Explaining Gravity

Explaining Primary Science

Successful science teaching in primary schools requires a careful understanding of key scientific knowledge. This book covers all the major areas of science relevant for beginning primary school teachers, explaining key concepts from the ground up, helping trainees develop into confident science educators. This new edition comes with: · New guidance on teaching primary science today · Activities to enhance your understanding of key teaching topics · Links to national curricula for England, Scotland, Australia and New Zealand · Videos of useful science experiments and demonstrations for the primary classroom

Prior to 20th century physics it was believed an ethereal medium pervaded all space. It was believed the ether is necessary to explain light as waves propagating through a medium. Physicists failed to confirm the ether really exists. Only indirect inference to wave properties can be made with regard to its possible existence. Otherwise it is invisible to our world. Ethereal physics has been abandoned. It has been replaced with a methodology whereby only what can be observed is considered real. All observable effects are mathematically related in the form of a functional theory. Much of theory is postulated, not explained. There is, for instance, no attempt to explain the probability nature of quantum mechanics. Only the results are considered pertinent to scientific investigation. However, with the historical foundation from which modern theory evolves, physicists are becoming confused. They believe, for instance, general relativity predicts black holes. There are no black holes. They are myths created from inconsistent interpretation of theory. This book goes beyond physics to explain the physics of gravity, the atomic structure and cosmology. It provides a historical perspective for understanding physics in a more consistent manner.

Explaining Science's Success

Paul Feyeraband famously asked, what's so great about science? One answer is that it has been surprisingly successful in getting things right about the natural world, more successful than non-scientific or pre-scientific systems, religion or philosophy. Science has been able to formulate theories that have successfully predicted novel observations. It has produced theories about parts of reality that were not observable or accessible at the time those theories were first advanced, but the claims about those inaccessible areas have since turned out to be true. And science has, on occasion, advanced on more or less a priori grounds theories that subsequently turned out to be highly empirically successful. In this book the philosopher of science, John Wright delves deep into science's methodology to offer an explanation for this remarkable success story.
