Baltimore Trails: A Guide for Hikers and Mountain Bikers

Book Description

Updating an old favorite, The Baltimore Trail Book, Bryan MacKay has provided a comprehensive and detailed guide to trails on public lands in and around Baltimore. To complete the new work, MacKay walked, cycled, and explored nearly 80 trails in local state, county, and city parks, as well as area watersheds. Discover Hemlock Gorge, a small slice of Appalachia transported into northern Baltimore County, with its timeless peace and ancient gnarled hemlocks; or Black Marsh, with birds soaring overhead or skulking among the vegetation of the pristine freshwater wetlands; or the unique landscape of Soldiers Delight Natural Environment Area, which shelters more than 38 rare plant species.

Baltimore Trails answers the needs of hikers and mountain bikers, offering accurate maps, up-to-date access information, and reliable trail descriptions. From fieldwork conducted entirely in the year 2000, MacKay provides a detailed description, topographic map, and the length, location, and degree of difficulty for each trail. Some trails offer an easy afternoon stroll while others provide a day of rugged hiking or biking. Thumbnail essays offer scenic highlights and discuss typical plants, animals, and local ecology. Praise for MacKay's Hiking, Cycling, and Canoeing in Maryland: A Family Guide"MacKay tells you where to go, what to see and do across the very varied state of Maryland. Well written, the book includes excellent maps, line drawings, and numerous sidebars on the wonders of wandering in the state." -- Paul Sullivan, Fredericksburg Free Lance-Star

Best two stories.......2000-09-17

The best two stories in the collection, in my opinion: You Never Can Tell by Gad Taub, and Idoletry by Yoram Kolerstein.

A worthwhile introduction.......1999-12-18

A mixture -- beautiful, sad, weird. But definitely worthwhile. I was disappointed not to be successful in finding books available by these authors.

buen libro con mal fin así que solo cuatro estrillas.......2005-03-23

Es cuento de una familia méxicana que vienen a EE UU en 1950's a hallar trabajo. Es se dijo a el niño y es en parte una autobiografía. Es un libro corto de 120 paginas y facil a leer. Un buen libro para el joven pero no tiene fin feliz. Quiza el autor usted quiere a leer su segundo libro que es una continuación de este cuento.

Book Description

Interactions between plants and animals are incredibly diverse and complex and span terrestrial, atmospheric and aquatic environments. The last decade has seen the emergence of a vast quantity of data on the subject and there is now a perceived need among both teachers and undergraduate students for a new textbook that incorporates the numerous recent advances made in the field. The book is intended for use by advanced level undergraduate and beginning graduate students, taking related courses in wider ecology degree programmes.

good basic textbook on pollination biology and current debates.......2007-02-28

This is a great foundation book for those interested in pollination biology and systematics. It will teach you the necessary terms for understanding journal papers and give you an overview of the history of the science. This is a VERY easy read.

Book Description

This book is the first part of a modern, two-volume introduction to numerical computation, which strongly emphasizes software aspects. It can serve as a textbook for courses on numerical analysis, particularly for engineers. The book can also be used as a reference book and it includes an extensive bibliography. The author is a well-known specialist in numerical analysis who was involved in the creation of the software package QUADPACK.

Good for reference and self-study.......2001-06-29

This book gives an excellent overview of numerical analysis from both the theoretical and practical points of view. The in-depth discussion given by the author makes this book a welcome addition to the literature on numerical analysis and scientific computation. Fortran 90 is the language of choice for the author in discussing programming implementations of the examples and concepts. There are no exercises in the book, so it would be difficult to use as a textbook or a course in numerical analysis, but it does serve as a useful reference and supplement to such a course.

In chapter 1, the author briefly overviews the strategies and techniques behind scientific modeling and gives many historical examples. A rather short discussion however is given on the testing and validation of models. More should have been said here about this very important phase of the modeling process.

The author introduces the principles behind numerical analysis in chapter 2. He uses the problem of the plane pendulum from elementary physics to motivate the issues involved, such as the accuracy of the mathematical model. The author then classifies numerical problems into four categories, and gives a rigorous discussion of the accuracy of numerical results. This is followed by a discussion of the types of error one would encounter when doing numerics, these being model errors, data errors, algorithm errors, and rounding errors. Data error analysis, which studies the impact on the solution by altering the data on which it is based, is given a fine treatment by the author in terms of functional analysis. He defines the important concepts of absolute and relative condition numbers, and then discusses ill-conditioned problems. The author emphasizes that characterizing a problem as being ill-conditioned depends on the desired level of accuracy. He then gives a fairly complete overview of the validation of numerical computations and numerical software. The author emphasizes the extreme difficulties involved in the accessing of software quality statistically.

