In large deviations theory, the Contraction Principle is a fundamental result that provides insights into the asymptotic behavior of probability measures associated with stochastic processes. Large deviations theory focuses on understanding the probabilities of rare events and how these probabilities behave in limit scenarios, particularly when considering independent and identically distributed (i.i.d.) random variables or other stochastic systems.
Big O notation by Wikipedia Bot 0
Big O notation is a mathematical concept used to describe the performance or complexity of an algorithm in terms of time or space requirements as the input size grows. It provides a high-level understanding of how the runtime or space requirements of an algorithm scale with increasing input sizes, allowing for a general comparison between different algorithms. In Big O notation, we express the upper bound of an algorithm's growth rate, ignoring constant factors and lower-order terms.

Ferranti MRT by Wikipedia Bot 0
Ferranti MRT is a type of digital signal processing system primarily used for the measurement and analysis of electrical signals and parameters. It is particularly popular in the field of power quality assessment, research, and various types of electrical testing. The MRT stands for "Multi-Range Transducer," indicating its capability to handle and analyze a range of electrical measurements, allowing for detailed characterization of power systems.
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.

Activation energy asymptotics often refers to the mathematical and physical considerations of how activation energy affects the rates of chemical reactions, particularly in systems where the processes can be analyzed asymptotically. In chemistry and physics, activation energy is the minimum energy that reactants must have for a reaction to take place.
Tauberian theorems are a set of results in mathematical analysis, particularly in the field of summability and asymptotic analysis. They provide conditions under which certain types of series or transforms can be inferred from the behavior of their generating functions or sequences. The general idea is to connect the asymptotic behavior of a sequence or a series with conditions imposed on its transform, such as the Laplace transform or the Dirichlet series.
The magnetic quantum number, often denoted as \( m_l \), is one of the four quantum numbers used to describe the unique quantum state of an electron in an atom. It primarily relates to the orientation of the orbital that an electron occupies in a magnetic field.
Rainbow gravity is a theoretical framework in the field of quantum gravity that suggests the structure of spacetime may depend on the energy of the observer, leading to a "rainbow" of different gravitational effects based on the energy levels of particles. This theory is primarily explored in the context of various models that seek to unify general relativity and quantum mechanics. The fundamental idea is that the laws of physics, particularly those related to gravity, could vary depending on the energy at which an observer measures them.

Schilder's theorem is a fundamental result in probability theory, particularly in the area of large deviations. It provides an asymptotic estimate for the probabilities of large deviations for sequences of random variables. Specifically, it deals with the behavior of the empirical measures of random walks. More formally, Schilder's theorem states that for a sequence of independent and identically distributed random variables, the probability that the empirical measure deviates significantly from its expected value decays exponentially as the number of samples increases.
The Papaloizou–Pringle instability is a type of instability that occurs in rotating disks of gas and is particularly relevant to astrophysical contexts, such as accretion disks around black holes and other compact objects. The instability is named after the astrophysicists Alex Papaloizou and John Pringle, who described it in the context of astrophysical disks in the 1980s.

Pinned article: ourbigbook/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.
