The forms taken by scientific writing help to determine the very nature of science itself. In this closely reasoned study, Charles Bazerman views the changing forms of scientific writing as solutions to rhetorical problems faced by scientists arguing for their findings. Examining such works as the early Philosophical Transactions and Newton's optical writings as well as Physical Review, Bazerman views the changing forms of scientific writing as solutions to rhetorical problems faced by scientists. The rhetoric of science is, Bazerman demonstrates, an embedded part of scientific activity that interacts with other parts of scientific activity, including social structure and empirical experience. This book presents a comprehensive historical account of the rise and development of the genre, and views these forms in relation to empirical experience.

Governments, businesses, and individuals around the world are thinking about what happens after the COVID-19 pandemic. Can we hope to not only ward off another COVID-like disaster but also eliminate all respiratory diseases, including the flu? Bill Gates, one of our greatest and most effective thinkers and activists, believes the answer is yes. The author of the #1 New York Times best seller How to Avoid a Climate Disaster lays out clearly and convincingly what the world should have learned from COVID-19 and what all of us can do to ward off another catastrophe like it. Relying on the shared knowledge of the world’s foremost experts and on his own experience of combating fatal diseases through the Gates Foundation, Gates first helps us understand the science of infectious diseases. Then he shows us how the nations of the world, working in conjunction with one another and with the private sector, how we can prevent a new pandemic from killing millions of people and devastating the global economy. Here is a clarion call—strong, comprehensive, and of the gravest importance.

| WINNER OF THE GAJA CAPITAL BUSINESS BOOK PRIZE 2019 | The nineteenth century was an exciting time of initiative and enterprise around the world. If John D. Rockefeller was creating unimagined wealth in the United States that he would put to the service of the nation, a Parsi family with humble roots was doing the same in India. In 1822, a boy was born in a priestly household in Gujarat's Navsari village. Young Nusserwanji knew early on that his destiny lay beyond his village and decided to head for Bombay to start a business - the first in his family to do so. He had neither higher education nor knowledge of business matters, just a burning passion to carve a path of his own. What Nusserwanji started as a cotton trading venture, his son Jamsetji, born in the same year as Rockefeller, grew into a multifaceted business, turning around sick textile mills, setting up an iron and steel company, envisioning a cutting-edge institute of higher learning, building a world-class hotel, and earning himself the title of the 'Bhishma Pitamah of Indian Industry'. Stewarded ably over the decades by Jamsetji's sons Dorabji and Ratanji, the charismatic and larger-than-life JRD, and thereafter the more business-like Ratan, the Tata group today is a 110-billion-dollar empire. The Tatas is their story. But it is more than just a history of the industrial house; it is an inspiring account of India in the making. It chronicles how each generation of the family invested not only in the expansion of its own business interests but also in nation building. Few know, for instance, that the first hydel power project in the world was conceived of and built by the Tatas. Nor that some radical labour concepts such as eight-hour work shifts were born in India, at the Tata mill in Nagpur. The Tata Cancer Research Centre, the Indian Institute of Science, the Tata Institute of Fundamental Research, as also the national carrier Air India - the family has a long, rich and unrivalled legacy. The Tatas is a tribute to a line of visionaries who have a special place in the hearts and minds of ordinary Indians. Written by seasoned journalist Girish Kuber, this is also the only book that tells the complete Tata story spanning almost two hundred years.

Through ten editions, Fox and McDonald's Introduction to Fluid Mechanics has helped students understand the physical concepts, basic principles, and analysis methods of fluid mechanics. This market-leading textbook provides a balanced, systematic approach to mastering critical concepts with the proven Fox-McDonald solution methodology. In-depth yet accessible chapters present governing equations, clearly state assumptions, and relate mathematical results to corresponding physical behavior. Emphasis is placed on the use of control volumes to support a practical, theoretically-inclusive problem-solving approach to the subject. Each comprehensive chapter includes numerous, easy-to-follow examples that illustrate good solution technique and explain challenging points. A broad range of carefully selected topics describe how to apply the governing equations to various problems, and explain physical concepts to enable students to model real-world fluid flow situations. Topics include flow measurement, dimensional analysis and similitude, flow in pipes, ducts, and open channels, fluid machinery, and more. To enhance student learning, the book incorporates numerous pedagogical features including chapter summaries and learning objectives, end-of-chapter problems, useful equations, and design and open-ended problems that encourage students to apply fluid mechanics principles to the design of devices and systems.
