The Friis transmission equation is a fundamental formula in wireless communications that describes the power received by an antenna under free space conditions. It relates the transmitted power, gain of the transmitting and receiving antennas, the distance between them, and the wavelength of the transmitted signal.
There are several fictional characters across various media who possess nuclear or radiation-related abilities. Here are some notable examples: 1. **The Hulk (Marvel Comics)** - Bruce Banner transforms into the Hulk after exposure to gamma radiation, granting him incredible strength and durability.

"Star Fairies" could refer to different things depending on the context, as it isn't a specific or well-known term with a single definition. Here are a few possibilities: 1. **Children's Media or Toys**: "Star Fairies" might refer to a line of toys, a book series, or animated shows aimed at children, likely involving fairy characters with star-themed elements.

Field trace can refer to different concepts depending on the context, so I'll outline a few possible interpretations: 1. **General Definition**: In a broad sense, a field trace could refer to a record or representation of observations or data collected from a specific field or area of study. This could be used in various disciplines, such as ecology, geography, or even data science.
In the context of Wikipedia and related projects, a "stub" refers to an article that is incomplete and does not provide enough information on a topic. A "statistical mechanics stub" would be a short or poorly developed article about statistical mechanics, which is a branch of physics that uses statistical methods to describe the behavior of systems composed of a large number of particles. Statistical mechanics bridges the gap between macroscopic and microscopic physics, allowing us to derive thermodynamic properties from the statistical behavior of particles.
The term "stability spectrum" can refer to different concepts depending on the context, such as in mathematics, engineering, or physics. Generally, it relates to examining the stability of a system or model, often through spectral analysis. 1. **In Mathematics and Control Theory**: The stability spectrum often relates to the eigenvalues of a system's matrix. The positions of these eigenvalues in the complex plane can indicate whether a system is stable, unstable, or marginally stable.
Sonic characteristics of marine species refer to the various ways in which marine organisms produce, perceive, and use sound in their underwater environments. Sound plays a crucial role in the lives of many marine animals, serving various functions such as communication, navigation, predator avoidance, and foraging. Here are some key sonic characteristics of marine species: 1. **Bioacoustics**: Many marine animals produce sounds as part of their communication.
The Centre for Nanosciences and Nanotechnologies (C2N) is typically a research institution focused on the study and application of nanoscience and nanotechnology. These centers are dedicated to advancing knowledge and innovation in areas involving materials at the nanoscale (typically 1 to 100 nanometers) and exploring their unique physical, chemical, and biological properties.
The SOTA Mapping Project refers to the "Summits on the Air" (SOTA) program, which is a popular amateur radio activity that encourages hams (amateur radio operators) to take their equipment to mountain summits and operate from these elevated locations. The SOTA Mapping Project specifically focuses on creating detailed maps and resources to assist participants in locating and reporting their activations from various summits.

Songs from the Deep South" is a compilation album that showcases a variety of soul and R&B tracks from artists associated with the Deep South musical traditions, particularly highlighting the rich cultural heritage of Southern music. The album features a range of artists, both classic and contemporary, and it aims to capture the essence and depth of the soulful sounds that have emerged from this region of the United States.
The Centre for Secure Information Technologies (CSIT) is a research organization based at Queen's University Belfast in Northern Ireland. Established in 2009, CSIT focuses on cybersecurity and related areas, aiming to advance knowledge and technology in the field of secure information systems. The center conducts cutting-edge research, fostering collaboration between academia, industry, and government to address the challenges associated with cybersecurity, data protection, and secure communications.
"Soul" is the title of an album by British singer-songwriter Seal, released in 2008. The album is a collection of soul music covers, showcasing Seal's distinctive voice and style. It includes renditions of classic soul songs, paying homage to the genre and its influential artists.
Source reduction refers to practices and strategies aimed at minimizing waste production before it is created. This approach focuses on reducing the amount of hazardous substances and materials at the source, rather than managing waste after it has been generated. Source reduction can be implemented at various levels, including households, businesses, and industries, and can include various techniques such as: 1. **Product Redesign:** Creating products that are simpler, use fewer materials, or utilize less harmful substances.
The Sousselier graph is a specific type of graph used in the study of graph theory. It is particularly noteworthy due to its unique properties, including its vertex and edge structure. The Sousselier graph is constructed from a specific configuration of vertices and edges, and it is often studied within the context of connectivity, colorability, and other combinatorial properties.
The term "stratosphere" can refer to different contexts, but it is most commonly known in two primary domains: atmospheric science and technology. 1. **Atmospheric Science**: In meteorology, the stratosphere is the second layer of Earth's atmosphere, situated above the troposphere and below the mesosphere. It extends from about 10 to 50 kilometers (6 to 31 miles) above sea level.
Stable homotopy theory is a field in algebraic topology that studies the properties of spaces and spectra that remain invariant under suspensions (or shifts). It arises from the observation that the homotopy groups of spheres, which are foundational objects in topology, exhibit a highly structured and rich behavior when examined in a stable context.
"The Hit Parade" is an album by Tak Matsumoto, a prominent Japanese guitarist and songwriter, best known as a member of the rock band B'z. Released in 2021, the album features a compilation of some of his most popular instrumental tracks and showcases his exceptional guitar skills.

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.
