IBM Research is the research and development division of IBM (International Business Machines Corporation). It is known for its focus on innovation and advancing technology in various fields, including computing, artificial intelligence, quantum computing, data analytics, and more. Computer scientists at IBM Research work on a wide range of projects and initiatives that aim to push the boundaries of what is possible with technology.
Icosian calculus is a mathematical concept related to the study of graphs and polyhedra, particularly focusing on the geometric properties and relationships of the icosahedron. It is often associated with the work of mathematicians like William Rowan Hamilton, who developed the Hamiltonian path and cycle concepts, utilizing the structure of polyhedra for mathematical modeling.
An impartial game is a type of combinatorial game in which the possible moves available to each player depend only on the current state of the game, and not on which player is currently taking their turn. This means that the options available to both players are the same regardless of who is playing. In impartial games, the rules apply equally to both players, and the game ends when there are no legal moves left.
Incurred but not reported (IBNR) refers to insurance claims that have occurred but have not yet been reported to the insurer. This concept is particularly important in the context of insurance reserves and actuarial science, as it represents a liability for the insurance company. IBNR is significant for several reasons: 1. **Claims Development**: Insurance claims can take time to be reported, especially in certain lines of insurance like health, workers' compensation, or auto insurance.
Indonesian physicists are scientists from Indonesia who specialize in the field of physics. They may work in various areas of physics, such as theoretical physics, experimental physics, applied physics, and related fields. These physicists can be involved in academic research, teaching at universities, working in industrial applications, or contributing to government and non-profit research organizations. Indonesia has a growing community of physicists, with several universities and research institutions focused on physics and related disciplines.
The Infinite Difference Method (IDM) is a numerical technique used primarily in the field of differential equations and computational mathematics. It is particularly useful for solving partial differential equations (PDEs) and can be applied in various engineering fields, physics, and finance. ### Key Concepts of the Infinite Difference Method 1. **Difference Equations**: The IDM transforms continuous differential equations into difference equations by discretizing the problem.

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.
