The strange quark is one of the six types (flavors) of quarks in the Standard Model of particle physics. Quarks are fundamental particles that combine to form hadrons, such as protons and neutrons. ### Key Characteristics of the Strange Quark: 1. **Flavor**: The strange quark is distinguished by its flavor, which is one of the basic types of quarks, along with up, down, charm, top, and bottom quarks.
Baryon number is a quantum number in particle physics that represents the total number of baryons in a system. Baryons are a class of subatomic particles that include protons and neutrons, which are the building blocks of atomic nuclei. The baryon number is defined as follows: - Each baryon (like protons and neutrons) has a baryon number of +1.
"Bottomness" is not a widely recognized term in a specific academic or professional context, but it may refer to various concepts depending on the context in which it is used. Here are a few interpretations: 1. **Philosophical Context**: It could describe a state of being at the bottom of a hierarchical structure or system, emphasizing themes like despair, depression, or existential reflection.
Isospin, or isobaric spin, is a concept in particle physics that is used to describe the symmetry properties of particles, particularly those involved in strong interactions, such as protons and neutrons. It was introduced by the physicist Eugene Wigner in the 1930s as a way to categorize the nucleons (protons and neutrons) in a manner analogous to how spin describes intrinsic angular momentum.
Weak isospin is a quantum number associated with the weak interaction, one of the four fundamental forces of nature responsible for processes like beta decay in atomic nuclei. It is a key concept in the electroweak theory, which unifies the electromagnetic force and the weak nuclear force. In the context of particle physics, weak isospin is analogous to the concept of isospin (or isotopic spin) used for strong interactions, but it is specifically related to the weak force.
Jan Vaerman is a notable Belgian scientist known for his contributions to the fields of immunology and biotechnology. He is particularly recognized for his work on gene therapy and the development of vaccines. His research often focuses on the role of the immune system in disease and how it can be harnessed for therapeutic purposes.
Johannes Stadius, also known as Joannes Stadius, was a 16th-century Flemish astronomer and mathematician, known for his contributions to the field of astronomy during the Renaissance period. He is particularly noted for his work on celestial maps and his efforts to promote the Copernican heliocentric model of the universe. However, specific details about his life and contributions may be less well-documented compared to more famous figures of his time.
Michiel Coignet (also known as Michiel de Coignet) was a Flemish astronomer and mathematician who lived during the late 16th and early 17th centuries. He is best known for his work in developing and promoting scientific instruments, particularly for astronomy, and his contributions to cartography and geodesy.
Plateau–Rayleigh instability refers to a phenomenon that occurs when a fluid column or a liquid jet becomes unstable and breaks up into smaller droplets or fragments. This instability is named after the works of Joseph Plateau and Lord Rayleigh, who studied the behavior of liquids and the formation of droplets. The instability occurs under certain conditions, primarily due to surface tension forces acting on the fluid. When a liquid column is perturbed, surface tension works to minimize the surface area of the liquid.
Rayleigh–Bénard convection is a fluid dynamics phenomenon that occurs in a horizontal layer of fluid (such as a liquid or gas) that is heated from below and cooled from above. This setup creates a temperature gradient, where the bottom layer of fluid becomes warmer and less dense, while the top layer remains cooler and denser. As the bottom fluid heats up, it becomes buoyant and begins to rise, while the cooler, denser fluid descends to take its place.
Richard Courant (1888–1972) was a prominent mathematician known for his contributions to various fields, including mathematical analysis, partial differential equations, and mathematical physics. He was one of the founding figures of modern applied mathematics and played a key role in the establishment of mathematical education in the United States, especially through his work at New York University.
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems involving fluid flows. Computational fluid dynamicists are professionals or researchers who specialize in this field. Their work typically involves using mathematical models and computer-based simulations to study and predict the behavior of fluids (liquids and gases) under various conditions.
Adhémar Jean Claude Barré de Saint-Venant (1797-1886) was a French engineer and mathematician known for his significant contributions to the fields of mechanics and fluid dynamics, particularly in the study of elasticity and the flow of fluids. He is best known for formulating the Saint-Venant's principle, which is a fundamental concept in structural engineering and elasticity theory.
Adolf Busemann (1901–1986) was a prominent German-American aerospace engineer and physicist known for his contributions to the fields of aerodynamics and compressible flow. He is particularly noted for his work on the Busemann biplane, a design that aimed to reduce drag and enhance the performance of aircraft.
Adrian Bejan is a Romanian-American engineer and professor known for his contributions to the field of thermal and fluid sciences. He is particularly recognized for his work on the constructal theory, which he developed in the 1990s. Constructal theory describes how flow structures in nature, like rivers and trees, evolve to facilitate the movement of energy and matter. Bejan's research spans various areas, including thermodynamics, heat transfer, and sustainable design.
Adrian Gill is a meteorologist known for his contributions in the field of weather forecasting and climate research. He has been involved in various aspects of meteorology, including the development of weather prediction models and the study of climate phenomena.

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.
