An epicycloid is a type of curve generated by tracing the path of a point on the circumference of a smaller circle (called the generating circle) as it rolls around the outside of a larger stationary circle (called the base circle). The resulting shape is a closed curve if the smaller circle rotates an integer number of times around the larger circle.
The second fundamental form is a mathematical object used in differential geometry that provides a way to describe how a surface bends in a higher-dimensional space. Specifically, it is associated with a surface \( S \) embedded in a higher-dimensional Euclidean space, such as \(\mathbb{R}^3\).
In ring theory, which is a branch of abstract algebra, a **V-ring** (or **valuation ring**) is a specific type of integral domain that has certain properties related to valuations. A valuation is a function that assigns values to elements in a field which helps in determining the "size" or "order" of those elements.
The homogeneous coordinate ring is a mathematical construct used primarily in algebraic geometry and projective geometry. It provides a way to systematically handle projective space and the geometric objects that reside within it, such as points, lines, and higher-dimensional varieties. ### Definition Consider projective space \(\mathbb{P}^n\) over a field \(k\).
Routing algorithms are protocols and procedures used in networking to determine the best path for data packets to travel across a network from a source to a destination. These algorithms are critical in both computer networks (including the internet) and in telecommunications, ensuring efficient data transmission. ### Types of Routing Algorithms: 1. **Static Routing:** - Routes are manually configured and do not change unless manually updated. Best for small networks where paths are predictable.
An algorithm is a finite sequence of well-defined instructions or steps designed to perform a specific task or solve a particular problem. Algorithms can be expressed in various forms, including natural language, pseudocode, flowcharts, or programming code. Key characteristics of algorithms include: 1. **Clear and Unambiguous**: Each step must be precisely defined so that there is no uncertainty about what is to be done.
The Algorithm Auction is a concept in the field of algorithmic trading and financial markets, though specific references could vary based on context. Generally, this could refer to auctions or bidding processes where algorithms are used to determine prices, match buyers and sellers, or facilitate transactions in a financial marketplace. In more specialized contexts, The Algorithm Auction might refer to: 1. **Auction Mechanisms**: Platforms where algorithms can bid on assets, shares, or other financial instruments in real-time.
Cary Forest is a forested area located in the northeastern part of the United States, specifically in the state of New Jersey. It is part of the larger Pinelands National Reserve, known for its unique ecology, diverse plant and animal life, and sandy soils. The forest provides recreational opportunities such as hiking, birdwatching, and nature study, while also offering habitats for various species.

His work often involves precision measurements and innovative experimental techniques.
Mareena Robinson Snowden is an American nuclear engineer and a prominent advocate for diversity and inclusion in the field of engineering and science. She is known for her work in the nuclear energy sector, where she focuses on advancing technologies that promote safe and sustainable nuclear power. Additionally, she has been involved in educational outreach and initiatives aimed at inspiring underrepresented groups to pursue careers in STEM (science, technology, engineering, and mathematics).
Nitin Samarth is not a widely recognized public figure or concept, and it may refer to a specific individual or a niche term within a certain context.
John Kekes is a philosopher known for his work in various areas of philosophy, including ethics, epistemology, and the philosophy of action. He has contributed significantly to discussions on the nature of values, moral philosophy, and the implications of philosophical thought for everyday life. He is particularly noted for his ideas on how philosophical inquiry can help individuals lead a good life. Kekes has authored several books and articles that explore these themes, and he often emphasizes the importance of a practical approach to philosophy.
Michael P. Brenner is a prominent American physicist and professor known for his work in applied physics and engineering. He is a member of the faculty at Harvard University, where he has contributed significantly to various fields, including fluid dynamics, soft matter physics, and materials science. Brenner’s research often involves theoretical and experimental approaches to understand complex systems and phenomena. In addition to his academic contributions, he has published numerous papers and has been involved in interdisciplinary research that spans multiple scientific domains.
Nandi Olive Leslie is a plant species known for its ornamental value and potential medicinal properties. It belongs to the genus Nandi, which includes various species of plants. The specifics about Nandi Olive Leslie, including its uses, characteristics, and habitat, might not be widely documented or may vary depending on the regional context. For detailed information, additional context, or updates regarding its classification and uses, it’s recommended to consult botanical references or databases.
Constraint inference refers to the process of deducing or deriving new constraints from existing constraints within a logical framework, mathematical model, or computational system. This concept is prevalent in various fields, including artificial intelligence, operations research, optimization, and formal verification.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
