A villanelle is a specific form of poetry that consists of 19 lines, organized into five tercets (three-line stanzas) followed by a quatrain (four-line stanza). The structure is characterized by its strict rhyme scheme and repetition of certain lines. The rhyme scheme is typically ABA for the tercets and ABAA for the quatrain.
The Fabius function, commonly denoted as \( f \), is a specific example of a continuous but nowhere differentiable function. It is constructed using a recursive process and is often used in the study of fractals and analysis of mathematical functions. The function is defined as follows: 1. Define \( f(0) = 0 \).
A "Patiala peg" is a term used primarily in India to describe a large measure of alcoholic spirits, typically whiskey. The name comes from the city of Patiala in the Indian state of Punjab, which is known for its association with larger drinking measures.
Electrical drawing refers to a type of technical illustration that represents the electrical systems and components within a building, machine, or any other structure. These drawings serve as a critical component in the design, installation, and maintenance of electrical systems. There are several types of electrical drawings, including: 1. **Wiring Diagrams**: Illustrate the connections and wiring paths between electrical components. They show how electrical devices are connected and often indicate the type of wiring used.
As of my last update in October 2023, "Wendy Lou" could refer to various things, depending on the context. It might be a person's name, a business, a brand, or even a character in a story.
Romance, in the context of love, refers to a profound emotional connection and attraction between individuals, often characterized by feelings of affection, passion, and intimacy. It can manifest in various forms, including: 1. **Emotional Connection**: Romance often involves a deep emotional bond, where individuals share their thoughts, feelings, and experiences, fostering a sense of closeness.
Silence can refer to several concepts, depending on the context in which it is used: 1. **Absence of Sound**: In its most literal sense, silence denotes a lack of audible noise. This can be complete quietness or a significant reduction in sound levels, often associated with tranquility or solitude. 2. **Philosophical or Spiritual Concept**: In philosophy and spirituality, silence may be associated with introspection, contemplation, or a state of mindfulness.
Hitchhiking is a method of traveling by obtaining rides from passing vehicles, typically by standing along a road and signaling to drivers. Hitchhikers often extend their thumb or display a sign indicating their desired destination to attract the attention of drivers who may be willing to give them a ride. This practice can be informal and spontaneous, and it relies on the willingness of motorists to pick up passengers.
Štefan Luby is a name that may refer to various individuals, but one notable person associated with that name is a Slovak biochemist known for his contributions to the field of biochemistry and molecular biology.
Arnold Oberschelp does not appear to be a widely recognized name in popular culture, academia, or public life as of my last knowledge update in October 2021. It's possible that Arnold Oberschelp is a private individual, a fictional character, or someone who gained prominence after that date.
Reto Knutti is a prominent climate scientist known for his research in climate change, climate modeling, and the uncertainties associated with climate projections. He is affiliated with ETH Zurich (Swiss Federal Institute of Technology in Zurich), where he has made significant contributions to understanding the mechanisms driving climate change and the potential impacts on global and regional scales. His work often focuses on the analysis of climate models, climate sensitivity, and the evaluation of the risks and uncertainties related to climate change impacts.
The term "chirality" refers to the property of an object being non-superimposable on its mirror image, similar to how left and right hands are mirror images of each other but cannot be perfectly aligned. Chirality plays a significant role in various scientific disciplines, especially in chemistry, biology, and materials science.
Cryptochirality refers to a phenomenon in which a chiral molecule exhibits a particular symmetry that makes it difficult to distinguish between its enantiomers (mirror-image forms) in certain contexts. Chirality is a property of asymmetry where a molecule cannot be superimposed on its mirror image. Typically, chiral molecules exist in two forms that are non-superimposable mirror images of each other, often designated as "left-handed" (S) and "right-handed" (R) configurations.
"Twilight" can refer to several things, depending on the context: 1. **Astronomical Phenomenon**: In astronomy, twilight refers to the time of day when the sun is below the horizon, and there is still enough natural light for low-light activities. It is divided into three phases: civil twilight, nautical twilight, and astronomical twilight, each defined by the position of the sun below the horizon.
Peter Aczel is a mathematician, known primarily for his work in mathematical logic, particularly in the area of set theory. He is also known for his contributions to the field of category theory. He has written various papers and articles on these topics, and he is often associated with the development of concepts in logic and set theory that have influenced both foundational mathematics and philosophical discussions around these areas.
Richard Laver is a political scientist and expert in the field of comparative politics, known for his research in electoral systems, party systems, and political behavior. He has contributed to the understanding of how political parties operate and interact in different electoral contexts.
S2 is a star located in the vicinity of the supermassive black hole at the center of the Milky Way Galaxy, specifically in the region known as Sagittarius A* (Sgr A*). It is an interesting object for astronomers because it has a highly elliptical orbit around the black hole, completing a revolution roughly every 16 years.
Fermions are a class of subatomic particles that follow Fermi-Dirac statistics and obey the Pauli exclusion principle. They are one of the two fundamental categories of particles in quantum mechanics, the other being bosons. Fermions are characterized by having half-integer spin (e.g., 1/2, 3/2, etc.), and they include particles such as electrons, protons, neutrons, and neutrinos.
Dry lubricant is a type of lubricant that provides a slippery surface to reduce friction between moving parts without the use of liquid oils or greases. Instead of relying on a wet substance, dry lubricants typically consist of solid materials, often in powder form, that adhere to surfaces. Common materials used in dry lubricants include: 1. **Graphite**: Known for its excellent lubricating properties, graphite forms a layer that reduces friction.
Nested quotation refers to the practice of including a quotation within another quotation. This often occurs in written texts when a source cites or references another source. The inner quotation is typically marked using a different style of quotation marks or other formatting to distinguish it from the outer quotation.

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.
