The discrepancy of hypergraphs is a concept in combinatorial mathematics that deals with how evenly one can color or distribute a set of points (or elements) among different subsets (or hyperedges) of a hypergraph. More formally, it is concerned with the maximum imbalance that can arise when assigning colors, typically two colors, to the vertices of the hypergraph with respect to the hyperedges.
The Beck–Fiala theorem is a result in the field of combinatorial geometry, specifically concerning the covering of points by convex sets.
The term "Royal Clock" can refer to several different things, depending on the context in which it is used. Here are a few possible interpretations: 1. **Horological Devices**: In a general sense, "Royal Clock" might refer to elaborate timepieces that have historical significance or are associated with royal families. These can be intricate clocks made for monarchs or those that are housed in royal palaces.
The "Nutshell Studies of Unexplained Death" is a collection of dioramas created by Frances Glessner Lee in the 1940s. Glessner Lee was a pioneer in forensic science who aimed to improve the training of homicide investigators. The dioramas are incredibly detailed miniature scenes that depict various murder mysteries and unexplained deaths. Each diorama is designed to present a different set of circumstances surrounding a fictional death, complete with realistic props and meticulous attention to detail.
A Nativity scene, also known as a creche or mangers, is a depiction of the birth of Jesus Christ, primarily used as a visual representation of the Nativity story from the Christian tradition. These scenes typically include figures representing key characters such as: - **Baby Jesus:** Often depicted in a manger or cradle. - **Mary:** The mother of Jesus, usually shown near her child. - **Joseph:** Mary's husband, often portrayed standing protectively by them.
The Museum of the Gorge is a local museum located in Ironbridge, Shropshire, England. It is part of the Ironbridge Gorge World Heritage Site, which is known for its historical significance in the development of the iron and coal industries during the Industrial Revolution. The museum is dedicated to showcasing the history and heritage of the Ironbridge Gorge area, particularly its industrial past.
"Man in the Mud" typically refers to a concept or metaphor that illustrates human struggle, resilience, or the complexities of life. It could represent individuals who find themselves in difficult circumstances or "stuck" situations, much like being trapped in mud.
"Lion Attacking a Dromedary" refers to a famous painting by the French artist Antoine-Louis Barye, created in the 19th century. Barye was known for his animal sculptures and paintings, and this particular work depicts the dramatic moment of a lion attacking a dromedary (a one-humped camel). The painting is noted for its dynamic composition and the vivid depiction of the struggle between the powerful predator and its prey.
Illés Relief is a type of relief sculpture characterized by its intricate details and craftsmanship. It refers to a specific artwork that depicts the biblical prophet Elijah (Illés in Hungarian) in a dramatic context, including scenes from his life and miracles. The relief captures the essence of the narrative and emotions associated with the prophet, often showcasing his encounters with nature and divine intervention.
The Holyland Model of Jerusalem is a highly detailed scale model of the city of Jerusalem, representing its landscape and architecture at a specific point in history. Typically, the model depicts Jerusalem as it was during the Second Temple period, around 66 AD. This period is significant in Jewish history, as it was during this time that the Second Temple stood before its destruction by the Romans in 70 AD.
Hippolyte Sébron (1821–1879) was a French painter known for his contributions to the art world during the 19th century. He was primarily associated with the realist movement and is often recognized for his detailed and vibrant landscape paintings, as well as portraits and historical scenes. Sébron was influenced by the naturalistic approach of his contemporaries, and his works often capture the essence of French rural life and the beauty of the countryside.
The Bhagavad-gita Museum is a cultural and spiritual institution dedicated to the teachings of the Bhagavad-gita, a 700-verse Hindu scripture that is part of the Indian epic Mahabharata. The museum typically aims to provide insights into the philosophical, spiritual, and historical aspects of the Bhagavad-gita, which is considered one of the most important texts in Hindu philosophy and spirituality.
The AMNH Exhibitions Lab, part of the American Museum of Natural History (AMNH) in New York City, is an innovative space dedicated to the design, development, and testing of new museum exhibitions. It serves as a collaborative environment where curators, educators, designers, and other professionals can come together to explore and create engaging and educational exhibits that align with the museum's mission to inspire understanding of the natural world and the universe.
A **primitive Pythagorean triple** consists of three positive integers \( (a, b, c) \) that satisfy the equation \( a^2 + b^2 = c^2 \) and have a greatest common divisor (gcd) of 1, meaning they are coprime.
Tijdeman's theorem is a result in number theory concerning the equation \( x^k - y^m = 1 \), where \( x \), \( y \) are positive integers, and \( k \), \( m \) are integers greater than or equal to 2. The theorem states that the only solutions in positive integers \( (x, y, k, m) \) to this equation occur for certain specific values.
The Thue equation is a type of Diophantine equation, which is a polynomial equation that seeks integer solutions. Specifically, a Thue equation has the general form: \[ f(x, y) = h \] where \(f(x, y)\) is a homogeneous polynomial in two variables with integer coefficients, and \(h\) is an integer.
"The Monkey and the Coconuts" is a traditional folk tale that often appears in various cultures, with different versions and details. The story typically involves a group of monkeys and a supply of coconuts that they find. The narrative usually revolves around themes such as intelligence, teamwork, problem-solving, and sometimes morality. In one common version of the tale, a group of monkeys discovers a coconut tree and figures out how to gather the coconuts.

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.
