The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is an international treaty that aims to ban all nuclear weapon test explosions and any other nuclear explosions. The treaty was adopted by the United Nations General Assembly on September 10, 1996, but has not yet entered into force because it requires ratification by 44 specific countries that are nuclear-capable or part of the nuclear supply group.
Treaties establishing nuclear-weapon-free zones (NWFZs) are international agreements that create specific regions where the development, testing, deployment, and possession of nuclear weapons are prohibited. These treaties serve to promote global peace, security, and non-proliferation of nuclear arms by creating designated areas where states collectively agree not to acquire nuclear weapons. The establishment of NWFZs is seen as a way to enhance regional security, prevent the spread of nuclear weapons, and promote disarmament.
The Anti-Ballistic Missile (ABM) Treaty was a key arms control agreement signed between the United States and the Soviet Union on May 26, 1972. The treaty aimed to limit the deployment of anti-ballistic missile systems, which are designed to intercept and destroy incoming ballistic missiles. Key features of the ABM Treaty included: 1. **Limitations on ABM Systems**: The treaty allowed each signatory to deploy only a limited number of ABM systems.
A Bomb Tower is a defensive building in the mobile strategy game "Clash Royale." It serves as a structure that can defend against enemy troops and deal area damage. When placed, the Bomb Tower targets ground units and has a long range, making it effective at deterring and damaging incoming enemy troops, particularly swarm units or ground-based attackers. The Bomb Tower has a moderate hit points and can withstand a fair amount of damage from enemy attacks.
Emu Field is a locality in South Australia, situated in the north-western part of the state. It is primarily known for its proximity to the Emu Field Nuclear Research Facility, which has been used for various scientific and defense-related purposes, including nuclear testing in the past. The area is characterized by its arid environment and is part of the larger region of the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, known for its Indigenous cultural heritage.
The AN-52 is a type of tactical nuclear bomb developed by the United States in the mid-20th century. Specifically, it was designed for use by the U.S. Air Force and was a part of the U.S. nuclear arsenal during the Cold War. The bomb was developed to be carried by strategic bombers, and it featured a relatively low yield compared to larger thermonuclear weapons.
In meteorology, a "blank" on a weather map typically refers to an area that lacks specific weather data or forecasts. This could indicate several things, such as: 1. **Data Absence**: There might be no weather stations in that area providing real-time data. 2. **Limited Forecast Models**: Certain regions may not be covered adequately by forecasting models, leading to a lack of predicted weather patterns.
Equivalent to Lagrangian mechanics but formulated in a different way.
Motivation: Lagrangian vs Hamiltonian.
TODO understand original historical motivation, www.youtube.com/watch?v=SZXHoWwBcDc says it is from optics.
Intuitively, the Hamiltonian is the total energy of the system in terms of arbitrary parameters, a bit like Lagrangian mechanics.
Bibliography:
The key difference from Lagrangian mechanics is that the Hamiltonian approach groups variables into pairs of coordinates called the phase space coordinates:This leads to having two times more unknown functions than in the Lagrangian. However, it also leads to a system of partial differential equations with only first order derivatives, which is nicer. Notably, it can be more clearly seen in phase space.
- generalized coordinates, generally positions or angles
- their corresponding conjugate momenta, generally velocities, or angular velocities

The Google Story Chapter 11. "The Google Economy" comments:
As they saw it, generation one was AltaVista, generation two was Google, and generation three was Teoma, or what Ask Jeeves came to refer to as Expert Rank. Teoma's technology involved mathematical formulas and calculations that went beyond Google's PageRank system, which was based on popularity. In fact, the concept had been cited in the original Stanford University paper written by Sergey Brin and Larry Page as one of the methods that could be used to rank indexed Web sites in response to search requests. "They called their method global popularity and they called this method local popularity, meaning you look more granularly at the Web and see who the authoritative sources are," Lanzone said. He said Brin an Page had concluded that local popularity would be exceedingly difficult to execute well, because either it would require too much processing power to do it in real time or it would take too long.
googlesystem.blogspot.com/2006/03/expertrank-authoritative-search.html mentionsand:
ExpertRank is an evolution of IBM's CLEVER project, a search engine that never made it to public.
The difference between PageRank and ExpertRank is that for ExpertRank the quality of the page is important and that quality is not absolute, but it's relative to a subject.
There are other more recent algorithms with similar names, and are prehaps related:

This is how you transform the Lagrangian into the Hamiltonian.
Ivar Jacobson is a Swedish computer scientist known for his significant contributions to the field of software engineering. He is best known for developing the Unified Software Development Process (USDP) and for his role in the creation of the Unified Modeling Language (UML), which is a standardized way of visualizing the design of a system. Jacobson's work has had a profound impact on object-oriented software development and practices related to requirements engineering, software architecture, and iterative development.

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.
