Conditional probability distribution refers to the probability distribution of a subset of random variables given the values of other random variables. It allows us to understand how the probability of certain outcomes changes when we have additional information about other related variables. In mathematical terms, given two random variables \(X\) and \(Y\), the conditional probability distribution of \(Y\) given \(X\) is denoted as \(P(Y | X)\).
Gallium arsenide by Ciro Santilli 40 Updated 2025-07-16
This is apparently the most important III-V semiconductor, it seems to actually have some applications, see also: gallium arsenide vs silicon.
Tsuneo Tamagawa is a Japanese artist and illustrator known for his work in various creative fields, including illustration and design. His style often combines traditional Japanese aesthetics with contemporary elements. Tamagawa's work may include illustrations for books, advertisements, and other media, and he may also engage in exhibiting his artwork in galleries or art shows.
Star refinement is a concept often encountered in the context of database systems, data warehousing, and multidimensional data modeling. It refers to a specific way of organizing and optimizing data structures to facilitate efficient querying and analysis. In more detail, the concept can be discussed in the realm of the star schema, which is a type of database schema that is widely used in data warehouses.
The "Ping-Pong scheme" typically refers to a type of attack or exploitation tactic in various contexts, particularly in cybersecurity and financial fraud. However, without more specific context, it's challenging to provide a precise definition, as the term can have different meanings based on the field in which it is used.
In astronomy, "tug of war" refers to the gravitational interactions between celestial bodies, particularly in a system involving multiple massive objects, such as stars or planets. This term can describe the competition between gravitational pulls from different bodies that can affect their orbits, trajectories, or stability in a system.
A "100-year flood" is a term used in hydrology and flood management to describe a flood event that has a 1% probability of occurring in any given year. It does not mean that the flood will only happen once every hundred years; instead, it reflects the statistical likelihood of such an event occurring.
The middle ear is a part of the ear that lies between the outer ear and the inner ear. It plays a crucial role in the process of hearing. The middle ear consists of three main components: 1. **Tympanic Membrane (Eardrum)**: This thin membrane separates the outer ear from the middle ear and vibrates in response to sound waves, converting them into mechanical vibrations.
The Radio Neutrino Observatory in Greenland, commonly referred to as the Greenland Neutrino Observatory (GNO), is a proposed scientific facility designed to detect high-energy neutrinos originating from astronomical phenomena such as supernovae, gamma-ray bursts, and active galactic nuclei. The observatory aims to use the ice sheet in Greenland as a detector medium. By deploying an array of radio antennas beneath the ice, scientists can observe the faint signals produced when neutrinos interact with the ice.
Dollis Hill is an area located in the London Borough of Brent, in northwest London, England. It is primarily a residential neighborhood known for its tree-lined streets and a mix of housing types, including Victorian and Edwardian homes. One of the notable features of Dollis Hill is its proximity to Dollis Hill Park, a public park that provides green space and recreational facilities for local residents. Dollis Hill is also known for its historical significance, with connections to the Victorian era.
Asymptotic homogenization is a mathematical technique used to analyze heterogeneous media – that is, materials with varying properties at different scales. This approach is particularly useful in the study of partial differential equations (PDEs) that describe phenomena in materials with complex microstructures. The primary objective of asymptotic homogenization is to derive effective (or homogenized) equations that can describe the macroscopic behavior of such materials by averaging out the microscopic variations.
A divergent series is an infinite series that does not converge to a finite limit. In mathematical terms, a series is expressed as the sum of its terms, such as: \[ S = a_1 + a_2 + a_3 + \ldots + a_n + \ldots \] Where \( a_n \) represents the individual terms of the series. If the partial sums of this series (i.e.
Garth Paltridge is an Australian atmospheric scientist known for his work in climate science and his critical views on the prevailing consensus regarding climate change. He has contributed to the field through research, publications, and public commentary. Paltridge has been a vocal advocate for skepticism regarding certain climate change models and policies, and he often emphasizes the complexity of climate systems and the uncertainties that exist in climate projections. His views have sparked discussions and debates within the scientific community and among the public regarding climate change discourse.
Silex is a lightweight PHP micro-framework designed to simplify the development of web applications. It provides a minimal setup and essential features needed to build web applications quickly while allowing developers to add only the components they need, maintaining flexibility and performance. Some key features of Silex include: 1. **Simplicity**: It offers a straightforward way to define routes and handle requests, making it easier to build small web applications or APIs without the overhead of a full-fledged framework.
There are several types of auctions, each with its own set of rules and procedures. Here are some of the most common types: 1. **English Auction**: This is the most common auction type, where the auctioneer starts with a low price and participants bid higher amounts until no one is willing to bid further. The item is sold to the highest bidder.
Charles Alexander Shain may refer to a notable figure known for contributions in a particular field, but the name does not correspond particularly to a widely recognized historical or contemporary figure in major contexts or disciplines.
Thomas Parnell was an Australian scientist and professor known for his work in the field of physics, particularly in the study of viscoelastic materials and the long-term behavior of certain substances. He is most notably recognized for his role in the famous experiment involving pitch, demonstrating its viscous properties.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
