Paper football is a simple tabletop game typically played by two players using a small folded paper triangular "football." The objective of the game is to score points by flicking the paper football across a playing surface (usually a table) and trying to get it to land in an end zone or on a goalpost that is represented by players' fingers or other markers. ### Basic Rules of Paper Football: 1. **Setup**: Players sit opposite each other.
The Game Theory Society is an organization that promotes the study and application of game theory, a mathematical framework for analyzing strategic interactions among rational decision-makers. Established to foster collaboration and research within this field, the society aims to encourage the development and dissemination of new ideas, methods, and applications of game theory across various disciplines, including economics, political science, biology, and computer science.
Cayley's theorem is a fundamental result in group theory, a branch of abstract algebra. It states that every group \( G \) is isomorphic to a subgroup of the symmetric group \( S_n \), where \( n \) is the order (number of elements) of the group \( G \).
Circular permutation in proteins refers to a specific type of structural rearrangement where the N-terminus and C-terminus of a protein are joined to form a continuous loop. In this process, the sequence of amino acids may be rearranged such that regions of the protein that were originally at the N-terminus and the C-terminus are now adjacent in the circular form. This can result in a protein that has new termini but is still functionally similar to the original linear version.
Cambiata is a musical term that refers to a voice-changing or transitional period, especially in the context of choral music. It typically pertains to the voice of a male singer during adolescence, when changes in vocal range occur as the singer transitions from a treble voice to a more mature, lower tenor or bass voice. In a choral setting, Cambiata voices are often described as being in between the treble and tenor ranges.
Diminution generally refers to the process of becoming smaller or less in amount, value, quality, or intensity. The term can be applied in various contexts: 1. **General Use**: In everyday language, it simply denotes a reduction or decrease in size or degree. 2. **Legal Context**: In legal terms, diminution often refers to a decrease in property value due to factors such as damage, market conditions, or other external influences.
Foldscope is an innovative, low-cost optical microscope developed to enable scientific exploration and education, particularly in resource-limited settings. It was created by a team of researchers led by Manu Prakash at Stanford University. The design of the Foldscope allows it to be made from a simple sheet of paper embedded with optical components, which can be folded into a functional microscope.
The term "chronotope" is a concept introduced by Russian literary theorist Mikhail Bakhtin in his work on the philosophy of language and narrative. The word is a blend of "chrono," meaning time, and "topos," meaning space. In Bakhtin's framework, a chronotope refers to the intrinsic interconnectedness of temporal and spatial relationships in a narrative. It highlights how time and space are represented and constructed in literature, shaping characters, events, and themes.
Non-linguistic meaning refers to the conveyance of significance, understanding, or interpretation that occurs without the use of language or linguistic elements. This type of meaning can be expressed through various forms, including: 1. **Visuals**: Images, symbols, and diagrams can communicate concepts or emotions (e.g., a heart symbol representing love). 2. **Gestures**: Body language, facial expressions, and hand signals can express feelings or intentions (e.g., a thumbs up indicating approval).
Edward Olson Hulburt is not widely recognized in popular culture, science, or history, at least up to my knowledge cutoff in October 2023. It's possible he may be a private individual or associated with a niche area not covered by mainstream sources.
"Trill" in music refers to a specific vocal technique commonly used in various genres, particularly in hip-hop and R&B. It is characterized by the rapid alternation between two pitches, creating a rapid, fluttering sound. The term combines "true" and "real," reflecting a sense of authenticity and genuine expression in the music.
The \( p \)-adic exponential function is an important concept in \( p \)-adic analysis, which is a branch of mathematics that deals with \( p \)-adic numbers. The \( p \)-adic numbers are a system of numbers that extend the rational numbers and provide a different perspective on number theory and algebra.
"A History of Folding in Mathematics" is not a specific title of a well-known book or article, but the topic it refers to relates to the mathematical study of folding, which intersects with various areas such as geometry, topology, and computational mathematics. The concept of folding can be explored in several contexts. For instance: 1. **Origami**: The mathematical study of origami has gained significance over the years.
The Big-Little-Big Lemma is a result in number theory, particularly in the area of prime number theory and additive combinatorics. This lemma typically relates to the distribution of primes and the structure of integer sequences. The lemma asserts that if we have a prime p that divides a certain expression involving integers, and if we also have a prime q not dividing the same primes, then we can draw conclusions about the divisibility or arithmetic properties of sequences or sums involving these primes.
Kawasaki's theorem is a result in the field of differential geometry, particularly concerning Riemannian geometry and the construction of Riemannian manifolds. It specifically deals with the conditions under which a certain type of surface can be isometrically immersed in Euclidean space.
The Schwarz lantern is a geometric object that serves as a counterexample in the field of topology and differential geometry. It demonstrates that certain intuitively reasonable assumptions about the properties of manifolds cannot be universally applied. Specifically, the Schwarz lantern is constructed to show that it is possible to have a collection of regions in a compact manifold, each of which can be continuously deformable to a simpler shape, that do not yield a manifold with the desired topological properties when combined.
Origamics is a creative field that combines origami, the art of paper folding, with principles of engineering, mathematics, and design to create complex and innovative structures. The term "origamics" is often used to describe the study and application of foldable and deployable structures that can transform from a compact state to a larger, functional form.
A random permutation is a rearrangement of a finite sequence of elements where each possible arrangement is equally likely. In other words, if you have a set of \( n \) distinct elements, a random permutation is one of the \( n! \) (n factorial) possible orderings of those elements chosen uniformly at random. For example, consider the set of elements \( \{1, 2, 3\} \).
Allocative efficiency is an economic concept that occurs when resources are distributed in such a way that maximizes the total benefit received by all members of society. In other words, it refers to a situation where the quantity of each good or service produced is exactly what consumers want to consume, reflecting the highest utility or satisfaction. Allocative efficiency is achieved when the price of a good or service is equal to the marginal cost of producing it.
Acceleration is a vector quantity that measures the rate of change of velocity of an object over time. It indicates how quickly an object is speeding up, slowing down, or changing direction.

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.
