Radar applications
1. The information provided by radar includes the bearing and range (and therefore position) of the object from the radar scanner. It is thus used in many different fields where the need for such positioning is crucial. The first use of radar was for military purposes: to locate air, ground and sea targets. This evolved in the civilian field into applications for aircraft, ships, and roads.
2. In aviation, aircraft are equipped with radar devices that warn of obstacles in or approaching their path and give accurate altitude readings. The first commercial device fitted to aircraft was a 1938 Bell Lab unit on some United Air Lines aircraft. Such aircraft can land in fog at airports equipped with radar-assisted ground-controlled approach systems in which the plane's flight is observed on radar screens while operators radio landing directions to the pilot.
3. Marine radars are used to measure the bearing and distance of ships to prevent collision with other ships, to navigate, and to fix their position at sea when within range of shore or other fixed references such as islands, buoys, and lightships. In port or in harbour, vessel traffic service radar systems are used to monitor and regulate ship movements in busy waters. Police forces use radar guns to monitor vehicle speeds on the roads.
4. Meteorologists use radar to monitor precipitation. It has become the primary tool for short-term weather forecasting and watching for severe weather such as thunderstorms, tornadoes, winter storms, precipitation types, etc. Geologists use specialized ground-penetrating radars to map the composition of Earth's crust.

Once Walt Irvine and his wife Madge, who lived in a small cottage in the mountains, found a dog. He was thin and weak, but he did not let them touch him. He ate the food they gave him only after they had gone away. But when he was strong again, he disappeared.
A few months later, when Irvine was in a train between California and Oregon, he looked out of the window and saw his dog running along the road, two hundred and thirty miles away from home. He got off the train at the nearest station, bought a piece of meat, caught the dog and took him home again. So Wolf, as they called him, came a second time to the mountain cottage. There he was tied up for a week.
To win him became a problem, but Irvine liked problems. At the end of the week he tied a piece of thin bright metal round the dog’s neck with the words: RETURN TO WALT IRVINE, GLEN ELLEN CALIFORNIA. Then the dog was allowed to go, and he disappeared. A day later came a telegram. The dog was reported to have run over hundred miles to the north. Wolf was still going when caught.
This time he was sent back by express train. He was tied up for three days, and was allowed to go on the fourth. And he disappeared again. As soon as he was given freedom he always ran north. He was always brought back weak and always ran away fresh and strong.
At last the dog decided to stay at the cottage, but Irvine and his wife had to wait a long time before they could touch him. When at last he let them do it, they said it was a great victory. The man and woman loved the dog very much.
