Role of Transisters
Transisters have helped us to develop logic circuits that can perform certain logic operations (i.e. they can virtually think !)

Important Establishments
There are stars in the universe that cannot be seen through our eyes. The reason is that these stars do not radiate EM waves in the visible region, instead they radiate Radiowaves. But, today we can detect these stars by using Radio technology. Huge Observatories are set up with dish antennae that can detect radio waves from these stars. One such observatory is in New Mexico, called as VLA (Very Large Array) , it has 27 huge dish antennae and it's range can move through miles into the space.

 * 2) International Space Station
 * 3) Observation of Stars through Radio technology
