Aldo Pontremoli
Aldo Pontremoli (; 19 January 1896 – 25 May 1928) was an Italian physicist who held a chair of theoretical physics at the Milan school of physics, Physics Department of the University of Milan from 1926 and who founded and directed the Institute of Advanced Physics at the University of Milan from 1924 until his disappearance and presumed death in May 1928. Pontremoli was one of the six men who List of aerial disappearances, disappeared with the airborne envelope of the airship ''Italia (airship), Italia'' after it had crashed on the Arctic ice on 25 May 1928. Education Pontremoli was educated in a ''Lyceum, liceo'' in Milan, where Temistocle Calzecchi-Onesti was one of his teachers. After two years' further study at the Politecnico di Milano (Milan Polytechnic), he transferred to study physics at the Sapienza University of Rome, Università degli studi di Roma "La Sapienza". His studies were interrupted when he volunteered for military service in World War I. He received both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milan
Milan ( , , Lombard: ; it, Milano ) is a city in northern Italy, capital of Lombardy, and the second-most populous city proper in Italy after Rome. The city proper has a population of about 1.4 million, while its metropolitan city has 3.26 million inhabitants. Its continuously built-up urban area (whose outer suburbs extend well beyond the boundaries of the administrative metropolitan city and even stretch into the nearby country of Switzerland) is the fourth largest in the EU with 5.27 million inhabitants. According to national sources, the population within the wider Milan metropolitan area (also known as Greater Milan), is estimated between 8.2 million and 12.5 million making it by far the largest metropolitan area in Italy and one of the largest in the EU.* * * * Milan is considered a leading alpha global city, with strengths in the fields of art, chemicals, commerce, design, education, entertainment, fashion, finance, healthcar ...

Silver Medal Of Military Valor
The Silver Medal of Military Valor ( it, Medaglia d'argento al valor militare) is an Italian medal for gallantry. Italian medals for valor were first instituted by Victor Amadeus III of Sardinia on 21 May 1793, with a gold medal, and, below it, a silver medal. These were intended for junior officers or common soldiers who had distinguished themselves in combat. These medals fell into disuse during the period of Napoleonic domination. They were reinstated on 1 April 1815, by Victor Emmanuel I of Sardinia, who, however, abolished them only a few months later, on 4 August 1815, replacing them with the Military Order of Savoy (l'Ordine militare di Savoia), now known as the Military Order of Italy. However, in 1833, Charles Albert of Sardinia, recognizing that the Military Order was too exclusive in that it could only be awarded to persons of high rank, re-instituted the medals for valor (gold and silver) as awards for noble acts performed by soldiers in both war and peace.

Il Nuovo Cimento
''Nuovo Cimento'' is a series of peer-reviewed scientific journals of physics. The series was first established in 1855, when Carlo Matteucci and Raffaele Piria started publishing ''Il Nuovo Cimento'' as the continuation of ''Il Cimento'', which they established in 1844. In 1897, it became the official journal of the Italian Physical Society. Over time, the journal split into several sub-journals: * ''Nuovo Cimento A'' (1965–1999): Focused on particle physics. The journal ended when it was merged into the ''European Physical Journal'', in 1999. * ''Nuovo Cimento B'' (1965–2010): Focused on relativity, astronomy, and mathematical physics. As of 1 January 2011 it continues publication as the ''European Physical Journal Plus''. * ''Nuovo Cimento C'' (1978–present): Focuses on geophysics, astrophysics, and biophysics. * ''Nuovo Cimento D'' (1982–1998): Focuses on solid state physics, atomic physics, and molecular biology.

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though some perhaps semi-permanent gravel banks lie slightly clos ...

Cosmic Rays
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magnetic ...

Umberto Nobile
Umberto Nobile (; 21 January 1885 – 30 July 1978) was an Italian aviator, aeronautical engineer and Arctic explorer. Nobile was a developer and promoter of semi-rigid airships in the years between the two World Wars. He is primarily remembered for designing and piloting the airship ''Norge'', which may have been the first aircraft to reach the North Pole, and which was indisputably the first to fly across the polar ice cap from Europe to America. Nobile also designed and flew the ''Italia,'' a second polar airship; this second expedition ended in a deadly crash and provoked an international rescue effort. Early career Umberto Nobile was born in Lauro, in the southern Italian province of Avellino, into a family of small landowners. His father Vincenzo, a civil servant, belonged to the cadet branch of an aristocratic family that had been stripped of its titles after the Italian unification over their continuing loyalty to the deposed Bourbons, and which had adopted the Nob ...

Enrico Persico
Enrico Persico (August 9, 1900 – June 17, 1969) was an Italian physicist notable for propagating the field of quantum mechanics in Italy. He was a professor at the University of Turin and is also notable as the doctoral advisor of Ugo Fano. Career Persico was born in Rome on 9 August 1900. During his university years his friendship with Enrico Fermi intensified. He graduated in 1921. In 1926 he was already teaching physics at the University of Rome, and co-authored with Fermi on the topic of wave mechanics. He then moved to Florence, where he organized lectures on wave mechanics. At the end of 1930 he was called to Turin. From Turin he maintained relationships with Fermi. He was a witness to the discovery of the slowing down of neutrons and recorded results of the readings of the counters used by Fermi in order to measure the activity induced by neutrons in particles of silver, with and without the presence of paraffin. In the autumn of the 1949 Persico, discouraged from the op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
