愛迪生一生中的發明超過二千多種。他不但成為近代物理史上一位相當傑出的科學家，更被譽為世界上最偉大的發明家。 愛迪生一生卓越的成就並非僥倖，而是他百折不撓、勇於嘗試、敢於創新的成果。愛迪生一生中最大的貢獻，就是發明了電燈。他做了 1600 多次耐熱材料和 600 多種植物纖維的實驗，才製造出第一個燈泡。後來他更在這基礎上不斷改良製造的方法。1882 年他在紐約建立了一個電力網。雖然他使用直流電 的輸電方法限制了傳送電力的距離，但這項偉大的貢獻，已大大改善了人類的生活。

Edison had over 2000 inventions in his life. He did not just become one of the best scientist, and he was also known as the best inventor. Edison's success did not come with luck, he got his success went through a lot of hard times, with his willingness to explore and try different things. The biggest contribution that he achieved was to create light bulbs. He had attempted 1600 times with different heat-resistant materials and over 600 plant fibers to make his first light bulb. Afterward he had further develop from this foundation. In 1882 he had established a power network. Although his direct current restricted the distant from transferring power, this huge contribution has brought a big improvment to human life.

Edison's invention exceeds more than 2,000 kinds in all his life.
He not only becomes a quite remarkable scientist in modern physics history but also is praised as the greatest inventor all of the world.
His success isn't getting by accident.
On the contrary, his achievement is due to his patience,trying new, and daring to innovate.
To invent the electric light is Edison's greatest contribution in all his life.
Just produce the first bulb, he has made the experiment with heat-resisting material in more than 1600 times and the experiments with more than 600 kinds of plant fiber.
Later on he is improving the method to reform constantly on the basis of this.
He sets up a electricity power network in New York in 1882
Though he uses the direct current transmission as an electricity method, it is to restraint the distance of the electricity transmission in the same time.
But this great contribution has already greatly improved human life.Source(s): Webster's、自己

Edison's invention in all one's life exceeds more than 2,000 kinds. He not only becomes a quite outstanding scientist in modern physics history, praised as the greatest inventor in the world even more. Edison, the remarkable achievement is not but he is indomitable , achievement dared to try , daring to innovate by sheer good luck in all one's life. Edison's greatest contribution in all one's life, but invented the electric light. He has made the heat-resisting material more than 1600 times and the experiments of more than 600 kinds of plant fibres, just produces the first bulb. Later on he is improving the method to make constantly on the basis of this. He set up a power network in New York in 1882. Though he uses the direct current transmission of electricity method to exercise restraint in conveying the distance of the electricity , but this great contribution, has already improved human life greatly .
