Books with author Necia H. Apfel

Provides a firm grasp of the concepts implicit in Einstein's theory of relativity and, through easy demonstrations, encourages creative ways to use this theory

Describes how nebulae or clouds of dust particles and gases in space form from the residue of dying stars and how some nebulae contain matter from which stars are born.

A concise text, diagrams, and spectacular full-color photographs illustrate fascinating aspects of Orion, including the many discoveries scientists have made about the celestial bodies within the constellation and the historical myths it has inspired.

An account of the Voyager spacecraft, which visited Jupiter, Saturn, Uranus, and Neptune, describes new observations of the planet's rings, surface textures, and weather conditions

Traces the search leading to the discovery of the smallest bits of matter, pieces too small to be subdivided, and discusses recent developments in the field of particle physics, or study of the invisible microworld of elementary particles.

Discusses the basic principles of relativity and uses "thought experiments" to explain concepts such as the relationship between space and time, gravitation and acceleration, and the curvature of space.

Traces the search leading to the discovery of the smallest bits of matter, pieces too small to be subdivided, and discusses recent developments in the field of particle physics, or study of the invisible microworld of elementary particles.

Explains the phenomena of nebulae--huge clouds in space where some stars form or the glowing cloudlike remnants left by exploding stars--with illustrations and spectacular full-color photographs

Answers questions about the birth and death of stars, how stars radiate light and heat, how galaxies are formed, and how stars are identified, and relates contemporary theory to the sun

An account of the Voyager spacecraft, which visited Jupiter, Saturn, Uranus, and Neptune, describes new observations of the planet's rings, surface textures, and weather conditions

Discusses a number of calendars since time began, which were developed by cultures as they discovered patterns in nature.
