Email management refers to the systematic organization, handling, and maintenance of email communications and accounts to improve efficiency, productivity, and effectiveness in both personal and professional settings. It encompasses various practices, tools, and strategies aimed at managing the influx of emails in a way that minimizes clutter and maximizes accessibility and usefulness. Key components of email management include: 1. **Organization**: Setting up folders, labels, or categories to sort emails based on criteria such as project, priority, sender, or topic.
Email sender accreditation refers to the process through which email senders can validate their identity and establish their reputation as trustworthy senders within the email ecosystem. This is often critical for ensuring that emails are delivered to recipients’ inboxes rather than being filtered out as spam or unwanted mail.
A Fully Qualified Domain Name (FQDN) is the complete domain name for a specific host or resource on the internet. An FQDN specifies its exact location within the Domain Name System (DNS) hierarchy, and it includes the host name and the domain name, including all higher levels of the domain. An FQDN consists of: 1. **Host Name**: The specific name for a particular computer or device within the domain (e.g.
The Global Address List (GAL) is a feature commonly used in email systems, particularly in Microsoft Exchange and Microsoft 365 environments. It is essentially a directory of all the users, groups, and resources within an organization's domain. The GAL allows users to easily find and contact coworkers, departments, and other email-enabled resources without needing to know the specific email addresses.
The Jessica Mydek hoax letter refers to a fraudulent correspondence that circulated online, in which a fictional character named Jessica Mydek supposedly wrote a letter describing her experiences and challenges. This letter gained attention for its emotional content and dramatic narrative, leading many readers to believe it was a genuine account. The letter was eventually revealed to be a hoax, prompting discussions about the dangers of misinformation, the impact of fake narratives online, and the importance of critical thinking when consuming content on the internet.
Appears to support multiple proof assistant backends including Lean, Hol and Coq.
A discussion on the Lean Zulip: leanprover.zulipchat.com/#narrow/stream/113488-general/topic/The.20Math.20Genome.20Project/near/352639129. Lean people are not convinced about the model in general it seems however.

Has conjectures feature.
Built by this dude John Mercer:He must be independently wealthy or something to do such a project? What a hero. But he seems to have jobs. On the side? Hardcore.

Does the website actually automatically check the formal proofs, or is this intended to be implemented at some point? And if yes, is it intended to allow proofs to depend on other proofs of the website (possibly by other people)
Owner:
Hi Ciro, yes we will be releasing in-browser proof assistant environments/checkers (e.g. Lean). Our goal is not to replace the underlying open-source repos (e.g. Mathlib) so the main dependency will be on the current repos; then when statement formalizations and proofs come in and are certified they can be PR'd to the respective repos. So we will be the source of truth for the informal latex code but only a stepping stone and orchestration layer on the way to the respective formal libraries.
So apparently there will be proof checking, but no dependencies between proofs, you still have to pull request everything back and face the pain.
Bell state by Ciro Santilli 40 Updated 2025-07-16
One of the four following states:
When unqualified as in "the Bell state", it generally just means .
The Bell states are entangled and non-separable. Intuitively, we can see that when we measure that state, the values of the first and second bit are strictly correlated. This is the hallmark of quantum computation: making up states where qubits are highly correlated to match a specific algorithmic answer, and opposed to uniformly random noise. For example, the Bell state circuit is a common hello world, e.g. it is used in the official Qiskit hello world.
As of my last knowledge update in October 2021, there is no widely recognized public figure or entity by the name "Lilian Brandt." It is possible that Lilian Brandt may refer to a private individual, a lesser-known personality, or a brand that has emerged after that date.
German materials scientists are professionals and researchers who specialize in the study, development, and application of materials. Their work encompasses various fields such as metallurgy, polymers, ceramics, nanomaterials, and composites. In Germany, materials science is a prominent and well-established discipline, supported by a strong network of universities, research institutions, and industries. Germany is known for its robust engineering and manufacturing sectors, particularly in automotive, aerospace, electronics, and manufacturing, making materials science a critical area of research and development.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
