Michael Faraday: Greatest Grandfather of Modern Electrical Chemistry

When we study the earlier life story of Michael faraday it is hard for people to believe that he has become a distinguished scientist in history. He was one of the greatest generators of modern electricity and he influenced and inspired thousands of veterans, including Einstein.

Renowned physicist Ernest Rutherford has said that when we think about the vastness of his inventions and the impact he has had on the development of science and industry, there is nothing like remembering Faraday, one of the greatest inventions of all time. We must say thanks to Faraday for modern electric motors, generators, and transformers.
Faraday was born on September 5, 1949, in Nuddington, England. He was born into a poor family. She was the third child of James and Margaret Faraday. His father, who was physically ill, was an iron smith. Faraday's mother was also a pre-maid servant. They were extremely poor.

At that time, parents had to pay their first child for an expensive schooling, and even then it was common practice for a young child. But Faraday's parents were of a normal family, with Faraday the third of four children. So he received a very limited and limited initial education. But that didn't hinder his way of becoming the greatest scientist of the future. She raised the learning curve for herself.

Michael Faraday attended local schools until the age of 3 and received basic education. From the age of six, he worked at a bookstore to help his poor parents. He worked hard and the bookstore made Sahu happy. A bookie who was happy with her hard work, promoted her to do bookbinding.

To get the book binding done for Faraday was like, 'You cheat, I'll deliver'. She was happy. It was also an opportunity for him to gain world knowledge. During the leisure hours he would read the three books he had been eagerly pursuing. Gradually, his interest in reading books related to science increased. He read many books on science. But among them his most favorite books were Encyclop ब्रिटdia Britannica and Conversion on Chemistry. While he acquired electronic knowledge from the Encyclopानdia Britannica, a four-page book called Conversation on Chemistry served to eradicate his curiosity and hunger for chemistry and to widen his horizons of knowledge.

How eager he was to read scientific material and to know its facts, a portion of his earnings was spent on chemicals to discover the reality of what he was reading.

One day while he was studying with a keen interest in science, he heard that then-renowned scientist Jose Tatum had come to give a series of discourses about natural philosophy under physics. The charge to hear the sermon was a ceiling, which was difficult for Faraday to pay. But his older brother, who was an iron maker himself, paid all the fees for listening to that sermon because of his brother's interest in science.

Another interesting turning point in Faraday's life came when one of his working bookstore clients, William Dance, saw Faraday's interest in science and arranged a ticket to hear a sermon by then-Humphrey Davies at the Royal Institute. What it looks like for Faraday is like Kana, the eyes.

Sir Humphrey Davy was one of the world-renowned scientists at that time. He took advantage of the opportunity provided by the Dance as a Client to listen to Davey's four sermons. His lecture was about 'explaining acidity', a new problem that appeared in the science world at that time. He took a serious look at Sir Davie's experiments during his sermon.

In fact, that was the dream world Faraday wanted to live. He notes Davie's sermon. He added so much to the note that it later became a six-page handwritten book. He made that note using his bookbinding skills and sent it to Sir Davey as a gift.

By this time, Faraday had begun to experiment a little more in the backyard of his working bookstore. He was using copper coins and zinc plates to separate electric paper and use it to make electric batteries. He used that battery to dissolve chemicals such as magnesium sulfate. This was a kind of chemistry that Sir Humphrey Davy had mastered.

On October 7, the owner of Faraday's bookstore changed. Faraday didn't like that new owner.

In the meantime, a new opportunity has come for Faraday. In fact, Sir Davie was injured when an experiment exploded. As a result, he was unable to write for some time. As a result, Faraday was able to write Davie's note for a few days. In fact, Sir Davey was impressed by the note Faraday sent earlier, and that is why he had the opportunity.

Soon Sir Davy was healed and Faraday had to take a break from writing notes. Meanwhile, Faraday, who was unaware of his new boss, was looking for work. In that regard, he sent a note to Sir Davey for work.

Faraday, who was influenced by Sir Humphrey Davy's studies and his scientific lectures, wrote him a letter of employment. At the time, Davey was the head of the laboratory at the Royal Institution and assistant lecturer in chemistry.

