Omar Khayyam was an 11th-century Persian mathematician, astronomer, and poet, best known for his quatrains (rubaiyat), which reflect on various themes including love, mortality, and the nature of existence. His most famous work is the "Rubaiyat of Omar Khayyam," a collection of verses that often express a hedonistic outlook on life, urging the reader to seize the day and enjoy life while they can.
"Lindy" is a contemporary opera composed by the American composer and conductor, William Bolcom, with a libretto by Mark Campbell. The opera premiered in 2017 and is inspired by the life of Charles Lindbergh, the famous aviator known for his historic solo transatlantic flight in 1927.
Network theory is a field of study that examines the structure, dynamics, and properties of networks, which are composed of nodes (vertices) and edges (connections between nodes). It is an interdisciplinary area that draws from mathematics, physics, computer science, sociology, biology, and other domains to analyze how entities (such as individuals, organizations, or genes) interact through their relationships.
The Verhoeff algorithm is an error detection method used primarily for validating identifiers, such as in various forms of numerical codes (e.g., ISBNs, credit card numbers, etc.). It is particularly good at catching single-digit errors, adjacent transpositions, or even some types of multiple errors. ### Key Features of the Verhoeff Algorithm: 1. **Base**: The algorithm operates in base 10, which means it uses the digits 0-9.
Bond energy, also known as bond dissociation energy, is the amount of energy required to break one mole of a particular type of bond in a molecule in the gas phase. It is a measure of the strength of a chemical bond; the higher the bond energy, the stronger the bond between the atoms. Bond energy is usually expressed in kilojoules per mole (kJ/mol) and can vary depending on the molecular environment and the specific atoms involved.
The EURO Journal on Decision Processes is an academic journal that focuses on decision-making processes in various contexts. It is published by Springer and is affiliated with the Association of European Operational Research Societies (EURO). The journal aims to provide a platform for the dissemination of research related to decision-making methodologies, theories, and applications across different fields such as operations research, management science, and related disciplines.
Program Evaluation and Review Technique (PERT) is a project management tool used to analyze and represent the tasks involved in completing a given project. It was developed in the 1950s for the Polaris submarine project and is especially useful for projects with uncertain activity durations. ### Key Features of PERT: 1. **Graphical Representation**: PERT uses a flowchart-like diagram to represent project tasks and their interrelationships. Each task is depicted as a node or a milestone.
Aventurescence is a term used primarily in the context of gemstones and minerals to describe a unique optical phenomenon that occurs when tiny inclusions within a stone reflect and refract light, giving the material a shimmering or sparkling effect. This effect is often seen in stones like aventurine quartz, where the inclusions, often made of mica or hematite, create a glittering appearance.
M. Parker Givens is a figure notable for his work in finance and entrepreneurship, particularly as a private investor and advisor. His focus is often on business strategy, investment opportunities, and helping startups or emerging companies navigate financial challenges. If there are specific aspects or contributions of M.
"German opticians" could refer to several things, primarily focusing on the optical industry in Germany. Here are a few interpretations of the term: 1. **Optical Stores/Practices**: It may refer to retail shops or practices in Germany that specialize in selling eyeglasses, contact lenses, and providing vision care services. These shops typically employ trained opticians who assist customers with eyewear needs.
The Helmholtz–Kohlrausch effect refers to a perceptual phenomenon in which the color of a light source appears to change relative to its surrounding colors. Specifically, it describes how the brightness of a color can influence the perception of its hue, particularly when that color is against a background of varying luminance or chromaticity. This effect, named after the physicists Hermann von Helmholtz and Wilhelm Kohlrausch, highlights the complex relationship between color perception, brightness, and contrast.
A "wake low" is a meteorological phenomenon that occurs in the wake of a large storm system, such as a hurricane or a mid-latitude cyclone. It is characterized by a localized area of low pressure that forms downwind of the main low-pressure system. This phenomenon is typically associated with strong winds and heavy precipitation.
Gong Zutong is a term that refers to a type of traditional Chinese woodblock printing technique. The phrase can literally translate to "official printing" or “government printing”. It typically involves printing techniques used for producing official documents, texts, or sometimes cultural items that hold significance within Chinese history and art. In the context of Chinese culture, woodblock printing has been used for centuries to reproduce texts and images, contributing significantly to the dissemination of literature, art, and religious texts.
Opalescence is a brand of teeth whitening products manufactured by Ultradent Products, Inc. The line includes various formulations for at-home and in-office whitening treatments. Opalescence products are known for their active ingredient, potassium nitrate and fluoride, which help to reduce tooth sensitivity while whitening.

Dan D. Yang is a name that may refer to various individuals or contexts, but there is no widely recognized figure or concept by that specific name in popular culture or academia up to my last update in October 2023.

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
