People who daydream are often thought of in negative terms, such as being lazy or not doing what they should be doing. However, scientists who study the brain have learned many interesting things, especially from studying the brains of daydreamers. In fact, far from being a waste of time, some scientists believe that daydreaming is a healthy and useful activity for all of our brains. In order to study the brain, scientists use special devices that scan the brain and show pictures of which parts of the brain are active at certain times. When a person is daydreaming, the device will show a distinct pattern of activity in the brain called the “default” mode of thinking. In the default mode, the top or outside part of the brain is very active. Actually, several regions of the brain are interacting in this mode. Some scientists describe this mode as a time when the brain focuses on itself rather than focusing on the environment around the person. Typically, this occurs when a person is doing simple, tedious work or performing routine actions that don’t need much attention, like walking to school or cooking simple foods. People tend to daydream during such activities. The importance of daydreaming lies in developing both creative and social skills. When the mind is not engaged in dealing with one’s immediate situation or problem, then it is free to wander. A time of wandering allows the mind to create things. New inventions may be imagined, or possible solutions to a problem can be planned. For example, solutions for problems in relationships with other people may come to mind. In fact, most daydreams involve situations with others. Perhaps these are daydreams based on memories of the past, or daydreams of what might be in the future. In either case, daydreams help us develop the appropriate skills we can use in real interactions with others. As a neurologist, Dr. Marcus Raichle of Washington University explains: “When you don’t use a muscle, that muscle really isn’t doing much. But when your brain is supposedly doing nothing and daydreaming, it’s really doing a tremendous amount.” During the so-called “resting state” the brain isn’t resting at all!

It is hard to think of a world without gas or electricity. Both are commonly used for lighting and heating today. We now can instantly flick a lighter or strike a match to make a flame. But it was not long ago that there were no such things as matches or lighters. To make
fire, it was necessary to strike a piece of iron on flint for sparks to ignite some tinder. If the tinder was damp, or the flint old, you had to borrow some fire from a neighbor.
We do not know exactly when or how people first used fire. Perhaps, many ages ago, they found that sticks would burn if they were dropped into some hole where melted lava from a volcano lay boiling. They brought the lighted sticks back to make their fire in a cave. Or, they may have seen trees catch fire through being struck by lightning, and used the trees to start their own fires.
Gradually people learned they could start a fire without traveling far to find flames. They rubbed two pieces of wood together. This method was used for thousands of years.
When people became used to making fires with which to cook food and stay warm at night, they found that certain resins or gums from trees burnt longer and brighter. They melted resins and dipped branches in the liquid to make torches that lit their homes at night. Iron stands in which torches used to be fixed can still be seen in old buildings of Europe.
There was no lighting in city streets until gas lamps, and then electric lamps were installed.
Boys ran about London at night carrying torches of burning material. They were called torch boys, or link boys, and earned a living by guiding visitors to friends’ houses at night.
For centuries homes were lit by candles until oil was found. Even then, oil lamps were no more effective than a cluster of candles. We read about the splendors and marvels of ancient palaces and castles, but we forget that they must have been gloomy and murky places at night.

What form of street lighting was used in London when link boys used to work there?

Think for a moment about the last music album you bought. Most likely, you’ll think of the singer or band that made you want to buy the album. You might even know the name of the guitar player or the drummer. Those talented performers, however, are only some of the people in the music industry work behind the scenes, but the roles they play in the musical progress are very important. Songwriters: Songs begin with the songwriter. Some songwriters work alone, but many work in teams that combine the talents of a lyricist, who writes the words to songs, and an instrumentalist, often a piano player or guitarist, who writes the music. Many of today’s pop stars work with songwriters. For example, some of Lady Gaga’s biggest hits were written by Nadir Khayat, also known “RedOne”. Some songwriting teams have become very famous, such as Mike Stock, Matt Aitken, and Pete Waterman, who were responsible for many big 1980s pop hits.
Arrangers: After a song has been written, music arrangers make it more appealing by deciding which instruments will be used, what tempo, or speed, the song will have, and whether the song should have a lower or higher pitch. A good arrangement can bring a song to life and make it a classic.
Studio Musicians: Not every singer or instrumentalist can be a star, and many work in the background as studio musicians. These artists are not a part of any one musical group. Instead, they are hired for recording sessions that eventually become the albums you buy, as well as soundtracks for television shows, movies, and radio ads.
Recording Engineers: Recording engineers also play a major role in creating the final sound that you hear. First, these engineers set up the recording studio, the room where the performers play, placing musicians and microphones in exactly the right places to get the best sound. Next, they use electronic equipment, such multi-track recorders, to capture the music. Finally, long after the musicians have gone home, recording engineers use a mixing board to balance the melodies and rhythms of each musician, and sometimes to incorporate special sound effects or additional tracks. Many people make a living with music. You may not recognize all of their names, but all of them work together to create the songs you love to listen to.

