These games include a variety of genres such as fighting, racing, and shooting. 2. **ARCADE (Algorithm for Real-time Comparison and Data Extraction)**: A software or algorithm used in specific technical fields, particularly for data analysis or machine learning.
The Cosmic Anisotropy Polarization Mapper (CAPMap) is a scientific experiment designed to study the cosmic microwave background (CMB) radiation. The CMB is the remnant radiation from the Big Bang and provides a wealth of information about the early universe, its formation, and evolution. CAPMap's primary focus is on measuring the polarization of the CMB.
The Australia Telescope Compact Array (ATCA) is an astronomical facility located near Narrabri in New South Wales, Australia. It consists of an array of six antennas that work together to observe radio waves from celestial objects. The array is designed to operate at various frequencies, primarily in the UHF (Ultra High Frequency) and microwave bands.
The Degree Angular Scale Interferometer (DASI) is an astronomical instrument designed to measure the temperature fluctuations of the Cosmic Microwave Background (CMB) radiation. Specifically, it focuses on mapping the anisotropies in the CMB across a significant portion of the sky, which provides valuable insights into the early universe, cosmology, and the large-scale structure of the universe.
Planck was a space observatory launched by the European Space Agency (ESA) in 2009. It was part of the Cosmic Vision program and was designed to study the cosmic microwave background (CMB) radiation, which is the afterglow of the Big Bang. The spacecraft aimed to map the CMB with high sensitivity and angular resolution, providing crucial insights into the early universe, its composition, and the fundamental properties of cosmology.
The Washington Large Area Time Coincidence Array (WALTA) is a scientific experiment designed primarily for astrophysics research, particularly in the study of cosmic ray and gamma-ray astrophysics. It's part of the efforts to detect high-energy cosmic rays and other high-energy particles from astronomical events. WALTA features an array of detectors spread over a large area, which enables it to capture coincident signals from cosmic events that may generate multiple muons or other particles that hit the ground simultaneously.
The Viper Telescope, officially known as the Viper (Vera C. Rubin Observatory's) telescope, is a key component of the Vera C. Rubin Observatory located in Chile. This observatory is designed to conduct the Legacy Survey of Space and Time (LSST), which will provide an unprecedented survey of the sky over a ten-year period.
The Advanced Composition Explorer (ACE) is a NASA spacecraft launched on August 25, 1997, with the primary mission of studying particles of solar, interstellar, interplanetary, and cosmic origins. ACE operates in a highly elliptical orbit around the Earth, allowing it to continuously measure the composition of various particles in different regions of the solar system.
The CLOUD (Cosmics Leaving OUtdoor Droplets) experiment is a research initiative conducted at the CERN (European Organization for Nuclear Research) facility. It aims to understand how cosmic rays influence cloud formation in the atmosphere, which in turn affects climate. The main idea behind the experiment is to investigate the role of aerosols, which are tiny particles suspended in the atmosphere, and how they are formed and modified by cosmic rays.
"The Fabric of Reality" is a book written by philosopher David Deutsch, published in 1997. In this work, Deutsch explores the foundations of knowledge, reality, and the relationships between physics, computer science, and philosophy. He presents a unified theory that attempts to weave together disparate strands of knowledge in these fields, proposing that they can be understood through the lens of a few fundamental principles. Deutsch argues for the importance of explanations in science and posits that good explanations are key to understanding reality.
"The Grand Design" is a popular science book written by physicists Stephen Hawking and Leonard Mlodinow, published in 2010. In this work, the authors explore fundamental questions about the nature of the universe, addressing concepts like the origins of the cosmos, quantum mechanics, and the role of a creator in the universe's design.
"The Universe for Beginners" typically refers to introductory materials or resources designed to explain the basic concepts and principles of the universe, cosmology, and astrophysics in an accessible manner. This could include books, documentaries, online courses, or educational websites that aim to teach non-experts about topics such as the nature of galaxies, stars, planets, black holes, the Big Bang theory, dark matter, and dark energy, as well as the fundamental laws that govern the cosmos.
"Our Mathematical Universe" is a concept that refers to a philosophical and scientific perspective on the nature of reality, posited by the physicist Max Tegmark. This idea is extensively discussed in his book titled "Our Mathematical Universe: My Quest for the Ultimate Nature of Reality," published in 2014. Tegmark proposes that the physical universe is not just described by mathematics, but that it is fundamentally mathematical in nature. He suggests that all structures that exist mathematically exist physically as well.

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.
