First published in 1925, Bertrand Russell’s ABC of Relativity was considered a masterwork of its time, contributing significantly to the mass popularisation of science. Authoritative and accessible, it provides a remarkable introductory guide to Einstein’s theory of Relativity to a general readership. One of the most definitive reference guides of its kind, and written by one of the twentieth century’s most influential philosophers, ABC of Relativity continues to be as relevant today as it was on first publication.

An exploration of Bertrand Russell's writings during the interwar years, a period when he advocated "the scientific outlook" to insure the survival of humanity in an age of potential self-destruction.

Stem Technology Is A Very Important Topic In Today'S World And This Book Will Allow Students To Learn More About Atoms, Molecules, And How Different Temperatures And Situations Affect Them. It Also Introduces Them To The Periodic Table Of Elements And How Even Today More Elements Are Being Discovered And The Periodic Table Continues To Grow.

At the turn of the 20th century, physics entered into a new world, the invisible silent world of atoms, atomic nuclei and elementary particles. Our twentieth century then produced the theory that has been serving physicists so faithfully for over sixty years -- quantum mechanics. The landscape of the new world is quire unlike our own. So different that phsyicists frequently lack words to describe it. Quantum mechanics had to create new conceptions for the world of the ultrasmall, bizarre conceptions beyond the scope of pictorial imagery. Customary physical laws cease to operate in the new world. Particles lose their dimensions and acquire the properties of waves. Electrons and the other building stones of matter can pass through impenetrable barriers, or they can vanish altogether leaving only photons in their place. Those are the things quantum mechanics dealt with. This book will tell you about the origin and development of quantum mechanics, about its new concepts. It will describe how the new theory deciphered the secrets of the structure of atoms, molecules, crystals, atomic nulei, and how quantum mechanics is dealing with the problem of the most fundamental of all properties of matter --the interaction of particles and the relationships between fields and matter.

This volume contains Russell's reviews of and introductions to other philosophical works including his famous introduction to Wittgenstein's Tractatus Logico-Philosophicus.
