In this cleverly conceived book, physicist Robert Gilmore makes accessible some complex concepts in quantum mechanics by sending Alice to Quantumland-a whole new Wonderland, smaller than an atom, where each attraction demonstrates a different aspect of quantum theory. Alice unusual encounters, enhanced by illustrations by Gilmore himself, make the Uncertainty Principle, wave functions, the Pauli Principle, and other elusive concepts easier to grasp.

The Old Quantum Theory explains how the classical laws were modified by Planck, Einstein, Rutherford, Bohr, and other contributors to account for atomic phenomena, comprising the development of quantum theory from its start at the very end of the 19th century until the beginning of the 20th century. This book begins by discussing Planck's discovery of his radiation law, followed by Einstein's introduction to quanta. Next is a description of the Rutherford model of the atom and Bohr's postulates, which are confirmed by the Franck-Hertz experiment. This selection concludes with a description of how Bohr's theory could explain the main features of the atomic spectra. A brief summary of other important developments in the period are also elaborated. This publication is beneficial to students and researchers conducting work on the history of quantum mechanics from the 1900s to the development of wave mechanics.

First Snow White encounters one of the Little People, then one of the Even Smaller People, and finally one of the Truly Infinitesimal People. And no matter how diligently she searches, the only dwarves she can find are collapsed stars! Clearly, she's not at home in her well-known Brothers Grimm fairy tale, but instead in a strange new landscape that features quantum behavior, the wavelike properties of particles, and the Uncertainty Principle. She (and we) must have entered, in short, one of the worlds created by Robert Gilmore, physicist and fabulist.

When the destination sign on Scrooges train reads "HEAT DEATH" instead of "HEATHROW," when his dead partner Marleys face appears as a talking head in a department store TV, and when the street lights outside his flat begin acting strangely, it is a sign of a bad night to come. Like his famous ancestor, the modern Scrooge is about to be visited by ghosts. But its not his hard heart that needs opening; its his closed mind. Physicist Robert Gilmore, author of the popular Alice in Quantumland, presents here a delightful takeoff, where the three visitations represent Science Past, Present and Future. For everyone who wants a playful, painless yet surprisingly sophisticated introduction to the ideas of modern physics, this is a brilliant tour de force and a charming read.

Thousands of readers who were delighted by the adventures and science content of Alice in Quantumland are in for another treat. This time physicist Robert Gilmore takes us on a journey with Dorothy, following the yellow building block road through the land of the Wizard of Quarks. Using characters and situations based on the Wizard of Oz story, we learn along the way about the fascinating world of particle physics. Classes of particles, from quarks to leptons are shown in an atomic garden, where atoms and molecules are produced. See how Dorothy, The Tin Geek, and the Cowardly Lion experience the bizarre world of subatomic particles.

"During his comparatively brief life (he died at thirty-nine, the age Mozart was to die) Blaise Pascal devoted his unusual talents to mathematics, physics and religion. His religious views are still widely discussed, and the general interest in this aspect of his life may be responsible for the fact that his mathematical and scientific achievements are less known. Those who are familiar with his Pensées, which are fragments of an intended Apology for Christianity, have had little opportunity of acquiring a just appreciation of the originality of his thought in physics and probability theory. This book fills this gap by describing Pascal’s work in a way that is accessible to anyone interested in his contribution to modern science and his attempt to tame Lady Luck. The words “Unconventional Science” in the subtitle of the book are meant as a reminder of the radically different way of looking at nature that was developed by Pascal and his contemporaries. The first seven chapters examine Pascal’s ingenious experiments to show that a vacuum can be produced, an idea that led him to ascend a mountain with a barometer to prove that we lived submerged under a sea of air. Chapter eight considers his bold views on the advancement of science and religion, and chapter nine his new philosophy of experimental science. The concluding chapters offer an insight into his pioneering work in the theory of probability and his willingness to help a friend who was a keen gambler but no mathematician. Pascal even applied his calculation of the odds at games of chance to the problem of personal destiny and the existence of God. Walking in his footsteps, the reader not only discovers the new world of experimental science but learns to play for high stakes."--Publisher's description.

At least eighty percent of the mass of the universe consists of some material which, unlike ordinary matter, neither emits nor absorbs light. This book collects key papers related to the discovery of this astonishing fact and its profound implications for astrophysics, cosmology, and the physics of elementary particles. The book focuses on the likely possibility that the dark matter is composed of an as yet undiscovered elementary particle, and examines the boundaries of our present knowledge of the properties such a particle must possess.
