Atmospheric sounding is a technique used to measure and analyze the vertical profile of atmospheric variables, such as temperature, humidity, and pressure, throughout the atmosphere. This process provides critical data that helps meteorologists and scientists understand weather patterns, climate variations, and atmospheric conditions. There are several methods and instruments used for atmospheric sounding, including: 1. **Weather Balloons (Radiosondes)**: A common method involving the release of balloons that carry instruments (radiosondes) into the atmosphere.
Boundary layer meteorology is a specialized field of meteorology that focuses on the atmospheric boundary layer (ABL), which is the lowest part of the Earth's atmosphere. This region extends from the surface up to a few kilometers above ground level and is directly influenced by the Earth's surface and its characteristics, such as land use, vegetation, topography, and temperature.
An electron shell is a grouping of electrons within an atom that have similar energy levels and are located at a certain distance from the nucleus. These shells are defined by quantum mechanics and are an important aspect of atomic structure. ### Key Points about Electron Shells: 1. **Energy Levels**: Electrons are arranged in shells around the nucleus, each with a specific energy level. The shells are designated by principal quantum numbers (n = 1, 2, 3, etc.
"Narrows" can refer to several different concepts depending on the context. Here are a few possibilities: 1. **Geographical Feature**: In geography, a "narrow" can refer to a narrow water passage, such as a strait or channel that connects two larger bodies of water. 2. **Film and Television**: "The Narrows" is a title that has been used in films and literature.
The inert-pair effect is a phenomenon observed in the chemistry of certain heavy elements, particularly within the p-block of the periodic table. It refers to the tendency of the outermost s electrons of the heavier elements in groups 13 to 16 (especially the thallium, lead, bismuth, and polonium elements) to remain non-bonding or "inert" when these elements form compounds.
Mirror nuclei are pairs of atomic nuclei that have the same total number of nucleons (i.e., the same mass number) but differ in the numbers of protons and neutrons. In essence, one nucleus has more protons while the other has more neutrons. This difference allows for a unique comparison of the nuclear structure and the forces at play within the nuclei. For example, consider the pair of mirror nuclei: carbon-12 (^12C) and boron-12 (^12B).
A photonic molecule is a concept in the field of quantum optics and photonics, where the collective behavior of photons is studied in a way that mimics the properties of traditional molecules. These "molecules" do not consist of atoms in the conventional sense; instead, they are formed by the coupling of photons that are confined in systems such as photonic crystals or optical cavities.
NuMI, which stands for Neutrinos at the Main Injector, is a neutrino beam facility located at Fermilab, a U.S. Department of Energy national laboratory in Batavia, Illinois. The facility is specifically designed to produce and direct a beam of neutrinos for experiments studying their properties, including their mass, oscillations, and interactions. NuMI uses protons accelerated by Fermilab's Main Injector to produce neutrinos through a process called meson decay.
The spin quantum number is a fundamental quantum number that describes the intrinsic angular momentum (or "spin") of a particle, particularly in the context of quantum mechanics and atomic physics. It is denoted by the letter \( s \) or sometimes by \( m_s \) when referring to its projection along a specific axis (usually the z-axis). Key characteristics of the spin quantum number include: 1. **Values**: The spin quantum number can take on half-integer or integer values.
Donald B. Campbell (1920–1996) was an influential American psychologist known for his contributions to the field of social science research methods and psychology. He is best known for his work on the philosophy of science, particularly in relation to the concepts of validity, and he played a crucial role in developing the field of program evaluation. Campbell co-authored the Campbell and Stanley framework for quasi-experimental research designs, which addressed issues of internal and external validity in research.
"Alan Head" does not appear to refer to a widely recognized concept, individual, or term as of my last update in October 2023. It’s possible that you may be referring to something more specific or niche that has emerged since then, or it could be a misspelling or miscommunication regarding a different term or name.
Andrew G. White could refer to a variety of individuals or entities, depending on the context. However, without specific information, it's difficult to pinpoint exactly who or what you're referring to. If you mean a person, it could refer to an academic, professional, or a public figure with that name. If you mean an organization or a company, it could refer to a business or a brand that includes that name.
Hope is a functional programming language that was designed in the early 1980s, primarily by the computer scientist Gordon P. A. S. Morrison and others, at the University of Cambridge. It was created as a research tool to explore concepts related to functional programming, type systems, and polymorphism.
Betty Louise Turtle is a unique and charming character often associated with children's literature, specifically created for educational purposes. She typically embodies traits such as kindness, curiosity, and a love for learning. Often found in stories aimed at teaching values such as friendship, perseverance, and problem-solving, Betty Louise Turtle may also serve as a symbol of slow and steady progress, promoting the idea that taking time can lead to success.
David McClelland is an Australian physicist known for his contributions to the field of gravitational wave detection and astrophysics. He has been significantly involved in projects related to laser interferometry and the detection of gravitational waves, particularly through his work with large-scale observatories such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) and other related experiments.
Denis Evans could refer to different individuals or contexts, depending on what you are looking for. Here are a couple of possibilities: 1. **Denis Evans (Theoretical Physicist)**: An academic with contributions to the field of physics, particularly in statistical mechanics or thermodynamics. However, specific details about his contributions and background would depend on the individual being referred to.

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
