Kelvin's circulation theorem is a fundamental principle in fluid dynamics, particularly in the study of inviscid (non-viscous) and irrotational flows. It states that the circulation around a closed contour moving with the fluid is constant in time, provided the flow is conservative and the fluid is incompressible and inviscid.
The Korteweg–de Vries (KdV) equation is a third-order nonlinear partial differential equation that describes the evolution of waves in shallow water. It is significant in various fields, including fluid dynamics, nonlinear wave theory, and mathematical physics.

One notable Frederick Kaufman is a writer and journalist known for his work on topics related to food, agriculture, and economics. He has contributed articles to various publications and has authored books, including "Bet the Farm: How Food Stopped Being Food," which examines the complexities of the modern food system and the implications of industrial agriculture.
Physical chemists, like scientists in any other field, come from diverse national backgrounds. The field of physical chemistry is practiced worldwide, and researchers and professionals can be found in countries across all continents. Some key nations known for their contributions to physical chemistry include: 1. **United States** - Home to many leading universities and research institutions. 2. **Germany** - Known for its strong emphasis on chemical research and education. 3. **United Kingdom** - Hosts many renowned chemists and research organizations.
Theoretical chemists are scientists who use mathematical models, computational techniques, and abstract theories to understand and predict chemical phenomena. This field of chemistry emphasizes the development and application of theoretical methods to study the properties and behaviors of molecules, atoms, and chemical systems. Theoretical chemists often work in conjunction with experimental chemists, using their models to interpret experimental data, design new experiments, or even predict new compounds and reactions.
Albert Fredrick Ottomar Germann does not appear to correspond to a widely recognized figure, event, or concept in historical, scientific, or popular context based on the information available up to October 2023. It could be a name of a private individual or a lesser-known person, possibly related to a specific niche or local context.
Stokes flow refers to the flow of an incompressible viscous fluid at low Reynolds numbers, where inertial forces can be neglected in comparison to viscous forces. This type of flow is governed by the Stokes equations, which are simplified forms of the Navier-Stokes equations. These equations assume that the fluid is Newtonian, meaning its viscosity is constant and the stress is linearly proportional to the rate of strain.
Washburn's equation describes the capillary action of liquids in porous media or thin tubes. It quantifies the rate at which a liquid will diffuse into a porous material due to capillary forces. The equation is often used in the context of materials science, fluid mechanics, and petroleum engineering, among other fields.
Axiom A is a concept in dynamical systems introduced by mathematician Stephen Smale in the 1960s. It describes a class of systems that have certain hyperbolic properties, which means they exhibit chaotic behavior yet retain a structured dynamic. More specifically, Axiom A refers to a dynamical system where: 1. The system's phase space can be decomposed into an unstable manifold and stable manifold, making it possible to analyze orbits and their behavior under iteration.
Hendrik van Heuraet is a name that may refer to various topics, but it is most commonly associated with Hendrik van Heuraet (or Heuraet), a Dutch painter from the 17th century, known for his genre paintings and portraits.
René Goormaghtigh (1865-1953) was a Belgian mathematician known for his work in the fields of mathematics, particularly in geometry and analysis. He made significant contributions to various areas in mathematics and was involved in the promotion of mathematical education.

Nazım Terzioglu is not widely recognized in mainstream media or academia as of my last knowledge update in October 2023. It’s possible that he could be a private individual, a local figure, or someone who has gained prominence in specific fields after that date. If you could provide more context or specify which area you are referring to (like literature, art, science, etc.
A Gas Electron Multiplier (GEM) is a type of gas detector used in particle physics and radiation detection. It is designed to amplify the ionization created by charged particles interacting with a gas medium. Here's how it works and its key features: ### Structure and Function 1. **Design**: A GEM consists of a thin plastic or metallic foil with holes (microholes) that are typically a few tens of micrometers in diameter.
Stirling numbers of the first kind, denoted by \(c(n, k)\), count the number of ways to express a permutation of \(n\) elements as a product of \(k\) disjoint cycles. In other words, they are used in combinatorial mathematics to determine how many different ways a set can be partitioned into cycles.
