Question: Which mathematician was born earlier, Yakov Sinai or Georgy Adelson-Velsky?
Context: Abraham the Monk was a monk who lived in a monastery on Mount Sinai in the Sinai desert.  He was born about the close of the sixth century, and became a convert to Judaism about 615.  As a Christian monk, he spent his life in penance and prayer.  Doubts as to the Christian dogma grew in his mind, and, after a prolonged struggle, he deserted his cell in the monastery on Mount Sinai and wandered North through the desert into the Land of Israel, finally reaching the city of Tiberias.  Here he submitted to circumcision and became a Jew, receiving the name Abraham, by which he was subsequently known. Veniamin Fedorovich Kagan (Russian: Вениами́н Фёдорович Ка́ган ; 10 March 1869 – 8 May 1953) was a Russian and Soviet mathematician and expert in geometry.  He is the maternal grandfather of mathematicians Yakov Sinai and Grigory Barenblatt. Eric Emil Schadt (born January 31, 1965) is an American mathematician and computational biologist.  He is Dean for Precision Medicine at the Icahn School of Medicine at Mount Sinai and Chief Executive Officer of Sema4, a spinout next generation health information company of the Mount Sinai Health System that provides advanced genomic testing and merges big data analytics with clinical diagnostics.  He was previously founding director of the Icahn Institute for Genomics and Multiscale Biology and chair of the Department of Genetics and Genomics Sciences at the Icahn School of Medicine at Mount Sinai.  Schadt’s work combines supercomputing and advanced computational modeling with diverse biological data to understand the relationship between genes, gene products, other molecular features such as cells, organs, organisms, and communities and their impact on complex human traits such as disease.  He is known for calling for a shift in molecular biology toward a network-oriented view of living systems to complement the reductionist, single-gene approaches that currently dominate biology to more accurately model the complexity of biological systems.  Schadt has also worked to engage the public, encouraging people to participate in scientific research and helping them understand privacy concerns around DNA-based information. Corinna Ulcigrai (born 3 January 1980, Trieste) is an Italian mathematician working on dynamical systems.  She obtained her Ph.D. in 2007 from Princeton University with Yakov Sinai as her thesis advisor.  She was awarded the European Mathematical Society Prize in 2012, and the Whitehead Prize in 2013.  She works at the University of Bristol, United Kingdom. Leonid Bunimovich is a Soviet and American mathematician, who specializes in dynamical systems.  He is known for discovery of a fundamental mechanism of chaos (hyperbolicity) in Dynamical systems, which is called mechanism of defocusing.  The most famous class of chaotic dynamical systems of this type Dynamical billiards are focusing chaotic billiards (e.g., the "Bunimovich stadium","Bunimovich flowers", etc.).  More recently he introduced so called Bunimovich mushrooms, which are visual examples of billiards with mixed regular and chaotic dynamics.  In many labs over the world were built experimental devices in the form of various Bunimovich billiards.  He received bachelor's degree in 1967 and PhD in 1973 from the University of Moscow.  His thesis adviser was Yakov G. Sinai.  In 1986 he was awarded Doctor of Sciences degree in "Theoretical and Mathematical Physics". Georgy Maximovich Adelson-Velsky (Russian: Гео́ргий Макси́мович Адельсо́н-Ве́льский ; name is sometimes transliterated as Georgii Adelson-Velskii) (8 January 1922 – 26 April 2014) was a Soviet and Israeli mathematician and computer scientist. Yakov Grigorevich Sinai (Russian: Я́ков Григо́рьевич Сина́й ; born September 21, 1935) is a mathematician known for his work on dynamical systems.  He contributed to the modern metric theory of dynamical systems and connected the world of deterministic (dynamical) systems with the world of probabilistic (stochastic) systems.  He has also worked on mathematical physics and probability theory.  His efforts have provided the groundwork for advances in the physical sciences. "Miniver Cheevy" is a narrative poem written by Edwin Arlington Robinson and first published in "The Town down the River" in 1910.  The poem, written in quatrains of iambic tetrameter for three lines, followed by a catalectic line of only three iambs, relates the story of a hopeless romantic who spends his days thinking about what might have been if only he had been born earlier in time. The Armenian inscriptions of Sinai refer to nearly 110 ancient Armenian inscriptions that were found in the Sinai Peninsula.  The Armenian inscriptions found in Sinai indicate an earlier pilgrimage before 919 and after the Islamic conquest.  The outcome of searches concluded that 113 inscriptions in the Armenian language were found in the Sinai peninsula, and 20 in the Georgian language.  The inscriptions dating back to the 5th century provide evidence of Armenians traveling to the holy land in large numbers, the second largest people to visit.  One source mentions nearly 400 people, and another with around 800 people.  The inscriptions give evidence of Armenians being among the pilgrims to Mount Sinai. Georgy Fotev (Bulgarian: Георги Фотев ) (born August 24, 1941) is a Bulgarian sociologist.  His scientific works are in the areas of theory and history of sociology and the disciplinary fields of modern sociology.  The focus of the research interests of G.Fotev is the nature of sociology as a multiple paradigm science.  Another major theme in the works of Georgy Fotev is the dialogue as a base and horizon of multiple paradigm sociology.  Georgy Fotev has publications in the fields of historical sociology, sociology of politics, ethnosociology, the crisis of legitimacy, sociology of values, etc.  His books "The long night of communism in Bulgaria" and "Bulgarian melancholy" throw light on the dramatic fate of the Bulgarian national society.  Georgy Fotev was Minister of Education and Science (1991 - 1992).  He is professor emeritus of New Bulgarian University.  In 2003 he was awarded the Distinguished Service Award from the American University in Bulgaria.
