Thomas Edison

To make a tinfoil phonograph, you will need a cylindrical object like a paper towel roll, a needle, tinfoil, and a cone-shaped object to act as a diaphragm. Attach the tinfoil to one end of the cylindrical object, then place the needle in the center of the tinfoil. Speak or sing into the diaphragm and the vibrations will be recorded on the tinfoil, creating a primitive sound recording.

Thomas Edison was home schooled. He also used the Detroit Public Library. He tried to read every book in the library. When he was unable to do that he read every book in the science and mathematics section and could work the math problems. After he read all the science and math books, he read as many of the remaining books as possible. He was familiar with thousands of books and could discuss them. He lacked formal education.

Inside his Menlo Park laboratory, Thomas Edison worked on various inventions and experiments, including developing the phonograph, the incandescent light bulb, and the motion picture camera. It was in this barn that he revolutionized the way we light our homes and paved the way for the modern entertainment industry.

Thomas Edison and his team made over 1,000 attempts before successfully creating a working light bulb. Edison famously said, "I have not failed. I've just found 10,000 ways that won't work."

1. Albert Einstein (Germany/Switzerland): Theory of relativity
2. Nikola Tesla (Serbia/Croatia): Alternating current (AC) electricity
3. Marie Curie (Poland/France): Radioactivity
4. Enrico Fermi (Italy): Development of the first nuclear reactor
5. Werner Heisenberg (Germany): Uncertainty principle in quantum mechanics

The first light pen was invented in 1955 by computer scientist Ben Gurley at the Royal Canadian Navy Tactical School. It was originally used as a pointing device for computers.

The phonograph was important because it revolutionized the way music could be recorded and played back, marking a significant advancement in audio technology. It allowed for music to be enjoyed in the home, changing the way people experienced and interacted with music. This innovation laid the foundation for the modern music industry and the development of subsequent audio technologies.

Thomas Edison created the light bulb to provide a practical and affordable source of artificial light. He wanted to find a way to improve upon existing methods of lighting, such as gas lamps and candles, in order to make lighting safer and more convenient for everyday use.

The 78 rpm (revolutions per minute) record was first introduced in 1898 by Emile Berliner.

Thomas Edison improved the design of the lightbulb. He patented a practical and commercially viable incandescent lightbulb in 1879, which played a major role in popularizing electric light and making it accessible for widespread use.

The best type of desk lamp depends on your needs. Consider factors like brightness, flexibility, energy efficiency, and style when choosing a desk lamp. LED desk lamps are popular for their energy efficiency and adjustable brightness levels.

No, Thomas Edison did not invent the refrigerator. The first practical and commercially successful refrigerator was invented by Oliver Evans in 1805. However, Thomas Edison did contribute many inventions and improvements to various technologies, such as the light bulb and the phonograph.

No, Thomas Edison did not invent the clock. He was known for inventing the phonograph, the incandescent light bulb, and the motion picture camera, among many other technological innovations.

William Crookes first discovered the x-ray effect, but he didn't investigate it. Tesla investigated the effect, but it was Röntgen who named them X and realized what was really happening.

Thomas Edison had his lab in Menlo Park, New Jersey. It was here that he conducted many of his famous experiments and inventions, including the development of the first practical light bulb.

Edison started what we called the current wars. He wanted to power the word with his Direct current motor which Edison could not work it properly. Telsa did made it work properly but Tesla's Alternate current motor is better. Edison started diffamation on Tesla. He electrified animals showing that his system is better which is was not.

Research shows that Edison had scientists working for him and Edison got the patents. Obiously he had envy towards Nikola Tesla.

One thing he was better that Tesla is the market strategies which he employed workers and then negleting the patents to be in their names. The only thing Edison invent for real, is the electric chair.

There is no concrete evidence that Thomas Edison actively hated Nikola Tesla. However, they had different approaches to electrical technology, leading to some rivalry. Edison preferred direct current (DC) while Tesla promoted alternating current (AC), which was more efficient. Their differences in business strategies and personalities likely contributed to their competitive relationship.

Thomas Edison did not invent the fluoroscope, which is a device used for X-ray imaging. The fluoroscope was actually invented by Thomas Edison's assistant, Clarence Dally, in 1896. Clarence Dally worked with Edison on X-ray technology and made improvements to the fluoroscope for medical applications.

Some modifications made to the light bulb include the introduction of the tungsten filament in 1904, which made bulbs more durable and efficient. LEDs were developed in the 1960s, providing even greater energy efficiency and longevity. More recent advancements include smart bulbs, which can be controlled remotely using technology.

Nikola Tesla is also known as a great inventor and many people say he was more brilliant than Edison was.

Edison is famous for inventing the phonograph, incandescent light bulb, cement making technology, motion picture camera, DC motors and electric power generation systems, battery and several other things we use every day and don't think much about. Tesla similarly invented radio, fluorescent light, AC motors and electric power generation systems. Both these men lived long lives, well into their 80s, at around the same time a century ago.

There are big differences between Edison and Tesla. The main one seems to be based on who got the credit for what. Many Tesla fans accuse Edison of having stolen much from Tesla who worked for Edison during his early years. They claim Edison was a thief and that he died a rich and powerful man surrounded by friends because he robbed Tesla and others like him. Meanwhile, Tesla died broke and miserable and lonely with his closest friends being wild pigeons he had enticed into his room at the Hotel New Yorker. Edison fans similarly suggest Tesla was a swindler who deceived investors into financing his ideas with promises he rarely kept. They suggest Tesla got his just rewards.

Both versions appear to be true. For example, Edison did not invent the light bulb. Joseph Swan was installing them in homes and landmarks in England years before Edison got his light bulb patented and working. Edison was buying out other people's patents and when Swan eventually sued Edison and won, Edison had to take him in as a partner in Edison's British company. Likewise, a deceitful Tesla managed to convince J.P. Morgan, the world's most powerful financier at the time, to finance his concept for wireless free electricity production under the guise of sending radio messages across the oceans and to and from ships at sea. Tesla was making artificial lightning with Morgan's money that was eventually cut off.

Edison and Tesla came to technological blows in the late 1800s when Tesla's AC (alternating current) power systems that are used all over the world today came into competition with Edison's DC (direct current) power systems. As it turns out, Tesla's system was the better one.

Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, there were several other inventors who also contributed to the development of the light bulb around the same time.

Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light.

Yes, you can create a simple battery by holding a copper tube and a steel tube in an acidic solution like lemon juice, which will generate a small electric current. By wiring this to a light bulb, you can light it up. This experiment demonstrates the principles of making a battery using dissimilar metals.
