Politics is the method by which groups make decisions. It is the solid allocation of values. Although the term is usually applied to performance within governments, politics is observed in all human group relations, as well as corporate, academic, and religious institutions.

In its most basic form, politics consists of "social affairs involving authority or power". In practice, the term refers to the rule and government of a nation-state and to the methods and plans used to formulate and apply government policy.

In a broader sense, any circumstances involving power, or any maneouvring in arrange to improve one's power or status within a group, may be described as politics. This form of politics "is most connected with a struggle for superiority among groups having different priorities and power relations”.

The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a mass of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is close to 5,785 kelvins (1/2350th of the core)). Through most of the Sun's life, energy is formed by nuclear fusion through a series of steps called the p-p (proton-proton) chain; this process converts hydrogen into helium. The core is the only spot in the Sun that produces an substantial amount of heat via fusion: the rest of the star is heated by energy that is transferred outward from the core. All of the energy formed by fusion in the core must travel through many consecutive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

Tools for Shining Your Web Pages

FoldSpy is a graphical tool to respond the very easy question- which part of your web page is fold over i.e. able to be seen without scrolling. Since you know, this is a query without a compact answer, because different users use different browsers and screen resolutions, run different toolbars, and so on. After entered in the service, you insert a single line of javascript in your page header and then open your web page using a #foldspy anchor. You will see a status bar and gradient overlay to demonstrate what percentage of users can see the each part of the web page.

YSlow come up to the Yahoo’s Developer Network. This is attached to the Firebug plug-in for Firefox inform you why your web pages are slow. It examines the whole thing from the size of components to gzipped, ETags be configured, and JavaScript is well minified, and then provide you a report with suggestion for improving performance. Not every suggestion will be relevant to every site, but if you select and choose you can get areas wherever a small work will result in a big improvement.

Robotics is the science and technology of robots, their design, manufacture, and application.Robotics requires a functioning knowledge of electronics, mechanics, and software. A person working in the field is a roboticist. The word robotics was first used in publish by Isaac Asimov, in his science fiction short story "Runaround" (1941).

Although the exterior and capabilities of robots fluctuate enormously, all robots share the features of a mechanical, movable structure under some form of control. The chain is warped of links, actuators and joints which can allow one or more degrees of freedom. Most contemporary robots use open serial chains in which each link connects the one before to the one after it. These robots are called serial robots and often resemble the human arm. A few robots, such as the Stewart platform, exploit closed parallel kinematic chains. Other structures, such as those that mimic the mechanical structure of humans, different animals and insects, are comparatively rare. However, the development and use of such structures in robots is a dynamic area of research. Robots used as manipulators have an end effector mounted on the last link. This end effector can be anything from a welding mechanism to a mechanical hand used to manipulate the environment.
