The Numero sign, which looks like this: №, is a typographic symbol that denotes "number." It is commonly used to indicate ordinal numbers, typically preceding a numeral. For example, you might see "№ 5" to represent "number 5." The symbol is derived from the Latin word "numero," which means "by number." It is often used in contexts such as specifications, listings, and formal documents to identify items in a numbered sequence.
A numeronym is a type of abbreviation where a word or phrase is represented by its first letter, a number that represents the number of letters omitted, and its last letter. For example, the word "international" can be abbreviated as "i18n" (where "18" denotes the 18 letters between the first letter "i" and the last letter "n").
"Numbers" is an American television series that aired from 2005 to 2010. It was created by Nick Falco and is centered around an FBI agent, Don Eppes, who uses mathematical concepts and equations to help solve crimes, with the assistance of his brother, Charlie Eppes, a brilliant mathematician. The show features a combination of procedural crime-solving and the application of mathematics to real-world problems. Throughout its six seasons, "Numbers" aired a total of 118 episodes.
Nyaya is one of the six āstika (orthodox) schools of Hindu philosophy, which focuses on the study of logic and epistemology. Throughout its history, there has been a significant lineage of philosophers and teachers associated with the Nyaya school.
Oceanographic instrumentation refers to the various tools and devices used to study and monitor the physical, chemical, biological, and geological aspects of the ocean. This instrumentation plays a crucial role in oceanography, which is the scientific discipline that explores the ocean's properties, dynamics, ecosystems, and their interactions with the atmosphere and land.
Biological oceanography is a branch of oceanography that focuses on the study of marine organisms and their interactions with the ocean environment. It examines the biological aspects of the ocean, including the distribution, abundance, diversity, and behavior of marine life, as well as the ecological processes that govern these factors.
Classical elements refer to a set of fundamental substances that various ancient cultures believed to compose the physical universe and shape the qualities of matter. The concept of classical elements has appeared in various forms across different civilizations, but some of the most well-known are: 1. **Ancient Greece**: The Greek philosopher Empedocles proposed that four elements make up all matter: - **Earth**: Represents solidity and stability. - **Water**: Symbolizes fluidity and adaptability.
The Blackett effect refers to a phenomenon in astrophysics and planetary science where the angular momentum of a rotating body, such as a planet, is influenced by its magnetic field. Specifically, it suggests that the interaction between a planet's magnetic field and its rotation can lead to changes in the planet's rotation rate or angular momentum. This effect is often discussed in the context of Earth's rotation and its magnetic field, particularly regarding the potential impact on phenomena like plate tectonics or geodynamo processes.
The Albatross Expedition refers to a series of scientific research voyages conducted by the United States Fish Commission between 1882 and 1885. The expedition aimed to study the marine biology of the North Pacific Ocean, with a particular focus on fish populations and other marine life. One of the main objectives was to gather data on fish distribution, abundance, and the overall ecology of the ocean. The expedition was conducted aboard the U.S.
The hole argument is a philosophical and conceptual issue in the foundation of general relativity, primarily associated with the work of Albert Einstein and later discussions by philosophers and physicists. It arises in the context of the interpretation of spacetime and the nature of physical objects within it. ### What is the Hole Argument? 1. **Concept of the Hole**: Imagine a region of spacetime where the gravitational field is described by a specific metric (the mathematical representation of spacetime geometry).
As of my last knowledge update in October 2023, there is no widely recognized or established theory of gravitation known specifically as "Nordström's theory.
The term "sublunary sphere" originates from ancient and medieval cosmology, particularly in the context of Aristotelian philosophy. In this framework, the universe was typically divided into two main realms: the supralunary (above the moon) and the sublunary (below the moon). 1. **Sublunary Sphere**: This realm is considered to encompass everything on Earth and the atmosphere surrounding it, including all terrestrial phenomena.
Vector Meson Dominance (VMD) is a theoretical concept in quantum field theory and particle physics that describes how certain processes involving photons can be effectively treated in terms of the exchange of vector mesons. The basic idea is that, under certain conditions, the interaction of photons with hadronic matter can be modeled as being mediated by vector mesons, such as the ρ (rho), ω (omega), and φ (phi) mesons.
A fixed-point ocean observatory is a type of research facility or system that is deployed in marine environments to monitor and collect continuous data on various oceanographic parameters. These observatories are typically anchored at specific locations in the ocean and can provide long-term observations that are crucial for understanding ocean processes, climate change, marine ecosystems, and other important scientific questions.
Flow tracer is a term that can refer to different things depending on the context. Here are a couple of possible interpretations: 1. **Computer Graphics and Visualization**: In visual computing, a flow tracer can refer to an algorithm or tool used to visualize fluid flow or motion in a medium. It often involves tracing the paths (or "lines") that particles would follow in a flow field, allowing for the visualization of complex fluid dynamics. This can be used in simulations, animations, or scientific visualization.
Fracture zones are significant geological features found on the ocean floor, particularly in the context of plate tectonics. They are characterized by long, narrow regions where the oceanic crust has been broken and displaced due to tectonic activity. These zones are the result of complex interactions between tectonic plates. Key characteristics of fracture zones include: 1. **Orientation**: Fracture zones typically run perpendicular to mid-ocean ridges, which are underwater mountain ranges formed by tectonic plates moving apart.
The Carbonate Compensation Depth (CCD) is the ocean depth at which the rate of carbonate accumulation equals the rate of carbonate dissolution. Below this depth, the conditions in the ocean become more acidic due to an increase in the partial pressure of carbon dioxide (pCO2), which leads to the dissolution of calcium carbonate (CaCO3) materials such as shells and sediments.

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.
