Did A Dinosaur Drink This Water? (pb)
The author of Can You Count to a Googol? explains the complete water cycle and also discusses ocean currents, ocean and lake habitats, and hydroelectricity, touching on water pollution and our responsibility to keep our water clean. Simultaneous.
Intense Light And Water
Laser processing of solid materials has been commonly performed in gas ambient. Having the workpiece immersed into liquid, having a liquid film on it, or soaking the material with liquid gives several advantages such as removal of the debris, lowering the heat load on the workpiece, and confining the vapour and plasma, resulting in higher shock pressure on the surface.
Introduced in the 1980s, neutral liquids assisted laser processing (LALP) has proved to be advantageous in the cutting of heat-sensitive materials, shock peening of machine parts, cleaning of surfaces, fabrication of micro-optical components, and for generation of nanoparticles in liquids. The liquids used range from water through organic solvents to cryoliquids.
The primary aim of the book is to present the essentials of previous research (tabulated data of experimental conditions and results), and help researchers develop new processing and diagnostics techniques (presenting data of liquids and a review of physical phenomena associated with LALP). Engineers can use the research results and technological innovation information to plan their materials processing tasks.
Laser processing in liquids has been applied to a number of different tasks in various fields such as mechanical engineering, microengineering, chemistry, optics, and bioscience. A comprehensive glossary with definitions of the terms and explanations has been added.
The book covers the use of chemically inert liquids under normal conditions. Laser chemical processing examples are presented for comparison only.

- Glossary of over 200 terms and abbreviations
The Water-witch; Or, The Skimmer Of The Seas
The fine estuary which penetrates the American coast, between the fortieth and forty-first degrees of latitude, is formed by the confluence of the Hudson, the Hackensack, the Passaic, the Raritan, and a multitude of smaller streams; all of which pour their tribute into the ocean, within the space named. The islands of Nassau and Staten are happily placed to exclude the tempests of the open sea, while the deep and broad arms of the latter offer every desirable facility for foreign trade and internal intercourse. To this fortunate disposition of land and water, with a temperate climate, a central position, and an immense interior, that is now penetrated, in every direction, either by artificial or by natural streams, the city of New-York is indebted for its extraordinary prosperity. Though not wanting in beauty, there are many bays that surpass this in the charms of scenery; but it may be questioned if the world possesses another site that unites so many natural advantages for the growth and support of a widely extended commerce. As if never wearied with her kindness, Nature has placed the island of Manhattan at the precise point that is most desirable for the position of a town. Millions might inhabit the spot, and yet a ship should load near every door; and while the surface of the land just possesses the inequalities that are required for health and cleanliness, its bosom is filled with the material most needed in construction.

The Vacation (a Bisexual Watersports Story)
Millie and Gabe just got engaged. As a way of celebration they choose to take a vacation to Bahamas. Of course they couldn't leave Dave behind. They had planned it all. But Millie has been a bad girl, wetting herself and humping a stranger on the plane. Hence, her men decide to punish her by keeping her without sex, which for a healthy twenty year old girl is more than a punishment. It's a disaster. Oh, but Millie has her own ideas about how this vacation should go so, although Gabe and Dave try to soften her with a big surprise, she chooses to cast her own sexual punishment.
