As of my last knowledge update in October 2023, there is no widely recognized entity or concept specifically known as "Femisphere." It's possible that it could refer to a brand, a product, an organization, or a concept that emerged after that date, or it may be a colloquial term or niche concept that wasn't widely documented.
Organicism is a philosophical and theoretical perspective that emphasizes the idea that systems, whether they are biological, social, or artistic, are best understood as wholes rather than simply as the sum of their parts. This approach draws analogies between living organisms and various systems, positing that these systems exhibit structural and functional relationships similar to those found in nature.
Kinetic art is a genre of art that incorporates movement as a fundamental aspect of its expression. This movement can be induced by a variety of mechanisms, such as motors, wind, water, or the action of viewers interacting with the artwork. Kinetic art can take many forms, including sculptures, installations, and works on paper.
Ferdinand Minding does not appear to have significant recognition or established relevance in widely known fields, such as history, literature, science, or popular culture, based on the information available up to October 2023. It's possible that he could be a lesser-known figure, or the name might be relevant in a specific niche context.
Paul Émile Appell was a French mathematician known for his contributions to various areas of mathematics, particularly in geometry and analysis. Born on 8 February 1855 and passing away on 7 January 1931, he is perhaps best known for his work in projective geometry and for his involvement in the development of mathematical education in France. In addition to his research contributions, Appell was also recognized for his role as an educator and in the promotion of mathematics as a discipline.
The Reuleaux tetrahedron is a three-dimensional geometric shape that is a type of convex hull formed around a tetrahedron. A Reuleaux tetrahedron is created by taking the convex hull of four points that are the vertices of a regular tetrahedron and then forming a shape by connecting arcs of circles centered at these vertices.
Gerard of Brussels, also known as Gerardus Brabantius, was a Flemish painter from the late 15th to early 16th century. He is often associated with the Northern Renaissance and is recognized for his contributions to the art of the period in the region of present-day Belgium. Although specific details about his life are scarce, his works typically feature themes common to the time, such as religious subjects, landscapes, and portraits.
The Minkowski–Hlawka theorem is a result in number theory and the geometry of numbers that pertains to the representation of integer points in geometric space. Specifically, it addresses the existence of points with integer coordinates within certain convex bodies in Euclidean space.
An oloid is a three-dimensional geometric shape formed by the combination of two circular disks of equal radius, which are joined at their edges. The shape has a distinctive smooth, continuous surface and unique mathematical properties. When one of the disks rolls on a flat surface, the oloid can create a fascinating motion because of its unique curvature. The oloid was first described by the mathematician Paul Schatz in the 1920s.
The Superformula is a mathematical formula introduced by Johan Gielis in 2003. It generalizes the notion of shapes and can describe a wide variety of geometrical forms, including regular polygons, stars, and more complex figures. The formula is defined in polar coordinates and is particularly noted for its versatility and ability to create smooth, continuous shapes.
The term "tri-oval" commonly refers to a specific type of racetrack design that features a shape resembling a three-oval configuration. The most famous example of a tri-oval is the NASCAR racetrack, which has its roots in oval racing but incorporates a unique design that allows for a better racing experience. A tri-oval track typically has three distinct corners and straights that create a flow intended to enhance speed and promote competitive racing.
Symmetrization methods refer to a class of mathematical techniques used in various fields such as analysis, probability, and geometry to simplify problems by exploiting symmetries. These methods often transform a given object into a more symmetric one, making it easier to study properties, derive estimates, or provide proofs. ### Key Concepts of Symmetrization Methods: 1. **Symmetrization in Mathematics**: This generally involves replacing a non-symmetric object (like a function or a shape) with a symmetric one.
Curvilinear motion refers to the motion of an object along a curved path. Unlike linear motion, which occurs in a straight line, curvilinear motion involves changing directions while the object moves, resulting in a trajectory that is not straight. Some key characteristics of curvilinear motion include: 1. **Trajectory**: The path taken by the object is curved, which can be circular, elliptical, or any other non-linear shape.
The laws of motion, formulated by Sir Isaac Newton in the 17th century, are three fundamental principles that describe the relationship between the motion of an object and the forces acting upon it. These laws are foundational to classical mechanics and provide a framework for understanding how objects move.
A D-interval hypergraph is a specific type of hypergraph that arises in combinatorial mathematics and graph theory. In general, a hypergraph is a generalized graph where edges, called hyperedges, can connect any number of vertices, not just two as in standard graphs. In the context of D-interval hypergraphs, the "D" typically refers to a specific structure or constraint regarding the intervals associated with the hyperedges.
The strong product of two graphs \( G \) and \( H \), denoted as \( G \boxtimes H \), is a graph that combines the structures of both \( G \) and \( H \) in a way that incorporates features from both the Cartesian product and the tensor product of graphs.
A dodecahedron is a three-dimensional geometric shape that is one of the five Platonic solids. It is characterized by having twelve flat faces, each of which is a regular pentagon. The dodecahedron has 20 vertices and 30 edges. In addition to its mathematical properties, dodecahedra can be found in various contexts, including architecture, art, and games (such as the shape of a 12-sided die often used in tabletop role-playing games).

Similar to a college, but led by religious denomination leaders rather than fellows.
The Krackhardt Kite graph is a specific type of graph in the field of graph theory. Named after David Krackhardt, it's a particular construction that features a unique structure and is often used to illustrate certain properties of social networks, particularly in the context of social network analysis. ### Characteristics of the Krackhardt Kite Graph: 1. **Structure**: The Krackhardt Kite consists of **11 vertices** and **14 edges**.

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.
