In piping and plumbing, "gooseneck" refers to a type of pipe or fitting that has a specific curved shape resembling the neck of a goose. This design is typically characterized by a U-shaped or S-shaped bend, allowing for the transition of flow direction or elevation gain while maintaining a smooth flow path.
A Fermi gas is a theoretical model used in quantum mechanics to describe a collection of fermions, which are particles that follow Fermi-Dirac statistics. Fermions include particles such as electrons, protons, and neutrons, each of which obeys the Pauli exclusion principle. This principle states that no two fermions can occupy the same quantum state simultaneously.
A list of rogue waves refers to documented instances or types of rogue waves, which are large, unexpected, and suddenly appearing ocean waves that can be incredibly dangerous. These waves are often defined as waves that are at least twice the height of surrounding waves and can occur in deep water as well as coastal areas. Rogue waves are also sometimes referred to by other names, such as "freak waves," "king waves," or "monster waves.
The South Atlantic Gyre is a large system of circulating ocean currents located in the South Atlantic Ocean. It is part of the global ocean circulation system and plays a significant role in oceanic and atmospheric processes. The gyre is characterized by a clockwise rotation in the Southern Hemisphere and is primarily formed by the interaction of several major currents, including: 1. **Brazil Current**: This warm current flows southward along the eastern coast of South America.
A Hefner lamp is a type of measurement device used to determine the luminosity or brightness of a light source, specifically in terms of its equivalent light output. Named after the physicist Robert Hefner, the lamp is used primarily in the field of photometry, which is the science of measuring visible light in terms of its perceived brightness to the human eye. The Hefner lamp contains a specific type of candle that provides a consistent and reproducible light output.
Pitch in music refers to the perceived frequency of a sound, which determines how high or low a note sounds. It is a fundamental characteristic of musical notes and is crucial for the creation of melodies and harmonies. Pitch is typically measured in Hertz (Hz), which represents the number of vibrations or cycles per second. For example, the standard pitch for the note A4 (the A above middle C) is set at 440 Hz.
Samarium-neodymium dating is a radiometric dating method used to determine the age of rocks and minerals, particularly those containing rare earth elements. This technique is based on the decay of the isotope samarium-147 (Sm) to neodymium-143 (Nd). Here's how it works: 1. **Decay Process**: Samarium-147 has a half-life of about 106 billion years.
Pediatric radiology is a specialized branch of medicine that focuses on the imaging and diagnosis of diseases and conditions in infants, children, and adolescents. It involves the use of various imaging techniques, including: 1. **X-rays**: Used to visualize the bones and detect fractures, infections, or congenital conditions. 2. **Ultrasound**: A non-invasive method that uses sound waves to create images of soft tissues and organs.
Bohumil Bydžovský is a notable Czech personality, particularly recognized as a figure in the field of mycology, which is the study of fungi. While less widely known than some other scientists, he has contributed to the understanding of fungal classification and biology. However, specific details about his life and work may not be as widely documented or accessible.
Danish women mathematicians have made significant contributions to the field of mathematics, despite historically facing various challenges in a predominantly male-dominated field. Some notable Danish women mathematicians include: 1. **Kirsten B. A. F. Schou** - Known for her contributions in the areas of analysis and mathematical modeling. 2. **Signe H. M. B. Høyer** - A researcher with a focus on mathematical physics and statistical modeling.
Edith de Leeuw is a name that may refer to various individuals, but it is most commonly associated with a Dutch mathematician known for her work in the fields of logic and computer science.
It seems there might be a mix-up with the term "Anna Cartan." It's possible you meant "Cartan," which could refer to Élie Cartan, a French mathematician known for his work in differential geometry and Lie theory. Cartan developed several important concepts and theorems in mathematics, particularly in the areas of differential forms and symmetric spaces. If "Anna Cartan" refers to something specific or a different context (such as a fictional character, a contemporary figure, etc.
Bertrand Toën is a mathematician known for his work in the field of algebraic geometry and derived categories. He has contributed significantly to the development of modern mathematical concepts and theories, particularly related to the study of algebraic structures, and has published various papers and articles in these areas. His work often involves advanced topics such as moduli spaces, homotopy theory, and the relationships between geometry and other branches of mathematics.
It seems there might be a misunderstanding or confusion regarding "Jules Molk." As of my last knowledge update in October 2023, there is no widely recognized person, brand, or concept by that name. It's possible that it could refer to a less-known individual, a fictional character, or a term that has emerged after my last update.
Mariette Yvinec is not widely recognized in mainstream contexts, and there may be limited information available on this name. It is possible that she could be a private individual or have relevance in specific fields like academia, literature, or niche interests. If you provide more context or specify the domain in which she is associated (such as art, science, etc.
Éric Moulines is a French statistician known for his work in the fields of econometrics and time series analysis. He has contributed to various areas of statistics, including nonlinear time series models and the theory of statistical inference. Moulines has published numerous papers in academic journals and is recognized for his contributions to the development of statistical methodologies.
Medieval Iranian mathematicians played a significant role in the development of mathematics during the Islamic Golden Age, which roughly spanned from the 8th to the 14th centuries. This period was marked by a flourishing of knowledge across various fields, including mathematics, astronomy, medicine, and philosophy, as scholars in the Islamic world, including those in Iran, translated and built upon ancient Greek, Indian, and Persian texts.
Hillel Furstenberg is a renowned mathematician known for his contributions to various fields of mathematics, including ergodic theory, arithmetic dynamics, and number theory. He was born on July 29, 1935, in Berlin, Germany, and later emigrated to the United States. Furstenberg is particularly recognized for his work on the structure of dynamical systems and his innovative use of probabilistic methods in number theory.

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.
