The Centauro event is a notable incident in the field of astronomy and astrophysics, particularly involving the Centaur class of celestial objects. Centaurs are icy bodies that orbit between the outer planets, generally characterized by unstable orbits that can be affected by the gravity of nearby planets. However, there may be specific events or discoveries associated with Centaur objects that have been labeled as "Centauro events.
The Compton-Getting effect is a phenomenon in astrophysics and cosmic ray physics related to the movement of cosmic rays and their interaction with the Earth's atmosphere or a moving observer. Named after the physicist Arthur Holly Compton, this effect describes how the observed intensity and energy distribution of cosmic rays change due to the motion of the observer relative to the incoming cosmic rays. When an observer (such as Earth) moves through space, it can encounter cosmic rays that have a specific energy spectrum.
OREOcube is a concept or product developed by Nabisco, which is a brand of Mondelēz International, known for producing Oreo cookies. The OREOcube is essentially a three-dimensional cube made up of Oreo cookie elements that can be manipulated and assembled in various ways, often focusing on creativity, construction, and play. While the specifics may vary, the OREOcube is typically aimed at both adults and children, combining the familiar enjoyment of Oreos with an interactive experience.
The Book of Giants is an ancient Jewish apocryphal text that is part of the Enochic literature, traditionally associated with the Book of Enoch. Although it is not included in the canonical Bible, it provides insight into Jewish apocalyptic thought and mythology.
Matías Zaldarriaga is a physicist known for his work in cosmology, especially in the fields related to the Cosmic Microwave Background (CMB) and large-scale structure in the universe. He has contributed to understanding the early universe, inflationary models, and the formation of large-scale structures.
Cryptographers are individuals who specialize in the study and practice of cryptography, which is the science of securing communication and information by transforming it into a format that cannot be easily understood by unauthorized individuals. Cryptography involves various techniques, including algorithms, protocols, and encryption methods, to ensure data confidentiality, integrity, authentication, and non-repudiation. Cryptographers work on designing and analyzing these algorithms and protocols to ensure they are robust against attacks.
The timeline of electrical and electronic engineering encompasses numerous advancements and milestones that have contributed to the field as we know it today. Here’s a brief overview of key events and developments: ### 19th Century - **1800**: Italian scientist Alessandro Volta invented the voltaic pile, the first chemical battery that could provide a steady source of electricity. - **1820**: Hans Christian Ørsted discovered that electric currents create magnetic fields, forming the basis of electromagnetism.
Counts per minute (CPM) is a measurement often used in various fields, including medical diagnostics, radiation measurement, and research to quantify the frequency of events occurring within a one-minute time interval. Here are a few examples of its applications: 1. **Medical Diagnostics**: In the context of heart rate monitoring, CPM can refer to the number of heartbeats counted in one minute. It is equivalent to beats per minute (BPM).
Gibbs sampling is a Markov Chain Monte Carlo (MCMC) algorithm used for generating samples from the joint distribution of a set of random variables, especially when direct sampling is complex or infeasible. It is particularly popular in Bayesian statistics, where it's used to perform posterior inference. ### Key Concepts of Gibbs Sampling: 1. **Goal**: The main purpose of Gibbs sampling is to approximate the joint distribution of multiple variables.
The Gibbs-Helmholtz equation is a thermodynamic relation that connects the Gibbs free energy (G) and the enthalpy (H) of a system to its temperature (T) and entropy (S). It is often expressed in the context of changes in standard conditions and is particularly useful in determining equilibrium constants and reaction spontaneity.
The American Society for Precision Engineering (ASPE) is a professional organization that focuses on the advancement of precision engineering. Founded in 1986, ASPE serves as a platform for professionals in the field to share knowledge, collaborate on research, and promote innovations in precision engineering practices and technologies. ASPE aims to foster the development of precision engineering by: 1. **Facilitating Networking**: Bringing together engineers, researchers, and industry professionals from academia and various sectors to build connections and share expertise.
A Gamma-Ray Burst Optical/Near-Infrared Detector (GRB OND) is an instrument designed to detect and study optical and near-infrared (NIR) emissions from gamma-ray bursts (GRBs). Gamma-ray bursts are among the most energetic events in the universe, typically associated with the collapse of massive stars or the merger of neutron stars, leading to the production of gamma-ray radiation.
The Friedrichs extension is a concept from functional analysis and operator theory, particularly related to self-adjoint operators in the context of quantum mechanics and partial differential equations. It provides a way to extend an unbounded symmetric operator to a self-adjoint operator, which is crucial because self-adjoint operators have well-defined spectral properties and their associated physical observables are mathematically rigorous.
Americium-241 (Am-241) is a radioactive isotope of the element americium, which is part of the actinide series in the periodic table. Americium is a synthetic element, first produced in 1944 by Glenn T. Seaborg and his team at the University of California, Berkeley. Am-241 has a half-life of approximately 432.2 years, meaning it takes that amount of time for half of a sample of this isotope to decay.
An Amiga Disk File (ADF) is a file format used to store the contents of a disk from the Amiga personal computer. The Amiga, developed by Commodore in the 1980s and 1990s, used floppy disks for software distribution. An ADF file is essentially a digital image of an Amiga floppy disk, capturing the complete disk data, including the operating system, applications, and game software.
Amiga emulation software refers to programs and applications that allow users to simulate the hardware and operating system of the Amiga computers, which were popular in the 1980s and 1990s. Amiga emulators enable users to run Amiga games, applications, and demos on modern hardware like Windows, macOS, and Linux systems.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
