A Nuclear Electromagnetic Pulse (NEMP) is a burst of electromagnetic energy generated by a nuclear explosion. This phenomenon occurs due to the interaction of gamma rays emitted during the explosion with the Earth's atmosphere and magnetic field, leading to the production of high-energy electrons. These electrons, in turn, create a powerful electromagnetic pulse. NEMP is characterized by its ability to disrupt or damage electrical and electronic systems over a wide area.
"Radioflash" can refer to different concepts depending on the context. One common reference is to a media or entertainment project, but it could also relate to technology or communication methods. Without additional context, it's challenging to provide a specific answer. 1. **Entertainment**: "Radioflash" could be a title for a film, show, or song. 2. **Technology**: It may refer to a feature or technology related to radio communications or broadcasting.
Visual MIMO (Multiple Input Multiple Output) is a technology that extends the principles of traditional MIMO systems, which are commonly used in wireless communications, to the realm of visual data transmission and processing. While traditional MIMO leverages multiple antennas to transmit and receive radio signals, Visual MIMO involves the use of multiple cameras or visual sensors to capture, process, and transmit visual information.
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.

Kelihos is a well-known botnet that has been used primarily for sending spam emails, distributing malware, and conducting cybercriminal activities such as data theft and credential harvesting. First identified around 2010, it has evolved through various iterations, with the most infamous versions being Kelihos 1.0 and Kelihos 2.0.
Kainosymmetry is not a widely recognized term in mainstream academic or scientific literature. However, breaking down the word can give some insight into its possible meanings. The prefix "kaino-" is derived from the Greek word "kainos," which means "new" or "recent." The suffix "symmetry" typically pertains to balance or proportion in various contexts, such as in mathematics, physics, or art.
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.
The Volume Conjecture is a mathematical hypothesis related to the field of knot theory and hyperbolic geometry. It proposes a deep connection between the volumes of hyperbolic 3-manifolds and quantum invariants of knots, specifically those derived from a quantum invariant known as the Kauffman polynomial or the colored Jones polynomial.
Planar algebra is a mathematical structure that arises in the study of operator algebras and three-dimensional topology. It was introduced by Vaughan Jones in the context of his work on knot theory and nontrivial solutions to the Jones polynomial. Planar algebras provide a framework for understanding the relationship between combinatorial structures, algebraic objects, and topological phenomena. In essence, a planar algebra consists of a collection of vector spaces parameterized by non-negative integers, typically with a specified multiplication operation.
Stochastic geometry is a branch of mathematics that deals with the study of random spatial structures and patterns. It combines elements from geometry, probability theory, and statistics to analyze and understand phenomena where randomness plays a key role in the geometric configuration of objects. Key concepts and areas of interest in stochastic geometry include: 1. **Random Sets**: Studying collections of points or other geometric objects that are distributed according to some random process.
Isostructural refers to a situation where two or more different substances or compounds crystallize in the same structural arrangement or lattice type, despite potentially differing in their chemical composition. This means that the overall geometric arrangement of the atoms or molecules in the crystal is similar, and they have the same symmetry properties, even though the individual components may be different. Isostructural compounds often exhibit similar physical properties, such as thermal expansion, crystal packing, and sometimes even similar electronic properties.
Tetrahedral molecular geometry is a three-dimensional arrangement of atoms in which a central atom is bonded to four other atoms positioned at the corners of a tetrahedron. This geometry is characterized by bond angles of approximately 109.5 degrees. The tetrahedral shape results from the repulsion between electron pairs around the central atom, which is often carbon or a similar atom with four bonding sites.
Alexey Alexandrov could refer to multiple individuals, as it is a relatively common name. Without more context, it's difficult to pinpoint exactly which Alexey Alexandrov you are referring to. For instance, it could be a reference to: 1. **A scientist or academic**: There may be notable individuals with that name in fields such as physics, mathematics, or other areas of research.
Bengt Strömgren (1908–1987) was a Swedish astronomer known for his contributions to the field of astrophysics. He is particularly noted for his work on star classification and his role in the development of stellar evolution theory. Strömgren is famous for the introduction of the Strömgren photometric system, which is a set of filters used to measure the brightness of stars at specific wavelengths.
Ebru Bozdağ may refer to a specific individual, but as of my last update in October 2023, there is limited information publicly available about someone by that name. It's possible that she could be a private individual or a less widely known public figure.

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.

  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.
