Awareness activism
Awareness activism refers to efforts and initiatives aimed at raising public consciousness about specific social, political, environmental, or health issues. The primary goal of awareness activism is to inform and educate the general population about these issues, often with the intention of fostering understanding, empathy, and ultimately inspiring action or change.
AN 51
AN 51 typically refers to "Advisory Notice 51," which is often issued by regulatory agencies or organizations in various fields, including aviation, finance, and engineering. These notices provide guidance, best practices, or updates on safety and regulatory issues. In aviation, for example, AN 51 might relate to safety regulations or operational procedures. The specific content and implications of AN 51 would depend on the context in which it is issued.
Ana Flávia Nogueira
Ana Flávia Nogueira is not a widely recognized public figure or concept, so it's possible that she could refer to a private individual or someone who is not notably documented in mainstream sources.
Quantum mechanical potentials
Quantum mechanical potentials refer to the mathematical functions that describe the potential energy landscape in which quantum particles (such as electrons, protons, and other elementary particles) interact and move. In quantum mechanics, potential energy plays a crucial role in determining the behavior of quantum systems, particularly in how particles are confined, how they can interact with one another, and how they can transition between energy states.
Analytic geometry
Analytic geometry, also known as coordinate geometry, is a branch of mathematics that uses algebraic principles to solve geometric problems. It involves the use of a coordinate system to represent and analyze geometric shapes and figures mathematically. Key concepts in analytic geometry include: 1. **Coordinate Systems**: The most common system is the Cartesian coordinate system, where points are represented by ordered pairs (x, y) in two dimensions or triples (x, y, z) in three dimensions.
John A. Hartigan
John A. Hartigan is not a widely recognized figure in popular culture, academia, or other well-documented fields up to my knowledge cutoff in October 2023. It is possible that he could be a private individual, a professional in a specific field, or someone who became notable after that date. If you have a specific context or field in mind (like literature, politics, science, etc.
The International Meridian Conference was a meeting held in Washington, D.C., in 1884, which aimed to establish a standard for the Prime Meridian and coordinate global timekeeping. The conference was attended by representatives from 25 nations and resulted in the adoption of the Greenwich Meridian as the prime reference point for international timekeeping and geography.
Ancient Greek philosophy laid the groundwork for many fields, including the philosophy of mind. This branch of philosophy deals with questions about consciousness, perception, thought, and the nature of the soul. Here are some key figures and concepts in the philosophy of mind from ancient Greece: 1. **Plato (c. 427-347 BCE)**: - Plato’s view of the mind is closely tied to his theory of Forms or Ideas.
Lisbeth Gronlund
Lisbeth Gronlund is a notable figure in the field of science and technology, particularly known for her work related to arms control and non-proliferation. She has contributed to discussions and analyses of nuclear weapons policy, as well as the implications of emerging technologies on global security. Gronlund has been associated with institutions such as the Union of Concerned Scientists, where she has engaged in research and advocacy efforts aimed at promoting safe and secure uses of science and technology.
Anders Hald
Anders Hald is best known for his work in statistics and is particularly recognized for his contributions to statistical theory and methods. He was a Danish mathematician and statistician, and one of his notable contributions is the book "A History of Statistical Concepts," which traces the development of statistical ideas over time. Hald's work has significantly influenced the field of statistics, especially in areas involving the foundations of statistical inference and design of experiments.
3-D Secure
3-D Secure (Three-Domain Secure) is an online payment security protocol designed to add an additional layer of authentication for online credit and debit card transactions. The goal of 3-D Secure is to reduce fraud and unauthorized use of cards during online transactions by enabling cardholders to authenticate themselves through a verification process during checkout.
Moving average
A moving average is a statistical calculation used to analyze data points by creating averages of different subsets of the data. It is commonly used in time series analysis, financial markets, and trend analysis to smooth out short-term fluctuations and highlight longer-term trends or cycles. There are several types of moving averages, including: 1. **Simple Moving Average (SMA)**: This is the most common type, calculated by taking the arithmetic mean of a specific number of recent data points.
Ball differential
A Ball Differential, often referred to in the context of vehicles, is a type of differential that uses spherical (ball-shaped) elements to allow for the distribution of torque and enable the wheels to rotate at different speeds. This is particularly useful when a vehicle is turning, as the outside wheels cover a greater distance than the inside wheels, requiring different rotational speeds to maintain stability and traction.
Dava Sobel
Dava Sobel is an American author and science writer best known for her popular books that explore the history of science, particularly astronomy and the lives of significant scientific figures. She gained widespread recognition for her best-selling works such as "Longitude," which tells the story of the 18th-century quest to determine the longitude at sea and highlights the contributions of mathematician John Harrison.
The Journal of Physical and Chemical Reference Data (JPCRD) is a scientific journal that publishes critical evaluations and compilations of data related to physical and chemical properties of substances. It serves as a reputable source for researchers, scientists, and professionals who require reliable reference data for various physical and chemical phenomena. The journal covers a wide range of topics, including thermodynamics, quantum chemistry, spectroscopy, kinetics, and other areas related to physical and chemical measurements.
Brown–Peterson cohomology
Brown–Peterson cohomology is a homology theory in algebraic topology that is particularly focused on stable homotopy and complex cobordism. Introduced by Ronald Brown and F. P. Peterson in the context of stable homotopy theory, it serves as a tool for studying the cohomological properties of topological spaces, especially with respect to the stable homotopy category.
Anderson–Kadec theorem
The Anderson–Kadec theorem is a result in the field of functional analysis and specifically in the study of Banach spaces. It addresses the embedding of certain types of Banach spaces into weakly* compact convex sets.
