Neptune

Neptune (pronounced /'n?ptju? n/[8]) is the eighth and farthest planet from the Sun in the Solar System. It is the fourth largest planet by diameter, and the third major by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 Earth masses and less dense. The planet is named following the Roman god of the sea. Its astronomical symbol is a stylized story of Poseidon's trident.

Discovered on September 23, 1846, Neptune was the first planet found by mathematical prediction quite than regular observation. Unexpected changes in the orbit of Uranus led astronomers to realize the gravitational perturbation of an unknown planet. Neptune was found within a degree of the predict position. The moon Triton was found shortly thereafter, but none of the planet's other 12 moons were discovered preceding to the twentieth century. Neptune has been visit by only one spacecraft, Voyager 2, which flew by the planet on August 25, 1989.

Building

Buildings provide numerous needs of society. The human body can be continued and may effectively function only within a limited range of climatic conditions such as temperature, humidity, moisture, sunlight, and amount of oxygen and pollutants in the air. Along with access to food and drinking water, the need to make places that are protected from the outdoors and where one can happily live, work, eat, sleep, have children or engage in leisurely activities has always been a top concern for humans.

A building as a security represents a physical division of the human habitat into the inside (a place of comfort and safety) and the outside (a place that at times may be harsh and harmful). Humans have a strange drive to reproduce on their lives and express themselves through art. Ever since the first cave paintings, the buildings and everything on, inside and near buildings have become objects of creative expression. In recent years, attention on sustainable planning and building practices has improved in the U.S.

Climate

The climate is commonly measured to be the weather averaged over a long period of time, naturally 30 years. Somewhat more precisely, the concept of "climate" also includes the statistics of the weather — such as the degree of day-to-day or year-to-year difference expected. IPCC is called as Intergovernmental Panel on Climate Change.
Climate in a narrow sense is usually defined as the “average weather”, or more meticulously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time range from months to thousands or millions of years. The traditional period is 30 years, as defined by the World Meteorological Organization (WMO). These quantities are the majority often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a numerical description, of the climate system.
