"Perpetuant" is not a standard term widely recognized in English. It appears to be either a misspelling or a misinterpretation of a different word. If you meant "perpetual," it refers to something that lasts indefinitely or is continuous without interruption. This term is often used in contexts such as perpetual motion, perpetual calendars, or in legal contexts like perpetual trusts.
Mathematical artists are individuals who combine mathematics and art to create visual representations that explore mathematical concepts or use mathematical techniques. This blend can take various forms, including: 1. **Geometric Art**: Utilizing shapes, patterns, and spatial arrangements derived from geometric principles to create visually engaging pieces. 2. **Fractals**: Artists may use fractal mathematics to generate intricate designs that display self-similar patterns at different scales, often creating mesmerizing visual results.
In physics, "concepts" refer to fundamental ideas or principles that help explain the behavior of the physical universe. These concepts serve as the building blocks for understanding more complex phenomena and are essential for developing theories, conducting experiments, and solving problems. Here are some key concepts in various branches of physics: 1. **Mechanics**: - **Force**: An interaction that causes an object to change its velocity (accelerate).
Condensed matter physics is a branch of physics that deals with the physical properties of condensed phases of matter, particularly solids and liquids. It focuses on understanding how the collective behavior of large numbers of atoms or molecules gives rise to various physical phenomena. Key areas of research in condensed matter physics include: 1. **Crystallography and Solid State Physics**: Study of the arrangement of atoms in solids and the resulting properties, such as electrical conductivity, magnetism, and optical behaviors.
In propositional logic, a theorem is a statement that has been proven to be true based on a set of axioms and inference rules within a formal system. More specifically, a theorem is a propositional formula that can be derived from axioms using logical deductions. Here are some key points regarding theorems in propositional logic: 1. **Propositions**: In propositional logic, statements are represented as propositions, which are either true or false.
"Electricity stubs" typically refers to short segments of electrical wiring or connectors that are used in various applications. In a broader context, the term can also apply to temporary connections or short spans of electrical circuits. Here are a few relevant contexts: 1. **Electrical Wiring**: In construction or renovation projects, electricity stubs might refer to short pieces of wire left exposed after the installation of outlets or fixtures. These stubs can be used for future connections.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
