Diophantine equations are a class of polynomial equations for which we seek integer solutions. Named after the ancient Greek mathematician Diophantus, these equations are typically of the form: \[ P(x_1, x_2, ..., x_n) = 0 \] where \( P \) is a polynomial with integer coefficients, and \( x_1, x_2, ..., x_n \) are unknown variables that we want to solve for in the integers.
Number theorists are mathematicians who specialize in the field of number theory, which is a branch of pure mathematics focused on the study of the properties and relationships of integers. Number theory encompasses a variety of topics, including: 1. **Prime Numbers**: Study of prime numbers, including their distribution, properties, and related theorems (such as the Prime Number Theorem).
Unsolved problems in number theory are deep questions and conjectures about integers and their properties that have not yet been resolved. Some of the most famous unsolved problems in this field include: 1. **The Riemann Hypothesis**: This conjecture concerns the distribution of the zeros of the Riemann zeta function and has profound implications for the distribution of prime numbers.
In topology, a **generic point** is a concept used to describe a point that represents a subset of a topological space in a broad or "generic" sense. Specifically, a point \( x \) in a topological space \( X \) is called a generic point of a subset \( A \) of \( X \) if every open set containing \( x \) intersects \( A \) in a non-empty set.
A Polish space is a concept from the field of topology and descriptive set theory. Specifically, a Polish space is a topological space that is separable (contains a countable dense subset) and completely metrizable (can be endowed with a metric that induces its topology and is complete, meaning every Cauchy sequence converges within the space).
Software development philosophies refer to the guiding principles, methodologies, and approaches that influence how software is designed, developed, and maintained. These philosophies can shape the practices and culture of development teams and organizations, affecting everything from project management to coding standards and team collaboration. Here are some of the most prominent software development philosophies: 1. **Agile**: Agile is a collaborative and iterative approach that emphasizes flexibility, customer involvement, and rapid delivery.
Robert S. Roth could refer to several individuals, but without more context, it's difficult to provide specific information as there may be multiple people with that name. He could be a professional in various fields such as law, academia, or business. If you have a specific context or domain in which you are searching for more information about Robert S.
GeneMark is a software tool used for gene prediction in prokaryotic and eukaryotic genomes. Developed by the bioinformatics researcher Mark Borodovsky and his colleagues, GeneMark utilizes statistical models to identify potential genes based on sequences in the genome. The software employs methods such as Hidden Markov Models (HMMs) and language-like models to differentiate coding regions (genes) from non-coding regions based on sequence characteristics.
Dixon's identity is a mathematical identity that relates determinants of matrices in the context of combinatorics and the theory of alternating sums. It provides a way to express certain sums of products of binomial coefficients. The identity can be stated in several equivalent forms but is often presented in the context of determinants of matrices whose entries are binomial coefficients.
A **baguenaudier** is a type of mechanical puzzle or toy that consists of a series of interconnected pieces that can be manipulated to create different configurations. The term is derived from the French word "baguenaudier," which translates to "a fooler" or "a trickster," referring to the tricky nature of the puzzle. The most common form of a baguenaudier consists of a set of rods or links that move around a central pivot point.

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.
    Figure 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
