An automobile (also motor car or simply car) is a wheeled traveler vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run mostly on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.However, the term is far from precise.

The economics of personal automobile ownership go away from the initial cost of the vehicle and includes repairs, maintenance, fuel, depreciation, the cost of borrowing, parking fees, tire replacement, taxes and insurance.The capability for humans to travel rapidly from place to place has far reaching implications for the nature of our society. People can now live faraway from their workplaces, the design of our cities is determined as much by the need to get vehicles into and out of the city as the nature of the buildings and public spaces within the city.

Abstract art

Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses colour and form in a nonfigurative way.In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, that depicts real forms in a easy or rather reduced way—keeping only an allusion of the original natural subject. Such paintings were often claimed to capture amazing of the depicted objects' absolute intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" keep away from any possible ambiguity.

How do Lenses and frames made?

The Lenses are characteristically made from one of three materials. They comprise glass, plastic (usually acrylic), and polycarbonate. Glass lenses have the finest optical clearness and scratch resistance, but are heavier than plastic or the polycarbonate lenses. They can also shatter or break on impact. The Plastic lenses are lighter than glass lenses, but are more prone to scratching. They do on the other hand, offer more resistance to shattering than glass. The Polycarbonate lenses are even lighter than plastic lenses. They are shatter-resistant (but not indestructible) making them apt for impact protection.
The Frames are normally made from plastic, nylon, a metal or metal alloy. Nylon frames are generally used in sports for the reason that they are light weight and flexible. They are able to twist slightly rather than breaking when pressure is applied to them. This flex can also help out the glasses grip well on the wearer's face. Metal frames are generally more inflexible than nylon frames thus they can be more simply damaged when participating in sporty activities, but this is not to say that they cannot be used for such activities. For the reason that metal frames are more rigid, various models have spring loaded hinges to help them grip the wearer's face better. The end of the ear pieces and the bridge over the nose can be textured or have a rubber or plastic material to hold better. The ends of the ear pieces are generally bent so that they wrap around the ear; on the other hand, some models have straight ear pieces. Oakley, for instance, has straight ear pieces on all their glasses.

A short note on European Space Agency

The European Space Agency (ESA), time-honored in 1975, is an inter-governmental organization committed to exploration of space with currently 16 member states. It has its headquarters are in Paris, France. The ESA has a staff (not including sub-contractors and national space agencies) of about 1,900 with a financial plan of 3 billion euros in 2005.
The ESA's spaceport is the Guiana Space Centre in Kourou, French Guiana, and a site selected because it is near to the equator from which commercially essential orbits are easier to access. During the period of Ariane 4 ESA gained the place of market leader in commercial space launches and in current years ESA has time-honored itself as the major competitor of NASA in space exploration.
