Thomas Edison

I think that he worked in the field of electrical engineering

I hope this helps

yes. well, sorta. it helped the start of all electricity. so if it wasnt invented, you wouldn't be able to use a computer, or atleast as fancy because it would be an earlier model because technology would be started later in life.

Well now that we have light we can see everything but without Thomas Edison's invention we can not see or do anything in the nightwithout light so thankyou Thomas Edison

he had 3 brothers and 3 sisters

Swan invented the light bulb in 1878. Edison spent a year trying to improve it and filed a patent in the US a year later. The two men never met but decided to settle out of court and formed the Ediswan company

Yes, Thomas Edison was an engineer in science.

Born in Milan, Ohio Edison lost much of his hearing at a young age and had very little schooling. He sold candy and newspapers to railroad passengers and set up a small lab for electrical experiments in a baggage car. Electricity in his time was mainly telegraphy and since he was around railroad stations where this took place it was natural for him to make telegraphy his life work. In 1868 he arrived in Boston where he became a full time inventor. The electrical shop of Charles Williams catered to inventors so it gave him ( Bell as well) a place to work with skilled workmen to put his ideas into practice In 1869 Edison moved to New York and in the next 20 years he and his workmen came up with invention after invention. His workshops invented the quadruplex telegraph, carbon button telephone transmitter, phonograph, electric light and a system of electrical generation and distribution More than a 1,000 patents bore name although most were not made by him personally. In Menlo Park, New Jersey he created a research and development center staffed with brilliant technicians and trained theoretical scientists.

When Edison was 14, he contracted scarlet fever. The effect of the fever, as well as a blow to the head by an angry train conductor, caused Edison to become completely deaf in his left ear, and 80 percent deaf in the other.

are you asking aboutthe light bulb in the sense of the the shape or the designand why it like that. that part i don't know.but if your askingabout who took partmeaning hands on, in constructing whatbecame a positiveresult, (when completed).iam sorry but i don't have your answer, i do have alittle insight on your question.what I do remember is Edison was a very determind head strong man, because he started with three assistance'stwo of them quit after a while, saying it can't be done, it just can't.the last one out of the three asst. wasabout to quit, he went into edisonsoffice and said sirexperiment # 176 faild, its not going to work, nothing works, we've tried everything, all this for nothing, Edison runs up to him andsays NO, NO! my sonits not for nothing,we've learned 176 ways that don't work. iam sorry i didn't know the names of the men who worked with Edison.justgena

he was a 发明家 (check google translate for the meaning in english)

Thomas Alva Edison lived and worked in Menlo Park, New Jersey, and was sometimes called the Wizard of Menlo Park.

on an early sunday morning on october 18th 1931

he invented it in 1899

The phonograph is a mechanical system.

Dirt in the groove on the disk will cause unwanted noise.

The disks are delicate and can be easily broken or damaged.

A needle (or stylus) has to touch the disk inside the groove, this can cause wear of the disk and diminish fidelity of subsequent playing.

The speed of the disk has to be regulated to get the right pitch of original recording.

Noise in the motor bearings can be transmitted through the disk and come out in the final sound.

Thomas Edison went to school only a few months. His teachers thought he was very slow. After this, his mother taught him at home, and he taught himself by reading constantly and trying experiments in the basement. He did not attend any technical school, college or university.

Thomas Edison's problem was that few homes and businesses could get electricity. He solved this problem by building a power plant that began supplying electricity to dozen of New York City buildings in September 1882.

Thomas Edison was famous for many devices that he developed and influenced life around the world. Some of these devices were the electric light bulb, motion picture camera and phonograph.

He didn't invent electricity, but a means to use it with things like the light bulb that differed from his closest competitor Tesla. No one invented electricity.

Light bulb simply provides vision and brightness to dark (evening) side of the world. Light bulbs turn a night into a day.

he discover light bulb by looking at the sun while he is resting.

worked on an panted sever on his most important invention including the metograph and automatic system such as quadraplex ,sextuplex and multiplex telegraph wich saved western union many millions of money in wiring
