Total external reflection is a phenomenon that occurs when a wave, such as light, travels from a medium with a higher refractive index to a medium with a lower refractive index and strikes the boundary at an angle greater than a certain critical angle. This angle is specific to the materials involved and can be calculated using Snell's law, which relates the angles and indices of refraction of the two media.
Fourier algebra is a concept that arises in the context of harmonic analysis and the study of topological groups. It is particularly important in the theory of locally compact groups and their representations.

These applications can be used for transcribing meetings, interviews, and other spoken content. 2. **Transcription Services**: Professional services that provide manual transcription of audio or video content into text, usually performed by human transcribers.
A Transfer Function Matrix (TFM) is a mathematical representation used in control theory and systems engineering to describe the relationship between the input and output of multi-input multi-output (MIMO) systems. It extends the concept of a transfer function, which is used for single-input single-output (SISO) systems. ### Key Features of Transfer Function Matrix: 1. **MIMO Systems**: The transfer function matrix is particularly useful for systems that have multiple inputs and multiple outputs.
The Anonymous Veto Network (AVN) typically refers to a system or framework that enables participants to express their dissent or disapproval towards specific actions, proposals, or decisions without revealing their identities. The concept is often rooted in principles of privacy and anonymity, ensuring that individual opinions can be communicated securely and freely, thereby promoting open dialogue and preventing retaliation or undue influence. While the specifics can vary based on context (e.g.
The number 103 is a natural number that comes after 102 and before 104. It is classified as a prime number, meaning it is only divisible by 1 and itself. In the decimal system, it has three digits and is often used in various mathematical contexts. Additionally, 103 can represent quantities, measurements, and more in everyday situations. In terms of its properties: - It is an odd number. - It is a prime number.
The number 114 is an integer that follows 113 and precedes 115. Here are some interesting mathematical and cultural facts about the number 114: 1. **Mathematical Properties**: - 114 is an even number. - It can be expressed as a sum of two squares: \(114 = 7^2 + 7^2\).
As of my last knowledge update in October 2021, there is no widely known figure or concept named "Francesco Ventretti." It's possible that he could be a private individual or a relatively lesser-known public figure who has come into prominence since then.
Transmitter Location Systems (TLS) are technologies used to determine the location of a radio frequency transmitter. These systems are commonly used in various fields, including telecommunications, broadcasting, emergency response, and military applications. ### Key Functions of Transmitter Location Systems: 1. **Signal Detection**: TLS typically use radio receivers that can detect the signals emitted by transmitters. By analyzing these signals, the system can gather information about the transmitter's characteristics.
Christopher Strachey was a British computer scientist and a pioneer in the field of artificial intelligence. He is best known for his work in the development of early computer programs that could play games, particularly his contributions to game playing and programming languages. One of his notable achievements was creating the first successful automation of a computer-based game, which was a checkers program written in the 1950s. Strachey's work laid an important foundation for future advancements in artificial intelligence and computer programming.
The Friedmann–Einstein universe refers to a cosmological model that describes a homogeneous and isotropic universe. It is based on solutions to Einstein's field equations of general relativity, which relate the geometry of spacetime to the energy and momentum of matter within it. The Friedmann solutions were first derived by Alexander Friedmann in the 1920s and later incorporated into the framework of general relativity by Albert Einstein.
The Internet in the United Kingdom refers to the network of interconnected digital technologies and services that allow individuals, businesses, and organizations to communicate, access information, and engage with various online platforms.

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.
