t. e. In mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry . Analytic geometry is used in physics and engineering, and also in aviation, rocketry, space science, and spaceflight. It is the foundation of most modern ...
Continuum mechanics. Archimedes' principle (also spelled Archimedes's principle) states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. [1] Archimedes' principle is a law of physics fundamental to fluid mechanics.
Descartes on Polyhedra: A Study of the "De solidorum elementis" is a book in the history of mathematics, concerning the work of René Descartes on polyhedra.Central to the book is the disputed priority for Euler's polyhedral formula between Leonhard Euler, who published an explicit version of the formula, and Descartes, whose De solidorum elementis includes a result from which the formula is ...
Critical race theory. Critical race theory ( CRT) is an interdisciplinary academic field focused on the relationships between social conceptions of race and ethnicity, social and political laws, and media. CRT also considers racism to be systemic in various laws and rules, and not only based on individuals' prejudices.
The conspiracy is believed to have broad goals, usually conceived as securing control of a country, a region, or even the entire world. The goals are sweeping, whilst the conspiratorial machinery is generally simple: a single, evil organization implements a plan to infiltrate and subvert existing institutions.
The " ghost in the machine " is a term originally used to describe and critique the concept of the mind existing alongside and separate from the body. In more recent times, the term has several uses, including the concept that the intellectual part of the human mind is influenced by emotions; and within fiction, for an emergent consciousness ...
Andreas Cellarius 's illustration of the Copernican system, from the Harmonia Macrocosmica. Heliocentrism [a] (also known as the heliocentric model) is a superseded astronomical model in which the Earth and planets revolve around the Sun at the center of the universe. Historically, heliocentrism was opposed to geocentrism, which placed the ...
Corpuscular theory of light. In optics, the corpuscular theory of light states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess impetus. This was based on an alternate description of atomism of the time period.
