The Lebombo bone is an archaeological artifact that consists of a baboon fibula with 29 distinct notches. It was discovered in the Lebombo Mountains, which lie on the border between South Africa and Swaziland (now Eswatini). The bone is estimated to be around 35,000 to 65,000 years old and is thought to be one of the oldest known counting tools.
TRPM6 (Transient Receptor Potential Melastatin 6) is a protein that functions as a channel for transporting ions across cell membranes. It is a member of the TRP (Transient Receptor Potential) channel family, specifically the melastatin subfamily. TRPM6 is primarily known for its role in magnesium homeostasis within the body. The protein is expressed in various tissues, including the kidneys and intestines, where it is crucial for the absorption of magnesium from the diet.
The Lwów School of Mathematics was a prominent mathematical community that flourished in the early 20th century in Lwów (now Lviv, Ukraine). It emerged in the interwar period and was characterized by a collaborative and innovative spirit among several distinguished mathematicians.
"Legato" can refer to a couple of different concepts, depending on the context: 1. **In Music**: Legato is a musical term indicating that notes should be played or sung smoothly and connectedly, without any perceptible interruption between them. This contrasts with staccato, where notes are played in a detached or separated manner. When musicians see the term "legato" in sheet music, they typically interpret it to mean that they should use techniques that maintain a flowing sound.

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.
