Science is the organized systematic pursuit of knowledge. The purposes of science are to explain and manipulate the physical world. A common concern is uncertainty over where science will lead us next. Because of its potency, like the analogy of a child with a gun, science must be balanced with social responsibility. Despite the fears about science, the overall goal of science is to produce a better world.
Scientists feel that by improving our knowledge of nature they can benefit mankind.
Based upon the two abovementioned simple goals science would seem to be a relatively benign pastime, but the implications of science can be very potent. Defining the structure of an atom has given us the power to split the atom, producing helpful medical tools and destructive nuclear weapons. A better understanding of gravity has allowed us to put satellites into space allowing better global communication and navigation as well as clandestine spying operations. Because of the value of many scientific discoveries, it is no surprise that some of the most advanced research is funded by armies around the world. Probably the most important scientific invention ever was agriculture.
