Physics, for example, teaches us how mirrors work, how glasses can aid one's vision and how heat is treated by various household materials (plates and utensils). Chemistry discusses the principles of matter, like atoms, molecules and compounds. It discusses the countless different substances that can arise from the smallest variations within compounds. These atoms, molecules and compounds make up the water we drink, the food we eat, the air we breathe, the medicines we take when we are sick. Some we can't possibly live without.
Biology, the study of life, teaches us why we are the way we are, why we need what we need to survive, how all living things are categorized, when we all came from. These, and countless other questions and answers are all related to science.
There have been many tremendous advances in technology over the last decade, so many in fact, the pace is accelerating. Everyday new things are discovered with our ever-increasing scientific knowledge. Cancer research has found a virus capable of killing cancerous tumours in rats. Although this has not been sufficiently tested for use on people yet, scientists predict that testing on human volunteers may come into effect in around two years. There has also been the ever-controversial breakthroughs in the cloning of sheep and mice, which can have a great impact (whether good or bad) on the future.
Technology has also brought us closer together. The introduction of the mobile/cell phone has made communicating with each other more instantaneous, as has the development of computer technology with programs such as Skype.
We have all become accustomed to the advantages that science has brought us. Today's modern world would be unimaginable without the continuing progress of science.
