This feature was initially developed by certain GPS and navigation system manufacturers to enhance the experience of capturing and sharing travel memories. Users can take a photo with a GPS-enabled camera or device, and the NavPix technology embeds the location information (like latitude and longitude) into the image file.
A needle roller bearing is a type of roller bearing that uses long, thin cylindrical rollers (needles) to provide support and reduce friction between moving parts. These bearings are designed for high load-bearing applications while maintaining a compact size. The rollers are typically much longer than their diameter, which allows for a greater surface area contact between the rollers and the bearing raceways.
Nekyia is a term that originates from ancient Greek literature, specifically referring to a type of narrative or theme involving a journey to the underworld or an exploration of death and the afterlife. It is notably featured in Homer's "Odyssey," where Odysseus performs a nekia, or necromantic ritual, to summon the spirits of the dead in order to gain wisdom and knowledge about his future.
Net force, often represented as \( F_{\text{net}} \), is the vector sum of all the individual forces acting on an object. It determines the object's acceleration according to Newton's second law of motion, which states that \( F = ma \), where: - \( F \) is the net force, - \( m \) is the mass of the object, - \( a \) is the acceleration of the object.
A network automaton is a mathematical model that extends the concept of cellular automata (CA) to a networked framework. In a cellular automaton, the system is typically defined on a grid where each cell can exist in one of a finite number of states and updates its state based on a set of rules defined by its neighbors. In the context of a network automaton, the structure is more complex as it involves nodes connected by edges, forming a graph or network.
Network medicine is an interdisciplinary field that applies the principles of network theory to the study and treatment of complex diseases. It views biological systems, particularly human health and disease, as networks of interacting components, such as genes, proteins, metabolites, and cellular pathways. This approach allows researchers and clinicians to better understand the intricate relationships and interactions within biological systems that contribute to health and disease states.
Raynor Johnson (1911-1994) was a prominent Australian physicist, best known for his work in astrophysics and as a pioneer in the field of science communication. He made significant contributions to the study of cosmic rays and the interactions of particles in space. Beyond his research, Johnson was recognized for his efforts to promote science education and public understanding of science, including his role in the Australian Academy of Science and various educational initiatives.
Neusis construction is a method used in classical geometry to create specific geometric figures and solve problems, particularly in the context of angle trisection and the construction of certain types of polygons. The term "neusis" comes from the Greek word for "to incline" or "to lean," as the construction involves using a marked straightedge (a ruler marked with specific lengths) to achieve the desired geometric outcome.
"New Bright" typically refers to New Bright Industries, a company known for producing a variety of remote-controlled vehicles, including cars, trucks, and other toys. Founded in 1955, the company has focused on creating innovative and entertaining products for children and hobbyists. They are recognized for their high-quality construction and engaging designs, offering both affordable and premium options within the toy vehicle market.
The Newfoundland Seamounts is a volcanic underwater mountain range located in the North Atlantic Ocean, specifically off the coast of Newfoundland, Canada. This seamount group is part of the larger Newfoundland Ridge and consists of several individual seamounts, which are underwater mountains formed by volcanic activity. The seamounts are of geological and ecological significance. They provide unique habitats for a variety of marine life, including fish, invertebrates, and other organisms.
Nikolaos Ch. Nikolaidis is a name that may refer to an individual in various fields such as academia, research, or industry, but without more specific context, it's difficult to provide detailed information. There could be notable individuals with this name, but more context on their contributions or area of expertise would help in identifying them accurately.
Nikola Tesla was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist known for his contributions to the development of alternating current (AC) electrical systems. Born on July 10, 1856, in Smiljan, Croatia (then part of the Austrian Empire), Tesla's work laid the groundwork for modern electrical power distribution.
The Paris Convention on Third Party Liability in the Field of Nuclear Energy, commonly known as the Paris Convention, is an international treaty established to create a framework for liability and compensation in the event of a nuclear accident. Adopted on July 29, 1960, in Paris, France, the convention aims to ensure that victims of nuclear incidents can receive appropriate compensation while also encouraging the development of nuclear power by establishing clear legal responsibilities for operators of nuclear installations.
Noble metals are a group of metals that exhibit remarkable resistance to corrosion and oxidation in moist air. They are typically characterized by their high value, ductility, and ability to conduct electricity. The primary noble metals include: 1. **Gold (Au)** - Known for its malleability, conductivity, and resistance to tarnish. 2. **Silver (Ag)** - Widely used in jewelry and electronics, though more prone to tarnishing than gold.
Noise calculation typically refers to the analysis or quantification of noise in various contexts, including environmental science, engineering, and data processing. The specifics can vary based on the application, but here are common areas where noise calculations are applied: 1. **Acoustic Noise**: In environmental studies or urban planning, noise calculations can determine the level of sound in decibels (dB) produced by traffic, construction, or industrial activities.
In mathematics, "nome" has a specific meaning related to elliptic functions. A nome is a complex variable often used in the context of elliptic integrals and functions. It is defined in relation to the elliptic modulus \( k \) (or the parameter \( m \), where \( m = k^2 \)).

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.
