Описание: Ever wonder why steam rises from a bowl of hot soup or why a greenhouse retains heat? And have you ever puzzled over the real meaning of "once in a blue moon" or why sand is darker when it's wet than when it's dry? And just why, exactly, do bubbles appear in a glass of beer when you add salt to it? These and many other baffling questions are answered in this engaging book by a physics professor at Pennsylvania State University. Ranging from playful to serious, Professor Bohren's lively and entertaining discussions employ a liberal mixture of humor and anecdote to debunk a host of scientific myths and render science lessons thoroughly understandable. Chapters include "On a Clear Day You Can't See Forever," "A Murder in Ceylon." "The Green Flash," "Physics on a Manure Heap," " Indoor Rainbows," and "Multiple Scattering at the Breakfast Table." "The book rings with a unifying tone: the science of the everyday physical world is fun. And so is the book," writes Jearl Walker, a member of the Physics Department at Cleveland State University. Beginning physics and general readers will be fascinated by the scientific knowledge gained from this work; and science teachers will find it a treasure trove of ideas for simple, vivid classroom demonstrations.
These vividly recounted tales of human skill and ingenuity offer fascinating views of the correlation between theories, practical inquiries, ideas, and facts. Re-created strictly on the basis of the original publication in which the results were first announced, the scrupulously accurate retellings of 20 groundbreaking scientific experiments are complemented with rare photos and illustrations. Based on such criteria as fame, historical importance, elegance, and economy of method, the experiments include Aristotle's work on the embryology of the chick, Galileo's discovery of the law of descent, Newton's experiment on the nature of colors, Lavoisier's proof of the oxygen hypothesis, William Beaumont's work on the process of digestion, Faraday's demonstration of the identity of all forms of electricity, J. J. Thompson's discovery of the electron, Michelson and Morely's demonstration of the impossibility of detecting the motion of the earth, and a dozen others. Each experiment is appraised and analyzed in the light of subsequent developments, placing the work within the context of the history of science. In addition to diagrams and photographs of the experimental method and apparatus, brief biographies and portraits of the scientist appear as well. Rom Harre is a Fellow Emeritus of Linacre College, Oxford, and an Adjunct Professor at Georgetown University and American University, Washington, D.C.

Описание: "A mathematician named Klein Thought the Moebius band was divine. Said he: 'If you glue The edges of two, You'll get a weird bottle like mine.' " -- Stephen Barr In this lively book, the classic in its field, a master of recreational topology invites readers to venture into such tantalizing topological realms as continuity and connectedness via the Klein bottle and the Moebius strip. Beginning with a definition of topology and a discussion of Euler's theorem, Mr. Barr brings wit and clarity to these topics: New Surfaces (Orientability, Dimension, The Klein Bottle, etc.) The Shortest Moebius Strip The Conical Moebius Strip The Klein Bottle The Projective Plane (Symmetry) Map Coloring Networks (Koenigsberg Bridges, Betti Numbers, Knots) The Trial of the Punctured Torus Continuity and Discreteness ("Next Number," Continuity, Neighborhoods, Limit Points) Sets (Valid or Merely True? Venn Diagrams, Open and Closed Sets, Transformations, Mapping, Homotopy) With this book and a square sheet of paper, the reader can make paper Klein bottles, step by step; then, by intersecting or cutting the bottle, make Moebius strips. Conical Moebius strips, projective planes, the principle of map coloring, the classic problem of the Koenigsberg bridges, and many more aspects of topology are carefully and concisely illuminated by the author's informal and entertaining approach. Now in this inexpensive paperback edition, Experiments in Topology belongs in the library of any math enthusiast with a taste for brainteasing adventures in the byways of mathematics.

Описание: Join Elmo, Super Grover 2.0, and the rest of the gang to learn about science Kids will be captivated by the playful illustrations and wealth of information as their favorite characters lead them through numbered steps of simple at-home experiments, including making a tabletop volcano and an indoor rainstorm. Plus, there are "Murray's Science Words on the Street" sidebars, journal pages, mazes, and more.
Описание: "Informative and engagingly idiosyncratic . . . brings the subject down to earth with offbeat, everyday examples and easy-to-follow experiments. . . . Both professionals and laymen can learn from this book." -- The New York Times Book Review "A brilliant collection of intriguing examples of the physics of everyday phenomena, with the examples presented as puzzles." -- Discover "A delightful book." -- Bulletin of the American Meteorological Society This is the sequel to Craig Bohren's popular Clouds in a Glass of Beer (also available from Dover), the book that made the fascinating world of atmospheric physics accessible to readers without a scientific background. Like its predecessor, this volume abounds in lively writing, fun-filled and easy-to-perform experiments, and numerous photographs and illustrations that offer illuminating and memorable ways to learn about an intriguing branch of science.
Описание: To Martin Gardner, seeing is not just believing -- it is understanding. This fundamental rule has made him one of the most successful teachers and popularizers of science in America. With the simple instructions in this book and a few commonly available household objects, you or your child can easily learn even the most difficult scientific principles by directly experiencing how they work. Gardner shows you how to re-create classic experiments with easily obtainable objects. Using just a flashlight, a pocket mirror, and a bowl of water, you can demonstrate the color composition of white light just as Newton did 300 years ago. With cardboard, colored paper, and wax paper you can perform "Meyer's experiment" with complementary colors. You need only a playing card, a spool, and a thumbtack to demonstrate Bernoulli's principle of aerodynamics. A soda bottle filled with water, a few paper matches, and a toy balloon elucidate Pascal's law governing pressure in liquids. And two drinking glasses, some matches, and a piece of wet blotting paper re-create a famous experiment, first performed in 1650 in Magdeburg, Germany, that dramatically reveals the force of ordinary atmospheric pressure. In language simple enough to be easily understood by an 11-year-old, yet technically accurate and informative enough to benefit adults, and aided by Anthony Ravielli's clear illustrations, Gardner presents a splendid practical course in basic science and mathematics. While your child perplexes and delights his or her friends with a series of 100 amusing tricks and experiments, he or she is learning the principles of astronomy, chemistry, physiology, psychology, general mathematics, topology, probability, geometry, numbers, optics (light), gravity, static electricity, mechanics, air hydraulics, thermodynamics (heat), acoustics (sound), and inertia. This is a perfect refresher course for adults as well as an ideal introduction to science for youngsters. "The experiments ... are all clearly explained and unusually well illustrated." -- Booklist.
