What is Movement: Definition and 630 Discussions

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.

    Trillion FPS camera developed at MIT camera can 'watch' the movement of light

    This is nothing short of amazing. MIT figured out a way back in February to view how light 'moves' on, about and through objects. Here is a link: http://www.youtube.com/watch?v=snSIRJ2brEk&feature=related They apparently use multiple staggered high speed cameras to capture the images and...

    Particle Movement: The Importance of Distance and Shape at the Smallest Scale

    For a particle to travel from point A to point B at the smallest scale, is there a distance in which the particle has to teleport since its shape doesn't change. Let's say the distance it travels is 0.0000000001, but the particle still need to travel that distance without it being 0.

    Linear movement detector using magnetic, wire coil and transistors

    Hello, I have cool idea for a device and one hardest part of it is to detect the movement of the object. I think I can use a wire coil, and a small magnet attached to the moving object. When the object passes the wire coil (up or down), there will be small voltage inside the wire coil. It...

    What Causes a Sphere to Rotate on a Ramp with Negligible Friction?

    If I have a sphere at rest on top of a ramp, if friccion is negligible, the only forces acting on it would be gravity and the normal force. Both of these go through it's axis of rotation which would be the spheres center. What would cause the rotation then so τ≠0?

    Movement in curved spacetime via deforming one's body

    Apologies if this is the wrong topic, but I think it's relevant under GR since it involves curved space time and I can't see it applying to Newtonian systems. I found an article about swimming in space by deforming one's body. This should not be possible according to my understanding of...

    Why are Dust Particles Moving in a Specific Direction in a Sunlit Car?

    I am a curious (or perhaps bored!) fellow, and as such I noticed something peculiar recently. I was sitting in a car in a garage. The car was stationary and off, and it was facing the east. The sun was beginning to set in the west and a light shone through the back window shield. In the rays of...

    Universal Rate of Movement = Time
