Communications

Engineering allows us to connect and communicate with our friends and family in ways that were just fantasy 20 years ago.

No so long ago, letters took several days to reach their destination and getting message to someone who lived a continent away could take a month or more – or cost a small fortune. Now, thanks to our smart phones, voice-over-internet, and social networks on our computers, communicating with people in Australia can be as easy as talking to your next-door neighbor.

All of the technologies that have connected us to people around the world where made possible by engineers. Engineering has even revolutionized the way packages are sent through computerized tracking systems and superior transportation methods.

The engineers of today and tomorrow shape the way we work, play, and conduct business by continuing to develop and refine the ways that we communicate.

    Karl G. Jansky Very Large Array (VLA)
    A series of radio antennas can produce an image equal to that of a telescope 22 miles across.
    Radio telescopes receive radio waves emitted by celestial bodies -- stars and other objects in space -- and convert those signals into images using computers and video displays. Radio signals from far away are very weak and require very large receivers to detect. Since a single receiver big enough to collect signals from many light-years away would collapse under its own weight, engineers at the National Radio Astronomy Observatory created the Very Large Array (VLA). Twenty-seven, 82-foot-diameter dishes combine their signals to produce an image equal to one made by a telescope 22 miles across. The Array's dishes are linked by cable, which makes it the world's largest of this type.
