What are the seven wonders of the modern world?
Control of diseases Vaccines and antibiotics have cut the toll in death and misery from many infectious diseases. In the late 1970s, for example, small pox was declared extinct. And genetic engineering may yield more weapons against diseases.
Electric power In little more than 100 years the world has been transformed by the production of energy in a form that can be conveniently used to do all kinds of work.
Space exploration Age-old dreams, including walking on the moon and close-up looks at other worlds, have come true.
Communications and information processing Almost any spot on earth is no farther away than the time it takes for a signal traveling at the speed of light to get there; hand in hand with this communications capability is rapid access to huge amounts of information, made possible by the computer.
Organ transplants and artificial organs Loss of function of a vital organ-whether because of age, accident, or disease-no longer must mean loss of life. Kidney, Liver, heart, and marrow transplants, for example, are prolonging people’s lives; and the transplanting of brain tissue is under study. There is also progress in creating and implanting completely artificial tissues and organs, e.g. mechanical hearts.
Supermaterials and microtechnology New kinds of ceramics and plastics can be tailored to have the exact combination of properties desired for new information, communication, and medical technologies. This is made possible through new techniques of engineering at the microscopic and even molecular levels.
Lasers and other optical technology The use of lights to perform tasks requiring pinpoint accuracy, as well as to carry information, has found a place in the modern world in everything from the optical scanners at supermarket checkout counters, to eye surgery, to weapons systems-almost before people learned that laser stood for light amplification by stimulated emission of radiation.

But some limit the modern wonders to geographical formations, so an alternate list is:
1. Suez Canal
2. Dneproges Dam on the Dnepr River in Russia
3. Atomic Energy Research Establishment at Harwell, England
4. Alaska (or Alcan) Highway, connecting Alaska with Canadian and other United States highways
5. Golden Gate Bridge in San Francisco
6. Eiffel Tower in Paris
7. Empire State Building in New York City
