Music

Music is an art form that involves organized sounds and quiet. It is articulated in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture).

Music may also absorb generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, traditional or religious purposes. The definition of what constitutes music varies according to culture and social context, with assorted interpretations of the term being established under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form


The history of music predates the written word and is tied to the enlargement of each unique human culture. The development of music among humans occurred against the backdrop of natural sounds such as birdsong and the sounds other animals use to communicate. primeval music, once more commonly called primitive music, is the name given to all music created in preliterate cultures (prehistory), beginning somewhere in very late geological history.

Anatomical basics of the human lip

One differentiates between the Upper and lower lip. The lower lip is usually somewhat larger. The border between the lips and the surrounding skin is referred to as the vermilion border, or simply the vermilion. The vertical groove on the upper lip is known as the philtrum.

The skin of the lip, with three to five cellular layers, is very thin compared to typical face skin, having up to 16 layers. With light skin color, the lip skin contains no melanocyte. Because of this, the blood vessels appear through the skin of the lips, which leads to their notable red coloring. With darker skin color this effect is less prominent, as in this case the skin of the lips contains more melanin and thus is visually thicker.

The lip skin is not hairy and does not have sweat glands or sebaceous glands. Therefore, it does not have the usual protection layer of sweat and body oils which keep the skin smooth, kill pathogens, and regulate warmth. For these reasons, the lips dry out faster and become chapped more easily.

Three Gorges Dam

The Three Gorges Dam spans the Yangtze River on Sandouping, Yichang, Hubei region, China. Construction began in 1994. It will be the major hydroelectric dam in the world, more than five times the size of the Hoover Dam. The reservoir began filling on June 1, 2003, and will occupy the current position of the scenic Three Gorges area, between the cities of Yichang, Hubei; and Fuling, Chongqing. Structural work was finished on May 20, 2006, nine months ahead of schedule. However, some generators still have to be installed and the dam is not expected to become fully equipped until 2009.

Three Gorges Dam, downstream side, 26 July 2004As with many dams, there is controversy over the operating cost and benefits of the Three Gorges Dam. Although there are economic profit from flood control and hydroelectric power, there are also concerns concerning the future of over 1.9 million people who will be displaced by the flood waters, the loss of some valuable archaeological and cultural sites, as well as the effects on the environment. It is believed that the dam was a contributing part in the extinction of the Yangtze River Dolphin.

The Real Miracle

As far as Miracles is concern, turning salty seawater in to sweet water is quite amazing. Regardless of the scientific clarification being doled out—surplus freshwater flowing from the Mahim River into the sea—the thousand mass to Mahim Creek near the beachfront in Mumbai will pretty see the ‘transubstantiation’ as the deed of the late Haji Maqdoom Baba, whose shrine is in the area. Mass hysteria, of course, is only a term to clarify the hordes of believers filling plastic bottles and drinking the water. But the real miracle would be if those glugging the ‘miraculous’ water manages to flee succumbing to serious gastric illness.

The water of Mahim Creek, sweetened or otherwise, is dirty and would scandalize not only the likes of Sunita Narain of the Centre for Science and Environment. Maharashtra Chief Minister Vilasrao Deshmukh and officials of the Municipal Corporation of Greater Mumbai have already request to people not to drink the water. Industrial waste is not the finest ingredient for a miracle. But telling this to goggle-eyed people facing even more goggle-eyed TV cameras is as worthwhile as persuasive people that a Ganesh idol sipping milk is caused by suction and not godly lactose tolerance.

Fortunately, rumors of the sweetened water turning back to its original brackish form might stop a future surge. Now we only wait for the real miracle of no one complaining of sickness.
