Nicomedes was an ancient Greek mathematician who lived during the Hellenistic period, around the 2nd century BCE. He is best known for his contributions to geometry, particularly in relation to the concepts of conic sections and the construction of geometrical figures. One of his notable achievements is the invention of the "Nicomedean spiral," which is a type of spiral that can be used to solve problems related to the squaring of the circle.
Nicoteles of Cyrene was an ancient Greek philosopher and mathematician known primarily for his work in the area of mathematics. He is often associated with the development of geometry and numerical concepts in classical antiquity. However, detailed information about him is relatively sparse compared to more prominent philosophers of the time, such as Plato or Aristotle. Much of what is known about Nicoteles comes from later references and interpretations rather than extensive primary texts.
Philolaus was a Greek philosopher from the Pythagorean school, active around the 5th century BCE. He is best known for his work on cosmology and philosophy, particularly in relation to mathematics and music. Philolaus is notable for his belief that the Earth is not the center of the universe, an idea that predates and anticipates later heliocentric models.
Gumblar is a type of web-based malware that primarily targets websites running on content management systems (CMS) like WordPress, Joomla, and others. It is named after the Gumblar.com domain, which was used by attackers to distribute the malware. The malware typically spreads through compromised websites, often by exploiting security vulnerabilities, and it can inject malicious scripts into the pages of infected sites.
The term "Philon" could refer to several different things depending on the context. Here are a few possibilities: 1. **Philo of Alexandria**: A Hellenistic Jewish philosopher who lived in Alexandria in the first century CE. He is known for blending Greek philosophy, particularly Stoicism and Platonism, with Jewish religious thought. 2. **Philon (spelling variation)**: This could refer to a name or a specific brand, product, or organization.
Proclus, also known as Proclus Diadochus, was a prominent Greek philosopher who lived from approximately 412 to 485 AD. He is best known as a major figure of Neoplatonism, a philosophical system that builds upon the ideas of Plato and integrates various aspects of earlier philosophical traditions.
Serenus of Antinoöpolis was a notable figure in ancient Roman Egypt, likely known for his contributions to philosophy, medicine, or early Christian thought, although specific details about his life and work are scarce. He is often mentioned in the context of ancient writings or inscriptions, but much of the historical context surrounding him remains limited. His name appears in some scholarly resources related to early Christian texts or Greek philosophy.
Antiphon of Athens (c. 480 – c. 411 BC) was a pre-Socratic philosopher and a Sophist, known for his contributions to philosophy and rhetoric, especially in the realm of social and political thought. He is often considered one of the early figures in the development of political theory and moral philosophy.
The term "Theudius" does not appear to refer to any well-known concept, historical figure, or entity in widely recognized literature or online resources as of my last update in October 2023. It might be a misspelling, a lesser-known term, or something specific to a niche context such as a video game, book, or fictional universe.
Xenocrates (c. 396–314 BCE) was a prominent ancient Greek philosopher and a student of Plato. He succeeded Plato as the head of the Academy in Athens and is known for his contributions to philosophy, particularly in the fields of metaphysics, ethics, and mathematics. Xenocrates is also credited with developing ideas related to the nature of the soul and the concept of transmigration.
In aerodynamics, the angle of incidence refers to the angle between the chord line of an airfoil (such as a wing) and the relative wind or the airflow that is approaching it. It is a critical parameter in determining how an airfoil generates lift. The chord line is an imaginary straight line that connects the leading edge (front) of the airfoil to the trailing edge (back).
A **conformal map** is a function between two shapes or spaces that preserves angles locally but may change sizes. In more technical terms, a conformal mapping is a function \( f \) that is holomorphic (complex differentiable) and has a non-zero derivative in a domain of the complex plane. ### Key Properties of Conformal Maps: 1. **Angle Preservation**: Conformal maps preserve the angle between curves at their intersections, which means the local geometric structure is maintained.
The Seikilos Epitaph is an ancient Greek inscription that is considered one of the oldest known complete musical compositions. It dates back to around the 1st century CE and was discovered on a tombstone in modern-day Turkey. The epitaph is notable for its combination of a poetic text and musical notation, which serves as both a memorial and a reflection on the transient nature of life. The inscription includes lyrics that express themes of love, life, and the inevitability of death.
Cratylism is a philosophical and linguistic theory attributed to the ancient Greek philosopher Cratylus, a character in Plato's dialogues. Cratylus believed in a sacred connection between words and their meanings, suggesting that names have an intrinsic link to the objects they refer to. This idea contrasts with the conventionalist view, which holds that the relationship between words and their meanings is arbitrary and established by social convention.
Plato's theory of the soul is a central aspect of his philosophical thought, particularly in his dialogues such as "Phaedrus," "Phaedo," and "Republic." Here are the key components of his theory: 1. **Tripartite Soul**: Plato divides the soul into three distinct parts: - **Rational (Logos)**: This part of the soul seeks truth and is responsible for reasoning and philosophical thought.
Angular distance is a measure of the angle between two points or directions, typically on a sphere or a circle. It is expressed in degrees or radians and represents the shortest angle through which one must rotate to align one point or direction with another. In a spherical context, angular distance can be calculated using various formulas depending on the coordinates of the points involved.
Hyginus Gromaticus was a Roman writer and geographer who is primarily known for his work on surveying and land measurement in ancient Rome. His most notable work is entitled "De limitations rusticorum" (On the Boundaries of Land), which serves as a manual for land surveying, outlining techniques and principles used in agronomy during the Roman era.
The 2020 German Presidency of the Council of the European Union refers to Germany's six-month leadership role in the Council of the EU, which took place from July 1 to December 31, 2020. During this period, Germany, as the rotating president, played a crucial role in steering the agenda of the Council, which represents the member states of the EU.
The Aachen Treaty, formally known as the Treaty of Aachen, is a bilateral agreement between France and Germany that was signed on January 22, 2019. The treaty aims to deepen cooperation between the two countries in various fields, including defense, security, diplomacy, and culture, as well as to strengthen European integration.
Axis-angle representation is a way to describe rotations in three-dimensional space using a combination of a rotation axis and an angle of rotation about that axis. This representation is particularly useful in computer graphics, robotics, and aerospace for representing orientations and rotations. ### Components of Axis-Angle Representation: 1. **Axis**: This is a unit vector that defines the direction of the axis around which the rotation occurs.

. 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.
