In 1921 a traveling religious man appeared in eastern British Bengal. Soon residents began to identify this half-naked and ash-smeared sannyasi as none other than the Second Kumar of Bhawal--a man believed to have died twelve years earlier, at the age of twenty-six. So began one of the most extraordinary legal cases in Indian history. The case would rivet popular attention for several decades as it unwound in courts from Dhaka and Calcutta to London. This narrative history tells an incredible story replete with courtroom drama, sexual debauchery, family intrigue, and squandered wealth. With a novelist's eye for interesting detail, Partha Chatterjee sifts through evidence found in official archives, popular songs, and backstreet Bangladeshi bookshops. He evaluates the case of the man claiming, with the support of legions of tenants and relatives, to be the long-lost Kumar. And he considers the position of the sannyasi's detractors, including the colonial government and the Kumar's young widow, who resolutely refused to meet the man she denounced as an impostor. Along the way, Chatterjee introduces us to a fascinating range of human character, gleans insights into the nature of human identity, and examines the relation between scientific evidence, legal truth, and cultural practice. The story he tells unfolds alongside decades of Indian history. Its plot is shaped by changing gender and class relations and punctuated by critical historical events, including the onset of World War II, the Bengal famine of 1943, and the Great Calcutta Killings. And by identifying the earliest erosion of colonialism and the growth of nationalist thinking within the organs of colonial power, Chatterjee also gives us a secret history of Indian nationalism.
This book lays out the fundamentals of friction stir welding and processing and builds toward practical perspectives. The authors describe the links between the thermo-mechanical aspects and the microstructural evolution and use of these for the development of the friction stir process as a broader metallurgical tool for microstructural modification and manufacturing. The fundamentals behind the practical aspects of tool design, process parameter selection and weld related defects are discussed. Local microstructural refinement has enabled new concepts of superplastic forming and enhanced low temperature forming. The collection of friction stir based technologies is a versatile set of solid state manufacturing tools.
In the New York Times, critic Teju Cole offered this appreciation of the work of Indian–born photographer Raghubir Singh (1942—1999): "Singh gives us photographs charged with life: not only beautiful experiences or painful scenes but also those in–between moments of drift that make up most of our days." This richly illustrated volume, the first in–depth study of Singh's work, situates it at the intersection of Western modernism and traditional South Asian modes of picturing the world. A major practitioner of color street photography, Singh captured images that demonstrate the diverse culture of India. Raghubir Singh features over 100 of his photographs—in counterpoint with the work of such influences as Henri Cartier–Bresson and Lee Friedlander and with images of traditional South Asian artworks that inspired his practice—providing an extensive overview of the artist's career. With its vibrant plates and insightful essays, this publication brilliantly illustrates Cole's assessment that Singh's work draws "breathtaking coherence out of the chaos of the everyday.
Partha Mitter's book is a pioneering study of the history of modern art on the Indian subcontinent from 1850 to 1922. The author tells the story of Indian art during the Raj, set against the interplay of colonialism and nationalism. The work addresses the tensions and contradictions that attended the advent of European naturalism in India, as part of the imperial design for the westernisation of the elite, and traces the artistic evolution from unquestioning westernisation to the construction of Hindu national identity. Through a wide range of literary and pictorial sources, Art and Nationalism in Colonial India balances the study of colonial cultural institutions and networks with the ideologies of the nationalist and intellectual movements which followed. The result is a book of immense significance, both in the context of South Asian history and in the wider context of art history.
This book starts at an introductory level and leads reader to the most advanced topics in fluorescence imaging and super-resolution techniques that have enabled new developments such as nanobioimaging, multiphoton microscopy, nanometrology and nanosensors. The interdisciplinary subject of fluorescence microscopy and imaging requires complete knowledge of imaging optics and molecular physics. So, this book approaches the subject by introducing optical imaging concepts before going in more depth about advanced imaging systems and their applications. Additionally, molecular orbital theory is the important basis to present molecular physics and gain a complete understanding of light-matter interaction at the geometrical focus. The two disciplines have some overlap since light controls the molecular states of molecules and conversely, molecular states control the emitted light. These two mechanisms together determine essential imaging factors such as, molecular cross-section, Stoke shift, emission and absorption spectra, quantum yield, signal-to-noise ratio, Forster resonance energy transfer (FRET), fluorescence recovery after photobleaching (FRAP) and fluorescence lifetime. These factors form the basis of many fluorescence based devices. The book is organized into two parts. The first part deals with basics of imaging optics and its applications. The advanced part takes care of several imaging techniques and related instrumentation that are developed in the last decade pointing towards far-field diffraction unlimited imaging.

Such knowledge comes through various research activities, practical experience and patient follow up. This book in a unique compilation of all such practical situations where years of experience, to-the-point decisions and lots of background knowledge matters. Decoding Medicine is the definitive guide for anyone involved in patient care or pursuing medicine as their career.
When Siraj, the ruler of Bengal, overran the British settlement of Calcutta in 1756, he allegedly jailed 146 European prisoners overnight in a cramped prison. Of the group, 123 died of suffocation. While this episode was never independently confirmed, the story of "the black hole of Calcutta" was widely circulated and seen by the British public as an atrocity committed by savage colonial subjects. The Black Hole of Empire follows the ever-changing representations of this historical event and founding myth of the British Empire in India, from the eighteenth century to the present. Partha Chatterjee explores how a supposed tragedy paved the ideological foundations for the "civilizing" force of British imperial rule and territorial control in India. Chatterjee takes a close look at the justifications of modern empire by liberal thinkers, international lawyers, and conservative traditionalists, and examines the intellectual and political responses of the colonized, including those of Bengali nationalists. The two sides of empire's entwined history are brought together in the story of the Black Hole memorial: set up in Calcutta in 1760, demolished in 1821, restored by Lord Curzon in 1902, and removed in 1940 to a neglected churchyard. Challenging conventional truisms of imperial history, nationalist scholarship, and liberal visions of globalization, Chatterjee argues that empire is a necessary and continuing part of the history of the modern state.

