Thomas Edison

A phonograph is a device that plays sound recordings using a needle and a rotating disc or cylinder. It typically has a large horn to amplify the sound, a turntable for the disc or cylinder, and a needle or stylus to read the grooves on the recording medium. Phonographs were popular in the early 20th century before being replaced by more modern audio playback devices.

The vacuum pump was the critical precursor to the invention of the hot-filament light bulb. Indeed, improvements in vacuum pumps have continuously resulted in improvements in incandescent light bulbs.

And of course, such things as metal working, glass working etc.

No, Thomas Alva Edison did not invent the penny farthing bicycle. The penny farthing bicycle was invented by Eugene Meyer in 1869. Edison is known for his inventions in the field of electricity, such as the phonograph and the electric light bulb.

Thomas Edison invented the first practical incandescent light bulb and the phonograph. William Dickson, a collaborator of Edison, is known for inventing the first motion picture camera, called the Kinetograph, along with the Kinetoscope for viewing motion pictures.

Sir Joseph Swan's incandescent light bulb could last for about 40 hours before burning out. This was a significant improvement over earlier versions, but still not as long-lasting as modern light bulbs.

Thomas Edison was supplying electricity in New York with direct current. Those systems were bad causing fires and other hazards like electrocution in homes. When Nikola Tesla arrived to New York, he began working for Thomas Edison.

The first task assigned to him was fixing his direct current motor a a prize of $50,000. When he finished that, Edison didn't kept his world so Tesla walked out the place never to return.

Later in life, his alternate current beat Edison's direct current system and it was chosen for the 1893 fair. Edison in envy put in court that Tesla couldn't use his bulbs. So the Westinghouse co. made the bulbs for the fair.

Edison and Einstein never met in person. Edison was significantly older than Einstein, and Einstein did not immigrate to the U.S.A. until 1933, two years after Edison had passed away. For perspective, in 1879, when Einstein was born, Edison had just perfected the first practical Incandescent light.

Thomas Edison did not invent the light bulb on his own. While he is commonly credited with its invention, he built upon the work of many other inventors who came before him, such as Joseph Swan. Edison's key contribution was to develop a practical and commercially viable incandescent light bulb.

Edison was working on an direct current motor when Tesla began working for him. He couldn't make it work properly and he offered 50 thoundands dollars if he could fix the machine. That was a easy job for Tesla. Once he finished it, Edison took the offer back stating that it was a joke. Tesla took off inmediatly. The next thing Edison did, he took the patent for the direct current motor.

Albert Einstein did not invent the light bulb. The light bulb was actually invented by Thomas Edison in 1879. Einstein was a physicist known for his theories of relativity and his work on the photoelectric effect, but he did not invent the light bulb.

Thomas Edison created the first commercially practical incandescent light bulb in 1879. He improved upon existing designs to create a longer-lasting bulb that could be mass-produced and widely used for practical purposes.

Thomas Aquinas tried to reconcile faith and reason, incorporating the teachings of Aristotle into Christian theology. He also aimed to reconcile the relationship between natural law and divine law, arguing that both are necessary for a well-ordered society.

Thomas Edison's light bulb was invented as a way to provide a reliable and efficient source of light. It played a crucial role in replacing gas lamps and candles, revolutionizing indoor and outdoor lighting in homes, businesses, and streets. Edison's invention paved the way for the widespread adoption of electric lighting in the late 19th and early 20th centuries.

Edison had a direct current generator that he could not work it properly. Tesla begun working for him. He was offered money to correct the equipment and he did in a short period of time. Edison was not man of his work so Tesla quit working for him. He got the patent of the direct current generator which without Tesla's help, he would not got it along with many patents he got which is the result of his employees he had at the time.

Read the article I posted in the related links box below called the genius and the jerk.

Since the 1870s, Edison began his campaign against Nikola Tesla.

Second response. Thomas Alva Edison was the greatest inventor of all time. His 1,000 plus patents are an indication of Edison's brilliance.

The shape of a light bulb can affect its light distribution and overall appearance. For example, a globe-shaped bulb may provide more diffuse lighting, while a spotlight-shaped bulb may direct light more narrowly. Additionally, different shapes can affect how a bulb fits into various fixtures or lamps.

There is no such thing as a time machine. Edison was active in the movie business- but somewhat oddly, did not specialize in Science Fiction- after all we have thoroughly practical power companies, phonographs,. etc why stain things with frivolity. again, in the normal context of the word- there ain"t no such apparatus.

yes, we can

as we all know convex lens is a diverging lens,so,it diverges the rays of the sun .When the lens is placed over a paper,it diverges the rays,as a result of which paper burns

Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, it's important to note that several inventors, including Sir Joseph Swan, also played a role in the development of the light bulb.

Thomas Edison did not invent the kinetophone. The kinetophone was actually developed by Thomas Edison's competitor, Thomas Armat, in collaboration with C. Francis Jenkins in 1894. It was an early motion picture sound system that synchronized sound with moving pictures.

Thomas Edison tried to solve the problem of providing a practical and affordable way to deliver electricity to the masses. He developed the first commercially viable light bulb and worked on creating a system of power generation and distribution. Edison's inventions paved the way for the widespread adoption of electric power and helped revolutionize modern living.

The first national competition held at Rehoboth Beach in 1880 that Thomas Edison was a judge for was a sand sculpting contest called the "Sand Modeling Contest." Edison was brought in as a judge due to his popularity and reputation as a renowned inventor and public figure.

Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879.

Edison's lab developed the phonograph as a sort of accidental side project while working on the telephone. For most of the time he was perfecting it, he had absolutely no idea what practical purpose it could serve. So it was not an invention that came forth out of a real need for storage and reproduction of sound, but rather it came forth out of pure happenstance and research.

Thomas Edison's greatest fear was reportedly the dark. He was known to be afraid of the dark, which is ironic given his inventions revolutionized the use of light.
