Nowadays solar energy is widely used as an alternative form of power. Solar panels transform the energy from the sun into electricity. The first plane that does not need fuel was constructed in France, in 2015. It uses only the sun's energy. The panels are placed on the huge wings of the plane. It doesn’t fly very fast. Solar energy can make the plane move at only 140 miles an hour. However, the plane is able to travel round the world. It is safe and can successfully cross areas of bad weather. In the future, engineers hope to construct a model that people can fly in. Our dream of environmentally friendly transport may come true very soon. Would you like to take a flight on the solar plane?

We are always told that we should clean our teeth regularly to keep them healthy and to have fresh breath. It is believed that people started using a kind of paste to clean their teeth around 5000 years ago. However, the ingredients of these tooth powders were very different from ours. For example, the people of ancient Egypt used salt, mint, dried flowers and pepper to create tooth powder. Later, in the 18th century, in some countries in Europe, people brushed their teeth with burnt bread. The first toothpaste appeared in 1890, in Great Britain. At first it was sold in jars. Then special tubes were designed to make the toothpaste more comfortable to use.

Do you know why it is hot in the summer and cold in the winter? Most people believe that it is because the Earth is closer to the Sun in the summer and farther from it in the winter. But it is not like this at all! In fact, the distance between the Earth and the Sun is largest in July and smallest in January! Scientists suggest that the reason for different summer and winter temperatures is the angle of the Sun’s rays. In the summer, the rays reach the Earth almost at a right angle. Due to this, the rays are not spread out and a smaller area of the planet's surface gets the energy. In the winter, the angle changes and the Sun’s rays are spread out over a larger area. Besides this, the long nights and short days do not give enough time for the land to warm up.

A robot is a machine that does work for people. The word ‘robot’ appeared in the 1920s and it was first used in a science fiction story. In real life, the robot was invented later, in 1954. There are different kinds of robots which are used in different industries. Most of them are operated with the help of a computer program. Instead of humans, robots do hard and boring work in unpleasant or dangerous environments. They usually work faster and more accurately than people. They never get tired and do not make mistakes. Nowadays robots are often used for domestic needs – to clean houses or to look after sick and elderly people. Scientists say that soon robots will become a normal part of our life, like mobiles and computers today.

Nowadays people can’t imagine their kitchen without a refrigerator. The first refrigerators appeared at the end of the 18th century. They looked different: they were just iceboxes. The refrigerators of the past were just wooden boxes, sometimes lined inside with metal. People put ice into the box and then placed the food inside to keep it cool. The refrigerator, similar to the one that we have now, was produced by General Electric in 1911, in France. It was very expensive. In those days, with the same money you could buy two cars. Today, in developed countries almost every family has enough money to buy a refrigerator for their kitchen. It’s hard to imagine how difficult and uncomfortable our lives would be without a refrigerator.

Without the energy from the Sun, the Earth would have no life at all. Nowadays everyone knows that the Sun is a star. Like all stars, the Sun is a great burning ball of gases. To us, it seems large and red. The other stars look white or light blue because they are much farther from us than the Sun. In the past, many people believed that the Earth was the centre of the universe. They thought that the Sun and the stars went round it. Only in 1543, a great Polish scientist published a book in which he tried to prove a different point of view. According to him, the Earth and the other planets moved round the Sun. Those people who supported the scientist were often imprisoned and even killed.

The carrot is a root vegetable which consists mostly of water and sugar. The carrots that we eat today originated from the wild ones which grew in Europe and Asia. The vegetable tasted sweet and the people began to use it as food.
There are two main types of carrots. There are eastern carrots that have dark purple roots and western carrots with orange roots. In fact, orange carrots first appeared in Europe in 1721. Dutch farmers selected orange carrots because orange is the colour of the Dutch Royal Family. Now orange carrots are widely grown all over the world. In modern households carrots are cooked and eaten in different ways. The vegetable is boiled, fried, baked and eaten raw. People also make juice from it.

Since 2007 high-speed trains have become a common type of transport in Europe. They make it possible to cut travel times by hours. The trains travel at 350 kilometres an hour, and this is not the limit! The only problem for the engineers is the loud noise the trains produce. People living in the areas the trains travel through suffer from the noise greatly. For the passengers, the situation is different. For their comfort, all the carriages are made sound-proof from the inside. Travelling on high-speed trains is comfortable and pleasant. In the future, a high-speed railroad network could cover most of Europe. For example, a trip from Paris to Rome could take only 3 hours!

Venus is one of the hottest planets in the Solar system. The temperature on its surface is 482 degrees. This unfriendly place looks much the same as the Earth 4 billion years ago. Both planets were formed from the same gas cloud but Venus lost most of its water and atmosphere. This happened because the planet turns very slowly. As a result, now it has no magnetic field to protect it from the Sun's winds. The planet has turned into a lifeless desert. Most space modules that were sent to Venus, could not work on the planet more than two hours. The acidic clouds and high pressure quickly made them absolutely useless.

Studies of the atmosphere first received technical support in 1912. Equipment to measure temperature and pressure was invented in Germany. But the question was how to raise it high into the air. In 1921, Russian engineers suggested using planes. The special equipment was put on planes that made regular flights. Thanks to this, scientists got a lot of new information about the structure of the atmosphere. Nowadays scientists use modern flying laboratories to study the structure of clouds at different levels. Unlike the first planes, these laboratories can work in any weather and are able to predict climate changes.

