Calculate a baseball player's batting average. Calculating a baseball player's batting average is not a difficult task at all. A batting average represents the percentage of at bats that result in hits for a particular baseball player. The formula is: That's all there is to it.
To fly under the radar means to act in a way so as to actively avoid detection. It is the opposite of 'in your face'. There is an element of getting away with something but it is not necessarily bad.
It is a system based on electromagnetic waves that are used to identify altitude, direction, and range of moving and stationary objects. It can also be used to identify the speed of moving objects like aircraft, ships, and motor vehicles. Sir Robert Watson-Watt is credited with creating the first practical RADAR system.In early 1935, he proposed a system that could detect and locate aircraft with the use of radio technology. On February 26, 1935, he successfully demonstrated the reflection of radio waves by aircraft.oltan Bay, a Hungarian physicist, created a working model of radar in 1936. The British were the first to use the radar system for defense purposes. Radar technology is widely used for air traffic control and navigation.
