Eliyahu Rips
Eliyahu Rips (; ; ; 12 December 1948 – 19 July 2024) was an Israeli mathematician of Latvian origin known for his research in geometric group theory. He became known to the general public following his co-authoring a paper on what is popularly known as Bible code, the supposed coded messaging in the Hebrew text of the Torah. Biography Ilya (Eliyahu) Rips grew up in Latvia (then part of the Soviet Union). His mother was Jewish and from Riga, the only of nine siblings that survived the war; the others were killed in Rumbula massacre, Rumbula and other places. His father Aaron was a Jewish mathematician from Belarus; his first wife, children, and all of his relatives were killed during the Holocaust. Rips was the first high school student from Latvia to participate in the International Mathematical Olympiad. In January 1969, he learnt from listening to Western radio broadcast — then illegal in the USSR — of the self-immolation of Czechoslovak student Jan Palach. On 13 April ...

Group Action (mathematics)
In mathematics, a group action of a group G on a set (mathematics), set S is a group homomorphism from G to some group (under function composition) of functions from S to itself. It is said that G acts on S. Many sets of transformation (function), transformations form a group (mathematics), group under function composition; for example, the rotation (mathematics), rotations around a point in the plane. It is often useful to consider the group as an abstract group, and to say that one has a group action of the abstract group that consists of performing the transformations of the group of transformations. The reason for distinguishing the group from the transformations is that, generally, a group of transformations of a mathematical structure, structure acts also on various related structures; for example, the above rotation group also acts on triangles by transforming triangles into triangles. If a group acts on a structure, it will usually also act on objects built from that st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the IMU Abacus Medal (known before 2022 as the Nevanlinna Prize), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

Aliyah
''Aliyah'' (, ; ''ʿălīyyā'', ) is the immigration of Jews from Jewish diaspora, the diaspora to, historically, the geographical Land of Israel or the Palestine (region), Palestine region, which is today chiefly represented by the Israel, State of Israel. Traditionally described as "the act of going up" (towards the Jerusalem in Judaism, Jewish holy city of Jerusalem), moving to the Land of Israel or "making aliyah" is one of the most basic tenets of Zionism. The opposite action – emigration by Jews from the Land of Israel – is referred to in the Hebrew language as ''yerida'' (). The Law of Return that was passed by the Knesset, Israeli parliament in 1950 gives all diaspora Jews, as well as their children and grandchildren, the right to relocate to Israel and acquire Israeli citizenship on the basis of connecting to their Jewish identity. For much of Jewish history, their history, most Jews have lived in the diaspora outside of the Land of Israel due to Jewish militar ...

Warsaw Pact Invasion Of Czechoslovakia
On 20–21 August 1968, the Czechoslovak Socialist Republic was jointly invaded by four fellow Warsaw Pact countries: the Soviet Union, the Polish People's Republic, the People's Republic of Bulgaria, and the Hungarian People's Republic. The invasion stopped Alexander Dubček's Prague Spring liberalisation reforms and strengthened the authoritarian wing of the Communist Party of Czechoslovakia (KSČ). About 250,000 Warsaw Pact troops (afterwards rising to about 500,000), supported by thousands of tanks and hundreds of aircraft, participated in the overnight operation, which was code-named Operation Danube. The Socialist Republic of Romania and the People's Republic of Albania refused to participate. East German forces, except for a small number of specialists, were ordered by Moscow not to cross the Czechoslovak border just hours before the invasion, because of fears of greater resistance if German troops were involved, due to public perception of the previous German oc ...

Jan Palach
Jan Palach (; 11 August 1948 – 19 January 1969) was a Czech student of history and political economics at Charles University in Prague. His self-immolation in 1969 at age 20 was a political protest against the end of the Prague Spring resulting from the Warsaw Pact invasion of Czechoslovakia in 1968 by the Warsaw Pact armies. Early life Palach was born in and attended elementary school in Všetaty, where he was an avid reader of Jules Verne. He was an average student. His father died when Palach was 13 years old and Palach was raised in part by his grandfather. His brother, Jiří, was 7 years older. In 1963, Palach began studies at a gymnasium in Mělník. He graduated in 1966 and unsuccessfully applied to Charles University. He then attended Prague School of Economics but in September 1968, he transferred to the philosophy faculty at Charles University, where he studied history and political economics. In the summer of 1967, Palach worked on a chicken farm in the Sovie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-immolation
Self-immolation is the act of setting oneself on fire. It is mostly done for political or religious reasons, often as a form of protest or in acts of martyrdom, and known for its disturbing and violent nature. Etymology The English word '' immolation'' originally meant (1534) "killing a sacrificial victim; sacrifice" and came to figuratively mean (1690) "destruction, especially by fire". Its etymology was from Latin "to sprinkle with sacrificial meal ( mola salsa); to sacrifice" in ancient Roman religion. In the Mewar region of India, women practiced a form of self-immolation called '' Jauhar'' to avoid being raped by invading armies. Effects Self-immolators frequently use accelerants before igniting themselves. This, combined with the self-immolators' refusal to protect themselves, can produce hotter flames and deeper, more extensive burns. Self-immolation has been described as excruciatingly painful. Later the burns become severe, nerves are burnt and the self-immolat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Mathematical Olympiad
The International Mathematical Olympiad (IMO) is a mathematical olympiad for pre-university students, and is the oldest of the International Science Olympiads. It is widely regarded as the most prestigious mathematical competition in the world. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980. More than 100 countries participate. Each country sends a team of up to six students, plus one team leader, one deputy leader, and observers. Awards are given to approximately the top-scoring 50% of the individual contestants. Teams are not officially recognized—all scores are given only to individual contestants, but team scoring is unofficially compared more than individual scores. Question type The content ranges from extremely difficult algebra and pre-calculus problems to problems in branches of mathematics not conventionally covered in secondary or high school and often not at university level either, such as projective and complex geo ...
