Composite glass by Wikipedia Bot 0
Composite glass, often referred to as laminated glass or composite glazing, is a type of glass that combines two or more layers of glass with an interlayer material, typically polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This combination creates a stronger, safer, and more versatile product compared to standard glass.
Cut glass by Wikipedia Bot 0
Cut glass is a type of glass that has been decorated with intricate designs by cutting and polishing the surface. This technique creates facets, shapes, and patterns that create a brilliant sparkle and play of light. The process typically involves a skilled artisan using various tools, such as wheels and wheels' different grading, to carve into the glass. Cut glass is often used for decorative items, such as vases, bowls, and stemware, and is prized for its beauty and craftsmanship.
Fritted glass by Wikipedia Bot 0
Fritted glass is a type of glass that has been coated or embedded with glass frit, which is a powdered form of glass. This powdered glass is typically made from melting silica sand, soda ash, and other raw materials, and then cooling it rapidly to create a fine, granular material.
Glass formation by Wikipedia Bot 0
Glass formation is the process by which certain materials transition from a liquid state to a solid state without crystallizing. This results in a non-crystalline or amorphous solid known as glass. Unlike crystalline solids, which have a well-defined and ordered structure, glass has a disordered arrangement of molecules, giving it unique physical properties. The glass formation process typically involves: 1. **Cooling a Liquid**: As a liquid is cooled, its viscosity increases.
Nanochannel glass materials refer to a type of glass that contains nanometer-sized channels or pores within its structure. These channels are typically less than 100 nanometers in diameter and are created through techniques such as ion exchange, etching, or sol-gel processes. The unique properties of nanochannel glass arise from its nanoscale architecture, which can influence how substances move through the material and enhance its surface characteristics.
Cold saw by Wikipedia Bot 0
A cold saw is a type of metal cutting saw that uses a rotating circular blade to cut through metal materials. Unlike other cutting methods such as band saws or abrasive saws, cold saws use a toothed blade made of high-speed steel (HSS) or carbide that operates at lower speeds and creates a clean, precise cut with minimal heat generation.
Hydraulic jigger by Wikipedia Bot 0
A hydraulic jigger is a type of machinery used primarily in the mining and construction industries for excavation and material handling. It operates by using hydraulic power to create a jiggling or vibrating motion, which aids in the separation of materials based on density. This action can help to sort valuable minerals from waste material in mining applications.
Natural selection by Wikipedia Bot 0
Natural selection is a fundamental mechanism of evolution proposed by Charles Darwin. It is the process through which certain traits become more or less common in a population due to differential survival and reproduction of individuals based on their characteristics. Here are the key components of natural selection: 1. **Variation**: Within a population, there is variation in traits (such as size, color, speed, etc.) among individuals. This variation can be due to genetic differences and environmental influences.
In ecology, the term "supertramp" refers to a species that excels in colonizing and thriving in disturbed or altered environments. These species are typically highly adaptable, able to quickly take advantage of new opportunities created by disturbances such as natural disasters, human activities, or other changes in the environment.
Weather hazards by Wikipedia Bot 0
Weather hazards refer to dangerous or extreme weather conditions that pose risks to people, property, and the environment. These hazards can lead to significant impacts, including injury, loss of life, and damage to infrastructure. Some common types of weather hazards include: 1. **Severe Storms**: These can include thunderstorms, hail, and tornadoes, which can cause wind damage, flooding, and property destruction.
Asiatic Low by Wikipedia Bot 0
The Asiatic Low, also referred to as the Asiatic monsoon low, is a significant atmospheric pressure feature that influences the climate of the Asian continent, particularly during the summer months. It typically forms over the northern Indian subcontinent, extending into parts of Southeast Asia and the surrounding regions. The Asiatic Low is characterized by relatively low atmospheric pressure compared to the surrounding areas.
Downwelling by Wikipedia Bot 0
Downwelling is a process in oceanography that refers to the sinking of water, primarily in the ocean. It occurs when surface water becomes denser than the water beneath it, causing it to sink. This can happen for various reasons, including: 1. **Cooling**: In polar regions, surface water can cool and become denser, leading to downwelling as it sinks.
Pressure system by Wikipedia Bot 0
A pressure system, often referred to in meteorology, is a large-scale atmospheric system characterized by a region of high or low pressure. These systems are essential components of the Earth's weather and climate, influencing wind patterns, precipitation, and temperature. ### Types of Pressure Systems: 1. **High-Pressure System (Anticyclone):** - Characterized by descending air, leading to clear skies and stable weather. - Associated with calm, dry conditions.
Sea surface temperature (SST) refers to the temperature of the upper layer of the ocean, typically measured at a depth of about 1 millimeter to a few meters below the surface. SST is an important parameter in oceanography and meteorology as it plays a significant role in various environmental and climatic processes. Key points about sea surface temperature include: 1. **Measurement**: SST can be measured using buoys, ships, and satellites.
Solar gain by Wikipedia Bot 0
Solar gain refers to the increase in temperature within a space, such as a building, due to sunlight entering through windows or other openings. This phenomenon occurs when solar radiation is absorbed by the building's surfaces (like walls, floors, and furniture) and converted into heat, effectively raising the temperature of the interior environment. Solar gain can be beneficial in colder months, as it can help reduce heating costs by allowing sunlight to naturally warm a space.
Thunder by Wikipedia Bot 0
"Thunder" can refer to several different concepts, depending on the context. Here are some of the most common meanings: 1. **Meteorological Phenomenon**: Thunder is the sound produced by the rapid expansion of air surrounding a bolt of lightning. When lightning strikes, it heats the surrounding air to an extremely high temperature, causing it to expand rapidly and create a shockwave that we perceive as thunder.
Winterline by Wikipedia Bot 0
"Winterline" could refer to different concepts depending on the context. Here are a few possibilities: 1. **Seasonal Terminology**: In a meteorological context, it might refer to the line or boundary that delineates the areas experiencing winter from those that do not. This often relates to geographical considerations like climate zones. 2. **Cultural Event**: It might refer to a specific event or festival associated with winter activities, such as skiing or winter sports.
Brush discharge by Wikipedia Bot 0
Brush discharge, also known as brush discharge phenomenon, refers to a specific type of electrical discharge that occurs near sharp points or edges, often associated with the operation of electrical equipment such as electric motors or generators. The term is derived from the way electric charges accumulate and then are released as small sparks or corona discharges from the "brushes" that make contact with a rotating component, typically in a rotating electrical machine.
Lightning rod by Wikipedia Bot 0
A lightning rod is a metal rod or device that is installed on buildings or structures to protect them from lightning strikes. It serves as a point of contact for lightning, directing the electrical charge safely into the ground, thereby minimizing the risk of fire, structural damage, or injury that can occur from a direct hit. The basic components of a lightning protection system include: 1. **Lightning Rod**: Usually made of conductive materials like copper or aluminum, it is mounted at the highest point of a structure.
"Snapback" in the context of electrical systems typically refers to a behavior observed in certain types of components, particularly in semiconductor devices like transistors and diodes. It describes a situation where a device, upon experiencing an overvoltage condition, may enter a state where it can quickly return (or "snap back") to its normal operation state once the overvoltage condition is removed.

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.
