Physics is the natural science that studies matter, energy, and the fundamental forces of nature. It seeks to understand how the universe behaves, by examining the interactions between different physical systems and the laws that govern these interactions. Physics can be divided into several branches, including: 1. **Classical Mechanics**: The study of the motion of objects and the forces acting on them. This includes concepts such as gravity, mass, and acceleration.
Fields of mathematics refer to the various specialized areas or branches within the discipline of mathematics. Each field encompasses specific concepts, theories, methods, and applications. Here are some of the main fields of mathematics: 1. **Algebra**: The study of mathematical symbols and the rules for manipulating these symbols. It includes various subfields such as linear algebra, abstract algebra, and algebraic geometry. 2. **Geometry**: The study of shapes, sizes, and properties of space.
KCNS3, or "Potassium Voltage-Gated Channel Subfamily S Member 3," is a gene that encodes a protein belonging to the family of voltage-gated potassium channels. These channels are integral membrane proteins that play a crucial role in the electrical activity of neurons and muscle cells by allowing the flow of potassium ions across the cell membrane.
Bitty Baby is a line of dolls produced by American Girl, designed for younger children, typically ages 3 and up. These dolls are meant to be a first baby doll experience, encouraging imaginative play and nurturing skills. Bitty Baby dolls come in a variety of skin tones, hair colors, and styles, allowing children to choose dolls that they can relate to or enjoy.
A practical number is a positive integer \( n \) that can be represented as a sum of distinct positive integers not exceeding \( n \). In other words, for a number to be practical, any integer up to \( n \) can be expressed as a sum of distinct integers chosen from the set of positive integers less than or equal to \( n \).
Cav1.1 refers to a type of voltage-gated calcium channel that is primarily found in skeletal muscle cells. It is a crucial component in the excitation-contraction coupling process, which translates electrical signals from the nervous system into muscle contraction. Cav1.1 is a large protein, and its full name is "calcium channel, voltage-dependent, L type, alpha 1S subunit.
The term "Trace class" can refer to different concepts depending on the context, but it is commonly associated with the field of functional analysis in mathematics, particularly in the study of operators on Hilbert spaces. In this context, a **trace class** (or **trace-class operator**) refers to a specific type of compact operator that has a well-defined trace.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.
