Henry Scheffé (1904-1977) was an American statistician known for his contributions to the field of statistics, particularly in experimental design and analysis of variance (ANOVA). He is best known for developing what is now called the Scheffé method, a statistical technique used for making multiple comparisons among group means after performing ANOVA.
Leo Breiman was a prominent statistician known for his significant contributions to the fields of statistics and machine learning. He was born on September 27, 1928, and passed away on October 5, 2005. Breiman was particularly influential in the development of algorithms and methods that have shaped modern data analysis. One of his most notable contributions is the development of the Random Forest algorithm, which is widely used for classification and regression tasks in various fields.
Melvin R. Novick is a prominent figure in the fields of psychology and psychometrics. He is well-known for his contributions to measurement theory, educational assessment, and the development of statistical models for understanding psychological constructs. Novick's work often focuses on item response theory (IRT) and other methods used in educational testing and psychological evaluation.
A tidal disruption event (TDE) occurs when a star passes too close to a supermassive black hole, resulting in the gravitational forces of the black hole tearing the star apart. This event typically happens when the star approaches within a certain critical distance known as the tidal radius. During a TDE, the intense gravitational field of the black hole can exceed the gravitational forces holding the star together, leading to the star being ripped apart.
"Rollin'" is a documentary film that delves into the world of roller skating, particularly focusing on the culture and communities surrounding the sport. The film often highlights the lives of skaters, their experiences, and the impact of roller skating on their identities. It explores themes of freedom, expression, and community, showcasing both the artistic and athletic aspects of roller skating.
A gamma-ray burst (GRB) is an extremely energetic explosion that occurs in distant galaxies, characterized by the emission of intense gamma rays. These bursts are among the most luminous events known in the universe and can release more energy in a few seconds than the Sun will emit over its entire 10-billion-year lifetime.
"Starspot" can refer to a couple of different concepts, depending on the context: 1. **Astronomy**: In the context of stars, a "starspot" is analogous to a sunspot on the Sun. Starspots are cooler, darker areas on the surface of a star caused by magnetic activity. They can affect the radiation output of the star and can be important for understanding stellar activity and behavior.
The Kalb-Ramond field is a theoretical construct in physics, specifically in the context of string theory and higher-dimensional field theories. It is a type of antisymmetric tensor field, typically denoted as \( B_{\mu\nu} \), where the indices \( \mu \) and \( \nu \) represent spacetime dimensions.
A glossary of Sudoku would typically include terms and concepts related to the game of Sudoku, which is a popular logic-based puzzle.
The term "Sudoku code" can reference a few different things depending on the context, but it generally pertains to either programming a Sudoku game or generating Sudoku puzzles algorithmically. Here's an overview of different interpretations: ### 1. **Sudoku Puzzle Representation:** A Sudoku puzzle can be represented in a programming language as a grid or matrix. For instance, a 9x9 Sudoku grid can be represented as a two-dimensional array in languages like Python, Java, or JavaScript.
The LaTeX Project Public License (LPPL) is a software license specifically created for the LaTeX typesetting system and its associated packages. It was designed to ensure that LaTeX remains free to use and distribute, while also maintaining certain standards for authors who contribute to the LaTeX ecosystem.
BaZnGa is a chemical compound composed of barium (Ba), zinc (Zn), and gallium (Ga). The specific structure and properties of BaZnGa would depend on the particular stoichiometry and crystalline form. Generally, compounds that consist of multiple metals can exhibit interesting physical, chemical, and electronic properties, potentially making them useful in various applications such as electronics, catalysis, or materials science.
The Denjoy-Wolff theorem is a result in complex analysis, particularly in the field of iterated function systems and the study of holomorphic functions. It characterizes the dynamics of holomorphic self-maps of the unit disk, specifically focusing on the behavior of iterates of such functions.
The Whitney extension theorem is a fundamental result in the field of analysis and differential geometry, concerning the extension of functions defined on a subset of a Euclidean space to the entire space while preserving certain properties.
Israel by Ciro Santilli 40 Updated 2025-07-16
What they are doing to the Palestinians is a tremendous injustice. Either give them citizenship, or give them a country.
The fact that the United States supports this is an incurable black mark in their moral standing that will not be forgotten for a very long time.
Extensive quantities are properties of a system that depend on the amount of material or the size of the system. In other words, they are additive properties that change when the system is divided into smaller parts. Extensive quantities are proportional to the size or extent of the system. Common examples of extensive quantities include: 1. **Mass** - The total amount of matter in a system. 2. **Volume** - The amount of three-dimensional space occupied by the system.
A lot of skateboarders hand out there, and it was where Ciro Santilli used to practice Cirodance.
United Kingdom by Ciro Santilli 40 Updated 2025-07-16
The United Kingdom is one big field.
Everything is extremely uniform and fully controlled by humans. Maybe this is partially due to it being an island with extensive flood plains. Loots of white mana floating around there.
Some impressively sounding natural parks look more like cute countryside that is slightly hillier than the surrounding countryside.
This uniformity does however make it quite comfortable for its Hobbit inhabitants.
It also means that whenever slightly out of the ordinary happens, e.g., a bit of slightly heavier rain, everything floods. In some way however, the Brits are very pragmatic, and as long as the flood is not too bad, they just let it be, it might be cheaper.

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
