The Greatest Invention
Some articles hold the opinions that the greatest invention in the world is electricity,while the others believe computers are unreplaced in modern society.I read and read,suddenly an idea struke greatest invention are just books.
A famous person has ever said:"Books are the best teachers."Exactly!That's what I would like to say first.In the long history of human being,books have playde an important part in communicating knowledge.And even today,the situation is still so .Each year,millions of books are published in the world.Knowledge changs our lives.If a knowledged person want to express some new idea,probably he wiil choose to write a book.On the other hand,the best way to broaden our horizens is reading books.
Secondly,as I have been puzzled,books provedes you with different ideas.And you make your decision to choose anyone that fit you.Or otherwise,you may choose none of them,just like me ,instead of obeying books' advise.I choose "books" as the greatest invention in my eyes.So,don't you think it's a little interesting?Books are honored as teachers without sound.But how are books different from our real teachers?I think the fact is that,if a real teacher advises me to choose electricity or computer as my topic today,and every one you can imagine,how much brave I will prepare to refuse.So don't you think books are better tempered and better get alongde than our real teachers?

He sold newspapers on a train in 1859.And he began working early,he left home to work in different cities when he was only 18 years old.In 1869,he moved to New York to become an inventor.
I think he is very creative,because he could have 1903 inventions from 1868 to 1931.He is a talented inventor,isn't he?

In the early nineteenth century, people began to use gas ***gaslight***, but the gas pipeline supply by a leak or blockage, very easy to have an accident, people for illumination of reform, very ardent.In fact, Edison for himself set the mission impossible: in addition to improve lighting, but also of Thomas Edison electric light Create a set of power supply system.And he and the dream LuoYuan buddies, sleepless do 1600 repeatedly heat-resistant material and more than 600 plant fiber experiment, only produced the first carbon wire bulb, can a burning 45 hours.Later he more on this basis, the method of continuous improvement manufacture can ignite 12 hours finally came out with the ZhuSi bulbs.The 19th century the 1980s, Edison electric light career succeeded, this success than any previous achievements brought him reputation.In the 1980s, before he had little mistake, intermediate later, although he has made great achievements, but also common occurance of failure.Edison's most not commendable actions is one of his criticism alternating current, say it has side effects, likely cause of death and injury, but he did not add details.So somebody said, "as he such a mess out many inventions that people about others' new invention saurday attack, this is very contradictory things." He opposes the use of alternating current and direct current, so the approve a fierce debate and stubborn in failure.In this respect, reflects the Edison became a celebrity after the stubbornness of started to foster old-fashioned shortcomings.
19世紀初,人們開始使用煤氣燈***瓦斯燈***,但是煤氣靠管道供給,一但漏氣或堵塞,非常容易出事,人們對於照明的改革,十分殷切。事實上,愛迪生為自己訂定了一個不可能的任務:除了改良照明之外,還要愛迪生髮明的電燈創造一套供電的系統。於是他和夢羅園的夥伴們,不眠不休的做了1600多次耐熱材料和600多種植物纖維的實驗,才製造出第一個炭絲燈泡,可以一次燃燒45個鐘頭。後來他更在這基礎上不斷改良製造的方法,終於推出可以點燃1200小時的竹絲燈泡。19世紀80年代中期,愛迪生的電燈事業獲得了成功,這一成功比以往任何成就給他帶來的聲譽都大。在80年代中期以前,他很少有失誤,中期以後,儘管他也取得了很大成就,但失敗也是屢見不鮮的。愛迪生最不值得稱讚的行為之一就是他批
批評交流電,說它有副作用,可能造成死亡與損傷,但他未加具體說明。所以有人說,“像他這樣一個自己搞出了許多發明創造的人竟然對別人的新發明大加攻擊,這是很矛盾的事。” 他反對使用交流電而贊成直流電,因而在一場激烈而固執的論戰中敗北。在這方面,反映出了愛迪生成為名人之後漸漸滋生的頑固守舊的缺點。
