This text provides an account of various experiments, that demonstrate a simplified reality where space and time are relegated to their proper source – the observer. The principles of these experiments and theories originate from the ideas of Einstein, and this text aims to present this 'new' outlook without the need for extensive knowledge of mathematics, physics, or philosophy. This text will be of considerable use to those with a keen interest in physics, and would make for a great addition to any bookshelf. The chapters of this book include: 'The Fitzgerald Contraction', 'Relativity', 'The World of Four Dimensions', 'Fields of Force', 'Kinds of Space', 'The New Law of Gravitation and the Old Law', 'Weighing Light', 'Other Tests of The Theory', 'Momentum and Energy', etcetera. We are publishing this antiquarian book now in an affordable, modern edition - complete with a new biography of the author.
