Orthographic projection is a method of representing three-dimensional objects in two dimensions. It utilizes parallel lines to project the features of an object onto a plane, resulting in a series of views that are accurate in scale but do not show perspective. This technique is commonly used in technical drawing, engineering, and computer graphics to create representations of objects that allow for clear communication of dimensions and details without the distortion associated with perspective drawing.
Projectivization is a concept that arises in various fields of mathematics, particularly in geometry and algebraic geometry. Roughly speaking, it refers to the process of taking an object defined in a certain geometric or algebraic space and constructing a new object that represents it in a projective space.
A radial set typically refers to a collection of points that are defined based on their distance from a central point, often organized in a way that resembles a circle or sphere in geometric contexts. The term can be used in various fields, including mathematics, physics, and computer science, often to describe distributions or arrangements of data or elements radiating outward from a central origin.
In mathematics, the term "tapering" is not a standard term with a universally accepted definition. However, it may refer to a few different concepts depending on the context in which it is used: 1. **Tapering in Functions:** Tapering can describe the behavior of functions that gradually decrease (or increase) in magnitude towards a certain point. For example, a function might taper off to zero as it approaches a certain limit.
Vectorization in mathematics, particularly in the context of linear algebra and computational mathematics, refers to the process of converting an operation that is typically performed on scalars or a collection of operations on individual elements into an operation that can be applied to vectors or matrices in a more efficient and compact form. This technique is often used to enhance performance in numerical computations, particularly in programming environments that support vectorized operations, such as NumPy in Python or MATLAB.
Pascal's rule, also known as Pascal's triangle property, refers to a specific combinatorial identity related to binomial coefficients.
The Weitzenböck identity is a mathematical identity in the context of Riemannian geometry, particularly involving the Laplace-Beltrami operator. Named after the mathematician Roland Weitzenböck, it relates the curvature of a Riemannian manifold to certain differential operators. In general terms, the Weitzenböck identity can express a relationship involving the Laplacian of a differential form and the curvature of the manifold.
Morrie's Law, often attributed to Morrie Schwartz, a sociology professor who became widely known through the book "Tuesdays with Morrie" by Mitch Albom, suggests that the more one embraces suffering and life’s challenges, the more wisdom, strength, and insight one can gain. The essence of Morrie's teachings emphasizes the importance of human connection, the inevitability of death, and the pursuit of meaningful relationships.
The Bernstein polynomial is a crucial concept in approximation theory and mathematical analysis, particularly in the context of polynomial interpolation and approximation of continuous functions. The Bernstein polynomials are defined to approximate a continuous function on a closed interval [0, 1] by a weighted sum of polynomials.
A squared triangular number is a special type of number that is both a triangular number and a perfect square. A triangular number is a number that can form an equilateral triangle. The \( n \)-th triangular number is given by the formula: \[ T_n = \frac{n(n + 1)}{2} \] A perfect square is an integer that is the square of an integer.
The Mahler measure is a concept from number theory and algebraic geometry that provides a way to measure the "size" or "complexity" of a polynomial or a rational function.
Monomial order is a method used to arrange or order monomials (single-term polynomials) based on specific criteria. In the context of polynomial algebra and computational algebra, the order of monomials plays an important role, particularly in polynomial division, Gröbner bases, and algebraic geometry.
Giambelli's formula is a mathematical formulation used to compute the roots of a polynomial, specifically for polynomial equations of degree \( n \) expressed in the form: \[ P(x) = a_n x^n + a_{n-1} x^{n-1} + \ldots + a_1 x + a_0 \] The formula provides a way to express the roots of the polynomial in terms of its coefficients and is particularly useful in the context of the theory
The Von Neumann paradox, also known as the "Von Neumann architecture paradox," is a concept in the field of game theory and economics, particularly in the context of decision-making and self-referential systems. However, there is another related concept often referred to as the "paradox of choice" in decision-making processes.
Kostka polynomials are combinatorial objects that arise in the representation theory of the symmetric group and in the study of symmetric functions. They serve as a bridge between different bases of the ring of symmetric functions, particularly the Schur functions and the monomial symmetric functions.
Plethystic substitution is a concept from the field of algebra, specifically in the context of symmetric functions and combinatorial algebra. It is a generalization of the classical notion of substitution in polynomials and symmetric functions. In mathematical terms, plethystic substitution allows one to substitute a polynomial or power sum of variables into a symmetric function, typically a generating function. The key idea is to transform one kind of function into another while preserving certain structural properties.
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.
