Electricity
In 1752, Ben Franklin proved that static electricity and lightning were one of the same. This experiment is known as key tied to a kite string during a thunderstorm. In 1800, Alessandro Volta invented the first electric battery. His name was used in creation of the notion of voltage (volt).
The Automobile
The automobile was first invented and perfected in Germany and France in the late 1800s, though Americans quickly came to dominate the automotive industry in the first half of the twentieth century. Henry Ford innovated mass-production techniques that became standard, and Ford, General Motors and Chrysler emerged as the “Big Three” auto companies by the 1920s.
The Airplane
On December 17, 1903, Wilbur and Orville Wright made four brief flights at Kitty Hawk with their first powered aircraft. The Wright brothers had invented the first successful airplane. The Wrights used this stopwatch to time the Kitty Hawk flights.

Water
In ancient Rome, the Cloaca Maxima, considered a marvel of engineering[.
Public latrines were built and the Roman Empire had indoor plumbing, meaning a system of aqueducts and pipes that terminated in homes and at public wells and fountains for people to use.
Roman towns and garrisons in the United Kingdom between 46 BC and 400 AD had complex sewer networks sometimes constructed out of hollowed-out elm logs, which were shaped so that they butted together with the down-stream pipe providing a socket for the upstream pipe.
Apple
Apple Computers, Inc. was founded on April 1, 1976, by college dropouts Steve Jobs and Steve Wozniak, who brought to the new company a vision of changing the way people viewed computers. Jobs and Wozniak wanted to make computers small enough for people to have them in their homes or offices. Jobs and Wozniak started out building the Apple I in Jobs' garage. The Apple II revolutionized the computer industry with the introduction of the first-ever color graphics.1 Sales jumped from $7.8 million in 1978 to $117 million in 1980, the year Apple went public.

Telephone
Alexander Graham Bell was awarded the first U.S. patent for the invention of the telephone in 1876. Elisha Gray, 1876, designed a telephone using a water microphone in Highland Park, Illinois. Tivadar Puskás proposed the telephone switchboard exchange in 1876.
The Internet
The first workable prototype of the Internet came in the late 1960s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Originally funded by the U.S. Department of Defense, ARPANET used packet switching to allow multiple computers to communicate on a single network. The online world then took on a more recognizable form in 1990, when computer scientist Tim Berners-Lee invented the World Wide
Health
Recent advances in imaging technology -- like CT scans, MRIs, PET scans, and other techniques -- have had a huge impact on the diagnosis and treatment of disease.
More detailed imaging is allowing doctors to see things in new ways. Imaging can provide early and more accurate diagnoses. In some cases, it might even lead to better and more successful treatment.
