Ruwen Ogien was a French philosopher known for his work in ethics, moral philosophy, and social theory. He was particularly interested in issues related to moral relativism, the nature of human happiness, and the ethics of everyday life. Ogien contributed to various areas of philosophical thought, often exploring contemporary moral dilemmas and the implications of ethical theories in practical situations. His engaging style made his ideas accessible to a broader audience, and he was actively involved in philosophical discussions beyond academic circles.
A "tracking ship" typically refers to a vessel equipped with technology and systems that allow it to monitor, locate, or follow other vessels, objects, or even events in real-time. The term can be applied in various contexts: 1. **Maritime Navigation**: Tracking ships may refer to commercial shipping vessels that use GPS and other navigation technology to track their own movements or the positions of other ships, ensuring safe navigation and avoiding collisions.
Cavalieri's quadrature formula, named after the Italian mathematician Bonaventura Cavalieri, is a mathematical principle used to compute the area under a curve. The formula is particularly useful in the context of integral calculus and can be seen as a way to approximate the area under a function.
Physical Security Information Management (PSIM) refers to a comprehensive approach to managing security data and systems for the physical protection of people, property, and assets. It integrates various security technologies and systems, such as surveillance cameras, access control systems, alarm systems, and sensors, into a centralized platform. The goal of PSIM is to enhance situational awareness, streamline security operations, and improve response times to incidents.
A wildfire, also known as a bushfire, forest fire, or grassfire, is an uncontrolled fire that burns in wildland areas, including forests, grasslands, and other ecosystems. Wildfires can occur naturally due to events such as lightning strikes, but they are often exacerbated or ignited by human activities, such as campfires, discarded cigarettes, or arson.
A salt bridge refers to a non-covalent interaction that occurs between oppositely charged ionizable groups, typically amino acid side chains, in a protein or in supramolecular assemblies. Here’s a breakdown of salt bridges in both contexts: ### In Proteins: 1. **Definition**: A salt bridge in proteins usually involves the electrostatic attraction between the carboxylate group (e.g., from aspartate or glutamate) and an ammonium group (e.g.
The Transfer-Matrix Method (TMM) is a mathematical technique used primarily in statistical physics, condensed matter physics, and engineering to analyze the properties of one-dimensional systems such as spin chains, quantum systems, and wave propagation in stratified media. The method is particularly useful for studying systems that can be described in terms of discrete degrees of freedom arranged in a lattice.
As of my last knowledge update in October 2023, "Fragplan" does not appear to refer to a widely recognized term, concept, or entity in publicly available literature or common usage. It may be a proprietary term, a name of a specific product, or a concept that emerged after my last update.
Sara Billey is a mathematician known for her work in topology, particularly in the area of geometric group theory and low-dimensional topology. She has contributed to various research topics, including the study of mapping class groups and the interaction between algebraic structures and topological spaces. Billey is also recognized for her role in mathematics education and outreach, actively engaging in efforts to promote diversity and inclusion within the mathematical community.
Francesco Bonatelli could refer to a specific individual, but as of my last update in October 2023, there isn't any widely recognized or prominent figure by that name in public domains such as politics, arts, science, or other notable fields. It’s possible that he may be a private individual or a lesser-known figure, so additional context would be necessary for a more precise identification.
A "transit desert" is a term used to describe areas where public transit services are sparse or non-existent, making it difficult for residents to access public transportation options. This can occur in regions with low population density, inadequate transit infrastructure, or limited service hours. In transit deserts, people often have to rely on personal vehicles, which can pose challenges for those who do not own a car, including low-income individuals, the elderly, and people with disabilities.
In group theory, a subgroup \( H \) of a group \( G \) is said to be **transitively normal** in \( G \) if it is normal in every subgroup of \( G \) that contains \( H \).
Franci Demšar is a Slovenian politician and member of the political party United Left (Zeleno Levo). He has served in various capacities within the Slovenian government and is known for his work in social issues and his advocacy for progressive policies.
A semiautomaton is a concept used primarily in theoretical computer science and automata theory. It refers to a computational model that operates under rules that are less restrictive than those of a full automaton. While traditional automata, such as finite automata, have a complete set of states and transitions, a semiautomaton may not have all transitions defined for each state or may have an incomplete structure.
"Physics of the Future" is a book written by physicist Michio Kaku, published in 2011. In this work, Kaku explores the potential advancements and innovations that may transform our world over the next several decades, based on current scientific trends and theoretical ideas. The book is divided into chapters that focus on various fields, including: 1. **Computing** - Insights on quantum computing and how it could revolutionize information processing.
Francis Kiernan could refer to various individuals, but without specific context, it's unclear who you mean.
"Transport by decade" typically refers to the evolution of transportation methods, infrastructure, technology, and industry trends over specific ten-year periods. This concept allows us to examine how transport systems have developed, adapted, and changed in response to societal needs, technological advancements, and economic factors over time.
A tropical year, also known as a solar year, is the time it takes for the Earth to complete one full orbit around the Sun, measured from one vernal equinox to the next. This duration is approximately 365.242190 days, which is why our calendar year is typically 365 days, with a leap year occurring every four years to accommodate for the extra approximately 0.242190 days. The tropical year is significant because it aligns the calendar year with the seasons.

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.
