The history of logarithms dates back to the early 17th century and is closely tied to the development of mathematics, particularly in the fields of arithmetic and algebra. Here’s a brief overview of the key developments in the history of logarithms: ### Origins and Development - **Early Concepts**: The concept of logarithms began to take shape as mathematicians sought to simplify complex calculations, particularly multiplication and division. The need for easier computation methods was especially pronounced in astronomy and navigation.
The history of mathematical notation is a fascinating journey that reflects the evolution of mathematics itself, as well as changes in culture, language, and technology. Here’s a brief overview of the key developments in mathematical notation from ancient times to the modern era: ### Ancient Civilizations 1. **Babylonians (c. 2000 BC)**: The Babylonians used a sexagesimal (base-60) numeral system and recorded calculations on clay tablets.
Topology is a branch of mathematics that deals with the properties of space that are preserved under continuous transformations. Topos theory, developed in the 1960s, represents a significant advancement in mathematical logic and category theory, providing a generalized framework for understanding notions in set theory, logic, and topology through the lens of category theory.
Jyā, koti-jyā, and utkrama-jyā are terms from classical Indian mathematics and astronomy, particularly in the context of trigonometry and spherical geometry. 1. **Jyā (ज्या)**: This term refers to what we would call the sine function in modern trigonometry. In classical Indian texts, "jyā" was used to describe the half-chord of an arc in a circle.
The Kraków School of Mathematics and Astrology, often referred to simply as the Kraków School, was a prominent intellectual movement in the late 15th and early 16th centuries in Poland. It mainly revolved around the work of scholars associated with the University of Kraków, known for integrating mathematical and astrological studies into their academic pursuits. Key figures associated with this school included astronomers and mathematicians who sought to apply mathematical principles to the understanding of astronomy and astrology.
Here’s a list of topics related to the history of mathematics that covers various eras, cultures, and significant developments: 1. **Ancient Mathematics** - Babylonian Mathematics - Egyptian Mathematics - Greek Mathematics (e.g., Euclid, Pythagoras, Archimedes) - Indian Mathematics (e.g., Aryabhata, Brahmagupta) - Chinese Mathematics (e.g., Liu Hui, Zhusha) 2.
Quadrature of the parabola refers to the process of finding the area under a parabolic arc. This concept was historically significant in the development of calculus and the understanding of integration. The term "quadrature" is derived from the Latin word "quadratus," meaning "square," and it essentially means finding the area (or squared measure) of a figure. The classic example involves the specific parabola described by the equation \( y = x^2 \).
The Scottish Book is a concept in set theory, particularly associated with the work of the mathematician Paul Erdős. It refers to a collaborative effort among mathematicians, primarily in the context of the "Scottish Book," where various mathematicians contribute problems that are then solved or discussed by others. The idea is that the book itself is a collection of open problems, often posed in a creative or interesting way, which encourages collaboration and communication in the mathematical community.
Like terms are terms in an algebraic expression that have the same variable components raised to the same powers. In other words, they share the exact same variable factors. For example, in the expression \(3x^2 + 5x^2 - 2x + 7\): - The terms \(3x^2\) and \(5x^2\) are like terms because they both contain the variable \(x\) raised to the power of 2.
A mathematical diagram is a visual representation used to illustrate mathematical concepts, relationships, and properties. These diagrams can take various forms, including graphs, charts, geometric figures, and flowcharts, among others. The primary purpose of mathematical diagrams is to help convey complex mathematical ideas in a more understandable and accessible way. Here are some common types of mathematical diagrams: 1. **Graphs**: Used to represent functions and relationships between variables. For instance, a Cartesian graph shows the relationship between x and y coordinates.
The Warsaw School of Mathematics refers to a group of Polish mathematicians who were prominent in the early to mid-20th century. It is primarily associated with the development of various branches of mathematics, particularly in set theory, topology, and functional analysis. The school is often linked to several key figures, including: - **Stefan Banach**: A mathematician who made significant contributions to functional analysis and is known for the Banach space concept. - **Włodzimierz P.
In mathematics, "space" is a fundamental concept that refers to a structured set of points or objects that can be analyzed and understood through various properties and relationships. Different types of spaces are defined according to the mathematical field and the properties of interest. Here are some key concepts related to mathematical spaces: 1. **Euclidean Space**: The most familiar example is Euclidean space, which consists of points in a dimensional coordinate system (e.g., 2D plane, 3D space).
"Jargonness" refers to the degree to which language, terminology, or expressions are specific to a particular field, profession, or group. It describes the extent to which jargon—specialized language or technical terms used within a specific domain—can be understood by outsiders. High jargonness indicates that a text or conversation is filled with terms that may be difficult for laypeople to understand, while low jargonness suggests that the language is more accessible and general.
Kaidā glyphs are a fictional writing system used in the fantasy series "The Broken Earth" by N.K. Jemisin. The series, which includes the novels "The Fifth Season," "The Obelisk Gate," and "The Stone Sky," explores themes of oppression, resilience, and the environment, among others. The Kaidā glyphs are part of the intricate world-building in Jemisin's books, reflecting the culture and complexity of the societies she has created.
In geometry and navigation, a "turn" typically refers to the action of changing the direction or orientation of an object, often measured in degrees or radians. A full turn corresponds to a 360-degree rotation, which brings an object back to its original position. Here are some common terms related to turns: 1. **Right Turn**: A turn of 90 degrees to the right. 2. **Left Turn**: A turn of 90 degrees to the left.
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.
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 Hermite constant is a mathematical concept in the field of number theory and geometry, particularly in relation to lattices in Euclidean spaces.
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.

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.
