Visual Astronomy introduces the basics of observational astronomy, a fundamentally limitless opportunity to learn about the universe with your unaided eyes or with tools such as binoculars, telescopes, or cameras. The book explains the essentials of time a
Focusing on the fundamental properties of sound, this book introduces essential concepts such as sound wave characteristics, intensity versus loudness, and frequency versus pitch. It explores how sound waves propagate and interact with different objects and structures. Key topics like standing waves, harmonics, and resonance are presented in an accessible manner, complemented by graphics that enhance visual understanding. Designed for a general audience and non-science majors, it provides a clear foundation in musical sound and related equipment.
Focusing on observational astronomy, this guide covers essential concepts like time and coordinate systems to enhance night sky observations. It equips readers with the knowledge to identify celestial events and objects visible from their specific locations, utilizing accessible resources. The book emphasizes how an observer's latitude affects the visibility and motion of celestial bodies, providing insights for both Northern and Southern Hemisphere stargazers. This resource is ideal for anyone looking to deepen their understanding of the universe through direct observation.
"The Physics of Sound Waves: Music, Instruments, and Sound Equipment (Second Edition) describes the properties of sound waves as they relate to the production of sound by musical instruments, the perception and interpretation of sound, fast Fourier transform analysis, recording and reproduction of musical sounds, and the quality of sound in both indoor and outdoor environments. With a nontechnical description of the modern musical scale, musical intervals, and what makes combinations of musical tones sound pleasant or unpleasant, this book outlines what affects the perception of loudness and pitch, and other related topics. Sound equipment, such as microphones, amplifiers, mixers and loudspeakers and ways of connecting musical equipment and devices using hardwiring and wireless digital interfaces, including USB, Bluetooth and MIDI. Analysing, synthesizing, recording and storing music are included. The discussion gives special attention to demystifying some of the technical terms and helping the reader understand what the analog and digital specifications of sound equipment mean in terms of performance, quality and value. Graphics and animations are used to explain sound production in strings, percussion and wind instruments, and this knowledge is applied to describe selected instruments, including examples from various cultures. Each chapter has topics for further discussion and concludes with questions and problems. Solutions for all questions and problems as well as a mathematical description of waves are provided in the appendix."--Back cover
