Matter is the material substance that constitutes our whole observable universe, and it is the subject of study of physics. Life science, for instance, covers, as you might expect, the living world - micro life, fungi, plants and plant reproduction, animals and animal reproduction, inheritance, bones and muscles, blood and breathing, digestion, health, food chains, ecosystems, staying alive, the earth's cycles and the carbon cycle. Though most articles are solicited by Editors, suggestions for new articles and authors as well as corrections to existing articles are always welcome: Contact Us. Jaw-dropping 3D computer-generated images burst from the pages, detailing the tiny atoms that make up our Universe and the incredible forces that keep it all together.

The SAGE Encyclopedia of Theoryis a landmark work serving as something of a capstone to 10 prior SAGE encyclopedias that examined theory in specific social science disciplines (psychology, sociology, education, political science, etc. SAGE Knowledge is the premier social sciences platform for SAGE and CQ Press book, reference and video content.Humankind's fascination with the world beyond Earth has led to many landmark moments in history, as when space exploration took a giant step forward with the advent of technology that allowed humans to successfully travel to the Moon and to build spacecraft capable of exploring the rest of the solar system and beyond. This contained text updates through 1995, hundreds of book covers and author photos, a small number of old film trailers, and author video clips taken from the TVOntario series Prisoners of Gravity. US author and poet who began publishing sf with A Landscape of Darkness ( 1990), an sf adventure in which a mercenary on a colony planet must pit himself against an Alien who wears the guise of a Japanese warrior. It comes with simple text, photographs and illustrations, fun science activities and exciting recommended Web sites.

What, in short, is the prime repository and vehicle for the knowledge that has been acquired in any discipline over the course of its development? Consider the fact that many plants not only serve up crucial nutrients and breathable air but also look good doing it. From absolute zero to the Mesozoic era to semiconductors to the twin paradox, Trefil and his co-authors offer an accessible universe (as accessible as the universe gets, anyway).All the sections are colour coded, so you only need to look at the colour bar along the bottom of the pages to see which section you're looking at.

Theories are part and parcel of just about every human activity that involves knowing about the world and our place in it. His books include The Thermodynamics of Pizza (1991), Entropy and the Magic Flute (1993), and The Kindly Dr. Part of DK's hugely successful Knowledge Encyclopedia series, this is the perfect accompaniment to the school syllabus and an essential addition to every family library. Plants occupy the base of Earth's food webs and are consumed directly or indirectly by all higher life-forms, thereby functioning as the major source of food for humans and other animals. This evolutionary link highlights the way in which seemingly incongruous creatures can, in fact, share a common ancestor (though that doesn't mean that we should expect waterfowl and crocodiles to become friends anytime soon).Biological diversity is key to a healthy ecosystem, whether it’s a small biological community or the global biosphere. This 6th edition has been fully updated and includes 34 new entries on key scientific topics in the news bringing the total number of entries over 2,600.
