"Globar" can refer to different concepts or entities depending on the context, but it is most commonly known as a type of thermal radiation source used in various scientific and industrial applications. 1. **Globar (Thermal Radiation Source)**: This is a silicon carbide rod that is heated to produce a broad spectrum of infrared radiation. It is often used in spectroscopic applications, such as Fourier-transform infrared spectroscopy (FTIR), where it serves as a stable and consistent source of infrared light.
"Discoveries" by Guillaume Le Gentil is a comprehensive work that is often associated with his role as an astronomer and explorer in the 18th century. Le Gentil is best known for his observations of the transit of Venus, which he attempted to record from various locations around the world. His work contributed to improvements in the understanding of the solar system, particularly in determining the distance between the Earth and the Sun.
Poncelet can refer to different subjects, primarily in mathematics or names associated with historical figures:
Plasmonic nanoparticles are nanoscale particles that can support surface plasmon resonances, which are collective oscillations of free electrons at the surface of a metal in response to incident light. These particles are typically made of noble metals, such as gold, silver, or copper, which exhibit strong plasmonic effects due to their high conductivity and electron mobility.
Radiofrequency Echographic Multi Spectrometry (REMS) is a non-invasive imaging technique used primarily in the medical field for the assessment of tissue characteristics. It combines principles from ultrasound imaging and radiofrequency analysis to provide detailed information about tissue composition, structure, and stiffness. The REMS technique involves transmitting radiofrequency signals into tissues and analyzing the resulting echoes. It can differentiate between various types of tissues based on their physical properties, such as density and elasticity.
Resonance-enhanced multiphoton ionization (REMPI) is a sophisticated spectroscopic technique used to study the electronic structure of molecules and ions. It involves the absorption of multiple photons by a target molecule to achieve ionization, while also utilizing resonance to enhance the efficiency of the process.
The Stark effect is the phenomenon in which the energy levels of atoms and molecules are shifted and split in the presence of an external electric field. This effect is named after the German physicist Johann Stark, who discovered it in 1913. When an external electric field is applied, it interacts with the electric dipole moments of the atoms or molecules.
Spacecraft attitude control refers to the techniques and systems used to manage and control the orientation of a spacecraft in space. The "attitude" of a spacecraft describes its orientation in three-dimensional space, which is crucial for various operations, such as: 1. **Pointing Sensors and Instruments**: Accurate orientation allows spacecraft to direct instruments, antennas, and other equipment towards specific targets, such as Earth, other celestial bodies, or communication satellites.
Angelika van der Linde is not a widely recognized public figure or concept as of my last knowledge update in October 2021. It’s possible that she could be a private individual or a fictional character from a specific context. If she has gained prominence or relevance after that date, I would not have that information. If you can provide more context or specify what area you are referring to (e.g.
Calvin Beale was a prominent American demographer known for his work in rural population studies and the demographic trends affecting rural America. He served as a researcher with the U.S. Department of Agriculture and was a key figure in studying how demographic shifts impact rural communities, particularly issues related to aging populations, migration, and economic change. In his analyses, Beale often highlighted the differences between urban and rural population trends and emphasized the importance of understanding rural dynamics for policy-making and resource allocation.
Ralph A. Bradley is not widely recognized in a specific context, and there may be multiple individuals with that name in various fields. Without more context, it's difficult to provide a relevant answer. If you meant to inquire about a specific Ralph A. Bradley, such as a professional in academia, a business leader, or someone in another domain, please provide additional details to help narrow it down!
As of my last update in October 2023, Ayse Bilgin does not appear to be a widely recognized public figure, event, or concept. It's possible that she could be a private individual or someone who has risen to prominence after that date.
Albufera refers to a coastal lagoon, specifically one located near Valencia, Spain. The Albufera lagoon is a large freshwater lagoon that is separated from the Mediterranean Sea by a narrow strip of land. It is known for its rich biodiversity, rice fields, and as a significant habitat for various bird species. Here are some key features of the Albufera lagoon: 1. **Ecological Importance**: The lagoon is an important wetland and provides a habitat for numerous aquatic and bird species.
The Henyey track, also known as the Henyey-Greenstein phase function, is a mathematical function used in the field of radiative transfer, particularly in the context of light scattering in media such as atmospheric particles, biological tissues, or other scattering materials. The Henyey-Greenstein function describes how light is scattered by particles and is characterized by a single parameter \( g \), which represents the asymmetry of the scattering.
Hořava-Witten theory is a framework in theoretical physics that emerged in the context of string theory and M-theory. Proposed by Petr Hořava and Edward Witten in 1996, the theory seeks to provide a consistent way to construct non-perturbative theories based on M-theory, which is believed to unify all five superstring theories.
Twistor string theory is a theoretical framework that seeks to reconcile aspects of quantum mechanics and general relativity, particularly in the context of string theory and the geometry of spacetime. Developed in the 1990s by mathematicians and physicists, including Roger Penrose, twistor theory originally emerged as a geometric approach to understanding the fundamental nature of space, time, and physical reality.
T-coloring is a concept in graph theory, specifically within the field of graph coloring. It involves assigning colors to the vertices of a graph according to certain rules defined by a template graph \( T \). In a T-coloring, a vertex is colored with a color from a predefined set of colors, and the coloring must respect the structure of the template graph \( T \).
The ATS theorem, also known as the Aharonov–Bohm theorem, is a fundamental result in quantum mechanics that illustrates the importance of electromagnetic potentials in the behavior of charged particles, even in regions where the electric and magnetic fields are zero.
L. Gustave du Pasquier is a notable figure in the field of economics, particularly known for his contributions to the analysis of economic policy and the implications of government decisions on market dynamics. His work often involves the interaction between economic theory and practical government applications, focusing on the effects of regulations, taxation, and public spending on economic performance.

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.
