A powerful example is the value of electricity. Electric light benefits people every day in inventions like lamps, traffic lights, appliances and computers. Instead of reading by candlelight at night, a click of a switch turns on a light. Homes can be heated and air-conditioned.

A fan plugged into an outlet can blow a nice breeze or a ceiling fan can cool off a room with thanks to scientific electricity. Refrigerators keep food fresh and freezers store food longer.

A dishwasher washes, rinses and dries dishes. Traffic lights prevent traffic accidents at intersections. Clothes can be washed in a washing machine and dried in an electric dryer. Toast bread in a toaster, use a microwave or stove to cook and bake a cake in an oven. None of this would be possible without electricity.

Science Speeds Up Transportation Science has helped speed up the pace of contemporary life.

A trip that took weeks or longer on foot or horseback was shortened by the invention of trains. Boats and automobiles soon followed and later the airplane became the quickest way for people to travel.

Rockets and space shuttles can now fly into outer space. Weather and Weather-related Disasters Through meteorological science and technological advancements, weather forecasts are predicted with varying degrees of accuracy.

Predictions help keep people safe in areas where major storms are going to hit. These predictions give enough warning now for people to be able to evacuate for the storms arrive.

This includes hurricanes, tornadoes and earthquakes. In less extreme ways, weather forecasts help people plan for travels or daily treks. This might include hailstorms, thunderstorms, floods, snow or excessive heat or cold. Science in Medicine Science makes life safer in medicine. Antibiotics heal bacterial infections.

Vaccinations protect people from diseases that were once considered fatal, such as tuberculosis and polio.

Current vaccinations prevent shingles and influenza. Blood tests can determine cholesterol and sugar levels as well as vitamin deficiencies. Medical equipment offer views of the inside of human and animal bodies to detect abnormalities.

This is done through the use of X-rays, magnetic resonance imaging and computed tomography, among others. Medicine is one of the quickest changing and evolving forms of science.

Plants and Food Science is responsible for plants that grow in greenhouses. It keeps farmers working more efficiently and irrigation systems watering large fields of crops.

A sprinkler waters a small yard to keep the grass green. Foods can be bought out of season due to botanical advancements and transportation options. Hybrids and more varieties of foods are offered.

Vitamins, minerals and caloric values in foods can be calculated to maintain health benefits.

Definition drug. From its emergence as an independent nation, the United States has encouraged science and invention. It has done this by promoting a free flow of ideas, by encouraging the growth of "useful knowledge," and by welcoming creative people from all over the world.

A state is a compulsory political organization with a centralized government that maintains a monopoly on the legitimate use of force within a certain geographical territory.. Many human societies have been governed by states for millennia, however for most of pre-history people lived in stateless first states arose about 5, years ago in conjunction with rapid growth of cities.
