Dynamics

Every object experiences some form of motion which is the result of different forces acting on the object. Dynamics is the study of the forces which are responsible for this motion. Dynamics (from Greek δυναμικός dynamikos "powerful", from δύναμις dynamis "power") may refer to:

Rigid body dynamics

Rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces. The assumption that the bodies are rigid, which means that they do not deform under the action of applied forces, simplifies the analysis by reducing the parameters that describe the configuration of the system to the translation and rotation of reference frames attached to each body. This excludes bodies that display fluid highly elastic, and plastic behavior.

The dynamics of a rigid body system is described by the laws of kinematics and by the application of Newton's second law (kinetics) or their derivative form Lagrangian mechanics. The solution of these equations of motion provides a description of the position, the motion and the acceleration of the individual components of the system and overall the system itself, as a function of time. The formulation and solution of rigid body dynamics is an important tool in the computer simulation of mechanical systems.

Dynamic (record label)

Dynamic is an Italian independent record label located in Genoa. Founded in 1978, it specialises in classical music and opera, especially rarely performed works and has produced several world premiere recordings. The Dynamic catalogue contains over 400 titles, with about 25 new titles added each year and is distributed in 32 countries.

History

Dynamic was founded in 1978 by Pietro Mosetti Casaretto and his wife Marisa. Mosetti Casaretto, a surgeon and amateur violinist, took over a small label founded by the musicologist Edward Neill. In the beginning, Dynamic was a small family business. Mosetti Casaretto and his wife recorded in local churches, oratories and villas. The first recordings were issued on vinyl, the very first one being Paganini's Barucabà Variations played by Salvatore Accardo.

In 1985 the company moved to its current site in the Villa Quartana on the Righi hill overlooking Genoa, where it set up a recording hall that could house a small chamber orchestra. In the late 1990s Mosetti Casaretto retired, and management of the label was taken over by his son-in-law, Alberto Dellepiane. Over the years, the label's focus on chamber music and particularly violin music has widened to include full-length opera recordings on both CD and DVD. More recently, Dynamic has become a high definition content producer for television and cinema.

Stolen!

Stolen! was a mobile game released as a closed beta in November 2015 for iOS, in January 2016 the game quickly gained popularity on Twitter and the internet in general. The goal of the game was to buy Twitter accounts and collect money from those accounts. If another person owned a Twitter account, the player could "steal" it from the person. The only way to play the game was to have a access code, either from another player or from the developers themselves. The game's servers were taken offline on January 14, 2016, and the game was removed from the App Store, due to concerns about the game's potential to be used for harassment. An Android version was being tested prior to the cancellation of the app.

Criticism

Shortly after the large rise in popularity during January 2016, several news outlets, including The Mary Sue and Gadgette published articles raising concern over the ability to use the mechanics of Stolen!, like the ability to edit the profiles of people you have 'Stolen' to harass other people, as well as having to opt-out instead of opt-in to having their profiles in the app. Congresswoman Katherine Clark sent a letter to both Apple and Twitter, urging them to strip the app developers from access to the App Store and Twitter API respectively. The developers have not stated whether Clark's actions were the reason they voluntarily took down the app.

Stolen (play)

Stolen is a play by Australian playwright Jane Harrison. It is based upon the lives of five indigenous people who dealt with the issues for forceful removal by the Australian government.

Plot

Stolen tells the story of five Aboriginal children, who go by the names of Sandy, Ruby, Jimmy, Anne, and Shirley.

Sandy has spent his entire life on the run, never having a set home to live in. Stolen tracks his quest for a place to be, a place where he doesn’t have to keep hiding from the government (even though they are no longer after him), and a place he can call home.

Ruby was forced to work as a domestic from a young age, and was driven insane by the abuse of her white masters. In the latter part of the play, she spends a lot of her time mumbling to herself, whilst her family desperately try to help her.

Jimmy was separated from his mother at a very young age, and she spent her entire life looking for him. He spent a lot of time in prison, and on the day he finally got out, he was told about his mother’s search. As he went to meet her, she died, and he committed suicide in anger. Jimmy was led to believe that his mother was deceased as any letters written to him were taken away by the institution.
