The term "Dark Siren" can refer to a variety of concepts depending on the context. Here are a few possible interpretations: 1. **Mythological Reference**: In mythology, sirens are often depicted as alluring creatures that lure sailors to their doom with enchanting music and voices. A "dark siren" might imply a particularly malevolent or sinister version of this archetype, perhaps associated with themes of seduction and danger.
"Icterine" generally refers to a color or characteristic associated with a yellowish hue, often seen in various contexts such as botany or ornithology. The term is derived from the Latin word "icterus," which means jaundice, referring to the yellow coloring associated with that condition. In botany, "icterine" might be used to describe certain plants or flowers that exhibit a yellow color.
The Ostriker–Peebles criterion is a criterion in astrophysics used to evaluate the stability of spherical systems of matter under gravitational collapse, particularly in the context of galaxy formation and the large-scale structure of the universe. It is named after the astronomers J. P. Ostriker and P. J. E. Peebles. The criterion assesses whether a system, such as a cloud of gas or a cluster of galaxies, is stable against perturbations.
The Perseus–Pegasus Filament is a large-scale structure in the universe, specifically a cosmic filament, that is part of the larger cosmic web. It is a region in space where galaxies are distributed along elongated structures, often forming a network of interconnected strands, or filaments, that are separated by voids. This filament lies in the direction of the constellations Perseus and Pegasus and is known for its high density of galaxies.
The term "Shapley Attractor" is often associated with concepts in game theory and economics, particularly in the context of cooperative games and the allocation of resources. However, the phrase may also appear in other scientific fields such as dynamical systems and ecology. In the context of game theory, the Shapley value, developed by Lloyd Shapley, is a solution concept that assigns a value to each player based on their contributions to the total payoff.
The Giant Arc refers to a massive cosmic structure discovered in recent astronomical surveys. It is characterized as a large-scale arrangement of galaxies and galaxy clusters that spans a significant portion of the observable universe. The Giant Arc stretches for about 3.3 billion light-years and is notable for containing a relatively low density of matter compared to other regions.
Alpha Centauri is often depicted in science fiction as a neighboring star system to our own, primarily due to its proximity—about 4.37 light years away from Earth. This makes it an attractive setting for various speculative stories, as it is one of the closest systems that could potentially harbor planets and life.
Project Longshot is a theoretical concept for a spacecraft designed to explore the Alpha Centauri star system, which is the closest known star system to Earth, located about 4.37 light-years away. The project was initially conceived by NASA in collaboration with the US Naval Academy in the 1980s. It aimed to develop a spacecraft capable of making the journey to Alpha Centauri within a human lifetime.
The base curve radius (BCR) is an important measurement in the field of optics, particularly in the design and fitting of contact lenses and eyeglasses. It refers to the curvature of the back surface of a contact lens or the front surface of a spectacle lens. In the context of contact lenses, the base curve radius is measured in millimeters (mm) and indicates how curved the lens is.
MOCADI stands for Modular Open-Source Cognitive Architecture for Developmental Interaction. It is a framework designed for developing interactive agents and robots that can learn, adapt, and interact with humans and their environment in a more natural and intuitive way. The MOCADI framework emphasizes modularity and open-source principles, allowing developers and researchers to contribute to its evolution and customize it for specific applications. MOCADI may be used in various domains, including robotics, artificial intelligence, and cognitive modeling.
Molecular physics is a subfield of physics that focuses on the physical properties and behavior of molecules. It encompasses the study of molecular structures, interactions, and dynamics, as well as the underlying principles that govern these phenomena. Key areas of interest in molecular physics include: 1. **Molecular Structure:** Understanding the arrangement of atoms within a molecule and how chemical bonds form, including the study of molecular geometry, hybridization, and bonding theories.
Aqua is a color that refers to a bluish-green hue, reminiscent of the color of tropical waters. It is often associated with freshness, tranquility, and clarity. In terms of the RGB color model, aqua is created by combining green and blue light at full intensity, resulting in the RGB value of (0, 255, 255) or hex code #00FFFF.
The term "Color Quality Scale" (CQS) refers to a metric used to evaluate the color quality of light sources, particularly artificial lighting like LEDs and fluorescent lamps. It was developed as an alternative to the Color Rendering Index (CRI), which has limitations in assessing how well a light source reproduces colors in comparison to natural light. The CQS aims to provide a more comprehensive understanding of how light sources affect the appearance of colors in various settings.

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 5. . You can also edit articles on the Web editor without installing anything locally.
