Audio and visual cues facilitate some of our most powerful sensory experiences and embed themselves deeply into our memories and subconscious. Sound and light waves interact with our ears and eyesour biological interpreterscreating a textural experience and relationship with the world around us. This well-researched volume explores the science behind acoustics and optics and the broad application they have to everything from listening to music and watching television to ultrasonic and laser technologies that are crucial to the medical field. -
Common to all matter and its smallest and most fundamental unit, the atom determines the properties of a substance and how it responds to other materials and stimuli. Dividing the atom further reveals several smaller particles whose activity forms the heart of nuclear physics. Readers will discover the structure of the atom as well as the ways in which its electrons, protons, and neutrons facilitate both radioactivity and nuclear reactions, both of which have been crucial to technological advancements since the 20th century. -
This book dramatically explains the constant and epic battle between predator and prey, and the ways each adapts to its position on the food chain. There is an engaging section devoted to our place in the food chain, the environmental responsibilities of being at the top, and the consequences of over-fishing or over-harvesting. -

The tale begins as an investigation into the strange stories of an “Opera ghost,” legendary for scaring performers as they sit alone in their dressing rooms or walk along the building’s labyrinthine corridors. Some even think they’ve seen the ghost in evening clothes moving in the shadows. But it isn’t until the triumphant performance of beautiful soprano Christine Daaé that the Phantom begins his attacks—striking terror in the hearts of everyone in the theater. A story that has captured the imagination for a century, The Phantom of the Opera continues to this day as an unparalleled work of sheer entertainment. -

PROMOThe Principles of Naval Architecture series is the defining reference work and text for naval architecture. This volume contains a completely new presentation of the subject of ship resistance embodying these developments. A major goal in the design of virtually all vessels is to obtain a hull form having low resistance. In achieving this goal, the accurate prediction of resistance for a given hull geometry is essential. Since the publication of the previous edition of PNA important advances have been made in theoretical and computational fluid dynamics accompanied by increased use of such work in ship and offshore structure design. The first section of the book provides basic understanding of the flow phenomena that underlie the resistance encountered by a ship moving in water. The second section contains an introduction to the methods by which that knowledge is applied to the prediction of resistance, including model testing, empirical methods and computational methods. A final section provides guidance to the naval architect in designing a hull form. Design procedures are described for achieving favorable flow and resistance characteristics of the hull and appendages. Examples are given for ships designed for high, medium and low speeds. Design considerations affecting both wave and viscous effects are included. Finally the flow in the stern wake is discussed, an area important for both resistance and propeller performance.
