The Radar

Before its Invention

10,000 BC: To get desirable weather people would pray to gods or do other practices in hopes of rain or other desired weather. It's unpredictable, more times than not nothing happens.

Everything-1935: Storms and other weather is completely random. Damage is caused and farms , towns or cities can be destroyed.

1915: First ever recorded Aerial attack on England. Happened during World War I, there was no warning that it was coming and many people get hurt and much damage is caused.

The Invention of the Radar

1886-1888: Heinrich Hertz, performed experiments with radio waves. It showed that some of them would pass through objects and some would bounce back.

June 17th 1935: Robert Watson-Watt, and his assistant Arnold Wilkins with funding by the defense ministry of the United Kingdom, build the first radar system to detect planes, coming in for aerial raids.

1939-1945: Radar is used by every major country in World War II. Used for the detection of ships, planes,

In Modern Times

1947-1991: Early warning radar systems are created for the cold war. They are used to detect long range targets such as ICBMs, and give a early warning.

1958: Large Radar telescopes are used to examine planets .

8/23-8/31/2005: Hurricane Katrina came through and thanks to Radar people were able to evacuate the area.

Today: Radar is being used for Air traffic control, weather services, and the military.

Impact of the radar

Today the Radar is used daily by Air ports, weather services, boats, and the military. Without it weather would still be entirely unpredictable. Warfare would be different, quite possibly the World Wars could have been lost. Air traveling might not be as effective or safe as it currently is. Naval transportation would have no way of knowing if they were driving right into a storm. Without it the world would be very different.
