The Boué–Dupuis formula is a result in the field of stochastic analysis, particularly in the context of large deviations. It provides a methodology for determining the asymptotic behavior of certain functionals of stochastic processes. The formula is useful in the study of complex systems and processes that exhibit stochastic behavior, such as random walks and diffusion processes.
The Bradley–Terry model is a probabilistic model used in statistics to analyze paired comparisons between items, such as in tournaments, ranking systems, or voting situations. The model is particularly useful in scenarios where the objective is to determine the relative strengths or preferences of different items based on the outcomes of pairwise contests.
Bridge disasters caused by tropical cyclones refer to structural failures or significant damage to bridges as a direct result of the extreme weather conditions associated with tropical cyclones. These storms can produce high winds, heavy rainfall, and flooding, which can compromise the integrity of bridge structures in several ways: 1. **High Winds**: The intense winds associated with tropical cyclones can physically damage bridge components, such as railings, deck surfaces, and supports.
A British Thermal Unit (BTU) is a unit of measurement used to quantify the amount of heat energy. Specifically, it represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit at a constant atmospheric pressure. BTUs are commonly used in various fields, such as heating, ventilation, air conditioning (HVAC), and energy production. For instance, HVAC systems often have ratings in BTUs to indicate their heating or cooling capacity.
Myoglobin by Ciro Santilli 40 Updated 2025-07-16
From Wikipedia:
In humans, myoglobin is only found in the bloodstream after muscle injury.
Cameco Corporation is one of the largest publicly traded uranium companies in the world, headquartered in Saskatoon, Saskatchewan, Canada. Founded in 1988, Cameco is primarily involved in the exploration, mining, and production of uranium, which is a key component used in nuclear power generation. The company operates several uranium mines and projects, primarily in Canada and the United States, and it also has interests in nuclear fuel manufacturing.
Guy Terjanian is a name that may refer to different individuals or contexts, but one notable person is an academic and author known for his work in the field of economics and political science. He has been involved in various scholarly and professional activities, including research, teaching, and writing.
Karin Erdmann is a relatively common name, and without specific context, it could refer to different individuals. One notable person with that name is a German artist and designer known for her work in fields like sculpture or installation art.
Luchezar L. Avramov is a mathematician known for his work in commutative algebra, algebraic geometry, and related fields. He has contributed to the understanding of modules over local rings and the properties of various algebraic structures.
Marie Johanna Weiss does not appear to be a widely recognized figure or concept in public knowledge based on information available up to October 2023. It's possible that there may be individuals with that name, or it could refer to something less known or more recent.
Otto Schilling is not a widely recognized term or name associated with a well-known figure, concept, or brand as of my last knowledge update in October 2023. It is possible that you are referring to a specific individual, a fictional character, a brand, or perhaps a term that has gained significance more recently.
Peter Cameron is a noted mathematician known for his contributions to various areas of mathematics, particularly in combinatorics, algebra, and graph theory. He has made significant strides in the study of permutation groups, finite geometries, and design theory. Cameron has published numerous papers and has contributed to the mathematical community through his research and teaching. In addition to his research work, Peter Cameron has held academic positions at various institutions and has been involved in mathematical education and mentorship.
Thomas Harriot (1560–1621) was an English mathematician, astronomer, and explorer, known for his contributions to various fields of science and for being one of the first to use a telescope for astronomical observations in England. He is perhaps best known for his work "A Brief and True Report of the New Found Land of Virginia," in which he documented the flora, fauna, and indigenous peoples of the region during his time as a member of an expedition to the Americas.
Concurrent estimation is a statistical or computational method used to estimate multiple parameters or quantities simultaneously rather than sequentially. This approach can be applied in various fields such as statistics, machine learning, control systems, and more. The core idea is to leverage the relationships and dependencies among the parameters being estimated to improve the accuracy and efficiency of the estimation process.
Factorization of polynomials is the process of breaking down a polynomial into a product of simpler polynomials, often called "factors." This process is similar to factoring numbers into their prime components. The goal of factorization is to express the polynomial as a product that is easier to work with or to solve equations involving the polynomial.

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
