A. Rey’s passion for astronomy evident on every page.Second edition updates concentrate on the planetary and solar system information in the latter part of the book. Facts and figures for each planet have been revised, and new scientific information has been added, such as Pluto’s reclassification as a dwarf planet.

    Polya's simple, energetic prose and use of clever examples from a wide range of human activities, this two-volume work explores techniques of guessing, inductive reasoning, and reasoning by analogy, and the role they play in the most rigorous of deductive disciplines.

    Additional topics include the mutual action of electric currents, dimensions of electric units, and much more. 1891 edition.

    This vital work is offered in an updated edition, with a new forword by the author.

    A narrative of needle-nosed ships flying at blistering speeds, it is also the moving testament of a man risking his life to push back the frontiers of scientific knowledge. Like St.-Exupry, Bridgeman is capable of describing the vastness and beauty of the skies. But as America's foremost experimental test pilot, he is constantly aware of the multitude of technical information which he is called upon to use at any given instant.After the war, Bill Bridgeman left the Navy a restless man. Seeking action, he joined Douglas Aircraft as an engineering test pilot. Soon he was asked to take over the final stages of the Skyrocket testing program. The Skyrocket, a javelin-shaped experimental ship, was a challenge to Bridgeman. The story of his day-by-day life with the plane is the substance of THE LONELY SKY.

    You cannot be successful or happy without confidence in your own powers and abilities. To succeed you need self-confidence . . . this book will help you to believe in yourself and release your inner powers. ' Norman Vincent Peale in chapter 1. BE WHO YOU WANT TO BE - AND GET THE LIFE YOU WANT TO LIVE This book is a carefully adapted version of The Power of Positive Thinking, one of the most inspiring bestsellers of all time. It aims to help young people to use the power of positive thinking to build successful lives. Dr Peale gets right to the heart of the most common problems faced by teenagers, and offers a series of practical steps for solving them. He provides young people with the positive approach needed to achieve the major goals in life, showing them how to maximise their talent and energies, to give them confidence when they need it most.

    Ranging from simple puzzles and games to more advanced problems, topics include the psychology of lottery players, the arrangement of chromosomes in a human cell, new and larger prime numbers, the fair division of a cake, how to find the shortest possible way to link a dozen locations by rail, and many other absorbing conundrums. A fascinating glimpse into the world of numbers and their uses. 1969 edition. 391 black-and-white illus.

    Here the texts of two of Schr�dinger's most famous lecture series are made available again. In the first, entitled Nature and the Greeks, Schr�dinger offers a historical account of the scientific world picture. In the second, called Science and Humanism, he addresses fundamental questions about the link between scientific and spiritual matters. As Roger Penrose confirms, these are the profound thoughts of a great mind, and as relevant today as when they were first published in the 1950s.

    

    A minimum of mathematics is used for direct explanations of primary cells, magnetism, Ohm's Law, capacitance, transformers, DC generators, and AC motors. Other essential topics covered include conductance, current flow, electromagnetism and meters.

    Russell develops his views about the philosophy of science out of the theories of scientists such as Einstein, Bohr and Heisenberg.

    

    Written with complete lucidity, it is a book not only for astronomers, physicists, and geographers, but also for artists and photographers and for anyone else who would like to know more about how to observe and understand the strange behavior of light and color in nature.The author shows just how, when, and under what conditions to observe the fata morgana (a complex mirage in the form of a city in the sky), the scintillation of stars and planets, apparent motion in shadows and objects due to air currents, color changes due to refraction and reflection, illusions of motion and direction, effects of rapidly moving spokes, the changes in color and light due to eclipses of the sun and moon, magnificent colors on a frozen window pane, or an extended body of water, the deceptive appearance of objects beneath the surface of water, and many other such phenomena.The theory explaining most of these effects is given in ordinary language only occasionally supplemented by elementary mathematical demonstrations. In addition, Professor Minnaert has included 202 illustrations (including 42 photographs) covering practically every phenomenon discussed. These illustrations make hundreds of details explicit so that you can identify them at sight and try the experiments outlined.

    Detailed proofs rigorously worked out. 1929 edition.

    Contributors include Jean Henri Fabre, Donald Culross Peattie, William Beebe, Nobel Laureate Maurice Maeterlinck, Pulitzer Prize-winner Edwin Way Teale, and others.
