Vernon Estes does not appear to be a widely recognized figure or term as of my last knowledge update in October 2021. It's possible that he could be a private individual or a lesser-known figure in a specific context, such as local news, community events, or specialized fields. If there have been significant developments or news related to this name after that date, I may not be aware of them.
An automorphic number is a number whose square ends with the same digits as the number itself. In other words, if \( n \) is an automorphic number, then when you compute \( n^2 \), the last digits of \( n^2 \) will be the same as \( n \). For example: - The number 5 is automorphic because \( 5^2 = 25 \), and the last digit (5) matches the original number.
Barrett reduction is an algorithm used in the field of modular arithmetic, particularly for efficiently reducing large integers modulo a smaller integer. It is especially useful in cryptography and in computations involving large numbers where performance is critical. The Barrett reduction method is designed to avoid the expensive division operation typically associated with modular reduction. Instead of performing a direct division, it leverages precomputed values to carry out the reduction more efficiently. ### Basic Steps of Barrett Reduction 1.
"Canon arithmeticus" is a term that refers to a work by the mathematician John Napier, published in 1614. The full title in Latin is "Mirifici Logarithmorum Canonis Descriptio." This work introduced and laid the groundwork for the concept of logarithms, which are critical in mathematics, particularly for simplifying calculations involving multiplication and division.
The Kronecker symbol, denoted as \(\left(\frac{a}{n}\right)\), is a generalization of the Legendre symbol used in number theory. It is defined for any integer \(a\) and any positive integer \(n\) that can be expressed as a product of prime powers. The Kronecker symbol extends the properties of the Legendre symbol to include not just odd prime moduli, but also powers of 2 and arbitrary positive integers.
Cipolla's algorithm is a method used for efficiently computing square roots in finite fields, specifically quadratic residues, which is particularly useful in the context of cryptographic applications and certain areas of number theory. It is named after the mathematician Giovanni Cipolla.
Congruence of squares is a concept in number theory that deals with whether two numbers can be expressed as squares mod some integer. Specifically, it investigates under what conditions a quadratic residue (a number that is congruent to a perfect square modulo \( n \)) can be expressed as the square of another number modulo \( n \).
Cubic reciprocity is a concept in number theory similar to quadratic reciprocity, but it deals specifically with cubic residues and their properties. While quadratic reciprocity provides a criterion for determining whether a given integer is a quadratic residue modulo a prime, cubic reciprocity focuses on the behavior of cubic residues.
Euler's theorem is a fundamental statement in number theory that relates to modular arithmetic. It is particularly useful for working with integers and their properties under modular exponentiation. The theorem states that if \( a \) and \( n \) are coprime (i.e.
A catenane is a type of molecular structure consisting of two or more interlocked rings, similar to links in a chain. These ring-shaped molecules are connected mechanically rather than covalently, meaning that the rings won't dissociate easily without breaking chemical bonds. Catenanes are a subclass of complex molecules in the field of supramolecular chemistry and have garnered interest for their unique properties and potential applications.

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.