Chapter 3 gives an overview of computer hardware and architecture used to perform numerical computations. The author discusses the use of parallelization, pipelining, vector processors, memory hierarchies, caching (the discussion of this is excellent), virtual memory, and interleaving. He also gives a useful discussion of how to quantify numerical software performance, and how to perform an analytical and empirical assessment of hardware performance.

The actual implementation of numerical algorithms is discussed in the next chapter, wherein the author discusses just how numerical data is represented in digital circuits, and how such data is operated on arithmetically. The implementation of floating-point arithmetic, via the IEC/IEEE floating-point standard is discussed. The author addresses well the accuracy issues that arise for problems (such as partial differential equations for example), involving an extremely large number of floating-point operations. In addition, he discusses the use and implementation of multiple-precision arithmetic, with examples given of the ISML, MP, FM, and MPFUN packages for doing this. I have found though that, in addition to some of these packages, high-level symbolic programming languages, such as Mathematica, can be very suitable for heavy-duty number crunching. The discussion of number systems and rounding in this chapter is excellent and well suited for the beginning student in numerical analysis.

Chapter 5 gives begins a discussion of numerical algorithms, and the author discusses the basic notions of algorithms and their complexity characterization via the O-notation. Case studies in matrix multiplication and summation are given to illustrate the contributions of rounding errors and error propagation. This is followed in chapter 6 by a discussion of numerical programs, wherein the author discusses the quality, efficiency, and computational overhead of programs. Performance optimization, via such techniques as loop optimization and blocked memory access, is given a fairly thorough treatment. Again, matrix multiplication is given as a case study for the concepts and techniques discussed by the author.

The software currently available for numerical algorithms is discussed in chapter 7. The IMSL and NAG packages are emphasized, but the author gives a very long list of the packages that are available, both commercially and as freeware.

In chapter 8, the author returns to a discussion of mathematical modeling, wherein approximation techniques are emphasized. After a brief discussion of analytic models, the author moves right into the techniques used to approximate these models, such as discrete and function approximation. More functional analytic techniques are brought in to discuss how to quantify the distance from a model function to the function actually being modeled.

The important technique of interpolation is discussed in chapter 9, and very thoroughly. Polynomial interpolation via Bernstein and Chebyshev polynomials is included, as well as the Horner, Clenshaw, Casteljau algorithms for finding the values of polynomials. Piecewise polynomial interpolation is also treated, as well as spline functions, the latter of which in particular is given a thorough treatment. Multivariate interpolation, along with tensor product interpolation is also discussed at the end of the chapter.

Not coherent!.......2000-03-28

This book is mainly translated into English from German; therefore, the explanation isn't very clear. You spend much time to get the understanding of a subject. It isn't very much related with numerical analysis, instead modelling. Don't expect to find problems about using Numerical Formulas... Another disadvantage of this book is that it is divided into two parts, so, you must spend too much money to get the full content from two parts.

Book Description

Perhaps it was more the fault of Daniel Caldigate the father than of his son John Caldigate, that they two could not live together in comfort in the days of the young man’s early youth.

Download Description

Something more than a month had gone by, and John Caldigate and Mrs. Smith were very close companions. This had not been effected without considerable opposition, partly on the part of Shand, and partly by the ship's inhabitants generally. The inhabitants of the ship were inimical to Mrs. Smith. She was a woman who had no friends; and the very female who had first appeared as a friend was now the readiest to say hard things of her. And Caldigate was a handsome well-mannered young man. By this time all the ladies in the first-class knew very well who he was, and some of them had spoken to him.

Pretty good book.......2003-09-22

John Caldigate is a somewhat weak-willed man where women are concerned, as well as where gambling occurs, so he has managed to bankrupt himself as well as get himself "engaged" to several women through the course of the book, all because he can't say No when he should. Women cause him the greater trouble, but when he eventually returns home to England as a wealthy man (hard work was what made him so) and marries the woman he truly loves, his greatest troubles are now with business associates from his past and his wife's relations. What poses a disaster for himself and his wife (mother of his infant son) is a relationship he had with a "fast" woman, an actress, while he was making his fortune in Australia. She shows up in England, wanting money, and claims that she is actually John's wife. Thus John's marriage is bigamous, his son illegitmate, and his wife downfallen. The extent to which her family interferes, even to kidnapping the wife, is outrageous and dramatic. In fact, most of this book is high drama. It is very entertaining, and it resolves itself nicely, although all John's former "fiancees" do spend much time being thankful that they never married him. There is humor here, and there is tension. A very good read.
