Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past thirty years, scientists have learned that two little-understood components--dark matter and dark energy--comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry--the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable--guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.

Designed by leading experts in the field of science education, this hands-on science workbook provides young learners, in third and fourth grade, the tools they need to become actively involved with science. Science Essentials leads children through the processes of observation and experimentation, prediction and drawing conclusions. It covers all the essential science topics like dinosaurs, animals, birds, insects, the human body, health, nutrition, plants, the solar system, earth, weather, environment, magnets, electricity, and simple machines in an exciting and easy-to-follow way. Games and activities (for learning fun) and a periodic table of the elements poster with stickers of the elements are included. Science Essentials is the most complete book that offers: *Challenging and motivating science investigations. *Hands-on approach to science learning. *Complete direction and examples to encourage independent study. *Vivid, full-color illustrations to spark the learner's inter

Designed to offer non-specialist teachers a wide range of open-ended photocopiable activities for specified levels of ability. This science book is one of a series which will provide support for any scheme of work being used in the school, either as part of structured session or as educationally sound time fillers. It is an introduction to forces and their effects, including gravity and friction, sliding, rolling, falling and bouncing and is designed for children at Key Stage 1 based on the learning requirements of AT1 scientific investigation and AT4 physical processes.
