About the BookA SEARING ACCOUNT OF 1984, PACKED WITH STORIES AND MEMORIES.'I want sukh, peace, ' said Shanti. She had watched her three sons, one of them an infant, and husband torched alive by marauding mobs. The sixty-five-year-old Sikh woman from a west Delhi slum said that the police had inserted a stick inside her.The distraught man spoke a single sentence but repeated it twice in chaste Punjabi: 'Please give me a turban. I want nothing else.'In the aftermath of Indira Gandhi's assassination in 1984, 2,733 Sikhs were burnt, stabbed, beaten and otherwise hunted to their deaths across Delhi. Many of them were children. Several hundreds were killed elsewhere in the country. Nilanjan Mukhopadhyay uses personal histories to expose the truth of a state-sponsored riot: the thousands of lives that were destroyed, the cruel apathy of subsequent governments, the lack of reparations, the denial of justice. Poignant and raw, Sikhs: The Untold Agony of 1984 lays bare the innards of one of the most shameful episodes of sectarian violence in post-Independence India.About the AuthorNilanjan Mukhopadhyay embarked on a career in journalism in the early 1980s and is best known for his reportage and analysis of the rise and growth of Hindu organisations, their politics and agitations. He is among the first journalists to track the emergence of the Ram Janmabhoomi-Babri Masjid conflict from the late 1980s. He has followed, and written about, the political and electoral emergence of the BJP and its allies from that period.He is the author of The Demolition: India at the Crossroads (1994), one of the first books on the Ayodhya discord and the rise of Hindutva. He is also the author of Narendra Modi: The Man, the Times (2013), The RSS: Icons of the Indian Right (2019) and The Demolition and the Verdict: Ayodhya and the Project to Reconfigure India (2021). He is a regular columnist in, and contributor to, several leading newspapers and web portals, and a well-known commentator and host on Indian television news and video channels. An unabashed college dropout, he lives in India's National Capital Region.

L'optique de polarisation est uniquement basée sur le phénomène de biréfringence. Les matériaux qui présentent une biréfringence naturelle trouvent souvent des applications dans les dispositifs de polarisation, bien que ce phénomène puisse être induit extérieurement dans certains matériaux. Cependant, leurs performances dépendent de la longueur d'onde, ce que l'on appelle la chromaticité. Or, dans de nombreuses applications, les dispositifs achromatiques sont demandés. Par conséquent, l'élimination de cette dépendance chromatique est un domaine intéressant pour les chercheurs dans ce domaine. Des matériaux tels que le quartz cristallin, le MgF2, etc., sont largement utilisés pour concevoir des retardateurs de phase achromatiques qui fournissent une différence de phase constante entre deux composantes orthogonales de la lumière sur une large gamme de longueurs d'onde. Dans ce livre, des réseaux biréfringents basés sur des plaques d'onde des mêmes matériaux, ainsi que de nouvelles combinaisons de différents matériaux biréfringents ont été introduits pour obtenir un comportement superachromatique sur de larges régions de longueur d'onde. En outre, un filtre optique doté d'un nouveau réseau biréfringent est également discuté. Il présente une caractéristique de transmission à bande passante étroite dans le domaine visible pour des applications astronomiques.

A ótica de polarização baseia-se exclusivamente no fenómeno chamado birrefringência. Os materiais que exibem birrefringência naturalmente encontram frequentemente aplicações em dispositivos de polarização, embora este fenómeno possa ser induzido externamente em alguns materiais. No entanto, o seu desempenho depende do comprimento de onda, o que é designado por cromaticidade. Mas em muitas aplicações, os dispositivos acromáticos são procurados. Por conseguinte, a eliminação desta dependência cromática tem sido um campo interessante para os investigadores neste domínio. Materiais como o quartzo cristalino, o MgF2, etc., estão a ser amplamente utilizados para conceber retardadores de fase acromáticos que fornecem uma diferença de fase constante entre dois componentes ortogonais da luz numa vasta gama de comprimentos de onda. Neste livro, foi introduzida uma rede birrefringente baseada em placas de onda dos mesmos materiais, bem como novas combinações de diferentes materiais birrefringentes, para obter um comportamento superacromático em amplas regiões de comprimento de onda. Além disso, é também discutido um filtro ótico com uma nova rede birrefringente que apresenta uma caraterística de transmissão de banda estreita na gama do visível para aplicações astronómicas.

