Socolar tiling refers to a type of mathematical tiling pattern that is based on a specific arrangement of tiles created by mathematician Joshua Socolar. These tilings are characterized by their ability to fill a plane with a repeating but non-periodic pattern. One well-known example of Socolar tiling is the "Socolar tiling of the plane," which can be constructed using a square tile that has a specific arrangement of colors or markings.
The term "solid sweep" can refer to different concepts depending on the context in which it is used. However, there are a couple of common interpretations: 1. **Sports Context**: In sports like baseball or basketball, a "solid sweep" typically refers to a team winning all games in a series or competition against another team (for example, winning all three or four games in a playoff series). A "solid sweep" would imply the victories were decisive and well-executed.
In mathematics, particularly in the field of algebraic geometry and topology, the term "projective cone" can refer to a construction involving projective spaces and cones in vector spaces.
A quaternionic polytope is a generalization of the concept of a polytope in the context of quaternionic geometry, much like how a polytope can be generalized from Euclidean spaces to spaces based on complex numbers. In basic terms, a polytope in Euclidean space is defined as a geometric object with flat sides, which can exist in any number of dimensions. A typical example is a polygon in 2D or a polyhedron in 3D.
Robust geometric computation refers to methods and techniques in computational geometry that aim to ensure the accuracy and reliability of geometric algorithms under various conditions. It addresses common issues such as numerical instability, precision errors, and degeneracies that can arise due to the finite representation of numbers in computer systems. Key aspects of robust geometric computation include: 1. **Exact Arithmetic**: Using arbitrary-precision arithmetic or symbolic computation to avoid errors associated with floating-point arithmetic.
SO(5) refers to the special orthogonal group in five dimensions. It is the group of all orthogonal 5x5 matrices with determinant 1.
As of my last update in October 2023, "Superegg" may refer to different things depending on the context. It could potentially relate to various sectors such as technology, gaming, education, or product branding. For example, in the tech industry, it might be a name for a startup, app, or innovative product. In gaming, it might represent a specific game, character, or feature.
The term "serpentine curve" can refer to a few different concepts, depending on the context. Here are the two most common: 1. **Mathematics**: In mathematics, a serpentine curve refers to a type of curve that resembles the shape of a serpent or snake, characterized by smooth, flowing bends. It can represent an infinite or a finite series of sine-like waves arranged in a serpentine or wavy pattern.
A simplicial manifold is a type of manifold that is constructed using the concepts of simplicial complexes. In topology, a simplicial complex is a set formed by joining points (vertices) into triangles (2-simplices), which are then joined into higher-dimensional simplices. A simplicial manifold has several key properties: 1. **Locally Euclidean**: Like all manifolds, a simplicial manifold is locally homeomorphic to Euclidean space.
Slewing can refer to different concepts depending on the context, but generally, it involves a gradual change or shift in position or orientation. Here are a few contexts in which the term is commonly used: 1. **In Astronomy**: Slewing refers to the movement of a telescope or an astronomical instrument as it adjusts its position to track celestial objects. This is particularly important in tracking moving objects like planets, comets, and satellites.
The small stellated 120-cell, also known as the stellated 120-cell or the small stellated hyperdiamond, is a specific type of honeycomb in four-dimensional space, classified among the convex regular 4-polytopes. It is a part of the family of 4-dimensional polytopes known as honeycombs, which are tessellations of four-dimensional space.
A toric section refers to a curve obtained by intersecting a torus (the surface shaped like a doughnut) with a plane. The intersection can produce different types of curves depending on how the plane intersects the torus. The possible outcomes include: 1. **Circle**: If the plane intersects the torus parallel to its axis of rotation. 2. **Ellipse**: If the plane intersects the torus at an angle but does not pass through the central hole of the torus.
A spherical sector is a three-dimensional geometric shape defined by a portion of a sphere. It is essentially the space enclosed by two radii of the sphere and a spherical cap. To understand it more intuitively, you can think of a spherical sector as being similar to a slice of a sphere, similar to how a wedge-shaped slice of an orange would be a sector of the orange.
A spherical segment is a three-dimensional shape that is formed by slicing a sphere with two parallel planes. The portion of the sphere that lies between these two planes is referred to as a spherical segment. In more specific terms, a spherical segment has the following characteristics: 1. **Base and Height**: The spherical segment can be defined by its height (the distance between the two parallel planes) and the radius of the sphere from which it is derived.
Tiling with rectangles is a mathematical and geometric concept that involves covering a given area or region completely with rectangles without overlaps or gaps. This is often referred to in the context of tiling a plane or a specific geometric shape (like a rectangle, square, or other polygons) using smaller rectangles. Here are a few key aspects of tiling with rectangles: 1. **Definition**: Tiling generally means that the area is subdivided into smaller pieces, which in this case are rectangles.
In mathematics, particularly in the context of geometry and topology, the term "truncus" generally refers to a truncated shape or solid, which is derived by cutting off a part of a geometric figure, typically one of its vertices. For instance, in three-dimensional geometry, truncating a polyhedron can involve cutting off its corners or edges, thereby transforming the original shape into a new solid with new faces.
Pinned article: ourbigbook/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.
