Life
Born at Parma, in 1824 he was appointed professor at the local University but was compelled to escape to France after taking part in the revolution of 1831. Parma is a City in the Italian region of Emilia-Romagna near Modena famous for its Architecture and the fine countryside around it The University of Parma ( Italian: Università degli Studi di Parma, UNIPR is one of the oldest universities in the world founded in the 11th century This article is about the country For a topic outline on this subject see List of basic France topics. In 1839 he went to Naples and was soon appointed director of the Vesuvius Observatory, a post that he held until 1848.

Work
Melloni's reputation as a physicist rests principally on his discoveries in radiant heat, made with the aid of the thermomultiplier, a combination of thermopile and galvanometer. A galvanometer is a type of Ammeter; an instrument for detecting and measuring Electric current. In 1831, soon after the discovery of thermoelectricity by Thomas Johann Seebeck, he and Leopoldo Nobili employed the instrument in experiments especially concerned with characteristics of (in modern language) black body radiation transmitted by various materials. Thermoelectricity ( Thermo - Electricity) refers to a class of phenomena in which a Temperature difference creates an Electric potential or an electric Thomas Johann Seebeck ( April 9 1770 &ndash December 10 1831) was a physicist who in 1821 discovered the Thermoelectric effect Leopoldo Nobili (1784 - 1835 was an Italian Physicist who invented a number of instruments critical to investigating Thermodynamics and Electrochemistry The Electromagnetic radiation emitted by a Black body.

He used an optical bench fitted with thermopiles, shields and light and heat sources, such as Locatelli's lamp and Leslie's cube, in order to show that radiant heat could be reflected, refracted and polarised in the same way as light. An optical table is a piece of equipment used for Optics Experiments and engineering. Sir John Leslie ( April 10, 1766 - November 3, 1832) was a Scottish Mathematician and Physicist best remembered Reflection is the change in direction of a Wave front at an interface between two different media so that the wave front returns into the medium from which Refraction is the change in direction of a Wave due to a change in its Speed. Polarization ( ''Brit'' polarisation) is a property of Waves that describes the orientation of their oscillations
His most important book, La thermocrose au la coloration calorifique (Vol. I. , Naples, 1850), was unfinished at his death.
He also studied the magnetism of rocks, electrostatic induction and photography. In Physics, magnetism is one of the Phenomena by which Materials exert attractive or repulsive Forces on other Materials. In Geology, rock is a naturally occurring aggregate of Minerals and/or Mineraloids The Earth's outer solid layer the ‘ Lithosphere Electrostatic induction is a redistribution of Electrical charge in an object caused by the influence of nearby charges Photography (fә'tɒgrәfi or fә'tɑːgrәfi (from Greek φωτο and γραφία is the process and Art of recording pictures by means of capturing
