Why Is Nick Jonas In The Hospital

Lazzaro Spallanzani


Scandiano Born in 1729, as in eight years, the clerical habit. Urged by his father to undertake the study of law, despite the innate inclination to the study of nature, in 1749-1750 he enrolled in law school at the University of Bologna. We grow the literature and a deeper knowledge of greek and French. Finally, unable to overcome resistance and paternal leave law firms to devote to those naturalistic. From 1757 to get the assignment for the 1762-1763 classes in physics and mathematics at the University Reggiana, founded by Francesco III d'Este 5 years ago.

In 1762, to refute the theory of spontaneous generation, he began research on "infusoria animals" and it is these experimental studies will start his scientific career, which will be marked by countless trips, travel, studies "on field, as suggested in his "Picciola memory on the way in which the Professor of Natural History of the Royal University of Pavia soles combine the systematic part of the science that teaches the spirit of observation".

The many hours hiking in the Apennines, hours in Como and the surrounding mountains, then to Genoa, the Riviera di Levante, in Marseille, on the Adriatic coast, and more in Portovenere, the Apuan Alps and Garfagnana, the Salsa and the oil wells of Montegibbio in Modena, in the Two Sicily, Mount Vesuvius, Etna and the Aeolian Islands, Spallanzani give the opportunity to get involved from time to time to the fauna of the sea, to stay focused on geological observations and mineralogical studies on the phenomenon of the electric torpedo, and geophysical observations Chemical studies on volcanic phenomena.
Even when the result of the excursions is not the publication of some scientific papers, the journey is still worthwhile to collecting material for the Museum of Pavia. During the study tour in Switzerland, made in 1779, the University and visit the many natural history collections of many scholars, and in that, by sea, in August of 1785 at a time of Constantinople, he studied the flora and fauna of the locations visited, make meteorological observations, is interested in costumes and life of those people. During the return on land collects boxes of minerals in some mines of Transylvania, in Salt Saltzbourg, and in the goldfields of argentiferous Zalatina, in the Erzgebirge region of the Carpathian, while a stop in Orbetello allows him to make remarkable observations on eels in the lagoon .

Spallanzani, who died in 1799, was a great biologist and physiologist, was interested in geology, mineralogy, chemistry and physics and had a great literary studies. His many discoveries made him a forerunner of more than a modern scientific discipline. He is best remembered for his research demonstrating the impossibility of spontaneous generation, digestion, reproduction and fertilization. For the latter showed the need for intimate contact of sperm with the egg and came to the realization of artificial insemination. Not least were the major discoveries on tissue respiration, the action of the juice gastric digestion of food and the mechanisms of blood circulation, and the presence of white blood cells.
