Ternary fission is a nuclear reaction in which a heavy nucleus splits into three smaller nuclei, along with the release of energy and neutrons. This process is less common than the more widely known binary fission, where a nucleus splits into two smaller nuclei. In ternary fission, the original heavy nucleus—such as uranium-235 or plutonium-239—undergoes an instability that allows it to split into three fragments.
Miniature figures are small-scale representations of people, animals, or objects, typically used in hobbies such as tabletop gaming, modeling, and diorama building. These figures can range from a few millimeters to a few inches in height and are often made from materials like plastic, metal, or resin. In gaming contexts, miniature figures are commonly used in role-playing games (RPGs) like Dungeons & Dragons, board games, and wargaming.
Model boats are scaled-down replicas of real boats, ships, or vessels, created for various purposes, including sailing, display, or hobbyist enjoyment. They can range from simple toy versions to highly detailed and complex models that replicate the appearance and functionality of real boats. There are several categories and types of model boats, including: 1. **Static Models**: These models are not designed to move or be operated. They serve primarily as display pieces, often built to showcase craftsmanship or historical accuracy.
Model rocketry is a hobby and educational activity that involves the design, construction, and launch of small rockets, typically powered by solid rocket motors. These rockets are often made from lightweight materials such as cardboard, plastic, and balsa wood, and they can vary widely in size and complexity, from simple single-stage rockets to more advanced multi-stage designs. Key aspects of model rocketry include: 1. **Construction**: Model rocket enthusiasts build rockets from kits or from scratch.
Solar system models are representations that illustrate the structure and dynamics of our solar system, which includes the Sun, planets, moons, asteroids, comets, and other celestial bodies. These models can take various forms, including: 1. **Scale Models**: These are physical or digital representations that show the relative sizes and distances of solar system objects on a proportionate scale. They help visualize the vast distances between planets and their sizes compared to one another.
There are several replicas of the Statue of Liberty located around the world, each inspired by the original statue in New York Harbor. Here are some notable replicas: 1. **Las Vegas, Nevada, USA** - A famous replica stands outside the New York-New York Hotel and Casino, depicting a scaled-down version of the statue. 2. **Paris, France** - A replica of the Statue of Liberty is located on the Île aux Cygnes, a small island on the Seine River.
Ancient Greek atomist philosophers were thinkers in the 5th century BCE who proposed early theories about the nature of matter that laid the groundwork for later scientific concepts of the atom. The two most prominent figures in this school of thought were **Leucippus** and his student **Democritus**.
Ocellus lucanus, commonly known as the ocellate stag beetle, is a species within the family Lucanidae. Stag beetles are noted for the distinctive antler-like mandibles in males, which they utilize during mating displays and combat with other males. Ocellus lucanus is characterized by its glossy body and typically dark coloration. They can be found in various habitats, often in forested areas where they may feed on decaying wood or plant matter.
Prodicus is a figure from ancient Greek philosophy, known primarily as a Sophist. He lived around the 5th century BCE and was based in the city of Ceos (modern-day Kea). Prodicus is particularly recognized for his contributions to ethical philosophy and language, especially in the areas of semantics and the distinction between words and their meanings. One of Prodicus's most notable teachings is the idea that language is a tool for communication that can be manipulated to influence understanding and perception.
Algerian physicists are scientists from Algeria who specialize in the field of physics. They may work in various branches of physics, including theoretical physics, experimental physics, nuclear physics, condensed matter physics, astrophysics, and more. Some Algerian physicists are involved in academic research and teaching at universities, while others may work in industry, government research labs, or international organizations.
Mourad Dhina is known as a prominent figure in the field of Islamic finance and economics. He is recognized for his work in promoting the principles of Islamic finance and for his contributions to various financial institutions and organizations focused on ethical and Sharia-compliant financing practices. In addition to his work in finance, he has been involved in discussions around economic development, entrepreneurship, and the role of Islamic values in contemporary economics.
"Iraqi astronomers" could refer to several topics, including the history of astronomy in Iraq, notable astronomers from the region, or contemporary developments in astronomy within the country. 1. **Historical Context**: Ancient Mesopotamia, which largely corresponds to modern-day Iraq, is often regarded as the "cradle of civilization." This region was home to some of the earliest astronomers, who made significant contributions to the field.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
