premier scientist pineers f the 20th century t be cmmitted t t be inspired by t be prpsed by t imprve the quality f human life
Read the text abut sme f the pineers in science during the 20th century. What discveries are mentined? Wh made them?
If yu had t chse the single mst imprtant discvery f the 20th century,yu wuld have a real prblem n yur hands. In just 100 years,the wrld has changed cmpletely. Amazing discveries were made in medicine,cmmunicatins and transprt,nt t mentin ur knwledge f the wrld and space. Medical advances ranged frm discvering the causes f diseases under micrscpes t staging peratins t replace diseased rgans with dnated nes. Cmmunicatins changed with the intrductin f mbile phnes,and the way we crrespnd went frm writing letters t emailing and sending instant messages. We started flying arund the wrld,launching satellites int rbit and,at the same time,scientists figured ut hw t split the atm,previusly thught t be the smallest particle f matter in the universe.Althugh it is impssible t chse the mst imprtant discvery,it is pssible t single ut a few pineers f the 20th century. Here are sme f them.
One f the 20th century’s premier scientists was Albert Einstein. In the summer f 1905,this utspken yung man was rcking his ne-year-ld baby when he was suddenly inspired. Subsequently, “E = mc²” was brn. It shwed hw a small piece f mass culd prduce an unbelievable amunt f energy. Einstein then shwed in his “thery f relativity” that nt even time,mass r length are cnstant—they change accrding t ur experience f them.In 1929,anther imprtant finding was made by bilgist Alexander Fleming. Befre he went n hliday,Fleming left a dish f bacteria in his labratry. When he came back,he nticed smething strange. He duble-checked and saw a blue muld in the dish arund which the bacteria had been destryed. This blue muld was in fact the natural frm f penicillin,which Fleming perceived culd be used t kill bacteria. A few years later,penicillin was being mass-prduced and helping t save the lives f millins. Fleming remained humble abut the amazing utcme f his discvery. “Nature made penicillin,” he said, I just fund it.”During Wrld War Ⅱ,when Fleming’s discvery was first helping t cure peple,the US Navy was lking fr ways f imprving the accuracy f their missiles. The navy turned t Eckert,an engineer,and Mauchly,a physicist,t deal with the prblem and prduce a machine t d the jb in a jint effrt.
Althugh they nly finished after the war in 1946,it did nt matter. This huge machine was the wrld’s first cmputer,but it was nthing like ur cmputers tday. It measured 100 feet lng by ver 10 feet high and weighed ver 30,000 kilgrams. With 18,000 tubes,thusands f circuits and 6,000 switches,it used s much energy that when it was turned n,the lights in the lcal twn went ut!With the develpment f cmputers,peple expected t get mre things dne efficiently. During the Cld War,a “huge netwrk” f cmputers was prpsed by tw American scientists. With cmputers talking t ne anther,it wuld enable gvernment leaders t cmmunicate with each ther. By the end f the 1960s,sme mini-netwrks were established,but nly a few cmputers culd cnnect t them. In 1990,Tim Berners-Lee invented the Wrld Wide Web,which enabled cmputers all ver the wrld t cmmunicate with each ther. Nwadays,life withut the Internet fr mst peple is unimaginable.These pineers f the 20th century were all dedicated t imprving the quality f human life n Earth. Human life n this planet has been transfrmed int a “glbal village”,with all the different cuntries linked in the chain f cmmn interests. There is n dubt abut it. Withut the breakthrughs f these pineers in science and technlgy,whether lucky r planned,the wrld as we knw it tday wuld be a cmpletely different place.
