Anonymity
Formally launched in 2014, ALA’s Center for the Future of Libraries works to identify emerging trends relevant to libraries and the communities they serve, promote futuring and innovation techniques to help librarians and library professionals shape their future, and build connections with experts and innovative thinkers to help libraries address emerging issues.The first volume in a new series presented in partnership with the Center, Anonymity explores the roles and ramifications of this hallmark of technology.In the virtual realm, anonymity means that such bedrock values of librarianship as privacy, free speech, and intellectual freedom coexist uneasily with the proliferation of fake news, sexist and racist sentiments, and repugnant ideologies.As trusted guardians of knowledge, libraries and librarians can fill a growing need for reputable information and open dialog.Macrina, founder and director of the Library Freedom Project and a core contributor to the Tor Project, along with co-author Cooper of The Intercept, discuss apps (Whisper, Secret) and forums (Reddit) that promote anonymity as a central feature, even as so-called true anonymity remains elusive because of pervasive user data tracking.They also examine how anonymous content has become valuable fodder for both news organizations and clickbait websites.Will the rise of anonymity and the vulnerabilities it exposes, especially for governments and businesses, lead to a movement against it? Or have our society and its technology passed the point of no return?Bringing issues and viewpoints from outside the profession into the conversation, this book will encourage libraries to think about anonymity and what it means for the future of our institutions.

Does frictional electricity work with conductors?
Frictional electricity does work with conductors. When two different materials are rubbed together, electrons can be transferred from one material to another, creating a static charge. This static charge can be conducted through a conductor, allowing the flow of electrons. However, the conductivity of the material will affect how easily the charge can flow through the conductor.
-
Is a rail a frictional connection?
Yes, a rail can be considered a frictional connection. When a train moves along the rail, the wheels create friction with the surface of the rail, allowing the train to stay on track and move forward. The friction between the wheels and the rail is essential for the train to maintain traction and control its movement. Therefore, the rail and the train's wheels form a frictional connection that enables the train to operate effectively.
-
Does frictional electricity also work with conductors?
Yes, frictional electricity can also work with conductors. When two conductive materials are rubbed together, electrons can be transferred from one material to the other, creating a build-up of static electricity. This can occur with both insulators and conductors, as the transfer of electrons is not dependent on the material's ability to conduct electricity, but rather on the friction between the materials. Therefore, frictional electricity can work with both conductors and insulators.

What does positive locking power transmission and frictional power transmission mean, as well as positive locking and frictional locking?
Positive locking power transmission refers to a system where the connection between two components is secure and does not allow for any slippage or movement. This ensures that power is efficiently transferred from one component to another without any loss. Frictional power transmission, on the other hand, relies on the friction between two components to transfer power, which can result in some power loss due to slippage. Positive locking refers to a mechanism that securely holds two components together without any chance of movement or disengagement. This ensures a strong and reliable connection between the components. Frictional locking, on the other hand, relies on the friction between two components to hold them together, which may not be as secure or reliable as positive locking.

In which direction does the frictional force act?
The frictional force acts in the direction opposite to the direction of motion or the impending motion of an object. It always opposes the relative motion between two surfaces in contact. This force is responsible for slowing down or stopping the motion of an object.
-
How do you calculate frictional force in physics?
Frictional force can be calculated using the equation: f = μN, where f is the frictional force, μ is the coefficient of friction, and N is the normal force. The coefficient of friction is a measure of the interaction between two surfaces, and the normal force is the force exerted perpendicular to the surface. By multiplying the coefficient of friction by the normal force, you can calculate the frictional force acting between two surfaces.

What does positive locking power transmission and frictional locking power transmission mean, as well as positive locking and frictional locking?
Positive locking power transmission refers to a system where the connection between two components is secure and does not allow for any slipping or movement. This is achieved through mechanisms such as gears or splines that ensure a precise and fixed transfer of power. On the other hand, frictional locking power transmission relies on the friction between two surfaces to transfer power. Positive locking refers to a mechanism that physically prevents movement or disengagement, while frictional locking relies on the resistance generated by friction to maintain the connection between components.
-
Is the frictional force proportional to the normal force?
Yes, the frictional force is proportional to the normal force. This relationship is described by the equation F_friction = μ * F_normal, where μ is the coefficient of friction. The coefficient of friction represents the ratio of the frictional force to the normal force, and it remains constant as long as the surfaces in contact and the conditions remain the same. Therefore, an increase in the normal force will result in a proportional increase in the frictional force.
