Edward Frankland by Wikipedia Bot 0
Edward Frankland was a notable British chemist, born in 1825 and died in 1899. He is best known for his work in organic chemistry, particularly for his contributions to the understanding of chemical bonds and the development of the concept of valency, which describes how atoms in molecules bond to each other. Frankland's research significantly advanced the field of organic chemistry, and he was also instrumental in establishing the study of coordination compounds.
Edward Henry Whinfield (1828–1883) was a notable English scholar, translator, and academic renowned primarily for his translation of the Persian poet Jalaluddin Rumi's works into English.

Effective action by Wikipedia Bot 0
In theoretical physics, particularly in the context of quantum field theory and statistical mechanics, the concept of "effective action" refers to a functional that encapsulates the dynamics of a system after integrating out (or averaging over) certain degrees of freedom. The effective action is especially useful in situations where one is interested in the long-range or low-energy behavior of a system while neglecting the details of high-energy or short-range components.
Effective field theory (EFT) is a framework in theoretical physics used to describe physical systems at specific energy scales while accounting for the effects of higher energy processes in a systematic way. The main idea behind EFT is that, at a given energy scale, we can ignore the details of physics that occurs at much higher energy scales, focusing instead on the degrees of freedom and interactions relevant to the low-energy behavior of the system.
Tropical cyclones, also known as hurricanes or typhoons depending on their location, can have a wide range of effects on the environment, communities, and economies. Here are some of the primary effects: ### 1. **Wind Damage** - **Destruction of Infrastructure**: High winds can cause significant damage to buildings, bridges, and roads. Power lines can be downed, leading to widespread electricity outages.

TeXworks by Wikipedia Bot 0
TeXworks is an open-source, LaTeX editing application that provides a user-friendly interface for typesetting documents using the TeX typesetting system. It is designed to make it easier for users, especially those who may be new to LaTeX, to create and compile LaTeX documents. Key features of TeXworks include: 1. **Simple Interface**: It offers a clean, minimalistic user interface that reduces complexity, making it accessible for beginners.
Ehrenfest equations describe the time evolution of the average values of position and momentum in quantum mechanics, particularly in the context of the interaction between classical and quantum systems. Named after the physicist Paul Ehrenfest, these equations establish a bridge between classical mechanics and quantum mechanics by showing how certain classical quantities can be derived from quantum mechanical expectations. In a typical setting, consider a quantum system described by a Hamiltonian \( H \).
The Ehrenfeucht–Mycielski sequence is a mathematical construct that originates from the field of combinatorial set theory and is typically studied in the context of discrete mathematics and graph theory. Specifically, it is often related to the study of properties of graphs and their corresponding sequences. The definition of the Ehrenfeucht–Mycielski sequence is connected to the concept of constructing new objects (like graphs or sequences) from existing ones while preserving certain properties.
Einstein's Unfinished Revolution refers to the ongoing efforts in theoretical physics to fully integrate and unify the theories of quantum mechanics and general relativity. This term suggests that while Albert Einstein made revolutionary contributions to our understanding of the universe, specifically through his contributions to relativity and quantum theory, there remain unresolved questions and inconsistencies between these two foundational frameworks. Einstein’s general relativity describes the force of gravity as the curvature of spacetime caused by mass, providing a comprehensive description of large-scale phenomena.

Elastin-like polypeptides (ELPs) are a class of genetically engineered polypeptides that mimic the properties of natural elastin, a key protein in connective tissues known for its elasticity and ability to return to its original shape after stretching. ELPs are composed of repeating peptide sequences typically rich in the amino acids glycine, proline, and valine, which are characteristic of elastin.
Electric vehicle by Wikipedia Bot 0
An electric vehicle (EV) is a type of automobile that is powered entirely or partially by electricity. Unlike conventional vehicles that use internal combustion engines fueled by gasoline or diesel, electric vehicles utilize electric motors for propulsion, which are powered by batteries or, in some cases, fuel cells. There are several types of electric vehicles: 1. **Battery Electric Vehicles (BEVs)**: These are fully electric vehicles that run on batteries alone.
Rainville polynomials are a sequence of orthogonal polynomials that arise in the context of asymptotic analysis and approximations in mathematical physics. They are named after the mathematician Edward D. Rainville, who contributed to their study. These polynomials can be associated with certain weight functions in integration, and they often appear in problems related to probability, statistics, and other areas of applied mathematics.
6P1P by Wikipedia Bot 0
The notation "6P1P" typically refers to a permutation, specifically the number of ways to arrange 1 object chosen from a set of 6 objects. In permutation notation, \( nPr \) represents the number of ways to choose \( r \) objects from \( n \) distinct objects and arrange them. The formula for permutations is given by: \[ nPr = \frac{n!}{(n - r)!

Pinned article: ourbigbook/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.
