tell you exactly when it will happen.
Ecolate, with the same root as 'ecology' was a word unfamiliar to me before reading his book. It can be summed up in the phrase: "And then what?" It is concerned with effects, often unintended, that also occur as a result of any action. Or as Mr. Hardin is more famous for, "You can never do merely one thing."
If there is one weak point it is that it cannot be stressed enough that these three types of thinking are only 3 of many many types. A brief, excellant book, a little off the beaten path from Mr. Hardin's more famous works on population, but there is definite wisdom within.

Unique and monumental researchReview Date: 2001-07-16
Not many projection formulas, but plenty of illustrations, including timelines and original historic maps.
The huge bibliography only hints at the enourmous amount of research and cross-referencing provided by this work. From the viewpoint of map projections, this is *the* ultimate history book.
For its price, an amazingly good book.Review Date: 2003-12-17
The only negative thing I really have to say about Snyder's book is that he tries to do two different things in it. This book is both a history and a survey of map projections, and what is appropriate for a history may not be best for a survey. In particular, it means that Snyder covers the various projections not in a sensible order (grouping similar types together), but chronologically. Projections popularized, say, in the 19th century are all covered in the same section.
I prefer the organization of Kennedy and Kopp's book, and I think the use of color in that book makes for a more attractive book. But my primary rating of a book on map projections is going to be based on three criteria: (1) Does it cover a large variety of different projections? (2) Does it give illustrations of what they look like? and (3) Does it give formulas or other information by which one can actually construct maps on the projections listed? This book ranks much higher than Kennedy and Kopp's on two of these three criteria (the first and last), and does not fall very far short of it on the remnaining one.
Over a hundred projections (actually, close to twice that many) are treated in this book, from familiar ones to novelty projections that never will be used in a serious atlas. And a large proportion of them are illustrated (though not all, and the ones that are do not use color as in the Kennedy & Kopp book) and either have the formulas for plotting them or are described in terms equivalent to giving formulas (By contrast the Kennedy-Kopp book has almost no formulas, and the descriptions do not allow you to produce them).
If you don't want to spend over $50, this is the one map projection book to buy.

"The Black Founding Fathers and Mothers of the Revolutionary Age": An Essential HistoryReview Date: 2006-05-26
Much of the groundwork for these lectures is contained in Nash's 1991 work, _Race and Revolution_, which is an excellent companion to this work because it excerpts the writings and petitions of the black founding fathers: people like Richard Allen, Benjamin Banneker, Prince Hall, and James Forten. Nash reminds readers of an important fact: African Americans were actively involved in the debates of the Revolutionary Period and in the military action as well, fighting on both the American and the British side. In terms of the military involvement, white and black soldiers fought side-by-side in integrated units in the Revolutionary War, a phenonemon which would not re-occur until the Korean War, nearly two hundred years later.
The first chapter "The Black Americans' Revolution" discusses African Americans' participation in the Revolutionary War, a subject that is generally not widely known in the United States. Nash describes the large flight of slaves and freemen to the British-side who offered emancipation in 1775 through Lord Dunmore's Emancipation Proclamation. In contrast, the American forces offered freedom in exchange for one year of military service. For the colonials, wide-spread emancipation was never offered despite the enlightenment rhetoric expressed in the Declaration of Independence and in state constitutions.
Nash begins chapter one by crediting previous historians and, in particular, William C. Nell, whose _Colored Patriots of the American Revolution_ (1855) was the first historical account of black soldiers fighting for the Americans. Nash discusses how Nell, a black school teacher in Boston, focused exclusively on black patriots, de-emphasizing black participation on the British side. The emphasis of Nell's history advanced a political argument for black citizenship and rights in the 1850s, during a period when rights were being retracted in the North.
Chapter two "Could Slavery Have Been Abolished?" looks closely at the contradiction between the Declaration of Independence, with its statements about unalienable rights, and the Constitution, which inscribed legal slavery. Nash makes a convincing case that there was an opportunity for abolition at the beginning of the Republic, which was later sacrificed to short term political interests reflecting the North and Mid-Atlantic states' lack of conviction. Nash criticizes the trend among professional U.S. historians to apologize for the founding fathers' inaction on abolition--the view that historical circumstances did not permit abolition at this time. Nash offers insights about the conflicted views and attitudes of Benjamin Franklin, George Washington, John Adams, James Madison, and Thomas Jefferson on slavery.
The third chapter discusses citizenship and the hardening of racial codes in the 1800s. African Americans' rights and freedoms in the North and Mid-Atlantic states were being curtailed by legislation barring blacks' participation in civic life and foreclosing economic opportunities. Much of the chapter contrasts the views of two Philadelphians: James Forten, a black patriot of the Revolutionary War, and Tench Coxe, a white politician who published pamphlets on race in American in the 1810s and 1820s. Nash threads the discussion of Forten's and Coxe's views throughout the chapter in order to discuss black and white views on race and citizenship in the early 1800s.
A final comment is that this book is very readable in a way that academically-oriented histories often are not. Nash is a diligent scholar and a strong writer with a gift for brevity. As a result, the book can be enjoyed in a few sittings, yielding rewards well worth a reader's time. The footnotes lead in many different directions, and point out new areas of interest for amateur and professional historian alike. There is a wealth of knowledge in this short book.
_The Forgotten Fifth_ can be read profitably by high school, college, and graduate students. It is an important study that will enrich and deepen one's understanding of American history.


