The selenographic coordinate system is a framework used for mapping and specifying locations on the Moon's surface, similar to how terrestrial coordinates (latitude and longitude) are used for Earth. In the selenographic system, the coordinates are defined as follows: 1. **Latitude**: Measured in degrees north or south of the lunar equator, just like Earth.
A network model is a conceptual and mathematical framework used to represent and analyze interactions among various elements or entities within a system. It is widely used across various fields, including computer science, telecommunications, social sciences, and operations research. Below are some key aspects of network models: ### 1. **Structure**: - **Nodes** (or Vertices): These represent the individual entities or elements in the network. For example, in a social network, nodes could represent people or organizations.
A Toeplitz operator is a type of linear operator that arises in the context of functional analysis, particularly in the study of Hilbert spaces and operator theory. Toeplitz operators are defined by their action on sequences or functions, and they are often associated with Toeplitz matrices.
Blue phase mode LCD is a type of liquid crystal display technology that utilizes a specific phase of liquid crystals known as "blue phase." This phase is characterized by its unique optical properties and ability to switch states quickly, making it suitable for various display applications. ### Key Features of Blue Phase Mode LCD: 1. **Fast Response Time:** Blue phase mode liquid crystals can switch between different states much faster than traditional twisted nematic (TN) or even in-plane switching (IPS) display technologies.
The Jupiter trojans are a group of asteroids that share an orbit with Jupiter, located at the Lagrange points L4 and L5, which are approximately 60 degrees ahead of and behind Jupiter in its orbit around the Sun. The Greek camp refers to those trojans whose names are derived from characters from Greek mythology, particularly those associated with the Trojan War.
Nematicon is a type of optical switch that uses liquid crystals to control the passage of light. Typically, it consists of a device that can manipulate the light's properties, such as its intensity or phase, by adjusting the orientation of liquid crystal molecules in response to an electric field. This technology leverages the unique characteristics of liquid crystals, allowing for rapid switching and potential applications in telecommunications, displays, and other optical systems.
Dynamic modality typically refers to the concept of expressing necessity and possibility in varying contexts, often in relation to ability, capacity, or permission that can change based on circumstances. This concept is commonly found in linguistics, philosophy, and modal logic. In linguistics, dynamic modality deals with the ways in which verbs and expressions can capture the idea of actions that are possible or necessary due to the abilities of the subject, rather than being strictly about what is logically or factually required.
GNOME LaTeX is a graphical user interface (GUI) front-end for creating and managing LaTeX documents. It is part of the GNOME desktop environment and is designed to help users, especially those who may not be familiar with LaTeX, to easily write, compile, and preview LaTeX documents.
Kile is a user-friendly LaTeX editor for the KDE desktop environment, primarily used on Linux systems. It provides a graphical interface for creating and editing LaTeX documents, which are commonly used for typesetting documents that require complex formatting, such as academic papers, theses, and dissertations. Kile offers features such as: - Intuitive user interface with toolbars and menus for common tasks. - Built-in templates for different types of documents.
The International Liquid Crystal Society (ILCS) is an organization dedicated to promoting the science and technology of liquid crystals. Established in 1980, the society facilitates communication and collaboration among researchers, scientists, and industry professionals involved in the study and application of liquid crystal materials. ILCS typically organizes conferences, workshops, and symposia to share the latest research findings, developments, and innovations in the field.
Paranematic susceptibility refers to the response of a nematic liquid crystal to an external electric or magnetic field, particularly in terms of its alignment or orientation. In the context of liquid crystals, "paranematic" generally refers to a state where the liquid crystal molecules are predominantly aligned in a certain direction but not as ordered as in a fully nematic phase. The susceptibility aspect indicates how much the orientation of the liquid crystal is affected by the external field.
The American Physical Society (APS) recognizes outstanding contributions to the field of physics by electing members to the status of Fellow. The list of APS Fellows includes physicists who have made significant contributions in various areas of physics, including research, education, and outreach.
Asteroid impact prediction is the process of assessing the likelihood that an asteroid will collide with Earth or another celestial body. This involves a variety of scientific techniques and methods to track and calculate the orbits of asteroids, analyze their physical properties, and predict their potential paths over time. Key components of asteroid impact prediction include: 1. **Observational Data**: Astronomers use telescopes and other instruments to detect and monitor asteroids.
The Jupiter trojans are a group of asteroids that share Jupiter's orbit around the Sun, located at the L4 and L5 Lagrange points, which are 60 degrees ahead of and behind Jupiter in its orbit, respectively. The trojans are traditionally named after characters from Greek mythology. The specific list of Jupiter trojans in the range of 100001 to 200000 includes several asteroids.
As of my last update in October 2023, the Army Black Knights men's basketball team's statistical leaders typically include top players in various categories such as points, rebounds, assists, steals, and blocks. However, these statistics can change frequently with each season.
The American Eagles men's basketball statistical leaders include players who have achieved significant milestones in various categories such as points, rebounds, assists, steals, and blocks.
In 2016, several asteroids made close approaches to Earth. Here's a list of some notable ones: 1. **2016 AJ193** - This asteroid had a close approach on 2016 January 12, coming within 0.017 AU (approximately 6.6 Earth radii). 2. **2016 BX43** - Came close on 2016 January 23, with a distance of about 0.007 AU.

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
