M. C. Escher, whose full name is Maurits Cornelis Escher, was a Dutch graphic artist known for his mathematically inspired works. Born on June 17, 1898, in Leeuwarden, Netherlands, and passing away on March 27, 1972, in Hilversum, Netherlands, Escher is renowned for his intricate and imaginative prints that feature impossible constructions, explorations of infinity, symmetry, and tessellations.
Mathematical relations refer to the ways in which different mathematical entities are connected or associated with one another. In mathematics, a relation is essentially a set of ordered pairs that describe a relationship between two sets of elements. Here are some key concepts related to mathematical relations: 1. **Definition**: A relation from a set \( A \) to a set \( B \) is a subset of the Cartesian product \( A \times B \).
"Statistician stubs" typically refer to short articles or entries related to statisticians that are incomplete or underdeveloped on platforms like Wikipedia. In the context of online collaborative encyclopedias, a "stub" is a page that provides only a minimal amount of information about a subject. These stubs are often marked with a "stub" template to indicate that they need expansion and additional content.
The Fuss–Catalan numbers are a generalization of the Catalan numbers. They count certain combinatorial structures that can be generalized to several parameters.
Graph enumeration is the field of study in combinatorial mathematics and computer science focused on counting, listing, and studying the properties of different types of graphs. A graph is a mathematical structure consisting of vertices (or nodes) connected by edges. Graph enumeration involves exploring how many distinct graphs can be formed under various conditions and constraints.
"Statisticians by field" refers to the different areas or domains in which statisticians apply their skills and expertise. Statisticians work in a variety of industries and sectors, each with its own specific needs and applications for statistical analysis.
Inca mathematics refers to the numerical and logistical systems used by the Inca Empire, which thrived in the Andean region of South America from the early 15th century until the Spanish conquest in the 16th century. The Incas did not have a written form of mathematics like many other civilizations; instead, they employed a sophisticated system based on the quipu, a device made of colored strings and knots that served as a means of record-keeping and information management.
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.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
