The magnetic compass owes its success to the fact that it is a tool, as well as simple, practically autonomous.

He attended the Royal Technical Institute Ferdinando Galiani of Chieti graduated in 1909 and wishing to undertake engineering studies he moved to Turin enrolling in the Royal Higher Institute of Engineering which at the time represented the best in the field of mechanical engineering. He graduated in 1914 in mechanical industrial engineering at the Polytechnic of Turin.

In December 1914 he volunteered for the Corps of Engineers in the "Aviators Battalion" division.

participated in the First World War and went to the front to take care of the maintenance and surveillance of the material assigned to the flight squadrons

In January 1918 he moved to Indianapolis in the United States, [1] and traveled the roads in the field of the US aviation industry and formed an aviation company with the engineer Ugo Veniero D'Annunzio,. Upon his return he installed a civil and industrial engineering firm in Popoli, [1] where he had an intense planning activity for the private industry and in the public works sector.

In 1964 he signed a consultancy contract with the Agusta company that would lead to the design of a glider for training of helicopter pilots with the intention of spending much less than what it cost to train on a real helicopter. The project never reached the construction phase.

D'Ascanio died in Pisa on August 5, 1981, is buried in Popoli in the municipal cemetery in the family tomb, which he himself designed, alongside his wife Paola who died prematurely [20]. D'Ascanio had a great regret: he went down in history as the creator of the Vespa, but few remember that he was also a pioneer of helicopters.

 

His battery was composed by a column of zinc disks alternated with copper disks, with an intermediate layer of cardboard soaked in salt water.By connecting the two poles with an electrical conductor, a circuit was created in which direct current passed.

Born out of wedlock to a notary, Piero da Vinci, and a peasant woman, Caterina, in Vinci, in the region of Florence, Italy, Leonardo was educated in the studio of the renowned Italian painter Andrea del Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan, and he later worked in Rome, Bologna and Venice. He spent his last three years in France, where he died in 1519. Leonardo is renowned primarily as a painter. The Mona Lisa is the most famous of his works and the most popular portrait ever made.The Last Supper is the most reproduced religious painting of all time and his Vitruvian Man drawing is regarded as a cultural icon as well. Salvator Mundi was sold for a world record $450.3 million at a Christie's auction in New York, 15 November 2017, the highest price ever paid for a work of art. Leonardo's paintings and preparatory drawings—together with his notebooks, which contain sketches, scientific diagrams, and his thoughts on the nature of painting—compose a contribution to later generations of artists rivalled only by that of his contemporary Michelangelo.

Although he had no formal academic training,many historians and scholars regard Leonardo as the prime exemplar of the "Universal Genius" or "Renaissance Man", an individual of "unquenchable curiosity" and "feverishly inventive imagination.He is widely considered one of the most diversely talented individuals ever to have lived.According to art historian Helen Gardner, the scope and depth of his interests were without precedent in recorded history, and "his mind and personality seem to us superhuman, while the man himself mysterious and remote. Scholars interpret his view of the world as being based in logic, though the empirical methods he used were unorthodox for his time.  Leonardo is revered for his technological ingenuity. He conceptualized flying machines, a type of armoured fighting vehicle, concentrated solar power, an adding machine, and the double hull. Relatively few of his designs were constructed or even feasible during his lifetime, as the modern scientific approaches to metallurgy and engineering were only in their infancy during the Renaissance. Some of his smaller inventions, however, entered the world of manufacturing unheralded, such as an automated bobbin winder and a machine for testing the tensile strength of wire. He is also sometimes credited with the inventions of the parachute, helicopter, and tank.He made substantial discoveries in anatomy, civil engineering, geology, optics, and hydrodynamics, but he did not publish his findings and they had little to no direct influence on subsequent science.

D'Ascanio did not like motorcycles, he had never dealt with them from a constructive point of view and he did not like them as a vehicle. He thought of a vehicle for those who had never been on a motorcycle and hated his difficult driving, so he designed the Vespa.

The first model of the legendary motorcycle, the 98, made its official appearance in 1946 when it was exhibited at the cycle and motorcycle show in Milan and was immediately a success.

The "Vespa" model represented a commercial and custom phenomenon, both in Italy and abroad, which in addition to its function as a means of transport, would also have irreparably influenced cinema, inspiring them with a new message of 'freedom' and independence: memorable and Oscar-winning are the scenes from the film Roman Holiday of 1953, which see an Audrey Hepburn clinging to Gregory Peck's back riding a Vespa on the streets of Rome. To not

mention the influences that this invention also had on literature, inspiring a series of books where the Vespa is indicated almost as a 'cult object'.

Patented by Piaggio in 1946 and then produced the following year with a 100cc three-speed engine, the Vespa anticipating the definitive advent of the car, was in fact the means of the first mass motorization in Italy

In the 50 years of its history, the Vespa will become the most famous scooter in the world with 16 million units produced in 130 different models in 2005.
