Story of Michael Faraday | The Father of Electricity

Показать описание
In the second episode of 'Stories of the Great Minds', we talk about Michael Faraday, aka the architect of the modern world. This is the story of a man who didn't even enjoy half of the academic privileges that you have got access to but still went on to become one of the most celebrated scientists of his time, purely obliging to his curiosity.
On September 22,1791, little Michael was born to a poor family of a blacksmith in a small village named Newington Butts. Due to poor financial conditions, he along with his family used to face a lot of hardships. Sometimes, the whole family had to survive on a piece of the loaf for the whole week. These circumstances made Faraday not receive much formal education and eventually he had to finish school when he was just 13. A year later, he became an apprentice to Mr. Riebeau who was a local bookbinder and this is when and where Faraday found his passion. There he got to read a number of books, with the "Conversations on Chemistry by Jane Marcet" being his favorite one.
These books changed his life, they inspired him to explore further and further. Catering to his curiosity aroused by reading, he often went to attend lectures at the Royal Institution by eminent scientist Sir Humphrey Davy. Micheal made notes of all the lectures that Davy delivered, compiled them into a book of 300 pages, and presented them to him. Davy got so impressed with Faraday that in 1813 when Davy damaged his eyesight in an accident, he decided to employ Faraday as his assistant. This is how Faraday got a major break where he could now learn things form his idol himself.
With each passing day, new ideas struck Faraday's mind. Faraday discovered two new compounds of chlorine and carbon.
He invented an early form of the Bunsen burner and also discovered benzene which he called bicarburet of hydrogen. However, the first breakthrough discovery of his life took place in 1821. In 1821, Faraday showed that electrical energy can be converted into mechanical energy by performing experiments that now form the foundation of modern electromagnetic technology.
Faraday kept on experimenting with his ideas and eventually, another breakthrough in his life came 10 years later in 1831. This time he came up with his phenomenon of electromagnetic induction which not only established the relationship between electric current and magnetism but also served as a basic principle in the construction of the electric dynamo, the ancestor of modern power generators and the electric motor.
Faraday demonstrated that the charge resides only on the exterior of a charged conductor, and the exterior charge had no influence on anything enclosed within a conductor. This lead to the discovery of what we now call a Faraday cage. Not only this, "Faraday: the father of electricity", also made some noteworthy contributions in the field of diamagnetism, polymer chemistry, and electrochemistry. His experiments and inventions laid the foundations for scientific metallurgy and metallography.
For his remarkable contributions to science and society, Faraday earned numerous accolades in his lifetime. Faraday became the first and foremost Fullerian Professor of Chemistry at the Royal Institution. The SI unit of capacitance is named in his honor: the farad. Over the years, numerous great personalities have penned down heaps of appreciation for him.
Looking at all of his extraordinary achievements and brilliance, there's no doubt why Albert Einstein had kept a picture of Faraday on his study wall, alongside pictures of Isaac Newton and James Clerk Maxwell. Moreover physicist Ernest Rutherford also once stated; "When we consider the magnitude and extent of his discoveries and their influence on the progress of science and of industry, there is no honor too great to pay to the memory of Faraday, one of the greatest scientific discoverers of all time"
and we cannot agree more on this!
