Aircraft Meteorological Data Relay (AMDAR) is a system used for collecting and transmitting meteorological data from aircraft in flight. The primary purpose of AMDAR is to provide real-time atmospheric data to meteorological agencies and research institutions, which can enhance weather forecasting and climate monitoring.
Basic example tested on SQLite 3.40.1, Ubuntu 23.04:output:
sqlite3 :memory: 'select 1 union select 2'

Two columns two rows:output:
sqlite3 :memory: <<EOF
select * from (values (1, 2), (2, 3))
union
select * from (values (2, 3), (3, 4))

The Aircraft Reactor Experiment (ARE) was a project developed by the United States in the late 1950s to explore the feasibility of using nuclear power for aircraft propulsion. Conducted by the Los Alamos National Laboratory and the Atomic Energy Commission, the primary objective of the experiment was to determine if a nuclear reactor could be designed for use in an aircraft engine and if it could provide sufficient thrust and power for sustained flight.
A trust anchor is a critical component in a security framework, particularly in cryptography and network security. It serves as a foundational point of trust in a system that relies on digital certificates and public key infrastructure (PKI). Trust anchors are typically represented by a trusted public key or a certificate that is used to establish a chain of trust for digital communications and transactions.
Airfix is a well-known British manufacturer of plastic model kits, primarily focusing on military vehicles, aircraft, ships, and figures. Founded in 1939 by Nicholas K. Churchill, the brand gained popularity for its detailed and historically accurate models that cater to hobbyists and collectors of all ages. Airfix kits come in various sizes and complexity levels, making them accessible for both beginners and experienced model builders.
Air traffic control (ATC) systems are essential components of the air transportation system, responsible for ensuring the safe and efficient movement of aircraft in the airspace and on the ground at airports. These systems assist pilots in navigating airspace, managing traffic, and preventing collisions. Here are the key aspects of air traffic control systems: ### 1.
The Airy disk is a pattern of light observed when a point source of light, such as a distant star, is imaged through a circular aperture, such as a lens or an optical telescope. It occurs due to the diffraction of light, which causes waves to spread out when passing through the aperture. The Airy disk is characterized by a central bright spot, known as the Airy central maximum, surrounded by a series of concentric dark and bright rings.

MI1, or Military Intelligence Section 1, was a section of British military intelligence that was responsible for gathering and analyzing intelligence regarding potential threats to British national security. It played a significant role during World War I and II, focusing on issues such as espionage and counterintelligence. The MI designation has been associated with various sections of British intelligence, including MI5 (domestic intelligence) and MI6 (foreign intelligence).
Ai Shōka (愛唱歌) typically refers to songs that are beloved or cherished, often showcasing deep emotional connections. The term is commonly used in Japanese to describe songs that are sung with affection or have special significance to an individual or a group. In a broader context, it can refer to a genre of music or songs that resonate on a personal level, frequently evoking nostalgia or deep feelings.
Aizerman's conjecture is a significant hypothesis in the field of control theory and linear systems. Proposed by M. Aizerman in the 1950s, the conjecture pertains to the stability of linear systems, particularly regarding the behavior of polynomial functions and their roots. Specifically, Aizerman's conjecture suggests that if a linear continuous-time system is stable for some feedback gain, then it remains stable for all feedback gains greater than that value.

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!
Intro to OurBigBook
. 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.
