Giuseppe Barilli (20 April 1812 – 18 December 1894), also known by his pseudonymQuirico Filopanti, was an Italianmathematician andpolitician.[1]
Barilli was born inBudrio, nearBologna, Italy, on 20 April 1812. He graduated in 1834 in mathematics and became professor ofmechanics andhydraulics in 1848.
He participated with the political affairs ofItalian unification, and during 1849 participated with the establishment of theRoman Republic. He was appointed secretary of the Assemblea Costituente (constituent assembly) and was the author of theDecreto Fondamentale ("Fundamental Decree") which on 9 February 1849 declared the temporal government of the Pope forfeited and proclaimed the Republic.
After the end of the Republic he found shelter in the United States and afterwards in London, United Kingdom. Even after the formation of theKingdom of Italy and his return to Italy, he ended his appointment as teacher ofmechanics at theUniversity of Bologna since he refused repeatedly to take his oath of allegiance to the monarchy. In 1876 he was elected as a member of the Parliament for theRepublican Party. He died poor in Bologna in 1894.
In his workMiranda in 1858 he develops the idea oftime zones. Filopanti's hypothesis was to ideally divide the Earth's surface into 24 areas (zones) along the lines of the meridians, each of which should have its own time. Each time zone should differ from the next by one hour, whereas minutes and seconds should coincide within each zone. The first time zone should be centred on Rome'smeridian. The division into time zones should establish the local time (L). His hypothesis provided also for the establishing of a universal time (U) that should be used as only datum line inastronomy andtelegraph communications.
Filopanti authored several books with peculiar titles, asCesar at the Rubicon (1847),On the Uses of Canvas in Hydraulics (1866),God Exists (1881),God is a Liberal (1880),Synopsis of the Geouranian Theory, or On Some Singular Relations Between the Earth and the Sky (1862). His bookMiranda. A Book Divided Into Three Parts, Entitled Souls, Numbers, Stars, on the Neo-Christian Religion, London, 1858, was listed byAugustus De Morgan in hisA Budget of Paradoxes.[2]
