Book Description
Based on the lecture notes of a school titled ‘Tides in Astronomy and Astrophysics’ that brought together students and researchers, this book focuses on the fundamental theories of tides at different scales of the universe—from tiny satellites to whole galaxies—and on the most recent developments. It also attempts to place the study of tides in a historical perspective. Starting with a general tutorial on tides, the theme of tides is approached in 9 chapters from many directions. They allow non-experts to pick up a physical intuition and a sense of orders of magnitude in the theory of tides. These carefully prepared lecture notes by leaders in the field include many illustrative figures and drawings. Some even offer a variety of simple back-of the-envelope problems.

Book Description
Nobody should have a monopoly of the truth in this universe. The censorship and suppression of challenging ideas against the tide of mainstream research, the blacklisting of scientists, for instance, is neither the best way to do and filter science, nor to promote progress in the human knowledge. The removal of good and novel ideas from the scientific stage is very detrimental to the pursuit of the truth. There are instances in which a mere unqualified belief can occasionally be converted into a generally accepted scientific theory through the screening action of refereed literature and meetings planned by the scientific organizing committees and through the distribution of funds controlled by "club opinions". It leads to unitary paradigms and unitary thinking not necessarily associated to the unique truth. This is the topic of this book: to critically analyze the problems of the official (and sometimes illicit) mechanisms under which current science (physics and astronomy in particular) is being administered and filtered today, along with the onerous consequences these mechanisms have on all of us. Apart from the editors, Juan Miguel Campanario, Brian Martin, Wolfgang Kundt, J. Marvin Herndon, Marian Apostol, Halton C. Arp, Tom Van Flandern, Andrei P. Kirilyuk, Dmitri Rabounski and Henry H. Bauer, all of them professional researchers, reveal a pessimistic view of the miseries of the actual system, while a glimmer of hope remains in the "leitmotiv" claim towards the freedom in doing research and attaining an acceptable level of ethics in science.

Book Description
From Cnut to D-Day: the history and science of the unceasing tide explored for the first time. Half of the world's population lives in coastal regions lapped by tidal waters. Yet how little most of us know about the tide. Our ability to predict and understand the tide depends on centuries of science, from the observations of Aristotle and the theories of Newton to today's supercomputer calculations. This story is punctuated here by notable tidal episodes in history, from Caesar's thwarted invasion of Britain to the catastrophic flooding of Venice, and interwoven with a rich folklore that continues to inspire art and literature today. With Aldersey-Williams as our guide to the most feared and celebrated tidal features on the planet, from the original maelstrøm in Scandinavia to the world's highest tides in Nova Scotia to the crumbling coast of East Anglia, the importance of the tide, and the way it has shaped - and will continue to shape - our civilization, becomes startlingly clear.

Book Description
Any model of tides is based on a specific hypothesis of how lagging depends on the tidal-flexure frequency X. For example, Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) assumed constancy of the geometric lag angle delta, while Singer (1968) and Mignard (1979, 1980) asserted constancy of the time lag Delta t. Thus each of these two models was based on a certain law of scaling of the geometric lag: the Gerstenkorn-MacDonald-Kaula theory implied that delta~X(0), while the Singer-Mignard theory postulated delta~X(1). The actual dependence of the geometric lag on the frequency is more complicated and is determined by the rheology of the planet. Besides, each particular functional form of this dependence will unambiguously fix the appropriate form of the frequency dependence of the tidal quality factor, Q(X). Since at present we know the shape of the function Q(X), we can reverse our line of reasoning and single out the appropriate actual frequency dependence of the lag, delta(X): as within the frequency range of our concern Q ~ X(alpha), a = 0.2 - 0.4, then delta ~ X( -alpha). This dependence turns out to be different from those employed hitherto, and it entails considerable alterations in the timescales of the tide-generated dynamical evolution. Phobos's fall on Mars is an example we consider.

Book Description
The tide is the greatest synchronised movement of matter on our planet. Every drop of seawater takes part in tidal motion, driven by the gravitational pull of the moon and sun. At the coast, we see the tide as a twice-daily rise and fall of sea level that moves the edge of the sea up and down a beach or cliff-face. In some places, the tide is small but at others it can rise in a few hours by the height of a three storey building; it then has to be treated with great respect by those who live and work by the sea. In this Very Short Introduction David George Bowers and Emyr Martyn Roberts explore what we know about the tides. Blending clear explanations of well known tidal phenomena with recent insights in the deep ocean and coastal seas, Bowers and Roberts use examples from around the world, to tell the story of the tide, considering its nature and causes, its observation and prediction, and unusual tides and their relevance. They explore why tides have attracted the attention of some of the world's greatest scientists, from the initial challenge of explaining why there are two tides a day when the moon and sun pass overhead just once; a problem that was solved by Isaac Newton. In the 19th century, scientists unravelled the rhythms of the tide; good tidal predictions in the form of tide tables were then possible. The predictions were made on beautiful tide predicting machines constructed of brass and mahogany, some of which can still be seen in maritime museums. In the 20th century, the importance of tides as mixers of sea water became evident. As Bowers and Roberts explore, tidal mixing of the ocean is essential for maintaining its deep circulation, a key part of the climate-control system of our planet. In inshore waters, tidal mixing enhances biological productivity, influences sea temperature and turbidity and creates dramatic features such as maelstroms and tidal bores. In the 21st century, space probes are examining the effects of tidal processes on the moons of Jupiter and Saturn and the possibility of tidally-heated liquid oceans with their own ecosystems. Looking to the cutting edge of tidal research, Bowers and Roberts also consider how we can study the role of the tide in the geological and biological evolution of our own planet with innovative computer models.
