A European windstorm refers to a weather phenomenon characterized by strong winds, often accompanied by heavy rain, thunderstorms, and sometimes snowfall, that affects parts of Europe, particularly during the autumn and winter months. These storms can develop as a result of low-pressure systems forming over the North Atlantic Ocean and moving towards Europe.
Bridgefy is a communication application designed to enable users to send and receive messages without requiring an internet connection or mobile data. It uses Bluetooth and mesh networking technology to facilitate communication directly between devices in close proximity. This makes it particularly useful in situations where cellular networks may be unreliable or unavailable, such as during protests, natural disasters, or in remote areas. Bridgefy allows users to send text messages, photos, and other types of content to one another even when they are not connected to the internet.
The Great Storm of 1703 was one of the most severe storms ever recorded in England. It occurred from November 26 to November 27, 1703, and was notable for its ferocity and the extensive damage it caused. The storm is estimated to have reached hurricane-force winds, with gusts exceeding 100 miles per hour (160 km/h), and it primarily affected southern England.
As of my last knowledge update in October 2023, Storm Athina refers to a weather event or storm system that occurred in late 2023. It may have affected certain regions with heavy rainfall, strong winds, and other severe weather conditions.
Storm Desmond was a powerful and severe winter storm that affected parts of the United Kingdom and Ireland in early December 2015. It was notable for causing widespread flooding, particularly in northern England, including areas like Cumbria and Lancashire. The storm brought heavy rainfall, high winds, and severe weather conditions, leading to significant disruptions, including road closures, transport delays, and power outages.
Storm Emma was a weather event that affected parts of Europe, particularly the United Kingdom and Ireland, in early March 2018. It was caused by a combination of a cold Arctic air mass and an intense low-pressure system that brought significant snowfall and extremely cold temperatures. The storm resulted in heavy snowfall, blizzard conditions, and extreme weather, leading to widespread travel disruptions, school closures, and power outages. In some areas, drifts of snow reached several meters.
The Brocard triangle is a concept in triangle geometry related to the circumcircle and the Brocard points of a given triangle. To understand the Brocard triangle, we first need to define the Brocard points, often denoted as \( \Omega_1 \) and \( \Omega_2 \).
Circle packing in an isosceles right triangle refers to the arrangement of circles (typically of equal size) within the confines of an isosceles right triangle such that the circles do not overlap and are completely contained within the triangle. In an isosceles right triangle, the two equal sides form a right angle, and the circles can be arranged in various patterns based on geometric principles and packing density.
In anatomy, the transversal plane (also known as the transverse plane or horizontal plane) is an imaginary plane that divides the body into superior (upper) and inferior (lower) parts. This plane runs horizontally across the body, perpendicular to both the sagittal plane (which divides the body into left and right) and the coronal (frontal) plane (which divides the body into anterior (front) and posterior (back) sections).
As of my last knowledge update in October 2023, there isn't widely recognized information or significant public figures known specifically as "Ansar Pervaiz." It's possible that he could be a private individual, a local figure, or have emerged in a specific context or region that is not widely reported or known globally.
Mohammed Naseer Khan may refer to several people, as it is a common name in certain regions. To provide a more accurate answer, additional context or specific details about the person you are inquiring about would be helpful.
Mazhar Mahmood Qurashi is not widely known in popular media or literature, and there may not be prominent figures by that exact name. It's possible that he is a private individual or a lesser-known figure in a specific field. If you have more context about his background, achievements, or the specific area (e.g.
Muhammad Hafeez Qureshi may refer to several individuals, as it's a common name in South Asia, particularly in Pakistan. If you're asking about a specific person, such as a politician, scholar, or other public figure, more context would help identify him. One notable figure by that name is Muhammad Hafeez Qureshi, a Pakistani politician known for being a member of the National Assembly of Pakistan. However, without additional details, it's challenging to provide a precise description.
Mujahid Kamran is a Pakistani academic, author, and public speaker known for his work in the fields of education, philosophy, and political commentary. He has served as the Vice Chancellor of the University of the Punjab and has been involved in various initiatives related to education reform in Pakistan. Kamran has also written extensively on various topics, including history, politics, and economics, and he is associated with alternative and critical perspectives on mainstream narratives.
Nazir Ahmed is a physicist known for his contributions to the field of physics, particularly in the areas related to applied physics, condensed matter physics, and nanotechnology. His research often focuses on the theoretical and experimental aspects of physical phenomena, leading to advancements in understanding materials and their applications in technology. While detailed biographical information about Nazir Ahmed may not be widely available, he may be affiliated with academic or research institutions, where he has published scientific papers and collaborated on various projects.
A decagon is a polygon with ten sides and ten angles. In a regular decagon, all sides are equal in length and all angles are equal in measure, with each internal angle measuring 144 degrees. The sum of all internal angles in a decagon is 1,440 degrees. Decagons can be found in various fields, including architecture, design, and mathematics.
A heptagon is a polygon that has seven sides and seven angles. The term "heptagon" comes from the Greek word "hepta," meaning seven. In a heptagon, the sum of the interior angles is 900 degrees, which can be calculated using the formula \((n - 2) \times 180\), where \(n\) is the number of sides. Heptagons can be regular or irregular.
Piecewise-circular curves are geometric constructions made up of multiple segments, where each segment can be represented as a circular arc. Instead of being a single continuous circular arc, the entire curve is comprised of several arcs that are connected at specific points, forming a continuous path. Each arc in a piecewise-circular curve can have different radii, and the points at which they connect can be chosen based on various criteria, such as smoothness, angle, or specific spatial constraints.
A Gaussian period is a mathematical concept that arises in number theory, specifically in the study of algebraic integers within cyclotomic fields. In particular, a Gaussian period is associated with the Gaussian integers, which are complex numbers of the form \( a + bi \), where \( a \) and \( b \) are integers and \( i \) is the imaginary unit.
The mixtilinear incircle of a triangle is a special circle associated with a triangle, particularly in relation to its vertices and its incircle. For a given triangle \( ABC \), the mixtilinear incircle pertaining to a vertex, say \( A \), is the circle that is tangent to: 1. The incircle of triangle \( ABC \), 2. The arc \( BC \) of the circumcircle of triangle \( ABC \) that does not contain the vertex \( A \).

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.
