At first, he was very happy with it. “its a nice crown,isnt it?” he asked his men. Later,however, he began to doubt that it was a real golden crown.”Is it made completely of gold?” he wondered. He sent it to Archimedes and asked him to find out the truth. “This problem seems difficult to solve, What should I do?”thought Archimedes. Archimedes was still thinking about this problem as he filled his bath with water. When he got into the bath, some water ran over. “Thats it!”shouted Archimedes. “I know how to solve the kings problem!” Archimedes went straight to the palace to see the king. First, he weighed the crown and asked the king for some gold of the same weight. Next, he put two pots into two big bowls and filled both pots with water. He put the gold into one pot, and some water ran into the bowl. Then he put the crown into the other pot. This time, even more water ran into the bowl. “Look at this,”said Archimedes to King Hiero.” A crown made completely of gold displaces less water than a crown made of gold and another metal. This crown displaced more water than gold of the same weight,so Im certain that its not completely made of gold.” “The crown maker tricked me, didnt he? What a bad man he is!”shouted King Hiero. He then sent the crown maker to prison.Unit 2 Great mindsIn this unit, you will learn about great minds such as Albert Einstein.Reading Two geniusesMany people consider Albert Einstein(18791955)a genius. This story about him shows that he also Had a sense of humour. Einstein often received invitations to explain his theories at different universities. On these trip, his driver Hans often said to him, “Its a pleasure to drive a genius like you, Dr Einstein.”One evening ,on their way to a university, Einstein said, “Im so tired. I wish I could avoid giving my lecture tonight, Hans, but I dont want to let my audience down.”“I know what to do,” said Hans. “I can give the lecture for you. You can trust me. Ive learnt it be heart. No one knows you at this university, so they wont find out.”So, they changed places. At the university, Hans was guided to the front of the hall. Einstein took a seat, listened to Hans give his lecture without difficulty, and joined in the applause at the end.However, before Hans left, a man shouted, “Id like to ask you a question.” He then asked a question so difficult that Hans had no idea what he was talking about.Einstein turned pale. “Oh no!” he thought. “Now were in trouble.” But Hans just laughed and said, “Thats such an easy question that even my driver can answer it. Hans, please.”Einstein stood up and answered the question perfectly.They left the university, with Einstein driving. A little later, Hans offered to drive. “No,” laughed Einstein. “Its a pleasure to drive a genius like you, Hans.”Unit 3 Family lifeIn this unit, you will learn about family life.Reading Family life in citiesPaula interviewed two teenagers for a programme on family life.She asked them some questions.Here are their answers.Emily(aged 15)1.
