Free Download Quiet Works: Making Silence the Secret Ingredient of the Workday by Joseph McCormack English | October 15, 2024 | ISBN: 1637745699 | 256 pages | PDF | 7.66 Mb We live-and work-in a world of nonstop noise. It's time to reimagine how we work and make silence the secret ingredient.  Free Download Quarkus in Action by Martin Štefanko and Jan Martiška English | 2025 | ISBN: 163343947X | 417 pages | True PDF | 15.97 MB  Free Download Prof. David B Beard PhD, "Quantum Mechanics with Applications " English | ISBN: 0486779904 | 2014 | 352 pages | EPUB | 7 MB This introductory text emphasizes Feynman's development of path integrals and its application to wave theory for particles. Suitable for undergraduate and graduate students of physics, the well-written, clear, and rigorous text was written by two of the nation's leading authorities on quantum physics. A solid foundation in quantum mechanics and atomic physics is assumed.  Free Download Quantum Mechanics of One- and Two-Electron Atoms by Hans A. Bethe , Edwin E. Salpeter English | PDF | 1977 | 379 Pages | ISBN : 0306200228 | 43.9 MB This book was written twenty years ago, but we are leaving it unchanged - not because little has happened to the subject, but because so much has happened that any change would require very major rewriting. On the other hand, no other book on the subject seems to have appeared and we hope this paperback edition will be of some use to a younger generation - if not for another twenty years, at least until someone else has the patience to write a new book. Although we have added no new material we have corrected some misprints. We have added new references only where they correct actual errors. We are grateful to Drs. G. Feinberg, M. Inokuti, Y. Kim, and A. Petermann for pointing out errors. Nearly all of this book is taken from an article prepared for a volume of the Encyclopedia of Physics. This article, in turn, is partly based on Dr. Norbert Rosenzweig's translation of an older article on the same subject, written by one of us (H.A.B.) about 25 years ago for the Geiger-Scheel Handbuch der Physik. To the article written last year we have added some Addenda and Errata. These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes.

These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes. The aim of this book is two-fold. First, to act as a reference work on calcu lations pertaining to hydrogen-like and helium-like atoms and their comparison with experiments. However, these calculations involve a vast array of approximation methods, mathematical tricks and physical pictures, which are also useful in the application of quantum mechanics to other fields. In many sections we have given more general discussions of the methods and physical ideas than is necessary for the study of the H- and He-atom alone. We hope that this book will thus at least partly fulfill its second aim, namely to be of some use to graduate students who wish to learn "applied quantum mechanics". A basic knowledge of the principles of quantum mechanics, such as given in the early chapters of Schiff's or Bohm's book, is presupposed.

 Free Download Protected Areas and Tourism in Southern Africa (Routledge Studies in Conservation and the Environment) By Lesego Senyana Stone (editor), Moren Tibabo Stone (editor), Patricia Kefilwe Mogomotsi (editor), Goemeone E.J. Mogomotsi (editor) 2023 | 310 Pages | ISBN: 1032044349 | EPUB | 1 MB This volume discusses the complex relationship between Protected Areas and tourism and their impact on community livelihoods in a range of countries in Southern Africa.Protected areas and tourism have an enduring and symbiotic relationship. While protected areas offer a desirable setting for tourism products, tourism provides revenue that can contribute to conservation efforts. This can bring benefits to local communities, but it can also have a negative impact, with the establishment of protected areas leading to the eviction of local communities from their original places of residence, while also preventing them from accessing the natural resources they once enjoyed. Taking a multi-disciplinary approach, this book addresses the opportunities and challenges faced by communities and other stakeholders as they endeavour to achieve their conservation goals and work towards improving community livelihoods. Case studies from Botswana, Malawi, Namibia, South Africa, Tanzania, Zambia and Zimbabwe address key issues such as human-wildlife conflicts, ecotourism, wildlife-based tourism, landscape governance, wildlife crop-raiding and trophy hunting, including the high-profile case of Cecil the lion. Chapters highlight both the achievements and positive outcomes of protected areas, but also the challenges faced and their impact on how protected areas are viewed and also conservation priorities more generally. The volume gives these issues affecting protected areas, local communities, managers and international conservation efforts centre stage in order inform policy and improve practice going forward.This book will be of great interest to students and scholars of conservation, natural resource management, tourism, sustainable development and African studies, as well as professionals and policymakers involved in conservation policy.
