Pentation is a mathematical operation that is part of the family of hyperoperations, which extend beyond exponentiation. Hyperoperations are defined in a sequence where each operation is one rank higher than the previous one, starting from addition, multiplication, exponentiation, and moving on to tetration and beyond. The sequence is as follows: 1. Addition (a + b) 2. Multiplication (a × b) 3. Exponentiation (a^b) 4.

A list of retired numbers typically refers to the jersey numbers that have been taken out of circulation by a sports team or organization to honor a player, coach, or significant figure associated with that team. When a number is retired, no other player on the team can wear that number in the future. Retired numbers are a common tradition in many sports leagues, including the NFL, NBA, MLB, NHL, and college sports.
A positional numeral system is a method of representing numbers in which the value of a digit depends on its position within a number. In such systems, each position corresponds to a power of a base, and the digits in the number are multiplied by these powers to determine the overall value. ### Key Features of Positional Numeral Systems: 1. **Base**: The base (or radix) of a positional system indicates how many distinct digits (including zero) are available.
2013 FS28 is a near-Earth object (NEO) categorized as an asteroid. It was discovered on March 30, 2013, and belongs to the Apollo group of asteroids, which are characterized by their orbits that cross that of Earth's. It has gained attention due to its close approaches to Earth. Asteroids like 2013 FS28 are monitored closely by astronomers to assess any potential impacts with Earth in the future.
ENGIN-X is a unique neutron scattering research facility located at the UK's ISIS Neutron and Muon Source, which is part of the Rutherford Appleton Laboratory in Oxfordshire. ENGIN-X is specifically designed for engineering and structural materials studies, providing advanced neutron diffraction capabilities to investigate the microstructure and phase distribution of materials.
Offensive programming is a term that is not commonly used or standardized in the field of software development, and it may refer to a few different concepts depending on the context. Here are a couple of interpretations: 1. **Security-Driven Development**: In some contexts, "offensive programming" might refer to a security-focused approach to software development, analogous to "offensive security" in cybersecurity.

(144897) 2004 UX10 is a near-Earth object (NEO) classified as an asteroid. Specifically, it is part of the Apollo group of asteroids, which are characterized by their orbits that cross Earth's orbit. Discovered in 2004, it is an example of a potentially hazardous asteroid due to its size and proximity to Earth's orbit.
(84522) 2002 TC302 is a near-Earth asteroid discovered on October 1, 2002. It is classified as an Apollo-type asteroid, which means it has an orbit that crosses Earth's orbit. These types of asteroids can come quite close to Earth but are not necessarily on a collision course with our planet.
Integral energy typically refers to the total energy associated with a system or process, taking into account all forms of energy present and the various ways that energy can be stored and transferred. Though the term "integral energy" isn't widely used in scientific literature like other specific types of energy (such as kinetic, potential, thermal, etc.), it may appear in certain contexts, often emphasizing a holistic approach to energy analysis.
A tensiometer is an instrument used in soil science to measure the tension or moisture potential of water in soil. It provides valuable information about soil water content and helps in understanding the water availability for plants. **How a Tensiometer Works:** 1. **Components**: A typical tensiometer consists of a sealed, water-filled tube with a porous ceramic or plastic tip at the bottom, connected to a manometer or pressure gauge.
Atmospheric lidar (Light Detection and Ranging) is a remote sensing technology that uses laser light to measure various atmospheric properties. It operates by sending out a pulse of laser light into the atmosphere and measuring the time it takes for the light to be scattered back to the sensor. By analyzing the returned signal, atmospheric lidar can provide valuable information about the atmosphere's composition, structure, and dynamics.
Transcranial magnetic stimulation (TMS) is a non-invasive neurological procedure that uses magnetic fields to stimulate nerve cells in the brain. It is primarily used for therapeutic and diagnostic purposes, particularly in the treatment of various mental health conditions, such as depression, anxiety, and OCD, as well as neurological disorders like Parkinson's disease and stroke rehabilitation. The procedure involves placing a magnetic coil near the scalp, which generates short pulses of magnetic energy.

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.
