Demolition

Demolition is the tearing-down of buildings and other structures. Demolition contrasts with deconstruction, which involves taking a building apart while carefully preserving valuable elements for re-use.

For small buildings, such as houses, that are only two or three stories high, demolition is a rather simple process. The building is pulled down either manually or mechanically using large hydraulic equipment: elevated work platforms, cranes, excavators or bulldozers. Larger buildings may require the use of a wrecking ball, a heavy weight on a cable that is swung by a crane into the side of the buildings. Wrecking balls are especially effective against masonry, but are less easily controlled and often less efficient than other methods. Newer methods may use rotational hydraulic shears and silenced rock-breakers attached to excavators to cut or break through wood, steel, and concrete. The use of shears is especially common when flame cutting would be dangerous.

The tallest planned demolition of a building was the 47-story Singer Building in New York City, which was built in 1908 and torn down in 1967–1968 to be replaced by One Liberty Plaza.

Originality

Originality is the aspect of created or invented works by as being new or novel, and thus can be distinguished from reproductions, clones, forgeries, or derivative works. An original work is one not received from others nor one copied from or based upon the work of others.. It is a work created with a unique style and substance. The term "originality" is often applied as a compliment to the creativity of artists, writers, and thinkers. The idea of originality as we know it was invented by Romanticism, with a notion that is often called romantic originality.

The concept of originality is culturally contingent. It became an ideal in Western culture starting from the 18th century. In contrast, at the time of Shakespeare it was common to appreciate more the similarity with an admired classical work, and Shakespeare himself avoided "unnecessary invention".

Originality in law

In law, originality has become an important legal concept with respect to intellectual property, where creativity and invention have manifest as copyrightable works. In the patent law of the United States and most other countries, only original inventions are subject to protection. In addition to being original, inventions submitted for a patent must also be useful and nonobvious.

Cinderella

Cinderella, or The Little Glass Slipper, (French: Cendrillon, ou La petite Pantoufle de Verre, Italian: Cenerentola, German: Aschenputtel) is a folk tale embodying a myth-element of unjust oppression/triumphant reward. Thousands of variants are known throughout the world. The title character is a young woman living in unfortunate circumstances that are suddenly changed to remarkable fortune. The oldest documented version comes from China, and the oldest European version from Italy. The most popular version was first published by Charles Perrault in Histoires ou contes du temps passé in 1697, and later by the Brothers Grimm in their folk tale collection Grimms' Fairy Tales.

Although the story's title and main character's name change in different languages, in English-language folklore "Cinderella" is the archetypal name. The word "Cinderella" has, by analogy, come to mean one whose attributes were unrecognized, or one who unexpectedly achieves recognition or success after a period of obscurity and neglect. The still-popular story of "Cinderella" continues to influence popular culture internationally, lending plot elements, allusions, and tropes to a wide variety of media.
