Scientists categorize the chemical elements as metals, nonmetals, and metalloids largely based on the elements' abilities to conduct electricity at normal temperatures and pressures, but there are other distinctions taken into account when classifying the elements in the periodic table. The alkali metals, for example, are metals, but have such special properties that they are given their own classification. The same is true for the alkaline earths.
Alkali and Alkaline Earth Metals presents the current scientific understanding of the physics, chemistry, geology, and biology of these two families of elements, including how they are synthesized in the universe, when and how they were discovered, and where they are found on Earth. With information pertaining to the discovery and naming of these elements as well as new developments and dilemmas, this new book examines how humans use alkalis and alkaline earths and their benefits and challenges to society, health, and the environment. Lithium, sodium, potassium, magnesium, and calcium are only a few of the topics covered in this full-color resource. Alkali and Alkaline Earth Metals provides students and scientists with an up-to-date understanding of each of the nonmetals—where they came from, how they fit into our current technological society, and where they may lead us. |

Global warming is accelerating faster than the ability for natural repair, and environmental stresses are damaging ecosystems, all affecting physical and biological systems on Earth. A new Nasa-led study shows that human activity has caused climate changes resulting in permafrost thawing, acid rain, and lower productivity in lakes as well as increased emissions of greenhouse gases, including CO2, N20, CH4, CF3, and CFC. Marine plants play a vital role in maintaining the balance of marine environments, while serving as a source of food for humankind and important chemical compounds. Microalgae and seaweed have enormous potential for reducing global warming and climate change. During photosynthesis algae grow, draw CO2 from the atmosphere, release oxygen, and produce solar biofuel. Experts in the life of marine plant ecosystems in globally changing environments contributed chapters to this book. The target readers are phycologists, ecologists, atmospheric scholars, conservationists, environmentalists, and ecologically aware laymen.

Эффектное название, возможно, и интригует, но, уж конечно, ничего не объясняет. А в этой книге довольно серьезно рассказывается о том, чего достигла физика со времен Галилея до Эйнштейна, о явлениях древних, как мир, и, по-видимому, всем знакомых, а в конечном счете - о специальной теории относительности. |