L'ottica di polarizzazione si basa esclusivamente sul fenomeno della birifrangenza. I materiali che presentano naturalmente la birifrangenza trovano spesso applicazione nei dispositivi di polarizzazione, anche se questo fenomeno può essere indotto esternamente in alcuni materiali. Tuttavia, le loro prestazioni dipendono dalla lunghezza d'onda, definita cromaticità. In molte applicazioni, però, sono richiesti dispositivi acromatici. Pertanto, l'eliminazione di questa dipendenza cromatica è un campo interessante per i ricercatori in questo settore. Materiali come il quarzo cristallino, l'MgF2 ecc. sono ampiamente utilizzati per la progettazione di ritardatori di fase acromatici che forniscono una differenza di fase costante tra due componenti ortogonali della luce in un'ampia gamma di lunghezze d'onda. In questo libro, sono state introdotte reti birifrangenti basate su piastre d'onda degli stessi materiali e nuove combinazioni di materiali birifrangenti diversi per ottenere un comportamento superacromatico in ampie regioni di lunghezza d'onda. Inoltre, viene discusso un filtro ottico con una nuova rete birifrangente che presenta una caratteristica di trasmissione a banda stretta nel campo del visibile per applicazioni astronomiche.

Die Polarisationsoptik beruht ausschließlich auf dem Phänomen der Doppelbrechung. Materialien, die von Natur aus doppelbrechend sind, werden häufig für polarisierende Geräte verwendet, obwohl dieses Phänomen bei einigen Materialien auch von außen herbeigeführt werden kann. Ihre Leistung ist jedoch wellenlängenabhängig, was als Chromatizität bezeichnet wird. In vielen Anwendungen sind jedoch achromatische Geräte gefragt. Daher ist die Beseitigung dieser chromatischen Abhängigkeit ein interessantes Forschungsgebiet. Materialien wie kristalliner Quarz, MgF2 usw. werden häufig für die Entwicklung achromatischer Phasenverzögerer verwendet, die eine konstante Phasendifferenz zwischen zwei orthogonalen Lichtkomponenten über einen großen Wellenlängenbereich hinweg gewährleisten. In diesem Buch werden doppelbrechende Netzwerke auf der Grundlage von Wellenplatten aus denselben Materialien sowie neuartige Kombinationen verschiedener doppelbrechender Materialien vorgestellt, um ein superachromatisches Verhalten über weite Wellenlängenbereiche zu erreichen. Darüber hinaus wird ein optischer Filter mit einem neuen doppelbrechenden Netzwerk erörtert, der eine enge Bandpass-Transmissionscharakteristik im sichtbaren Bereich für astronomische Anwendungen aufweist.

THE FIRST AUTHORITATIVE BIOGRAPHY OF INDIA'S CURRENT PRIME MINISTEROn 26 December 2012, Narendra Modi was sworn in as the Chief Minister of Gujarat for the fourth time, to extend his record tenure in office. Even then, his name prompted extremes of hate-filled anger or outright adulation. Since then, despite polarising Gujarat and India in more ways than one, he continues to do what it takes to survive in a democracy: win elections.Written by veteran journalist and writer, Nilanjan Mukhopadhyay, after several in-depth interviews, meticulous research and extensive travel through Gujarat, this book reveals hitherto unknown aspects of Narendra Modi's psyche: as a six year-old boy selling tea to help out his father and distributing badges and raising slogans at the behest of a local political leader, abandoning his family and wife in search of his definition of truth, being initiated into the RSS as a fledgling who ran errands for his seniors, and finally, his meteoric rise after 2002.Narendra Modi: The Man, The Times is the definitive biography of a man who may have challenged the basic principles of a sovereign, secular nation, but emerged as an undisputed and larger-than-life leader.
