Featuring a foreword by the astronaut Ulf Merbold, this book is devoted to interfaces between two fluids, that is, between a liquid and a gas or between two liquids. It is the first review on the subject, providing an up-to-date overview.

Even today flying into space is an undertaking at the borderline of what is curreiitly feasible. h veq complex assen~bly of sophist~icated machinery is needed in order to reach orbit and return from there to Eart,ll safely. A11 ast,ronaut knows that only if t,he rocket engines, inertial navigat,ion platforms. hydraulic systems; generators of electrical power, att,itude control systems, life support sj stems, coinput~ers. data transmission equipment, heat shields and many other components work flawlessly can he or she accomplish a mission in good llealt,h. I11 other words there is risk, but the odds are better than even. How else could a man or a woman see the incredible beauty of our planet Earth from a clist,ance? Take t,he combination of it,s colours. white and blue. It is so breatht,akingly stunning, that most likely not even a poet could find words to adequately describe it. There is the curved line of the horizon with an incredibly black slij above it. L4t first sight it is evident how elidless and empty the universe actually is. The Eart,h's horizon is fringed with a royal blue seam, our at,mosphere. Its beauty and fragility are thrilling, and seen from orbit it is instantly apparent that there is not much air around us.

New feature

This book is devoted to interfaces between two fluids, that is, between a liquid and a gas (such as water and air) or between two liquids (such as water and oil). The main motivation for the book is twenty years of experimentation in the microgravity environment of space, and the associated theory. This unique environment has made possible numerous qualitative and quantitative observations of effects that are masked by gravity on earth. Large liquid surfaces have been created and their stability and dynamics have been studied. The experimental insights gained have, in turn, strongly stimulated further theoretical and mathematical investigations. Advancing and receding contact angles, wetting barriers, pinning of contact lines, oscillations of capillary surfaces and fluid sloshing are also discussed.
