I ?rst heard of k·p in a course on semiconductor physics taught by my thesis adviser William Paul at Harvard in the fall of 1956. He presented the k·p Hamiltonian as a semiempirical theoretical tool which had become rather useful for the interpre- tion of the cyclotron resonance experiments, as reported by Dresselhaus, Kip and Kittel. This perturbation technique had already been succinctly discussed by Sho- ley in a now almost forgotten 1950 Physical Review publication. In 1958 Harvey Brooks, who had returned to Harvard as Dean of the Division of Engineering and Applied Physics in which I was enrolled, gave a lecture on the capabilities of the k·p technique to predict and ?t non-parabolicities of band extrema in semiconductors. He had just visited the General Electric Labs in Schenectady and had discussed with Evan Kane the latter’s recent work on the non-parabolicity of band extrema in semiconductors, in particular InSb. I was very impressed by Dean Brooks’s talk as an application of quantum mechanics to current real world problems. During my thesis work I had performed a number of optical measurements which were asking for theoretical interpretation, among them the dependence of effective masses of semiconductors on temperature and carrier concentration. Although my theoretical ability was rather limited, with the help of Paul and Brooks I was able to realize the capabilities of the k·p method for interpreting my data in a simple way.

THE SUNDAY TIMES BESTSELLER 'Outrageous, audacious, jaw-dropping' SUNDAY TIMES 'An essential read' DAILY MAIL 'Utterly captivating' DAILY TELEGRAPH 'Hugely entertaining' GUARDIAN The fascinating life story of professional cricketer Kevin Pietersen, MBE, from his childhood in South Africa to his experiences as one of the leading lights in the world of international cricket. Kevin was dropped from the England squad in February 2014, seemingly calling time on an international career that began nearly ten years earlier. The decision puzzled many observers - although the England team had failed miserably in the Ashes tour of 2013-14, Kevin was the tourists' leading run scorer across the series, and he remains the country's highest run scorer of all time across all formats of the game. Kevin reveals all in his autobiography, telling the stories behind the many other highs and lows of his incredible career. Giving readers the full story of his life, from his childhood in South Africa to his experiences as one of the leading lights in the world of international cricket, KP is an autobiography that entertains and fascinates readers in equal measure.

This book constitutes refereed proceedings of the First International Workshop on Algorithmic Bias in Search and Recommendation, BIAS 2020, held in April, 2020. Due to the COVID-19 pandemic BIAS 2020 was held virtually. The 10 full papers and 7 short papers were carefully reviewed and seleced from 44 submissions. The papers cover topics that go from search and recommendation in online dating, education, and social media, over the impact ofgender bias in word embeddings, to tools that allow to explore bias and fairnesson the Web.

Sindhi nationalism is one of the oldest yet least studied cases of identity politics in Pakistan. Ethnic discontent appeared in Sindh in opposition to the rule of the Bombay presidency; to the onslaught of Punjabi settlers in the wake of canal irrigation; and, most decisively, to the arrival of millions of Muhajirs (Urdu-speaking migrants) after Partition. Under Zulfikar Ali Bhutto, Benazir Bhutto and Asif Zardari, the Pakistan People's Party has upheld the Sindhi nationalist cause, even while playing the game of federalist politics. On the other side for half a century have been hardcore Sindhi nationalist groups, led by Marxists, provincial autonomists, landlord pirs and liberal intelligentsia in pursuit of ethnic outbidding. This book narrates the story of the Bhutto dynasty, the Muhajir factor, nationalist ideologues, factional feuds amongst landed elites, and the role of violence as a maker and shaper of Sindhi nationalism. Moreover, it examines the role of the PPP as an ethnic entrepreneur through an analysis of its politics within the electoral arena and beyond. Bringing together extensive fieldwork and comparative studies of ethno-nationalism, both within and outside Pakistan, Asma Faiz uncovers the fascinating world of Sindhi nationalism.
