Annual Fuel Utilization Efficiency (AFUE) is a measure used to evaluate the efficiency of heating appliances, such as furnaces and boilers. It indicates how effectively a heating system converts fuel into usable heat over the course of a year. The AFUE percentage represents the ratio of the annual heat output of the system to the total annual fuel input, expressed as a percentage.
Anode rays, also known as canal rays, are a type of positively charged particle beam observed in a discharge tube. They were discovered by Eugen Goldstein in 1886. Anode rays are produced when a high-voltage electrical discharge passes through a low-pressure gas, resulting in the ionization of the gas.

The Volterra series is a mathematical framework used to represent nonlinear systems in terms of their input-output relationships. Named after the Italian mathematician Vito Volterra, this series generalizes the concept of a Taylor series to handle nonlinear dynamics. ### Key Concepts: 1. **Nonlinearity**: Unlike linear systems, where output is directly proportional to input, nonlinear systems exhibit more complex behaviors. The Volterra series captures these nonlinearities systematically.

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.
