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 me:The 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 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(jì)初，人們開(kāi)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(duì)于照明的改革，十分殷切。事實(shí)上，愛(ài)迪生為自己訂定了一個(gè)不可能的任務(wù)：除了改良照明之外，還要愛(ài)迪生發(fā)明的電燈創(chuàng)造一套供電的系統(tǒng)。于是他和夢(mèng)羅園的伙伴們，不眠不休的做了1600多次耐熱材料和600多種植物纖維的實(shí)驗(yàn)，才制造出第一個(gè)炭絲燈泡，可以一次燃燒45個(gè)鐘頭。后來(lái)他更在這基礎(chǔ)上不斷改良制造的方法，終于推出可以點(diǎn)燃1200小時(shí)的竹絲燈泡。19世紀(jì)80年代中期，愛(ài)迪生的電燈事業(yè)獲得了成功，這一成功比以往任何成就給他帶來(lái)的聲譽(yù)都大。在80年代中期以前，他很少有失誤，中期以后，盡管他也取得了很大成就，但失敗也是屢見(jiàn)不鮮的。愛(ài)迪生最不值得稱贊的行為之一就是他批
批評(píng)交流電，說(shuō)它有副作用，可能造成死亡與損傷，但他未加具體說(shuō)明。所以有人說(shuō)，“像他這樣一個(gè)自己搞出了許多發(fā)明創(chuàng)造的人竟然對(duì)別人的新發(fā)明大加攻擊，這是很矛盾的事。” 他反對(duì)使用交流電而贊成直流電，因而在一場(chǎng)激烈而固執(zhí)的論戰(zhàn)中敗北。在這方面，反映出了愛(ài)迪生成為名人之后漸漸滋生的頑固守舊的缺點(diǎn)。
