A nuclear exclusion clause is a provision commonly found in insurance policies, particularly in property and liability insurance, that excludes coverage for damages or losses resulting from nuclear incidents. This clause is designed to limit the insurer's liability in the event of a nuclear accident, explosion, or radiation exposure.
The Hiroshima-Nagasaki Protocol is a theoretical framework proposed for the establishment of a global nuclear weapons ban, inspired by the catastrophic impacts of the atomic bombings of Hiroshima and Nagasaki in 1945. It seeks to address the moral, humanitarian, and security implications of nuclear weapons and aims to prevent the future use of such weapons through international treaties and commitments.
Nuclear mines, also known as nuclear excavation devices, are theoretical or conceptual devices that would use nuclear explosions for large-scale digging or excavation purposes. The idea behind nuclear mines involves detonating a nuclear weapon underground to create a large cavity, potentially for purposes like mining resources, creating large underground structures, or other engineering applications. While the concept was explored during the Cold War, particularly in programs like the U.S.
Naval Submarine Base Bangor, located in Silverdale, Washington, is a United States Navy facility primarily dedicated to the support and maintenance of submarines. It serves as a crucial element of the U.S. Navy's Submarine Force and is home to various submarine-related operations, including the basing of Ohio-class ballistic missile submarines (SSBNs) and guided missile submarines (SSGNs).
Nuclear latency refers to the period during which a state possesses the technological and material capability to develop nuclear weapons but has not yet done so. This concept reflects a situation where a nation has the necessary knowledge, infrastructure, and resources that would allow it to build nuclear weapons relatively quickly if it chose to. States with nuclear latency are often categorized based on their level of preparedness and the political context surrounding their decision-making regarding nuclear weapons.
Neutron detection refers to the measurement and identification of neutrons, which are neutral subatomic particles found in the nucleus of atoms. Neutrons play a crucial role in nuclear reactions, astrophysics, and various applications in science and industry. Neutron detection is important in several fields, including: 1. **Nuclear Safety and Security**: Detecting neutrons is vital for monitoring nuclear reactors, safeguarding nuclear materials, and preventing illicit trafficking of radioactive substances.
Femtosecond pulse shaping refers to the manipulation and control of ultrashort laser pulses, typically in the femtosecond range (10^-15 seconds). These pulses are extremely brief, allowing researchers and technologists to study and interact with fast processes in physical, chemical, and biological systems at a time resolution that was previously unattainable.
An output coupler is an essential component used in laser systems and certain types of optical cavities. It serves the purpose of allowing a portion of the light generated within the laser cavity to exit while reflecting the remainder back into the cavity to sustain the lasing process. Output couplers are typically partially reflective mirrors, with specific reflectivity characteristics tailored to the requirements of the laser.
Self-pulsation refers to a phenomenon in various physical systems where an oscillation or fluctuation occurs spontaneously, without the need for external periodic driving forces. This behavior can be observed in several contexts, including: 1. **Optics and Lasers**: In certain laser systems, self-pulsation can occur when the gain medium's properties and the feedback from the cavity lead to oscillations in the output intensity of the laser beam.
"Elektronika" is a journal that typically focuses on research and developments in the field of electronics, including areas such as electronic engineering, circuit design, systems, and related technologies. Journals like Elektronika publish peer-reviewed articles, research papers, and studies that contribute to the advancement of knowledge in electronics and its applications.
Hund's first rule by Ciro Santilli 37 Updated 2025-07-16
Higher spin multiplicity means lower energy. I.e.: you want to keep all spins pointin in the same direction.
The Google Story Chapter 21. A Virtual Library mentions that Paul Allen was interested in trying to create something like the "Final Encyclopedia" from this book. This is somewhat the same motivation for Google Books and Google's activities more broadly, as shown in their organise the world's information mission statement.

These are websites that offer somewhat overlapping services, many of which served inspirations, and why we think something different is needed to achieve our goals.
Notably, OurBigBook is the result of Ciro Santilli's experiences with:

Xah Lee by Ciro Santilli 37 Updated 2025-07-16
fuseki.net/home/List-of-Patreon-Subs-with-Justification.html describes him well:
Outsider, formerly homeless, extreme person interested in CS and culture. Self-publishes a website with thousands of tutorial / opinion pages. Possibly similar to Sam Sloan - extremely productive, wide interests, obsessive, and pretty disagreeable.
Homepage xahlee.org/ says:
Siphon my knowledge into your brain. Assimilate my sensibilities to your spine.
Nice Second brain vibe.

The scene happens after the Americans seem to have had sucess in arming the Taliban in the 1980s to fight the Soviets, and then they decide to stop all monetary help to rebuild the country, which then leads to a terrorism threat many years later.

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.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
