The Landau-Placzek ratio is a term used in the field of scattering theory, particularly in the context of neutron scattering and other types of spectroscopy. It describes the relationship between the scattering cross-sections of different mechanisms involved in a scattering process. Specifically, the Landau-Placzek ratio is defined as the ratio of the coherent and incoherent contributions to the total scattering. In the context of neutron scattering, these contributions arise from the different ways neutrons interact with a sample.

She is often involved in research that applies physics to understand natural systems, including seismic activity and the properties of geological materials.
The Law of Identity is a fundamental principle in classical logic and philosophy, often expressed succinctly as "A is A." This means that an object is identical to itself and that it possesses all the properties that define it. In other words, for any entity or proposition, it is identical to itself and distinct from any other entity or proposition. The Law of Identity can be formally stated as: - If something is true (or holds), then it is true (or holds).

The list of minor planets designated from 473001 to 474000 includes a series of celestial bodies that are part of the asteroid belt or other regions of the solar system. Each minor planet is assigned a unique number and frequently bears a name or designation based on various conventions (e.g., mythological figures, scientists, etc.).
The list of minor planets numbered 524001 to 525000 includes various small celestial bodies in our solar system that have been cataloged by the Minor Planet Center. These minor planets can include asteroids, trans-Neptunian objects, and other small bodies. Each noted number corresponds to a specific minor planet, which may be identified by its numerical designation and occasionally by a name.
The "List of minor planets: 64001–65000" refers to a range of designated minor planets (also known as asteroids) that have been numbered by the International Astronomical Union (IAU). Minor planets are small celestial bodies that orbit the Sun and are neither planets nor comets. The list contains their respective designations, discoveries, and other relevant information.
The list of minor planets numbered from 86001 to 87000 consists of a series of celestial objects that orbit the Sun and are classified as minor planets (or asteroids). These minor planets are assigned a unique number once they have been confirmed and their orbits determined.
The "List of unnumbered minor planets: 1996" refers to a collection of minor planets (also known as asteroids) that were discovered in the year 1996 but had not yet been assigned a permanent number by the International Astronomical Union (IAU). Minor planets receive a numerical designation after sufficient observation to confirm their orbits.
Formalism is a philosophy of mathematics that emphasizes the role of formal systems and symbolic manipulation in mathematical reasoning. It asserts that mathematics is not about the meaning of mathematical objects or concepts but rather about the manipulation of symbols according to prescribed rules. Here are some key points about formalism in the philosophy of mathematics: 1. **Symbols and Rules**: In formalism, mathematical statements and proofs are seen as strings of symbols that can be manipulated according to specific syntactical rules.
Quasiperiodic tiling refers to a type of tiling of a plane that exhibits order without periodicity. This means that while the pattern does not repeat itself at regular intervals (as it would in periodic tiling), it still has a structured arrangement that follows certain mathematical rules. One of the most famous examples of quasiperiodic tiling is the Penrose tiling, discovered by mathematician Roger Penrose in the 1970s.
John Winthrop (1588–1649) was an English Puritan lawyer and a leading figure in the founding of the Massachusetts Bay Colony. While he is primarily known as a political leader and governor, he also made contributions to education, particularly in the context of the Puritan emphasis on literacy and moral instruction.

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.
