The "Large Sutra on Perfect Wisdom" took shape between 50 and 2000 A.D. in southern India during one of the most momentous outbursts of religious creativity in human history.

Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World contains the contributions presented at the ITA-AITES World Tunnel Congress 2023 (Athens, Greece, 12 – 18 May, 2023). Tunnels and underground space are a predominant engineering practice that can provide sustainable, cost-efficient and environmentally friendly solutions to the ever-growing needs of modern societies. This underground expansion in more diverse and challenging infrastructure types or to novel underground uses can foster the changes needed. At the same time, the tunneling and underground space community needs to be better prepared and equipped with knowledge, tools and experience, to deal with the prevailing conditions, to successfully challenge and overcome adversities on this path. The papers in this book aim at contributing to the analysis of challenging conditions, the presentation and dissemination good practices, the introduction of new concepts, new tools and innovative elements that can help engineers and all stakeholders to reach their end goals. Expanding Underground - Knowledge and Passion to Make a Positive Impact on the World covers a wide range of aspects and topics related to the whole chain of the construction and operation of underground structures: Knowledge and Passion to Expand Underground for Sustainability and Resilience Geological, Geotechnical Site Investigation and Ground Characterization Planning and Designing of Tunnels and Underground Structures Mechanised Tunnelling and Microtunnelling Conventional Tunnelling, Drill-and-Blast Applications Tunnelling in Challenging Conditions - Case Histories and Lessons Learned Innovation, Robotics and Automation BIM, Big Data and Machine Learning Applications in Tunnelling Safety, Risk and Operation of Underground Infrastructure, and Contractual Practices, Insurance and Project Management The book is a must-have reference for all professionals and stakeholders involved in tunneling and underground space development projects.

Train your brain with the secrets behind the world's toughest feat of memory: the London Knowledge The Knowledge is a unique book: a guide to getting more out of your brain and your city. A fully illustrated, lovingly detailed look at London's best kept secrets, it will also take you down the pathways of your mind and teach you how to keep your memory sharp. Written by a licensed London cab driver and tour guide, The Knowledge is the first ever book to take readers inside the legendarily difficult - and fast-vanishing - set of skills that all licensed cab drivers must have: a perfect , thoroughly tested knowledge of every street, alley, turning and landmark of London. The black cab is an iconic symbol of London, but to drive it, prospective cabbies must take what is often considered the world's hardest exam, involving learning every street, turning and waypoint along 320 different routes across London, along with every landmark within 1/4 of a mile of the start and end of each route: altogether 25,000 streets and 2,000 places of interest. Learning the Knowledge takes years, and dozens of appearances at gruelling oral exams, but those who pass become part of a unique partnership, with no parallel anywhere in the world. Scientific studies have consistently shown that London cabbies who have passed the Knowledge have enlarged brains and near-superhuman memory capacities. The Knowledge is the first book to take readers inside the extraordinary mind of the cabbie, with 50 real Knowledge routes across London, beautifully mapped and illustrated to show the streets and landmarks, with notes on their hidden histories and popular associations, and sections allowing the reader to test their memory on these routes, accompanied with an introduction discussing the history and science of the Knowledge and guides to memory-training techniques used by cabbies and memory champions around the world.
