On this day (September 22), 1791, Michael Faraday was born, one of the most important scientists in history whom Einstein considered the origin of modern science.
Faraday received little formal education, he was one of the most influential scientists in history. At the age of 14 he apprenticed himself to George Riebau, a local Blandford Street bookbinder and bookseller. During his seven years of apprenticeship with Faraday he read many books, including Isaac Watts l and his on Improving the Mind , and became enthusiastic about the practice, principles and suggestions contained therein. He also developed an interest in science, especially electricity. Faraday was particularly inspired by the book Conversations on Chemistry by Jane Marcet.
In 1812, at the age of 20 and at the end of his apprenticeship, Faraday attended lectures by the eminent English chemist Humphry Davy of the Royal Institution and of the Royal Society, and of John Tatum, founder of the City Philosophical Society.
Faraday sent Davy a 300-page book based on notes he had taken during these lectures. Davy's response was immediate, friendly, and supportive. In 1813, when Davy damaged his eyes in an accident involving nitrogen trichloride , he decided to hire Faraday as his assistant.

Scientific achievements


Faraday's first chemical job was as an assistant to Humphry Davy . Faraday was specifically involved in the chlorine study ; discovered two new chlorine compounds and carbon .

Electricity and magnetism

Faraday is best known for his work on electricity and magnetism. His first recorded experiment was the construction of a voltaic cell with seven coins of British halfpenny , stacked together with seven rolled zinc discs and six pieces of paper moistened with salt water. With this battery he decomposed magnesium sulfate.

Faraday's concept of lines of flux emanating from charged bodies and magnets provided a way to visualize electric and magnetic fields; That conceptual model was crucial to the successful development of the electromechanical devices that dominated engineering and industry for the rest of the 19th century.


In 1845, Faraday discovered that many materials exhibit a weak repulsion from a magnetic field: a phenomenon he named diamagnetism .

Faraday cage

In his work on static electricity, Faraday's ice bucket experiment showed that charge resided only on the outside of a charged conductor, and that external charge had no influence on anything enclosed within a conductor.

As a curiosity to comment that during his life, he was offered a knighthood in recognition for his services to science, which he rejected for religious reasons, believing that it was contrary to the word of the Bible to accumulate wealth and seek worldly rewards, and declaring that he preferred to remain "Simple Mr. Faraday to the end".

- do you want to see my next presentation?
- ladies!
-no go ladies
- well... wait...
- ladies! Gentlemen!
- you're going to freak out!
- how?
- you're going to freak out!
- freak out?
- what's this about freaking out?
- freaking out is like impressing
- but what are you? scientist or clown?
- uh...scientist...
- then don't be a clown
- but it was to give more emotion
- go
