Process Simulation Software FREE Download - Aspen Hysys versus DWSim | COCO by Jeferson Costa (2020)
Source. Jeferson, a Brazilian from Petrobras, is the creator of the open source DWSim software, and in this video he gives a quick demo of his software and compares it briefly to aspen HYSYS, which appears to be the golden paid reference implementation.Aspen Hysys Introduction by Emmanuel Oloyede (2016)

The first one with such complexity that was uncovered.
The ATP synthase complex is so large that Power, Sex, Suicide by Nick Lane (2006) page 123 contains a cryoEM image of several ATP synthases on small membrane vesicles, this is the paper: pubs.acs.org/doi/abs/10.1021/bi00437a031# under a fucking paywall.

A computable number is a real number that can be calculated to any desired degree of precision by a finite, deterministic procedure, such as a computer algorithm or a mathematical process. In other words, a computable number is one for which there exists a method (or algorithm) that can produce its digits when given enough time and resources.
The Deflationary Theory of Truth is a philosophical perspective that downplays the significance of the concept of truth. Rather than viewing truth as a substantial property that sentences possess, deflationists argue that the notion of truth can be expressed in a simplified or trivial way. One of the key ideas behind deflationary theories is that asserting that a statement is true does not provide any additional information beyond the statement itself.
Pluralist theories of truth propose that there is not a single, exclusive conception of truth but rather multiple ways of understanding or defining truth that can be valid depending on the context. This perspective acknowledges that different domains of inquiry may require different standards of truth, and thus what is considered true in one context may not apply in another.
As of my last update in October 2023, Lisa Lix is a brand that specializes in creating a variety of lifestyle products, particularly focusing on innovative drinkware. Their offerings often include reusable cups, bottles, and other containers designed to be environmentally friendly and stylish. The products typically emphasize sustainability, functionality, and aesthetic appeal, catering to customers who value both practicality and design in their daily lives.
In the context of physics, particularly in theoretical and mathematical physics, a "supergroup" is a generalization of a group that incorporates both commutative (bosonic) and anti-commutative (fermionic) elements. This concept arises from the study of supersymmetry, which is a theoretical framework that suggests a symmetry between bosons and fermions.
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
