THE GREATEST EXPERIMENTER OF ALL TIME

 MICHAEL FARADAY(1791-1867)

Michael Faraday(1791-1867)was one of the greatest scientists of the 19th century. From his experiments came devices that led to the modern electric motor, generator and transformer. It was largely due to his efforts that electricity became highly useful for day to day life.

EARLY YEARS 

Faraday was the son of a poor blacksmith, born in the village of Newington in Surrey, England. He started work as an apprentice bookbinder. Although Faraday received little formal education, he was one of most influential scientists in history.

HUMPHRY DAVY'S ASSITANTS

He became an assistant to the great scientists Humphry Davy. Michael Faraday was said to be Davy's greatest discovery.

BENZENE

Faraday discovered the important chemical benzene. Faraday drew huge crowds to his brilliant and entertaining Christmas lectures on science at the Royal Institutions in London.

FIRST PRIMITIVE ELECTRIC MOTOR

In 1821 Faraday showed that the magnetism created by an electric current would make a magnet move. Thus Faraday made the first primitive electric motor. 

THE FIRST DYNAMO

In 1831 Faraday showed that when a magnet moves close to an electric wire, it creates, or induces, an electric current in the wire. Faraday made the first dynamo to generate electricity and so opened the way to the modern age of electricity.

ELECTROCHEMISTRY

He laid the basis for electrochemistry, another great modern industry. Faraday coined many technical words like ion, electrode, cathode, and anode etc.

FARADAY CAGE 

A Faraday cage was discovered by Michael Faraday. Perhaps the most dramatic applications of Faraday cages is lighting safety in metallic cars or aircrafts. The metal shell of a microwave oven also acts as a Faraday cage and traps the microwaves inside the oven.

LEGANCY

His discoveries in electricity have continued to have a great influence on our daily lives. Albert Einstein kept a picture of Faraday on his study wall, alongside pictures of Isaac Newton and James Clerk Maxwell. Physicist Ernest Rutherford stated, "Faraday was one of the greatest scientific discoverers of all time".

THE GRACEFUL CREATURE OF THE SEAFLOOR

THE GRACEFUL CREATURE OF THE SEAFLOOR The sea pen is graceful creature of the seafloor; this sea pen resembles a plump, old-fashioned quill pen. Its colors range from dark orange to yellow to white. They live at many depths from shallow waters down to deep seas in tropical and temperate water worldwide. Each sea pen is a colony of polyps, small anemone like individuals working together for the survival of the whole. The primary polyp loses its tentacles and becomes the stalk of the sea pen with a bulb at its base. The bulb anchors the sea pen in the muddy or sandy bottom. They feed on phytoplankton and detritus particles. The red star, the leather star and the three types of Nudibranchs prey on sea pens. When touched, sea pens emit a bright greenish light; this is known as bioluminescence. when disturbed, a sea pen forces water out of the colony, making it possible for them to retreat into its bulbous foot. Recent research shows that the population of Sea pen has declined in some areas...

THE FORGOTTEN SCIENTIST

  NIKOLA TESLA Nikola Tesla was the famous scientist of 19th century. Nikola Tesla was born on 10th July 1856 in Smiljan, Austria (modern-day Croatia Southeast Europe). His father Milutin was a priest of the Serbian Orthodox Church. From early age, he could memorize entire books and store logarithms table in his brain. At the age of 19, he was studying electrical engineering at Polytechnic Institute at Gray in Austria. Tesla's general IQ was in a range from 160 to 200. Average Nikola Tesla IQ was 180. He made dozens of breakthrough in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success. In 1884, Tesla arrived in New York and was hired as an engineer at Thomas Alva Edison's Manhattan headquarters. After seeing his ingenuity, Edison told T...

AMAZING FACTS ABOUT INDIA

  AMAZING FACTS ABOUT INDIA  1. Tamil is the old and still surviving language in the world.  2. Tamil (more than 5000 years) oldest language in the world and it is the official language for millions of people in the world.
