N-body units refer to a system of natural units used in astrophysics and computational astrophysics, specifically in simulations of gravitational systems involving multiple bodies, or N bodies. In these simulations, it is often useful to express quantities in a way that simplifies calculations and highlights essential physical relationships. The N-body units are typically derived from choosing characteristic scales for length, mass, and time based on the system being studied.
1999 Software is known for creating multiplayer online games, particularly unique experiences that include real-time interactions and engaging environments. One of its notable projects is the game **"A Tale in the Desert,"** which is a social and economic simulation MMO set in ancient Egypt. This game focuses heavily on crafting, community, and cooperation among players rather than combat, distinguishing it from many other MMOs in the market.
A lane meter is a unit of measurement used primarily in the context of transportation and road traffic analysis. It represents the length of a roadway lane and is often used to measure facilities such as highways, streets, and other road infrastructure. Specifically, a lane meter quantifies the linear extent of a single lane of traffic.

The abcoulomb (abC) is a unit of electric charge in the centimeter-gram-second (CGS) system of units, specifically in the electromagnetic (emu) system. It is defined as the amount of charge that, when placed in a vacuum, will produce a force of one dyne on an equal charge placed one centimeter away.
The term "fall" can refer to different units of measurement or concepts depending on the context, but in the context of physics and engineering, it is not a standard unit of measurement like meters or seconds. Instead, the term "fall" is often associated with gravitational potential energy or the motion of an object when it descends under the influence of gravity.
As of my last knowledge update in October 2021, there isn't a widely recognized term or concept known as "Fistmele." It could possibly be a typo, a specific name, a term from a niche community, or something that has emerged more recently.
The hasta is an ancient unit of measurement that originated in India and was historically used to measure length. It is traditionally defined as the distance from the tip of the thumb to the tip of the little finger when the fingers are fully extended. This unit is not standardized and can vary slightly depending on the individual, but it is generally considered to be about 18 to 24 inches (approximately 45 to 60 centimeters).
"2003 software" usually refers to software that was released in or around the year 2003. One of the most notable examples is Microsoft Office 2003, which included applications such as Word, Excel, PowerPoint, Outlook, and Access. Released as part of the Microsoft Office suite, it introduced various improvements and new features over its predecessor, Office XP, including better collaboration tools, enhanced formatting options, and improved support for XML.
The Paris inch, also known as the "French inch" or "Parisian inch," is a unit of measurement used in France and some other countries prior to the adoption of the metric system. It is equivalent to approximately 2.707 centimeters. The Paris inch was part of a system of measures that included other units like the Paris foot and the Paris yard. In general usage, however, the standard inch (which is defined as exactly 2.
Parsec can refer to a couple of different concepts depending on the context: 1. **Astronomy**: In astronomy, a parsec (pc) is a unit of distance used to measure astronomical distances. It is defined as the distance at which one astronomical unit (the average distance from the Earth to the Sun) subtends an angle of one arcsecond. One parsec is equivalent to approximately 3.26 light-years, or about 30.9 trillion kilometers (19.
"2007 software" usually refers to a suite of applications released by Microsoft as part of Microsoft Office 2007. This suite includes popular programs such as: 1. **Microsoft Word 2007** - A word processing application. 2. **Microsoft Excel 2007** - A spreadsheet application. 3. **Microsoft PowerPoint 2007** - A presentation graphics program. 4. **Microsoft Access 2007** - A database management system.
A microgram is a unit of mass in the metric system, symbolized as "µg." It is equal to one millionth of a gram (1 µg = 0.000001 grams) or one billionth of a kilogram (1 µg = 0.000000001 kg). Micrograms are commonly used in fields such as medicine, biology, and chemistry to measure very small quantities of substances, such as vitamins, drugs, or pollutants.
Micropound, often referred to in the context of currency or financial systems, is not widely recognized as a formal currency or financial unit like the pound sterling or the US dollar. However, the term might be used in niche contexts or specific projects, such as in discussions about micropayments or digital currencies.
"Ratti" can refer to different things depending on the context: 1. **Weight Measurement**: In some cultures, particularly in India, "Ratti" is a traditional unit of weight used primarily for gemstones and pearls. One Ratti is approximately equal to 0.91 grams. It is often used in jewelry and for the sale of precious stones.
Atom (time) refers to a timekeeping system that is based on the vibrations of atoms, specifically using atomic clocks. Atomic clocks are extremely precise timekeeping devices that measure time based on the oscillations of atoms, typically cesium or rubidium. The most commonly known standard for atomic time is based on the vibrations of cesium atoms.
Discrete-time proportional hazards is a statistical modeling approach used in survival analysis, which deals with time-to-event data. This approach is particularly useful when the time until an event occurs (like failure, death, or another outcome) is recorded at discrete time intervals rather than continuously. ### Key Features: 1. **Discrete Time**: In this model, time is divided into discrete intervals (e.g.
A calendar year is a period of one year that is based on the Gregorian calendar, which is the most widely used civil calendar today. It consists of 12 months, totaling 365 days in a standard year and 366 days in a leap year. The calendar year starts on January 1 and ends on December 31. In different contexts, the term "calendar year" can have specific implications: 1. **Fiscal Year vs.

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.
