-yllion by Wikipedia Bot 0
The suffix "-yllion" is not a standard term in mathematics or the sciences, but it seems to be a playful or informal way to refer to large numbers, particularly in the context of "illion" suffixes that denote powers of ten.
Mathematical typefaces refer to specific styles and designs of fonts and symbols that are used for typesetting mathematical notation. These typefaces are designed to meet the unique requirements of mathematical expressions, which often include a wide variety of symbols, characters, and formatting styles that are not typically found in standard text typography.
Mathematical symbols are characters or notations used to represent mathematical concepts, operations, relationships, and quantities. They serve as a universal language that allows mathematicians and scientists to communicate ideas clearly and concisely.
Markov chains are mathematical models that describe systems that transition from one state to another in a memoryless manner, meaning the next state depends only on the current state and not on the previous states. Here are some common examples of Markov chains in various fields: 1. **Game of Monopoly**: The positions of players on a Monopoly board can be modeled as a Markov chain, where each space on the board represents a state.
The Universal Parabolic Constant, often denoted by the symbol \( p \), is a mathematical constant defined as the ratio of the length of a parabola's arc segment to the length of its vertical projection. More specifically, for a parabola described by the equation \( y = x^2 \), the constant is derived from the comparison between the arc length of the curve and the distance along the vertical from the origin to a given point on the parabola.
Square root of 7 by Wikipedia Bot 0
The square root of 7 is approximately 2.64575131106.
Square root of 2 by Wikipedia Bot 0
The square root of 2 is an irrational number approximately equal to 1.41421356237. It is often represented as √2. This value cannot be expressed as a simple fraction, and its decimal representation goes on infinitely without repeating.
Sophomore's dream by Wikipedia Bot 0
The "Sophomore's Dream" is a term used in mathematics, particularly in the context of number theory. It refers to a specific type of mathematical problem or equation related to the sums of squares and their properties. More specifically, it describes the scenario where a number can be expressed as the sum of two squares in more than one way.
The Ramanujan–Soldner constant is a mathematical constant denoted by the symbol \( L \) and is approximately equal to \( 0.781072... \). It is defined as the unique positive root of the logarithmic integral function \( \text{Li}(x) = 0 \).
The Meissel–Mertens constant, often denoted as \( M \), is a mathematical constant that arises in number theory, particularly in the study of prime numbers and the distribution of primes.
A mathematical constant is a fixed, well-defined number that is significant in mathematics. Unlike variables, which can change values, constants remain the same. They often arise in various mathematical contexts and can represent fundamentally important quantities. Examples of widely known mathematical constants include: 1. **Pi (\( \pi \))**: Approximately equal to 3.14159, it represents the ratio of the circumference of a circle to its diameter.
Magic angle by Wikipedia Bot 0
The "magic angle" is a term used primarily in the context of nuclear magnetic resonance (NMR) spectroscopy and solid-state NMR. It refers to a specific angle, approximately 54.74 degrees (or arccos(1/√3)), at which the anisotropic interactions in a solid sample can be effectively averaged out. This is particularly relevant for studying solid materials where the molecular orientations can lead to broadening of NMR signals.
MRB constant by Wikipedia Bot 0
The MRB constant, or the Molar Reference Boiling point constant, is a value used in thermodynamics and physical chemistry to describe the boiling point of substances at a standard pressure, typically 1 atmosphere. It is particularly relevant for understanding the behavior of substances during phase transitions and in the context of calculations involving colligative properties.
The Lemniscate constant, often denoted by the symbol \( L \), is a mathematical constant that arises in connection with the geometry of the lemniscate, a figure-eight shaped curve.
The Landau–Ramanujan constant, usually denoted as \( g \), is a mathematical constant that arises in the context of the theory of numbers, particularly in relation to the asymptotic density of square-free integers. It is named after mathematicians Edmund Landau and Srinivasa Ramanujan.
Hermite constant by Wikipedia Bot 0
The Hermite constant is a mathematical concept in the field of number theory and geometry, particularly in relation to lattices in Euclidean spaces.
The mathematical constant \( e \) is approximately equal to 2.71828 and is the base of the natural logarithm. It is an important constant in mathematics, particularly in calculus and complex analysis, because it has many interesting properties.
Degree (angle) by Wikipedia Bot 0
A degree is a unit of measurement for angles. It is commonly used in various fields, including mathematics, engineering, navigation, and meteorology. One complete rotation around a point is divided into 360 degrees. In the context of angles: - A right angle measures 90 degrees. - A straight angle measures 180 degrees. - A full rotation (complete revolution) measures 360 degrees. Degrees can also be expressed in terms of fractions or as decimal values.
The De Bruijn–Newman constant, denoted as \(\Lambda\), is a concept in number theory and analytic number theory related to the distribution of prime numbers. It arises in the context of the Riemann zeta function and its generalizations.
The 97.5th percentile point in a dataset or distribution is the value below which 97.5% of the observations fall. In other words, if you were to rank all the data points in ascending order, the 97.5th percentile would be the point at which only 2.5% of the data points are higher.

Pinned article: ourbigbook/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.
