In topology, the concept of an "end" provides a way to classify the asymptotic behavior of a space at infinity. More formally, an end of a topological space can be understood as a way to describe how the space can be "accessed" from large distances.
Gerhard Neukum is a notable figure in the field of astronomy and planetary science, particularly known for his work on planetary geoscience and astrobiology. He has been involved in various NASA missions, including those related to asteroids and other celestial bodies. His research often focuses on the impacts of space weather and the geological processes on different planetary bodies.
Computer cartography is the use of computer technology to create, analyze, and manipulate maps and geographic information. It involves the application of software and tools to generate cartographic representations of spatial data, allowing for a more efficient and accurate way to visualize geographic information. Key components of computer cartography include: 1. **GIS (Geographic Information Systems)**: These systems are integral to computer cartography and are used for capturing, storing, analyzing, and managing spatial data.
A computer poker player is an artificial intelligence (AI) program or algorithm designed to play poker against human players or other AI opponents. These programs use various strategies and techniques to make decisions during the game, such as betting, raising, calling, or folding. Key features of computer poker players include: 1. **Game Theory**: Many advanced poker AI systems are built upon game theory principles, which help them understand optimal strategies and counter-strategies.
The German Network for Bioinformatics Infrastructure (de.NBI) is a collaborative initiative that aims to provide bioinformatics services, resources, and expertise for researchers in Germany and beyond. Established to support the growing field of bioinformatics, de.NBI offers a wide range of tools and services that facilitate the analysis and interpretation of biological data. Key components of de.NBI include: 1. **Infrastructure**: de.
Conformal welding is a specialized joining technique primarily used in the field of electronics and materials science. It involves creating a bond between two materials using a conformal approach, which means the assembly process adapts to the contours of the components being joined. This method often employs the use of conductive adhesives or materials that have been specifically designed to flow and take the shape of the surfaces they adhere to.
The term "conical function" does not refer to a standard mathematical concept or function that is widely known or recognized. However, it is possible that the term could be related to functions that describe geometrical properties of cones or are associated with conic sections (such as parabolas, ellipses, and hyperbolas).
In the context of isometries in Euclidean space, conjugation refers to the operation that modifies an isometry by another isometry, often to understand how certain properties change under transformations. An isometry is a distance-preserving transformation, which can include translations, rotations, reflections, and glide reflections. In Euclidean space, we can represent isometries using linear transformations (matrices) and translations (vectors).
The term "Connected category" can refer to different concepts depending on the context in which it is used. Here are a couple of possible interpretations based on different fields: 1. **In Graph Theory**: A connected category might refer to a graph where there is a path between any two vertices. In this case, "connected" means all points (or nodes) in the graph are reachable from one another.
C. S. Seshadri, or Chellathur Seshadri, was a prominent Indian mathematician known for his significant contributions to several areas of mathematics, particularly in algebraic geometry and its connections to number theory. He is best known for his work in the theory of moduli spaces and for the Seshadri constant, which is an important concept in the study of vector bundles and stability conditions.
A consensus sequence is a sequence of nucleotides (in DNA or RNA) or amino acids (in proteins) that represents the most common or shared residue found at each position in a multiple sequence alignment. It highlights the most typical or representative features of a set of sequences that may demonstrate variability at each position. In the context of molecular biology, consensus sequences are often used to identify conserved regions that may be critical for function, such as binding sites for proteins or essential motifs within DNA regulatory regions.

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
