The United States Exploring Expedition, also known as the Wilkes Expedition, was a significant scientific and exploratory mission led by Lieutenant Charles Wilkes of the United States Navy. It took place from 1838 to 1842 and aimed to explore and survey the Pacific Ocean and its surrounding regions. The expedition was one of the first to systematically explore and chart large portions of the Pacific, including the coasts of North America, South America, and the islands of the South Pacific.
Shawn Carlson is a notable figure in the context of science communication, particularly in the field of skepticism and critical thinking. He is best known for his work as a scientist, author, and for promoting the importance of scientific inquiry and the testing of claims through proper methodology. Carlson is also recognized for his involvement with the Committee for Skeptical Inquiry (CSI) and for engaging in discussions and debates about pseudoscience and paranormal claims.
Management systems are structured frameworks that organizations use to manage their processes, ensure quality, improve efficiency, and achieve strategic objectives. These systems help integrate various organizational functions and standardize operations across different departments. They often include policies, procedures, resources, and responsibilities necessary to implement and maintain the system effectively. Some key types of management systems include: 1. **Quality Management Systems (QMS)**: Focus on improving the quality of products and services.
A single transmembrane protein that moves ATP out and ADP in of the mitochondrion. So crucial.

Good video showing what appears to be the adenine nucleotide translocator. although they don't use that name, instead saying ADP/ATP carrier.
The video also briefly depicts the ATP synthase and the mitochondrial phosphate carrier protein.

Sum of three cubes by Ciro Santilli 40 Updated 2025-07-16
Compared to Waring's problem, this is potentially much harder, as we can go infinitely negative in our attempts, there isn't a bound on how many tries we can have for each number.
In other words, it is unlikely to have a Conjecture reduction to a halting problem.

Mauritius, like many countries, primarily uses the metric system for most measurements, including length (meters), weight (kilograms), and volume (liters). However, some traditional units may still be in use informally in various contexts, particularly in agriculture or cooking.
Gibbs free energy by Ciro Santilli 40 Updated 2025-07-16
TODO understand more intuitively how that determines if a reaction happens or not.
At least from the formula we see that:
  • the more exothermic, the more likely it is to occur
  • if the entropy increases, the higher the temperature, the more likely it is to occur
    • otherwise, the lower the temperature the more likely it is to occur
A prototypical example of reaction that is exothermic but does not happen at any temperature is combustion.

Somalia uses a combination of both traditional Somali units of measurement and the metric system, which is the official system of measurement in the country. Here are some of the traditional Somali units of measurement: 1. **Length:** - **Courage (cag)**: A traditional unit of length, often refers to a person's height or stature. - **Fool**: A unit that can refer to the length of a piece of string or rope, often about a foot.

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
