We knew there had been many inventions at the last century, for example, electric light bulb, telephone, phonograph, mimeograph machine, automobile, airplane, atomic weapon, computer and so on.
What is my favorite invention?
Personally, my favorite invention should be computer.
In the old days, many scientists took much time to calculate and deal with research data, so the effective time in doing research was relatively shortened.
For millions of times of calculating per second by computer, the researchers may have enough time to study more important issues. The processing of experiment results became very simple and easy.
Arent those all evidences that the computer is one of the greatest inventions in the last century, are those?
So my favorite invention is computer.
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!Thats 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,dont you think its 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 dont you think books are better tempered and better get alongde than our real teachers?
I think 1847 is unusual,because Thomas Edison was born this year.Do you know him?He is one of the most famous persons all around the world.And his birthday is November 2nd.He started to go to school at the age of 8.
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,isnt 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 外教一对一英语价格贵不贵，roogge.com一年大概需要多少钱?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.Edisons mos其实我也是研究了很久关于线上英语培训机构的事情了www.jxwzhs点抗.com也去问了很多人的意见t 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.
