【正文】 thi s di sease into their bodi es wi th their meal s. From the stomach the di sease quickly attacked the body and soon the affected person di ed. John Snow suspected that the second theory was correct but he needed evi dence. So when another outbreak hi t London i n 1845, he was ready to begi n hi s enquiry. As the di sease spread qui ckl y through poor neighborhods, he began to gather i nform ati on. In two parti cul ar streets, the chol era outbreak was so severe that more than 500 peopl e died in ten days. H e was determi ned to fi nd out why. Fi rst he m arked on a m ap the exact pl aces where al the dead peopl e had li ved. This gave him a val uabl e cl ue about the cause of the di sease. Many of the deaths were near the water pump i n Broad Street (especi al ly num bers 16, 37, 38 and 40) . H e al so noti ced that som e houses (such as 20 and 21 Broad Street and 8 and 9 Cam bri dge Street) had had no deaths. H e had not foreseen this, so he m ade further i nvestigati ons. H e di scovered that these peopl e worked in the pub at 7 Cam bri dge Stret. They had been gi ven fre beer and so had not drunk the water from the pum p. It sem ed that the water was to bl am e. N ext, John Snow looked i nto the source of the water for these two streets. H e found that it cam e from the ri ver pol luted by the dirty water from London. H e imm edi atel y tol d the astonished peopl e in Broad Stret to remove the handl e from the pum p so that it coul d not be used. Soon afterwards the disease slowed down. H e had shown that cholera was spread by germ s and not in a cl oud of gas. In another part of London, he found supporti ng evidence from two other deaths that were li nked to the Broad Street outbreak. A wom an, who had moved away from Broad Stret, l iked the water from the pum p so m uch that she had i t del ivered to her house every day. Both she and her daughter died of cholera after drinking the water. Wi th this extra evi dence John Snow was abl e to announce wi th certai nty that pol uted water carri ed the virus. To prevent this from happening agai n, John Snow sugested that the source of al the water suppli es be exami ned. The water pani es were i nstructed not to expose peopl e to pol uted water any m ore. Fi nal y “Ki ng Chol era” was defeated. COPERNICUS’ REVOLUTIONARY TH EORY Ni col aus Coperni cus was frightened and hi s mi nd was confused. Although he had tri ed to i gnore them , al l hi s m athem atical calcul ati ons l ed to the sam e conclusi on: that the earth was not the centre of the sol ar system . O nl y if you put the sun there did the m ovem ents of the other plas i n the sky m ake sense. Yet he could not tel anyone about hi s theory as the powerful Christi an Church woul d have puni shed him for even suggesti ng such an i dea. They bel i eved God had made the worl d and for that reason the earth was speci al and m ust be the centre of the solar system. The probl em arose because astronom ers had noti ced that som e pl as i n the sky seemed to stop, move backward and then go forward i n the l op. Others appeared bri ghter at times and l ess bri ght at others. Thi s was very strange if the earth was the centre of the solar system and al plas went round i t. Coperni cus had thought l ong and hard about these probl em s and tri ed to fi nd an answer. He had col lected observati ons of the stars and used al his mathem ati cal knowledge to expl ai n them. But only hi s new theory coul d do that. So between 1510 and 1514 he worked on i t, gradual y improvi ng his theory until he fel t it was plete. In 1514 he showed it privately to his fri ends. The changes he m ade to the ol d theory were revol uti onary. H e pl aced a fixed sun at the centre of the solar system wi th the plas goi ng round i t and only the m oon stil going round the earth. H e al so suggested that the earth was spi nni ng as i t went round the sun and this expl ai ned changes in the movement of the pl as and i n the brightnes of the stars. Hi s fri ends were enthusi astic and encouraged him to publish his i deas, but Copernicus was cauti ous. He di d not want to be attacked by the Christi an Church, so he only publ ished it as he lay dyi ng i n 1543. Certainl y he was right to be careful . The Christi an Church rejected his theory, sayi ng i t was agai nst God’s idea and peopl e who supported i t would be attacked. Yet Copernicus’ theory i s now the basis on which al our i deas of the universe are built. His theory replaced the Chri stian i dea of gravity, which sai d thi ngs tel l to earth because God created the earth as the centre of the uni verse.