Globalisation has evolved to become the dominant economic, cultural, environmental and political phenomenon of our time. In economic terms, debates now extend beyond concepts of 'winners and losers', to key questions of how to deal with the problems unleashed by globalisation while preserving its benefits. However, if the benefits of globalisation are fairly shared and the costs properly dealt with, a deeper economic understanding of how globalisation is impacting our economic world is needed. This important book addresses this task, featuring contributions from many of the world's leading economists. Seven key aspects of globalisation are considered: trans-border trade, trans-border movement of people and capital, the emergence of a new international order, the homogenization of economic cultures, technology and institutions, labour market consequences, corporate governance issues, and prospects for a global society. These carefully chosen themes illuminate the complex path that globalisation is following by showing it to be a process consisting of various transitions and subplots, the totality of which is closely examined in this comprehensive and authoritative work. Economics of Globalisation is essential reading for academics, researchers, policy-makers and business professionals.
In this book, the prominent theorist Partha Chatterjee looks at the creative and powerful results of the nationalist imagination in Asia and Africa that are posited not on identity but on difference with the nationalism propagated by the West. Arguing that scholars have been mistaken in equating political nationalism with nationalism as such, he shows how anticolonialist nationalists produced their own domain of sovereignty within colonial society well before beginning their political battle with the imperial power. These nationalists divided their culture into material and spiritual domains, and staked an early claim to the spiritual sphere, represented by religion, caste, women and the family, and peasants. Chatterjee shows how middle-class elites first imagined the nation into being in this spiritual dimension and then readied it for political contest, all the while "normalizing" the aspirations of the various marginal groups that typify the spiritual sphere. While Chatterjee's specific examples are drawn from Indian sources, with a copious use of Bengali language materials, the book is a contribution to the general theoretical discussion on nationalism and the modern state. Examining the paradoxes involved with creating first a uniquely non-Western nation in the spiritual sphere and then a universalist nation-state in the material sphere, the author finds that the search for a postcolonial modernity is necessarily linked with past struggles against modernity.
This landmark report explains the current state of play in relation to biodiversity loss and explores the ways in which we can find a sustainable path to deal with this problem, one that will require us to change how we think, act and measure success"--
The tumultuous last decades of British colonialism in India were catalyzed by more than the work of Mahatma Gandhi and violent conflicts. The concurrent upheavals in Western art driven by the advent of modernism provided Indian artists in post-1920 India a powerful tool of colonial resistance. Distinguished art historian Partha Mitter now explores in this brilliantly illustrated study this lesser known facet of Indian art and history. Taking the 1922 Bauhaus exhibition in Calcutta as the debut of European modernism in India, The Triumph of Modernism probes the intricate interplay of Western modernism and Indian nationalism in the evolution of colonial-era Indian art. Mitter casts his gaze across a myriad of issues, including the emergence of a feminine voice in Indian art, the decline of “oriental art,” and the rise of naturalism and modernism in the 1920s. Nationalist politics also played a large role, from the struggle of artists in reconciling Indian nationalism with imperial patronage of the arts to the relationship between primitivism and modernism in Indian art. An engagingly written study anchored by 150 lush reproductions, The Triumph of Modernism will be essential reading for scholars of art, British studies, and Indian history.

The biomedical sciences have recently undergone revolutionary change, due to the ability to digitize and store large data sets. In neuroscience, the data sources include measurements of neural activity measured using electrode arrays, EEG and MEG, brain imaging data from PET, fMRI, and optical imaging methods. Analysis, visualization, and management of these time series data sets is a growing field of research that has become increasingly important both for experimentalists and theorists interested in brain function. Written by investigators who have played an important role in developing the subject and in its pedagogical exposition, the current volume addresses the need for a textbook in this interdisciplinary area. The book is written for a broad spectrum of readers ranging from physical scientists, mathematicians, and statisticians wishing to educate themselves about neuroscience, to biologists who would like to learn time series analysis methods in particular and refresh their mathematical and statistical knowledge in general, through self-pedagogy. It may also be used as a supplement for a quantitative course in neurobiology or as a textbook for instruction on neural signal processing. The first part of the book contains a set of essays meant to provide conceptual background which are not technical and shall be generally accessible. Salient features include the adoption of an active perspective of the nervous system, an emphasis on function, and a brief survey of different theoretical accounts in neuroscience. The second part is the longest in the book, and contains a refresher course in mathematics and statistics leading up to time series analysis techniques. The third part contains applications of data analysis techniques to the range of data sources indicated above (also available as part of the Chronux data analysis platform from http://chronux.org), and the fourth part contains special topics.
Partha Chatterjee, a pioneering theorist known for his disciplinary range, builds on his theory of "political society" and reinforces its salience to contemporary political debate. Dexterously incorporating the concerns of South Asian studies, postcolonialism, the social sciences, and the humanities, Chatterjee broadly critiques the past three hundred years of western political theory to ask, Can democracy be brought into being, or even fought for, in the image of Western democracy as it exists today? Using the example of postcolonial societies and their political evolution, particularly communities within India, Chatterjee undermines the certainty of liberal democratic theory in favor of a realist view of its achievements and limitations. Rather than push an alternative theory, Chatterjee works solely within the realm of critique, proving political difference is not always evidence of philosophical and cultural backwardness outside of the West. Resisting all prejudices and preformed judgments, he deploys his trademark, genre-bending, provocative analysis to upend the assumptions of postcolonial studies, comparative history, and the common claims of contemporary politics.
