Alfred Inselberg is a notable mathematician recognized for his contributions to various fields, particularly in mathematics and computer science. He is best known for developing the concept of "axis-parallel" and "parallel coordinates," which are techniques for visualizing high-dimensional data. His work in visualization has had significant implications in data analysis, scientific computing, and information visualization. In addition to his work on parallel coordinates, Inselberg has contributed to other areas, including algebra, geometry, and computer graphics.
Magoroh Maruyama is a prominent figure in the field of education, particularly known for his work on the Theory of Educational Change. He is recognized for introducing concepts related to educational innovation, school reform, and the learning community. His contributions often focus on how to implement effective changes in educational systems and how to foster environments that enhance learning outcomes for students. Maruyama’s work emphasizes the importance of collaboration and a holistic approach to education.
As of my last knowledge update in October 2023, there isn't widely known information about "Ulla Mitzdorf." It's possible that Ulla Mitzdorf could refer to a lesser-known person, a fictional character, or a recent topic that has emerged after my last update.
Asger Aaboe is a Danish mathematician known for his work in the history of mathematics and the development of mathematical education. He is particularly noted for his contributions to the study of ancient Greek mathematics and the history of arithmetic. Aaboe has written extensively on the history of mathematics, including the influence of Babylonian and Greek mathematics on the development of modern mathematical thought. He has also been involved in various educational initiatives, emphasizing the importance of a historical perspective in understanding mathematics.
Axion can refer to different concepts depending on the context: 1. **Physics**: In particle physics, an axion is a hypothetical elementary particle that is proposed as a solution to the strong CP (Charge Parity) problem in quantum chromodynamics (QCD). It is a lightweight, neutral particle that could help explain why strong interactions do not seem to violate CP symmetry.
Light dark matter refers to a class of hypothetical dark matter candidates that have a relatively low mass compared to traditional dark matter models like Weakly Interacting Massive Particles (WIMPs). While WIMPs are typically on the scale of hundreds of GeV (giga-electronvolts), light dark matter candidates can have masses that are much smaller, often in the range of a few MeV (mega-electronvolts) to a few GeV.
The Runge-Gross theorem is a fundamental result in the field of many-body quantum mechanics, specifically in the context of time-dependent density functional theory (TDDFT). It establishes a mathematical connection between the time-dependent electron density of a system and the external potential acting on it.
A Homogeneously Suslin set refers to a specific type of subset of a Polish space (a separable completely metrizable topological space), particularly in the context of descriptive set theory. The notion is related to the concepts of Suslin sets and the general theory of analytic sets. A subset of a Polish space is called a Suslin set if it can be obtained from Borel sets through a continuous image or by countable unions and intersections.
Differential algebraic geometry is a field of mathematics that combines concepts from differential geometry and algebraic geometry. Specifically, it studies sets of algebraic equations and inequalities that define geometric objects and incorporates differentiability conditions. Here are some of the key components and concepts related to differential algebraic geometry: 1. **Algebraic Geometry**: This branch of mathematics focuses on the study of geometric properties of solutions to polynomial equations.
"Software wars" generally refers to the competitive landscape and conflicts among software companies, technologies, or platforms in various sectors of the tech industry. This term can apply to several contexts: 1. **Operating Systems**: The competition between major operating systems like Microsoft Windows, macOS, and various distributions of Linux can be described as software wars, as each system strives for market dominance and user preference. 2. **Application Software**: Various applications compete for user attention and market share.
Birch's theorem, also known as the Birch and Swinnerton-Dyer conjecture, is a famous conjecture in number theory related to elliptic curves. It posits a deep relationship between the number of rational points on an elliptic curve and the behavior of an associated L-function.
Wooden dolls are handcrafted toys made primarily from wood and are often used as playthings for children or as decorative items. These dolls can vary widely in design, size, and purpose, but they typically feature articulated limbs and painted or carved facial features. Historically, wooden dolls have been made in various cultures around the world, often reflecting local traditions, attire, and craftsmanship. In addition to being toys, they have sometimes served as cultural artifacts, educational tools, or collector's items.
Egli-Figuren, often referred to in English as "Egli figures" or "Egli curves," are a type of geometric figure used primarily in descriptive geometry and engineering drawing. They are named after Swiss architect and artist Hans Egli, who developed a method for representing three-dimensional forms in two-dimensional drawings. Egli figures serve to depict the spatial relationship between different components or systems, making complex structures easier to understand and visualize.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
