New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four dimensions in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic (or non-DNA cellular transmission of traits), behavioral, and symbolic (transmission through language and other forms of symbolic communication). These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution. After discussing each of the four inheritance systems in detail, Jablonka and Lamb put Humpty Dumpty together again by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional (and skeptical) I.M., or Ifcha Mistabra -- Aramaic for the opposite conjecture -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points.

    

    It begins by introducing students to the basics of communication systems without using probabilistic theory. Only after a solid knowledge base--an understanding of how communication systems work--has been built are concepts requiring probability theory covered. This third edition has been thoroughly updated and revised to include expanded coverage of digital communications. New topics discussed include spread-spectrum systems, cellular communication systems, global positioning systems (GPS), and an entire chapter on emerging digital technologies (such as SONET, ISDN, BISDN, ATM, and video compression). Ideal for the first communication systems course for electrical engineers, Modern Digital and Analog Communication Systems offers students a superb pedagogical style; it consistently does an excellent job of explaining difficult concepts clearly, using prose as well as mathematics. The author makes every effort to give intuitive insights--rather than just proofs--as well as heuristic explanations of theoretical results wherever possible. Featuring lucid explanations, well-chosen examples clarifying abstract mathematical results, and excellent illustrations, this unique text is highly informative and easily accessible to students.

    Science has seen its fair share of punch-ups over the years, but one debate, in the field of biology, has become notorious for its intensity. Over the last twenty years, Richard Dawkins and Stephen Jay Gould have engaged in a savage battle over evolution, which continues to rage even after Gould's death in 2002. Kim Sterelny moves beyond caricature to expose the real differences between the conceptions of evolution of these two leading scientists. He shows that the conflict extends beyond evolution to their very beliefs in science itself; and, in Gould?s case, to domains in which science plays no role at all.

    It is a protest at institutions that isolate, and a way of life that denies respect and responsibility for the weak.

    Coming eighteen years after the publication of The Ants, this new volume expands our knowledge of the social insects (among them, ants, bees, wasps, and termites) and is based on remarkable research conducted mostly within the last two decades. These superorganisms—a tightly knit colony of individuals, formed by altruistic cooperation, complex communication, and division of labor—represent one of the basic stages of biological organization, midway between the organism and the entire species. The study of the superorganism, as the authors demonstrate, has led to important advances in our understanding of how the transitions between such levels have occurred in evolution and how life as a whole has progressed from simple to complex forms. Ultimately, this book provides a deep look into a part of the living world hitherto glimpsed by only a very few.

    This is a comprehensive book specifically aimed at undergraduate students of engineering and conforming to the syllabi of major institutes teaching this subject. Adopting a direct, functional and practical approach, the book presents an exhaustive treatment of the basics of technical communication, both oral and written. It covers contemporary topics such as technical proposals, research papers, technical theses, dissertations, and instruction manuals. Also included are recent developments in communication technology such as the use of the Internet and contemporary software. With its up-to-date coverage and practical orientation, the book would prove to be an extremely useful text for students, while also serving as a ready reference for day-to-day communication.

     Kali is fierce. Meaning, when you use her mantra you are invoking a fierce energy. Her energy is not subtle.The results can be rather dramatic, Kali, the dark mother of the Hindu pantheon is oft the most misunderstood Goddess in all human spiritual endeavor. Her images often depict her as being an evil and demonic force that few should ever dare call upon whilst others worship her as benign Goddess whom bestows blessings upon her supplicants. She is , in fact, both of these . Kali will challenge the stuffiness and properness you have acquired in this life. She will challenge who you think you are. She will spit in your face, she will push your buttons and will humble you. She will make you face your demons. Cut away your pride. She will make you grow whether you feel you're ready or not. All for the sake of breaking you out of your shell, a shell you so readily hide in. Kali will throw you into your challenges raw. Thus, letting you learn on your own. She would be the one to push you into the deep end of the pool so you can learn to swim. She will show you the futility of your overly valued words and notions of yourself to which we all idolatrously worship. If you are ready to call Upon Kali then this book is for you.

    

    She is also the cleanest pig ever. She teaches other animals the need for cleanliness only to be betrayed by her own kind.
