Marie Rognes is a notable figure in the field of applied mathematics and is known for her work in scientific computing, particularly in the areas of numerical methods and simulation. She is affiliated with institutions in Norway, where she has contributed to research related to partial differential equations (PDEs), computational fluid dynamics, and other areas of mathematical modeling.
Doron Levy could refer to multiple individuals, as it is a name that can belong to different people. Without additional context, it's difficult to provide a specific answer. If you are referring to a public figure, an academic, or someone notable in a particular field, please provide more details.
Jan Vondrák could refer to several individuals, but one notable figure is a Czech mathematician, known for his contributions in the fields of combinatorics, computer science, and information theory. He has made significant contributions to the study of error-correcting codes and various areas of discrete mathematics.
Jean Morlet was a French geophysicist and wavelet theory pioneer, best known for his contributions to time-frequency analysis and the development of wavelet transforms. He introduced the concept of wavelets in the early 1980s, which provided a mathematical tool for analyzing signals across different scales and durations. Morlet's work enabled significant advancements in various fields, including signal processing, image analysis, and geophysics, particularly in seismic data interpretation.

One encoding to rule them all, and in the darkness bind them.
Kenneth M. Golden is a notable figure known primarily for his work in applied mathematics, particularly in the fields of mathematical modeling, analysis, and computational methods. He is a professor of mathematics at the University of Utah and has made significant contributions to a variety of applied problems, including those in the fields of fluid dynamics, biology, and materials science.
Peregrina Quintela Estévez is not a widely recognized name, and there may not be notable information available about an individual by that name as of my last knowledge update in October 2023. It's possible that it refers to a private individual or a topic that has emerged more recently.
Wotao Yin is a form of traditional Chinese medicine that emphasizes the practice of Tai Chi and Qigong for health and wellness. The term "Wotao" translates to "my way" or "the way of my body," reflecting a personalized approach to understanding and enhancing one's physical, mental, and spiritual well-being. This practice combines gentle movements, mindfulness, and breathing techniques to cultivate inner peace, balance, and energy flow (Qi or Chi) within the body.
Arm is a company known for its semiconductor and software design, particularly in the area of processor architecture. Their primary solutions revolve around the design of ARM architecture, which is used in a wide range of devices, from smartphones and tablets to embedded systems and IoT (Internet of Things) devices. Arm does not manufacture chips; instead, it licenses its designs to other companies that produce chips based on Arm architecture.
Asteroid spectral types are classifications of asteroids based on their reflectance spectra, which is the way they reflect light across different wavelengths. These spectral types help astronomers understand the composition, surface properties, and origins of asteroids. Different spectral types correspond to different mineralogical and chemical compositions. The most commonly used spectral classifications for asteroids include: 1. **C-type (Carbonaceous)**: These are the most common type, making up about 75% of all known asteroids.
ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) is a project aimed at developing a next-generation nuclear reactor based on sodium-cooled fast reactor (SFR) technology. It is a research and experimental program initiated primarily by France's nuclear research agency, CEA (Commissariat à l'énergie atomique et aux énergies alternatives), to demonstrate the viability of advanced nuclear reactor designs.
Certainly! Here’s a brief overview of some significant astronomers categorized by century: ### Ancient to Medieval (Pre-17th Century) #### 1st Century - **Ptolemy**: An influential Greek astronomer best known for the Almagest, which presented the geocentric model of the universe.
Astrophysical X-ray sources are celestial objects that emit X-rays, a form of high-energy electromagnetic radiation. These sources are found throughout the universe and can vary widely in nature and origin. Some of the main types of astrophysical X-ray sources include: 1. **X-ray Binaries**: These systems consist of a normal star and a compact object such as a black hole or a neutron star. The compact object pulls material from the normal star, forming an accretion disk.
Astrophysics research institutes are scientific organizations or institutions dedicated to the study of astrophysics, which is the branch of astronomy that deals with the physical properties and underlying processes of celestial bodies and the universe as a whole. These institutes typically conduct research, provide educational programs, and promote public outreach and engagement related to the field of astrophysics.
The Atkinson-Mingarelli theorem is a result in the field of differential equations, particularly in the context of boundary value problems for second-order ordinary differential equations (ODEs). It deals with the existence of multiple solutions to certain types of boundary value problems. The theorem essentially states conditions under which a second-order linear differential equation can have multiple solutions based on its boundary conditions and the nature of the functions involved.
Finite Element Exterior Calculus (FEEC) is a mathematical framework that unifies the finite element method (FEM) with the theory of differential forms and exterior calculus. It provides a systematic way to analyze and construct finite element methods for a variety of problems in applied mathematics, physics, and engineering, particularly those described by differential equations of a geometrical or physical nature. ### Key Concepts 1.

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.
