Within Grasp

How do we learn? And how can we learn better? In this groundbreaking look at the science of learning, Sanjay Sarma, head of Open Learning at MIT, shows how we can harness this knowledge to discover our true potential. Drawing from his own experience as an educator as well as the work of researchers and innovators at MIT and beyond, in Grasp, Sarma explores the history of modern education, tracing the way in which traditional classroom methods—lecture, homework, test, repeat—became the norm and showing why things needs to change. The book takes readers across multiple frontiers, from fundamental neuroscience to cognitive psychology and beyond, as it considers the future of learning. It introduces scientists who study forgetting, exposing it not as a simple failure of memory but as a critical weapon in our learning arsenal. It examines the role curiosity plays in promoting a state of “readiness to learn” in the brain (and its troublesome twin, “unreadiness to learn”). And it reveals how such ideas are being put into practice in the real world, such as at unorthodox new programs like Ad Astra, located on the SpaceX campus. Along the way, Grasp debunks long-held views such as the noxious idea of “learning styles,” equipping readers with practical tools for absorbing and retaining information across a lifetime of learning.

An important, hopeful book that looks at the urgent problem of childhood malnutrition worldwide and the revolutionary progress being made to end it. A healthy Earth requires healthy children. Yet nearly one-fourth of the world’s children are stunted physically and mentally due to a lack of food or nutrients. These children do not die but endure a lifetime of diminished potential. During the past thirty years, says Sharman Russell, we have seen a revolution in how we treat these sick children and in how—with a new understanding of the human body and approach to nutrition, and new ways to reach out to hungry mothers and babies—we have gone from unwittingly killing severely malnourished children to bringing them back to health through the “miracle” of ready-to-eat therapeutic food. Intertwined with stories of scientists and nutrition experts on the front lines of finding ways to end malnutrition for good, Russell writes of her travels to Malawi, one of the poorest and least-developed countries in the world and also the site of pathbreaking, cutting-edge research into childhood malnutrition. (Eighty percent of Malawians are farmers subsisting on less than an acre of land and coping with erratic weather patterns due to global warming; fifty percent live below the poverty line; and forty-two percent of Malawi’s children are affected by a lack of food or nutrients.) As she writes of her personal exploration of new friendships and insights in a country known as “the warm heart of Africa,” Russell describes the programs that are working best to reduce childhood stunting and explores how malnutrition in children is connected to climate change, how vitamins and minerals are preventing these harmful effects, why the empowerment of women is the single most effective factor in eliminating childhood malnutrition, and what the costs of ending childhood malnutrition are. Sharman Russell, much-admired writer of luminous prose and humane heart, whose writing has been called, “elegant” (The Economist) and “extraordinarily well-crafted, far-reaching, and heart-wrenching” (Booklist), winner of the John Burroughs Medal for distinguished natural history writing, has written an illuminating, inspiring book that makes clear the promise of what is today, gratefully, within our grasp.

This volume presents a variety of studies relating to the reach to grasp movement and provides a necessary and valuable contribution to the field of motor control. The professions covered in this book range from those interested in the basic sciences to those more interested in practical application. Neurophysiologists and biomechanists join with therapists and neural modelers to present an extensive overview of current developments. Evolutionary and developmental aspects are included together with descriptions of how this movement is affected by central nervous system damage. Purely theoretical aspects of the motor control of this movement are interspersed with treatment applications and robotics.

Reaching for objects in our surroundings is an everyday activity that most humans perform seamlessly a hundred times a day. It is nonetheless a complex behavior that requires the perception of objects’ features, action selection, movement planning, multi-joint coordination, force regulation, and the integration of all of these properties during the actions themselves to meet the successful demands of extremely varied task goals. Even though reach-to-grasp behavior has been studied for decades, it has, in recent years, become a particularly growing area of multidisciplinary research because of its crucial role in activities of daily living and broad range of applications to other fields, including physical rehabilitation, prosthetics, and robotics. This volume brings together novel and exciting research that sheds light into the complex sensory-motor processes involved in the selection and production of reach-to-grasp behaviors. It also offers a unique life-span and multidisciplinary perspective on the development and multiple processes involved in the formation of reach-to-grasp. It covers recent and exciting discoveries from the fields of developmental psychology and learning sciences, neurophysiology and brain sciences, movement sciences, and the dynamic field of developmental robotics, which has become a very active applied field relying on biologically inspired models. This volume is a rich and valuable resource for students and professionals in all of these research fields, as well as cognitive sciences, rehabilitation, and other applied sciences.

This book investigates new important applications of the Spatial Grasp Technology (SGT) allowing us to effectively simulate and manage large distributed dynamic systems on semantic and holistic levels. This patented technology, developed for decades and in different countries, is based on a completely different philosophy and model allowing us to directly operate in united distributed physical and virtual spaces and provide system solutions much simpler and more compact than under other approaches. The described applications include basic operations suitable for solving many network-related problems, simulation of such mysterious concept as consciousness so important for the design of advanced intelligent systems, modelling the spread of viruses and distribution of antivirus vaccine, and also implementation of the latest decision-centric and mosaic-based organizational concepts important for modern defence and industrial systems. The described technology version with its Spatial Grasp Language can be implemented even within university environments, with communicating language interpreter copies, potentially numbering millions to billions, easily embedded into any existing systems, including Internet, thus converting the whole world into a powerful symbiotic simulation management engine. The book is oriented on system scientists, application programmers, industry managers, and also university students interested in advanced M.Sc. and Ph.D. projects related to distributed system management.
