Ilya Prigogine (1917–2003) was a Belgian physical chemist and Nobel laureate best known for his work on Nonequilibrium Thermodynamics and complex systems. He made significant contributions to the understanding of thermodynamic processes far from equilibrium, introducing concepts such as dissipative structures, which are ordered structures that arise in systems that are not in equilibrium. Prigogine's work challenged traditional views of thermodynamics, which were primarily concerned with systems at equilibrium.
Thermodynamic databases for pure substances are comprehensive compilations of thermodynamic properties and data for individual chemical substances. These databases provide essential thermodynamic information that is critical for engineers, scientists, and researchers involved in various fields such as chemical engineering, materials science, thermodynamics, and environmental science. ### Key Features of Thermodynamic Databases: 1. **Properties Catalog**: - **Phase Behavior**: Information on phase changes, including phase diagrams, boiling points, melting points, and critical points.
Rotational temperature is a concept used in spectroscopy and thermodynamics to describe the temperature of a rotating molecule, specifically relating to its rotational energy levels. In quantum mechanics, molecules can rotate in space, and this rotation corresponds to quantized energy levels. These energy levels are influenced by the moment of inertia of the molecule and the rotational quantum numbers.
The Center for Analysis and Prediction of Storms (CAPS) is a research center based at the University of Oklahoma that focuses on improving the understanding and forecasting of severe weather phenomena, particularly thunderstorms, tornadoes, and other related storm systems. Established in 1996, CAPS integrates advanced observational techniques, numerical modeling, and data assimilation to enhance the accuracy and lead time of storm predictions.
A gustnado is a term used to describe a type of weather phenomenon associated with thunderstorms, specifically a shallow, rotating column of air that extends from the base of a thunderstorm. Unlike a tornado, which is a more organized and stronger rotating column of air that reaches from the clouds down to the ground, a gustnado typically forms at the outflow boundary of a storm, where cool air from a thunderstorm downdraft interacts with warm surface air.
"DYNO" can refer to different things depending on the context. Here are a few common interpretations: 1. **DYNO (Dyno)**: In automotive terms, a dynamometer (commonly called a "dyno") is a device used to measure force, torque, or power output of an engine. It's often used in performance tuning, racing, and automotive testing to assess how modifications affect a vehicle's performance.
The Icelandic Low is a significant atmospheric feature located over the North Atlantic Ocean, primarily associated with the area around Iceland. It is characterized by a region of low atmospheric pressure that influences weather patterns in northern Europe and North America. The Icelandic Low plays a crucial role in the general circulation of the atmosphere and is particularly prominent during the winter months when it can deepen and become more pronounced.
Tropical cyclones, also known as hurricanes or typhoons depending on their location, are characterized by low-pressure systems that produce strong winds, heavy rain, and can cause significant damage. The impact of tropical cyclones varies by country based on geographical location, preparedness, and resilience infrastructure. Here's a brief overview of how different countries experience tropical cyclones: ### 1.
A mesovortex is a term used in meteorology to describe a small-scale vortex within a larger weather system, such as a thunderstorm or a larger convective system. These vortices can occur at various scales, including those associated with individual storms or as part of larger circulation patterns. Mesovortices are typically characterized by their rotation and can lead to localized severe weather phenomena, including strong winds, tornadoes, or heavy rainfall.
The Borel Conjecture is a statement in set theory and the field of topology, specifically concerning the behavior of Borel sets in Polish spaces (complete, separable metric spaces). The conjecture asserts that every uncountable collection of Borel sets in a Polish space has a cardinality at most the continuum (the cardinality of the real numbers).
The Hauptvermutung, or "Main Conjecture," is a concept in topology, particularly in the field of algebraic topology. It refers to a conjecture about the nature of simplicial complexes and their triangulations. Specifically, the Hauptvermutung posits that if two simplicial complexes are homeomorphic (i.e., there is a continuous deformation between them without tearing or gluing), then they have the same number of simplices in each dimension.
The crossing number inequality is a concept from graph theory that relates to the crossing number of a graph, which is a measure of how many edges of the graph cross each other when the graph is drawn in the plane. The crossing number, denoted as \( cr(G) \), of a graph \( G \) is defined as the minimum number of crossings that occur in any drawing of the graph in the plane.
The left-right planarity test is a method used in graph drawing and computational geometry to determine whether a given graph can be drawn in a plane without edge crossings, specifically in a way that respects a certain left-right ordering of the vertices. In the context of embedded planar graphs, the left-right planarity test deals with directed graphs (digraphs) and attempts to find a planar embedding of the graph such that: 1. Each vertex is placed on a horizontal line.
The Wilson operation, also known as the Wilson loop, is a concept from quantum field theory, particularly in the context of gauge theories. It is named after Kenneth Wilson, who introduced it in the early 1970s as part of his work on lattice gauge theories and the study of confinement in quantum chromodynamics (QCD). In simple terms, the Wilson loop is a gauge-invariant quantity associated with the path of a loop in spacetime.
The Hirzebruch–Riemann–Roch theorem is a fundamental result in algebraic geometry and mathematical analysis that generalizes classical results from algebraic geometry and provides a powerful tool for computing topological invariants of complex manifolds. It connects the geometry of a manifold to its topology through characteristic classes.
Serre duality is a fundamental theoretical result in algebraic geometry and algebraic topology that relates cohomology groups of a projective variety, or a more general topological space, in a way that connects singular cohomology with dual spaces. Named after Jean-Pierre Serre, the duality provides a bridge between the geometry of a space and its cohomological properties.
Bott periodicity theorem is a central result in stable homotopy theory, named after the mathematician Raoul Bott. The theorem essentially states that the homotopy groups of certain topological spaces exhibit periodic behavior. More specifically, Bott periodicity is concerned with the stable homotopy groups of spheres and the stable homotopy classification of certain types of vector bundles.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
