Movement Definition and 635 Threads

The labour movement or labor movement consists of two main wings: the trade union movement (British English) or labor union movement (American English), also called trade unionism or labor unionism on the one hand, and the political labour movement on the other.

The trade union movement consists of the collective organisation of working people developed to represent and campaign for better working conditions and treatment from their employers and, by the implementation of labour and employment laws, from their governments. The standard unit of organisation is the trade union.The political labour movement in many countries includes a political party that represents the interests of employees, often known as a "labour party" or "workers' party". Many individuals and political groups otherwise considered to represent ruling classes may be part of, and active in, the labour movement.The labour movement developed in response to the depredations of industrial capitalism at about the same time as socialism. However, while the goal of the labour movement is to protect and strengthen the interests of labour within capitalism, the goal of socialism is to replace the capitalist system entirely.

    Subtracting centrifugal acceleration from acceleration caused by movement

    I've been playing around with dead reckoning stuff on an rc plane by attaching a gps, 3 axis gyroscope, and 3 axis accelerometer to the plane. When the plane isn't turning, my algorithm works pretty well however when I enter a turn, the readings get way off. Specifically, the plane appears to...
