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
Awarded the Booker Prize in 1981, Midnight's Children is Salman Rushdie's most highly regarded work of fiction, though not his best known. That distinction belongs to The Satanic Verses, the 1988 novel that prompted Iran's Ayatollah Ruhollah
Khomeini, who considered the book blasphemous, to declare Rushdie an enemy of Islam and put a $1.5 million bounty on his head. But in Midnight's Children, Rushdie had already produced a novel that not only risks offending some readers, but also fiercely challenges our understanding of history, nationhood, and narrative.

Computer Fun Math
By Lisa Trumbauer
Grade 3-5-These interactive activity books have brightly colored pages and lively text and illustrations that will appeal to youngsters. Math includes activities to create simple graphs and charts, make and use measuring tools, understand fractions, and design games. Science teaches students to collect and record data, track the weather, identify parts of an insect, and set up simple experiments. Each book starts with computer basics such as becoming familiar with the keyboard, monitor, and mouse but there are no diagrams or pictures of computer screens illustrating the functions described. Pages have numbered, step-by-step directions
enclosed in colored boxes that are sometimes difficult to read. The books are written in an informal style, with chatty remarks such as "duh-you knew that!" or "...old news, right?" While the subject matter is very elementary, the "how to" directions for following the computer activities require a more sophisticated
reading level. Most children won't have the skill or patience to read all of the directions on their own.
