In mathematics, the term "substructure" generally refers to a subset or a smaller structure that satisfies certain properties of a larger mathematical structure. This concept appears in various areas of mathematics, including algebra, set theory, and model theory. Here are a few contexts in which "substructure" is commonly discussed: 1. **Algebra:** In algebraic structures such as groups, rings, and fields, a substructure is typically a subset that itself forms a similar structure.

The Sumerian creation myth is a collection of stories that describe the origins of the universe, the gods, and humankind according to the ancient Sumerians, one of the earliest known civilizations located in present-day southern Iraq. One of the most notable texts that recounts the Sumerian creation myth is the "Eridu Genesis," which provides insight into the beliefs and cosmology of the Sumerian people.
A **superabundant number** is a positive integer \( n \) for which the ratio of the sum of its divisors \( \sigma(n) \) to \( n \) is greater than the ratio for any smaller positive integer \( m \).
Supermathematics is an area of mathematical study that extends traditional mathematical concepts to include the treatment of "super" or "graded" structures, often arising in the context of supersymmetry in physics. It typically involves the introduction of entities called "supernumbers," which include both ordinary numbers and elements that behave like variables but have a degree of "oddness" or "evenness." In more technical terms, supermathematics is associated with superalgebras and supermanifolds.
The Wiedemann–Franz law is a principle in solid-state physics and materials science that relates the electrical conductivity of a metal to its thermal conductivity. It states that the ratio of the thermal conductivity (\(K\)) to the electrical conductivity (\(\sigma\)) of a metal is proportional to the temperature (\(T\)).
Firearms can be categorized by their action type, which refers to the mechanism by which a firearm loads, fires, and ejects cartridges. Here are some common types of firearm actions: 1. **Bolt Action**: In bolt-action firearms, a manually operated bolt is used to load each cartridge from a magazine into the chamber. The shooter must pull the bolt back, which ejects the spent cartridge, and then push it forward to load a new round.
Surround optical-fiber immunoassays are a type of biosensing technology that combines optical fiber principles with immunoassay techniques to detect and quantify specific biological molecules, typically antigens or antibodies. This method leverages the inherent qualities of optical fibers, such as their ability to transmit light and detect changes in light properties, to improve sensitivity, specificity, and speed of immunoassay results.
Firearm maintenance refers to the regular care and servicing of firearms to ensure they operate safely and effectively. Proper maintenance is critical for the performance, longevity, and reliability of the firearm. Here are the key aspects of firearm maintenance: 1. **Cleaning**: Regular cleaning is essential to remove dirt, debris, and residues from gunpowder and other substances that can accumulate during use. This typically involves disassembling the firearm, cleaning the barrel and action, and lubricating moving parts.
Sylvester's criterion is a mathematical principle used to determine whether a given real symmetric matrix is positive definite. According to Sylvester's criterion, a real symmetric matrix \( A \) is positive definite if and only if all of its leading principal minors (the determinants of the top-left \( k \times k \) submatrices for \( k = 1, 2, \ldots, n \), where \( n \) is the order of the matrix) are positive.

Tarvos is a moon of the planet Saturn. It is one of the smaller, irregularly shaped moons that belong to the larger group known as the Inuit group, which are characterized by their similar orbits and physical characteristics. Tarvos was discovered in 2000 and is named after a figure in Celtic mythology, specifically a giant associated with the bull. The moon has an average diameter of about 13 kilometers (approximately 8 miles), making it one of the smaller moons of Saturn.

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.
