Asperity in the context of faults refers to the roughness or irregularities on the surfaces of a fault line—specifically, the areas where two tectonic plates or rock masses meet and slide past one another. These surfaces are not perfectly smooth; instead, they contain protrusions or rough spots that can lock together under stress.
Gilding metal is an alloy typically composed of copper and zinc, with a higher copper content than that found in brass. It is primarily known for its use in applications that require a gold-like appearance, as it can be plated with gold to achieve a decorative finish. The typical composition of gilding metal is around 90% copper and 10% zinc, although variations may exist.
A "sealed round" typically refers to a type of funding round in a startup's fundraising process. In this context, it signifies that the round of financing has been formally closed and that all the capital from investors has been secured. Once a round is sealed, the startup usually will not accept any more investments for that round and will focus on utilizing the capital raised to achieve specific milestones. In a broader context, the term "sealed round" can also refer to the specifications of particular ammunition.
A shot tower is a structure used historically to manufacture lead shot, which is small, spherical pellets made of lead that are commonly used in shotgun shells and other ammunition. The basic principle of a shot tower is relatively simple: molten lead is poured from a height into water or another substance that cools the molten lead into small spheres as it falls. Here’s how the process typically works: 1. **Melting the Lead**: Lead is heated until it becomes molten.
The Sundial Cannon is a unique timekeeping device that combines the principles of a sundial and a cannon. It operates as a sundial, using the position of the sun to indicate the time of day. However, its distinct feature is that it fires a cannon at a designated time, usually at noon, to provide an audible signal of the time. In many cases, such cannons were historically used in harbor towns or military installations to mark the hour for sailors and civilians alike.

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.
