The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) is an instrument aboard NASA's Mars Reconnaissance Orbiter (MRO), which was launched in August 2005. CRISM is designed to capture high-resolution images of the Martian surface and analyze the mineral composition through spectral imaging.
A filter fluorometer is an analytical instrument used to measure the concentration of fluorescent substances in a sample by detecting the light emitted by those substances after they have been excited by a specific wavelength of light. Fluorometry is based on the principle of fluorescence, where certain molecules absorb light at one wavelength and then re-emit it at a longer wavelength.
The Spectronic 20 is a type of spectrophotometer, a laboratory instrument used to measure the amount of light absorbed by a sample at specific wavelengths. This device is particularly useful in chemistry and biology for analyzing the concentration of solutes in solution by measuring absorbance, which follows Beer-Lambert's law.
A tristimulus colorimeter is an instrument used to measure the color of a surface or an object by quantifying its color components based on the human visual perception model. Tristimulus refers to the fact that the color measurement is based on three primary color components, typically red, green, and blue (RGB). These color components correspond to the three types of cone cells in human eyes that are responsible for color vision.
Bertram Brockhouse (1918-2019) was a Canadian physicist known for his significant contributions to the field of condensed matter physics. He is best recognized for developing techniques in neutron scattering, which are essential for studying the properties of materials at the atomic level. In 1994, Brockhouse was awarded the Nobel Prize in Physics, sharing the honor with Clifford G. Shull, for their work on the development of neutron scattering techniques for the investigation of condensed matter.
Brian Orr could refer to various individuals, but one prominent figure is Brian Orr, the co-founder of the HVAC School, which provides education and training resources for heating, ventilation, and air conditioning professionals. He is known for his contributions to the HVAC industry through online courses, podcasts, and articles aimed at helping technicians improve their skills and knowledge.
August Hagenbach was a notable Swiss painter born in 1820 and passed away in 1869. He is known for his contributions to the German Romantic movement, particularly in landscape painting. Hagenbach's work often features evocative depictions of nature and the Swiss countryside, characterized by a strong sense of atmosphere and emotion. His paintings have been appreciated for their artistic depth and technique, often blending realism with romantic idealism.
Thomas M. Baer is a prominent figure primarily known for his contributions in the field of optics and his work in the development of advanced laser technologies. He may be recognized for his role as the Director of the Stanford Photonics Research Center and for various academic and industry contributions related to physics and engineering. If you have a specific context or detail about Thomas M.
David Rank is a name that may refer to various individuals or entities, but without specific context, it's challenging to provide a precise answer. One prominent figure associated with the name is David Rank, a former U.S. diplomat who served as the Deputy Chief of Mission at the U.S. Embassy in Nepal. He is known for his views on U.S. foreign policy and his advocacy for civil rights and democracy. If you were referring to a different David Rank or a specific context (e.g.
Hrvoje Petek is a notable physicist, particularly recognized for his work in the fields of experimental condensed matter physics and materials science. He has made significant contributions to the understanding of the electronic properties of materials, particularly using techniques such as laser spectroscopy and electron microscopy. Throughout his career, Petek has been involved in researching topics such as ultrafast phenomena in solids and the development of novel materials with unique properties.
Richard McLean Badger is an artist known for his unique contributions in the field of contemporary art. He often engages with themes related to identity, nature, and the human experience through his work. He employs a variety of mediums, including painting and mixed media, to explore these themes.
John J. Hopfield is an American physicist and a prominent figure known for his contributions to the fields of biophysics and spectroscopy. His work has encompassed various areas, including the development of theoretical frameworks and experimental techniques that enhance our understanding of molecular interactions and dynamics through spectroscopic methods. Hopfield's research has contributed significantly to the understanding of how biomolecules interact with light and how these interactions can be used to probe molecular structures and dynamics.
Feynman slash notation is a shorthand used primarily in quantum field theory to simplify the expressions involving Dirac spinors and gamma matrices. It is named after physicist Richard Feynman, who contributed significantly to the development of quantum electrodynamics and other areas of physics. In this notation, the slash is used to denote a contraction between a four-vector and the gamma matrices that appear in the Dirac equation.
A Killing spinor is a specific type of spinor field that arises in the context of differential geometry and theoretical physics, particularly in the study of Riemannian and Lorentzian manifolds. Killing spinors generalize the notion of Killing vectors, which are associated with symmetries of a manifold.
Orientation entanglement refers to a form of entanglement in quantum systems where the orientation or spatial arrangement of quantum states plays a critical role in the correlations between entangled particles. While most commonly discussing entanglement in terms of properties like spin or polarization, orientation entanglement emphasizes how the geometric arrangement or relative orientation of systems can influence their quantum states and the correlations observed between them.
As of my last knowledge update in October 2023, I don't have specific information on an individual named Matthew Pothen Thekaekara. It's possible he is a private individual, a public figure, or someone who has emerged after that date.
As of my last update in October 2023, Munira Khalil does not appear to be a widely recognized public figure, concept, or term in major contexts like politics, literature, science, or culture. It's possible that she could be a notable individual in a specific community or field, but there may not be significant information available about her on broad platforms.
Norman Lockyer (1836-1920) was a prominent British astronomer and physicist, best known for his pioneering work in the field of astrophysics. He is most famous for discovering the element helium in 1868, which he identified while studying the solar spectrum during a solar eclipse. Lockyer also made significant contributions to the study of spectral lines and the composition of stars, helping to establish the field of astronomical spectroscopy.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
