A Special Marine Warning (SMW) is a type of weather advisory issued by meteorological services to inform mariners about potentially hazardous conditions that may affect marine activities. These conditions can include severe weather phenomena such as thunderstorms, waterspouts, high winds, heavy seas, or other marine hazards that are imminent or occurring. The main purpose of an SMW is to alert boaters and vessels in the affected area so they can take appropriate precautions to ensure their safety.
"Straight and Crooked Thinking" is a concept introduced by the British philosopher and author Robert H. Thouless in his 1930 book of the same name. In this work, Thouless explores the different ways people can think about problems and arguments, distinguishing between "straight thinking," which he describes as logical, rational, and clear, and "crooked thinking," which involves fallacies, emotional reasoning, and misleading arguments.
SIR proteins, or Silent Information Regulators, refer to a family of proteins that play a crucial role in the regulation of gene expression, particularly in the context of silencing specific genomic regions. These proteins are most well-studied in the model organism *Saccharomyces cerevisiae*, or baker's yeast, where they are involved in the formation of heterochromatin and the maintenance of epigenetic states.
Sixth Normal Form (6NF) is a stage in the normalization process of database design that deals primarily with temporal data—data that changes over time. The purpose of 6NF is to further reduce redundancy and improve data integrity, especially in situations where data is subject to various types of temporal changes.
The Zhubov scale, sometimes referred to as the Zhubov's scale of severity, is a metric used in meteorology and climatology, primarily in Russia and some Eastern European countries. It is designed to quantify the severity of meteorological conditions, especially in relation to cold weather and its potential effects on human activity, infrastructure, and agriculture.
System Information Modeling (SIM) refers to a process and methodology focused on the representation, analysis, and management of complex systems, including their components, interactions, and data flows. Similar to Building Information Modeling (BIM) in architecture and construction, SIM creates a comprehensive digital representation of a system, integrating both physical and functional aspects.
The Busemann–Petty problem is a classic question in the field of convex geometry. It asks whether, in Euclidean space, the volume of a convex body can be deduced solely from the volumes of its orthogonal projections onto a hyperplane. More specifically, if two convex bodies have the same volume for all orthogonal projections, do they necessarily have to be congruent (that is, identical up to rigid motion)?
The Calgary Corpus refers to a collection of linguistic data that was originally compiled for research purposes, particularly in the field of linguistics and sociolinguistics. It typically contains samples of spoken and written language, which researchers analyze to study language use, variation, and change within different communities or contexts. One notable example is the Calgary English Language Corpus, which focuses on the English spoken in Calgary, Canada.
The California Mathematics Project (CMP) is an educational initiative designed to enhance mathematics education across California. It typically encompasses collaborative efforts among educators, researchers, and mathematicians to improve the teaching and learning of mathematics in K-12 schools. The CMP focuses on several key areas: 1. **Curriculum Development**: The project works on developing and implementing effective mathematics curricula that align with state standards and frameworks.
Zinc oxide is a chemical compound that consists of zinc and oxygen, with the formula ZnO. It is a white powder that is odorless and insoluble in water. Zinc oxide has several important properties and applications: 1. **Physical Properties**: Zinc oxide can appear as a white solid or a powder. It has a melting point of about 1,975 °C (3,587 °F) and is known for its high thermal conductivity and low expansion coefficient.
The California State Railroad Museum (CSRM) is located in Sacramento, California, and is one of the largest and most celebrated railroad museums in the United States. Established to showcase the role of railroads in California's history and development, the museum features a vast collection of locomotives, rolling stock, and railroad artifacts. Visitors can explore beautifully restored trains, learn about the history of railroads in California, and understand their impact on the state's economy and transportation system.
Christ Community Church is a name that can refer to various Christian congregations worldwide, as many churches adopt similar names. Generally, these churches are part of the evangelical tradition and emphasize community involvement, spiritual growth, worship, and outreach. One notable example is Christ Community Church in Olathe, Kansas, which is a large evangelical church that offers a variety of services, programs, and outreach initiatives for its congregation and the surrounding community.
The "Canadian Internet Handbook" typically refers to a resource or guide that provides information about navigating the internet in Canada. It may cover various topics such as internet safety, privacy, digital citizenship, online resources, and tools that are relevant to Canadians. Depending on the specific edition or context, it might also include information about internet policies in Canada, the landscape of internet service providers, and tips for using digital tools effectively and responsibly.
Vacuum energy refers to the underlying energy present in empty space, or "vacuum." In quantum field theory, even in a perfect vacuum devoid of matter, there are still fluctuations due to the Heisenberg uncertainty principle. These oscillations happen because pairs of virtual particles can spontaneously form and annihilate within very short time periods.
The term "vertex function" can refer to different concepts based on the context in which it is used, particularly in mathematics, computer graphics, and physics. Here are some common interpretations: 1. **Graph Theory**: In graph theory, a "vertex function" may refer to a function that assigns values or properties to the vertices (or nodes) of a graph.
Quaternary structure refers to the highest level of protein organization. It involves the assembly of multiple polypeptide chains, known as subunits, that come together to form a functional protein complex. Each subunit in a quaternary structure can be identical or different, and the interactions between these subunits are crucial for the protein's overall functionality. The interactions that stabilize quaternary structures include hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges.
The protests against SOPA (Stop Online Piracy Act) and PIPA (Protect IP Act) were significant events that took place in early 2012 in response to proposed legislation in the United States aimed at combating online copyright infringement. **Background:** - **SOPA:** Introduced in the House of Representatives, SOPA aimed to give copyright holders the ability to take down infringing content and block access to foreign websites that hosted or linked to pirated content.
Canwarn, or the Canadian Weather Amateur Radio Network, is a program in Canada that involves amateur radio operators who help to monitor and report severe weather conditions. This initiative is primarily aimed at enhancing public safety by providing timely information about severe weather events such as thunderstorms, tornadoes, and floods.
Capacity-achieving codes are a class of error-correcting codes that can theoretically approach the maximum possible efficiency for data transmission over a noisy communication channel. The term "capacity" refers to the channel capacity, which is the maximum rate at which information can be transmitted over a communication channel with an arbitrarily low probability of error, as defined by Shannon's channel capacity theorem.
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.Figure 1. Screenshot of the "Derivative" topic page.
