The Integrated Ballistics Identification System (IBIS) is a sophisticated forensic technology used by law enforcement agencies to analyze and compare ballistic evidence, such as bullets and cartridge casings, from crime scenes. IBIS enables the capture and storage of digital images of these items, which can then be compared to a database of previously analyzed evidence.
Formal proof is useless by Ciro Santilli 37 Updated +Created
The only cases where formal proof of theorems seem to have had actual mathematical value is for theorems that require checking a very large number of case, so much so that no human can be fully certain that no mistakes were made. Some examples:

Football by Ciro Santilli 37 Updated +Created
Football is a synonym for association football, can we be done with that! The word "soccer" is an aberration.
Alexander Shapiro by Wikipedia Bot 0
Alexander Shapiro is a name that could refer to different individuals across various fields, such as academia, business, or other areas. Without more specific context, it's hard to determine exactly which Alexander Shapiro you are referring to.
High–low system by Wikipedia Bot 0
The high-low system, often referred to in various contexts such as finance, gaming, and decision-making, typically involves determining outcomes based on the highest and lowest values or scores within a specified range or set of data. In finance and trading, particularly in stock market analysis, the high-low system may refer to strategies that utilize the highest and lowest prices of a security over a certain period.
Food without photosynthesis by Ciro Santilli 37 Updated +Created
This is the future of course, fusion power to generate electricity, and then converting electricity into food somehow.
Hopefully without going through photosynthesis, which feels complicated and wasteful.
Gun harmonisation by Wikipedia Bot 0
Gun harmonization generally refers to the process of aligning or regulating firearm laws, standards, and practices across different jurisdictions to ensure consistency and safety in the use of firearms. The term can be applied in various contexts, including: 1. **Legal Harmonization**: This involves aligning laws related to gun ownership, use, and sales across different states or countries to facilitate legal clarity and reduce loopholes that can lead to gun trafficking, misuse, or inconsistencies in enforcement.
Gun chronograph by Wikipedia Bot 0
A gun chronograph is a device used to measure the velocity of projectiles, such as bullets or pellets, as they are fired from a firearm or airgun. It provides crucial data for shooters, reloaders, and ballistics experts, allowing them to understand the performance of their ammunition and firearms better. Typically, a gun chronograph consists of a pair of sensors that detect the passing projectile.
Daniel Santbech by Wikipedia Bot 0
As of my last update in October 2023, there is no widely recognized figure or concept known as "Daniel Santbech." It's possible that he could be a private individual, a person who has gained prominence after that date, or someone from a specific niche or local context that hasn't received widespread attention.

Fog computing by Ciro Santilli 37 Updated +Created
Our definition of fog computing: a system that uses the computational resources of individuals who volunteer their own devices, in which you give each of the volunteers part of a computational problem that you want to solve.
Folding@home and SETI@home are perfect example of that definition.
A combustion light-gas gun is a type of experimental firing device used primarily in research facilities and laboratories to study the behavior of materials under extreme conditions, such as high-velocity impacts. This type of gun operates by combining a fuel with an oxidizer, which is ignited to produce high-pressure gases. These gases are then used to propel a projectile at very high speeds, often exceeding the speeds achievable with traditional gunpowder-based ammunition.

"Ballistics by the Inch" (BBTI) is a research project and resource focused on the study of the relationship between the length of a firearm's barrel and the resulting velocity and performance of various ammunition types. The initiative is particularly aimed at understanding how different barrel lengths can affect the ballistic performance of handgun cartridges. BBTI conducts extensive testing with a variety of common handgun calibers and different barrel lengths, measuring the velocity of projectiles fired from these firearms.
Ballistic table by Wikipedia Bot 0
A ballistic table, also known as a ballistic coefficient table or ballistic data table, is a chart or set of data that provides information about the performance of a projectile (such as a bullet) during its flight. It typically includes values for various factors that influence the trajectory and behavior of the projectile, such as: 1. **Ballistic Coefficient (BC)**: A measure of a bullet's ability to overcome air resistance in flight. Higher BC values indicate less drag and better aerodynamic efficiency.

Pinned article: ourbigbook/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.