Wombats are exotic animals that only live in Australia. They have become an unofficial symbol of the country. In 1974 a wombat appeared on an Australian stamp for the first time. Since then it has been regularly used on different Australian stamps and coins. Wombats look like little bears and prefer grass to meat. They also love eating berries, plant roots and mushrooms. Like camels, wombats drink little water because there is enough water in fresh grass. Wombats spend most of their life in holes under the ground. With their strong arms and long nails they are able to dig very long and complex tunnels. Fortunately, wombats have few enemies in the animal world. Most wombats live around 15 years.

The word ‘tsunami’ can be translated from Japanese as ‘big wave’. It describes a natural process that can be dangerous for people and their homes. Most of the huge waves appear after earthquakes. Most waves are born in the Indian and the Pacific Oceans where volcanoes are active. The mass of water rises from the bottom of the ocean and moves to the shore. It moves at the speed of a plane and can be up to 40 meters high. The wave is very powerful and dangerous. In 2004, a tsunami happened in the Indian Ocean. It was one of most terrible natural disasters in history. It hit 14 countries bordering the Indian Ocean. Thousands of people were killed or went missing.

Snowdon is the highest mountain in Wales. It is located in a national park. It stands at 1085 metres above sea level, and it is often described as the busiest mountain in Great Britain. Snowdon is very popular with tourists. If you are strong and brave enough to get to the top, you can enjoy wonderful views from there. On a clear day, you can see as far as Ireland! During the summer months there is a café at the top. There, tourists can get a welcome cup of tea, or soup if the weather is cold. If you feel too tired to walk back, you can always take the train down the mountain. The mountain railway was built in 1896. It is safe, and there have never been any accidents on this route.

Most people enjoy watching the night sky. And the brightest object in the sky is the Moon. Every night the Moon rises in the East and sets in the West. It takes about 27 days to go around the Earth, and it’s an interesting fact that we always see the same side of the Moon. The Moon is the closest object to the Earth. It would take us only 13 hours to get to the Moon by rocket. If we were able to travel at the speed of light, it would take a bit less than two seconds.
There is a very thin atmosphere on the Moon. Life is not possible there. In spite of this, the Moon can be used as a base for space exploration and even for space tourism. Some space companies say that they will be able to take tourists to the Moon as soon as in 2020.

People have always wanted to discover new things and new worlds. We have built spaceships to go to other planets and are planning to visit other galaxies one day. Meanwhile, we know very little about our own planet. The oceans, which cover 70 percent of the planet, are an unknown world to us. The Pacific Ocean is the largest one. The lowest point on the Earth is also there. It is called Challenger Deep and it was discovered in 1875. The Pacific Ocean stretches from the Arctic Ocean to the coast of Antarctica, but most of its water is in the warm tropics, which makes it warm. A lot of fish and animals live in the Pacific Ocean. The place is still waiting for researchers to discover its secrets for us.

The Arctic Ocean is the smallest ocean of the world. It covers the northern polar region of the Earth. The Arctic region is a very cold place. The lowest recorded temperature there is minus 68 degrees. In spite of the cold, a lot of animals live on the Arctic ice. The polar bear is one of them. Now, due to global warming, the polar bear is in a serious trouble. The thing is that polar bears hunt seals and they need ice to do this. The bears wait for seals on the ice, hunt them in the water and go back to the shore. If the ice is too thin, it breaks under the bears’ heavy bodies and they may drown. The situation is getting worse and some researchers say the ocean may become ice-free as soon as 2050.

In 1642 a French student invented the first mechanical calculator. He was only 18 and the counting machine was a present for his father. The father worked as a tax collector and the young man wanted to make his job easier.
The talented inventor made several machines but nobody was interested. The young man was ahead of his time. Many years passed before people realized how useful these machines could be and started mass producing them.
Today most mechanical calculators have been replaced with electronic models. These small devices can perform a lot of mathematical operations. You just need to enter the numbers by pressing the keys and you’ll see the final result on the screen in no time.

One day a young man who lived near the lake in a small American town asked himself, “Why can’t people ski on water if they can ski on snow?” With his brother’s help he constructed several models of skis to test his ideas. He experimented on the local lake for a few days and created skis suitable for the water. This happened in 1922. The young man, who was only 18 at that time, didn’t patent his invention. However, he performed a lot of shows across the country that made him and the sport of water skiing popular. Later, he was recognized as the creator of a new sport – water skiing.
Water skiing equipment has been greatly improved since that time, and the number of people who enjoy this sport is growing in many countries.

The ninth planet of the solar system was discovered not long ago. It happened in 1930. Scientists had been hunting for the planet for a long time. They had calculated its probable position but there was no proof that the planet really existed. It was too far away for the telescopes of that time to find it. It’s worth mentioning that the first photos of the planet were taken by a very young researcher. He was only twenty-four and had no formal education in astronomy. However he was deeply involved in the search for the ninth planet. The planet at the edge of the solar system was called Pluto, after the Roman god. The name for the planet was suggested by an 11-year-old British girl.
