Infragravity wave by Wikipedia Bot 0
Infragravity waves are a type of low-frequency wave typically found in ocean environments. They have periods that range from approximately 30 seconds to several minutes, which makes them significantly longer than regular wind-driven surface waves, which often have periods of a few seconds to around 10 seconds. Infragravity waves are generated by the interaction of regular ocean waves with the shoreline and the seafloor. When wind-generated waves break, they can create these longer-period waves through non-linear interactions.
Infrasound by Wikipedia Bot 0
Infrasound refers to sound waves that have frequencies below the lower limit of human hearing, typically defined as below 20 hertz (Hz). These low-frequency sounds can be generated by a variety of natural and man-made sources, including earthquakes, volcanic eruptions, ocean waves, heavy machinery, and even certain types of music. Infrasound can travel long distances and penetrate various materials more effectively than higher-frequency sounds.
Initialization in programming refers to the process of assigning an initial value to a variable or object at the point when it is created. It is a critical step in programming, as it ensures that the variable has a defined state before it is used in computations or operations. Here's a breakdown of initialization: 1. **Purpose**: Initialization is important because uninitialized variables often contain garbage values (random data left in memory), which can lead to unpredictable behavior or errors in a program.
Innovations in Theoretical Computer Science (TCS) encompass a range of advancements that push the boundaries of our understanding of computation, algorithms, complexity theory, and related fields.

The De Sitter double star experiment is a thought experiment proposed by the Dutch astronomer Willem de Sitter in the early 20th century. It is intended to illustrate aspects of general relativity, particularly the effects of gravity on light and the concept of gravitational wave propagation. In this experiment, assume there are two massive bodies (the "double stars") orbiting around each other. According to general relativity, massive objects curve spacetime, affecting the paths of nearby light rays.
The Descriptive Color Names Dictionary is a resource that provides names for colors based on descriptive terms rather than standard color codes or technical specifications. These names are often more relatable and memorable, making them useful for a variety of applications such as art, design, fashion, and marketing. In such a dictionary, colors may be described using a combination of familiar terms that relate to nature, emotions, or objects (e.g., "sky blue," "rose red," "forest green").

In chemistry, deposition refers to the process by which a substance transitions from a gas directly to a solid, bypassing the liquid state. This phase transition is the reverse of sublimation, where a solid becomes a gas without passing through the liquid phase. Deposition typically occurs under specific conditions of temperature and pressure, usually at low temperatures and high pressures. It is an important process in various natural phenomena and industrial applications.
The Quine–McCluskey algorithm is a method used for minimizing Boolean functions, which is particularly valuable in digital logic design and circuit simplification. It is an algorithmic approach that serves as a systematic way to find the minimal expression of a Boolean function represented in terms of its truth table or its minterms.

Demulsifier by Wikipedia Bot 0
A demulsifier is a chemical agent used to separate emulsions, which are mixtures of two or more immiscible liquids, typically oil and water. In many industrial processes, these emulsions can form during activities such as oil extraction, refining, or wastewater treatment. Demulsifiers work by destabilizing the emulsion, allowing the individual components to separate more easily.
Denaturation of fissile materials refers to the process of altering the composition or structure of nuclear materials (like uranium or plutonium) to reduce their effectiveness or usefulness for nuclear fission reactions. This is typically done to ensure that the material cannot be used for nuclear weapons proliferation.

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.
