Generalized probabilistic theories (GPTs) allow us to write quantum theory in a purely operational language and enable us to formulate other, vastly different theories. As it turns out, there is no canonical way to integrate the notion of subsystems within the framework of convex operational theories. Sections can be seen as generalization of subsystems and describe situations where not all possible observables can be implemented. Jonathan Steinberg discusses the mathematical foundations of GPTs using the language of Archimedean order unit spaces and investigates the algebraic nature of sections. This includes an analysis of the category theoretic structure and the transformation properties of the state space. Since the Hilbert space formulation of quantum mechanics uses tensor products to describe subsystems, he shows how one can interpret the tensor product as a special type of a section. In addition he applies this concept to quantum theory and compares it with the formulation in the algebraic approach. Afterwards he gives a complete characterization of low dimensional sections of arbitrary quantum systems using the theory of matrix pencils.

This riveting, New York Times bestselling biography illuminates the life of the statesman who unified Germany but who also embodied everything brutal and ruthless about Prussian culture. Jonathan Steinberg draws heavily on contemporary writings, allowing Bismarck's friends and foes to tell the story of this brilliant yet diabolical genius.

An insight into the ambivalence in the relationship between Nazi Germany and Italy whereby the latter did not persecute Jews during World War II. The author explores the motives and forces underpinning Nazism and fascism and analyzes the issue of human responsibility in warfare.

This riveting, New York Times bestselling biography illuminates the life of Otto von Bismarck, the statesman who unified Germany but who also embodied everything brutal and ruthless about Prussian culture. Jonathan Steinberg draws heavily on contemporary writings, allowing Bismarck's friends and foes to tell the story. What rises from these pages is a complex giant of a man: a hypochondriac with the constitution of an ox, a brutal tyrant who could easily shed tears, a convert to an extreme form of evangelical Protestantism who secularized schools and introduced civil divorce. Bismarck may have been in sheer ability the most intelligent man to direct a great state in modern times. His brilliance and insight dazzled his contemporaries. But all agreed there was also something demonic, diabolical, overwhelming, beyond human attributes, in Bismarck's personality. He was a kind of malign genius who, behind the various postures, concealed an ice-cold contempt for his fellow human beings and a drive to control and rule them. As one contemporary noted: "e;the Bismarck regime was a constant orgy of scorn and abuse of mankind, collectively and individually."e;In this comprehensive and expansive biography--a brilliant study in power--Jonathan Steinberg brings Bismarck to life, revealing the stark contrast between the "e;Iron Chancellor's"e; unmatched political skills and his profoundly flawed human character.

Switzerland is a special and fascinating place. Its unique institutions, its direct democracy, multi-member executives, absence of strikes, communal autonomy, its universal military service, its wealth, and four national languages make it interesting in itself. But it has wider significance, in representing the 'Europe that did not happen', the Europe that escaped the centralisation of state and economy associated with the modern world. Today, there is a new special feature. Switzerland is an island surrounded by the European Union, and resists membership. Why Switzerland? attempts to answer three related questions: why has such an exception to European norms survived? Why should outsiders notice its peculiarities and what can they learn from them? Finally, can so unusual a society continue to exist when many of the conditions in which it evolved have disappeared?
