Macedonio Melloni transformed the structure of the thermocouple on 11th August,1854

 

Today (August 11, 1854) is the Memorial Day of Macedonio Melloni, who transformed the structure of the thermocouple.

Today (August 11, 1854) is the Memorial Day of Macedonio Melloni, who transformed the structure of the thermocouple.

 

Macedonio Melloni was born on April 11, 1798, in Burma. Appointed professor at a local university. But after participating in the 1831 revolution, France was forced to flee. In 1839 he moved to Naples and was soon appointed director of the Vesuvius Laboratory. In 1845, he was elected a foreign member of the Royal Swedish Academy of Sciences.

 

A physicist who studied Melloni's infrared radiation or thermal radiation. His discovery, mainly in radiant heat, is made with the help of a thermomultiplier. It is a combination of a thermopile and a galvanometer. Modifier of the structure of the thermal electrode. In 1831, shortly after the discovery of thermoelectricity by Thomas Johann Seebeck, he and Leopoldo Nobili used the instrument in experiments involving the characteristics of black-body radiation transmitted by various instruments. He used an optical bench equipped with light and heat sources, such as thermobiles, shields, and Locatelli's lamp, and Leslie's cube, to show that he could reflect, refract, and polarize radiant heat just like light.

 

She also studied the magnetism, electrical induction and photography of rocks. Who made lenses using rock salt. He thus proved that heat rays can be concentrated and reflected just like teardrops. He has received the Rumford Medal of the Royal Society (1834), the Correspondent of the Academy des Science (1835), and the Foreign Society's Foreign Member (1839). Macedonio Melloni, who studied infrared radiation, died on August 11, 1854, in Portugal, near Naples, at the age of 56.