The Four Colour Problem,Review Date: 2003-09-22
"Four Colours Suffice" is essentially a chronological history of the Four Colour Conjecture (4CC), the attempts to solve it, the successes and failures, the incremental and fundamental steps forward.
Although Wilson mentions that most of the 20th century used the graph theory perspective to attack the problem, he sticks with the map presentation throughout.
Wilson has a very readable style. He gives the reader a real sense of the key elements of the story, such as Kempe's chain argument, the necessity of pentagons in a minimal criminal (a minimal counterexample to the 4CC), discharging, and reducible and unavoidable configurations. He gives background on the main characters, with excellent photos, and is mostly kind in his evaluation of various individual's contributions. He calls Kempe's flawed proof an excellent proof, and is sincere in that characterization.
The book is very focussed on the 4CC, but does mention related issues such as Heawood's Theorem on the torus, and empires, and Birkhoff's chromatic polynomial. There are no exercises, but there are several proofs, e.g. the five colour theorem.
The controversy over Appel & Haken's proof closes out the book.
I was surprised at the number of people who were nipping at the heels of the 4CC when Appel & Haken announced their solution. There must have been some deflated egos amongst them, but all of the experts supported Appel & Haken when their proof was criticized for its reliance on computers, and its apparent ugliness.
One very minor disappointment is the lack of a bibliography, but this is nullified by the references scattered throughout the endnotes. This is not a math textbook, but is excellent supplementary/bedtime reading. Perhaps it will stimulate a young mathematician to present us with a readable, convincing, and surveyable proof of the 4CC. A Proof From The Book might be too much to hope for, but we can dream.
Four Colours SufficeReview Date: 2002-11-10
"Four Colours Suffice" by Robin Wilson is precisely such a book.
This book marks the 150th anniversary of one of the most famous of all mathematical problems: How many colours are needed to colour in a map so that no two adjacent countries have the same colour?
The problem is famous for two main reasons:
(1) It is very simple to understand but incredibly difficult to solve.
(2) It was eventually solved in 1976 with computer assistance and represents the first major mathematical theorem which continues to resist any attmpet at a solution not requiring computer assitance.
The full story
of how the proof finally came about has to rank as one of the most fascinating stories in the history of mathematics and Robin
Wilson's account is full of interesting anecdotes and lots of humourous asides.
Wilson has gone to immense trouble
to ensure that his book is both accurate and understandable to the novice. All in all a truly rewarding read for anyone with
even a cursory interest in mathematics.

The four color map theorem is easy to understand and hard to prove.
The four color map theorem states that on a plane, which is divided into non-overlapping contiguous regions, the regions can be colored with four colors in such a way that all regions are colored and no two adjacent regions have the same color. In other words you can color any ordinary map with just four colors.
The proof of the four color theorem is very difficult. It is so difficult that the proof took over a century. The search for a proof was so long and became so complex that some mathematicians speculated that it was impossible. The four color served as one of the first real mathematical challenges posed to mathematics undergraduate students.
The statement of the challenge was deceptively simple. Prove that four colors are sufficient. The statement of the problem is so simple that it seems the solution should be equally simple. It is not simple. In 1976 the four-color theorem was finally demonstrated. The authors of the proof are Kenneth Appel and Wolfgang Haken of the University of Illinois.
The book "Four Colors Suffice" is the story of the century long search for the proof. The effort culminated in a computer program. Appel and Haken restated the problem as a collection of 1,936 types of maps. They had a computer program prove each of these 1,936 forms.
The author succeeds in conveying the excitement of the competition in those final months. This book shows the drama of one of the most exciting episodes of modern mathematics.
