In ballistics, "elevation" refers to the vertical angle at which a projectile needs to be aimed to strike a target at a certain distance. It is usually expressed in degrees and pertains to the upward or downward adjustment of the firearm's sights relative to a horizontal line.
Euler angles are a set of three parameters used to describe the orientation of a rigid body in three-dimensional space. They are named after the Swiss mathematician Leonhard Euler. Euler angles are commonly used in fields like robotics, aerospace, and computer graphics to represent the rotational position of objects. The three angles typically used to represent rotation are often denoted as: 1. **Yaw (ψ)** - This angle represents the rotation around the vertical axis (z-axis).
TriX (Turtle RDF/XML) is a serialization format used to encode RDF (Resource Description Framework) data. It is an XML-based format that provides a way to represent RDF graphs in a way that is both human-readable and machine-readable. TriX is designed to facilitate the storage and exchange of RDF data, offering a way to serialize the triples that form RDF statements (subject, predicate, object).
Term-rewriting programming languages (TRPLs) are programming languages that are based on the principles of term rewriting, a formal system used primarily in the fields of computer science and logic. Term rewriting involves manipulating symbolic expressions (terms) according to a set of defined rules, allowing for computation and the transformation of these terms. ### Key Concepts 1. **Terms**: In term rewriting, a term can be a variable, a constant, or a function applied to arguments.
Explicit substitution is a concept that typically arises in the context of programming languages, particularly in functional programming and lambda calculus. It refers to a method of substituting variables in expressions with their corresponding values in a clear and direct manner. This can often involve replacing free variables in an expression with their bound counterparts or specific values as part of an evaluation process.
In the context of term rewriting systems (TRS), orthogonality is a property that ensures certain desirable features in the behavior of rewrite rules. A term rewriting system consists of a set of rules for transforming terms, which are expressions made up of variables, constants, and function symbols. A TRS is said to be orthogonal if it satisfies the following conditions: 1. **No Overlap**: There is no overlap between the left-hand sides of the rewrite rules.
Amy J. Devitt is an American philosopher known for her work in the fields of philosophy of language, linguistics, and literary theory.

The term "orator" generally refers to a person who is skilled in public speaking and able to deliver speeches effectively and eloquently. An orator can convey ideas, persuade audiences, and evoke emotions through their rhetoric and presentation style. This term is often associated with historical figures like Cicero or Demosthenes, who are celebrated for their oratorical skills.
Murphy's Law is a popular adage that states, "Anything that can go wrong will go wrong." It emphasizes the idea that if something has the potential to go wrong, it is likely to do so at the most inconvenient time. The phrase is often used humorously to express the inevitability of unexpected problems or setbacks in various situations, particularly in engineering, project management, and everyday life. It serves as a reminder to anticipate potential challenges and to plan accordingly to mitigate risks.
Open assessment generally refers to evaluative processes that allow for flexibility, transparency, and inclusivity, often emphasizing collaboration and participation. It is commonly used in educational contexts but can also apply to various fields, including performance evaluation, peer assessment, and public policy. Here are some key features of open assessments: 1. **Transparency**: The criteria for assessment are clearly defined and made available to all participants, which helps to ensure fairness and accountability.
The Flood Forecasting Centre (FFC) in the UK is a facility that plays a crucial role in managing flood risks through forecasting and monitoring flood conditions across the country. Established as a partnership between the Environment Agency (EA) and the Met Office, the FFC provides predictions, alerts, and advice regarding potential flooding events.
The year 1987 is significant in the field of robotics for several reasons, primarily due to advancements in research, technology, and the development of notable projects and concepts. 1. **Advancements in Robotics Research**: During the mid-to-late 1980s, there was increasing interest in artificial intelligence and robotics, leading to new algorithms and frameworks for robot movement and perception.

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.
