Abhishek Dhar by Wikipedia Bot 0
As of my last update in October 2023, there is no widely known person or concept specifically referred to as "Abhishek Dhar." It could refer to an individual who may not be a public figure or it might also be a name common in certain regions or communities.
Abortion initiation refers to the process where a pregnancy is intentionally terminated, and "abortive initiation" specifically pertains to the methods and practices used to begin this process. There are several approaches to abortion, including: 1. **Medical Abortion**: Involves the use of medications to induce an abortion. This typically includes a combination of mifepristone (which blocks the hormone progesterone) and misoprostol (which causes the uterus to contract and expel its contents).
Verse paragraph by Wikipedia Bot 0
A verse paragraph typically refers to a section of text in poetry or song lyrics that is arranged in a structured format, often characterized by rhythm, meter, and sometimes rhyme. In contrast to prose, which flows in continuous sentences and paragraphs without specific breaks or structures, a verse paragraph is organized into lines and stanzas. In poetry, a verse paragraph may contain a theme or message and can vary in length.
"Abramowitz and Stegun" commonly refers to the book "Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables," which was edited by Milton Abramowitz and Irene A. Stegun. First published in 1964, this comprehensive reference work has been widely used in mathematics, physics, engineering, and related fields.
Covering cherub by Wikipedia Bot 0
The term "covering cherub" typically refers to a specific type of angelic being mentioned in religious texts, particularly within Judeo-Christian traditions. In the Hebrew Bible, particularly in the Book of Ezekiel, "covering cherub" describes a celestial being that is said to have a protective role.
Abrasive blasting by Wikipedia Bot 0
Abrasive blasting, also known as sandblasting or media blasting, is a surface treatment process used to clean, finish, or prepare surfaces by propelling abrasive materials at high velocities. This technique is commonly employed in various industries for applications such as removing paint, rust, or corrosion from metals, cleaning surfaces before painting or coating, and creating textured finishes.
Abrasive Flow Machining (AFM) is a precision machining process used to improve the surface finish and shape of part features that can be difficult to reach using traditional machining methods. It utilizes a flowable abrasive medium—often a viscous polymer or a viscoplastic material mixed with abrasive particles—that is forced through or across the workpiece.
Absolute electrode potential refers to the potential difference between an electrode and a reference point in a solution, often associated with the ability of an electrode to gain or lose electrons in electrochemical reactions. It is expressed in volts (V) and is used to quantify the driving force behind electrochemical processes.
ISO 31-7 by Wikipedia Bot 0
ISO 31-7 is part of the ISO 31 series of international standards that deal with physical quantities and units. Specifically, ISO 31-7 addresses the topic of "Specific quantities and units" related to the field of mechanics. It lists various mechanical quantities and their corresponding units, providing a standardized framework for measurements and ensuring consistency in scientific communication.
Absolute rotation by Wikipedia Bot 0
Absolute rotation refers to the rotation of an object in reference to a fixed point or frame of reference, rather than to another moving object. This concept can be applied in various fields including physics, engineering, and computer graphics. In physics, absolute rotation may refer to the orientation of an object in space with respect to a set of fixed axes, which are typically considered as not changing over time.
Luminiferous aether by Ciro Santilli 37 Updated +Created
Can you just imagine what if luminiferous aether was one single fixed rigid body? This is apparently what Maxwell believed, Subtle is the Lord by Abraham Pais (1982) page 111 quoting his entry to Encyclopedia Britannica:
There can be no doubt that the interplanetary and interstellar spaces are not empty but are occupied by a material substance or body, which is certainly the largest, and probably the most uniform, body of which we have any knowledge.
Then it would provide a natural space coordinate for the entire universe!
Apparently Einstein was the first to completely say: let's just screw this aether thing completely then, it's getting too complicated, and we don't really need it. As Wikipedia puts it well, in very unencyclopedic tone[ref]: Aether fell to Occam's razor.
AbsoluteTelnet by Wikipedia Bot 0
AbsoluteTelnet is a terminal emulation software application designed for Windows operating systems. It allows users to connect to various types of network devices and servers using protocols such as Telnet, SSH (Secure Shell), and more. The software provides an interface for users to interact with remote systems, making it easier to manage servers, routers, switches, and other network devices from a distance.
Dirac equation by Wikipedia Bot 0
The Dirac equation is a fundamental equation in quantum mechanics and quantum field theory that describes the behavior of fermions, such as electrons and quarks, that have spin-½. It was formulated by the British physicist Paul Dirac in 1928 as a way to reconcile the principles of quantum mechanics with special relativity. The equation incorporates both the wave-like nature of matter and the relativistic effects of high velocities.
An abstract differential equation is a mathematical equation that describes the relationship between a function and its derivatives but is expressed in a more generalized, often functional setting rather than in the traditional form of ordinary or partial differential equations. Abstract differential equations typically arise in contexts such as functional analysis, where the functions involved may take values in infinite-dimensional spaces, such as Banach or Hilbert spaces.
Plücker embedding is a mathematical construction that embeds a projective space into a higher-dimensional projective space. Specifically, it is most commonly associated with the embedding of the projective space \( \mathbb{P}^n \) into \( \mathbb{P}^{\binom{n+1}{2} - 1} \) using the concept of the lines in \( \mathbb{P}^n \).
Abundant number by Wikipedia Bot 0
An **abundant number** is a positive integer for which the sum of its proper divisors (the positive divisors excluding the number itself) is greater than the number itself.
The Abuse Reporting Format (ARF) is a structured format used primarily for reporting email abuse, such as spam, phishing, or other malicious activities. The goal of ARF is to provide a standardized way for organizations and individuals to report and share information about abuse instances to relevant parties, such as ISPs, email service providers, or law enforcement.

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.
