The Equatorial Electrojet (EEJ) is a narrow band of enhanced eastward flowing electric current that occurs in the equatorial region of the Earth's ionosphere, specifically between approximately 1°N and 1°S latitude. This phenomenon is primarily observed in the E-region of the ionosphere, at altitudes ranging from about 100 to 120 kilometers (approximately 62 to 75 miles) above the Earth's surface.
Equisatisfiability is a concept in logic and computer science, particularly within the fields of propositional logic and satisfiability (SAT) problems. Two logical formulas are said to be equisatisfiable if they have the same satisfiability status; that is, if one formula is satisfiable (there exists an assignment of truth values to its variables that makes the formula true), then the other formula is also satisfiable, and vice versa.
Erhard Schmidt can refer to different individuals, but one prominent figure associated with that name is Erhard Schmidt (1868–1959), a German mathematician known for his work in the field of functional analysis and algebra. He made significant contributions to the theory of linear spaces and has been referenced in various mathematical contexts.
A hexagonal number is a figurate number that represents a hexagon. The \(n\)th hexagonal number can be calculated using the formula: \[ H_n = n(2n - 1) \] where \(n\) is a positive integer. Hexagonal numbers can be visualized as a pattern of points arranged in the shape of a hexagon.
Ernest Henry Rutter (1889–1968) was a notable British botanist, particularly recognized for his work in plant physiology and ecology. He made significant contributions to the understanding of plant growth and development and conducted extensive research on the effects of environmental factors on plant life. His work has implications for agriculture, ecology, and conservation.
As of my last knowledge update in October 2021, there is no widely recognized figure, concept, or entity specifically known as "Ernesto Padova." It’s possible that you might be referring to a lesser-known person or a new development that has emerged since then.
Error analysis in mathematics refers to the study of errors in numerical computation and mathematical modeling, focusing on the quantification and management of inaccuracies that arise during calculations and approximations. It involves understanding how errors can propagate through calculations and how to minimize them to ensure more reliable results. There are several types of errors commonly analyzed: 1. **Absolute Error**: The difference between the exact value and the approximate value. It quantifies how far off an approximation is from the true value.
Error Management Theory (EMT) is a psychological framework developed to explain how individuals make decisions in uncertain situations, particularly in the context of social and romantic relationships. The theory posits that humans are evolutionarily predisposed to manage errors in judgment, especially when it comes to evaluating others' romantic interest or fidelity. Key tenets of Error Management Theory include: 1. **Asymmetrical Costs of Errors**: EMT emphasizes that the costs associated with false positives (e.g.
The Estimated Date of Delivery (EDD) refers to the anticipated date when a pregnant woman is expected to give birth. It is typically calculated based on the first day of the woman's last menstrual period (LMP) or using ultrasounds to determine the gestational age of the fetus. The standard gestational period for a full-term pregnancy is about 40 weeks (or approximately 280 days) from the LMP.
"Estonian women physicists" refers to female scientists from Estonia who specialize in physics or have made significant contributions to the field. Estonia has a growing community of women in science, and various individuals have made notable achievements in physics, including research in theoretical physics, experimental physics, and related interdisciplinary areas. While there isn't an exhaustive list of prominent Estonian women physicists, some notable figures may include: 1. **Nina K.
The Ettridge Collection typically refers to a collection of art, objects, or literature that is attributed to or associated with an individual named Ettridge. However, specific information about the Ettridge Collection may vary depending on the context and location in which it is referenced. If you are looking for details about a particular Ettridge Collection, it would help to know more about the context, such as the type of collection (art, literature, historical artifacts, etc.) or the geographical location.
A Euclidean distance matrix is a matrix that captures the pairwise Euclidean distances between a set of points in a multi-dimensional space. Each element of the matrix represents the distance between two points.
Eugene C. Bingham was an American engineer and researcher known for his contributions to the fields of rheology and fluid mechanics. He is often recognized for his work on the behavior of non-Newtonian fluids, which do not follow Newton's law of viscosity. Bingham is particularly associated with the Bingham plastic model, which characterizes materials that behave as a solid until a certain yield stress is applied, after which they flow like a viscous fluid.
Eukaryotic initiation factors (eIFs) are a group of proteins that play essential roles in the initiation phase of protein synthesis (translation) in eukaryotic cells. These factors are involved in various steps of the initiation process, which includes the assembly of the ribosome on the messenger RNA (mRNA), the recruitment of the initiator transfer RNA (tRNA), and the proper positioning of the ribosomal subunits.

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.
