The book describes the Copernican Revolution, initiated by the publication of On the Revolution of the Heavenly Spheres by Copernicus until it was accepted by the Scientific Community. The book follows the dramatic turns of the plot of the struggle for scientific truth, along with the conflict between the church and Galileo. Finally, the book brings the modern proofs for the Copernican model, including the very recent discoveries of extra-solar planets.

The book accompanies the reader on a journey of discovery from the planets of our solar system to stars and distant solar systems in the Milky Way, our home galaxy, and beyond to the ends of the universe. A user-friendly introduction to astrophysics, the physics of stars and planets, accompanied by over a hundred illustrations, the book explains concepts, distances and phenomena from other worlds, very different from our everyday experience. Along its journey through the universe the book introduces the science of astrobiology: looking for biological life in space. It also accompanies the course "Astrobiology and Life in the Universe" presented by the author and recorded for the public in the "Cornerstones" program of the Hebrew University. The book deals with topics that have received widespread media coverage in recent years, such as NASA's research missions to Mars and NASA's Kepler and James Web space telescopes. While the Kepler mission led in 2010-2015 to a breakthrough in discovering numerous worlds suitable for life outside the Solar System, James Web, whose launch is expected in 2021, will provide humanity for the first time the ability to detect signs of life in these worlds.

In 1915 Albert Einstein started writing this booklet in an attempt to provide readers who do not necessarily possess knowledge of theoretical physics with an accurate understanding of one of the highest intellectual achievements of the human mind, the theory of the relativity. This friendly brain-challenge is written in the form of a dynamic dialogue, yet it also requires a substantial intellectual effort from the reader. In this important scientific document, the reader is taken on a journey through Einstein’s special and general relativity theories.

The fourth book in the series of Understanding Physics describes three important topics. Fluids – which include both liquids and gases – play a central role in our daily lives. We breathe and drink them, and a rather vital fluid circulates in the human cardiovascular system. The Earth's oceans and atmosphere consist of fluids. Waves – deals with many phenomena like sound waves that carry our messages from our vocal cords to the ears of our friends. Electromagnetic waves carried through optic fibers or through the atmosphere, allow communication with satellites. The book presents: oscillations and harmonic motions, mechanical waves and sound waves. Thermodynamics – heat theory development is one of humankind's most profound intellectual achievements. Understanding thermodynamic principles was fundamental for steam engines that powered the industrial revolution. The book deals with the first law of the thermodynamics, the kinetic theory of gases and the second law of thermodynamics. As in former volumes of Understanding Physics – this book contains clear explanations from basics phenomena to complicated models. It allows readers to examine their understanding by reading exercises and examples. Many figures, diagrams and photos facilitate discovery with this book and convert the experience of learning into a vivid and plausible encounter. The book is based on Fundamental of Physics by David Halliday, Robert Resnick and Jearl Walker.

Magnetism and Optics is a second book in the series of three. This book is built on the foundations of the 6th Edition of Halliday, Resnick, and Walker’s Fundamentals of Physics. One of primary goals of this book is to help students make sense of the physics they are learning. We cannot achieve this goal if students see physics as a set of disconnected mathematical equations that each apply only to a small number of specific situations. We stress conceptual and qualitative understanding and continually make connections between mathematical equations and conceptual ideas. We also try to build on ideas that students can be expected to already understand, based on the resources they bring from everyday experiences. This text is designed to work with learning strategies such as microcomputer-based labs and interactive lectures that are increasingly being used in physics instruction.

This is not an updated edition! Because of the many topics that appear in this book, it was decided to split the book into two parts, make corrections and more. You can now purchase the Second Edition: Understanding physics-mechanics I (earlier chapters from the first edition + corrections + chapter summaries) Understanding physics mechanics II (later chapters from the first edition + new chapter + corrections + chapter summaries).

The ideal gift for all science lovers. This beautifully designed book features a significant number of previously unreleased documents and photographs from the Albert Einstein Archives and links them together with short introductions to chapters about Einstein’s private life, his scientific achievements and his political activities. The new volume represents a substantially enlarged English edition of a title originally published as a version to supplement the permanent exhibition on Albert Einstein at the Jewish National and University Library,
