The list of cancelled LEGO media includes various projects that were planned but ultimately not produced or released. This can encompass a variety of formats, including movies, television shows, video games, and other media related to the LEGO brand. Some notable examples may include: 1. **LEGO Movies and Specials**: Occasionally, planned LEGO films or animated specials may be announced but later shelved due to various reasons, including creative differences or changes in corporate direction.
Cyprus is divided into several districts, each containing various cities, towns, and villages.
Group-1 ISBN publisher codes refer to the ISBN prefixes assigned to publishers in specific countries or territories. The ISBN (International Standard Book Number) system uses a series of prefixes to identify publishers and their books uniquely worldwide. The ISBN is typically structured as a 13-digit number, divided into five parts: 1. **Prefix Element**: This is usually either 978 or 979. 2. **Registration Group Element**: This identifies the country, geographical region, or language area.
The Jupiter trojans are a subset of asteroids that share Jupiter's orbit around the Sun, specifically positioned at stable Lagrange points, L4 and L5. The Greek camp refers to the L4 group, which is associated with characters from the Trojan War. The complete list of Jupiter trojans in the Greek camp (from 1 to 100,000) is extensive.
The Jupiter trojans are a group of asteroids that share an orbit with Jupiter, located at stable Lagrange points (L4 and L5) ahead of and behind the planet in its orbit around the Sun. The Greek camp refers to one of the two main groups of Jupiter trojans, named after figures from Greek mythology associated with the Trojan War.

The list of minor planets numbered from 106001 to 107000 includes a range of asteroids that are part of the larger classification of minor planets in our solar system. These minor planets are typically small rocky bodies that orbit the Sun, primarily in the asteroid belt located between Mars and Jupiter.
The list of minor planets numbered from 12001 to 13000 includes various small solar system bodies, primarily asteroids, that have been discovered and cataloged by astronomers. Each minor planet is given a unique identification number upon discovery, and many also have designated names.
The list of minor planets numbered from 146001 to 147000 includes a range of asteroids that have been assigned specific numbers by the Minor Planet Center. These minor planets vary in size, location, and orbital characteristics, and they are not typically well-known names like the major planets in our solar system.
The list of minor planets numbered 150001 to 151000 includes various small celestial bodies that orbit the Sun. These minor planets, often referred to as asteroids, have been cataloged by the Minor Planet Center and are officially designated with their designated numbers.
The list of minor planets numbered from 186001 to 187000 includes various small celestial bodies in our solar system, also known as asteroids. Each of these minor planets has been assigned a unique number and often has a name associated with it, reflecting a variety of themes including mythology, literature, historical figures, and more.
The list of minor planets numbered 207001 to 208000 includes various small celestial bodies (typically asteroids) found in the solar system. These objects are cataloged by the Minor Planet Center and are designated with unique numerical identifiers.
The List of minor planets 211001–212000 refers to a sequence of numbered minor planets (also known as asteroids) that have been cataloged by the Minor Planet Center. Minor planets are small celestial bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter, but they can also be located throughout the solar system.
The List of minor planets from 216001 to 217000 consists of identified asteroids within that numerical range. Each minor planet has its own unique identification number, name, and often additional information such as discovery date and orbital characteristics. This list typically includes a mixture of numbered asteroids which have been discovered and cataloged by astronomers.
The list of minor planets from 226001 to 227000 includes a range of numbered asteroids that have been identified and cataloged by the Minor Planet Center. These asteroids typically vary in size, shape, and orbital characteristics. Specific details about each minor planet, including their names, discovery dates, physical properties, and orbits, can be found in databases and catalogs maintained by organizations such as the International Astronomical Union (IAU) or the Minor Planet Center.
The list of minor planets from 230001 to 231000 includes a range of asteroids and other small celestial objects that have been designated with numbers in that range. This list is part of the broader catalog of minor planets maintained by astronomers and institutions like the International Astronomical Union (IAU). Each minor planet has a unique number, and many may also have provisional designations or names.
Lac, also known as lac resin, is a natural resin secreted by certain species of lac insects, primarily from the family Kerridae. The primary species involved in lac production are the female insects of the Laccifer lacca species, which primarily inhabit trees in tropical and subtropical regions, particularly in India, Thailand, and Myanmar.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
