The 1life of Isaae Newton Most of yau mo daubt no the stary of Newton and the falling apple and hor it led te his discovery of the lar of gravity， Bt hor aueh do you mnov beyond that3 Do you know what kind af nan this great scientist Wasy or where he stands in the history of science? If you don' t，or even if you do，read the following lesson. Teaae Nerton was born on christmas Dey，1642 be arey up in the Enelish eountryside From the very first Nevton wps very much interested in the mysteries of nature，One of the mst difficult scientifie problens of Nentom s day was about the auestion ofnotion Why did ohbjects mve? Scientists could see thet stones rolled dom hills bat wind bler leaves along the ground，and heavy objects fell to the earth when aopped After Copemnicus they bean to atnit that the aarth itsel mved ARere there lams that govern these various kinds of motion?”they asked themselves。The Greeks had belieyed there were differont rules for motion an earth and in space， and that there Were unmatunal poyeaonts on the surface of the earth Galileo ms the first person to shallenge this Gresk vien af motion This Italian Scientist was afollower of Copernicus， It didn' t make much sense to Galileo to have iffarent mules for mption on earth and in space_ jie made to important diseoveries, Firsty he showed that motion was not unmatural， On the contrary an objeet once motion would tend to continue in motion Second，Galileo worked out amathematical fommula for the motion of all objeets that fll to the earthv Galileo Norever did not explain ho all notion in the universe worked ch work hadbeen done sinee Copemicus toobserveand record the mvements in the solar system Tt remnined now for soe great mathematical nind to pll this work all together and ht the age of tentrthree lsaae Newton aved from Caabridae to his country home There his thoughts turmed to the problens of notion hs Nerton hinself later told be story，he Was sltting in the Barden one evening，thinking when he natioed falline apole_ The apple set hia to wondering about the apyenent of falling thlnga Teceurred tohim that the foree which oaused fruit to fall from trees worked muite as sell at greater distances Fron the center of the earth -- om top of buildings r even on top of mountains Perhaps，thought Nerton， this see foree reached out meh farther stil， even to the moon Was it this foree which kept the moon going around the earthy hnd if so could not the sane foree explain the mpvenents of the planets around the sn? Menton beban to seareh foramathematical expression of his iaoa. Ta 1669 Newton becaae prafassar of mathematics at Caxbridga，Three years later ie joined the Royal Soniety，The Royal Soeiety was a group of learned non from all ranehes ar seienee. Before lang Nerton began aeain to study the problems of motion he hadalready discovered the eesential idess bat it still reaained for him to solve he diffieult mathematical prohlens，At last he seened to have solved the main aiffieulties But he did mot publish his findings at once。 ，  only in 1687 did he at last publish his new theory，Newton' s great work，The Mathematical Principles of Natural Philosophy，marked the triumph of the Scientific Revolution。The very title is significant，Newton had found the mathematical prineiples，the scientific laws which gover
