Science (arising from the Latin “scientia”, meaning knowledge) is the human effort to understand how the natural world works. Through a broad range of scientific disciplines, mankind uses both observational and experimental methods to observe natural phenomena, prove or disprove theories on those phenomena and expand proven scientific knowledge for advancements in many fields like medicine and engineering.
With the threat of disease and famine, scientists are always discovering new technologies that help humanity and the world. Due to diseases such as cancer and AIDS, money is constantly poured into studies that are devoted to developing cures and treatments. Not only that, but alternative energy is a fast growing market and as carbon-based fuel becomes more scarce, the world turns to scientists to discover alternative energy sources.
