Hugo Hadwiger was a notable Swiss mathematician known for his contributions to several areas of mathematics, particularly in the fields of topology, geometry, and graph theory. He is perhaps best known for Hadwiger's theorem and Hadwiger's conjecture, which relate to the properties of graph colorings and the connections between different types of geometric figures. His work has had a lasting impact on mathematical research and theory.
The Nikolai M. Knipovich Polar Research Institute of Marine Fisheries and Oceanography, commonly referred to as PINRO (its Russian acronym), is a prominent research institution located in Russia that specializes in marine and fisheries science. Established in 1930, the institute focuses on studying the Arctic and subarctic marine ecosystems, including fish populations, marine biodiversity, and oceanographic processes.
The Australasian Journal of Combinatorics is a peer-reviewed academic journal that focuses on research in combinatorics, which is a branch of mathematics dealing with the counting, arrangement, and combination of objects. Established in 1990, the journal publishes original research papers, survey articles, and other contributions related to various aspects of combinatorial theory and applications.
Pervez Hoodbhoy is a prominent Pakistani nuclear physicist, mathematician, and educator, known for his work in the field of physics as well as his advocacy for secularism, rationalism, and social justice.

In graph theory, an **independent set** (also known as a stable set) is a set of vertices in a graph, none of which are adjacent to each other. In other words, a set of vertices \( S \) is called an independent set if for every pair of vertices \( u \) and \( v \) in \( S \), there is no edge connecting \( u \) and \( v \) in the graph.
Henry Farquharson is not widely known in popular culture or history, so there might be limited information available about him. If you're referring to a specific individual, character, or concept, could you please provide more context or details?
In silico clinical trials refer to the use of computer simulations and computational models to conduct clinical trials, as opposed to traditional, in vivo (live organisms) trials or in vitro (test tube) studies. These digital simulations can replicate biological processes and predict the effects of medical interventions, therapies, or drugs within a virtual environment.
An Ocean General Circulation Model (OGCM) is a complex mathematical model used to simulate and understand the three-dimensional movement of ocean waters and their interactions with the atmosphere, land, and ice. These models are essential tools in oceanography and climatology as they help researchers predict ocean behavior, climate change effects, and global climate patterns.
Symbolic integration, also known as analytical integration, is a mathematical process used to find the integral of a function expressed in closed form, typically involving algebraic expressions, trigonometric functions, exponentials, and logarithms. Unlike numerical integration, which approximates the integral's value over a specific interval using numerical methods, symbolic integration provides an exact solution that is represented in a symbolic form.
The United Kingdom is home to several notable computer museums that celebrate the history and development of computing technology. Here are some prominent ones: 1. **The National Museum of Computing (TNMOC)** - Located at Bletchley Park, Buckinghamshire, this museum showcases the history of computing, focusing on the development of computers from the days of the Bletchley codebreakers during World War II to the present day.
"Elektronika" can refer to several different concepts, but it typically relates to electronics in various forms. Here are a few contexts in which the term may be used: 1. **Soviet Electronics Brand**: In the context of the former Soviet Union, "Elektronika" was a well-known brand that produced a wide range of electronic devices, including calculators, watches, and various consumer electronics.
GOST 10859 is a standard developed by the Russian Federal Agency for Technical Regulation and Metrology (Rosstandart). It pertains to the preservation and storage conditions of various types of food products. The GOST standards are part of a system established in the former Soviet Union to ensure quality and safety across a wide range of industries, including food production.
The risk premium is the return in excess of the risk-free rate of return that investors require to compensate them for the additional risk associated with a particular investment. It reflects the general principle that higher risk should be associated with the potential for higher returns. In finance, the concept is often applied in different contexts: 1. **Equity Risk Premium**: This is the additional return expected from investing in the stock market over a risk-free investment, such as government bonds.
Eva Andrei is a prominent physicist known for her research in condensed matter physics, particularly in the areas of magnetic materials, nanostructures, and spintronics. She has made significant contributions to understanding spin dynamics and magnetic phenomena at the nanoscale. In addition to her research, Andrei has been involved in academia, often serving as a professor and mentor to students in the field of physics.
Alan Tucker is a prominent figure in the field of operations research and mathematics, particularly known for his contributions to various areas such as optimization, decision analysis, and simulation. He has held positions at several academic institutions and has been involved in research and teaching. In particular, he is known for his work on decision-making under uncertainty and the development of simulation techniques.
Philip Kim could refer to various individuals, but without additional context, it's difficult to determine exactly who you're asking about. One prominent figure by that name is Philip Kim, a professor and researcher known for his work in physics and materials science, particularly in areas like graphene and two-dimensional materials.
K'nex Original Roller Coaster is a construction set that allows users to build their own roller coaster models using K'nex building pieces. These sets typically include a variety of rods, connectors, and sometimes other components like motors or track pieces, enabling users to create their own roller coaster designs that can incorporate loops, twists, and turns.
LEGO is a popular line of construction toys manufactured by the Danish company LEGO Group. The name "LEGO" is derived from the Danish words "leg godt," which mean "play well." The core product of LEGO consists of interlocking plastic bricks that can be assembled in countless ways to create structures, vehicles, and various designs.

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.
