Corona poling is a technique used in the field of polymer science and materials engineering to align the dipoles of certain materials, particularly ferroelectric and piezoelectric polymers. This process is typically performed in the presence of a high electric field and is often conducted in an environment where a corona discharge is generated.
In optical mineralogy, "extinction" refers to the phenomenon observed when a polarized light beam interacts with a mineral grain in a thin section under a microscope. It describes the behavior of light as it passes through a mineral when it is aligned in certain orientations relative to the polarizers. When observing a mineral under crossed polarizers, extinction occurs when the mineral is oriented in such a way that no light is transmitted through the mineral.
Kinoform is a type of phase plate used in optics to modify the phase of light waves passing through it. The term is derived from the German word "Kino," referring to cinema or motion pictures, and "form," indicating the shape or structure. Kinoforms are typically used in applications like diffractive optics, where they help create specific light patterns or focus light in desired ways.
Optics Express is a peer-reviewed scientific journal that publishes research articles in the field of optics and photonics.

The Austin Model 1, often referred to simply as the Austin 1, is a car that was produced by the British automotive manufacturer Austin. It was part of the Austin Mini family, known for its compact size and distinctive design. The Mini was conceived in the late 1950s and aimed to provide an economical and efficient vehicle for urban driving. The Austin 1 was designed to be a small car with a front-wheel-drive layout, which allowed for a spacious interior despite its small footprint.
NDDO can refer to several things, depending on the context. However, the most common references are: 1. **NDDO (National Digital Data Outlet)**: This may refer to platforms or organizations that provide access to digital data related to various fields, such as health, education, or environmental information. 2. **Network Data Distribution Object**: In computer science, this term might relate to frameworks or protocols used in data distribution across networked systems.
Free Induction Decay (FID) is a phenomenon observed in nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). It refers to the signal that is detected after the initial excitation pulse is applied to a sample containing nuclei with magnetic properties, such as hydrogen atoms in water.
Current in the context of fluid dynamics refers to the flow of a fluid, which can be a liquid or a gas. It describes the movement of fluid in a specific direction and can be quantified in terms of velocity, which is the speed of the fluid along with its direction. Fluid currents can occur in various environments, such as: 1. **Water Currents:** These occur in rivers, oceans, and lakes, where water flows due to gravity, wind, and differences in temperature or salinity.
The term "effusive limit" usually pertains to the context of volcanic activity. It refers to the boundary or threshold at which magma begins to flow out of a volcano in a relatively non-explosive manner, resulting in an effusive eruption. These eruptions typically produce lava flows instead of explosive ash clouds, and they occur when the viscosity of the magma is low enough to allow it to flow freely.
Ledinegg instability refers to a phenomenon in thermodynamics and fluid mechanics, particularly in the context of two-phase flow systems, such as those found in nuclear reactors. It describes a stability issue that can occur in boiling systems where there is an interaction between the liquid and vapor phases. In systems that experience boiling, the rate at which vapor is generated can influence the temperature and flow characteristics.
A Love wave is a type of surface seismic wave that travels along the Earth's surface and is named after the British mathematician A. E. H. Love, who first described them in the early 20th century. Love waves are characterized by a horizontal shearing motion that occurs in a horizontal plane perpendicular to the direction of wave propagation. Key characteristics of Love waves include: 1. **Motion**: Love waves involve side-to-side motion of the ground.
INT, or 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride, is a chemical compound that is often used in biological and biochemical assays. Specifically, it is commonly employed in cell viability and cytotoxicity assays to evaluate cell metabolism.

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.
