Streaming Music : Practices, Media, Cultures
Streaming Music examines how the Internet has become integrated in contemporary music use, by focusing on streaming as a practice and a technology for music consumption.The backdrop to this enquiry is the digitization of society and culture, where the music industry has undergone profound disruptions, and where music streaming has altered listening modes and meanings of music in everyday life.The objective of Streaming Music is to shed light on what these transformations mean for listeners, by looking at their adaptation in specific cultural contexts, but also by considering how online music platforms and streaming services guide music listeners in specific ways.Drawing on case studies from Moscow and Stockholm, and providing analysis of Spotify, VK and YouTube as popular but distinct sites for music, Streaming Music discusses, through a qualitative, cross-cultural, study, questions around music and value, music sharing, modes of engaging with music, and the way that contemporary music listening is increasingly part of mobile, automated and computational processes.Offering a nuanced perspective on these issues, it adds to research about music and digital media, shedding new light on music cultures as they appear today.As such, this volume will appeal to scholars of media, sociology and music with interests in digital technologies.

What is electromagnetic induction?
Electromagnetic induction is the process by which a changing magnetic field induces an electric current in a conductor. This phenomenon was discovered by Michael Faraday in the 19th century and is the principle behind the operation of generators, transformers, and inductors. When a magnetic field around a conductor changes, it creates an electric field that causes electrons to move, generating an electric current.

What is electromagnetic pollution?
Electromagnetic pollution refers to the presence of electromagnetic fields in the environment that are caused by man-made sources such as power lines, electrical appliances, and wireless devices. These fields can have negative effects on human health and the environment, leading to concerns about potential risks such as cancer, neurological disorders, and disruptions to wildlife. Electromagnetic pollution is a growing concern as our reliance on technology increases, and efforts are being made to better understand and mitigate its impacts.

What is electromagnetic radiation?
Electromagnetic radiation is a form of energy that is all around us and includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. It consists of oscillating electric and magnetic fields that travel through space at the speed of light. This type of radiation can be emitted by various sources, such as the sun, light bulbs, and electronic devices, and plays a crucial role in many aspects of our daily lives, including communication, heating, and medical imaging.
-
What are electromagnetic inventions?
Electromagnetic inventions are devices or technologies that utilize the principles of electromagnetism to function. These inventions often involve the generation, transmission, and reception of electromagnetic waves or the manipulation of magnetic fields. Examples of electromagnetic inventions include electric motors, generators, transformers, radios, televisions, and various communication devices such as cell phones and Wi-Fi routers. These inventions have revolutionized the way we live and communicate, and continue to play a crucial role in modern technology.

Electromagnetic Radiation
Electromagnetic Radiation is a graduate level book on classical electrodynamics with a strong emphasis on radiation.This book is meant to quickly and efficiently introduce students to the electromagnetic radiation science essential to a practicing physicist.While a major focus is on light and its interactions, topics in radio frequency radiation, x-rays, and beyond are also treated.Special emphasis is placed on applications, with many exercises and problems.The format of the book is designed to convey the basic concepts in a mathematically rigorous manner, but with detailed derivations routinely relegated to the accompanying side notes or end of chapter "Discussions". The book is composed of four parts: Part I is a review of basic E&M (electricity and magnetism), and presents a concise review of topics covered in the subject.Part II addresses the origins of radiation in terms of time variations of charge and current densities within the source, and presents Jefimenko's field equations as derived from retarded potentials.Part III introduces special relativity and its deep connection to Maxwell's equations, together with an introduction to relativistic field theory, as well as the relativistic treatment of radiation from an arbitrarily accelerating charge.A highlight of this part is a chapter on the still partially unresolved problem of radiation reaction on an accelerating charge.Part IV treats the practical problems of electromagnetic radiation interacting with matter, with chapters on energy transport, scattering, diffraction and finally an illuminating, application-oriented treatment of fields in confined environments.

Firesign : The Electromagnetic History of Everything as Told on Nine Comedy Albums
A cultural clearinghouse of the American 1960s and '70s told through the story of the period's most important forgotten comedy group. This expansive book reclaims the Firesign Theatre (hazily remembered as a comedy act for stoners) as critically engaged artists working in the heart of the culture industry at a time of massive social and technological change.At the intersection of popular music, sound and media studies, cultural history, and avant-garde literature, Jeremy Braddock explores how this inventive group made the lowbrow comedy album a medium for registering the contradictions and collapse of the counterculture, and traces their legacies in hip-hop turntablism, computer hacking, and participatory fan culture. He deploys a vast range of material sources, drawing on numerous interviews and writing in tune with the group's obsessive and ludic reflections—on multitrack recording, radio, television, cinema, early artificial intelligence, and more—to focus on Firesign's work in Los Angeles from 1967 to 1975.This ebullient act of media archaeology reveals Firesign Theatre as authors of a comic utopian pessimism that will inspire twenty-first-century recording arts and urge us to engage the massive technological changes of our own era.

How do electromagnetic brakes work?
Electromagnetic brakes work by using the force of electromagnetism to generate braking force. When the brake is engaged, an electric current is passed through a coil, creating a magnetic field. This magnetic field then interacts with a conductive disc or drum, inducing eddy currents that create a braking force. The strength of the magnetic field and the amount of current passing through the coil can be adjusted to control the braking force, making electromagnetic brakes a versatile and efficient braking system.

Does electromagnetic radiation hinder growth?
There is evidence to suggest that prolonged exposure to certain types of electromagnetic radiation, such as that from cell phones and Wi-Fi, may have negative effects on plant growth. Studies have shown that plants exposed to these types of radiation can exhibit stunted growth, reduced chlorophyll content, and altered gene expression. However, more research is needed to fully understand the extent of the impact of electromagnetic radiation on plant growth and to determine if these effects also apply to other forms of life.

What is EMR (electromagnetic remapping)?
EMR, or electromagnetic remapping, is a process used in the field of geophysics to map the subsurface structure of the Earth. It involves measuring the variations in the Earth's natural electromagnetic field caused by changes in the conductivity of the subsurface materials. By analyzing these variations, geophysicists can create detailed images of the subsurface, helping to identify potential mineral deposits, groundwater resources, or geological structures. EMR is a non-invasive and cost-effective method that can provide valuable insights for various industries, including mining, environmental studies, and geotechnical engineering.

Can electromagnetic waves be transformed?
Yes, electromagnetic waves can be transformed. This can be done through processes such as reflection, refraction, diffraction, and absorption. For example, when electromagnetic waves hit a smooth surface, they can be reflected, changing their direction. When they pass through different mediums, such as air to glass, they can be refracted, changing their speed and direction. These transformations are fundamental to how electromagnetic waves interact with and travel through the world around us.
