Justus von Liebig (1803–1873) was a German chemist who is often referred to as one of the founding figures of organic chemistry. He made significant contributions to the fields of agricultural chemistry, biochemistry, and the study of the chemistry of living organisms. Liebig is best known for developing the concept of the synthesis of organic compounds and for his work on the importance of nitrogen in plant nutrition, which laid the groundwork for modern agricultural practices and fertilizer production.
Karl Gegenbaur (1826–1903) was a prominent German zoologist and paleontologist known for his work in evolutionary biology and comparative anatomy. He is often regarded as a founding figure in the field of evolutionary morphology, which studies the relationship between the structure of organisms and their evolutionary history. Gegenbaur made significant contributions to the understanding of the vertebrate skeleton and the classification of various animal groups.
Norman Pirie (1913-1997) was a notable British biochemist and virologist, best known for his pioneering research in the fields of plant viruses and molecular biology. He made significant contributions to the understanding of viral structures and the nature of genetic material. Pirie’s work helped to clarify the role of nucleic acids in the replication of viruses and advanced the study of virology, particularly in relation to plant pathogens.
Roderick Murchison (1792–1871) was a prominent Scottish geologist and one of the key figures in the early development of geological science in the 19th century. He is best known for his work on the geology of Europe, particularly for his studies of the geology of Scotland and his identification of the Silurian system of rocks, which he named after the Silures, an ancient Celtic tribe in what is now Wales.
Simon Newcomb (1835–1909) was a prominent American mathematician, astronomer, and professor, known for his significant contributions to the fields of astronomy, mathematics, and statistical analysis. He played a key role in the development of astronomical tables and various methods of astronomical calculations. Newcomb is best known for his work on celestial mechanics and his formulation of the Newcomb's formula for determining the positions of celestial bodies.
Thomas Hunt Morgan (1866–1945) was an American evolutionary biologist and geneticist who made significant contributions to the field of genetics. He is best known for his work on the fruit fly Drosophila melanogaster, which he used as a model organism to study inheritance and gene mapping. Morgan and his colleagues, including his students who became known as the "Morgan group," discovered the chromosomal basis of heredity, demonstrating that genes are located on chromosomes.
The folded cube graph is a type of mathematical graph that can be derived from the hypercube graph, particularly useful in the field of combinatorial design and graph theory. The concept is particularly involved in the analysis of topology, network design, and parallel processing. ### Definition: The \(n\)-dimensional folded cube graph, denoted \(FQ_n\), is constructed from the \(n\)-dimensional hypercube \(Q_n\).
Deming regression, also known as Deming regression analysis or errors-in-variables regression, is a statistical method used to estimate the relationships between two variables when there is measurement error in both dependent and independent variables. Unlike ordinary least squares (OLS) regression, which assumes that there is no error in the independent variable, Deming regression accounts for errors in both variables. The method was developed by W.
Blanuša snarks are a specific type of snark, which is a type of non-trivial, 3-regular (each vertex has degree 3), edge-colored graph that lacks any homomorphic mapping to a 3-colorable graph, thus making it non-colorable with three colors. These graphs are named after the Croatian mathematician Josip Blanuša, who discovered them.
The Dürer graph is a specific type of graph in the field of graph theory, named after the German painter and printmaker Albrecht Dürer. It is a highly symmetrical graph that has 12 vertices and 24 edges. The graph can be represented as a 3-dimensional object, which resembles a cube, and it is known for its interesting geometric properties.
The Generalized Petersen graph is a family of graphs that generalize the structure of the well-known Petersen graph. These graphs are denoted as \( GP(n, k) \), where \( n \) and \( k \) are positive integers. The Generalized Petersen graph is defined using two parameters: - \( n \): the number of vertices in the outer cycle (which is a simple cycle graph with \( n \) vertices).
In graph theory, a **snark** is a specific type of graph that has some interesting properties. Snarks are defined as: 1. **Cubic Graphs**: Snarks are always cubic, meaning every vertex in the graph has a degree of 3. 2. **Not 3-Colorable**: A characteristic feature of snarks is that they cannot be colored with 3 colors without having two adjacent vertices sharing the same color.
Dual trigger insurance is a specialized form of insurance designed to provide coverage in situations where two specific conditions, or "triggers," must be met for the insurance payout to be activated. This type of insurance is often used in contexts where a single event may not be sufficient to warrant a claim, or when the insured wants to ensure comprehensive coverage under more restrictive circumstances.
The Capirola Lutebook is a significant music manuscript compiled in the 16th century, attributed to the Venetian musician and composer Silvestro Ganassi. It is named after the lute player and composer Giovanni Capirola, who is often associated with the collection. The manuscript is a key source for lute music, containing a variety of pieces for lute, including solo compositions and arrangements.
A Generalized Verma module is a concept from the representation theory of Lie algebras, particularly in the context of infinite-dimensional representations and the study of parabolic subalgebras.
KRI Rigel (933) is a vessel of the Indonesian Navy, specifically classified as a fast attack craft. It is part of the KCR-40 class, which encompasses a series of vessels designed primarily for patrol and surveillance duties. KRI Rigel is notable for its modern design and capabilities, which include engaging in anti-surface and anti-air operations. The ship is equipped with various weapons systems and advanced technology to fulfill its role in national defense and maritime security.
The Institut d'Astrophysique de Paris (IAP) is a research institute located in Paris, France, dedicated to the study of astrophysics and related fields. It is part of the French National Center for Scientific Research (CNRS) and focuses on various areas of astrophysics, including cosmology, stellar physics, galactic dynamics, and the study of the universe's structure and evolution.
The Dvoretzky–Kiefer–Wolfowitz (DKW) inequality is a result in probability theory concerning the convergence of the empirical distribution function to the true cumulative distribution function. Specifically, it provides a bound on the probability that the empirical distribution function deviates from the true distribution function by more than a certain amount.
"Balanced flow" can refer to different concepts depending on the context in which it's used. Here are a few interpretations across various fields: 1. **Fluid Dynamics**: In fluid mechanics, balanced flow might refer to a scenario where the forces acting on a fluid moving through a channel or pipe are in equilibrium. This means that the driving forces (like pressure, gravity, etc.) are equal to the opposing forces (like friction and resistance), resulting in steady, uniform flow.
Zonal wavenumber is a term used in atmospheric science and oceanography to describe the spatial frequency of wave patterns in a zonal (east-west) direction in a periodic system, like the Earth's atmosphere or ocean. It quantifies how many wavelengths fit into a given distance in the zonal direction.

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.