What happened to Faraday, however, was that shortly after he sent the note, Sir Davy's lab assistant was dismissed on the charge of misconduct. It was a matter of three. Faraday called on Sir Davie to work as an assistant in the laboratory.

Faraday immediately accepted that job. Being an assistant to one of the world-renowned scientists, working at the Royal Institute of Britain was an opportunity for Faraday to embark on an unimaginable and new way of life. When he got that opportunity, he started working at the Royal Institute on March 6, 8, just 2 years old.

Now a new turning point has come in Faraday's life. New and distinguished work, good pay. At the same time, the Royal Institute provided him with a living room.

Faraday spent six years of his life at the Royal Institute. After working as an assistant in the lab, he eventually became a chemistry professor.
His job as a lab assistant was to deliver the equipment for the lectures and experiments during that time. He also had to play with a chemical called nitrogen trichloride, which Davie had injured before the chemicals exploded. Faraday himself was once again unconscious due to the explosion of nitrogen chloride, and Davy was also injured again in the same sequence. For that reason, the use of that chemical was eventually discontinued.

During the seven months that Faraday was working at the Royal Institute, Davie took him on a six-month-long trip to Europe as his secretary.

So Faraday's relationship with Davy has not always been smooth. Due to his upbringing and the British caste system, Faraday was regarded as inferior and he was considered ineligible to be treated and treated with equal respect by his distinguished master.
Because of this, Faraday was not only required to work as Davie's science assistant during his travels to Europe, he also had to serve as Davie's personal assistant, dressing him, bearding and helping with other personal work. In addition, Davey's wife was cruel, and she would not allow Faraday to have food with her and travel with her in the bin.

On that visit, Faraday had the opportunity to meet world-renowned scientist Andrea Marie Emperor in Paris and Alessandro Volta in Milan. In fact, for Faraday it proved to be like an opportunity to study in a college of science touring Europe. From this he gained the opportunity to acquire many knowledge of science.


But after returning from London to Europe, the situation was back to normal. The Royal Institute renewed Faraday's contract and simultaneously raised his salary. Davy also began writing in his academic articles to Faraday: I am indebted to Mr. Faraday for his extremely capable support. “Indebted to Mr. Michael Faraday for much able assistance. ”

In 9 years of age, Faraday had the opportunity to give the first sermon of his life. He gave that sermon on the properties of matter in the City Philosophical Society. He then published his first academic article on the analysis of calcium hydroxycate in the Quarterly Journal of Science.

At age 89, he was promoted to the Royal Institute of Superintendents of the House and Laboratory. He married Sarah Sarah Bernad. Until then, he had been provided with a comfortable, luxurious and luxurious living room instead of the Royal Institute's Buiggle room, which was once occupied by Faraday's guru Davey himself.

Faraday married Sarah Bannard in 9, but they had no children. They were both committed Christians and were members of the Sandemanian Sect. Due to his poor health condition, Faraday rarely did research in the field of science.
Together with Davey, Faraday demonstrated his extraordinary talent and made some important inventions. He invented a liquid form of chlorine in the 8th and in the 8th he invented a new substance now known as benzene.

Faraday was without a doubt the most accomplished chemist, and he was also a Master of Electricity. In 9 Faraday invented a homopolar motor. His invention was influenced by the electromagnetism of Danish physicist Hans Christian Orstedt. Faraday called the electromagnetic rotation that the motor operates. This has become the main tenet of the current electric motor. Fareed by this invention, Faraday published his novel without giving it to Davey, the catalyst for his invention. As a result, the relationship between Faraday and Davey worsened. As a result, Faraday did no other achievement in the field of Electricity. The reason for this is that people believe that this is because of the angry Davy who assigned Faraday to another area of ​​research.

At the age of 6, he was elected to the Royal Society. It was an accepted and respected position in the sense that he had become an established scientist by the strength of his own abilities and talents. Shortly thereafter, he became the director of the Royal Institution Laboratory at the age of eight (2). Similarly, at the age of 4 he became a Fullerian Professor of Chemistry at the Royal Institute of Great Britain. He held this position for a lifetime.

He was twice proposed to become the president of the Royal Society in 1 and 2, but he declined.

