Copernicus who was a great founder of modern astronomer as he completed and gave to the world his great work De Revolutionibus, which asserted that the earth rotated on its axis once daily and traveled around the sun once yearly. By this theory, he overthrew the Ptolemaic theory and established that the center of universe is the sun. Einstein, another great scientist in this world, Relativity, The speed of light, Space-time and Black holes were profound theories with difficulty to explain, but we do know that the speed of light is faster then sound, and light cannot escape from the black holes, just because of gravity becoming extremely enormous. Through these theories, people have understood many nature phenomenon of the universe, but there are still many mystic phenomenon which cannot be explained at moment. That is why scientists are unceasingly discovering and searching unknown answers of this world. .
To understand what is the relationship between science and technology is a complicated and confusion process, people are always mixed by the two things. In fact, science and technology are totally different. Let's keep eyes on the definition of them by some first. "Modern science is a body of laws based on systematically assembled knowledge capable of predicting phenomena not observed when the laws are formulated".( text book p19) .
Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts(date). An ultimate purpose of science is to discern the order that exists between and amongst the various facts. What is more, science involves more than the gaining of knowledge. It is the systematic and organized inquiry into the natural world and its phenomena, science is a about gaining a deeper and often useful understanding of the world.
