Undulating number by Wikipedia Bot 0
An undulating number is a number where the digits alternately increase and decrease. More formally, a number is considered undulating if, for every pair of adjacent digits in the number, either the left digit is greater than the right digit or the left digit is less than the right digit, with no two adjacent digits being equal.
Unit function by Wikipedia Bot 0
In mathematics, particularly in linear algebra and functional analysis, the term "unit function" can refer to different concepts depending on the context. Here are a few interpretations: 1. **Unit Function in Physics and Engineering**: In the context of signals, the "unit function" often refers to the unit step function (Heaviside function), which takes the value of 0 for negative inputs and 1 for non-negative inputs.
Waring's prime number conjecture is an extension of Waring's problem, which originally deals with the representation of natural numbers as sums of a fixed number of powers of natural numbers. Specifically, Waring's problem states that for any natural number \( k \), there exists a minimum integer \( g(k) \) such that every natural number can be expressed as the sum of at most \( g(k) \) \( k \)-th powers of natural numbers.
Algebraic numbers by Wikipedia Bot 0
Algebraic numbers are a subset of complex numbers that are roots of non-zero polynomial equations with rational coefficients. In other words, a complex number \( \alpha \) is considered algebraic if there exists a polynomial \( P(x) \) with \( P(x) \in \mathbb{Q}[x] \) (the set of all polynomials with rational coefficients) such that \( P(\alpha) = 0 \).
In politics, "numbering" can refer to several different concepts, depending on the context. Here are a few interpretations: 1. **Numbered Lists of Candidates or Proposals**: In electoral contexts, candidates may be numbered on ballots to facilitate easier identification and voting. This system helps voters quickly locate their preferred candidates among a list. 2. **Polling and Surveys**: Researchers and political analysts often use numbering in surveys and polls to quantify public opinion on various issues, candidates, or policies.
Numeral systems by Wikipedia Bot 0
Numeral systems are methods for expressing numbers in a consistent manner, typically using a set of symbols and a base or radix. Each numeral system has its own rules for representing numerical values. Here are some of the most common numeral systems: 1. **Decimal (Base 10)**: The most commonly used numeral system, employing ten digits (0-9). Each position represents a power of ten.
Ordinal numbers by Wikipedia Bot 0
Ordinal numbers are numbers that indicate the position or rank of an item in a sequence. They are used to describe the order of items, such as first, second, third, and so on. Unlike cardinal numbers, which denote quantity (e.g., one, two, three), ordinal numbers are primarily concerned with the arrangement of items.
Millieme by Wikipedia Bot 0
The term "millieme" refers to a fractional currency unit that is used in some countries, particularly in the Arab world and parts of the Ottoman Empire's legacy. A millieme is typically 1/1000 of a dinar or other primary currency unit, although the specific relationship can vary by country. For example, in Iraq, the millieme was historically used as a subdivision of the dinar.
Large numbers are often named using a system that builds upon powers of ten. Here are some names for various large numbers, primarily based on the short scale, which is more commonly used in the United States and modern English-speaking countries: 1. **Thousand**: \(10^3\) (1,000) 2. **Million**: \(10^6\) (1,000,000) 3.
Number by Wikipedia Bot 0
A number is a mathematical concept that represents a quantity or value. Numbers can be categorized into various types, including: 1. **Natural Numbers**: These are the positive integers starting from 1, 2, 3, and so on (1, 2, 3, ...). 2. **Whole Numbers**: These include all natural numbers and zero (0, 1, 2, 3, ...).
Telephone numbers by Wikipedia Bot 0
Telephone numbers are a series of digits assigned to a telephone line to facilitate communication through the telephone network. Each telephone number is unique and allows the identification of a specific telephone circuit, enabling people to make and receive calls. Telephone numbers typically consist of the following components: 1. **Country Code:** A numeric code that represents a specific country, used when dialing internationally (e.g., +1 for the U.S. and Canada).
Multimagic cube by Wikipedia Bot 0
The term "Multimagic cube" typically refers to a type of mathematical puzzle that extends the concept of a magic square or magic cube into higher dimensions. A magic cube is a three-dimensional arrangement of numbers in which the sums of the numbers in each row, column, and diagonal (in all three dimensions) are equal to a constant known as the magic constant.
Monogenic field by Wikipedia Bot 0
A monogenic field is a concept that arises in the context of algebraic number theory and field theory. The term generally refers to a field extension that is generated by a single element, also known as a primitive element.
Antonia J. Jones by Wikipedia Bot 0
Antonia J. Jones could refer to various individuals or contexts, but without specific details, it's hard to provide a precise answer. If you are referring to a person, they could be an author, academic, or a professional in a certain field. It's also possible that it's a character in a book, a film, or another form of media.
Arnold Walfisz by Wikipedia Bot 0
Arnold Walfisz is not a widely recognized figure in popular culture or academia, at least as of my last knowledge update in October 2023. It's possible that you are referring to a lesser-known individual, or perhaps there has been a development or emergence of a figure by that name since then.
Iron group by Wikipedia Bot 0
The term "iron group" can refer to different concepts depending on the context. Here are two common interpretations: 1. **In terms of chemistry**: The "iron group" often refers to the group of transition metals in the periodic table that includes iron (Fe), cobalt (Co), and nickel (Ni). These metals share similar properties, such as the ability to form various oxidation states, and are often used in alloy production, catalysis, and other industrial applications.
Bill Gosper by Wikipedia Bot 0
Bill Gosper is an American computer scientist and mathematician known for his contributions to various fields, particularly in the areas of computer programming, combinatorial mathematics, and artificial intelligence. He is also recognized for his work related to the Game of Life, a cellular automaton devised by mathematician John Conway. Gosper developed efficient algorithms for simulating the Game of Life and created the term "glider," which refers to a specific pattern that moves across the grid.

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.
