The Local-Density Approximation (LDA) is an approach used in the field of density functional theory (DFT) to approximate the exchange-correlation energy of a many-electron system. In LDA, it is assumed that the exchange-correlation energy at a point in space is a function of the electron density at that same point. This means that the approximation relies on the idea that the behavior of the system can be described by the properties of an electron gas with uniform density.
Coorbit theory is a mathematical framework used in the analysis of functions and signals, particularly in the context of time-frequency analysis and wavelet theory. It is primarily concerned with the study of function spaces and how they interact with various transforms, such as the Fourier transform and wavelet transforms.
The Hellinger–Toeplitz theorem is a result in functional analysis that characterizes certain types of operators, specifically compact operators on Hilbert spaces. It states that if \( T \) is a compact linear operator on a Hilbert space \( H \), then the following conditions are equivalent: 1. \( T \) is a compact operator. 2. The image under \( T \) of the unit ball in \( H \) is relatively compact in \( H \) (i.
The term "singular trace" can refer to several concepts depending on the context, primarily in mathematics and certain applied fields. Here are a few interpretations: 1. **Mathematical Context**: In linear algebra or functional analysis, the trace of a matrix is the sum of its diagonal elements. A "singular trace" might refer to the trace of a singular matrix (a matrix that is not invertible).
"Lu Jeu Sham" refers to a traditional form of Chinese therapeutic massage and bodywork, often associated with the principles of Traditional Chinese Medicine (TCM). It combines elements of acupressure, stretching, and manipulation to promote relaxation, relieve pain, and enhance overall well-being. Practitioners of Lu Jeu Sham may focus on energy points along the body’s meridians to restore balance and alleviate various ailments.
"Southland Tales" is a 2006 science fiction film written and directed by Richard Kelly, who is also known for his earlier film "Donnie Darko." The movie is set in a dystopian version of Los Angeles in the near future, specifically in the year 2008, and it explores themes of war, government surveillance, and the nature of reality through its complex narrative.
CHRNE refers to the "Code for Human Rights and Non-Discrimination in Education." It is often associated with efforts to promote and protect human rights and non-discrimination principles in educational settings. The initiative emphasizes the importance of ensuring access to education for all individuals, regardless of their background, identity, or circumstances.
The Haldane–Shastry model is an important theoretical model in condensed matter physics, particularly in the study of quantum magnetism and lattice systems. Named after physicists F.D.M. Haldane and B.S. Shastry, who contributed to its development, the model describes a one-dimensional system of spin-1/2 particles arranged on a lattice with specific interactions.

The dihydrogen cation, often denoted as \( \text{H}_2^+ \), is a molecular ion consisting of two hydrogen atoms with an overall positive charge. It is formed when one of the electrons in a neutral hydrogen molecule (\( \text{H}_2 \)) is removed, resulting in a species that lacks one electron but still has two protons.
A "particle in a ring" is a fundamental problem in quantum mechanics that describes a quantum particle constrained to move on the circumference of a circle (or ring) of a fixed radius. This model is significant for understanding certain concepts in quantum mechanics, such as quantization, angular momentum, and the behavior of particles in systems with circular symmetry.
Spin-1/2 is a fundamental concept in quantum mechanics that describes a type of intrinsic angular momentum possessed by certain elementary particles, such as electrons, protons, and neutrons. The term "spin" refers to a property of particles that is analogous to classical angular momentum but does not correspond to any physical spinning motion in space. In quantum mechanics, particles are characterized by their spin quantum number \( s \), which defines their spin magnitude.
As of my last knowledge update in October 2023, "DNA teleportation" is not a scientifically recognized term or concept in the field of genetics or physics. However, the concept of "teleportation" is often associated with quantum mechanics, particularly quantum teleportation, which involves the transfer of quantum information between particles at a distance without moving the particles themselves.
"The Power" is a self-help book written by Rhonda Byrne, published in 2010. It is a follow-up to her earlier book, "The Secret," which focuses on the law of attraction and the idea that positive thinking can manifest one's desires and improve one's life. In "The Power," Byrne emphasizes the importance of love as a fundamental force in achieving personal fulfillment and success.
Lasers are devices that emit light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" is an acronym for "Light Amplification by Stimulated Emission of Radiation." ### Key Characteristics of Lasers: 1. **Coherence**: Laser light is highly coherent, meaning that the light waves are in phase in both time and space. This quality allows lasers to produce focused beams of light over long distances.

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.
