You know that you need oxygen to breathe, that neon can glow and chrome shines?
But did you know that your cell phone contains arsenic, your spectacles contain rhodium and that the tin pest is not a disease?
And can you name just three researchers whom we have to thank for all these results?
Here, Professor Quadbeck-Seeger, a long-serving member of the board at BASF, goes in search of these and other questions.
Based on the periodic table, the key reference source for any natural scientist, he explains the criteria that define an element's position in the table and are responsible for its particular characteristics. In a clear and concise manner, he describes for each element the story behind its discovery, its physical and chemical properties as well as its role in our everyday lives.
Enriched by a wealth of interesting details, this beautifully designed book in full color represents not only varied reading, but also a treasure trove of surprising facts.
Elements of British and American English discusses in a systematic way the differences between Britsih and American English. It is primarily meant for secondary schol teachers of English, but can also be recommended to secondary school or university students, or practically anybody with a relatively good command of English
This unique text draws on the tools of modern linguistics to help the student acquire an effective understanding of learned, specialized, and scientific vocabulary. English Vocabulary Elements (EVE) helps develop familiarity with over 350 Latin and Greek word elements in English, and shows how these roots are the building blocks within thousands of different words. Along the way the authors introduce and illustrate many of the fundamental concepts of linguistics. Offering a thorough approach to the expansion of vocabulary, EVE is an invaluable resource that provides students a deeper understanding of the language.
This visual dictionary uses a combination of textual definitions and superb line drawings to illuminate essential terms in architectural elements, from the traditional houses to the huge office buildings.

The Periodic Table: Its Story and Its Significance The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the
periodic table by van Spronsen (1969), has been out of print for a onsiderable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and
interested lay-persons alike. The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been
interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to the classification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like Dobereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail. Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his
accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successive theories of the electron including Bohr's
quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early
electronic configurations published by Bohr and others. Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closes with an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain
