The triple point of a substance is the specific temperature and pressure at which the three phases of that substance—solid, liquid, and gas—can coexist in thermodynamic equilibrium. At this unique point, the solid, liquid, and vapor phases of the substance are in balance, meaning that any change in one phase can lead to the formation or conversion into another phase without altering the overall pressure and temperature.
Alice T. Schafer was a notable American mathematician recognized for her contributions to mathematics and mathematics education. She was one of the few women to earn a Ph.D. in mathematics during her time, receiving her degree from Radcliffe College in 1940. Schafer was an advocate for increasing the participation of women in mathematics and played a significant role in mathematics education.
In thermodynamics, "work" is a defined form of energy transfer that occurs when a force is applied to an object, causing that object to move. Work is a fundamental concept and is closely associated with energy changes in a system. In the context of thermodynamics, work is usually denoted by \( W \) and can be expressed mathematically.
A working fluid is a substance used in thermodynamic cycles to transfer energy, typically in the form of heat, work, or both. It is the medium through which energy is exchanged in various thermal processes, such as heat engines, refrigeration cycles, and heat pumps. Key characteristics of working fluids include: 1. **Phase Change**: Many working fluids undergo phase changes (e.g.
The Alexandroff plank, named after the Russian mathematician Pavel Alexandroff, is a specific topological space that serves as an example in topology, particularly in the study of compactness and connectedness. It is constructed by taking the product of a closed interval with a certain type of topological space.
Hawaiian earrings typically refer to earrings that are inspired by the traditional art and culture of Hawaii. These earrings often feature motifs and designs that are associated with Hawaiian imagery, such as flowers (like hibiscus), sea life, and other natural elements that reflect the beauty of the islands. Materials used in Hawaiian earrings can vary widely, including precious metals, shells, wood, and coral.
In the context of mathematics, particularly functional analysis and linear algebra, the term "Ran space" typically refers to the range of a linear operator or a linear transformation. The range (or image) of a linear operator \( T: V \to W \), where \( V \) and \( W \) are vector spaces, is the set of all vectors in \( W \) that can be expressed as \( T(v) \) for some \( v \) in \( V \).
Rational sequence topology is a type of topology that can be defined on the set of rational numbers, and it provides a way to study properties of rational numbers using a topological framework. This topology is notably used in mathematical analysis and can be insightful for understanding convergence, continuity, and compactness in contexts where the standard topology on the rationals (induced by the Euclidean topology on the real numbers) may not be ideal.
The Sierpiński carpet is a well-known fractal and two-dimensional geometric figure that exhibits self-similarity. It is constructed by starting with a solid square and recursively removing smaller squares from it according to a specific pattern. Here’s how it is typically created: 1. **Start with a Square**: Begin with a large square, which is often considered a unit square (1 x 1).
The Sorgenfrey plane is a topological space that is constructed from the real numbers, specifically using the Sorgenfrey line as its foundational element. The Sorgenfrey line is obtained by equipping the set of real numbers \(\mathbb{R}\) with a topology generated by half-open intervals of the form \([a, b)\), where \(a < b\). This creates a topology that is finer than the standard topology on \(\mathbb{R}\).
Aleksei Chernavskii might refer to a specific individual, but as of my last knowledge update in October 2023, there isn't widely recognized information or notable references to a person by that name in public sources.
Daniel Biss is an American mathematician and politician. He is known for his work in the field of mathematics, particularly in the areas of algebraic geometry and combinatorics. Biss earned a Ph.D. in mathematics from the University of California, Berkeley, and has held academic positions at institutions such as Northwestern University. In addition to his academic career, Biss has also been active in politics.
David B. A. Epstein is an American attorney and author known for his work in the field of intellectual property, particularly in patent law. He has written extensively on topics related to law and technology, including issues surrounding modern legal practice, litigation, and the impact of technology on intellectual property rights. If you have a specific area of interest regarding David B. A.
Path-constrained rendezvous is a concept in computer science and robotics, often discussed in the context of multi-agent systems or robotic coordination. It refers to the problem of coordinating multiple agents (or robots) to meet at a specific location (the rendezvous point) while adhering to specified constraints on their paths. These constraints can include limits on the distance each agent can travel, time constraints, or other limitations related to the operational environment.
Arthur Harold Stone is best known for his contribution to mathematics, particularly in the fields of topology and set theory. He is recognized for his work on the concept of "Stone spaces," which are named after him. These spaces play an important role in various areas of mathematics, including functional analysis and algebra.
Daina Taimiņa is a Latvian-American mathematician known for her work in topology and geometry, particularly in the study of knot theory and mathematical visualization. She is a professor at the Department of Mathematics at the University of Maine and is recognized for her contributions to the understanding of knots and surfaces through the use of computer graphics. One of her notable accomplishments is her exploration of the relationship between topology and visual representation, including her work with hyperbolic geometry and its connection to art.

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.
