The PC-1, or PC-1 computer, refers to a specific model of personal computer that was introduced by various manufacturers during the early evolution of personal computing. However, the term "PC-1" isn't as commonly recognized as others, such as the IBM PC or Apple's early offerings. The most widely known "PC" refers to IBM's Personal Computer, which debuted in 1981 and set the standard for compatible personal computers.
chemistry.stackexchange.com/questions/7696/how-do-i-distinguish-between-internal-energy-and-enthalpy/7700#7700 has a good insight:
To summarize, internal energy and enthalpy are used to estimate the thermodynamic potential of the system. There are other such estimates, like the Gibbs free energy G. Which one you choose is determined by the conditions and how easy it is to determine pressure and volume changes.
Sukhoy Nos is a cape located in the northeastern part of Lake Baikal in Russia. It is known for its picturesque landscapes and natural beauty. Sukhoy Nos is a popular spot for outdoor activities such as hiking, fishing, and photography, attracting nature enthusiasts and tourists. The area is part of the Baikal Nature Reserve, which is a UNESCO World Heritage site and is noted for its unique ecosystems and biodiversity.
A fuzzy control system is a type of control system that uses fuzzy logic instead of traditional binary sets (true/false or 1/0) to make decisions or control processes. Fuzzy logic is a form of many-valued logic that deals with reasoning that is approximate rather than fixed and exact. This makes it particularly useful for complex systems where uncertainty or imprecision is a factor.
A critical system refers to a system that is essential for the functioning of a larger framework or operation, where failure or malfunction could result in significant consequences, such as safety hazards, financial loss, or disruption of services. Critical systems are commonly found in various domains, including: 1. **Safety-Critical Systems**: These are systems where a failure could lead directly to loss of life, significant property damage, or environmental harm.
As mentioned at buzzard.ups.edu/courses/2017spring/projects/schumann-lie-group-ups-434-2017.pdf, what the symmetry (Lie group) acts on (obviously?!) are the Lagrangian generalized coordinates. And from that, we immediately guess that manifolds are going to be important, because the generalized variables of the Lagrangian can trivially be Non-Euclidean geometry, e.g. the pendulum lives on an infinite cylinder.

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.
