Compressed fluid refers to a fluid (liquid or gas) that is subjected to pressure higher than its atmospheric pressure, reducing its volume and increasing its density. When a fluid is compressed, its molecules are forced closer together, altering its physical properties. This concept is commonly applied in various fields, including engineering, thermodynamics, and fluid mechanics.
"The Invisible Maniac" is a 1990 low-budget horror-comedy film directed by Adam Rifkin. The movie revolves around a brilliant but disturbed scientist who develops a formula that makes him invisible.

IBM Informix C-ISAM (C Indexed Sequential Access Method) is a technology used for managing indexed sequential access to data in databases. It is part of the IBM Informix database management system, which is designed to handle various types of data storage and retrieval efficiently. C-ISAM provides a set of API functions that enable developers to perform operations on data files, such as creating, reading, writing, and deleting records.
The aerodynamic center (AC) of an airfoil or aircraft is a crucial concept in aerodynamics. It is defined as the point along the chord line of an airfoil at which the aerodynamic forces (specifically lift and drag) are considered to act. At this point, the moment due to aerodynamic forces remains constant with changes in the angle of attack.
The Küssner effect refers to a phenomenon observed in the context of auditory perception and the function of the cochlea, specifically related to frequency selectivity and temporal coding of sound. It describes how certain auditory stimuli can lead to a shift in the frequency response of the cochlea, affecting how sounds are perceived at different frequencies. In more technical terms, the Küssner effect highlights the interaction between different frequency components within a sound wave and how these interactions may influence the overall perception of that sound.
Bloom's Taxonomy is a framework used in education to classify learning objectives and outcomes into different levels of complexity and specificity. It was created by a group of educational psychologists, led by Benjamin Bloom, in the 1950s. The original taxonomy included six levels, which are often represented hierarchically. The levels are: 1. **Knowledge**: Recall of facts and basic concepts (e.g., memorizing definitions).
The Capillary number (Ca) is a dimensionless number that describes the relative effect of viscous forces to surface tension forces in a fluid. It is a critical parameter in fields such as fluid mechanics, petroleum engineering, and the study of multiphase flows.
The term "Darwin drift" is not widely recognized in scientific literature or biology, and it may not have a specific or established definition. However, it might refer to concepts related to evolutionary biology or genetic drift as they pertain to Charles Darwin's theories on evolution.
The De Brouckere mean diameter is a concept used in the field of sedimentology and particle size analysis. It is defined as the average diameter of particles in a sediment sample, calculated in such a way that it accounts for the surface area of the particles rather than just their linear dimensions. The De Brouckere mean diameter is often used when studying granular materials or sediments to provide a more accurate depiction of the particle size distribution.
The discharge coefficient (often denoted as \( C_d \)) is a dimensionless number used in fluid dynamics to characterize the flow through an orifice, nozzle, or other flow constrictions. It represents the efficiency of the flow as it passes through a restriction relative to the theoretical flow predicted by Bernoulli's equation.

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.
