The Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm designed for finding the ground state energy of a quantum system, particularly useful in quantum chemistry and materials science. VQE combines the strengths of both quantum computing and classical optimization techniques to tackle problems that may be infeasible for classical computers alone.
In mathematics, particularly in the fields of probability theory and statistics, a characteristic function is a tool used to uniquely identify the probability distribution of a random variable. The characteristic function of a random variable is defined as the expected value of the exponential function of the random variable, typically involving a complex variable.
John Tate (1925–2019) was an influential American mathematician known for his work in number theory, particularly in the areas of algebraic K-theory, arithmetic geometry, and the theory of motives. He made significant contributions to the understanding of L-functions and the behavior of various algebraic structures, such as abelian varieties.
Józef Wierusz-Kowalski (1857–1939) was a notable Polish painter, best known for his works depicting animals, rural scenes, and landscapes. He was associated with the realist style and often portrayed scenes from everyday life, emphasizing the connection between humans and animals. His works are characterized by a keen observation of nature and an emotional depth, capturing the essence of his subjects with great skill.
Julius Edgar Lilienfeld (1881–1963) was an influential physicist known for his work in the field of electronics and semiconductor technology. He is best known for his contributions to the development of the field-effect transistor (FET), which is a type of transistor used in electronic circuits. Lilienfeld applied for patents related to the FET in the 1920s, which laid the groundwork for future developments in transistor technology.
Jun Zhu is a physicist known for his research in fields such as condensed matter physics, including studies on quantum materials, nanostructures, and their electronic properties.

The Jurkat–Richert theorem is a result in the field of mathematics, specifically within the context of functional analysis and operator theory. The theorem provides conditions under which certain types of linear operators can be decomposed into simpler components. To be more precise, the Jurkat–Richert theorem typically pertains to the behavior of bounded linear operators on Banach spaces (complete normed vector spaces) and is often discussed in relation to the spectrum of operators and their compactness properties.
Károly Bezdek is a Hungarian mathematician known for his work in various fields including combinatorial geometry and topology. He has made significant contributions to the understanding of geometric configurations, combinatorial structures, and related areas. Bezdek has published numerous research papers and has been involved in mathematical education.
The Kavli Institute for Theoretical Physics (KITP) is a research institution located at the University of California, Santa Barbara. It was established in 1990 and is named after the Norwegian-American entrepreneur Fred Kavli, who provided funding for the institute. The KITP primarily focuses on theoretical physics and aims to promote research and collaboration among scientists in various fields of physics. The institute hosts programs and workshops that bring together researchers from different areas to discuss and work on specific topics in theoretical physics.
Kinematic properties refer to the characteristics of motion of an object without considering the forces that cause the motion. In kinematics, we analyze how objects move in terms of their position, velocity, acceleration, and time. Here are some key kinematic properties: 1. **Displacement**: The change in position of an object. It is a vector quantity, which means it has both magnitude and direction.
Laser Inertial Fusion Energy (LIFE) is a form of nuclear fusion that aims to generate energy by producing conditions suitable for nuclear fusion using high-intensity lasers. This approach is based on the principle of inertial confinement fusion (ICF), where lasers compress and heat nuclear fuel—typically in the form of small pellets made of deuterium and tritium (isotopes of hydrogen).
Documentary films about mathematics explore various aspects of the field, including its history, key figures, applications, and the beauty of mathematical concepts. These documentaries often aim to make mathematics accessible and engaging for a broader audience, showcasing how it impacts everyday life, science, technology, and culture.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
