A minimal counterexample is a specific type of counterexample that demonstrates that a certain statement or conjecture is false while also satisfying an additional criterion of minimality. In mathematical terms, a counterexample is an instance that disproves a given statement (for example, a theorem or conjecture).
Miroslav Fiedler is not widely recognized in popular culture or prominent historical contexts. However, it appears he is known for his involvement in specific fields or regions, particularly in relation to literature, science, or academia. Without more specific context, it's difficult to provide a detailed answer.
Model horses are scale replicas of real horses, typically made from materials such as plastic, resin, or ceramics. They are used primarily for collecting, display, and play. Model horses come in various sizes and styles, often replicating specific horse breeds, colors, and poses. There are several aspects of model horses: 1. **Collecting**: Many enthusiasts collect model horses as a hobby. They may focus on specific breeds, brands, or variations, often participating in shows and competitions.
Modular curves are fundamental objects in number theory and algebraic geometry that arise in the study of modular forms and elliptic curves. They provide a geometric way to understand properties of these mathematical structures. ### Definition A modular curve, often denoted as \( X(N) \) for some integer \( N \), parametrizes isomorphism classes of elliptic curves together with additional level structure.
The moduli of algebraic curves is a concept in algebraic geometry that deals with the classification of algebraic curves up to some notion of equivalence, typically isomorphism or more generally, a family of curves. The goal is to understand how many distinct algebraic curves exist, as well as the ways in which they can vary. ### Key Concepts 1.
In mathematics, particularly in physics and engineering, the term "moment" generally refers to a quantitative measure of the effect of a force applied at a distance from a point or axis. The concept is used in various contexts, and the most common types of moments include: 1. **Moment of Force (Torque)**: This is a measure of the tendency of a force to rotate an object about a specific point or axis.
Monika Schleier-Smith is an accomplished physicist known for her work in the fields of atomic, molecular, and optical (AMO) physics, as well as quantum information science. She has made significant contributions to the study of many-body quantum systems and the manipulation of cold atoms. Schleier-Smith has also been involved in research related to quantum optics and entangled states. She is recognized for her innovative approaches and experimental techniques that advance our understanding of quantum mechanics and its applications.
A tube tester is a device used to test the functionality and performance of vacuum tubes, which were commonly used in electronics, especially in audio amplifiers, radios, and other equipment, before the advent of solid-state devices like transistors. Tube testers assess the condition of tubes by measuring various electrical parameters such as filament continuity, emission (the ability of the tube to emit electrons), mutual conductance (the ability to amplify a signal), and more.
The Mostowski model is an important construction in set theory, particularly in the context of model theory and the study of set-theoretic structures. It essentially demonstrates how certain properties of mathematical structures can be realized through specific kinds of models. The Mostowski model is typically discussed in the framework of Zermelo-Fraenkel set theory (ZF), specifically focusing on the axiom of choice.
Muhammad Baqir Yazdi, also referred to as Muhammad Baqir al-Majlisi, was a prominent Shia Islamic scholar, theologian, and jurist who lived in the 17th century (1627-1699). He was a significant figure in the development of Shia theology and the compilation of hadith (sayings and actions of the Prophet Muhammad and the Imams in Shia Islam).
Murray R. Spiegel is an author and educator known primarily for his contributions to mathematics, particularly in the field of applied mathematics and statistics. He is most notable for his books that are widely used in academic settings, especially "Schaum's Outline of Advanced Mathematics for Engineers and Scientists" and other titles in the Schaum's Outline series. These books are popular for their clear explanations, practical examples, and problem-solving approaches, making complex topics more accessible to students and working professionals.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
