Eric R. Scerri, The Periodic Table: Its Story and Its Significance

Oxford University Press, USA | ISBN: 0195305736 | 2006-09-15 | 368 pages | PDF | 4.5 Mb​


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 considerable 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.

The Geometry and Topology of Three-Manifolds

Publisher: Mathematical Sciences Research Institute | ISBN: N\A | edition 2002 | PDF | 379 pages | 32 mb
The author's intent is to describe the very strong connection between geometry and lowdimensional topology in a way which will be useful and accessible (with some effort) to graduate students and mathematicians working in related fields, particularly 3-manifolds and Kleinian groups.

Paul W. Zitzewitz, T. G. Elliott, Haase, Kathleen A. Harper, Herzog, Nelson, Friedrich Schiller, Zorn, "Physics: Principles and Problems"
McGraw-Hill/Glencoe | 2005 | ISSN: 0078458137 | PDF | 943 pages | 36 MB
"PHYSICS: Principles and Problems" offers integrated support, abundant opportunities for problem solving, and a variety of realistic applications. The program has a balance of good conceptual presentation with a strong problem-solving strand. All the program resources are organized in a way that meets the needs of students in a diverse classroom. Also included are high-interest special features that connect physics to everyday life: How it Works, Technology and Society, Future Technology, and Extreme Physics.

Features:
- Actively involves students through Launch Labs - inquiry-based labs at the beginning of each chapter.
- Addresses student needs with a consistent three-step Example Problem that includes helpful math hints that students can use as they work through problems.
- Coaches students with blue annotations in the Example Problems. Practice Problems provide immediate feedback so every student has the opportunity to master skills that apply to related physics concepts.
- Helps students see the direct connections between math and physics principles. Connecting Math to Physics offers additional math support for every student.
- Motivates students with Challenge Problems that are designed after the open-ended questions on the Advanced Placement Physics exam with more in-depth applications and problem solving.
