Dante: De vulgari eloquentia (Medieval Classics)

De vulgari eloquentia, written by Dante in the early years of the fourteenth century, is the only known work of medieval literary theory to have been produced by a practicing poet, and the first to assert the intrinsic superiority of living, vernacular languages over Latin.

Knives and Scabbards - Medieval Finds from Excavations in London

Knives were vital to medieval man for a whole range of uses, from the domestic to the wider social context: Anglo-Saxon pre-Christian burials bear silent witness to this dependence in the many cases where knives are found among the grave-goods. Forged and hafted with great skill, sometimes with elaborately decorated scabbards, knives are of intrinsic fascination, besides being indicators of the popular artistic tastes of the time.

Functional Inequalities Markov Semigroups and Spectral Theory

In this book, the functional inequalities are introduced to describe:
(i) the spectrum of the generator: the essential and discrete spectrums, high order eigenvalues, the principle eigenvalue, and the spectral gap;
(ii) the semigroup properties: the uniform intergrability, the compactness, the convergence rate, and the existence of density;
(iii) the reference measure and the intrinsic metric: the concentration, the isoperimetic inequality, and the transportation cost inequality.

 From an historical perspective, this text presents an entirely non- mathematical introduction to astronomy from the first endeavours of the ancients to the current developments in research enabled by cutting edge technological advances. Free of mathematics and complex graphs, the book nevertheless explains deep concepts of space and time, of relativity and quantum mechanics, and of origin and nature of the universe. It conveys not only the intrinsic fascination of the subject, but also the human side and the scientific method as practised by Kepler, defined and elucidated by Galileo, and then demonstrated by Newton.
