In physics, deflection refers to the displacement of a body or a beam from its original position under the influence of an external force. When an object is subjected to forces such as tension, compression, bending, or torsion, it can deform or bend, resulting in a change in its shape or position. Deflection is often measured as the distance that a point on the structure moves from its equilibrium position.
1:32 scale refers to a scale ratio commonly used in modeling and miniatures, where 1 unit of measurement on the model (e.g., an inch or a centimeter) represents 32 units of the same measurement in real life. This means that a model at 1:32 scale is 32 times smaller than the actual object it represents.
A 1:64 scale means that one unit of measurement (such as an inch, centimeter, or meter) on a model or representation is equivalent to 64 of the same units in real life. For example, if a model car is designed at a 1:64 scale, it would be 1/64th the size of the actual car.
1:72 scale is a scale model ratio that indicates that one unit of measurement on the model represents 72 of the same units in reality. This means that an object modeled in this scale is 1/72nd the size of the actual object. For example, if a model airplane in 1:72 scale is 10 inches long, the real airplane would be 720 inches (or 60 feet) long.
Scattering, absorption, and radiative transfer are fundamental concepts in optics that describe how light interacts with matter. Here's a brief overview of each concept: ### Scattering Scattering refers to the deflection of light rays from a straight path due to interaction with particles or irregularities in a medium. When light encounters small particles (like dust, air molecules, or water droplets), it can be redirected in various directions.
Core-excited shape resonance is a phenomenon observed in the field of quantum mechanics and atomic physics, particularly in the context of electron scattering and the interaction of charged particles with matter. Here’s a summary of the key concepts involved: 1. **Shape Resonance**: This term generally refers to a type of resonance that occurs when an incoming particle experiences a potential barrier and the shape of the potential allows for the temporary trapping of the particle, leading to an enhancement of scattering processes.
Grazing-incidence small-angle scattering (GISAS) is a powerful experimental technique primarily used in materials science, physics, and biophysics to study thin films, nanostructures, and surfaces. It combines aspects of small-angle scattering (SAS) and grazing incidence techniques to provide valuable information about the structural properties of materials at the nanoscale.
Lattice scattering refers to the phenomenon where a particle, such as an electron or phonon, interacts with the regular periodic structure of a crystal lattice. This process is crucial in solid-state physics and materials science because it affects various properties of materials, including electrical conductivity, thermal conductivity, and the behavior of electrons in semiconductors. In more detail, in a crystalline solid, atoms are arranged in a repetitive pattern, forming a lattice.

The primary goal of this network is to provide real-time data and analyses regarding earthquakes and seismic events, which is vital for disaster preparedness and response efforts.
A neutron moisture gauge is an instrument used to measure the moisture content in soil, concrete, and other materials. It operates based on the principles of nuclear physics, specifically by utilizing low-energy neutrons to interact with hydrogen atoms found in water. ### How It Works: 1. **Source of Neutrons**: The gauge contains a radioactive source, typically americium-beryllium, that emits neutrons.
Turbidimetry is an analytical technique used to measure the cloudiness or turbidity of a liquid caused by the presence of suspended particles. It involves the assessment of how much light is scattered by particles in the solution when a beam of light passes through it. The more particles present, the higher the turbidity, which results in a greater scattering of light.
"Mathematicians by academic institution" typically refers to the classification or listing of mathematicians based on their affiliations with particular universities or research institutes. This can include well-known mathematicians who held positions at specific institutions, as well as current faculty members at universities renowned for their mathematics programs. For example, several prestigious academic institutions are known for their contributions to mathematics: 1. **Princeton University** - Home to many notable mathematicians, especially in fields like number theory and geometry.

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.
