Science and technology is a topic that encompasses science, technology, and the interactions between the two. Science is a systematic enterprise that builds and organizes knowledge in the form of explanations and predictions about nature and the universe. Technology is the collection of techniques, methods or processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation, or any other consumer demands.

Science may drive technological development, by generating demand for new instruments to address a scientific question, or by illustrating technical possibilities previously unconsidered. In turn, technology may drive scientific investigation, by creating demand for technological improvements that can only be produced through research, and by raising questions about the underlying principles that a new technology relies on.

For the majority of human history, technological improvements were achieved by chance, trial and error, or spontaneous inspiration. When the modern scientific enterprise matured in the Enlightenment, it primarily concerned itself with basic questions of nature. Research and development directed towards immediate technical application is a relatively recent occurrence, arising with the Industrial Revolution and becoming commonplace in the 20th century.

2 years ago,I went to Seoul -the capital of Korea.With surrounding Incheon metropolis and Gyeonggi province, Seoul forms the heart of the Seoul Capital Area. Seoul is ranked as the fourth largest metropolitan economy in the world and is larger than London and Paris.

Strategically situated on the Han River, Seoul's history stretches back over two thousand years, when it was founded in 18 BCE by the people of Baekje, one of the Three Kingdoms of Korea. The city was later designated the capital of Korea under the Joseon dynasty. Seoul is surrounded by a mountainous and hilly landscape, with Bukhan Mountain located on the northern edge of the city. As with its long history, the Seoul Capital Area contains five UNESCO World Heritage Sites: Changdeok Palace, Hwaseong Fortress, Jongmyo Shrine, Namhansanseong and the Royal Tombs of the Joseon Dynasty.More recently, Seoul has been a major site of modern architectural construction – major modern landmarks include the N Seoul Tower, the 63 Building, the Lotte World Tower, the Dongdaemun Design Plaza, Lotte World, Trade Tower, COEX, and the IFC Seoul. Seoul was named the 2010 World Design Capital. As the birthplace of K-popand the Korean Wave, Seoul received over 10 million international visitors in 2014, making it the world's 9th most visited city and 4th largest earner in tourism.This is an interesting destination!
