George C. Pimentel (1922–2007) was an American chemist known for his contributions to the field of chemistry, particularly in molecular spectroscopy and chemical education. He made significant advancements in the study of infrared spectroscopy and played a crucial role in developing new techniques and instruments for analyzing molecular structures. Pimentel was a prominent figure in academia and served on the faculty at the University of California, Berkeley. He was also involved in promoting science education and public understanding of chemistry.
Jean Lecomte could refer to different individuals, particularly because "Lecomte" is a relatively common French surname. One notable figure is Jean Lecomte, a French painter known for his works in the late 19th and early 20th centuries. He was associated with the academic art movement and created various historical and genre paintings.
Richard R. Ernst is a renowned Swiss chemist, best known for his pioneering work in the field of nuclear magnetic resonance (NMR) spectroscopy. He was awarded the Nobel Prize in Chemistry in 1991 for his contributions to the development of NMR spectroscopy, which has become an essential tool in chemistry, biology, and medicine.

"Speech at the Politeama" refers to a notable oration made by Italian composer and conductor Arturo Toscanini. It was delivered at the Politeama Theatre in Palermo, Sicily. Toscanini is renowned for his passionate approach to conducting and his commitment to the integrity of the music he interpreted.
The Pauli exclusion principle is a fundamental principle in quantum mechanics, formulated by physicist Wolfgang Pauli in 1925. It states that no two fermions (particles with half-integer spin, such as electrons, protons, and neutrons) can occupy the same quantum state within a quantum system simultaneously. In the context of atomic structure, this principle explains why electrons in an atom fill available energy levels in a specific way.
The Spin Hall Effect (SHE) is a physical phenomenon observed in certain materials, particularly in solid-state systems, where a transverse spin current is generated in response to an applied electric field. Unlike the conventional Hall effect, which produces a charge current that flows parallel to the applied electric field and results in a transverse voltage due to charge carriers deflecting, the Spin Hall Effect is concerned with the generation of spin polarization rather than charge separation.
Ballooning instability is a phenomenon primarily observed in magnetically confined plasma, typically in the context of nuclear fusion research, specifically in tokamaks and stellarators. It refers to a type of instability that can arise in plasma due to pressure gradients and magnetic field topology. In a magnetic confinement system, plasma is held in place by magnetic fields, which are designed to keep the charged particles (ions and electrons) from escaping.
Lin Chong scene by Ciro Santilli 40 Updated 2025-07-16
Lance instructor of the 800,000 Imperial Guards (八十万禁军枪棒教头). TODO understand the "枪棒" part: zhidao.baidu.com/question/206659649.html.
The adopted son of Gao Qiu wanted to fuck his wife, and because of this they frame him of planning to take revenge by killing Go Qiu, even though Lin Chong had decided not to take revenge to avoid harming his wife further.
They just keep trying to kill him, until at one point he just gives up and becomes a fugitive.
His story is well told in The Water Margin.
Usually called by others as 林教头 (lin jiaotou, literally Head Instructor Lin, but usually translated as just Instructor Lin).
Issue voting refers to the practice where voters base their electoral choices primarily on specific issues or policy preferences rather than on party affiliation, candidate personality, or other factors. In issue voting, individuals evaluate candidates or parties based on how closely their positions align with the voter's own views on significant topics, such as the economy, healthcare, education, environment, social justice, and foreign policy.
Quadratic voting (QV) is a voting mechanism designed to aggregate preferences more effectively in situations where individuals have varying levels of interest in an issue. Unlike traditional voting methods, where each voter typically gets one vote per issue, quadratic voting allows individuals to express the intensity of their preferences by allocating votes in a way that reflects how strongly they feel about an issue. In quadratic voting, individuals can buy multiple votes for a particular option, but the cost of the votes increases quadratically.
Equatorial waves are oceanic or atmospheric waves that occur in the equatorial regions of the Earth. These waves are characterized by their unique dynamics and properties influenced by the Earth's rotation, the Coriolis force, and the stratification of the atmosphere or ocean. The most notable types of equatorial waves include: 1. **Equatorial Kelvin Waves**: These are eastward-propagating waves influenced by the Coriolis effect and are characterized by their dispersion relation.
The Kelvin wake pattern, also known as the Kelvin wake or Kelvin wave pattern, refers to the specific formation of waves that occurs behind an object moving through a fluid, such as air or water. This phenomenon is named after the British physicist Lord Kelvin, who conducted extensive studies on fluid dynamics. When a body moves at a certain speed through a fluid, it generates a series of wave patterns that extend outward from the object.
Cetyl palmitate is a waxy substance derived from the esterification of cetyl alcohol and palmitic acid. It is commonly used in cosmetics and personal care products as an emollient, thickening agent, and skin-conditioning agent. Its properties help to create a smooth texture in formulations, improve the spreadability of products, and enhance the moisturizing effects on the skin.
Montan wax is a natural wax that is derived from lignite, a precursor to coal. It is primarily composed of long-chain fatty acids and alcohols. Montan wax is obtained by extracting and refining the lignite through processes such as solvent extraction and hydrolysis. This wax is known for its unique properties, including high melting points, resistance to heat and chemicals, and excellent gloss and hardness.
Fermi's interaction refers to the fundamental weak nuclear force that governs the interactions of elementary particles, particularly those involving leptons (like electrons and neutrinos) and quarks. This interaction is largely described within the framework of the electroweak theory, which unifies the electromagnetic force and the weak nuclear force. The term "Fermi interaction" is often associated with Enrico Fermi, who made significant contributions to the understanding of weak interactions in the early 20th century.
The weather events of 2017 were marked by a number of significant phenomena globally. Here are some key highlights: 1. **Hurricanes in the Atlantic**: 2017 was an exceptionally active hurricane season. Notable hurricanes included Hurricane Harvey, which caused devastating flooding in Texas, particularly in Houston; Hurricane Irma, which impacted parts of the Caribbean and Florida; and Hurricane Maria, which severely affected Puerto Rico and other Caribbean islands.
The Valid Time Event Code (VTEC) is a code used primarily by the National Weather Service (NWS) in the United States to indicate the validity period of specific weather warnings, watches, or advisories. It is part of a system to communicate critical weather information effectively, especially during severe weather events. The VTEC consists of a specific format that includes the phenomenon type (e.g., tornado, flood), the area affected, and the start and end times of the event.
Spring weather events refer to various meteorological phenomena that occur during the spring season, typically characterized by changes in temperature, precipitation, and atmospheric conditions. These events can vary significantly depending on the geographical location and climate. Some common spring weather events include: 1. **Rain Showers and Thunderstorms**: Spring is often marked by increased rainfall, which can lead to frequent rain showers and thunderstorms. These can be severe in some areas, producing heavy rain, strong winds, and even hail.
The Farmers' Almanac is a publication that has been in circulation since 1818, known for providing long-range weather forecasts, gardening and planting advice, recipes, and various articles related to rural living and home remedies. It is published annually and is particularly famous for its weather predictions, which are made using a secret formula that takes into account factors such as solar cycles, climatology, and historical weather patterns.

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.
