For much of history, science was a little on the daily life of the people. Scientific evidence itself collected, had some practical applications. However at the beginning of the industrial revolution in the 18th century, that quickly changed. Today, science has a profound impact on the way the we largely technology - the use of scientific knowledge for practical purposes of life.
Certain forms of technology can be well established, it is easy to forget the scientific achievements, it. Refrigerator, must for example its existence to the discovery to take liquids in energy when they evaporate, the phenomenon of latent heat. The first was the principle of evaporative cooling in 1876 in a practical way to exploit, and fridge played a key role in maintaining public health since (see cooling). The first car from the years 1880, with several breakthroughs in physics and technology, including the reliable tools of the high voltage generate Sparks, then this computer for the first time in the 1940s the simultaneous advances in electronics and mathematics.
Other fields of science play an important role in the things that we use or consume every day. Research in the field of food technology has created new ways to preserve and flavor compounds, what we eat (see conservation and food processing). Research in industrial chemistry has a variety of plastic and other synthetic materials, thousands of applications at home and in the industry has created. Made simple to complex forms of synthetic materials and can be used an electric motor, auto parts, scientific and industrial equipment, decoration, to make container and many other articles.
Save with these achievements and the science on technology helps life. Kidney disease, which showed that, once fatal, artificial valves allow again active life suffering the CHD survive machine, which helps many people. Research on the biochemistry of antibiotics and vaccines, the US against infectious diseases and a variety of other drugs used protection to combat health problems. Live the most people on this planet therefore lives longer and healthier than ever before.
The scientific discoveries can have also a negative impact on human affairs. Live easier or more fun adverse and long-term effects are in the last 100 years showed some of the technological advances which make often unpredictable. Industrial chemicals and agricultural use, global pollution, even at remote locations, such as Antarctica, city air by toxic gases from exhaust gas vehicle contaminated are (see pollution). The pace of innovation means that products quickly, in addition obsolescence to a wave of waste (see the solid waste disposal). More important still, the burning of fossil fuels such as coal, oil and natural gas releases carbon dioxide atmospheric CO2 and other substances known as greenhouse gases. The composition of the atmosphere, global warming and the possibility of a major climate change changed these gases in the coming years.
The flag was also used to develop a technology that raises the moral system. This applies in particular in the fields of biology and medicine (see medical ethics). Research on genetic engineering, cloning, in vitro fertilization and gives scientists an unprecedented for a new life, or to new forms which makes designing living organisms. On the other hand, also science can generate technology that will deliberately harm or kill. The fruits of this research are chemical, biological and nuclear weapons, the most destructive of the world has ever known weapons.
