"Personalities" by Ral Partha was a series of miniature figures designed primarily for tabletop gaming. Ral Partha was known for producing high-quality miniatures that could be used in role-playing games, wargames, and other types of gameplay. The "Personalities" line included a variety of character figures that represented different archetypes and classes common in fantasy settings, such as knights, wizards, rogues, and monsters.
As of my last knowledge update in October 2021, there isn't widely recognized information regarding an individual named Michael Stillman that stands out in popular culture, history, or current events. It's possible that he could be a private individual, a professional in a specific field, or perhaps has gained prominence after my last update.
Michael Strickland is a physicist known for his work in the field of high-energy nuclear physics, particularly in relation to the study of heavy-ion collisions and the properties of quark-gluon plasma. He has contributed to theoretical developments and has been involved in research at major facilities like the Large Hadron Collider (LHC) and the Relativistic Heavy Ion Collider (RHIC).
Muhammad Baqir Yazdi, also referred to as Muhammad Baqir al-Majlisi, was a prominent Shia Islamic scholar, theologian, and jurist who lived in the 17th century (1627-1699). He was a significant figure in the development of Shia theology and the compilation of hadith (sayings and actions of the Prophet Muhammad and the Imams in Shia Islam).
Murray R. Spiegel is an author and educator known primarily for his contributions to mathematics, particularly in the field of applied mathematics and statistics. He is most notable for his books that are widely used in academic settings, especially "Schaum's Outline of Advanced Mathematics for Engineers and Scientists" and other titles in the Schaum's Outline series. These books are popular for their clear explanations, practical examples, and problem-solving approaches, making complex topics more accessible to students and working professionals.
Pareto efficiency, also known as Pareto optimality, is an economic concept that describes a situation in which resources are allocated in a way that no reallocation can make one individual better off without making at least one other individual worse off. In simpler terms, an allocation is Pareto efficient if there are no possible changes that could improve someone's situation without harming someone else's situation.
The Ocean Tracking Network (OTN) is a global initiative focused on studying and monitoring the movement and behavior of marine animals in the ocean. Established to enhance our understanding of marine ecosystems and the implications of human activities on these habitats, OTN employs a network of acoustic receivers and satellite tracking technologies to gather data on various marine species, including fish, sharks, and marine mammals.

Can be seen as a cheap form of DNA sequencing that only test for a few hits. Some major applications:
A Higgs bundle is a mathematical structure that arises in the study of geometry and mathematical physics, particularly in the context of gauge theory and string theory. It consists of a vector bundle equipped with a differential form, called a Higgs field, that satisfies certain conditions. More specifically, a Higgs bundle can be described as follows: 1. **Vector Bundle**: You start with a vector bundle \( E \) over a complex algebraic or differentiable manifold \( X \).
"Crusader 101" could refer to a variety of topics depending on the context, including historical studies, educational programs, gaming, or specific organizations. One possible interpretation is that it relates to a beginner's course or introduction to the historical Crusades, which were a series of religious wars during the medieval period, particularly focused on the Holy Land.
In computing, particularly in the context of peer-to-peer (P2P) file sharing networks and torrenting, a "leecher" refers to a user who downloads files from other users but does not share or upload those files back to the network. This term is often used to describe individuals who take advantage of the resources made available by "seeders," who are users that upload and share files.
The Gummel-Poon model is a semiconductor device modeling framework, primarily used for the simulation of bipolar junction transistors (BJTs) and some MOSFET characteristics. It was developed by the physicists Gummel and Poon in the 1970s and has become a foundational element in circuit simulation tools.
Lemoine's problem, named after the French mathematician Georges Lemoine, is a conjecture in number theory concerning the representation of odd integers as sums of prime numbers. Specifically, the conjecture posits that every odd integer greater than 5 can be expressed as the sum of an odd prime and an even semiprime (a product of two primes, where at least one of the primes is 2).
Transport in culture refers to the ways in which transportation systems, technologies, and practices influence and shape cultural dynamics within societies. It encompasses various dimensions, including: 1. **Cultural Exchange**: Transport facilitates the movement of people and goods, enabling the exchange of ideas, traditions, and customs among different cultures. This can lead to cultural blending and the emergence of new social practices. 2. **Regional Identity**: Different modes of transport can contribute to regional identities.
Transport safety refers to the measures, practices, regulations, and technologies designed to ensure the safe movement of people and goods across various modes of transportation, including road, rail, air, and maritime. The objective of transport safety is to minimize the risk of accidents, injuries, and fatalities while promoting an efficient and reliable transportation system. Key components of transport safety include: 1. **Regulations and Standards**: Governments and international organizations establish laws, regulations, and standards to ensure safety in transportation.
The Galerie des Carrosses, also known as the Gallery of Coaches, is a notable exhibition space located in the Palace of Versailles, France. It houses a collection of historic carriages that were used by French royalty, particularly during the reign of Louis XIV and his successors. The gallery showcases various types of coaches, including state coaches, ceremonial vehicles, and everyday carriages that reflect the opulence and craftsmanship of the era.
Surfactant, short for surface-active agent, is a substance that reduces surface tension in liquids. Surfactants are typically amphiphilic molecules, meaning they have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts. This unique structure allows them to accumulate at interfaces, such as between air and water or oil and water, altering the properties of the surface.

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
