"Mulian Rescues His Mother" is a traditional Chinese story that is particularly well-known in the context of Chinese Buddhism. The tale revolves around Mulian (also known as Maudgalyayana), one of the Buddha's chief disciples, who is deeply concerned about the fate of his deceased mother. According to the story, after her death, Mulian discovers that his mother has been reborn in a realm of suffering due to her previous negative deeds.

Yoshinori Tokura is a Japanese physicist known for his work in condensed matter physics, particularly in the fields of spintronics and quantum materials. He has contributed significantly to our understanding of magnetic materials, topological insulators, and various phenomena related to electron spin and charge transport. Tokura's research has implications for advanced technologies, including the development of new electronic devices that leverage the unique properties of materials at the quantum level.

The Conway criterion is a mathematical concept used to determine whether a set of integers can be represented as sums of quadratic residues. It is particularly relevant in number theory and has applications in problems related to quadratic forms and modular arithmetic.

Isaac Israeli ben Joseph (circa 832–932) was a notable Jewish physician, philosopher, and one of the early figures in the development of Jewish thought and science during the medieval period. He was born in what is now Spain and later moved to North Africa, where he practiced medicine and engaged in intellectual pursuits. Israeli is particularly known for his works in philosophy and medicine.

Abraham ibn Ezra (1089–1164) was a prominent Jewish scholar, poet, and philosopher of the medieval period. Born in Spain, he later traveled extensively throughout Europe, including to France and Italy, where he became known for his contributions to various fields, including philosophy, astronomy, mathematics, and biblical exegesis. Ibn Ezra is well-known for his commentaries on the Hebrew Bible, which reflect his deep understanding of Jewish texts and his influences from both Jewish and Islamic thought.

The Free Will Theorem is a concept arising from the intersection of quantum physics and philosophy, formulated by physicists John Conway and Simon Kochen in 2006. The theorem explores the implications of quantum mechanics on the notion of free will and determinism.

Kisrhombille, also known as the kisrhombic dodecahedron, is a type of geometric structure classified as a polyhedron. Specifically, it belongs to a family of Archimedean solids, which are highly symmetrical, convex polyhedra composed of two or more types of regular polygons.

The 2022 World Jigsaw Puzzle Championship was a competitive event where puzzle enthusiasts from around the world gathered to compete in assembling jigsaw puzzles. This championship typically features individual and team competitions, where participants race against the clock to complete a given puzzle as quickly as possible. The event not only showcases skill and speed but also fosters a sense of community among puzzle aficionados.

The World Jigsaw Puzzle Championships is an annual competitive event that brings together puzzle enthusiasts from around the globe to compete in assembling jigsaw puzzles under timed conditions. Established in 2002, this championship typically involves teams or individuals racing against the clock to complete a specified jigsaw puzzle as quickly as possible. Participants are usually given a standard puzzle, and the competition is often structured in heats leading to a final where the fastest teams or individuals compete for titles and prizes.

"On Numbers and Games" is a book written by mathematician John H. Conway, published in 2001. The work delves into the field of combinatorial game theory, exploring how games can be analyzed mathematically. Conway introduces concepts such as surreal numbers and various types of games, including impartial games (where the allowed moves depend only on the state of the game and not on which player's turn it is) and partisan games (where the allowed moves depend on whose turn it is).

As of my last update in October 2021, there is no widely recognized figure or subject specifically known as "Yuri Trushin." It's possible that he may be a private individual, a lesser-known person, or a figure who has gained prominence after that date. If you are referring to a specific context or field (like science, sports, art, etc.

Conway notation is a system used in knot theory to represent knots and links. It was introduced by mathematician John Horton Conway in the 1960s. The notation provides a way to describe the structure of a knot through a sequence of symbols that represent crossings and their order. In Conway notation, the basic idea is to represent a knot using a sequence of letters and numbers that correspond to the crossings that occur when the knot is drawn on a plane.

The Von Neumann–Morgenstern utility theorem is a fundamental concept in decision theory and economics, particularly in the context of expected utility theory. It provides a framework for individuals to make rational choices under uncertainty. ### Key Elements of the Theorem: 1. **Rational Preferences**: The theorem assumes that individuals have preferences over risky prospects (lotteries) that can be represented in a consistent manner.

John Horton Conway was a distinguished mathematician known for his work in various fields, including combinatorial game theory, geometry, and number theory. Several concepts, theorems, and objects in mathematics and related fields have been named after him. Here is a list of some noteworthy items named after John Horton Conway: 1. **Conway's Game of Life**: A cellular automaton devised by Conway, which simulates the evolution of patterns based on simple rules.

As of my last update in October 2021, there isn't widely known information or significant public recognition of an individual named Gilbert Mair in connection with trading or finance. It is possible that he is a private trader or a less publicly recognized figure in the trading community, or he may have gained prominence after my last update.

Property-owning democracy is a political and economic concept that promotes the idea that a democratic society should ensure that all its citizens have access to property, particularly in the form of capital assets, which can provide individuals with economic independence and security. The idea is rooted in the belief that widespread property ownership can lead to a more equitable distribution of wealth and promote political participation and social stability. The concept is often associated with philosopher and economist John Rawls, particularly as articulated in his later works.

The social contract is a philosophical concept that explores the origins of societal organization and the legitimacy of political authority. It posits that individuals in a society collectively agree to form a government or state in order to ensure their mutual protection and welfare. This agreement often involves individuals relinquishing certain freedoms in exchange for security and the benefits of living in an organized community.

The IEEE John von Neumann Medal is an award established by the Institute of Electrical and Electronics Engineers (IEEE) to recognize outstanding achievements in the fields of computer and systems science and engineering. Named after the renowned mathematician and computer scientist John von Neumann, the medal honors individuals who have made significant contributions to the advancement of computing and related technologies.

John von Neumann, a pioneering mathematician and scientist, received numerous awards and honors throughout his career in recognition of his significant contributions to mathematics, computer science, and other fields. Here are some notable awards and honors associated with John von Neumann: 1. **National Medal of Science** (1963) - Awarded posthumously to recognize his contributions to science and technology.

**United States v. Texas (2021)** is a significant case concerning immigration policy that reached the U.S. Supreme Court. It primarily addressed a challenge brought by the state of Texas and other states against the Biden administration's attempts to rescind the Migrant Protection Protocols (MPP), also known as the "Remain in Mexico" policy.
