Modern technology has advanced at a dizzing pace and in the years sice 1990 the world has witnessed the advento f the airplaine, rocket, space fligh, electronics, nuclear power, antibiotics, insecticides, and the many other inventions. Technology has also led to important politicial changes in the world. In the 1900s, the United States rather than Great Britain became the tecnological leader and as a consequence also became the world´s most powerful nation.
Even more important, each advance openened up new horizons for science and led to further progress in technology. New industries were created as thousands of new products became available. Among the products of the new tecnology were the radar, antibiotics, the jet aircraft, atomic weapons, nuclear reactor, space travel, solar energy, computers, lasers, and robots, to name only a few. Today, the pace of change has accelarated and new technologies are being developed so rapidly that their effects are hard to foresee.
