This book covers thirty years of the Leningrad Mathematical Olympiad, which was, ostensibly, the very first formally organized, open, official city-level mathematical contest in the world. Founded in 1934 by a group of dedicated Soviet mathematicians, it played an outstanding (and often underappreciated) role in creating the Leningrad (St. Petersburg) school of mathematics of the 20th century.The book begins with the extensive introduction containing two prefaces (one of them written specifically for this edition), a large historical survey of the Leningrad Mathematical Olympiad, a section describing the logistical side of the contest, and a small chapter dedicated to the very first Mathematical Olympiad held in 1934, whose problems were recently found in the Soviet-era library archives.The main text contains approximately 1,100 highly original questions for students of grades 5 through 10 (ages 11-12 through 17-18) offered at the two concluding rounds of the Leningrad City Mathematics Olympiads in the years of 1961-1991. Full solutions, hints and answers are provided for all questions with very rare exceptions.It also includes 120 additional questions, offered at the various mathematical contests held in Leningrad over the same thirty-year period — on average, their difficulty is somewhat higher than that of the regular Mathematical Olympiad problems.

Introduction to Deep Learning and Neural Networks with Python (TM): A Practical Guide is an intensive step-by-step guide for neuroscientists to fully understand, practice, and build neural networks. Providing math and Python (TM) code examples to clarify neural network calculations, by book's end readers will fully understand how neural networks work starting from the simplest model Y=X and building from scratch. Details and explanations are provided on how a generic gradient descent algorithm works based on mathematical and Python (TM) examples, teaching you how to use the gradient descent algorithm to manually perform all calculations in both the forward and backward passes of training a neural network.

From the hair of a famous dead poet to botanical ornaments and meat pies, the subjects of this book are dynamic, organic artifacts. A cross-disciplinary collection of essays, Organic Supplements examines the interlaced relationships between natural things and human beings in early modern and eighteenth-century Europe. The material qualities of things as living organisms - and things that originate from living organisms - enabled a range of critical actions and experiences to take place for the people who wore, used, consumed, or perceived them.

Jesuit engagement with natural philosophy during the late 16th and early 17th centuries transformed the status of the mathematical disciplines and propelled members of the Order into key areas of controversy in relation to Aristotelianism. Through close investigation of the activities of the Jesuit 'school' of mathematics founded by Christoph Clavius, The Scientific Counter-Revolution examines the Jesuit connections to the rise of experimental natural philosophy and the emergence of the early scientific societies. Arguing for a re-evaluation of the role of Jesuits in shaping early modern science, this book traces the evolution of the Collegio Romano as a hub of knowledge. Starting with an examination of Clavius's Counter-Reformation agenda for mathematics, Michael John Gorman traces the development of a collective Jesuit approach to experimentation and observation under Christopher Grienberger and analyses the Jesuit role in the Galileo Affair and the vacuum debate. Ending with a discussion of the transformation of the Collegio Romano under Athanasius Kircher into a place of curiosity and wonder and the centre of a global information gathering network, this book reveals how the Counter-Reformation goals of the Jesuits contributed to the shaping of modern experimental science.

In the visionary tradition of Rachel Carson's "Silent Spring, One Square Inch of Silence "alerts us to beauty that we take for granted and sounds an urgent environmental alarm. Natural silence is our nation's fastest-disappearing resource, warns Emmy-winning acoustic ecologist Gordon Hempton, who has made it his mission to record and preserve it in all its variety--before these soul-soothing terrestrial soundscapes vanish completely in the ever-rising din of man-made noise. Recalling the great works on nature written by John Muir, John McPhee, and Peter Matthiessen, this beautifully written narrative, co-authored with John Grossmann, is also a quintessentially American story--a road trip across the continent from west to east in a 1964 VW bus. But no one has crossed America like this. Armed with his recording equipment and a decibel-measuring sound-level meter, Hempton bends an inquisitive and loving ear to the varied natural voices of the American landscape--bugling elk, trilling thrushes, and drumming, endangered prairie chickens. He is an equally patient and perceptive listener when talking with people he meets on his journey about the importance of quiet in their lives. By the time he reaches his destination, Washington, D.C., where he meets with federal officials to press his case for natural silence preservation, Hempton has produced a historic and unforgettable sonic record of America. With the incisiveness of Jack Kerouac's observations on the road and the stirring wisdom of Robert Pirsig repairing an aging vehicle and his life, "One Square Inch of Silence "provides a moving call to action. More than simply a book, it is an actual place, too, located in one of America's last naturally quiet places, in Olympic National Park in Washington State.

Elgar Research Agendas outline the future of research in a given area. Leading scholars are given the space to explore their subject in provocative ways, and map out the potential directions of travel. They are relevant but also visionary. Within the span of a generation, innovation and entrepreneurship have emerged as two of the most vital forces in the economy and in society. This Research Agenda highlights new insights and approaches to guide future thinking, research and policy in the area. To accomplish this, the editors have brought together a group of accomplished scholars spanning economics, management, public policy and finance. Drawing on the experiences and insights of leading scholars this Research Agenda covers a broad array of rich and promising topics, including entrepreneurial ecosystems, finance and the role of universities. Focusing on the intersection and overlap between the two disciplines, the Research Agenda begins by establishing the theoretical basis between the two topics, before exploring impact, context, academic entrepreneurship, start-ups, policy and corporate governance. The book concludes with three provocative chapters: Friederike Welter highlighting the power of words and images, Sameeksha Desai discussing the role of artificial intelligence and Mark Casson presenting a case for radical change to how entrepreneurship is studied. Presenting the most salient findings and themes in current literature, A Research Agenda for Entrepreneurship and Innovation is essential for researchers in innovation, as well as policy makers at both the local and national levels influenced by the increasing importance of entrepreneurship and innovation.

Handbook of Analytical Techniques for Forensic Samples: Current and Emerging Developments discusses in detail the current trends and latest analytical techniques and methods commonly employed in forensic analysis in order to ensure the proper facilitation of justice. This book is useful for readers who wish to stay updated on the latest trends in the forensic analysis of samples encountered at crime scenes. Technological advancements, such as biosensors, nanotechnology, and taggant technology have upped the level of analysis in forensic science. These emergent technologies, incorporated with existing analytical techniques, are leading to more precise, accurate, and specific examination of forensic samples. Lab-on-a-chip technology has also eased several kinds of on-site analyses done by investigating teams at different types of crime scenes. This book covers the evolution of forensic sample analysis as well as these emerging trends and new technologies.
