Sommario/riassunto

This is the international edition of Prof Rao's popular science book, an elementary introduction intended for high school students and others interested in appreciation of chemistry. Ideas and facts are presented, and a few questions raised, in order to interest the reader in the subject and to arouse curiosity. The book covers essential aspects of chemistry, features of the modern periodic table, bonding between atoms in molecules and substances, shapes and structures of molecules, metals and materials, alkalis and acids, carbon compounds, electronic structure of atoms, classification of elements, simple chemical reactions, biopolymers and man-made polymers and aspects of energy. There are also life sketches of chemists and procedures for a few experiments.

Sommario/riassunto

Edward Gibbon laid the fall of the Roman Empire at Christianity's door, suggesting that 'pusillanimous youth preferred the penance of the monastic to the dangers of a military life ... whole legions were buried in these religious sanctuaries'. This surprising 2007 study suggests that, far from seeing Christianity as the cause of the fall of the Roman Empire, we should understand the Christianisation of the household as a central Roman survival strategy. By establishing new 'ground rules' for marriage and family life, the Roman Christians of the last century of the Western empire found a way to re-invent the Roman family as a social institution to weather the political, military, and social upheaval of two centuries of invasion and civil war. In doing so, these men and women - both clergy and lay - found themselves changing both what it meant to be Roman, and what it meant to be Christian.