Carbon dating can be used to estimate the age of any organic natural material; it has been used successfully in archeology to determine the age of ancient artifacts or fossils as well as in a variety of other fields. The principle underlying the use of carbon dating is that carbon is a part of all living things on Earth. Since a radioactive substance such as carbon-14 has a known half-life, the amount of carbon-14 remaining in an object can be used to date that object.
Carbon-14 has a half-life of 5,570 years, which means that after that number of years, half of the carbon- 14 atoms have decayed into nitrogen-14. It is the ratio of carbon-14 in that substance that indicates the age of the substance. If, for example, in a particular sample the amount of carbon- 14 is roughly equivalent to the amount of nitrogen-14, this indicates that around half of the carbon- 14 has decayed into nitrogen-14, and the sample is approximately 5,570 years old.
Carbon dating cannot be used effectively in dating objects that are older than 80,000 years. When objects are that old, much of the carbon-14 has already decayed into nitrogen-14, and the molecule amount that is left doesn’t provide a reliable measurement of age. In the case of older objects, other age-dating methods are available, methods which use radioactive atoms with longer half-lives than carbon has.

FIRST TIME IN THE AIR
When John Mills was going to fly in an aeroplane for the first time, he was frightened. He did not like the idea of being thousands of feet up in the air. “ „I also didn‟t like the fact that I wouldn‟t be in control,” says John. 
“I‟m a terrible passenger in the car. When somebody else is driving, I tell them what to so. It drives everybody crazy.”
However John couldn‟t avoid flying any longer. It was the only way he could visit his grandchildren in Canada. 
“I had made up my mind that I was going to do it, I couldn‟t let my son, his wife and their three children travel all the way here to visit me. It would be so expensive for them and I know Tom‟s business isn‟t doing so well at the moment – it would also be tiring for the children – it‟s a nine-hour flight!” he says. 
To get ready for the flight John did lots of reading about aeroplanes. When he booked his seat, he was told that he would be flying on a Boeing 747, which is better known as a jumbo jet. “I needed to know as much as possible before getting in that plane. I suppose it was a way of making myself feel better. The Boeing 747 is the largest passenger aircraft in the world at the moment. The first one flew on February 9th 1969 in the USA. It can carry up to 524 passengers and 3.400 pieces of luggage. The fuel for aeroplanes is kept in the wings and the 
747‟s wings are so big that they can carry enough fuel for an average car to be able to travel 16,000 kilometres a year for 70 years. Isn‟t that unbelievable? Even though I had discovered all this very interesting information about the jumbo, when I saw it for the first time, just before I was going to travel to Canada, I still couldn‟t believe that something so enormous was going to get up in the air and fly. I was even more impressed when I saw how big it was inside with hundreds of people!” 
The biggest surprise of all for John was the flight itself. “The take-off itself was much smoother than I expected although I was still quite scared until we were in the air. In the end, I managed to relax, enjoy the food and watch one of the movies and the view from the window was spectacular. I even managed to sleep for a while! 
Of course,” continues John, “the best reward of all was when I arrived in Canada and saw my son and his family, particularly my beautiful grandchildren. Suddenly, I felt so silly about all the years when I couldn‟t even think of getting on a plane. I had let my fear of living stop me from seeing the people I love most in the world. I can visit my son and family as often as I like now!”

How did John feel when the aeroplane was taking off?
