The Citizen Cyberscience Centre (CSC) is an initiative that focuses on fostering public engagement in scientific research through the use of digital technologies and citizen participation. It serves as a platform that enables volunteers to contribute to scientific projects, often through activities like distributed computing, data analysis, or data collection. The CSC aims to harness the power of crowdsourcing and citizen science, allowing non-experts to contribute to research efforts, thereby advancing scientific knowledge while also educating and engaging the public.
Geotechnical engineering is a branch of civil engineering that focuses on the behavior of soil and rock materials and their interaction with structures. It involves the study of the physical and mechanical properties of earth materials to assess how they will perform under various conditions, particularly when subjected to loading from structures such as buildings, bridges, dams, and tunnels.
Coats of arms featuring sunrays often symbolize light, divinity, enlightenment, or glory. In heraldry, sunrays can appear in various forms, such as a sun with alternating rays or just rays emanating from a central point. The presence of sunrays in a coat of arms can denote a connection to a family, region, or institution that values attributes associated with the sun, like vitality and positivity.
Coleen T. Murphy is an American biologist known for her research in the fields of aging and neurobiology. She is a professor at Princeton University and has made significant contributions to understanding the molecular mechanisms of aging, particularly in the model organism Caenorhabditis elegans (C. elegans), a type of nematode. Her studies often focus on the genetic and environmental factors that influence lifespan and healthspan, the period of life spent in good health.
The Q-Gaussian distribution is a generalization of the standard Gaussian (normal) distribution that arises in the context of nonextensive statistical mechanics, which was developed by Constantino Tsallis. This distribution is particularly useful when dealing with systems that exhibit long-range interactions, memory effects, or are far from equilibrium.
The Compactron is a type of vacuum tube that was developed in the 1960s by the Electronics Division of the General Electric Company. It is notable for its compact design, which integrates multiple functions within a single envelope. The Compactron combines several different components in one tube, allowing for functions like amplification, rectification, and more, thereby saving space and potentially reducing the overall cost and complexity of electronic circuits.
The metre per second (symbol: m/s) is a derived unit of speed in the International System of Units (SI). It measures how many meters are traveled in one second. It is commonly used to express the speed of objects, such as vehicles or the speed of sound. For example: - A car traveling at a speed of 60 m/s is moving 60 meters every second.
A washout filter is a type of digital filter commonly used in video processing and image handling, particularly in the context of graphics and video games. Its primary function is to reduce or eliminate the influence of very high-frequency noise in a signal, resulting in a smoother output.
The composition of yards and perches involves understanding their definitions and how they relate to measurements in the imperial or customary system of units. 1. **Yard**: - A yard is a unit of measurement equal to 3 feet or 36 inches. It is used in various contexts, including measuring distance, fabric, and land.
A "wasted vote" refers to a vote that does not contribute to the overall outcome of an election. This typically occurs in several situations: 1. **Voting for a Losing Candidate**: If a voter supports a candidate who ultimately does not win the election, their vote is considered wasted because it does not help that candidate achieve victory.
A Constant Amplitude Zero Autocorrelation (CAZAC) waveform is a type of signal used primarily in communications and radar systems. These waveforms are characterized by having constant amplitude and an autocorrelation function that has zero values at all non-zero time shifts. Essentially, this means that the waveform is designed to avoid self-interference at different time delays, which is desirable in many applications such as spread spectrum communication.
Content validity refers to the extent to which a measurement instrument, such as a test or questionnaire, accurately represents the construct it is intended to measure. It assesses whether the items or questions included in the instrument adequately cover the relevant content domain and whether they reflect the underlying theoretical concept. To establish content validity, experts typically engage in a few key activities: 1. **Defining the Construct**: A clear definition of the construct being measured is critical.
Continental crust is a type of Earth's crust that makes up the continents and the shallow seabed around them. It is generally thicker, older, and less dense than oceanic crust, which makes up the ocean floors. Here are some key characteristics of continental crust: 1. **Composition**: Continental crust is primarily composed of granitic rocks, which are rich in silica and aluminum. This composition is contrasted with oceanic crust, which is primarily basaltic and richer in iron and magnesium.
A Control-Lyapunov Function (CLF) is a concept used in control theory to design feedback controllers that stabilize nonlinear systems. It generalizes the idea of a Lyapunov function, which is a scalar function used to ascertain the stability of dynamical systems.
Short-range order (SRO) refers to the arrangement of particles, atoms, or molecules in a material over a limited distance, usually within a few atomic or molecular radii. It is a concept frequently used in the fields of solid state physics, materials science, and chemistry. In materials with short-range order, local structures or clusters may show a specific arrangement, but this order does not extend over longer distances.

A coronal hole is a region on the sun's atmosphere (the corona) that has a lower density and temperature compared to the surrounding areas. These holes appear dark in images taken in ultraviolet (UV) and X-ray wavelengths. Coronal holes are associated with open magnetic field lines, allowing solar wind—streams of charged particles (mostly electrons and protons)—to escape into space at high speeds. Coronal holes can vary in size and can last for days to months.
Chemical potential is a fundamental concept in thermodynamics and physical chemistry that describes the change in free energy of a system when an additional amount of substance is introduced, under constant temperature and pressure. It is a measure of the potential energy per particle in a system and reflects how the concentration of a species influences its behavior in a mixture.
The term "shipping ton" is often used to refer to a unit of measurement related to shipping and freight. However, it is important to clarify that "ton" can refer to different types of tons, which include: 1. **Gross Ton**: A unit used to measure the overall internal volume of a ship, including all its spaces (cargo, engine, etc.). One gross ton is equal to 100 cubic feet (approximately 2.83 cubic meters).
The Cosmic Calendar is a conceptual representation that compresses the history of the universe into a single year, providing a visual and temporal framework for understanding the vast timescales of cosmic events. It was popularized by astronomer Carl Sagan in his book "Cosmos". In this model, the entire 13.8 billion-year history of the universe is scaled down to a single year, where: - The Big Bang occurs at midnight on January 1st.

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.
