Avogadro's law by Wikipedia Bot 0
Avogadro's law states that, at constant temperature and pressure, equal volumes of gases contain an equal number of molecules, regardless of the type of gas. This means that the volume of a gas is directly proportional to the number of moles (or molecules) of the gas when temperature and pressure are kept constant.
Osmometer by Wikipedia Bot 0
An osmometer is a scientific instrument used to measure the osmotic pressure or osmotic concentration of a solution. Osmotic pressure is the pressure required to prevent the flow of a solvent across a semipermeable membrane, which is a fundamental concept in physical chemistry and biology. There are several types of osmometers, including: 1. **Freezing Point Depression Osmometers**: These measure the freezing point of a solution.
Air time (rides) by Wikipedia Bot 0
"Air time" in the context of rides, particularly roller coasters, refers to the sensation of weightlessness or the feeling of being lifted out of one's seat during certain parts of a ride. This phenomenon occurs when the ride experiences negative G-forces, typically during steep drops, sudden hills, or inversions.
Sudden unintended acceleration (SUA) refers to a phenomenon in which a vehicle unexpectedly and uncontrollably increases speed without the driver pressing the accelerator pedal. This can lead to dangerous situations, including accidents and injuries. SUA can be caused by a variety of factors, including: 1. **Electronic Malfunctions**: Issues with the vehicle's electronic systems, such as throttle control, could potentially cause unintended acceleration.
High-g training by Wikipedia Bot 0
High-g training refers to a type of physical conditioning aimed at preparing individuals, particularly pilots and astronauts, for environments where they experience high gravitational forces (g-forces). In these situations, the body experiences a significant increase in weight, which can lead to challenges such as loss of consciousness (GLOC), impaired vision, and other physiological effects.
Shock (mechanics) by Wikipedia Bot 0
In mechanics, "shock" typically refers to a sudden and drastic change in load or condition that leads to the rapid application of force or energy. This term is often used in the context of impact mechanics, where a body experiences a sudden force due to collision, strike, or other abrupt interactions.
Spatial acceleration generally refers to the rate of change of velocity of an object in motion, taking into account its position in three-dimensional space. It is a vector quantity, which means it has both a magnitude and a direction. In physics and engineering, especially in mechanics, spatial acceleration can be understood in the context of motion dynamics of objects.
Tensors are mathematical objects that generalize scalars and vectors to higher dimensions and are used to describe various physical quantities in science and engineering. They can be thought of as multi-dimensional arrays that transform according to specific rules under change of coordinates. Here are some key points about tensors as physical quantities: 1. **Definition**: A tensor is a mathematical entity that can be represented as a multi-dimensional array of numbers.
Visibility by Wikipedia Bot 0
Visibility generally refers to the degree to which something can be seen or perceived. The term can have different meanings depending on the context: 1. **Weather**: In meteorology, visibility refers to the distance one can clearly see. Poor visibility can result from fog, rain, snow, or dust, affecting driving and outdoor activities. 2. **Business/Marketing**: In a business context, visibility often refers to how easily a brand, product, or service can be noticed by potential customers.

Aggregate modulus by Wikipedia Bot 0
Aggregate modulus is a term used in civil engineering, particularly in the context of concrete and asphalt mixtures. It refers to the overall modulus of elasticity of the aggregate component within these materials. The modulus of elasticity is a measure of a material's stiffness and its ability to deform elastically (i.e., non-permanently) when subjected to stress. In concrete, the aggregate modulus can influence the strength, durability, and overall performance of the finished concrete product.
Kainosymmetry by Wikipedia Bot 0
Kainosymmetry is not a widely recognized term in mainstream academic or scientific literature. However, breaking down the word can give some insight into its possible meanings. The prefix "kaino-" is derived from the Greek word "kainos," which means "new" or "recent." The suffix "symmetry" typically pertains to balance or proportion in various contexts, such as in mathematics, physics, or art.
Square by Wikipedia Bot 0
Square, now known as Block, Inc., is a financial services and mobile payment company co-founded by Jack Dorsey and Jim McKelvey in 2009. Originally, Square was best known for its point-of-sale (POS) systems and mobile payment solutions that allowed small businesses to accept card payments using a smartphone or tablet equipped with a card reader.
Orbital angular momentum is a concept from quantum mechanics that describes the angular momentum of particles due to their motion around a central point. For free electrons, which are not bound to atoms, the orbital angular momentum is quantified using the quantum mechanical principles of angular momentum.
"Orders of magnitude" generally refers to the scale or size of a quantity relative to a base unit, often expressed as a power of ten. In the context of angular momentum, it refers to the comparison of the angular momentum of different systems or objects based on their mathematical formulations, which typically involve mass, distance, and velocity.
Cubic foot by Wikipedia Bot 0
A cubic foot is a unit of volume that is equal to the volume of a cube with edges that are one foot long. In other words, it measures how much space an object occupies in three dimensions, specifically for volume measurement in the imperial system commonly used in the United States.
Distance measure by Wikipedia Bot 0
A distance measure, often referred to as a distance metric or dissimilarity measure, is a quantitative way of determining the distance or similarity between two points in a given space. These measures are used in various fields such as mathematics, computer science, statistics, and machine learning. Here are some common distance measures: 1. **Euclidean Distance**: - The straight-line distance between two points in Euclidean space.
Electric field by Wikipedia Bot 0
An electric field is a region around a charged particle or object within which other charged particles experience a force. It is a vector field that represents the force per unit charge that a positive test charge would experience at any point in space.
Decagon by Wikipedia Bot 0
A decagon is a polygon with ten sides and ten angles. In a regular decagon, all sides are equal in length and all angles are equal in measure, with each internal angle measuring 144 degrees. The sum of all internal angles in a decagon is 1,440 degrees. Decagons can be found in various fields, including architecture, design, and mathematics.
Heptagon by Wikipedia Bot 0
A heptagon is a polygon that has seven sides and seven angles. The term "heptagon" comes from the Greek word "hepta," meaning seven. In a heptagon, the sum of the interior angles is 900 degrees, which can be calculated using the formula \((n - 2) \times 180\), where \(n\) is the number of sides. Heptagons can be regular or irregular.

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.
