A Tracking Signal is a statistical measure used in forecasting and supply chain management to evaluate the accuracy of a forecasting model. It helps to determine whether a forecasting method is biased and whether it systematically overestimates or underestimates actual demand.
The Partial Autocorrelation Function (PACF) is a statistical tool used in time series analysis to measure the degree of association between a time series and its own lagged values, while controlling for the effects of intervening lags. It helps to identify the direct relationship between the current value of the series and its past values, excluding the influence of other lags.

Attosecond physics is a branch of physics that deals with phenomena occurring on the timescale of attoseconds (1 attosecond = \(10^{-18}\) seconds). This field primarily focuses on understanding electronic processes in atoms, molecules, and materials, as these processes often happen very rapidly—typically on the order of tens to hundreds of attoseconds.

A Graph-encoded map is a representation of spatial information using graph theory concepts. In this context, a graph consists of nodes (or vertices) and edges (or connections) that connect these nodes. Graph-encoded maps are often used in various fields, such as computer science, transportation, geography, and robotics, to model and analyze complex relationships and pathways in spatial environments.
The Grothendieck trace theorem is a result in algebraic geometry and algebraic topology that connects the concepts of trace, a type of linear functional, with the notion of duality in the setting of coherent sheaves on a variety or topological space. While often discussed in various contexts, it is particularly notable in relation to étale cohomology and L-functions in number theory.
An essentially finite vector bundle is a specific type of vector bundle that arises in the context of algebraic geometry and differential geometry. While there isn’t a universally accepted definition across all mathematical disciplines, the term generally encapsulates the idea of a vector bundle that has a finite amount of "variation" in some sense.

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.
