Statistical risk refers to the potential for loss or negative outcomes associated with uncertain events and is often quantified using statistical methods. It is a measure of the likelihood and impact of adverse events occurring within a given context, such as finance, insurance, health, or decision-making processes. In practical terms, statistical risk can be defined in several ways, including: 1. **Probability of Adverse Events**: It often involves calculating the probability of specific negative outcomes.
Statistical geography is a subfield of geography that uses statistical methods and techniques to analyze spatial data and understand the relationships between geographical phenomena. It involves the study of the distribution, patterns, and trends of various geographical features and social phenomena, such as population, economic activities, land use, and environmental factors. Key aspects of statistical geography include: 1. **Spatial Data Analysis**: Examining data that have a geographical component, often to identify patterns and relationships over space.
"Syrian astronomers" could refer to various historical and contemporary figures or groups involved in astronomy in Syria. Historically, Syria, particularly during the medieval Islamic Golden Age, was home to notable astronomers who contributed significantly to the field of astronomy. 1. **Historical Context**: In the Islamic Golden Age (8th to 14th centuries), scholars from the region, including Syria, contributed to advancements in various scientific disciplines, including astronomy.
A ligand binding assay is a laboratory technique used to study the interaction between a ligand (a molecule that binds to another molecule, typically a protein) and its target, often a receptor or enzyme. These assays are crucial in drug development and pharmacology as they help to understand the binding affinity, specificity, and kinetics of ligands, which can include small molecules, peptides, or antibodies.
Expressive timing refers to the variations in tempo and rhythm that musicians use to enhance the emotional impact and interpretative depth of a piece of music. Rather than adhering strictly to a metronomic beat, performers may slightly accelerate or decelerate certain passages, emphasize specific notes, or use pauses (fermata) to convey feelings and moods more effectively. This practice can add a personal touch to a performance, allowing the musician to communicate their interpretation of the music more compellingly.
Koomey's Law is an observation regarding the energy efficiency of computing systems, named after the researcher Jonathan Koomey. It posits that the number of computations that can be performed per kilowatt-hour of electricity used by a computing system doubles approximately every 1.5 years. This trend highlights the exponential improvement in the energy efficiency of computer processors and systems over time, reflecting advancements in technology, design, and manufacturing processes.
Mahendra Sūri was a renowned scholar, poet, and author known primarily for his contributions to Prakrit literature and Jain texts. His most notable work is the "Māhavīracarita," which is considered a significant text in Jain literature. The work reflects his mastery of Prakrit language and provides insights into Jain philosophy and ethics.
A SUN workstation refers to a type of computer workstation that was developed and marketed by Sun Microsystems, a company known for its high-performance computing products. SUN workstations were primarily based on the SPARC (Scalable Processor Architecture) architecture and ran the Solaris operating system, which is a version of Unix optimized for Sun hardware. SUN workstations were widely used in scientific, engineering, and enterprise environments due to their advanced hardware capabilities and robust software support.
Spiccato is a bowing technique used in string instrument playing, particularly for the violin, viola, cello, and double bass. It involves the bow being bounced lightly on the strings, producing a sharp, distinct sound. This technique allows for a rhythmic articulation of notes, creating a staccato effect while maintaining a level of expressiveness. Spiccato is typically played in the middle of the bow and requires a controlled and relaxed grip to achieve the desired bouncy effect.
Tetsuji Shioda is a notable figure in the world of aikido, a modern Japanese martial art that focuses on harmonious movement and the redirection of an opponent's energy. Born in 1915, Shioda was a direct student of the founder of aikido, Morihei Ueshiba.
Saudi Arabian physicists are scientists from Saudi Arabia who specialize in the field of physics. They can work in various areas such as theoretical physics, experimental physics, condensed matter physics, astrophysics, and many other sub-disciplines. The kingdom has invested significantly in education and research, leading to the development of institutions such as King Abdullah University of Science and Technology (KAUST) and King Saud University, which have contributed to advancements in various scientific fields.
Yutaka Yamamoto is a mathematician known for his contributions to the field of mathematics, particularly in areas such as number theory and algebra. He has been involved in various research projects and has published papers that contribute to the advancement of mathematical knowledge. However, specific details about his work and achievements may vary, as there could be several mathematicians with similar names, and public information about individuals might not be extensively documented.
A Varignon frame, also known as a Varignon parallelogram or Varignon's theorem frame, refers to a specific type of mechanical system used in structural engineering and physics. It involves a rectangular frame formed by four points connected by rigid bars. The essential characteristic of a Varignon frame is that it allows for the application of forces at any of its corners.
WordNet by Ciro Santilli 40 Updated 2025-07-16
Groups concepts by hyponymy and hypernymy and meronymy and holonymy. That actually makes a lot of sense! TODO: is there a clear separation between hyponymy and meronymy?
Browse: wordnetweb.princeton.edu/perl/webwn Appears dead as of 2025 lol.
The online version of WordNet has been deprecated and is no longer available.
Does not contain intermediat scientific terms, only very common ones, e.g. no mention, of "Josephson effect", "photoelectric effect"

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
