Internet was first used for military purpose which used the concept of packet networking. ARPANET was the first internet protocol to be used for communication.
The Aegis Combat System is the most important fleet improvement of the last 50 years. It is an integrated system of very powerful radars, computers and missiles that together cast a protective dome over not only the ship it's on, but all the ships close to it. The system has only one major problem: its radars are so powerful they can instantly cook any bird that flies too close to the ship carrying them.
they used to have little mice that would run out on the fields and that would transmit energy to the radars!!! isn't that incredible!!!!!
Yeah, that was Radars first name.
cyclone watch is used. satellites and radars help us too!
True. Doppler radar can detect tornadoes.
Tornadoes activity is monitored largely using a network of Doppler radars. In the U.S. those radars are owned and operated by the National Weather Service, which is an agency of the federal government.
There are 155 Doppler radars across the US and around 122 local offices.
They use science for things like radars, computers etc. so they can see the criminals
Radars are used in various applications such as air traffic control, weather monitoring, maritime navigation, and military defense. They work by emitting radio waves that bounce off objects and return signals, allowing the detection of the object's location, speed, and direction. Advanced radar systems now include features like target identification and tracking, Doppler processing, and integration with other technologies for enhanced situational awareness.

nothing absolutely nothing
Microwaves are typically used for radars because they have the right combination of properties, such as being able to reflect off objects and being able to penetrate various weather conditions. These microwaves have wavelengths ranging from one meter to one millimeter.
