Angular Momentum

Angular Momentum is a company enthused about for their creativity and innovative design. The line is extensive, with many models from which to choose. The more sophisticated the model and its capacities, the more expensive its price. There are watches designed with the primary consideration being aesthetics, while others are more about function. For example, if you dive, you may prefer a model able to withstand major depth. Regardless of which model you choose, you are sure to be pleased and refreshed by the unique function and display of Angular Momentum timepieces.

Angular Momentum watches represent a new and exciting concept in watch making. In fact, not only do angular momentum watches function uniquely, but the time is read in a different manner. The term "angular momentum" basically refers to the revolving disk system used to display the time. The hour hand is not included on the face. Rather, the hour is read by what part of the face is at the proper place.

An analysis by Doroshkevich (1970) which shows that the angular momentum of galaxies grew to first order (in proportion to t) during the linear phases of protogalactic evolution is expanded. This result is confirmed in N-body simulations of the formation of structure. The well-known study of Peebles (1969) found growth at second order only (in proportion to t to the 5/3-power) because its analysis was restricted to spherical regions. In such regions growth occurs purely as a result of convective effects on the bounding surface; the material initially within a spherical volume gains no angular momentum in second-order perturbation theory. These considerations do not affect estimates of the total angular momentum acquired by a galaxy in the gravitational instability picture.

The present status of the quasi-local mass-energy-momentum and angular momentum constructions in general relativity is reviewed. First the general ideas, concepts and strategies as well as the necessary tools to construct and analyze the quasi-local quantities are recalled. Then the various specific constructions and their properties (both successes and defects) are discussed. Finally, some of the (actual and potential) applications of the quasi-local concepts and specific constructions are briefly mentioned. This review is based on the talks given at the Erwin Schrödinger Institut, Vienna, in July 1997, at the Universität Tübingen, in May 1998 and at the National Center for Theoretical Sciences in Hsinchu and at the National Central University, Chungli, Taiwan, in July 2000.

An example of angular momentum and its conservation is given in Kepler's second law. This law states that for a planet orbiting the sun, a line from the planet to the sun sweeps across equal areas in equal times. In an elliptical orbit, as the planet moves further from the sun, it ... moves slower in its orbit. The line from the Sun to the planet covers as much area when the planet moves a short distance between two points in the apogee (the most distant portion) of the ellipse as when the planet moves a greater distance at the perigee (the closest portion) of the ellipse.
