A wave motor, often referred to in a broader context as a wave energy converter (WEC), is a device designed to capture and convert the energy generated by ocean waves into usable energy, typically electricity. These systems harness the kinetic and potential energy of waves as they move up and down and back and forth on the surface of the ocean.
Gilding is a decorative technique that involves applying a thin layer of gold or a gold-like substance to a surface to create a luxurious finish. This process can be applied to various materials, including wood, metal, paper, and ceramics. There are several methods of gilding, including: 1. **Gold Leaf Gilding**: Involves applying extremely thin sheets of gold leaf to a surface, often using an adhesive or glue.
Witold Nowacki is not widely known in mainstream contexts, and there may be multiple individuals with that name.
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.
BLOSUM, short for "Blocks Substitution Matrix," refers to a series of substitution matrices used for sequence alignment, primarily in the field of bioinformatics. These matrices are designed to score alignments between protein sequences based on observed substitutions in blocks of homologous sequences. The BLOSUM matrices are indexed by a number (BLOSUM62, BLOSUM80, etc.), where the number indicates the minimum level of sequence identity among the sequences used to create the matrix.
64 is a natural number that follows 63 and precedes 65. It is an important number in various contexts: 1. **Mathematics**: - It can be expressed as \(8^2\) (8 squared) or \(2^6\) (2 raised to the power of 6). - It is a perfect square as well as a perfect sixth power.
The IBM PS/2 (Personal System/2) was a line of personal computers introduced by IBM in April 1987. It was designed to succeed the IBM PC and PC/AT lines, offering advancements in hardware and software compatibility. The PS/2 line was significant for several reasons: 1. **Microchannel Architecture (MCA)**: PS/2 introduced the Microchannel Architecture, a new bus standard that replaced the older ISA (Industry Standard Architecture) used in previous IBM PCs.
A water balloon is a small, elastic balloon that is specifically designed to be filled with water. Typically made from a thin, flexible rubber or latex material, water balloons are commonly used for recreational purposes, such as in water balloon fights, games, and parties. To use a water balloon, it is typically stretched over a faucet or filled using a hose, allowing water to fill the balloon until it reaches the desired size.
The Padé table is a mathematical tool used in the context of Padé approximants, which are a type of rational function approximation of functions. The Padé approximant of a function is typically better than a Taylor series in terms of capturing the function's behavior, especially near points of singularity or in cases where the series may not converge. The Padé table organizes the coefficients of the Padé approximants in a structured way.
The notation \(0.999...\) represents a repeating decimal, which means that the digit 9 continues indefinitely. In mathematics, it is established that \(0.999...\) is equal to \(1\). Here's a simple way to understand why: 1. Let \(x = 0.999...\). 2. If we multiply both sides of the equation by \(10\), we get: \[ 10x = 9.999... \] 3.
Ulam numbers are a sequence of integers that start with the numbers 1 and 2. Subsequent Ulam numbers are generated using a specific rule: each Ulam number is the smallest positive integer that can be expressed as the sum of two distinct earlier Ulam numbers in exactly one way. The sequence begins as follows: 1. The first two Ulam numbers are 1 and 2.
A Baire set is a concept from descriptive set theory, a branch of mathematical logic dealing with different levels of complexity in sets of real numbers or points in topological spaces. In the context of a Polish space, which is a separable completely metrizable topological space, Baire sets can be defined in relation to the constructible hierarchy of sets.
"Cardo" can refer to different things depending on the context: 1. **Geographical Term**: In ancient Roman towns, the "Cardo" was one of the principal streets, typically running north-south. It was an essential component of the Roman grid layout for urban planning.
In the context of lasers, "gain" refers to the amplification of light that occurs within the laser medium. More specifically, it represents the increase in the intensity of light as it travels through the gain medium, which is the material that provides the necessary optical gain for lasing to occur.
The Journal of Nanoscience and Nanotechnology is a peer-reviewed scientific journal that focuses on research in the field of nanoscience and nanotechnology. It publishes articles covering a wide range of topics related to the manipulation and application of materials at the nanoscale, typically at dimensions of 1 to 100 nanometers.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
