Look around. I wonder what things are part and parcel of your life? What is it that you can't do without in the 21st century? I bet you'll make a long list of things which were once somebody's great inventions but by now, have become your bare necessities.
Buzz-buzz. The telephone is ringing. Pick up the receiver, please. You are on the phone now. You can talk to a relative or friend who is far away. It was Alexander Bell who made it possible for you by inventing an apparatus for sending or receiving sound in 1876. The telephone was big and immobile for a long time, but today there are cell-phones, that is small gadgets which you can carry and use anywhere. But don't take it for a children's game "Telephone " which is popular in many countries.
Have you got a travel bug? Do you feel like taking a trip? Don'tleave your digital camera behind. It will help you to catch the best moments of your journey to remember it by. Scientists invented the good old camera sensitive to light to make photos ofpeople and places.
What is your favourite FM-radio station? Please tell me what helps you to enjoy listening to music the best - the radio, your walkman or your IPOD. They all came from an apparatus for receiving sounds broadcast through the air. Thanks to them, we have a chance to get entertained wherever we go.
You won't believe it, but some of the inventions were made by accident! Penicillin, for instance, the first type of antibiotic. It was Alexander Fleming, a Scottish scientist who was doing experiments with bacteria. One day one of the dishes where he was growing bacteria, got soft and green. He was about to throw it out when he noticed that the soft and green material had killed the bacteria. This discovery made him a Nobel Prize winner in 1945. I'm dead sure Fleming's invention will live far into the 21st century...
