Monika Ritsch-Marte is a prominent figure in the field of biomedical optics and photonics, known for her contributions to research and development in areas such as optical coherence tomography and medical imaging. She is often involved in academic circles, contributing to scientific literature and education.
A directed graph (or digraph) is a type of graph in which the edges have a specific direction. This means that each edge connects an ordered pair of vertices (or nodes), indicating a one-way relationship between them. In more formal terms, if there is a directed edge from vertex \( A \) to vertex \( B \), it is often represented as \( A \rightarrow B \).
A rooted graph is a type of graph in which one particular vertex is designated as the "root." This root serves as a reference point for various operations and representations associated with the graph. Rooted graphs are commonly used in various areas of computer science and mathematics, especially in the context of tree structures, where the graph is typically acyclic and hierarchical. Key characteristics of a rooted graph include: 1. **Root Vertex**: One vertex is distinguished as the root.
"Opticks" is a significant work by Sir Isaac Newton, published in 1704. The full title is "Opticks: or, A Treatise of the Reflections, Refractions, Inflections and Colours of Light." In this work, Newton explored the nature of light and color, proposing that white light is composed of a spectrum of colors, which can be separated by prisms. He also conducted experiments related to the behavior of light, including its reflection and refraction.
The Forbidden Subgraph Problem is a concept from graph theory, related to understanding the structure of graphs by identifying certain subgraphs that are "forbidden" or not allowed within a graph. More formally, the problem can be described as follows: Given a graph \( G \) and a set of graphs \( H \), the Forbidden Subgraph Problem asks whether \( G \) contains any subgraph that is isomorphic to any of the graphs in the set \( H \).
The Erdős–Ko–Rado theorem is a fundamental result in combinatorial set theory, particularly in the area concerning intersecting families of sets. It was first proved by Paul Erdős, Chao Ko, and Ronald Rado in 1961. ### Statement of the Theorem: For a finite set \( X \) with \( n \) elements, let \( k \) be a positive integer such that \( k \leq \frac{n}{2} \).
A Wilson prime is a special type of prime number that satisfies a specific mathematical property related to Wilson's theorem. Wilson's theorem states that a natural number \( p > 1 \) is a prime number if and only if: \[ (p - 1)! \equiv -1 \ (\text{mod} \ p) \] For a number to be classified as a Wilson prime, it must not only be prime but also satisfy the condition: \[ (p - 1)!
Haiku is an open-source operating system that is intended to be a modern reimplementation of the Be Operating System (BeOS). The project's history can be traced back to the early 2000s, shortly after BeOS ceased commercial development. ### Key Points in the History of Haiku: 1. **Origins (2001)**: The Haiku project began as an initiative to recreate BeOS after the original developers stopped maintaining it.
The Hypergeometric distribution is a probability distribution that describes the likelihood of a certain number of successes in a sequence of draws from a finite population without replacement. It is particularly useful in scenarios where you are interested in sampling a small number of items from a larger group without putting them back into the group after each draw. ### Parameters of the Hypergeometric Distribution The Hypergeometric distribution is defined by the following parameters: 1. **N**: The population size (the total number of items).
The hypergeometric function is a special function represented by a power series that generalizes the geometric series and many other functions.
Lozanić's triangle is a geometric concept associated with certain properties of a triangle in relation to its circumcircle and incircle. Specifically, it involves a triangle's vertices, the points of tangency of the incircle, and several notable points related to the triangle's configuration. The triangle focuses on the intersection points of segments that connect the vertices of the triangle to the points where the incircle touches the triangle's sides.
The Negative Hypergeometric Distribution is a discrete probability distribution that is used in scenarios where you are drawing objects from a finite population without replacement, and you are interested in the number of failures before a certain number of successes is achieved. ### Characteristics: 1. **Population Size (N)**: The total number of objects in the population. 2. **Successes in Population (K)**: The number of objects in the population that are considered "successes.
In set theory, a **universal set** is defined as the set that contains all possible elements within a particular context or discussion. It serves as a boundary for other sets being considered and encompasses all objects of interest relevant to a particular problem or situation.
Fairness criteria refer to a set of standards or principles used to evaluate and ensure equitable treatment and outcomes in various contexts, particularly in areas such as machine learning, data science, public policy, and social justice. The goal of applying fairness criteria is to mitigate bias, promote equity, and ensure that decisions and predictions are just and do not discriminate against any particular group based on characteristics such as race, gender, age, socioeconomic status, or other attributes.
The Dubins-Spanier theorems are results in the theory of stochastic processes, particularly concerning the behavior of certain classes of random walks, especially in relation to the concepts of ergodicity and recurrence. ### Key Concepts: 1. **Random Walks**: A type of stochastic process that describes a path consisting of a succession of random steps. Random walks can be one-dimensional or multidimensional and are foundational in probability theory.
Fair division among groups refers to the principles and methods used to allocate resources or assets among multiple parties in a way that is perceived as fair and equitable. This concept is particularly important in situations where resources are limited, and parties have different preferences or claims to those resources. Key aspects of fair division include: 1. **Equitability**: Ensuring that each party feels they have received a fair share relative to what others have.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
