P-boxes (probability boxes) and probability bounds analysis are powerful tools in the field of uncertainty quantification and risk assessment. They provide a systematic way to characterize and handle uncertainties in various applications, particularly when precise probability distributions are difficult to obtain.
An "appeal to probability" is a type of logical fallacy that occurs when someone assumes that because something is possible or likely, it must be true or will happen. This fallacy involves an unwarranted conclusion based on the probability of an event, rather than on solid evidence or deductive reasoning. For example, someone might argue, "It's likely that it will rain tomorrow, so it will rain.
The Law of Averages is a principle that suggests that over a large enough sample size, events will statistically tend to average out. In other words, it implies that if something happens with a certain probability, over time and numerous trials, the outcomes will reflect that probability.
The Yangian is an important algebraic structure in mathematical physics and representation theory, particularly related to integrable systems and quantum groups. It was first introduced by the physicist C.N. Yang in the context of two-dimensional integrable models. ### Key Aspects of Yangians: 1. **Quantum Groups**: The Yangian can be seen as a kind of quantum group deformation of classical symmetries.
Gambler's ruin is a concept from probability theory and statistics that models a gambling scenario where a gambler continues to gamble until either they lose all their money or reach a predetermined target amount. It is often used to illustrate the principles of random walks and the behavior of stochastic processes. In a typical setup, a gambler starts with a certain amount of capital and bets on a game with a fixed probability of winning or losing.
Neso is a natural satellite of the planet Neptune. It was discovered in 1989 by astronomers at the University of Arizona using images taken by the Voyager 2 spacecraft during its flyby of Neptune. Neso is one of Neptune's outer moons and is notable for its irregular, elongated shape, as well as its relatively large distance from Neptune, which is over 48,000 kilometers (about 30,000 miles).
The Pill Puzzle is a logical reasoning problem often presented as a brain teaser or puzzle. It typically involves a scenario where you have a certain number of pills, some of which are good (safe to take) and some of which are bad (harmful or lethal). The challenge often centers around identifying the good pills from the bad ones using a limited number of tests or a specific set of rules. Here's a common formulation of the Pill Puzzle: - You have a number of pills, say 12.
Béla Krekó is a Hungarian political scientist and expert in the fields of foreign policy, international relations, and political psychology. He is recognized for his work on topics related to Central and Eastern Europe, nationalism, and the impact of public opinion on foreign policy decisions. Krekó may also be involved in academic research, public discourse, and policy analysis.
In the context of mathematical optimization and differential geometry, the term "Hessian pair" generally refers to a specific combination of the Hessian matrix and a function that is being analyzed. The Hessian matrix, which represents the second-order partial derivatives of a scalar function, provides important information about the curvature of the function, and thus about the nature of its critical points (e.g., whether they are minima, maxima, or saddle points).
The Erasmus Smith's Professor of Mathematics is a prestigious academic position at Trinity College Dublin, the University of Dublin, Ireland. Established in 1752 through a bequest from Erasmus Smith, a wealthy merchant and philanthropist, the role is typically filled by a leading mathematician and involves both teaching and research responsibilities. The position is known for its contributions to mathematical sciences and its influence on mathematical education in Ireland.
Projective polyhedra are a class of geometric structures in the field of topology and geometry. More specifically, a projective polyhedron is a polyhedron that has been associated with the projective space, particularly projective 3-space. In topology, projective geometry can be understood as the study of geometric properties that are invariant under projective transformations.
John Ernst Worrell Keely (1827–1898) was an American inventor and self-proclaimed inventor of a revolutionary power generation system in the late 19th century. He is best known for his claims regarding a machine he developed, which he referred to as the "Keely motor." Keely claimed that his machine could harness a form of energy that he described as "vibrational force," and he asserted that it could produce perpetual motion.
Kauko Armas Nieminen was a Finnish fighter pilot during World War II, known for his significant contributions to the Finnish Air Force. He is often recognized for his combat achievements and skill in aerial warfare. Beyond his military service, he later became involved in aviation and played a role in the development of civil aviation in Finland. His legacy in Finnish aviation and military history remains notable.
The Coriolis effect refers to the apparent deflection of moving objects when they are viewed in a rotating reference frame, such as the Earth. This phenomenon is caused by the rotation of the Earth on its axis. In a rotating system, such as the Earth, objects moving over its surface appear to be deflected from their straight-line paths.
The Bloch sphere is a geometrical representation of the state space of a two-level quantum mechanical system, commonly referred to as a qubit. In quantum mechanics, qubits are the fundamental units of quantum information, analogous to classical bits, but they can exist in superpositions of 0 and 1 states. The Bloch sphere provides a visualization of the pure states of a qubit as points on the surface of a sphere.
Circular points at infinity are a concept from projective geometry, particularly relating to the projective plane and the study of lines and conics. In the context of projective geometry, the idea is to extend the usual Euclidean plane by adding "points at infinity," which allows us to treat parallel lines as if they meet at a point. In the case of conics, specifically circles, there are two points at infinity that are referred to as the "circular points at infinity.
Molecule mining is a term that typically refers to the process of identifying and extracting useful molecular compounds from a variety of sources, often with the goal of discovering new drugs or chemical substances. This process can involve several techniques and methodologies, depending on the context and the specific goals. Here are some key aspects: 1. **Natural Product Discovery**: Molecule mining can involve searching for bioactive compounds in natural sources like plants, fungi, and marine organisms.
In mathematics, particularly in the context of projective geometry, the concept of a hyperplane at infinity is an important idea used to facilitate the study of geometric properties. Here's a breakdown of the concept: 1. **Projective Space**: In projective geometry, we augment the usual Euclidean space by adding "points at infinity". This allows us to handle parallel lines and other geometric relationships more conveniently.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
