A communication system that does not allow an interchange between the message source and the receiver is said to be a one-way or "simplex" communication setup. One that does allow an interchange is a two-way or "duplex" setup. Noise is an important concept in communication theory. Noise is defined in communication theory as any signal that interferes with the message being sent and is an undesired disturbance in a communication system. Radio static is a form of noise. Dirt on a camera lens is noise also.

To determine blood groups, there is a method of extracting a chemical from human blood which, when mixed with a sample of the blood in question will react in a particular way according to the blood group. However, to get enough of the solution a great deal of human blood is required. But fortunately, snails’ eggs, which are the size of a pinhead, contain the same chemical – in fact, the blood of five donors would be required to supply the same amount of the chemical as is found one of the snail’s eggs.

Before machines were invented, shoes like the ones we wear today took a long time to make. In 1846, Elias Howe made a strong sewing machine, and then, in 1858, Lyman Blake changed this machine so it could sew shoes. In 1875, Goodyear Welt made a new machine for making shoes quickly. It was called the Goodyear Welt sewing machine. With this machine Goodyear made cheap shoes from rubber. Nowadays we remember Goodyear because he has made other things with rubber.
Today, people wear shoes made from animal skins, cloth, rubber, and plastic. Shoes have come a long way from the first skin and leaf shoes – and with new machines, they will change a lot more.

Probably since the time of the first humans, people have eaten honey made by bees. For many thousands of years, they took the honey from bees’ nests in trees without understanding very much about the lives of bees. Slowly, however, people realized that it would be simpler to keep bees than to have to try to find their nests. At first they kept them in hollow parts of trees or small clay containers which they hung from the trees. Nowadays in most countries they are kept in wooden hives.
