This is apparently the most important III-V semiconductor, it seems to actually have some applications, see also: gallium arsenide vs silicon.
Trying to use gallium arsenide was Seymour Cray's fatal last flaw as mentioned at The Supermen: The Story of Seymour Cray by Charles J. Murray (1997).
The Supermen: The Story of Seymour Cray by Charles J. Murray (1997) page 4 mentions:
Cray wanted his new machine to employ circuits made from a material called gallium arsenide. Gallium arsenide had achieved limited success, particularly in satellite communications and military electronics. But no one had succeeded with it in anything so complicated as a computer. In the computer industry, engineers had developed a saying: "Gallium arsenide is the technology of the future," they would say. "And it always will be."
Bozenna Pasik-Duncan is a mathematician known for her contributions to various fields including mathematics education, differential equations, and dynamical systems. She has been involved in research and has published numerous papers and articles. Additionally, she has been active in promoting mathematics education and has engaged in outreach activities to inspire and educate students in mathematics.
W. Ross Ashby, or William Ross Ashby (1903–1972), was a British cybernetician and psychiatrist known for his contributions to the fields of cybernetics, systems theory, and complexity science.
A smart host is a type of mail server that acts as an intermediary between a sending mail server and the final destination mail server. It is typically used in email systems to improve the efficiency and reliability of email delivery. Here are some key characteristics and functions of a smart host: 1. **Relay Functionality**: A smart host can relay emails from one domain to another. It handles outgoing emails from local users and forwards them to the recipient's email server.
Tensors are mathematical objects that generalize scalars, vectors, and matrices to higher dimensions. They are fundamental in various fields, including physics, engineering, and machine learning, particularly in deep learning. Here’s a brief overview of what tensors are: 1. **Definition**: A tensor is essentially a multi-dimensional array that can be used to represent data. Tensors can have any number of dimensions. - A **scalar** (a single number) is a 0-dimensional tensor.
The Plebanski tensor is a mathematical object that arises in the context of general relativity and, more specifically, in the formulation of gravity in terms of differential forms and as part of the theory of 2-forms. It is particularly useful in formulations of Einstein's general relativity that are based on the variational principle and are related to the formulation of gravity as a gauge theory.
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!
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.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
