Antonino Lo Surdo
Antonino Lo Surdo (4 February 1880 in Syracuse – 7 June 1949 in Rome) was an Italian physicist. He was appointed as professor of physics at the Istituto di Fisica in Rome in 1919; upon the death of Orso Mario Corbino in 1937, he became the director. Lo Surdo studied terrestrial physics, including seismology and geophysics; the 1908 Messina earthquake caused the death of his parents and other close relatives, except his brother. He contributed to the foundation of the Istituto Nazionale di Geofisica under the auspices of the Consiglio Nazionale delle Ricerche, when its president was Guglielmo Marconi. His name is remembered for the discovery (made independently by Johannes Stark) in 1913 of the effect on an electric field on the emission spectrum of a gas. This physical phenomenon is called the Stark-Lo Surdo effect in Italy (and is generally known outside Italy simply as the ''Stark effect''). The discovery of the effect was a remarkably important contribution to the developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The city is notable for its rich Greek and Roman history, Greek culture, culture, amphitheatres, architecture, and as the birthplace of the pre-eminent mathematician and engineer Archimedes. This 2,700-year-old city played a key role in ancient times, when it was one of the major powers of the Mediterranean world. Syracuse is located in the southeast corner of the island of Sicily, next to the Gulf of Syracuse beside the Ionian Sea. It is situated in a drastic rise of land with depths being close to the city offshore although the city itself is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orso Mario Corbino
Orso Mario Corbino (30 April 1876, Augusta – 23 January 1937, Rome) was an Italian physicist and politician. His younger brother was Epicarmo Corbino. He served as the minister for education in 1921 and as the minister for economy in 1921. He also served as professor in Messina (1905) and in Rome (1908). He is noted for his studies of the influence of external magnetic fields on the motion of electrons in metals and he discovered the Corbino effect. Corbino worked with Damiano Macaluso where they discovered the Macaluso-Corbino effect, a strong magneto-rotation of the plane of polarization observed at wavelengths close to an absorption line of the material through which the light is travelling. As director of the Institute of physics he was the supervisor of Enrico Fermi, Edoardo Amaldi, Franco Rasetti, Emilio Segrè, Bruno Pontecorvo, Oscar D'Agostino, Ettore Majorana, and Elena Freda.

1908 Messina Earthquake
The 1908 Messina earthquake (also known as the 1908 Messina and Reggio earthquake) occurred on 28 December in Sicily and Calabria, southern Italy with a moment magnitude of 7.1 and a maximum Mercalli intensity of XI (''Extreme''). The epicenter was in the Strait of Messina which separates Sicily from the Italian mainland. The cities of Messina and Reggio Calabria were almost completely destroyed and between 75,000 and 82,000 people died. It was the most destructive earthquake ever to strike Europe. Cause of the earthquake According to Italy's National Institute of Geophysics and Vulcanology, the earthquake was caused by a large, low-angle SE-dipping, blind normal fault, lying mainly offshore in the Strait of Messina, between plates. Its upper projection intersects the Earth's surface on the western, Sicilian side of the Strait. In 2019 researchers at Birkbeck, University of London discovered the active fault responsible for the earthquake. The study, led by Dr. Marco ...

Consiglio Nazionale Delle Ricerche
The National Research Council (Italian: ''Consiglio Nazionale delle Ricerche, CNR'') is the largest research council in Italy. As a public organisation, its remit is to support scientific and technological research. Its headquarters are in Rome. History The institution was founded in 1923. The first president was Vito Volterra, succeeded by Guglielmo Marconi. The process of improvement of the national scientific research, through the use of specific laws, (see Law 59/1997), affects many research organisations, and amongst them is CNR, whose "primary function is to carry on, through its own organs, advanced basic and applied research, both to develop and maintain its own scientific competitiveness, and to be ready to take part effectively in a timely manner in the strategic fields defined by the national planning system". On 23 December 1987, CNR registered the first Italian internet domain: cnr.it Reorganisation With the issuing of the legislative decree of 30 January 1999, n. ...

Guglielmo Marconi
Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi (; 25 April 187420 July 1937) was an Italians, Italian inventor and electrical engineering, electrical engineer, known for his creation of a practical radio wave-based Wireless telegraphy, wireless telegraph system. This led to Marconi being credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".Guglielmo Marconi: The Nobel Prize in Physics 1909 . nobelprize.org Marconi was also an entrepreneur, businessman, and founder of Marconi Company, The Wireless Telegraph & Signal Company in the United Kingdom of Great Britain and Ireland, United Kingdom in 1897 (which became the Marconi Com ...

Johannes Stark
Johannes Stark (, 15 April 1874 – 21 June 1957) was a German physicist who was awarded the Nobel Prize in Physics in 1919 "for his discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields". This phenomenon is known as the Stark effect. Stark received his Ph.D. in physics from the University of Munich in 1897 under the supervision of Eugen von Lommel, and served as Lommel's assistant until his appointment as a lecturer at the University of Göttingen in 1900. He was an extraordinary professor at Leibniz University Hannover from 1906 until he became a professor at RWTH Aachen University in 1909. In 1917, he became professor at the University of Greifswald, and he also worked at the University of Würzburg from 1920 to 1922. A supporter of Adolf Hitler from 1924, Stark was one of the main figures, along with fellow Nobel laureate Philipp Lenard, in the anti-Semitic ''Deutsche Physik'' movement, which sought to remove Jewish scientist ...

Stark Effect
The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is the electric-field analogue of the Zeeman effect, where a spectral line is split into several components due to the presence of the magnetic field. Although initially coined for the static case, it is also used in the wider context to describe the effect of time-dependent electric fields. In particular, the Stark effect is responsible for the pressure broadening (Stark broadening) of spectral lines by charged particles in plasmas. For most spectral lines, the Stark effect is either linear (proportional to the applied electric field) or quadratic with a high accuracy. The Stark effect can be observed both for emission and absorption lines. The latter is sometimes called the inverse Stark effect, but this term is no longer used in the modern literature. History The effect is named after the German physicist Johannes Stark, who discov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientists From Sicily
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

1880 Births
Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Fuscianus and Silanus (or, less frequently, year 941 ''Ab urbe condita''). The denomination 188 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
