The chromatic hexachord is a musical concept that originated in the Renaissance period, particularly within the context of music theory. It refers to a specific collection of six pitches, or notes, spanning a perfect fourth in the chromatic scale. The chromatic hexachord can be understood as a set of notes that includes all the half steps (semitones) within a certain range, typically from a root note to a note a perfect fourth above it.

A community-controlled game is a type of video game that emphasizes player involvement in its development, management, or ongoing content. In these games, the community of players has a significant say in various aspects of the game, including design choices, updates, and sometimes even governance. This can manifest in several ways: 1. **Crowdsourced Development**: Developers may solicit feedback, ideas, or even content directly from the community during the development process.

He is particularly recognized for his work on fish biology and contributed to the understanding of marine ecosystems. Additionally, "E. S. Russell" might also refer to various other entities that include similar initials or names, but without more context, it’s challenging to provide a precise answer.
Étale topos by Wikipedia Bot 0
The concept of an étale topos arises from algebraic geometry and the study of schemes, particularly in the context of Grothendieck's pursuit of a more geometric point of view on algebraic structures. In basic terms, a topos is a category that behaves similarly to the category of sets, but with additional structure that allows for the handling of sheaves, logic, and categorical properties.
Ethel Bellamy by Wikipedia Bot 0
Ethel Bellamy does not appear to be a widely recognized term, person, or concept in publicly available knowledge as of my last update in October 2023. It could potentially refer to a lesser-known individual, a fictional character, or something specific to a certain context.
The ethics of quantification refers to the moral implications and considerations surrounding the use of quantitative data, metrics, and measurements in various fields such as social sciences, health care, economics, and policy-making. It explores how numerical data can influence decision-making, public perceptions, and social practices while raising questions about fairness, accountability, and the potential consequences of over-relying on quantitative measures.
Capacitor by Ciro Santilli 37 Updated +Created
The fundamental intuition about capacitors is that they never let electrons through.
They can only absorb electrons up to a certain point, but then the pushback becomes too strong, and current stops.
Therefore, they cannot conduct direct current long term.
For alternating current however, things are different, because in alternating current, electrons are just jiggling back and forward a little bit around a center point. So you can send alternating current power across a capacitor.
The key equation that relates Voltage to electric current in the capacitor is:
So if a voltage Heavyside step function is applied what happens is:
  • the capacitor fills up instantly with an infinite current
  • the current then stops instantly
More realistically, one may consider the behavior or the series RC circuit to see what happens without infinities when a capacitor is involved as in the step response of the series RC circuit.

The main ethnic groups in Vojvodina include: 1. **Serbs** - The largest ethnic group in Vojvodina. 2. **Hungarians** - A significant minority, especially in northern areas. 3. **Slovaks** - A well-established ethnic community with a presence in various towns.
Edgar Zilsel by Wikipedia Bot 0
Edgar Zilsel (1885-1944) was an Austrian philosopher of science and a prominent figure in the history and philosophy of science. He is best known for his work on the relationship between science, technology, and society, and for his contributions to the understanding of the social aspects of scientific knowledge.
An ethnolinguistic group is a category of people who share both a common ethnic background and a common language. This concept combines aspects of ethnicity, which refers to shared cultural, historical, and sometimes biological traits, with linguistics, the study of language. Ethnolinguistic groups often have distinct cultural practices, traditions, and social norms that are associated with their language and ethnic identity.

Eun Jung Kim is a researcher known for her contributions to the field of parameterized complexity, which is a branch of computational complexity theory. Parameterized complexity focuses on classifying problems based on their inherent difficulty with respect to certain parameters, allowing for more nuanced analyses of algorithms that might be computationally hard in general but easier when certain aspects of the input (the parameters) are fixed or small.

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.
