"Pretzel link" may refer to a few different concepts depending on the context. Here are a couple of possibilities: 1. **Pretzel (Snack)**: In the most common context, a pretzel is a baked bread product, usually shaped into a knot or loop, and often sprinkled with coarse salt. A "link" in this context might refer to a recipe link or a product link associated with pretzels.
A cuboctahedral pyramid is a geometric structure that can be visualized as a pyramid whose base is a cuboctahedron. To break this down further: 1. **Cuboctahedron**: This is a convex polyhedron with 8 triangular faces and 6 square faces, and it has 12 edges and 12 vertices. It can be thought of as the intersection of a cube and an octahedron.
The great duoantiprism is a type of convex polyhedron that is part of the category of Archimedean solids. It is characterized by its unique structure, which consists of two layers of triangular faces. The solid can be viewed as a combination of a duoantiprism and an additional layer of triangular faces that create an intricate arrangement.
The geometry and topology of three-manifolds is a rich and complex area of mathematics that deals with understanding the properties and structures of three-dimensional spaces (or manifolds). Here are the key concepts and themes involved: ### Manifolds A **manifold** is a topological space that locally resembles Euclidean space. An **n-manifold** is a space that is locally similar to \( \mathbb{R}^n \).
The Weeks manifold is a specific example of a closed 3-manifold that is often studied in the field of topology and geometric topology. It is particularly noted for its properties in relation to hyperbolic geometry. ### Key Features of the Weeks Manifold: 1. **Closed 3-Manifold**: The Weeks manifold is compact, has no boundary, and can be considered a type of three-dimensional shape.
As of my last knowledge update in October 2023, "Sudines" does not refer to a specific, widely recognized term or concept in popular culture, science, or other fields. It might be a misspelling or a lesser-known term. Could you provide more context or clarify what you mean by "Sudines"? It could be related to a brand, a character, or something else entirely.
Iamblichus was a Neoplatonist philosopher who lived in the 3rd to 4th century CE, known for his significant contributions to the development of Neoplatonism. He was born in Chalcis, in what is now modern-day Syria, and was a student of Porphyry, who was a predecessor in the Neoplatonic tradition.
A "capped grope" typically refers to a specific type of information structure or organization used in data management, particularly in the context of databases or data structures in computer science. However, the term "capped grope" itself is not widely recognized or standard terminology within established fields like computer science, data management, or mathematics.
The Triakis truncated tetrahedral honeycomb is a type of honeycomb structure in three-dimensional space formed by a specific arrangement of truncated tetrahedra and triangular prisms. In more detail: - A **honeycomb** refers to a repetitive, tessellated arrangement in which space is filled with a defined geometric shape without any gaps.
Severus Sebokht, also known as Severus of Ashmoune, was a prominent 7th-century Christian theologian and scholar from the region of the Middle East, particularly associated with the Syriac Orthodox Church. He is noted for his contributions to Syriac literature and thought, and he played a significant role in the theological discussions of his time.
Exotic \(\mathbb{R}^4\) refers to a concept in differential topology, specifically in the study of manifolds and their structures. In standard mathematics, \(\mathbb{R}^4\) can be understood as the four-dimensional Euclidean space, which is a familiar and straightforward geometric concept.
Seiberg-Witten invariants are topological invariants associated with four-dimensional manifolds, particularly those that admit a Riemannian metric of positive scalar curvature. They arise from the work of N. Seiberg and E. Witten in the context of supersymmetric gauge theory and have significant implications in both mathematics and theoretical physics.
Taubes's Gromov invariant is a concept from symplectic geometry and gauge theory, particularly associated with the study of pseudo-holomorphic curves and their index theory. The invariant is named after mathematician Claude Taubes, who introduced it in his work on the relationships between symplectic manifolds and four-manifolds.
A dodecahedral pyramid is a three-dimensional geometric figure that consists of a regular dodecahedron (a polyhedron with twelve flat faces that are regular pentagons) as its base, with triangular faces rising to a single apex point above the base. To understand the structure of a dodecahedral pyramid: 1. **Base**: The base is a regular dodecahedron, which has 12 pentagonal faces, 20 vertices, and 30 edges.
The Grand 120-cell is a four-dimensional convex polytope, which is one of the higher-dimensional analogs of three-dimensional shapes. It is part of a class of polytopes known as "regular polytopes" in four dimensions, specifically a type of "uniform 4-polytope". The Grand 120-cell is an extension of the 120-cell, one of the six regular convex 4-polytopes.
A truncated icosahedral prism is a three-dimensional geometric shape that extends a truncated icosahedron along a perpendicular axis, forming a prism. To understand this shape, we need to break it down into its components: 1. **Truncated Icosahedron**: This is a well-known Archimedean solid that consists of 12 regular pentagonal faces and 20 regular hexagonal faces.
A truncated octahedral prism refers to a geometric figure that combines elements of a truncated octahedron and a prism structure. 1. **Truncated Octahedron**: A truncated octahedron is a type of Archimedean solid that has 8 regular hexagonal faces and 6 square faces. It is created by truncating (or cutting off) the corners of a regular octahedron.
A polytetrahedron generally refers to a geometric figure that is a higher-dimensional analogue of a tetrahedron. 1. **Tetrahedron in 3D**: A tetrahedron is a three-dimensional shape (a polyhedron) with four triangular faces, six edges, and four vertices. 2. **Generalization to Higher Dimensions**: In higher dimensions, a polytetrahedron can be thought of as the simplest form of a polytope in that dimension.
Anthemius of Tralles was a prominent Byzantine architect and engineer who lived during the 6th century AD. He is best known for his work on the Hagia Sophia in Constantinople (now Istanbul), which is considered one of the greatest architectural achievements in history. Anthemius, alongside his colleague Isidore of Miletus, was responsible for the innovative design of the building, particularly its large dome and complex structural system.
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.
