The invention of gunpowder is thought to have originated in the 5th or 6th century in central Asia, but there isn’t any proof that gunpowder was used for warfare until the 12th century, when a kind of rocket was made. The Chinese actually used gunpowder to make firecrackers, which they used on religious festival days.
In the 19th century, Alfred Nobel, the Swedish inventor, made his famous discovery that would change the way that wars were fought. Dynamite was first used in the war in South Africa, and he eventually became a multi-millionaire. Alfred was a pessimist who never experienced real happiness since he felt that he had some responsibility for the loss of so many lives. As a result of these guilty feelings, he established a fund of nine million dollars for the formation of the internationally famous Nobel Prizes, the most important of which is the Peace Prize.

Glass has been made into practical or decorative objects since ancient times. Glass blowing was probably developed in the first century BC in Syria. With this technique the possibilities for shaping glass into different forms became endless.
The Roman Empire used glass more than any other ancient civilisation. Romans adopted the technique from the Syrians and glass soon became fashionable. There were people, however, who regarded it as inferior to materials such as gold and silver. Gallenius, a Roman emperor, used to drink from a glass vessel because he believed that there was nothing less common than glass.

Can you imagine what the world would be like if there were no electricity? In fact, most of what we take for granted would not exist. There would be no computers, TV, cinemas or stereos for our entertainment, and we would not be able to cook and eat in the same way without cookers and fridges. If Thomas Edison had not invented the electric light bulb, we would now still be using candles to see at night. The problem with this energy source is that it uses fossil fuels – we burn coal and oil to generate electricity. Our everyday lives use a huge amount of power, and industry even more. The damage to the environment will increase if we continue to burn coal for energy, which can cause serious air pollution and increase the size of the hole in the ozone layer. Because of this danger, people are now using other sources of fuel, such as solar, wind, and water power.

Lead is now a very expensive metal. At one time it was used extensively for roofing and for water piping because of its softness and resistance to corrosion. But later copper and iron have taken its place. Lead is a gray malleable metal which melts at 327 ̊C, which is low for a metal. Lead is still used for roofing and for making waste pipes and sink traps because it is easily bent into shape; storage battery (accumulator) plates; storage tanks for sulphuric acid; lead shot; solder; screens to stop harmful radiation from radioactive substances. Lead monoxide is used for making glass that is brilliant and sparkling, i.e. decorative tableware.
