Pseudo-modal energies are a concept utilized in various fields, including physics, material science, and structural analysis, to describe certain characteristics of systems that can be analyzed through modal analysis techniques. While the term "pseudo-modal" may not be uniformly defined across disciplines, it generally refers to energies associated with the modes of vibration or deformation in a system that are not necessarily "true" modes in the traditional sense.
Cellular dewetting is a process that occurs when a thin film or coating of a liquid, typically a polymer or surfactant, begins to break up into discrete droplets or clusters due to instabilities that arise at the film's surface. This phenomenon can be observed in various systems, including thin polymer films and lipid bilayers.
In group theory, which is a branch of abstract algebra, the concepts of centralizer and normalizer help us understand the structure of groups and their subgroups. Here are the definitions of both: ### Centralizer The centralizer of a subset \( S \) of a group \( G \), denoted as \( C_G(S) \), is the set of all elements in \( G \) that commute with every element of \( S \).
The term "certifying algorithm" typically refers to a type of algorithm that not only provides a solution to a computational problem but also generates a verifiable certificate that can confirm the correctness of the solution. This can be particularly important in fields like theoretical computer science, optimization, and cryptography, where validating solutions efficiently is crucial. ### Key Features of Certifying Algorithms: 1. **Correctness Proof**: The algorithm not only computes a result (e.g.
"Ceyuan Haijing" (also known as "The Sea Mirror of the Complete Source") is a famous Chinese maritime literary work, often attributed to the Ming dynasty. It was written by the scholar and navigator Xu Xiake. The work is a comprehensive account of China's maritime activities, including navigation techniques, sea routes, and descriptions of various islands and coastal areas.
George Szekeres (born on February 24, 1916 – died on June 8, 2005) was a notable mathematician known for his contributions to various fields, particularly in combinatorics and number theory. He is perhaps best known for his work in the area of discrete mathematics, including his contributions to the theory of algorithms and complexity.
Chinese mathematical discoveries have a rich history that spans thousands of years, contributing significantly to mathematics as we know it today. Here are some key aspects and discoveries in Chinese mathematics: 1. **Ancient Mathematical Texts**: - **The Nine Chapters on the Mathematical Art (Jiuzhang Suanshu)**: This classic text, compiled around the 1st century AD, covers various topics such as arithmetic, geometry, and linear equations.
Bowen's Kale, also known as "Bowen's kale" or by its scientific name *Brassica oleracea var. sabellica*, is a type of ornamental kale that is often grown for its aesthetic appeal rather than its culinary use. It is a member of the Brassica family, which includes many common vegetables such as cabbage, broccoli, and Brussels sprouts.
A Pronic number, also known as a rectangular or oblong number, is a number that can be expressed as the product of two consecutive integers. In mathematical terms, a Pronic number can be represented as \( n(n + 1) \), where \( n \) is a non-negative integer.
The Bow-wow theory is one of several theories of language origin that attempts to explain how human language might have developed. Specifically, it suggests that language originated from the sounds that early humans made in response to the external world, particularly imitative sounds—essentially, humans mimicking the sounds of animals or natural phenomena. This theory posits that certain words in early language arose from the natural noises associated with the objects or actions they represent.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
