Hekat by Wikipedia Bot 0
Hekat is a figure from ancient mythology, primarily associated with Greek religion. Often referred to as Hecate, she is known as the goddess of magic, witchcraft, the moon, and a guardian of the underworld. Hecate is frequently depicted in art and literature as a woman with three forms or faces, symbolizing her connection to the triple aspects of the moon—waxing, full, and waning—as well as her role as a guide and guardian at crossroads.
Hydraulic seal by Wikipedia Bot 0
A hydraulic seal is a device used to prevent the leakage of hydraulic fluids in hydraulic systems. It is critical for maintaining pressure within hydraulic cylinders, pumps, and other components that operate under high pressure. Hydraulic seals help ensure that the fluid does not escape between stationary and moving parts, thus preventing contamination, improving efficiency, and minimizing wear. There are various types of hydraulic seals, including: 1. **O-Rings**: These are circular cross-section seals that compress to form a seal in a groove.
The Hellenic Mathematical Society (HMS) is a professional organization in Greece that aims to promote mathematical research, education, and communication. Established in 1910, the HMS serves as a platform for mathematicians in Greece and abroad to collaborate, share knowledge, and advance the field of mathematics. Key activities of the Hellenic Mathematical Society typically include: 1. **Organizing Conferences:** The society organizes national and international conferences, workshops, and seminars to facilitate discussions on various mathematical topics.
The history of computing is a fascinating journey that chronicles the evolution of computing machinery, algorithms, and the general concept of computation. Here’s an overview of key developments throughout this history: ### Ancient to Medieval Periods - **Abacus (circa 500 BC)**: The earliest known computing device, used for basic arithmetic calculations. - **Antikythera Mechanism (circa 150 BC)**: An ancient Greek analog computer used to predict astronomical positions and eclipses.
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.
Modular decomposition is a concept primarily used in graph theory and computer science, particularly in the study of algorithms and structures related to graphs. It involves breaking down a graph into its simpler, modular components or modules based on the relationships between its vertices. ### Key Concepts: 1. **Module**: In a graph, a module (or a strongly connected component) is a subset of vertices such that every vertex in this subset is equally connected to all the other vertices in the subset.
The history of manifolds and varieties is a rich and evolving narrative within mathematics, particularly in the fields of geometry, topology, and algebraic geometry. Here’s an overview of their development: ### Early Concepts 1. **Geometry and Curves (Ancient to Renaissance)**: Early thinkers like Euclid focused on geometric shapes, while the study of curves began to take shape during the Renaissance with the work of mathematicians like Descartes and Fermat.
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.
The Hobbes-Wallis controversy refers to a philosophical and scientific debate from the 17th century that centered around the nature of mathematical truths and the existence of absolute space and time. This controversy primarily involved Thomas Hobbes, an English philosopher, and John Wallis, an English mathematician and theologian. The disagreement arose over several issues related to geometry and the nature of mathematical proofs. Hobbes was critical of the geometric methods employed by Wallis and other mathematicians of the time.
Iatromathematicians, or iatromathematics, refers to a historical approach where mathematics was applied to medicine. The term combines "iatro," meaning physician or medicine, with "mathematics."

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.