In 8, he invented the electromagnetic index. It laid the foundation for modern electric generators and transformers. This invention revolutionized the use of electricity. His invention opened the door to limited general electricity access to labs and limited experiments so far.
In the meantime while doing these two wonderful inventions, he started a evening lecture and Christmas lecture at the Royal Institute where he worked. His popular lecture series continues today. Faraday's thinking was that it would make the public's access to scientific concepts more accessible and attract young people to science. After he did this, he himself, in his early life, was also deprived of such an opportunity.

Faraday survived until the 5th. This great scientist passed away on August 7 of that year.

Faraday wrote in a letter to a friend about how to lecture:

 'A flame has to be burned from the beginning and kept burning until the end.'

In fact, her words reflect her vision of life and how she lived.

Faraday was born into a poor family and later became one of the world's greatest scientists. His immense contributions and inventions in the field of science are also important in the sense that he made those inventions at a time when science was considered to be for wealthy and affluent families only. The unit of electrical capacitance is named Farad, which is an indication of F, in honor of his distinguished contribution to the field of science, especially in the field of electronic science.

What is the importance of chemistry in human life?

Chemistry is the branch of science in which the changes in the composition, structure, properties and chemical reaction of substances are studied. The human body itself is also made of chemical composition and the environment required for human life is also a mixture of chemical elements.

Chemistry is the branch of science in which the changes in the composition, structure, properties and chemical reaction of substances are studied. Human life can not be seen separately from chemistry, because living organisms, gas, liquid, solids and powders are made up of chemical elements only from the most humid minerals like diamonds and most hard minerals such as diamonds.

The human body itself is also made of chemical composition and the environment required for human life is also a mixture of chemical elements. The use of chemistry in day-to-day life is as follows:


Health

Ditol and phenyl etc., which are used to clean the body's wounds in the form of homicides and disinfectants, are actually chemical substances. Ditol is called chlorophyllinol. The doctor also cleans the wound with hydrogen peroxide before strapping it. Because of the genetic properties, iodine tincture is used for dressing in hospitals. Bleaching powder/calcium hypochlorite is used to clean the water sources and to clean the drains. Phenol is used in mouthwash making and dental work.

beauty product

Most cosmetics are currently manufactured by chemical substances, such as, in the polypalish, titanium oxide is used, cold-cream mineral oil is prepared by combining the perfume into a mixture of wax, water and borax, in the formation of powder Khadiya, Tailkam, Zinc Oxide, Smooth Soil, and Starch, etc. are mixed with others and lipsticks are manufactured from wax, wire Is by gas and oil |

Stationery items

The paper is made from pulp from the wood, and many types of raisins are inserted in it, by which the use of the undesirable material gets out of it and the pure cellulose is saved. Then remove it from bleaching powder and add it to the clay soil or starch. Is mixed. The graphite present in the pencil is also a corpus of carbon and it is soft and electrode conductor.

Photography

When a photo of an object is drawn, the light from the object falls on the lens of the film, and the chemical composition of the film on the film changes Vastu's negative. Later, positive pictures from the negative are taken from the sodium thiosulfate coated paper and are developed.

Soap and detergent

Soaps and detergents are a mixture of chemical compounds or compounds used for refining/washing. A mixture of soap sodium or potassium salts and fatty acids that does the cleaning process in water, while detergents also do the same thing but for washing/refining, it is better than soap because of the hardness of the water But there is no effect.

agricultural operation

Currently, the use of chemicals is increasing in agricultural work. Fertilizers and pesticides are chemical mixtures that increase the productivity of crops as well as save them from being destroyed. High yielding seeds are also produced by the chemical verbs. Fertilizers, pesticides and high yielding seeds were an important contribution in bringing the green revolution in India, which not only made the country self-reliant in food grains, but also the situation of food security has improved.

Industry and transport

In the textile industry, the metal industry, leather industry, petrochemical industry, etc. chemicals are used in any form. Crude oil, petrol, diesel, kerosene, etc. are separated by the chemical verb. CNG gas used in transport is also a chemical mixture. Leather processing, called tanning, is a chemical process.

In addition to these areas, chemistry plays an important role in the formation of weapons, the manufacture of utensils, etc. And its role in human life is increasing continuously.
