Oscar R. Panno (born 1935 in
Buenos Aires) is an
Argentine chess Grandmaster.
Panno won the
World Junior Chess Championship in 1953, and also won the
championship of Argentina the same year. He became a
grandmaster at the age of twenty. He had an
Elo rating of around 2580 Elo in his prime, and of 2515 in 1986 and 2429 in 2008. Panno has several successes at the
tournaments at Mar del Plata. He won the international tournaments in 1954 and 1969 (shared with
Miguel Najdorf), and the open tournaments in 1986, 1988, and 1994. Panno tied for first at
Lone Pine 1977. He played various famous grandmasters, occasionally losing to them brilliantly. Panno was the first top world chess player born in
South America. He played eleven times for Argentina in
Chess Olympiads (1954–1958, 1962, 1966–1970, 1976, 1986–1988, 1992).
[1] He was still active as of 2008, finishing third in the
Bobby Fischer Memorial tournament held in
Villa Martelli.
Graciela Paraskevaidis (born 1 April 1940) is an
Argentine writer and composer of
Greek ancestry who lives and works in
Uruguay.
Miguel Samuel Spiro was born in
Hydra Island,
Greece. He emigrated to
Buenos Aires with his two brothers in 1810, and was an early supporter of the
May Revolution that year.
He had been a Navy Captain in Greece, and took part in organizing the fledgling naval forces of the
United Provinces of South America.
Spiro died on 28 March 1814 during a naval battle near
Concepción del Uruguay (Combat of Arroyo de la China), when he decided to scuttle his ship rather than surrender to the enemy.
The Argentine navy has named two ships in his honor, the most recent being the corvette ARA Spiro (P-43), commissioned in 1988.
Constantino Tsallis (
Greek: Κωνσταντίνος Τσάλλης; b. 1943) is a naturalized
Brazilian physicist working in
Rio de Janeiro at CBPF,
Brazil. He was born in
Greece, and grew up in
Argentina, where he studied physics at
Instituto Balseiro, in
Bariloche. In 1974 he received a
Doctorat d'Etat et Sciences Physiques degree from the
University of Paris-Orsay. He moved to
Brazil in 1975 with his family (his wife and daughter).
Tsallis is credited with introducing the notion of what is known as
Tsallis entropy and
Tsallis statistics in his 1988 seminal paper "Possible generalization of
Boltzmann–Gibbs statistics" published in the
Journal of Statistical Physics, vol. 52, pp. 479–487. The generalization is considered to be one of the most viable and applicable candidates for formulating a theory of non-
extensive thermodynamics. The resulting theory is not intended to replace Boltzmann–Gibbs statistics, but rather supplement it, such as in the case of anomalous systems characterised by
non-ergodicity or metastable states.
One of the most impressive experimental verifications of the predictions of
q-statistics concerns cold atoms in dissipative optical lattices. Eric Lutz made
an analytical prediction in 2003 which was verified in 2006 by
a London team.
