Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Contemporary science is typically subdivided into the natural sciences, which study the material universe; the social sciences, which study people and societies; and the formal sciences, such as mathematics. The formal sciences are often excluded as they do not depend on empirical observations.[4]Disciplines which use science like engineering and medicine may also be considered to be applied sciences.[5]
During the Middle Ages in the Middle East, foundations for the scientific method were laid by Alhazen in his Book of Optics.[6][7][8] From classical antiquitythrough the 19th century, science as a type of knowledge was more closely linked to philosophy than it is now and, in fact, in the Western world, the term "natural philosophy" encompassed fields of study that are today associated with science, such as astronomy, medicine, and physics.[9][nb 3] While the classification of the material world by the ancient Indians and Greeks into air, earth, fire and water was more philosophical, medieval Middle Eastern scientists used practical, experimental observation to classify materials.[10]
In the 17th and 18th centuries, scientists increasingly sought to formulate knowledge in terms of laws of nature. Over the course of the 19th century, the word "science" became increasingly associated with the scientific method itself, as a disciplined way to study the natural world. It was in the 19th century that scientific disciplines such as biology, chemistry, and physics reached their modern shapes. The same time period also included the origin of the terms "scientist" and "scientific community," the founding of scientific institutions, and increasing significance of the interactions with society and other aspects of culture.[11][12
Science and technology may be partly responsible for many of the problems that face us today. The problems are the advancement of weapons, bombs, biochemical and nuclear weapon, which brought us violence amongst ourselves and others. Another problem is human dependences on technology, such as the internet, computers, cell phones etc. Yet one of the biggest problems is pollution. Three types of pollution that dominate they are water, air and noise pollution.
Water is one of the several resources that we need most, many people can survive without food for several weeks but they cannot survive without water for less then a week. According to Water Pollution web site “millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes.” The advancement of science and technology causes much water pollution, such as dumping toxic waste into rivers, ponds, oceans, and even small creeks. For example, many Third World countries that are trying to get their country industrialized lack the funds to dispose of their wastes probably. But instead, they dump their toxic pollutants into surrounding bodies of water. All of the toxins that they dump, can be washed out into the rivers, seas, or oceans can contaminate our water we use everyday to wash our face, hands, clean our dishes, and much more.
The advancement of our industrial not only causes us health problem only but it also depleting our ozone and cause us global warming. The technologies that we build some of them which contain CFC Chlorofluorocarbon, a compound consisting of chlorine, fluorine, and carbon, CFC are commonly been used in refrigerators, solvents, cars, and many more. The CFC can break down by strong ultraviolet light in the stratosphere and release chlorine atoms that then deplete the ozone layer. If the ozone layer been depleted the ultraviolet light will go through and can cause us skins cancer.
The advancement of science and technology affected us in many negative ways in term of destruction, pollution, insecurity in daily life, and health problem. Weapons which brought destruction and which help to created war. Harmful affects of chemical such as CFC in our cars, refrigerator, and machinery that destroy the ozone, which protect us from the heat of the sun and also prevent us from have skins cancer. The more machineries and technology we built the more resources we need. The more natural habitat will be destroy so people could get those resources, and the natural habitat is to help us from polluting the air and protect our ozone.
