"Cogito, ergo sum" is a Latin philosophical proposition by René Descartes, which translates to "I think, therefore I am." This statement is a fundamental element of Western philosophy and serves as a foundational element in Descartes' larger argument for the existence of the self as a thinking being. Descartes introduced this idea in his work "Meditations on First Philosophy," where he sought to establish a secure foundation for scientific knowledge.

"Britten's Purcell Realizations" refers to a collection of arrangements and realizations by the British composer Benjamin Britten of selected works by Henry Purcell, one of England's most significant composers from the late 17th century. Britten, a 20th-century composer, was deeply influenced by Purcell's music and sought to bring it to new audiences through his unique interpretations.
"Animat" can refer to different concepts depending on the context. Here are a few possibilities: 1. **Animat (General Definition)**: In a broad sense, the term "animat" can refer to any animated entity or creature that can exhibit some form of movement or behavior. This could be in the context of robotics, animation, or virtual environments where creatures are designed to mimic real-life movements and interactions.
An **Evolving Digital Ecological Network** typically refers to a dynamic system or framework that encompasses various interconnected digital entities such as data, platforms, applications, and users, functioning much like an ecosystem in nature. Here are some key features and concepts that can be associated with this term: 1. **Interconnectedness**: Just as in a natural ecosystem, where different species and organisms interact with each other, in a digital ecological network, different digital entities (e.g.
Asphaltenes are complex, high-molecular-weight organic compounds found in crude oil and tar sands. They are classified as the heaviest and least soluble fractions of crude oil, typically characterized by their large size, aromatic nature, and the presence of heteroatoms such as nitrogen, sulfur, and oxygen. Asphaltenes play a significant role in various hydrocarbon systems, affecting properties such as viscosity, stability, and the overall behavior of petroleum liquids.
The Delta-v budget is a critical concept in spacecraft mission planning and astrodynamics. Delta-v (Δv) represents the change in velocity that a spacecraft must achieve to perform various maneuvers during its mission. The Delta-v budget outlines the total amount of Δv available for each phase of the mission and allocates it to the necessary maneuvers to ensure mission success.
An infantry support gun is a type of artillery piece designed to provide indirect fire support to infantry units. These guns are often characterized by their relatively smaller caliber compared to standard field artillery and are typically towed or mounted on vehicles for mobility. Their primary purpose is to engage enemy positions and provide tactical support for ground troops, especially in close support roles during infantry assaults.
Apparent retrograde motion is an optical phenomenon observed in astronomy where a planet appears to move backward in its orbit, relative to the stars in the background, for a period of time. This effect is not due to any actual change in the direction of the planet's orbit but is instead caused by the relative positions and motions of the Earth and the other planet.
A distant retrograde orbit (DRO) refers to a specific type of orbital trajectory that involves an object, such as a satellite, orbiting a larger celestial body (like a planet or moon) in a retrograde direction at a considerable distance. In this context, "retrograde" means that the object orbits in the opposite direction to the rotation of the primary body or the direction most other satellites orbits around that body.
Indulin AA-86 is a type of aromatic amine-based curing agent or hardener commonly used in epoxy formulations. It is particularly known for enhancing the curing process of epoxy resins, which are widely used in coatings, adhesives, and composite applications. Indulin AA-86 allows for improved chemical resistance, impact strength, and thermal stability in the cured epoxy product.
Neutron-star oscillation refers to the phenomenon in which neutron stars, extremely dense remnants of massive stars that have undergone supernova explosions, exhibit oscillatory modes of vibration or oscillation. These oscillations can occur in various forms and have different physical origins, providing key insights into the properties of neutron stars and the states of matter under extreme conditions. ### Types of Oscillations 1. **Fundamental Oscillations**: These involve the star expanding and contracting as a whole.
The Transiting Exoplanet Survey Satellite (TESS) is a NASA mission designed to search for exoplanets, which are planets located outside our solar system. Launched on April 18, 2018, TESS aims to identify new exoplanets by monitoring the brightness of nearby stars for periodic dips in brightness, a method known as the transit method.
"Abd al-Wajid" can refer to a few different contexts, but it is most commonly recognized as a name of Arabic origin, meaning "servant of the Finder" or "the one who finds." It is sometimes used as a given name in Islamic cultures. In a broader context, the name might be associated with historical or contemporary figures, including scholars, leaders, or artists.
A "frozen orbit" refers to a specific orbital configuration that allows a satellite to maintain a consistent pattern relative to the Earth’s surface over time. In this type of orbit, the satellite's ground track (the path it traces on the Earth's surface) repeats at regular intervals, usually on a daily basis. This means that after a certain number of days, the satellite will pass over the same point on Earth at the same local solar time.
Low-energy transfer refers to processes or techniques in various fields that involve the movement or exchange of energy at a low energy scale. The context in which the term is used can vary, so here are a few interpretations: 1. **Physics**: In particle physics, low-energy transfer might refer to interactions between particles that occur at low energy levels, as opposed to high-energy collisions that can create new particles. These interactions are often studied to understand fundamental forces and the properties of matter.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
