Book Description
"Water is an extraordinary substance. It owes its characteristic anomalous properties to a network of strong hydrogen bonds present between water molecules. In ice, water molecules hold regular positions in the crystal. Nevertheless, the behaviour of ice can be dynamic and exciting, especially at the surface. At temperatures well below bulk melting, the surface of ice is covered by a liquid premelted layer. This water layer governs many geophysical processes and plays a role in the low friction of ice. This thesis describes several properties of ice and ice-related systems at the molecular level. For this purpose we have employed a variety of spectroscopic techniques and made use of stretching vibrations as sensitive probes of the molecular structure. The position, amplitude, and width of the stretching bands are utilized to describe the molecular properties and structure. The vibrational dynamics of water molecules in ice and hydrated salts are studied in Chapters 4 and 5. The surface properties of ice and the premelting of the surface are investigated in Chapters 6 and 7. Chapter 8 deals with the effects of resonant molecular couplings on the surfaces of ice and liquid water. In the last two chapters we studied the surface properties of water and oil emulsions. The effect of freezing water on the surface of oil droplets in water is investigated in Chapter 9. The surface structure of water droplets and ice nanocrystals immersed in a hydrophobic environment is discussed in Chapter 10."--Samenvatting auteur.

Book Description
Join Bartholomew Cubbins in Dr. Seuss’s Caldecott Honor–winning picture book about a king’s magical mishap! Bored with rain, sunshine, fog, and snow, King Derwin of Didd summons his royal magicians to create something new and exciting to fall from the sky. What he gets is a storm of sticky green goo called Oobleck—which soon wreaks havock all over his kingdom! But with the assistance of the wise page boy Bartholomew, the king (along with young readers) learns that the simplest words can sometimes solve the stickiest problems.

Book Description
Supplying water to millions is not simply an engineering and logistical challenge. As David Soll shows in his finely observed history of the nation’s largest municipal water system, the task of providing water to New Yorkers transformed the natural and built environment of the city, its suburbs, and distant rural watersheds. Almost as soon as New York City completed its first municipal water system in 1842, it began to expand the network, eventually reaching far into the Catskill Mountains, more than one hundred miles from the city. Empire of Water explores the history of New York City’s water system from the late nineteenth century to the early twenty-first century, focusing on the geographical, environmental, and political repercussions of the city’s search for more water. Soll vividly recounts the profound environmental implications for both city and countryside. Some of the region’s most prominent landmarks, such as the High Bridge across the Harlem River, Central Park’s Great Lawn, and the Ashokan Reservoir in Ulster County, have their origins in the city’s water system. By tracing the evolution of the city’s water conservation efforts and watershed management regime, Soll reveals the tremendous shifts in environmental practices and consciousness that occurred during the twentieth century. Few episodes better capture the long-standing upstate-downstate divide in New York than the story of how mountain water came to flow from spigots in Brooklyn and Manhattan. Soll concludes by focusing on the landmark watershed protection agreement signed in 1997 between the city, watershed residents, environmental organizations, and the state and federal governments. After decades of rancor between the city and Catskill residents, the two sides set aside their differences to forge a new model of environmental stewardship. His account of this unlikely environmental success story offers a behind the scenes perspective on the nation’s most ambitious and wide-ranging watershed protection program.

Book Description
A landmark book by marine biologist Wallace J. Nichols on the remarkable effects of water on our health and well-being. Why are we drawn to the ocean each summer? Why does being near water set our minds and bodies at ease? In Blue Mind, Wallace J. Nichols revolutionizes how we think about these questions, revealing the remarkable truth about the benefits of being in, on, under, or simply near water. Combining cutting-edge neuroscience with compelling personal stories from top athletes, leading scientists, military veterans, and gifted artists, he shows how proximity to water can improve performance, increase calm, diminish anxiety, and increase professional success. Blue Mind not only illustrates the crucial importance of our connection to water; it provides a paradigm shifting "blueprint" for a better life on this Blue Marble we call home.

Book Description
Thermodynamics and Statistical Mechanics Thermodynamics and Statistical Mechanics An Integrated Approach This textbook brings together the fundamentals of the macroscopic and microscopic aspects of thermal physics by presenting thermodynamics and statistical mechanics as complementary theories based on small numbers of postulates. The book is designed to give the instructor flexibility in structuring courses for advanced undergraduates and/or beginning graduate students and is written on the principle that a good text should also be a good reference. The presentation of thermodynamics follows the logic of Clausius and Kelvin while relating the concepts involved to familiar phenomena and the modern student’s knowledge of the atomic nature of matter. Another unique aspect of the book is the treatment of the mathematics involved. The essential mathematical concepts are briefly reviewed before using them, and the similarity of the mathematics to that employed in other fields of physics is emphasized. The text gives in-depth treatments of low-density gases, harmonic solids, magnetic and dielectric materials, phase transitions, and the concept of entropy. The microcanonical, canonical, and grand canonical ensembles of statistical mechanics are derived and used as the starting point for the analysis of fluctuations, blackbody radiation, the Maxwell distribution, Fermi-Dirac statistics, Bose-Einstein condensation, and the statistical basis of computer simulations.
