Book Description
Excerpt from The Astronomical Journal, Vol. 34: September 1921, to January, 1923, Numbers 793-813 It would seem then that the connection between I'rccsepe and the Taurus cluster is not direct. An indirect connection, on the other hand, is a' very reasonable supposition. If we remove the effect of the solar motion from our results, the apices and absolute motions of the clusters are.

Book Description
This research monograph presents a new dynamical framework for the study of secular morphological evolution of galaxies along the Hubble sequence. Classical approaches based on Boltzmann’s kinetic equation, as well as on its moment-equation descendants the Euler and Navier-Stokes fluid equations, are inadequate for treating the maintenance and long-term evolution of systems containing self-organized structures such as galactic density-wave modes. A global and synthetic approach, incorporating correlated fluctuations of the constituent particles during a nonequilibrium phase transition, is adopted to supplement the continuum treatment. The cutting-edge research combining analytical, N-body simulational, and observational aspects, as well as the fundamental-physics connections it provides, make this work a valuable reference for researchers and graduate students in astronomy, astrophysics, cosmology, many-body physics, complexity theory, and other related fields. Contents Dynamical Drivers of Galaxy Evolution N-Body Simulations of Galaxy Evolution Astrophysical Implications of the Dynamical Theory Putting It All Together Concluding Remarks Appendix: Relation to Kinetics and Fluid Mechanics

Book Description
This comprehensive reference updates bistatic and multistatic radar developments since the publication of Nicholas Willis' seminal book Bistatic Radar published in 1991 and revised in 1995. The book is organized into two major sections: Bistatic/ Multistatic Radar Systems and Bistatic Clutter and Signal Processing. New and recently declassified military applications are documented. Civil applications are detailed for the first time, including commercial and scientific systems. Several of the most honored radar engineers of this era provide expertise in each of these applications. Professionals in radar and sonar will find this book a valuable resource

Book Description
The bright galaxies, star clusters, and nebulae catalogued in the late 1700s by the famous comet hunter Charles Messier are still the most widely observed celestial wonders in the sky. The second edition of Stephen James O'Meara's acclaimed observing guide to the Messier Objects features improved star charts for helping you find the objects, a much more robust telling of the history behind their discovery - including a glimpse into Messier's fascinating life - and updated astrophysical facts to put it all into context. These additions, along with new photos taken with the most advanced amateur telescopes, bring O'Meara's first edition more than a decade into the twenty-first century. Expand your universe and test your viewing skills with this truly modern Messier guide. It is a must for all budding night watchers.

Book Description
Many aspects of research activity in science are opaque to outsiders and this opacity infects how connections are made between science and other disciplines. The aim of Culture, Curiosity and Communication in Scientific Discovery is to try to shine a light through the mist of scientific research by way of examples taken from the sciences, social sciences and the humanities. The book maintains that the foundations of science are built on sand because theories come and go and the search for truth is elusive. Knowledge acquisition appears to be an end in itself, as though knowledge is some sort of commodity or object that can be traded. Nigel Sanitt explains that we have created a mythical objective world, where we pretend that opinions and values are generated by data alone and not by human beings. Science is part of our culture and part of the understanding of science is bound up with recognizing the social, economic and political ramifications as they apply to science. Culture, Curiosity and Communication in Scientific Discovery is a radical interpretation of how science works and aims to change the way scientists and non-scientists think about science.
