Traffic lights were invented in the United States and introduced in New York in 1918. Traffic lights are used to control the flow of traffic, determine the right of way at intersections and give greater safety to drivers. Traffic lights came to be used for the first time in Britain in 1928.

What is a Catalytic Converter?

-
Image
A catalytic converter is used to reduce the amount of harmful gases pumped into the atmosphere by vehicles. The converter is a metal case containing a metal or ceramic in the shape of a honey comb which is coated with a precious metal like platinum or rhodium which acts as a catalyst. The converter is fixed into the exhaust pipe of the vehicle. As the engine's exhaust gases flow through the honey comb, the catalyst converts the harmful gases like carbon monoxide, oxides of nitrogen and hydrogen into water vapour and carbon dioxide.

How do We Taste and Smell Things?

O ur nose and mouth have special receptor cells, which when stimulated by chemical molecules, send nerve impulses to the brain. Our tongue is covered with tiny growths or papillae. Some papillae contain small group of cells known as taste buds. Each taste bud contains four to twenty receptor cells with short sensory hair. These hair react to molecules dissolved in the saliva. We can taste four main kinds of tastes. Bitterness is tasted at the back of the tongue, sourness at the sides , sweetness at the front and saltiness can be tasted all over. Our nose has cell receptors at the roof of the nasal cavity. These receptors have sensory hair that branch and project into the mucus that lines the cavity. Molecules in the air dissolve in the mucus and stimulate these hair. There are about 15 kinds of smell receptors which can detect over 10,000 different smells .

How is Air-traffic Control Organized?

-
Image
A ir-traffic controllers make sure that planes take off and land safely and fly without any delays. The pilots are told where to fly so that no air collision takes place. The radar provides the air-traffic control staff with updated information about the exact position, destination and identity of every plane and about the weather conditions. When a plane is about 2,700 metres away from an airport and 600 metres above it, it enters the terminal control area. Working from this centre, the controller guides the pilot telling him at which height to fly or wait and circle the airport, when the plane has to land, etc. The controllers are also responsible for aircraft taking off and they also control planes throughout their flight from one airport to the next.
