Currents and Mesons

J. J. Sakurai

University of Chicago Press, 1969

Current and Mesons is the most recent publication in the Chicago Lectures in Physics series. The book presents Professor Sakurai's introduction to a new field of elementary particle physics which has become increasingly important in the past few years. It is based on a course given to his advanced graduate students in theoretical high-energy physics at the University of Chicago.

The author begins with a brief review of SU (3). The major topics then treated are the divergence condition and current commutation relations, vector meson universality, PCAC and the Goldberger-Treiman relation, soft pion processes, and asymptotic symmetries and spectral-function sum rules. The book concludes with a discussion of notation and of normalization convention.

Professor Sakurai's work deals with topics on which much of current discussion on the theory of elementary particles is focused. The material is designed for the advanced student who is seriously interested in doing original work, and as such provides a much needed introduction to the present literature in the field.

Custodians of the Land

Ecology and Culture in the History of Tanzania

Gregory H. Maddox

Ohio University Press, 1995

Farming and pastoral societies inhabit ever-changing environments. This relationship between environment and rural culture, politics and economy in Tanzania is the subject of this volume which will be valuable in reopening debates on Tanzanian history.

In his conclusion, Isaria N. Kimambo, a founding father of Tanzanian history, reflects on the efforts of successive historians to strike a balance between external causes of change and local initiative in their interpretations of Tanzanian history.

He shows that nationalist and Marxist historians of Tanzanian history, understandably preoccupied through the first quarter-century of the country's post-colonial history with the impact of imperialism and capitalism on East Africa, tended to overlook the initiatives taken by rural societies to transform themselves.

Yet there is good reason for historians to think about the causes of change and innovation in the rural communities of Tanzania, because farming and pastoral people have constantly changed as they adjusted to shifting environmental conditions.

Cycling Science

How Rider and Machine Work Together

Max Glaskin

University of Chicago Press, 2012

Every July hundreds of thousands flock to the Champs-Élysées in Paris—and millions more to their televisions and computers—to witness the dramatic conclusion of the grueling three weeks of the Tour de France. There is no better measure of the worldwide love of the bicycle. But of the 1.2 billion cyclists traversing the world’s roadways and trails, few of us take the time to consider the science behind the sport. The simple process of getting about on two wheels brings us in touch with a wealth of fascinating science, and here journalist Max Glaskin investigates the scientific wonders that keep cyclists in their saddles.
 
Cycling Science tours readers through a wide variety of topics, from tire rolling resistance and the difference between yield strength and ultimate strength, to the importance of aerodynamics and the impact that shaved legs have on speed. Each chapter explores a different subject—fundamentals, strength and stability, materials, power, aerodynamics, and the human factor—and is organized around a series of questions: What is the ideal frame shape? What is the biggest source of drag? What keeps a bicycle from falling over? How much power can a cyclist produce? Which muscles does cycling use? Each question is examined with the aid of explanatory diagrams and illustrations, and the book can be used to search for particular topics, or read through for a comprehensive overview of how machine and rider work together.
 
Athletes have much to gain from understanding the science of their sports, and Cycling Science will be a must-read for cyclists of all stripes—professionals, recreational riders, and anyone seeking to enhance their enjoyment of cycling.

Cyperaceae

Sedges

Robert H. Mohlenbrock

Southern Illinois University Press, 2005

The first in a series of four illustrated guides to identifying aquatic and standing water plants in the central Midwest, this convenient reference volume covers the 183 species of Cyperaceae. Robert H. Mohlenbrock includes three types of plants: submergents, those that spend their entire lives with their vegetative parts either completely submerged or at least floating on the water’s surface; emergents, which are typically rooted underwater with their vegetative parts standing out of water; and a third category of plants that live most of their lives out of water, but which may live in water at least three months a year.


Mohlenbrock provides descriptions, illustrations, and ways to identify any plant in the sedge family (Cyperaceae) in the states of Kentucky (except for the Cumberland region), Ohio, Indiana, Illinois, Iowa, Missouri, Kansas, and Nebraska. With taxa arranged alphabetically, the volume is well organized and easy to use. In addition, basic synonymy, description, distribution, comments, and line drawings that show the habits and distinguishing features for each plant. Habitat and nomenclatural notes are also listed, as are the official wetland designations given by the U.S. Fish and Wildlife Service.


Cyperaceae is a useful standard reference for state and federal employees who deal with aquatic and wetland plants and environmental conservation and mitigation issues and an essential guide for students and instructors in college and university courses where the identification of aquatic and wetland plants is emphasized.
