T NI T NI F 10 TASK 3 Find information about how the following things were invented/ discovered. Organise the information in your own way. Then describe the process in groups. E=mc2 Who? Significance? How? Significance? Albert Einstein inspired while rocking his baby showing how a small piece of mass could produce an unbelievable amount of energy theory of relativity penicillin Who? Significance? How? Significance? Alexander Fleming a lucky accident helping to save the lives of millions remained humble about the amazing outcome of his discovery computer Who? How? When? Eckert and Mauchly They did the job in a joint effort. It was the world’s first computer. Significance? In 1946 the Internet Who? Significance? How? Significance? Tim Berners-Lee different scientists working on it for many years enabling computers all over the world to communicate with each other without the Internet, life is unimaginable A brief introduction of scientific breakthroughs in the 20th century Some great pioneers of science and their inventions or discoveries The significance of these breakthroughs Para 1 Para 2-6 Para 7 Read the article again and answer the following questions. TASK 4 1. Which discovery or invention mentioned in the text has been the most important so far? Why? Example 1: I think the invention of World Wide Web has been the most important so far, because it is of great practical significance for most people. Life without it is unimaginable. 17 1. Which discovery or invention mentioned in the text has been the most important so far? Why? Example 2: I think penicillin has been the most important discovery so far because it has saved millions of lives around the world. For example, in WWII, many soldiers got wounded. Penicillin was useful in keeping wounds from getting infected and helping to speed the healing process of those wounds that did become infected. 18 2. Which discovery or invention will most influence the future? Why? Example 1: I think E=mc² will most influence the future. Because with the decreases in natural resources, energy problem has become more serious than ever. E=mc² provides theoretical basis for future research. 19 2. Which discovery or invention will most influence the future? Why? Example 2: In my opinion, the Internet will most influence the future. Without Internet, we might not immediately have access to the latest news or materials. For example, in the educational field, people share lessons and other educational resources on the Internet, which makes it possible for students in remote areas to get educated, and promotes fair education as well. 20 Line 12: Although...
